Understanding Paternity in California: What You Need to Know

Establishing Paternity is More Than Just Signing a Birth Certificate
Did you know that in California, a father signing an Acknowledgment of Paternity form at the hospital or having his name placed on a child’s birth certificate does not necessarily establish legal paternity? While these documents serve as evidence of paternity, they do not automatically grant full parental rights or responsibilities—except in specific legal circumstances.
To secure parental rights, a court order is often required to establish legal parentage and ensure both parents’ rights and responsibilities are legally recognized.
Why is Establishing Paternity Important?
When an unmarried couple has a child, each parent’s legal rights can be severely limited until the court formally establishes parentage. A paternity lawsuit is typically filed by either parent to determine:
- Custody and Visitation Rights
- Child Support Obligations
- Legal Rights as a Parent
Without a court order, one or both parents—especially the child’s father—may face challenges in enforcing their rights regarding the child’s upbringing, custody, and financial support.
Who Can File a Paternity Lawsuit?
Either parent can file a paternity lawsuit to resolve issues related to custody, visitation, and child support. Additionally, the Department of Child Support Services may initiate legal action on behalf of one parent, usually to establish child support orders.
Once a Judgment of Parentage is issued, the court can officially determine:
- The legal identity of both parents
- Custody and parenting plan orders
- Child support obligations
What If You’ve Been Served With a Paternity Lawsuit?
If you receive legal papers regarding parentage, you must respond within a limited timeframe—typically 30 days in California. Failure to respond could result in the other parent obtaining court orders by default, leaving you with no say in custody, support, or visitation arrangements.
While the case is pending, either parent may request temporary court orders regarding custody, visitation, and child support. Once parentage is legally established, these orders may become final or subject to modification as circumstances change.
