The Affidavit of Merit (AOM) was created in 1995 by the enactment of the Affidavit 
of Merit statute, N.J.S.A. 2A:53A-26A 
et seq. The statute has undergone some 
modifications since its original enactment, particularly with respect to what 
professions it applies to and what experts may sign the affidavit, it remains a 
pre-requisite for all medical malpractice actions in New Jersey.
Moreover, the earliest cases interpreting the Act 
make it clear that the purpose of the statute is “to require plaintiffs in 
medical malpractice cases to make a threshold showing that their claim is 
meritorious, in order that meritless lawsuits readily could be identified at an 
early stage of litigation.” In re Hall, 147 N.J. 379, 391 (1997).
The original statute provided that the “Licensed Person[s]” entitled 
to an AOM included dentists, physicians, podiatrists, chiropractors, reg_istered 
nurses and certain health care facilities. In 2001, physical therapists and 
pharmacists were added. Recently, midwives were added. The Affidavit of Merit statute originally 
required the expertise of the expert to be “evidenced by board certification or 
by devotion of the person’s practice sub_stantially to the general area or 
specialty involved in the action for a period of at least five years.” N.J.S.A. 
2A:53A-27.
In fact, in 2004, the statute was amended 
by the New Jersey Medical Care Access and 
Responsibility and Patients First Act; N.J.S.A . 2A:53A-37 to 42, which added 
additional requirements for experts executing affidavits. Moreover, t he latest requirements provide that if 
the defendant is a specialist or subspecialist and the care or treatment at 
issue involves that specialty or subspecialty, the expert must have specialized 
in the same specialty or subspecialty. See N.J.S.A . 2A:53A-41.
Additionally, if the defendant is board certified 
and the care at issue involved that specialty or subspe_cialty, the expert must 
be board certified in the same specialty or subspecialty or credentialed by a 
hospital to treat patients for the condition or perform the procedure in 
question; and during the year before the date of the claim, must have devoted a 
majority of her professional time to either clinical practice or the 
instruction of students in the same specialty or subspecialty.
However, if the defendant 
is a “general practitioner,” the expert witness must have devoted a majority of 
his professional time in “clinical practice as a general practitioner; or 
active clinical practice that encompasses the medical condition, or that includes 
performance of the procedure, that is the basis of the claim” or to teaching 
same. N.J.S.A . 2A:53A-41(b). 
Still, recent controversies and reported cases have arisen regarding the 
interpretation of the expert qualifications.
The Affidavit of Merit statute does not apply to contract 
claims or to assault and battery claims. See Darwin 
v. Gooberman , 339 N.J. Super. 467 (App. Div 2001) certif. denied 169 N.J. 609 (2000). It also does not apply to the elements 
of causation or damages within a malpractice case but is strictly limited to 
the deviation from the accepted standard of care.  Hubbard v. 
Reed, 168 N.J. 387 (2001) ; 
Darwin, supra at 480-481.

in part, directly or indirectly by any one or more health care facilities, and 
the predominant source of business of which is not covered by contract with 
health care facilities within the State of New Jersey and which solicit or 
accept specimens and operate predominantly in interstate commerce.
N.J.S.A. 2A:53A-27. Affidavit of lack 
of care in action for professional, medical malpractice or negligence; 
requirements
In any action for damages for personal injuries, wrongful 
death or property damage resulting from an alleged act of malpractice or 
negligence by a licensed person in his profession or occupation, the plaintiff 
shall, within 60 days 
following the date of filing of the answer to the complaint by the defendant, 
provide each defendant with 
an affidavit of an appropriate 
licensed person that there exists a reasonable probability that the care, skill or knowledge exercised 
or exhibited in the treatment, practice or work that is the subject of the 
complaint, fell outside acceptable professional or occupational standards or 
treatment practices. The court may grant no more than one additional 
period, not to exceed 60 days, to file the affidavit pursuant to this section, 
upon a finding of good cause.
