How to Establish Paternity in California (Los Angeles) — A Practical Guide

I’m Tim Blankenship from Divorce661. If you weren’t married when your child was born, establishing paternity is the first step to securing custody, visitation, and support rights. Getting legal clarity about who the father is protects both parents and, most importantly, the child. Below I walk you through how paternity works in California, what to do when both parents agree, what happens when there’s a dispute, and how we can help you every step of the way.

Why Establishing Paternity Matters

Establishing paternity creates legal recognition of the father’s role. That recognition is the gateway to:

• Filing for custody and visitation
• Requesting child support
• Accessing parental rights and responsibilities
• Ensuring the child has access to both parents’ medical history, insurance, benefits, and social security

“Establishing paternity is the first step in securing custody, visitation, and support rights.”

Two Routes to Establish Paternity in California

1. When Both Parents Agree: Voluntary Declaration of Parentage

If both parents agree on who the father is, the process is simple. You can sign a Voluntary Declaration of Parentage (VDOP) at the hospital when the child is born or later using a notarized form.

• Sign at the hospital or obtain the VDOP form from the county office.
• If signing later, complete the form and have it notarized.
• Filing the VDOP establishes legal parentage without court involvement.

Completing the VDOP ensures both parents share equal rights and responsibilities and allows you to move forward with custody, visitation, or support arrangements in a cooperative way.

2. When One Parent Disagrees: Court Petition and DNA Testing

If paternity is disputed, the court will typically get involved. The usual steps include:

• Filing a petition to establish paternity with the family court.
• Requesting a court-ordered DNA test to confirm biological parentage.
• Once paternity is confirmed, the court can issue orders for custody, visitation, and support.

The court’s primary focus is the child’s best interests. DNA testing provides the objective proof the court needs to make legal determinations about parental rights.

Real Client Example — Los Angeles Paternity Case

Recently we helped a client in Los Angeles who wanted custody but wasn’t legally recognized as the father. He couldn’t seek custody or visitation because paternity hadn’t been established. We filed the necessary petitions, obtained a court-ordered DNA test, and once paternity was confirmed, he gained full parenting rights. That confirmation unlocked his ability to seek custody, visitation, and support.

At Divorce661 we handled the filings, coordinated court dates, and guided him through the process from start to finish.

2. If paternity is disputed, file a petition with the family court requesting establishment of paternity.

Common Questions

Do unmarried fathers automatically have rights?

No. In California, an unmarried father must establish paternity to gain legal rights to custody, visitation, and support unless paternity is otherwise legally recognized (for example, by a signed VDOP).

Is DNA testing always required?

Not if both parents voluntarily sign the VDOP. DNA testing is typically used when one parent disputes paternity and the matter proceeds to court.

What if the mother refuses to cooperate?

If voluntary parentage is not possible because one parent refuses to cooperate, you can petition the court to establish paternity and request DNA testing. The court has the authority to order testing and make legal determinations based on the results.
