Parentage is the legal parent-child relationship — and establishing it is often the first step before custody or support can be decided.
The Uniform Parentage Act
California’s Uniform Parentage Act, Fam. Code § 7600 et seq., governs establishing the legal parent-child relationship. When parents are married, parentage is usually presumed; when they aren’t, it frequently has to be established before the family court can act.
The Voluntary Declaration of Parentage
A Voluntary Declaration of Parentage (VDOP), under Fam. Code § 7570 et seq., is a form both parents sign. Once signed, it has the force of a judgment establishing parentage — meaning the parents don’t need a contested court hearing to make it official. Hospitals often offer it at the time of birth.
Why it matters
Establishing parentage is the legal predicate for two big things: custody and visitation rights, and child-support obligations. Until parentage is established, a person generally can’t be ordered to pay support and may not have enforceable custody or visitation rights. The California Courts self-help center explains the forms and process.
How it connects
Once parentage is established, the court can address child custody and child support.

- What is parentage and why does it matter?
- Parentage is the legal parent-child relationship, governed by the Uniform Parentage Act (Fam. Code § 7600 et seq.). Establishing it is the legal predicate for custody and visitation rights and for child-support obligations, so unmarried parents often have to establish it first.
- What is a Voluntary Declaration of Parentage?
- A Voluntary Declaration of Parentage (VDOP), under Fam. Code § 7570 et seq., is a form both parents sign. Once signed, it has the force of a judgment establishing parentage — without going to a contested hearing.
- How does parentage relate to custody and support?
- It comes first. Until parentage is established, a person generally can't be ordered to pay child support and may not have enforceable custody or visitation rights. Establishing parentage opens the door to both.

- California Child Custody: Legal vs. Physical & Best Interest California splits custody into legal (decision-making) and physical (where the child lives), each of which can be joint or sole. Courts decide by the child's best interest, weighing § 3011 factors like health, safety, and abuse history. The court cannot prefer a parent based on sex, gender, or sexual orientation.
- California Child Support: The Guideline Formula California sets child support with a statewide uniform guideline formula (Fam. Code § 4055) based on both parents' incomes and timeshare. A major reform (SB 343) became operative September 1, 2024, changing how income is allocated and the low-income adjustment.

- California Divorce: No-Fault Grounds, Residency & Timeline California is a pure no-fault state. Almost every divorce rests on 'irreconcilable differences' (Fam. Code § 2310). You must be a California resident six months and a county resident three months before filing (§ 2320), and a divorce can't be final until at least six months after the respondent is served or appears (§ 2339).
- California Domestic Violence Restraining Orders (DVRO) California's Domestic Violence Prevention Act (Fam. Code § 6200 et seq.) lets people in covered relationships seek a restraining order. 'Abuse' is broader than physical injury (§ 6203), and a DVRO can order no-contact, stay-away, move-out, and address custody, support, and firearm restrictions.
- California Property Division: Community Property California is a community property state. Property acquired during the marriage (Fam. Code § 760) is generally divided equally — 50/50 — absent a written agreement (§ 2550). Separate property owned before marriage or received by gift or inheritance (§ 770) isn't divided. This differs from equitable-distribution states.
- California Spousal Support: Factors & the 10-Year Rule California has temporary support during a case and long-term support at judgment. Long-term support is set by the Fam. Code § 4320 factors, not a formula. Under § 4336, a marriage of 10+ years is presumed 'of long duration' so the court retains jurisdiction indefinitely — but that's not an automatic right to lifetime support.
