Establishing Paternity: The First Step for Unmarried Parents in Crisis

When a child is born to unmarried parents in California, the law does not automatically recognize the father. That absence of legal recognition can create real consequences for everyone involved, including the child. Establishing paternity is often the first and most urgent step a family needs to take, and understanding how that process works in California can make a difficult situation feel far more manageable.

What Is Paternity and Why Does It Matter?

Paternity is the legal establishment of a child’s father. Without it, an unmarried father has no enforceable parental rights in California.

Until paternity is established, an unmarried father cannot seek custody or visitation through the courts. The child, in turn, may not have access to the father’s health insurance, Social Security benefits, veterans’ benefits, or the right to inherit. These are not minor inconveniences; they are gaps in a child’s legal foundation that can affect their life for years.

For mothers, establishing paternity creates the legal basis for requesting child support. California law requires both parents to financially support their child, but that obligation cannot be enforced until the legal relationship between father and child is recognized.

How Do Unmarried Parents Establish Paternity in California?

California offers two primary paths: signing a Voluntary Declaration of Parentage (VDOP) or filing a court action to establish parentage.

Voluntary Declaration of Parentage

The most straightforward method is completing a Voluntary Declaration of Parentage (VDOP). Under California Family Code Section 7571, hospitals are required to provide unmarried parents with the opportunity to sign this form at the time of the child’s birth. The form is also available at local child support agencies, the California Department of Child Support Services, and vital records offices.

When both parents sign the VDOP, and it is filed with the California Department of Child Support Services, it carries the same legal weight as a court judgment establishing parentage. It is a powerful document, and both parents should understand what they are agreeing to before signing.

There is a window to rescind the declaration. Either parent may cancel it within 60 days of signing, or before any court proceeding related to the child, whichever comes first. After that window closes, setting aside a VDOP generally requires proving fraud, duress, or material mistake of fact, which is a much higher legal bar.

Court-Based Paternity Actions

When parents disagree about paternity, or when the voluntary declaration is not an option, either parent, the child, or the local child support agency can file a court action to establish parentage. Under California Family Code Section 7630, these petitions can be filed in the Superior Court of the county where the child lives.

In Santa Clara County, these cases are handled through the Santa Clara County Superior Court. The court may order genetic testing if paternity is disputed. California Family Code Section 7551 authorizes the court to order blood or genetic testing of the mother, child, and alleged father. If genetic testing satisfies California’s statutory requirements, including at least a 99% probability of parentage and the required relationship index, California law creates a presumption that the tested individual is the child’s genetic parent.

Once the court enters a judgment of paternity, both parents gain legally enforceable rights and responsibilities, including the ability to pursue custody, visitation, and child support orders.

What Happens After Paternity Is Established?

Once paternity is legally established, the court can address custody, visitation, and child support, all issues that directly shape a child’s day-to-day life.

Establishing paternity opens the door to the full range of family law proceedings. Parents can then seek formal custody and parenting time arrangements, which courts in California decide based on the best interests of the child under Family Code Section 3011. Child support calculations follow a statewide guideline formula that accounts for each parent’s income and the amount of time each parent spends with the child.

For many families in Campbell and the surrounding Santa Clara Valley, these issues carry genuine emotional weight. A child’s relationship with both parents and their financial security depends on getting this legal foundation right.

Common Mistakes Unmarried Parents Make

Waiting too long to address paternity is one of the most common and costly errors. Some parents assume that an informal arrangement, where a father is simply present in the child’s life, offers the same protections as a legal determination. It does not. Without a legal paternity order, a father has no enforceable right to see his child, and a mother has no legal mechanism to compel financial support.

Signing the Declaration of Paternity without understanding its implications is another risk. Once the 60-day rescission period passes, the declaration is treated like a court judgment. Anyone considering signing should take the time to understand what parental rights and responsibilities follow from that signature.
