How to Establish Paternity in California: Legal Process, Child Support & Rights
Why Establishing Paternity Is Essential in California
Establishing paternity in California is a vital legal step to secure a child’s rights, financial support, and strong parental bonds. You can establish paternity through voluntary declarations (VDOP), court orders, or genetic DNA testing. Understanding the process helps families navigate legal parentage, custody, visitation, and child support.
What Is Legal Parentage in California?
Legal parentage means a biological or adoptive parent is recognized as a child’s legal guardian. For unmarried parents, establishing parentage secures custody, visitation, and financial support. Learn more from California Courts.
How to Establish Paternity in California
1. Voluntary Declaration of Paternity (VDOP)
Parents can sign a Voluntary Declaration of Paternity form at the hospital or through their local child support agency. The VDOP legally establishes paternity and adds the father’s name to the birth certificate—no court case required.
2. Genetic DNA Testing
If parentage is disputed or uncertain, court-admissible DNA testing provides over 99% accurate scientific proof.
3. Court Order for Paternity
If there’s disagreement or a parent refuses to cooperate, either party may petition the court. The court can order DNA testing and issue a binding judgment, establishing legal parentage and support obligations.
