A Pennsylvania Custody Petition is a legal document used to request either physical or legal custody of a child in the state of Pennsylvania. Physical custody refers to the parent who is responsible for the physical care of the child, while legal custody refers to the parent who has the authority to make decisions regarding the child’s welfare. There are two types of Pennsylvania Custody Petition: a Petition for Custody and a Petition for Partial Custody. The Petition for Custody is used when one parent is requesting full physical and legal custody of the child, while the Petition for Partial Custody is used when one parent is requesting partial physical and legal custody of the child. Both types of petitions require detailed information regarding the child's current living situation, and the parent's past and current involvement in the child’s life. The petition must be filed in the Court of Common Pleas in the county where the child resides.
