How Maryland courts treat expert testimony
The rules every expert must meet in Maryland, medical or not.
Daubert
In Rochkind v. Stevenson, 471 Md. 1 (2020), Maryland’s highest court adopted Daubert and abandoned the Frye-Reed general-acceptance test. Admissibility of all expert testimony is now governed by Md. Rule 5-702 as read through the Daubert factors.
Circuit courts are the general-jurisdiction trial courts, and the District Court of Maryland handles limited-jurisdiction matters. Appeals go to the Appellate Court of Maryland, and the highest court is the Supreme Court of Maryland (both renamed in December 2022).

Maryland medical expert requirements
What a medical expert must satisfy before testifying in a Maryland malpractice case.
Who qualifies as a medical expert
Within five years of the alleged act, the expert must have had clinical experience, provided clinical consultation, or taught in the defendant’s specialty or a related field (Cts. & Jud. Proc. § 3-2A-02(c)(2)(i)). If the defendant is board certified, the expert must be certified in the same or a related specialty, with limited exceptions. The expert also cannot have spent more than 25% of professional activities on personal-injury testimony (§ 3-2A-04(b)(4)).
Certificate, affidavit or presuit requirement
Claims are first filed with the Health Care Alternative Dispute Resolution Office (HCADRO). Within 90 days, the claimant must file a certificate of qualified expert with the expert’s report attached (§ 3-2A-04(b)), or the claim is dismissed without prejudice. Most parties then waive arbitration and proceed to circuit court.
Out-of-state experts
No Maryland license, registration or fee is required. The statutory tests turn on specialty experience, board certification and the 25% testimony rule, not on where the expert is licensed.
Statute of limitations
Suit must be filed by the earlier of five years from the injury or three years from discovery (Cts. & Jud. Proc. § 5-109). Claims by young minors run from age 11, or age 16 for certain injuries. Filing with HCADRO counts as filing the action.
Damage caps
Noneconomic damages are capped at $650,000 plus $15,000 for each year since 2009. For causes of action arising in 2026 that is $920,000, and 125% of that ($1,150,000) for wrongful death with two or more beneficiaries (§ 3-2A-09). 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 Maryland
Indigent defendants generally obtain experts through the Office of the Public Defender, which must provide representation and related necessary services and facilities (Md. Code, Crim. Proc. § 16-201), with Ake v. Oklahoma as the constitutional floor. Moore v. State (Md. Ct. Spec. App. 2004) held that a defendant who retains private counsel generally cannot obtain state-funded expert services separately.
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 Maryland experts
What is Maryland’s 25% rule for expert witnesses?
An expert who signs a certificate or testifies in a malpractice case cannot have spent more than 25% of professional activities on personal-injury testimony in the 12 months before the claim was filed (Cts. & Jud. Proc. § 3-2A-04(b)(4)).
Is Maryland a Daubert or Frye state?
Daubert. Rochkind v. Stevenson (2020) replaced the Frye-Reed test, and Md. Rule 5-702 now applies to all experts.
When is the Maryland certificate of qualified expert due?
Within 90 days after the claim is filed with HCADRO, with the expert’s report attached (§ 3-2A-04(b)). One extension of up to 90 days is available in limited circumstances.
What is Maryland’s medical malpractice damages cap in 2026?
$920,000 in noneconomic damages for causes of action arising in 2026, or $1,150,000 in wrongful-death cases with two or more beneficiaries (§ 3-2A-09). Economic damages are not capped.
