What you need is a Petition for Guardianship. Your father would have to have obtained a guardianship at some time in the past in order to have ?custody? of your sister. If so, you need to apply for an amendment of the original guardianship in that same court in order to become the new guardian. Check around in your area to see if there are any attorneys doing pro bono (no fee) consultations on these matters. Also, the court may have some persons whose job it is to help folks with these kinds of issues.
