How is Paternity Established?

The paternity of a child born to non-married parents can be established one of two ways: judicially through the entry of a court order or administratively with the filing of a paternity acknowledgement form. Establishing paternity creates a legal relationship between a parent and child.

The Department of Health and Social Services (DSHS), Division of Child Support (DCS), Family Support Division establishes paternity judicially through the entry of a court order in Jefferson County Superior Court. Judicial paternity actions address the following:

  • Paternity;
  • Child support;
  • Back support;
  • Health insurance for the child; and
  • Custody of the child.

A parenting plan or residential schedule can also be requested in the context of a parentage action; however, it is not required and the State of Washington is not authorized to take a position on parenting plan issues.

The same legal remedies are available with an administrative establishment of parentage (paternity acknowledgement form), however neither a parenting plan or a residential schedule can be entered in an administrative action.

To request services related to the establishment of paternity please contact DCS.
