How to File for Divorce in California: Residency, Grounds & Waiting Period

California's No-Fault Divorce: The Short Answer

If you are ready to end your marriage in California, you do not need to prove that your spouse did anything wrong. California is a no-fault divorce state: the only recognized grounds for dissolving a marriage are irreconcilable differences causing an irremediable breakdown of the marriage, or the permanent legal incapacity of one spouse to make decisions. (Cal. Fam. Code § 2310) In practice, nearly every California divorce is filed on the basis of irreconcilable differences — you simply state that the marriage has broken down beyond repair. Your spouse cannot block the divorce itself by refusing to agree.

That said, California has specific rules about who can file, how long the process takes, and what paperwork gets things started. Getting these right from the beginning prevents delays and avoids wasted fees.

Who Can File: California Residency Requirements

Before filing for divorce in a California superior court, at least one spouse must satisfy two residency requirements — both measured immediately before the date of filing: (Cal. Fam. Code § 2320(a))

• State residency: At least one spouse must have lived in California for a minimum of 6 months.
• County residency: At least one spouse must have lived in the specific county where you plan to file for a minimum of 3 months.

Both conditions must be met at the time you file — not just at some point in the past. If you recently moved to California or relocated to a new county within the state, you may need to wait before you can file. If neither spouse currently qualifies, California courts cannot accept your divorce petition.

There is a useful alternative for people who do not yet meet the residency requirements: legal separation. Legal separation addresses the same issues as divorce — property division, spousal support, child custody, and child support — through the same court process. The key difference is that it does not end the marriage, and it does not carry the 6-month waiting period that applies to divorce. Once you satisfy the residency requirements, a legal separation can be converted to a divorce. (California Courts Self-Help Guide, Divorce)

Grounds for Divorce in California

California law recognizes only two grounds for dissolving a marriage: irreconcilable differences that have caused an irremediable breakdown, or the permanent legal incapacity of one spouse to make decisions. (Cal. Fam. Code § 2310) Because California is a no-fault state, fault, infidelity, and misconduct are not grounds for divorce and do not need to be proven.

This has a practical consequence: your spouse cannot contest the divorce itself. They may delay proceedings and dispute the terms — how property is divided, who pays support, how custody is arranged — but the court will not refuse to grant a divorce solely because one spouse wants to remain married.

The 6-Month Waiting Period

Time-sensitive fact: A California divorce cannot be finalized in less than 6 months, regardless of how cooperative both parties are. Under state law, no judgment of dissolution becomes final until six months have expired from the date the respondent (your spouse) is served with the summons and petition, or the date of the respondent's first appearance in the case — whichever comes first. (Cal. Fam. Code § 2339(a))

The clock starts with service, not with your filing date. If serving your spouse takes several weeks after you file, those weeks are added to your overall timeline. The California Courts confirm that divorce in California takes at least 6 months to finish. Many divorces take considerably longer when the parties cannot reach agreement on property, support, or custody.

Legal separation, by contrast, does not carry this mandatory waiting period — one reason some couples use it as an intermediate step while a divorce case works through the courts.

The Four-Part Divorce Process in California

The California Courts break the divorce process into four main parts: (California Courts Self-Help Guide, Divorce)

1. Starting the case — Filing the required forms with the court and serving your spouse.
2. Sharing financial information — Both spouses must disclose their income, assets, debts, and expenses. This step is mandatory even in uncontested divorces.
3. Making decisions — Resolving all issues including property division, spousal support, child custody, and child support, either by agreement or through court hearings.
4. Finalizing — Submitting final paperwork and receiving the court's judgment of dissolution.

Working through all four parts accounts for the 6-month minimum. Cases that stall at step three — particularly disputes over custody or high-value property — can take significantly longer.

Forms and Filing Fees

To open a California divorce case, you need two core forms filed with the superior court in the county where you qualify: (California Courts Self-Help Guide, Fill out your divorce forms)

• Form FL-100 — Petition—Marriage/Domestic Partnership. This is the document that formally opens your case and states what you are asking the court to order.
• Form FL-110 — Summons. This is the legal notice that must be formally served on your spouse.

