Divorce and Family Law in California: A Complete Guide

California divorce runs on a handful of rules that shape almost every case: it is a pure no-fault system, it divides marital property as community property (presumptively 50/50), and it imposes a mandatory six-month waiting period before any divorce can be final — even when both spouses agree on everything from day one. This guide is the overview that ties the whole process together: the grounds, where and how you file, who gets what, how children are handled, how long it takes, and what it costs, with links to in-depth companion guides for each piece.

This is general information about California law, not legal advice. Every case has facts that change the analysis — especially where children, a business, significant assets, or any history of abuse are involved.

California divorce at a glance

The foundation: no-fault and community property

No-fault. California was the first state to adopt no-fault divorce, and it does not ask why a marriage failed. The only ground for a standard divorce is "irreconcilable differences" that have caused the irremediable breakdown of the marriage (Fam. Code § 2310). Adultery, cruelty, and other misconduct generally have no effect on whether the divorce is granted, and a blameless spouse cannot defeat the divorce. Conduct can still matter at the edges — domestic violence affects custody, and wasting community money (for example, on an affair) can affect the property split — but you never have to prove wrongdoing.

Community property. California is a community property state. Under Fam. Code § 760, almost everything either spouse earns or acquires during the marriage — income, the house, retirement contributions, businesses, and debts — belongs to both spouses equally, regardless of whose name is on the title or account. Property owned before marriage, and gifts or inheritances received by one spouse, are generally that spouse's separate property (Fam. Code § 770). The fights over classification (Is this separate or community? Did separate property get commingled?) are where much of the money in a divorce is actually won or lost.

The process, step by step

A California divorce moves through a predictable sequence:

1. Confirm residency. One spouse must have lived in California six months and in the filing county three months (Fam. Code § 2320).
2. File the Petition (Form FL-100) and Summons (FL-110) with the Superior Court and pay the filing fee. The Summons carries Automatic Temporary Restraining Orders (ATROS) that immediately bar both spouses from moving assets, changing insurance, or taking the children out of state.
3. Serve your spouse. You cannot hand the papers over yourself; service is by another adult, a process server, or the sheriff. The respondent has 30 days to file a Response (FL-120).
4. Exchange Preliminary Declarations of Disclosure — mandatory financial disclosure (Schedule of Assets and Debts, FL-142, and Income and Expense Declaration, FL-150). Hiding assets carries serious penalties.
5. Resolve the issues by written agreement (a Marital Settlement Agreement), by default if the respondent never answers, or by trial — but no judgment can be entered before the six-month waiting period expires.

The timeline, milestone by milestone

It helps to see where the six-month floor sits inside the larger calendar. A typical uncontested case moves like this:

• Day 0 — filing. The petitioner files FL-100 and FL-110 and pays the fee. The Automatic Temporary Restraining Orders bind the petitioner immediately.
• Within ~30 days — service. The respondent is served; ATROS now bind them too, and their 30-day window to respond begins.
• Day 30–90 — response and disclosures. The respondent files FL-120 (or the case heads toward default), and both spouses exchange Preliminary Declarations of Disclosure (FL-142, FL-150).
• As needed — temporary orders. Either spouse can request temporary support, custody, or use of the home while the case is pending, usually by Request for Order (FL-300).
• Month 3–6 — settlement. Most couples negotiate a Marital Settlement Agreement covering every issue.
• Month 6+ — judgment. The court enters judgment on the agreement; marital status cannot terminate before the six-month mark (Fam. Code § 2339).

Contested cases add steps — discovery, custody mediation, expert valuations, settlement conferences, and possibly trial — which is why they commonly run one to two years or more. The six months is a floor, never a ceiling.

The six-month waiting period

California imposes a hard floor: no divorce can be final until at least six months after the respondent was served with the summons and petition, or first appeared in the case — whichever happened first (Fam. Code § 2339). This applies even when both spouses sign a complete agreement on the first day. The six months is the earliest the marital status can be terminated; the rest of the case (property, support, custody) can sometimes resolve sooner or later, but the marriage itself is not dissolved before the clock runs.

Dividing property and debt

Because California is a community property state, the default is that everything acquired during the marriage is divided equally (Fam. Code § 2550). But "equal" is not always a simple split-everything-in-half: separate property has to be identified and traced, and certain assets need special handling. Retirement plans and pensions usually require a separate court order called a Qualified Domestic Relations Order (QDRO) to divide without taxes or penalties. A house bought before marriage but paid down with marital income raises a Moore/Marsden apportionment between separate and community interests. Debts are community too — a credit card in one spouse's name alone can still be a shared obligation. See property division in a California divorce.

The work in a property case is rarely the arithmetic; it is the characterization. The spouse claiming a separate-property interest in a commingled account generally must trace it back to a separate source through records, and if tracing fails the whole account can be treated as community. A business started or grown during the marriage usually needs a professional valuation, and where a spouse built up a pre-marital business during the marriage, courts apportion the community's share of the growth (the Pereira and Van Camp methods). Disclosure runs through all of it: spouses owe each other a continuing fiduciary duty to disclose every asset and debt (Fam. Code §§ 721, 1100), and a deliberate concealment can cost the hiding spouse the entire hidden asset as a sanction (Fam. Code § 1101).

