Guardianships are legal actions filed in court. A petition will have to be filed in the circuit court alleging that the named person (18 years or older) needs a guardian and that a named individual or agency be appointed. A signed report by a physician (within 90 days of filing) is required along with the petition. The report must specify the diagnosis and prognosis of the patient as well as a recommendation whether a guardian is necessary, and if so, the extent and scope of guardianship. There are court costs and it is recommended contacting an attorney for assistance.
