If you are in immediate danger or concerned for your child’s safety, call 911. This article is general information, not legal advice for your specific situation.

What “Paternity” Means in California

In California, “paternity” (now often called legal parentage) is the legal recognition that a person is a child’s parent. Legal parentage is not just about biology — it’s about rights and responsibilities.

Once parentage is established, the court can issue orders involving:

• Child custody and visitation
• Child support and health insurance
• Reimbursement of pregnancy and birth costs
• Name changes
• Protective orders if safety is an issue

If you live in Walnut Creek, your parentage case will typically be handled through Contra Costa County Superior Court under the Uniform Parentage Act (UPA).

Why Establishing Paternity Matters for Your Child

Legal parentage helps ensure your child has access to:

• Financial support from both parents
• Medical insurance and healthcare coverage
• Inheritance rights
• Social Security, veterans, or other benefits
• A stable legal relationship with both parents

Just as importantly, it creates a framework for parenting time and decision-making, reducing uncertainty for everyone involved.

Colliss Law APC works with Walnut Creek parents who want to establish parentage proactively — and with parents whose situations have become contested or emotionally complex.

Two Main Ways to Establish Paternity in Walnut Creek

1) Voluntary Declaration of Parentage (VDOP)

If both parents agree on who the child’s parent is, the simplest path is signing a Voluntary Declaration of Parentage (VDOP). This form legally establishes parentage without going to court.

Key points about VDOPs:

• It’s often signed at the hospital when a child is born, but can be signed later.
• There is no fee to sign and file it.
• Once filed, it has the same legal effect as a court judgment of parentage.
• It allows the parent’s name to be added to the birth certificate.

Important: Signing this form is a major legal step. Parents have the right to speak with a lawyer or request genetic testing before signing.

How Colliss Law APC helps:
We review VDOP situations to make sure a voluntary declaration is appropriate, correctly completed, and truly protects your child’s best interests — especially if custody or support issues are likely later.

2) Court Case to Establish Parentage (UPA Case)

If the other parent will not sign a VDOP, if there’s uncertainty about biological parentage, or if custody/support needs to be decided by a judge, you can file a parentage case in Contra Costa County court.

A court case may be the right option when:

• One parent denies parentage
• Either parent wants DNA testing
• Custody or visitation must be set formally
• Child support needs to be ordered
• There are safety concerns needing court protection

What the court can do:
After parentage is established, the judge can issue binding orders on custody, support, health insurance, expenses, and more.

How Colliss Law APC helps:
We handle the filing, prepare supporting evidence, guide you through DNA testing if needed, and represent you at hearings in Walnut Creek and across Contra Costa County.

Step-by-Step: How a Walnut Creek Parentage Case Usually Works

While every case is unique, most follow a similar structure:

Step 1: File the Parentage Petition

One parent files a case under the Uniform Parentage Act in Contra Costa County Superior Court.

Step 2: Serve the Other Parent

The other parent must be formally served with the paperwork so they have legal notice and a chance to respond.

Step 3: Response and Possible DNA Testing

If parentage is disputed, the court can order genetic testing. The results help the judge establish legal parentage.

Step 4: Temporary Orders (If Needed)

The court may issue temporary custody or support orders while the case is pending, especially if the parents are not living together or the child needs stability right away.

Step 5: Final Parentage Judgment and Parenting/Support Orders

Once parentage is confirmed, the court issues final orders addressing custody, visitation, child support, and related issues.

Colliss Law APC stays involved from the first filing through final orders, making sure deadlines are met and your child’s needs are front and center.

What If You’re a Father Seeking Parental Rights?

Unmarried fathers do not automatically have enforceable custody or visitation rights until legal parentage is established. A VDOP or parentage case is the legal foundation for becoming a recognized parent with equal standing.

If you want to be part of your child’s life, avoid delays. The sooner parentage is established, the sooner you can request parenting time and decision-making rights through the court.

Colliss Law APC supports fathers in Walnut Creek who are ready to take that step responsibly and effectively.

What If You’re a Mother Seeking Support and Stability?

For mothers, establishing parentage is often the key to getting:

• Child support
• A consistent custody/visitation schedule
• Help with health insurance coverage
• A legally enforceable plan for co-parenting

If the other parent is uncooperative or absent, a court case may be necessary. We understand how stressful that can feel, and Colliss Law APC is here to guide you through the process with steady advocacy.

Can Paternity Be Challenged Later?

Yes. A VDOP or court judgment can be challenged in certain situations, but there are strict rules and deadlines.
Because changing legal parentage is high-impact for a child, courts take these cases seriously.

If you believe parentage was established incorrectly — or you’re responding to a challenge — it’s critical to get legal guidance early.
