Pennsylvania Certification Regarding Domestic Support Obligation(s) is a form issued by the Pennsylvania Department of Human Services, Office of Child Support Enforcement. It is used to certify the amount of domestic support obligation that is due and unpaid. This certification is required for any party seeking to collect on unpaid child support payments in the state of Pennsylvania. It also serves as proof of the amount of unpaid child support payments and the failure to pay them on time. Pennsylvania Certification Regarding Domestic Support Obligation(s) is available in two forms: an Annual Certification and a Temporary Certification. The Annual Certification is issued annually and includes information such as the name of the person obligated to pay, the total amount of unpaid child support, and the amount of interest due. The Temporary Certification is issued when a request for a modification of the child support order is made. It includes the same information as the Annual Certification, but only applies to the requested modification.