In the case of an action for medical 
malpractice, the person executing the affidavit shall meet the requirements of 
a person who provides expert testimony or executes an affidavit as set forth in 
section 7 of P.L. 2004, c. 17 ( C. 2A:53A-41 ). In all other 
cases, the person executing the affidavit shall be licensed in this or any 
other state; have particular expertise in the general area or specialty 
involved in the action, as evidenced by board certification or by devotion of 
the person’s practice substantially to the general area or specialty involved 
in the action for a period of at least five years. The person shall have no 
financial interest in the outcome of the case under review, but this 
prohibition shall not exclude the person from being an expert witness in the 
case.
 
N.J.S.A. 2A:53A-41. Requirements for person giving expert 
testimony, executing affidavit
In an action alleging medical malpractice, a person shall not 
give expert testimony or execute an affidavit pursuant to the provisions of 
P.L. 1995, c. 139 ( C. 2A:53A-26 et seq.) on the appropriate 
standard of practice or care unless the person is licensed as a physician or 
other health care professional in the United States and meets the following 
criteria:
a. If the party against whom or on 
whose behalf the testimony is offered is a specialist or subspecialist 
recognized by the American Board of Medical Specialties or the American 
Osteopathic Association and the care or treatment at issue involves that 
specialty or subspecialty recognized by the American Board of Medical 
Specialties or the American Osteopathic Association, the person providing the testimony shall have specialized at the 
time of the occurrence that is the basis for the action in the same specialty 
or subspecialty, recognized by the American Board of Medical 
Specialties or the American Osteopathic Association, as the party against whom 
or on whose behalf the testimony is offered, and if the person against whom or on whose behalf the testimony is 
being offered is board certified and the care or treatment at issue involves 
that board specialty or subspecialty recognized by the American Board 
of Medical Specialties or the American Osteopathic Association, the expert witness shall be:
 
 
(1) a physician credentialed by a hospital to treat patients for the 
medical condition, or to perform the procedure, that is the basis for the claim 
or action;
(2) a specialist 
or subspecialist recognized by the American Board of Medical Specialties or the 
American Osteopathic Association who is board certified in the same specialty 
or subspecialty, recognized by the American Board of Medical Specialties or the 
American Osteopathic Association, and during the year immediately preceding the 
date of the occurrence that is the basis for the claim or action, shall have 
devoted a majority of his professional time to either:
 
(a) the active clinical practice of the same health care profession in 
which the defendant is licensed, and, if the defendant is a specialist or 
subspecialist recognized by the American Board of Medical Specialties or the 
American Osteopathic Association, the active clinical practice of that 
specialty or subspecialty recognized by the American Board of Medical 
Specialties or the American Osteopathic Association; or 
 
 
(b) the instruction of students in an accredited medical school, other 
accredited health professional school or accredited residency or clinical 
research program in the same health care profession in which the defendant is 
licensed, and, if that party is a specialist or subspecialist recognized by the 
American Board of Medical Specialties or the American Osteopathic Association, 
an accredited medical school, health professional school or accredited 
residency or clinical research program in the same specialty or subspecialty 
recognized by the American Board of Medical Specialties or the American 
Osteopathic Association; or
b. If the party against whom or on whose behalf the testimony is offered is a general practitioner, the expert 
witness, during the year immediately preceding the date of the occurrence that 
is the basis for the claim or action, shall have devoted a majority of his 
professional time to:
(1) active 
clinical practice as a general practitioner; or active clinical practice that 
encompasses the medical condition, or that includes performance of the 
procedure, that is the basis of the claim or action;
(2) the 
instruction of students in an accredited medical school, health professional 
school, or accredited residency or clinical research program in the same health 
care profession in which the party against whom or on whose behalf the 
testimony is licensed; or
c. A court may waive the same specialty or subspecialty recognized by the 
American Board of Medical Specialties or the American Osteopathic Association and 
board certification requirements of this section, upon motion by the party 
seeking a waiver, if, after the moving party has demonstrated to the 
satisfaction of the court that a good faith effort has been made to identify an 
expert in the same specialty or subspecialty, the court determines that the 
expert possesses sufficient training, experience and knowledge to provide the 
testimony as a result of active involvement in, or full-time teaching of, 
medicine in the applicable area of practice or a related field of medicine.
d. Nothing in this section shall limit the power of the trial court to 
disqualify an expert witness on grounds other than the qualifications set forth 
in this section.
e. In an action alleging medical malpractice, an expert witness shall not 
testify on a contingency fee basis.
f. An individual or entity who threatens to take or takes adverse action 
against a person in retaliation for that person providing or agreeing to 
provide expert testimony, or for that person executing an affidavit pursuant to 
the provisions of P.L. 1995, c. 139 ( C. 2A:53A-26 et seq.), which adverse action 
relates to that person’s employment, accreditation, certification, 
credentialing or licensure, shall be liable to a civil penalty not to exceed $ 
10,000 and other damages incurred by the person and the party for whom the 
person was testifying as an expert.
