Whenever a guardian or limited guardian who has been appointed for an incapacitated or partially incapacitated person has been discharged by the final order of a court having jurisdiction thereof, and no other guardian has been appointed for said person by a court of competent jurisdiction, the person for whom said guardian had been appointed shall be presumed to be fully restored and shall be presumed to be fully capable and competent to make contracts and transact any and all business as though said person had never been declared to be incapacitated or partially incapacitated.
