Guardianship for Adults

A Guardian is a person who is given Probate Court authority to be responsible for the personal and physical well being of an adult who is called a Legally Incapacitated Individual (LII). The Guardian has the same powers and duties over that LII as parents have over their children. A prospective Guardian may be nominated by petition (filed with the Probate Court) or may be named in a will.
