Paternity Attorney in Orange County

A Certified Family Law Specialist Representing Mothers & Fathers Throughout Orange County

Paternity (California courts use the term parentage) is the formal legal determination of who a child’s father is. Until that determination is made, an unmarried father has no enforceable right to custody or visitation, and a mother has no legal basis to pursue child support. Orange County family courts can’t issue custody, visitation, or support orders until parentage is established. The stakes for both parents and the child are real from day one.

How Paternity Is Established in California

California law provides three primary pathways to establish parentage. The right one depends on whether the parents are married, whether they agree, and whether paternity is disputed.

The Marital Presumption

Under California Family Code section 7540, when spouses cohabited at the time of conception and birth, the child is conclusively presumed to be a child of the marriage. No paternity action is needed. This presumption carries very limited exceptions and doesn’t apply if the husband was impotent or sterile at the time of conception and the child wasn’t conceived through assisted reproduction.

Voluntary Declaration of Parentage

Unmarried parents who agree on paternity can sign a Voluntary Declaration of Parentage (VDOP, form CS 909) without going to court. When signed and filed with the California Department of Child Support Services, it carries the same legal weight as a court order. The VDOP can be signed at the hospital at birth or later before a notary. In Orange County, the Paternity Opportunity Program, administered by the OC Department of Child Support Services, handles these filings. Either parent has 60 days from signing to rescind it using form CS 915; after that window closes, rescission requires a court order.

Court-Filed Petition (FL-200)

If parents disagree or paternity is uncertain, either parent, the child’s representative, or the Orange County Department of Child Support Services may file a Petition to Establish Parental Relationship (form FL-200) in Orange County family court under California Family Code section 7630. This is the contested pathway, and it often leads to genetic testing.

DNA Testing in Disputed Paternity Cases

When paternity is contested, the Orange County family court may order the mother, alleged father, and child to undergo genetic testing under California Family Code section 7551. Either parent can request a court-ordered test by filing a Request for Order, or both may submit a written agreement to the judge.

Testing uses a buccal (cheek) swab and is non-invasive. Under Family Code section 7555, a paternity index score of 100 or greater creates a rebuttable presumption of biological fatherhood. At-home DNA tests don’t satisfy the court’s evidentiary standard and can’t be used to override formal court-ordered results, though they may be introduced in later proceedings as evidence of early doubt. A party who refuses a court-ordered test risks being held in contempt. If testing confirms the alleged father isn’t the biological father, the action typically ends. If paternity is confirmed, the case proceeds to custody, visitation, child support, birth costs, and attorney’s fees.

Presumed Parentage & Parentage by Estoppel

Biological connection isn’t the only basis for legal parentage in California. Family Code section 7611 recognizes presumed parentage when a person receives a child into their home and openly holds the child out as their natural child. These cases turn on conduct and relationship history, not just genetics.

Parentage by estoppel is a related doctrine: a court may declare someone a legal parent based on how they acted toward the child, regardless of biology. These cases are heavily fact-driven and typically require a trial. Family Code section 7612(c) also allows a court to find that a child has more than two legal parents when limiting parentage to two people would be detrimental to the child. Establishing parentage for same-sex partners who weren’t married when a child was born, or in cases involving assisted reproduction, may require additional legal steps. Cases like these benefit from counsel with deep knowledge of California family law.

Rights & Responsibilities That Follow Parentage

Legal parentage isn’t just a label. Once established, a child gains enforceable rights across several areas:

• Financial support from both parents
• Access to both parents’ family and medical history
• Inheritance rights under California intestate succession law
• Eligibility for health insurance and government benefits, including Social Security survivor or disability benefits tied to the father’s earnings record

A legally established father gains the right to seek custody and visitation orders and to participate in decisions about the child’s education, healthcare, and upbringing. Child support is calculated under the statutory guideline formula in Family Code section 4055; the court may also allocate costs for childcare, healthcare, and birth-related expenses. None of these orders can be entered until parentage is established, which is why acting promptly can protect both the child’s interests and your legal standing.

Our Approach to Paternity Cases in Orange County

We handle both contested and uncontested paternity matters for Orange County clients, from the initial filing through final orders. Attorney Amy Neshanian, a Certified Family Law Specialist, leads every case directly. Our boutique firm structure means you won’t be passed between paralegals or junior staff. You work with our team, and we keep you informed at every stage, whether your matter resolves by agreement or requires a trial.

Paternity cases frequently intersect with child custody, visitation, child support, and, when relevant, domestic violence restraining orders. All of these issues can be addressed within the same proceeding. If temporary custody or visitation is needed while your case is pending, we can request those orders under Family Code section 7604. When parents agree on all issues, we can help document that agreement in a form the court can sign and enforce, leaving nothing open to future dispute.
