Parentage can be established at a hearing with the Department of Healthcare and Family Services (DHFS) instead of a judge. It is easier than going to court, but it can take a long time. Also, it only deals with parentage and child support.  Parenting time and parental responsibilities will not be decided.

Apply

To start the process, contact the DHFS Division of Child Support Services (DCSS) at 1-800-447-4278 (TTY: 1-800-526-5812) or get the application online.

Get the test

With the mother, sign an agreement to be bound by the results of genetic testing. DCSS will provide the test. If they find you are a parent, they will enter an Administrative Parentage Order and tell the Vital Records Unit to add your name to the child's birth certificate. This means that legal parentage is established.