N.J.S.A. 2A:53A-28 Affidavit 
not required; conditions 
An affidavit shall not be required pursuant to section 2 of 
this act if the plaintiff provides a sworn statement in lieu of the affidavit 
setting forth that: the defendant has failed to provide plaintiff with medical 
records or other records or information having a substantial bearing on 
preparation of the affidavit; a written request therefor along with, if 
necessary, a signed authorization by the plaintiff for release of the medical 
records or other records or information requested, has been made by certified 
mail or personal service; and at least 45 days have elapsed since the defendant 
received the request.
N.J.S.A. 2A:53A-29. Noncompliance deemed failure to state 
cause of action
If the plaintiff fails to provide an affidavit or a 
statement in lieu thereof, pursuant to section 2 or 3 of this act, it shall be 
deemed a failure to state a cause of action.
 
1. Does the Affidavit of Merit Apply to Federal 
Court Actions? Yes. New Jersey Affidavit of Merit statute, NJSA 2A:53A-26 et 
seq., applies to a medical malpractice complaints filed in the United States 
District Court of New Jersey on the ground of diversity of citizenship because 
there is no direct conflict between the New Jersey statute and Fed. R. Civ. P. 8 and Fed. R. Civ. P. 9 , the New Jersey statute 
was substantive law that was outcome determinative on its face, failure to 
apply it would encourage forum shopping and lead to the inequitable 
administration of the law, and there was no overriding federal interest that 
would have prevented application of the state law by the federal courts.  Chamberlain 
v. Giampapa , 
210 F.3d 154 (3d Cir. N.J. 2000). 
2. Who 
is entitled to the Affidavit of Merit? Only those licensed professionals 
specifically listed in the statute. 
Saunders v. Capital Health System 
at Mercer, 398 N.J. Super. 500 
(App. Div 2008).
3. What language must be included in the Affidavit? The affidavit must include the 
language that “there exists a reasonable probability that the care, skill or 
knowledge exercised or exhibited in the treatment, practice or work that is the 
subject of the complaint, fell outside acceptable professional or occupational 
standards or treatment practices”. 
See sample affidavit below.
4. Do you have to include each medical 
defendant by name? Yes, 
whenever possible. The affidavit 
should specifically identify the individual defendants who deviated from the 
standard of care whenever possible. 
Fink v. Thompson, 167 N.J. 551 (2001). While the Statute is silent as to naming 
each defendant in the affidavit (stating that the affidavit need only be served 
on each defendant) the better practice is to identify as specifically as possible 
the identity of each defendant, if not by name then by description. See Medeiros 
v. O’Donnell and Naccarato , 347 N.J. Super. 536, 542 (App. Div. 2002).
5. Time for serving Affidavit of Merit? 60 days following the answer for each 
particular defendant. This time 
limit can be extended to 120 days upon filing of a motion to extend by 
plaintiff’s attorney during the initial 60 day period. Where defense counsel files a motion to 
dismiss after the 120-day deadline and before plaintiff has forwarded the 
affidavit, the plaintiff should expect that the complaint will be dismissed 
with prejudice provided the doctrines of substantial compliance and 
extraordinary circumstances do not apply.  Ferreira v. 
Rancocas Orthopedic Assocs. , 178 N.J. 144 (2003). 
However, a delay in serving the 
Complaint on a defendant will not allow a plaintiff to thwart the time 
requirement under the statute. See Czepas v. Schenk, 362 N.J. Super. 216 (App. Div. 2003) (Patient’s counsel’s intentional 
delay in serving the summonses and complaint in order to avoid application of 
the Affidavit of Merit statute warranted dismissal of the medical malpractice 
complaint).
