In Michigan, generally you must file a lawsuit within two years of the date of the malpractice. If the negligent act is discovered after the two year period, you may have an additional six months to file your Michigan medical malpractice lawsuit under the “discovery rule.” Additionally, in medical malpractice cases involving minors or legally incapacitated persons, the limitations periods are often longer. If you miss a deadline, your claim will be lost forever. Before a medical malpractice lawsuit can even be filed in Michigan, a patient must send a “Notice of Intent To File Suit” to all possible negligent parties six months before a lawsuit can even be filed with the court. The failure to serve this letter on the proper parties may prevent the filing of a lawsuit.
