Who should worry about establishing parentage?
You may need to address parentage issues if:
- You are an unmarried parent: When a child is born to unmarried parents, the father isn’t automatically recognized as the legal father unless the father takes steps to become a legal parent (like signing an acknowledgment of parentage form).
- You are unsure about your child’s biological father: Parentage cases can help you sort out who is a child's biological parent.
- You want legal rights as a father: Establishing parentage ensures you have legal rights and responsibilities. It allows you to go to court and ask for custody or visitation rights.
- You want financial support for your child: You must establish parentage to get financial support from the other parent.
How to establish parentage in Oregon
There are three main ways to establish parentage in Oregon:
- Sign official paperwork: Both parents can sign a "Voluntary Acknowledgment of Paternity" form. This form is usually completed at the hospital after the child is born, but it can also be done later. The signed form must be filed with the Oregon Center for Health Statistics. You can download Oregon's "Voluntary Acknowledgement of Paternity Affidavit" here.
- Agency process: The Oregon Child Support Program (CSP) can help parents establish parentage for free. This process may include genetic (DNA) testing if parentage is in question. Parents don't have to ask for child support to use the CSP's parentage services. Once parentage is established, a legal order is issued. Learn more about parentage establishment services on the CSP website.
- Court order: Either parent can go to court to establish parentage. The court may order genetic testing to sort out who the biological father is. The court then issues legal paperwork that states who the child's legal father is. However, this is a complicated process and you should consider hiring a lawyer to help you.
Why is establishing parentage important?
Establishing parentage benefits children and parents:
- Children: Establishing parentage gives children access to financial support from both their parents. It also grants children access to their father's health insurance, Social Security benefits, and inheritance. It can also foster a stronger sense of identity and family connections.
- Fathers: Establishing parentage provides fathers with an opportunity to build a relationship with their child. A legal father can also go to court and ask for custody or parenting time orders so they can see their child regularly.
- Mothers: Establishing parentage allows mothers to ask for child support so they can get help raising their children.