6. Does the “Ferreira conference” toll the 
time limit for filing the Affidavit of Merit? No. The Appellate Division most recent 
decision rejected the argument that the trial court’s failure to schedule the 
case management conference required by  Ferreira v. 
Rancocas Orthopedic Associates, 178 N.J. 144 (2003) tolled the 
time to file or otherwise excused the malpractice claimant’s failure to timely 
file an affidavit of merit.
In Paragon 
Contractors, Inc. v. Peachtree Condominium Assn., 406 N.J. Super. 568 (App. Div. 2009), the Appellate Division addressed 
the trial court’s failure to conduct a case management conference within 90 
days of the filing of the third-party defendant’s answer, as mandated by the 
Supreme Court in Ferreira v. Rancocas 
Orthopedic Associates, 178 N.J. 
144 (2003).
In this case, the plaintiff contractor sought damages from the 
defendant condominium association for unpaid fees in connection with a 
construction project. The defendant filed a third-party complaint against a 
design professional alleging that its work was incomplete and defective, but 
did not file a timely Affidavit of Merit.
In response to the design professional 
motion to dismiss, the defendant argued that the civil division manager’s 
office advised a legal assistant in its counsel’s office that a case management 
conference would be scheduled, and that the Affidavit of Merit need not be 
filed prior to the conference. The trial court rejected this argument and 
dismissed the defendant’s third-party complaint.
The Appellate Division affirmed the trial court, holding that the trial court’s 
failure to conduct the case management conference within 90 days of the filing 
of an answer does not serve to toll the time to file or otherwise excuse the 
requirement to file an Affidavit of Merit.
In rejecting the argument that the 
court’s failure to schedule the conference required by Ferreria should toll the time in 
which to file the Affidavit of Merit, the Paragon 
Court noted that the Supreme Court did not impose the early conference 
requirement “as a means of altering or amending the statute, nor, in adopting 
this innovation, did the Court reveal any intention other than to continue to 
enforce and respect the 120-day deadline crafted by the Legislature.” 406 N.J. Super. at 582. As such, the 
attorney’s failure to file the Affidavit of Merit was fatal to the professional 
negligence claim. The court 
disagreed with its earlier decision in Saunders v. Capital Health , 398 N.J. Super. 500 (App. Div. 2008), which 
allowed tolling in a similar case.
In its discussion, the court also noted that the defendant’s counsel’s failure 
was excused by neither of the equitable remedies substantial compliance or 
extraordinary circumstances available to claimants in the Affidavit of Merit 
context, as there was no indication that the defendant ever had an Affidavit of 
Merit in its possession, notwithstanding its counsel’s acknowledgment of the need 
to file one. Further, the court noted that neither attorney inadvertence nor 
counsel’s carelessness constitute extraordinary circumstances in the context of 
the Affidavit of Merit statute.
7. Does 
the Affidavit of Merit apply to informed consent cases? Yes. The Affidavit of Merit statute applies 
to a patient’s medical malpractice complaint alleging lack of informed consent 
because a plaintiff could not prevail on a lack of informed consent claim under 
New Jersey law without expert testimony that the relevant risk was recognized 
by the professional community even if an expert was not required to establish a 
standard for disclosure or to prove that a physician failed to meet the 
standard. See also, Risko v. Ciocca , 
356 N.J. Super. 406 (App. Div. 2003).
8. Does 
the expert affiant have to issue the affidavit under oath. Yes. The affidavit is not a certification and 
must be a swearing under oath. A patient’s 
malpractice suit against a doctor was properly dismissed for failure to comply 
with the Affidavit of Merit statute as the failure to place a declarant under 
oath was not a technical deficiency for which the doctrine of substantial 
compliance could be invoked, but went to the very nature of an affidavit.  Tunia v. St. 
Francis Hosp ., 363 N.J. Super. 301 ( App.Div . 
2003). 
9. Is 
the Affidavit of Merit required in common knowledge cases? No. Where defendant 
physician acknowledged misreading lab results and had misdiagnosed an ectopic 
pregnancy, performing unnecessary surgery on a non-pregnant plaintiff, 
plaintiff was not required pursuant to  N.J.S.A. 2A:53A-27 to file an 
affidavit of merit because the common knowledge exception recognized that 
meritorious claims could move forward without the added and unnecessary cost of 
hiring an expert to execute an affidavit when that expert was not going to 
testify at trial.  Palanque v. 
