Minnesota Medical Malpractice Laws

Minnesota medical malpractice claims are subject to a shorter statute of limitations than general personal injury (4 years vs. 6 years). The state does not cap compensatory damages in medical malpractice cases, but does require an affidavit of expert review before filing suit. Minnesota follows the same comparative fault rules as other personal injury cases.
