Medical Malpractice Pre-Suit Requirements

United States (federal and general)Last reviewed 18 September 2026

Many states impose special steps before or soon after filing a malpractice suit: a notice of intent, a pre-suit investigation, and a qualified expert's report or affidavit of merit. Missing a step can get a case dismissed regardless of its merits, so the rules of your state matter as much as the facts.

Expert Reports and Affidavits of Merit

Direct Answer: Most states require a qualified medical expert to support the claim, and many require a report or affidavit at the start of the case to screen out weak claims.

For example, Texas law requires a claimant to serve an expert report on each defendant physician or health care provider within 120 days after that defendant's original answer is filed, or the claim faces dismissal. Other states require a certificate or affidavit of merit when the complaint is filed. The precise content and timing differ by state, and must be met exactly.

Notice of Intent and Waiting Periods

Florida requires a notice of intent to initiate litigation and a presuit investigation period before a medical negligence suit can be filed, with a defined waiting time for the provider's response. Several other states have comparable notice requirements, and some use screening panels.

Damage Caps and Repose

Some states cap non-economic damages in malpractice cases, for example Texas under Chapter 74 and California under its medical malpractice statute, and New York regulates malpractice attorney fees by a sliding scale under Judiciary Law § 474-a. Many states also have a statute of repose that sets an outer deadline regardless of when you discovered the injury. Check your state's rules and the state pages on this site.

Frequently Asked Questions

What is an affidavit of merit?

A statement from a qualified medical expert that the claim has merit, required at or soon after filing in many states. It screens out weak claims and must meet the state's requirements.

Do I have to give notice before suing a doctor?

In some states, yes. Florida, for example, requires a notice of intent and a presuit investigation period. Check your state's requirements.

Are there caps on malpractice damages?

Some states cap non-economic damages, and the size and scope differ by state. Texas and California, for example, have statutory limits, and a few states have struck caps down.

What is a statute of repose?

An outer time limit that bars a claim after a set number of years from the negligent act, even if you had not yet discovered the injury.

Are attorney fees limited in malpractice cases?

In some states, yes. New York, for example, uses a sliding scale under Judiciary Law § 474-a, and other states have statutory limits or court approval requirements.

How long do I have to file a medical malpractice claim?

It depends on the state, and is often two to three years from the injury or from when you discovered or should have discovered it, with an outer statute of repose in many states. Claims against government hospitals and federal facilities such as VA centers have separate, shorter notice requirements, so contact an attorney as soon as you suspect malpractice.
