The Agency can try to find absent parents by using the State Parent Locator Service if you provide the parent's name and social security number. If the absent parent has moved to another state, the Agency can ask the other state to find him/her. The Agency can also search throughout the United States for the absent parent by using the Federal Parent Locator Service.
A court hearing cannot be held to establish or enforce support unless the absent parent has been properly served with a notice of the hearing.