Both forms are available free through the California Courts website. Additional forms will be required as your case moves forward — particularly the mandatory financial disclosure forms, which both spouses must complete regardless of whether the divorce is uncontested.

The filing fee to start a case is generally about $435 to $450, though the exact amount may vary by county. (California Courts Self-Help Guide, File divorce papers) If you cannot afford the fee, you can apply for a fee waiver at the time you file. Fee waivers are a standard, widely used option — do not let cost alone stop you from understanding your rights.

Special Situations: Military Families

If you or your spouse is an active-duty servicemember, two federal laws add important considerations to a California divorce.

The Servicemembers Civil Relief Act (SCRA), 50 U.S.C. § 3932, allows a servicemember whose military duties materially affect their ability to appear in court to request a stay — a legal pause — of at least 90 days in a divorce, custody, or support proceeding. This protection prevents a deployed servicemember from receiving a default judgment while they are unable to participate in the case.

The Uniformed Services Former Spouses' Protection Act (USFSPA), 10 U.S.C. § 1408, allows California courts to treat military "disposable retired pay" as marital property subject to division under California law. However, direct payment to a former spouse through the Defense Finance and Accounting Service is only available when the couple was married at least 10 years overlapping at least 10 years of the servicemember's qualifying military service — the so-called "10/10 rule." There is no automatic federal entitlement to any particular share; how much, if anything, a spouse receives is governed by California's property-division rules.

Child Custody and Support: Interstate Considerations

If your divorce involves children and either parent may move to another state, the Uniform Child Custody Jurisdiction and Enforcement Act (UCCJEA) determines which state's courts have authority over custody. California has adopted the UCCJEA, as have 48 other states and the District of Columbia. If you have questions about which state would have jurisdiction over your children, confirm the specifics with your California court.

On child support: once a support order is in place, past-due amounts generally cannot be reduced retroactively under the federal Bradley Amendment, 42 U.S.C. § 666(a)(9)(C). If your financial circumstances change — a job loss, reduced income — the correct step is to return to court promptly and request a modification going forward. Arrears that have already accrued generally cannot be erased after the fact.

What You Can Do in California: Step-by-Step

1. Verify residency. Confirm that at least one spouse has lived in California for 6 months and in your intended filing county for 3 months, both measured immediately before the date you plan to file. (Cal. Fam. Code § 2320(a)) If you do not yet qualify, calculate when you will — or explore legal separation as an interim step.
2. Download Forms FL-100 and FL-110. Get both forms from the California Courts Self-Help website at selfhelp.courts.ca.gov. Read the accompanying instructions carefully before filling them out.
3. File at your county superior court. Bring the completed forms to the clerk's office. Pay the filing fee (generally $435–$450) or submit a fee waiver application at the same time if cost is a barrier. (California Courts Self-Help Guide, File divorce papers)
4. Serve your spouse promptly. After filing, someone other than you must formally serve the summons and petition on your spouse — you cannot serve the papers yourself. Time-sensitive: The 6-month waiting period under Cal. Fam. Code § 2339(a) does not begin until your spouse is served or makes an appearance. Delays in service push your earliest possible finish date further out.
5. Complete the mandatory financial disclosures. Both spouses must exchange detailed information about income, assets, debts, and expenses. This step cannot be skipped, even if you agree on everything.
6. Resolve all open issues. Work out property division, support, and custody through negotiation, mediation, or court hearings. An uncontested divorce — where both spouses reach full agreement — moves more smoothly and typically costs less.
7. Finalize after the 6-month period. Once the statutory waiting period has passed and all issues are resolved, submit the final required paperwork. The court issues a judgment of dissolution, and the marriage is legally ended.

Legal Separation: An Alternative Worth Knowing

Not everyone who separates is ready to divorce — or meets the residency requirements yet. Legal separation in California resolves the same issues as divorce (property, support, custody) through the same four-step court process, but it does not end the marriage and carries no mandatory 6-month waiting period. (California Courts Self-Help Guide, Divorce) It can also be a practical choice when remaining married provides insurance or other benefits, or when one spouse has religious objections to divorce. A legal separation can be converted to a divorce later if circumstances change and residency requirements are met.
