Establishing a guardianship is a formal, public, legal process. It is initiated when someone files a petition with a Maryland circuit court to be appointed guardian for an “alleged disabled person.” It should be noted that a disabled person is always an “alleged” disabled person until that person is determined by a court to be disabled, based on competent medical evidence, affidavits or opinions. Prior to that determination, a person is presumed to have capacity. If the court determines that a person is disabled, the court will appoint someone, most often an interested person, to serve as guardian, and issue an order setting out the terms and conditions of the appointment.
