A Pennsylvania Complaint for Support is a legal document filed in court to ask for support from the non-custodial parent or other party responsible for providing financial support to a dependent child. This court document is used to establish, modify, or enforce a child support agreement. It is typically filed by a custodial parent or other guardian of the child. There are two types of Pennsylvania Complaint for Support: an initial complaint and a modification complaint. An initial complaint is used to establish a court order for child support when the child’s parents are not married or were never married. A modification complaint is used to modify an existing court order for child support. This type of complaint can be used to increase, decrease, or terminate child support.