Lambert-Woolley , 168 N.J. 398 (2001). 
Where mother sued dentist for 
malpractice after dentist’s associate extracted the wrong tooth from child’s 
mouth, mother’s suit was improperly dismissed for failure to comply with 
affidavit of merit requirement because there was a common knowledge exception 
to the statutory requirement where expert testimony was not required to 
establish that dentist’s care fell below acceptable professional standards.  Hubbard v. 
Reed , 168 N.J. 387 (2001). 
10. Sworn Statement 
in lieu of Affidavit Based On Defendant’s Withholding Medical Records. Defendants in medical malpractice cases 
must supply all relevant and requested medical records. If not supplied, the Affidavit of Merit 
is waived upon the timely filing by plaintiff’s attorney (within 60 days—but 
120 at the latest) that the medical records were requested but not provided and 
prevented the expert from being able to produce an affidavit. See N.J.S.A. 
2A:53A-28; Aster v. Shoreline Behavioral, 
346 N.J. Super. 536 (App. Div 2002). 
However, a defendant can rebut the attorney’s sworn statement that the 
records had a “substantial bearing” on the preparation of the affidavit. For example, in Davies v. Imbesi , 328 N.J. Super. 372 (App. Div. 2000) the 
court refused to apply the waiver since the unproduced medical records applied 
to causation and not to deviation from the standard of care. Causation and proximate cause are not 
relevant to the requirements under and the preparation of the Affidavit of Merit. See also, Balthazar v. Atlantic City Medical Center, 358 N.J. Super. 13 (App. Div. 2003).
11. Will the Doctrine of Substantial Compliance 
protect a plaintiff who fails to technically comply with the statute? The Doctrine of substantial compliance 
can be invoked to avoid dismissal of a medical malpractice action with 
prejudice, but requires the moving party to show:
(1) the lack of prejudice to the 
defending party;
(2) a series of steps taken to 
comply with the statute involved;
(3) a general compliance with the 
purpose of the statute;
(4) a reasonable notice of 
petitioner’s claim; and
(5) a reasonable explanation why 
there was not strict compliance with the statute.
Galik v. Clara Maass Medical Center, 167 N.J. 341 (2001).
In Galik , 
the court found that the application of the doctrine was very fact specific and 
that the doctrine would not be applied easily. The fact that the delay was caused by 
litigation in “previously uncharted waters” was significant in the decision to 
invoke the doctrine. Id.
12. Will the 
Doctrines of Waiver/Equitable Estoppel protect a plaintiff who fails to 
technically comply with the statute? Possibly. Just as plaintiffs are required to file 
a timely affidavit under N.J.S.A. 2A:53A-27, 
defendants must also act timely and cannot sleep on their rights; thus, where a 
doctor let the deadline for receipt of an affidavit pass without filing a 
dismissal motion and where the doctor, instead, engaged in the exchange of 
interrogatories, deposed the patient and her husband and submitted to a 
deposition, obtained the patient’s expert report, and had the patient 
physically examined, the doctor’s fourteen-month delay barred his ability to 
file a motion to dismiss under the doctrines of equitable estoppel and laches.  Knorr v. Smeal , 178 N.J. 169 (2003). See also, Ferreira v. Rancocas Orthopedic Associates, 178 N.J. 144 (2003) (where the Supreme Court 
reiterated that the goal of the Affidavit of Merit statute was to “weed out 
frivolous lawsuits” and thereby applied the equitable doctrine in a case where 
the affidavit of merit had been obtained within the appropriate time but not 
supplied prior to the deadline).
In a malpractice case, a hospital was not entitled to 
dismissal of the case based on the patient’s failure to provide an Affidavit of 
Merit as required by  N.J.S.A. 2A:53A-27 because the 
hospital waited more than 20 months after it filed its answer to move for 
dismissal and the parties had already engaged in extensive discovery.  Mottola v. City of 
Union City , 2008 U.S. Dist. LEXIS 
21605 (D.N.J. Mar. 14 2008). 
