Paternity Establishment in California

In California, establishing legal paternity is more than just paperwork—it’s a foundational step in securing the legal, emotional, and financial rights of both the child and the parents. Whether you’re a mother seeking child support or a father wanting to build a relationship with your child, confirming paternity creates clarity, accountability, and opportunity.

What Is Paternity—and Why Does It Matter?

Paternity means legally identifying the child’s biological father. In California, when a child is born to unmarried parents, paternity is not automatically established. Until it is, the biological father has no legal rights or responsibilities, no right to custody or visitation, and no obligation to provide support.

Establishing paternity ensures:

• The child can receive financial support from both parents

• Either parent can seek custody or visitation

• The child gains access to health insurance, inheritance rights, and benefits like Social Security or veterans’ assistance

• Both sides of the child’s medical history are documented

• Emotional connection and parental identity are supported from the beginning

Legal and Financial Implications of Paternity in California

Without legal paternity, a father:

• Cannot be ordered to pay child support

• Cannot petition for custody or visitation rights

• Will not be listed on the child’s birth certificate

Once paternity is established:

• The court can make custody, support, and visitation orders

• The father’s name is added to the birth certificate

• Financial obligations—and rights—become enforceable under California law

For mothers, paternity provides access to court-ordered support. For fathers, it creates a legal path to active parenting. For children, it unlocks benefits, identity, and stability.

How to Establish Paternity in California

There are two main ways to establish paternity:

1. Voluntary Declaration of Parentage (VDOP) - This form is often signed at the hospital after the child is born but can also be completed later at a local child support agency, family law facilitator’s office, or through the California Department of Child Support Services (DCSS). Once filed with DCSS, it has the same legal effect as a court judgment.

2. Court-Ordered Paternity Action - If either party disputes paternity or declines to sign the VDOP, a court case may be opened. The court can order genetic testing. These actions can be initiated by either parent or by DCSS if public assistance is involved.

After paternity is established, the court can issue legally binding orders regarding child support, custody, and visitation.

Why Timing Matters: Establish Early, Avoid Complications

Delaying the establishment of paternity can lead to unnecessary stress, legal hurdles, and financial uncertainty. Early action helps:

• Fathers secure parental rights and begin meaningful relationships from the start

• Mothers ensure support is legally available and enforceable

• Children gain access to identity, benefits, and support from both parents

Establishing paternity early also helps prevent future disputes and ensures that decisions affecting the child are made with legal clarity.
