My question involves guardianship in the State of Pennsylvania. An elderly woman has cared for her handicapped daughter for over 50 years (since the daughter's birth). No legal guardianship was ever established. In the event of the death of the now elderly mother, will the remaining family members (i.e., siblings of the handicapped daughter) have any rights to continue caring for and managing the affairs of their handicapped sibling? Is it necessary for the elderly mother to procure legal guardianship to ensure care of the handicapped daughter remains within the family?