13. What if the plaintiff cannot find an 
expert in the same specialty? 
A court may waive the same specialty or subspecialty recognized by the 
American Board of Medical Specialties or the American Osteopathic Association 
and board certification requirements of  N.J.S.A. 2A:53A-41 upon motion by the party seeking 
a waiver, if, after the moving party has demonstrated to the satisfaction of 
the court that:
1. A good faith effort has been made to 
identify an expert in the same specialty or subspecialty; and
2. The court determines that the 
expert possesses sufficient training, experience and knowledge to provide the 
testimony as a result of active involvement in, or full-time teaching of, 
medicine in the applicable area of practice or a related field of medicine.
The Supreme Court of New Jersey interprets that language as 
a broad grant of discretion to the trial judge that does not bear with 
it a temporal requirement that the proposed expert be engaged in performing the 
medical procedure at issue on the date of the occurrence giving rise to the 
claim.
Rather, the expert may have derived his training, experience, and 
knowledge as a result of prior practice in the field; but that is not to 
suggest that a lapse of time may not bear on a judge’s assessment of an expert’s 
training, experience, and knowledge, only that it is not an automatic 
disqualifier. The Supreme Court upheld the trial court’s use of discretion in 
allowing the waiver.  Ryan v. Renny , 203 N.J. 37 (2010) .
14. Does the Affidavit of Merit apply to a 
defendant’s third party claims? 
No. In Highland Lakes Country Club and Community 
Assoc. v. Nicastro , et al., 406 N.J. Super. 145 (App. Div. 2009), the 
court confronted the situation arising when a defendant files a third-party 
action against a licensed professional based on a plaintiff’s claim against the 
defendant. In Highland Lakes, the 
plaintiff country club sued the defendants, who were owners of an adjoining 
residential property, contending that defendants were encroaching on six acres 
of the country club’s property.
The defendants commenced a third-party action against 
their surveyor, arguing that they relied on a survey prepared by the surveyor 
prior to commencing construction. The defendants opted not to file an Affidavit 
of Merit, rationalizing that their claims for contribution, indemnification, 
and damages would not accrue unless and until the plaintiff country club 
established an error in the survey on which the defendants relied. The trial 
court denied the surveyor’s motion to dismiss.
On appeal, the Appellate Division affirmed the trial court’s decision, holding 
that the defendants were not required to file an Affidavit of Merit because 
their third-party claims against the surveyor were not yet ripe. The court’s 
rationale was that the Affidavit of Merit Statute’s goal of preventing 
frivolous claims against professionals from proceeding was not implicated by 
third-party claims that are asserted to protect against possible liability 
based on the negligence of the professional.
As the defendants had not asserted 
that the survey was inaccurate or that they had been damaged by errors in the 
survey, the court found that, as a practical matter, application of the Statute 
was not necessary to preclude the defendants’ claims because they would only 
pursue those claims when and if the plaintiff provided evidence of an error in 
the survey to support its claim against the defendants. The court was also persuaded by the 
unfairness to the defendants that would result if they were required to file an 
Affidavit of Merit at this stage, stating that the Affidavit of Merit requirement 
was not intended to “eliminate claims not yet ripe for adjudication without 
regard to merit when assertion of probable merit would require a defendant to 
support the claims asserted against it by a plaintiff who has not come forward 
with competent proof of the error it alleges.” 406 N.J. Super. at 154-155.
The court suggested, however, that once the 
plaintiff provides evidence of an error in the survey, the defendants’ claim 
for professional negligence accrues, which would likely trigger the 120-day 
clock for filing an Affidavit of Merit.
The New Jersey Supreme Court recently affirmed the Appellate Division decision 
in a short per curiam opinion. Highland Lakes Country Club & Cmty . Ass’n v. Nicastro , 201 N.J. 123 (2009). In doing so, the Court noted that its 
affirmance was based on “substantially . . . the reasons expressed in the 
thorough and thoughtful opinion” of the Appellate Division.
15. Recent confusion concerning experts and 
qualifications to render the Affidavit of Merit:
In Harbeson v. 
Underwood Memorial Hospital , 2009 N.J. Super. Unpublished LEXIS 1676 (App. Div.), the Appellate Division held 
that an affidavit was required to be filed against a nurse anesthetist even 
though that profession is not specifically designated by N.J.S.A. 2A:53A-26. 
