How Massachusetts courts treat expert testimony
The rules every expert must meet in Massachusetts, medical or not.
Daubert-Lanigan
Massachusetts adopted Daubert reliability analysis in Commonwealth v. Lanigan, 419 Mass. 15 (1994). General acceptance remains a strong indicator of reliability, and the standard is codified in Mass. G. Evid. § 702.
The Trial Court’s Superior Court handles major civil and criminal trials; the District Court and Boston Municipal Court handle lesser matters. The intermediate appellate court is the Appeals Court, and the highest court is the Supreme Judicial Court.

Massachusetts medical expert requirements
What a medical expert must satisfy before testifying in a Massachusetts malpractice case.
Who qualifies as a medical expert
No statute requires the same specialty or recent practice. Under Letch v. Daniels, 401 Mass. 65 (1987), the expert needs enough education, training, experience and familiarity with the subject, and a difference in specialty goes to weight, not admissibility.
Certificate, affidavit or presuit requirement
There is no affidavit of merit. The plaintiff must give 182 days’ written presuit notice (G.L. c. 231, § 60L). After the answer, a malpractice tribunal reviews the plaintiff’s offer of proof, usually an expert letter, under § 60B and Superior Court Rule 73. After an adverse finding, the plaintiff can proceed only by posting a $6,000 bond.
Out-of-state experts
No Massachusetts license or registration is required for retained experts. The licensure requirement in § 60B applies only to the physician member of the tribunal.
Statute of limitations
Three years from accrual under the discovery rule, with a 7-year repose except for foreign objects (G.L. c. 260, § 4). Children under 6 have until their 9th birthday (c. 231, § 60D).
Damage caps
General damages such as pain and suffering are capped at $500,000 (G.L. c. 231, § 60H). The cap does not apply if there is substantial or permanent loss or impairment of a bodily function, substantial disfigurement, or other special circumstances. Economic damages are not capped.
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.
Defense and prosecution experts in Massachusetts
An indigent defendant can move for extra fees and costs, including expert services, under the Indigent Court Costs Law, G.L. c. 261, §§ 27A–27G. The court must grant a request that is reasonably necessary to give the defendant as effective a defense as one who could pay (§ 27C(4); Commonwealth v. Davis, 410 Mass. 680 (1991)).
We place experts in homicide, abusive head trauma (shaken baby), child abuse and non-accidental trauma, competency and criminal responsibility, and vehicular cases.

Questions attorneys ask about Massachusetts experts
What expert admissibility standard does Massachusetts use?
The Daubert-Lanigan standard (Commonwealth v. Lanigan, 1994), codified in Mass. G. Evid. § 702. Judges test reliability, and general acceptance is a key but not the only factor.
Does Massachusetts require the medical expert to share the defendant’s specialty?
No. Under Letch v. Daniels (1987), a specialty difference affects weight, not admissibility. The question is the expert’s familiarity with the applicable standard of care.
Does the expert have to appear at the Massachusetts medical malpractice tribunal?
No. G.L. c. 231, § 60B allows the offer of proof to rely on written expert statements without the expert appearing.
How does an indigent criminal defendant in Massachusetts pay for an expert?
By a motion for extra fees and costs under G.L. c. 261, § 27C. The judge must grant it if the expert is reasonably necessary to an effective defense.