Spousal support (alimony)

Spousal support is not automatic. During the case, courts often set temporary support using a local guideline calculator. For support after judgment, the court weighs the statutory factors in Fam. Code § 4320 — the marital standard of living, each spouse's earning capacity and needs, the supporting spouse's ability to pay, the duration of the marriage, and others — rather than a formula. The length of the marriage matters: for a "marriage of long duration" (generally 10 years or more), the court retains jurisdiction over support potentially indefinitely (Fam. Code § 4336), while support in shorter marriages is often expected to last about half the length of the marriage. See spousal support in California.

The § 4320 factors include the marital standard of living, each spouse's earning capacity and the time needed to acquire skills or training, the supported spouse's contributions to the other's education or career, the supporting spouse's ability to pay, the age and health of the parties, any documented history of domestic violence, the tax consequences, and the goal that the supported spouse become self-supporting within a reasonable time. Courts often issue a Gavron warning formally advising the supported spouse of that expectation. Long-term support generally remains modifiable on a material change in circumstances and ordinarily ends on the death of either spouse or the supported spouse's remarriage (Fam. Code § 4337); the supported spouse's cohabitation with a romantic partner creates a rebuttable presumption of reduced need (Fam. Code § 4323).

Children: custody, parenting time, and support

California divides child custody into legal custody (the authority to make major decisions about health, education, and welfare) and physical custody (where the child lives), and either can be joint or sole. Courts decide both under the best-interests-of-the-child standard in Fam. Code §§ 3011 and 3020, with the health, safety, and welfare of the child as the primary concern and no automatic preference for either parent (Fam. Code § 3040). Where one parent has committed domestic violence, a rebuttable presumption against awarding that parent custody applies (Fam. Code § 3044). See child custody in California.

Before a judge rules on a contested custody dispute, California requires the parents to attend mediation — called Child Custody Recommending Counseling in many counties — through Family Court Services (Fam. Code § 3170), and many cases settle there with an agreed parenting plan. Custody is implemented through that written plan, which sets the regular timeshare, holidays, vacations, exchanges, and how major decisions are made. A child 14 or older generally has the right to address the court about custody (Fam. Code § 3042), though the child's preference is one factor, never the deciding one. Move-away (relocation) requests are among the most heavily litigated modifications, analyzed under California Supreme Court decisions such as In re Marriage of Burgess and In re Marriage of LaMusga; and modifying a final custody order generally requires a significant change in circumstances.

Child support is calculated under a mandatory statewide guideline formula (Fam. Code § 4055) using both parents' net incomes, the percentage of time each parent has the child, and add-ons like health insurance and childcare. Courts use a certified calculator to apply the formula; the guideline amount is presumptively correct. See child support in California.

Income for support is defined broadly (Fam. Code § 4058) — wages, self-employment, bonuses, commissions, rental and investment income, and many benefits — and a court can impute income to a parent who is deliberately unemployed or underemployed. On top of the base figure, courts add mandatory add-ons for work-related childcare and the child's uninsured health-care costs (Fam. Code § 4062), usually shared in proportion to income. Support generally lasts until the child turns 18 (or 19 if still a full-time high school student living at home, Fam. Code § 3901), can be modified on a change in circumstances, and is backed by powerful enforcement — wage garnishment, tax-refund interception, and license suspension — through the Department of Child Support Services. Arrears accrue 10% interest and are not dischargeable in bankruptcy.

Domestic violence and restraining orders

The Domestic Violence Prevention Act (DVPA) — Fam. Code § 6200 et seq. — lets a person seek a protective order against a spouse, former spouse, cohabitant, dating partner, co-parent, or other close relation. "Abuse" under the DVPA is broad: it includes not only physical harm or the threat of it but also stalking, harassment, threats, and disturbing the other person's peace (Fam. Code § 6320). A Domestic Violence Restraining Order (DVRO) is a separate, faster track than the divorce itself.

The process moves quickly. A person files a Request for Domestic Violence Restraining Order (Form DV-100). A judge can issue a Temporary Restraining Order (TRO) the same or next day, often without the other side present, and the court sets a hearing within about 21 days. After that noticed hearing, the judge can issue a "permanent" order lasting up to five years, which can be renewed. A DVRO can include personal-conduct (no-contact) orders, stay-away orders, a move-out order removing the restrained person from a shared home, and temporary custody, parenting-time, and support orders. Violating a DVRO is a crime.

Because a finding of abuse triggers the Fam. Code § 3044 rebuttable presumption against awarding the abusive parent custody, a DVRO can significantly shape a divorce involving children — and a documented history of domestic violence is also a factor in spousal support (Fam. Code § 4320). California courts publish DV forms and self-help resources, and victim advocates can help file. If there is any immediate danger, call 911; if there is any safety concern at all, seek help right away rather than waiting for the divorce to address it.