In Harbeson , the plaintiffs 
alleged that a nurse anesthetist improperly delayed the administration of a 
pre-operative antibiotic. The Harbeson Court utilized the definition of a 
“health care provider” in N.J.S.A. 
2A:53A 40(e) rather than those is 2A:53A-26 stating:
The Medical Care Act did not define “medical 
malpractice action.” However, one of the significant changes it made to 
the State’s tort liability system was to provide an “affidavit of 
noninvolvement” as a means to secure the dismissal of a 
medical-malpractice action. N.J.S.A. 
2A:53A-40. Specifically, “[a] health care provider named as a defendant in 
a medical malpractice action may cause the action against that provider to be 
dismissed upon the filing of an affidavit of noninvolvement with the 
court.” N.J.S.A. 2A:53A-40(a). 
It further defined “health care provider” as:
an individual or entity which, acting within the 
scope of its licensure or certification, provides health care services, and 
includes, but is not limited to: a physician, dentist, nurse, pharmacist or 
other health care professional whose professional practice is regulated 
pursuant to Title 45 of the Revised Statutes; and a health care facility 
licensed pursuant to P.L. 1971, c. 136 (C. 26:2H-1 et seq.).
Thus, a medical-malpractice action is an action 
against a licensed individual providing health care services as specified in N.J.S.A. 2A:53A-40(e). Consequently, an 
affiant on an affi_davit of merit in an action against a health-care provider, 
as defined by N.J.S.A. 2A:53A-40(e), 
must meet the requirements of N.J.S.A. 
2A:53A-41.
The 
court then declared that a nurse-anesthetist is a “general practitioner” and that 
same Board certification was not required. 
The court held that the expert must meet the criteria of N.J.S.A. 43A 41(b), and remanded the case back to the trial 
judge to make more specific findings regarding whether the experts met those 
practice qualifications.
In Buck v. Henry, 203 N.J. 432 (2011) Supreme Court 
reversed an Appellate Division dismissal of a medical malpractice action for 
the plaintiff’s failure to comply with the Affidavit of Merit requirement of 
having like qualified experts where the plaintiff sued a family practitioner but 
obtained affidavits from a psychiatrist and an emergency medicine doctor.
The facts were such that the plaintiff, a depressed insomniac, 
consulted the defendant, who was board certified in emergency medicine but was 
practicing family medicine. The defendant prescribed Zoloft to improve the 
plaintiff’s mood and Ambien to help him sleep. The plaintiff took the Ambien 
and fell asleep while he was “inspecting his .38 caliber Colt revolver. 
Thereafter, plaintiff was awakened by what he thought was the sound of a 
telephone ringing. Forgetting that the handgun was still in his right hand, he 
reached for the telephone with his left hand. According to plaintiff, this 
action caused the barrel of the handgun to enter his mouth and discharge.”
The plaintiff served two Affidavits of Merit, one from a board-certified 
psychiatrist and another form a physician board certified in emergency 
medicine. The defendant moved to dismiss because neither affiant practiced 
family medicine.
The Appellate Court agreed, holding:
[W]e accept Dr. Henry’s certification that he is a family medicine 
specialist because he has devoted his medical practice to that rec_ognized 
specialty area . . . Because plaintiff was required to submit an affidavit of 
merit from a physician who specialized in family medicine, and he failed to do 
so, the motion judge correctly granted Dr. Henry’s motion to dismiss his 
complaint.
The 
Supreme Court reversed and remanded for a case management conference finding 
that enough confusion existed regarding the defendant’s specialty to excuse 
plaintiff’s mistake. The confusion 
stemmed from the failure of the trial court to hold a Ferreira conference 
coupled with the fact that the defendant physician was board certified in 
emergency medicine and was providing psychological treatment that shows 
plaintiff’s efforts were in good faith. 
Thus, the two affidavits, although subsequently determined to be 
incorrect, were obtained in good faith and show that plaintiff did not sleep on 
his rights but was justifiably confused regarding which specialty the defendant 
was practicing when he administered the care that was the subject of the 
suit. Going forward, the Supreme 
Court has requested that the Rules Committee require a defendant to disclose 
the specialty he was practicing at the time of the treatment to avoid any future 
problems.
