A New Jersey Dependency Claim Petition is a legal document that can be used by a parent or guardian to seek financial support from the non-custodial parent of a minor child. The petition is filed in the county in which the child lives and is used to establish paternity, establish a child support obligation, or modify an existing support order. In New Jersey, there are two types of dependency claim petitions: the Dependency Complaint and the Dependency Modification Complaint. The Dependency Complaint is used to establish paternity and/or to set a child support obligation. The Dependency Modification Complaint is used to modify an existing support order.