Three ways a divorce ends

• Uncontested / settlement. Both spouses sign a Marital Settlement Agreement resolving every issue, and the judge enters judgment on the papers — usually without a hearing. Fastest and cheapest.
• Default. The respondent never files a Response, and the court grants the divorce on the petitioner's requests. A spouse cannot stop a divorce by ignoring it — default exists for exactly that situation.
• Contested trial. The spouses cannot agree on one or more issues and a judge decides after trial. Even so, the great majority of California divorces settle before trial.

Divorce vs. legal separation

California also allows legal separation, which resolves the same issues — property, support, and custody — but leaves the spouses legally married, so neither can remarry. People choose it for religious reasons, to preserve health insurance, or because the residency requirement for divorce has not yet been met (legal separation has no residency requirement). Either spouse can later ask the court to convert it to a divorce.

What it costs

There are two separate costs: the court and the attorney. The first-appearance filing fee is roughly $435–$450 (it varies by county), and the responding spouse pays a separate fee; fee waivers are available based on income. Attorney fees are the real variable: California family lawyers typically bill $300–$500 per hour against an upfront retainer. A genuinely uncontested divorce handled with limited help often totals a few thousand dollars; a contested divorce with custody or asset disputes commonly runs $10,000–$30,000 or more. The single biggest cost driver is conflict — every contested issue adds attorney hours.

Do you need a lawyer?

You are not required to hire one, and California courts publish self-help packets for simple cases. But the stakes rise quickly when there are minor children, a business, real estate, retirement accounts requiring a QDRO, hidden or hard-to-value assets, or any history of abuse. Even in an amicable case, a single consultation or a review of your draft agreement can catch expensive, hard-to-undo mistakes.

Frequently asked questions

Is California a no-fault divorce state?

Yes. The only ground for a standard divorce is irreconcilable differences (Fam. Code § 2310). Neither spouse has to prove the other did anything wrong, and one spouse cannot block the divorce by disagreeing.

How long does a divorce take in California?

The absolute minimum is six months from the date the respondent is served or appears, because no divorce can be final any sooner (Fam. Code § 2339) — even with full agreement. In practice, uncontested cases finalize in roughly six to nine months, and contested cases take one to two years or more.

Will everything be split exactly 50/50?

Community property — what you acquired during the marriage — is divided equally (Fam. Code § 2550). But property owned before marriage, plus gifts and inheritances received individually, is generally separate and stays with that spouse, and commingled or improved property can require tracing and apportionment. "Equal" applies to the community estate, not to every individual asset.

Can I get divorced if my spouse doesn't want one?

Yes. Because California is no-fault, one spouse cannot prevent a divorce by refusing to agree or sign. If your spouse won't participate, you serve them and, after the response window closes, proceed by default. Their refusal changes the path and timeline, not the outcome.

How is child support calculated in California?

By a mandatory statewide guideline formula (Fam. Code § 4055) based on both parents' net incomes and the percentage of time each spends with the child, plus add-ons such as health insurance and childcare. Courts apply the formula with a certified calculator, and the guideline figure is presumptively correct.

Do I have to go to court to get divorced?

Often, no. If you and your spouse reach a complete written agreement, the judge can usually enter the judgment on the papers without either of you appearing. Court appearances are more likely for contested temporary-orders hearings, custody disputes, or a trial.

What is the difference between divorce and legal separation?

A legal separation resolves the same issues but leaves you legally married, so you cannot remarry. People use it for religious or insurance reasons or when they don't yet meet the six-month residency requirement for divorce. It can later be converted to a divorce.

Does it matter who files first?

Legally, very little. California is no-fault, so the spouse who files (the petitioner) gains no advantage on the outcome, and filing first does not make you more likely to "win." The main practical effects are that the petitioner sets the case in motion, controls the initial filing, and at trial presents evidence first. Either spouse can request temporary custody, support, or property orders regardless of who filed.

How is spousal support different from child support?

Child support follows a mandatory statewide guideline formula (Fam. Code § 4055) and is fairly predictable. Long-term spousal support is discretionary — the court weighs the Fam. Code § 4320 factors rather than a formula — and its duration depends heavily on the length of the marriage, with the court retaining jurisdiction potentially indefinitely for marriages of 10 years or more (Fam. Code § 4336).

What is a domestic violence restraining order, and how does it affect a divorce?

Under the Domestic Violence Prevention Act (Fam. Code § 6200 et seq.), a person can seek a restraining order against a spouse or partner. A judge can issue a temporary order quickly and, after a hearing, an order lasting up to five years that can include stay-away, move-out, and temporary custody and support terms. Because a finding of abuse triggers the Fam. Code § 3044 presumption against awarding the abusive parent custody, these orders can strongly affect a divorce involving children.