It 
is therefore prudent to obtain an Affidavit from an expert who is board 
certified in the same area as the defendant and, if the defendant is practicing 
out of his field, a second Affidavit from an expert who actively treats the 
condition or performs the procedure in question.
In  Ryan v. Renny , 203 N.J. 37 (2010) , a case arising out of the performance of a colonoscopy by a 
gastroenterologist, the Supreme Court upheld the trial court’s determination 
granting a plaintiff’s application for waiver of the same 
specialty/qualification and in so doing allowed a surgeon who was not board 
certified in gastroenterology and who had not performed a colonoscopy in years qualified 
to render the Affidavit of Merit. The plaintiff’s attorney certified that he 
had contacted three gas_troenterologists who would not review the case. The 
plaintiff’s attorney then secured the services of a general surgeon who had 
substantial experience with colon surgery and who had performed colonoscopies, 
albeit long ago.
Justice Long writing for the Supreme Court set 
forth the standard that a plaintiff must demonstrate to invoke the waiver but 
also gave the trial court broad discretion in reviewing the application with no 
one factor being determinative. The 
key language was as follows:
[T]he plain 
language of the waiver provision, which directs the judge to focus on the 
“effort” the moving party made to obtain a statutorily-authorized 
expert, and not on the reasons why a particular expert or experts declined to 
execute an affidavit. That focus reflects a legislative judgment that the 
moving party should make a legitimate attempt to obtain an 
equivalently-qualified expert and should not be relieved of that burden by 
desultory undertakings or half-hearted endeavors. It follows that, to prove a good faith 
effort, a moving party must show what steps he undertook to obtain an expert 
qualified according to  N.J.S.A . 2A:53A-41(a) 
or (b) .
By way of example, that would include: 
the number of experts in the field; the number of experts the moving party 
contacted; whether and where he expanded his search geographically when his 
efforts were stymied; the persons or organizations to whom he resorted for help 
in obtaining an appropriate expert; and any case-specific roadblocks (such as 
the absence of local sub-specialty experts) he encountered. However, the 
experts’ reasons for declining simply do not bear on the robustness of movant’s 
efforts.
Indeed, the very existence of the waiver provision makes 
it obvious to us that the Legislature did not intend a malpractice case to 
stand or fall solely on the presence or absence of a same-specialty expert. However, if that were the case, the Legislature 
would not have provided for waiver or, at the very least, would have declared 
that waiver was somehow limited by the substance of an expert’s refusal to 
execute an affidavit. It did not do 
so.
By the broad waiver provision, the Legislature explicitly recognized that there 
would be legitimate malpractice claims for which a plaintiff would not be able 
to obtain an affidavit of merit from an equivalently-qualified expert or even 
from an expert in the same field. Thus, it created a safety valve for those 
cases by providing the judge with broad discretion to accept an expert with 
“sufficient training, experience and knowledge to provide the testimony”, 
but only if plaintiff made a good faith effort to satisfy the statute. Moreover, the 
Legislature left it to the “satisfaction of the court” to determine 
whether an honest “effort” was made to identify an expert in the same 
specialty or subspecialty. Hence, it is the “effort” of the movant that is the 
focal point of the waiver provision.
16. Affidavit 
of Merit – Must still be obtained against the negligent professional even where 
the public entity is the only defendant sued. McCormick v. State, 446 N.J. 
Super. 603 (App. Div. 2016). 
Same is true if plaintiff sues only a professional corporation and not 
the professional. Shamrock 
Lacrosse, Inc., v. Klehr , Haririson , 
Harvey, Branzburg & Ellers , 
LLP, 416 N.J. Super. 1 (App. Div. 2010).
17. Specialists- Only Doctors are specialists under the 
AOM statute. The specialization 
requirement of section 41 of the PFA only apply to physicians (NOT applicable 
to nurses, lawyers, dentists etc.). 
Meehan v. Antonellis , 226 N.J. 
216 (2016). For other professionals 
who are not doctors, the expertise requirement can overlap more easily and need 
not be identical to that of defendant to TESTIFY or offer AOM.
