How New Jersey courts treat expert testimony
The rules every expert must meet in New Jersey, medical or not.
Daubert (state variant)
In re Accutane Litigation, 234 N.J. 340 (2018) adopted Daubert-style reliability factors under N.J.R.E. 702 for civil cases. State v. Olenowski, 255 N.J. 529 (2023) extended the same standard to criminal and other cases, replacing Frye.
The Superior Court is the trial court (Law Division and Chancery Division, organized into 15 vicinages). Appeals go to the Superior Court’s Appellate Division, and the highest court is the Supreme Court of New Jersey.
- U.S. District Court, District of New Jersey
New Jersey medical expert requirements
What a medical expert must satisfy before testifying in a New Jersey malpractice case.
Who qualifies as a medical expert
The Patients First Act, N.J.S.A. 2A:53A-41, requires the expert to be in the same ABMS/AOA specialty or subspecialty as the defendant, and board certified if the defendant is. The expert must also have spent a majority of professional time in the year before the occurrence in clinical practice or accredited teaching in that specialty. Courts apply it strictly (Nicholas v. Mynster, 213 N.J. 463 (2013)). For a defendant certified in several specialties, an expert in any one relevant specialty is enough (Wiggins v. Hackensack Meridian Health (2025)).
Certificate, affidavit or presuit requirement
The plaintiff must serve an affidavit of merit from an appropriate licensed person within 60 days after the defendant’s answer. The court can grant one 60-day extension for good cause (N.J.S.A. 2A:53A-27). Missing the deadline is treated as failure to state a claim (2A:53A-29).
Out-of-state experts
No New Jersey license or registration is needed. A medical expert only needs a professional license in the United States (2A:53A-41), and no expert may testify on a contingency fee.
Statute of limitations
Two years from accrual under the discovery rule (N.J.S.A. 2A:14-2). A minor’s birth-injury claim must be filed before the child’s 13th birthday. There is no statute of repose for medical malpractice.
Damage caps
No cap on compensatory damages. Punitive damages are capped at the greater of five times compensatory damages or $350,000 (N.J.S.A. 2A:15-5.14).
Case & Record Review
Thorough review of records, imaging, reports and evidence.
Written Opinions
Clear, defensible expert reports and affidavits.
Deposition Testimony
Prepared, credible testimony under examination.
Trial Testimony
Plain-language explanation for judge and jury.

Questions attorneys ask about New Jersey experts
Is New Jersey a Daubert state?
Effectively yes. Accutane (2018) brought Daubert factors into civil cases, and State v. Olenowski (2023) applied them to criminal cases, ending Frye in New Jersey.
When is the affidavit of merit due in New Jersey?
Within 60 days after the defendant files an answer, with one 60-day extension possible for good cause (N.J.S.A. 2A:53A-27). A late affidavit generally means dismissal with prejudice.
Can an expert licensed in another state sign a New Jersey affidavit of merit?
Yes. N.J.S.A. 2A:53A-41 accepts a license from anywhere in the United States, but a medical expert must still meet the same-specialty and majority-of-time tests.
Can a privately retained defendant who runs out of money get a court-funded expert in New Jersey?
Yes, if found indigent. Under In re Cannady (1991), the Office of the Public Defender may pay for necessary expert services even though the defendant has private counsel.
Can Expert Witness Networks provide an expert for a New Jersey case?
Yes. Our experts travel and testify in New Jersey state and federal courts for plaintiff and defense counsel, prosecutors, pro se parties and private individuals. You receive the expert’s CV and fee schedule before anything proceeds.
