After a person's incapacity has been determined judicially upon application for the appointment of a guardian, a person of unsound mind can make no conveyance or other contract, nor delegate any power, nor waive any right until the person's restoration to capacity is determined judicially. If actually restored to capacity, the person may make a will, though the person's restoration is not determined judicially.
