The California divorce process is procedural, which is a polite word for "there are a lot of forms and they have to be done in a particular order." The good news is that the order is well-defined and the forms are publicly available. The harder news is that small mistakes — wrong form number, missing signature, improper service — can cost months.

§ 01Before you file

Some things to do before filing makes the rest of the process dramatically smoother:

  • Gather financial records: the last three years of tax returns, recent pay stubs, account statements for everything in either name, mortgage statements, deeds, retirement account statements, business records.
  • Make a list of community and separate property: a rough first draft, even if you don't know how things will be characterized — having the inventory matters more than getting the legal labels right at this stage.
  • Note the date of separation — the day you and your spouse stopped behaving as a married couple. This date will matter throughout the case.
  • Decide whether you need an attorney for the case. For uncomplicated cases without significant assets, kids, or support disputes, a self-help approach (or services like Hello Divorce) can work. For anything more complicated, the cost of an attorney is almost always less than the cost of mistakes made without one.

§ 02The steps, in order

  1. File the Petition (FL-100). The petitioner files Form FL-100 (Petition — Marriage/Domestic Partnership) with the Superior Court in the county where they meet the residency requirement. If there are children, Form FL-105 (Declaration Under UCCJEA) is also required. Filing fee as of writing is around $435–$450, with fee waivers (FW-001) available for low-income filers.
  2. Serve the other spouse. The other spouse must be personally served with the petition, summons (FL-110), and any related documents. You cannot serve them yourself — service must be done by an adult who is not a party (a process server, a friend over 18, or the sheriff). Proof of service (FL-115) is then filed with the court. Until proper service happens, the case does not really move.
  3. Response (FL-120). The respondent has 30 days from the date of service to file a response. If no response is filed, the petitioner can ask the court for a default judgment, though the court will still require disclosures and a fair division of property.
  4. Preliminary Declarations of Disclosure. Within 60 days of filing the petition (and the response), each spouse must serve the other with a Preliminary Declaration of Disclosure: a Schedule of Assets and Debts (FL-142 or FL-160), an Income & Expense Declaration (FL-150), the last two years of tax returns, and a written disclosure of all material facts about community property and finances. This is mandatory. Skipping it is the most common procedural problem in California divorces.
  5. Temporary orders, if needed. If you need temporary support, exclusive use of the family home, restraining orders, or temporary custody orders while the case is pending, you file a Request for Order (FL-300) and get a hearing date. Many cases run on temporary orders for many months while the larger case works through the system.
  6. Discovery. Each side investigates: written questions (interrogatories), document requests, depositions, subpoenas to banks and employers. Discovery is where lawyers spend most of the billable hours in a contested case, and where most of the case's facts come into focus.
  7. Mediation, settlement, or trial. The vast majority of California divorces settle without trial. Settlement happens through direct negotiation between attorneys, formal mediation, settlement conferences with the court, or collaborative process. When a case actually goes to trial, it is typically because the parties cannot agree on one or two specific issues — most often custody, the value of a business, or significant separate-property claims.
  8. Final Declarations of Disclosure. Before judgment, both parties exchange a second round of disclosure — current versions of the financial documents from earlier — unless this requirement is waived by stipulation, which is common in fully-settled cases.
  9. Judgment (FL-180). The court enters a judgment that ends the marriage, divides property, sets support, and resolves custody. If the parties agreed, the judgment is based on a Marital Settlement Agreement attached to the FL-180. If they didn't, the judgment reflects the trial court's rulings.
  10. Six-month waiting period. Even when everything else is done, the court will not enter a final judgment terminating the marriage until at least six months and one day have passed since the respondent was served (or filed a response, whichever was earlier).
  11. Post-judgment work. QDROs for retirement accounts, deed transfers for real estate, refinancing of joint debts, name changes, updating beneficiaries on life insurance and accounts. The judgment ends the marriage, but the unwinding takes weeks or months more.

§ 03Realistic timelines

Uncontested, no children, no significant assets
6 to 9 months. Limited by the six-month waiting period and the time to prepare disclosures and the judgment.
Uncontested with children or moderate assets
9 to 12 months. The settlement agreement takes longer to draft, and disclosure is more involved.
Contested but settles before trial
12 to 24 months. Most of the time is discovery and back-and-forth negotiation.
Contested through trial
2 to 4 years. Trials are scheduled months out, sometimes years out, and post-trial work continues for some time after a verdict.

§ 04Costs

California divorces vary in cost more than almost any other legal matter. A truly uncontested DIY divorce can be done for the filing fees alone — about $1,000 total when you account for both spouses' fees and document service. An uncontested divorce with attorney help typically runs $3,000 to $8,000. A contested case costs $20,000 to $100,000+ per spouse, with high-asset cases reaching well into six figures and occasionally seven.

The biggest drivers of cost are: how much the parties fight, whether there's a business or complex asset to value, whether custody is contested, and whether discovery is heavily used. The smallest factor, surprisingly often, is the lawyer's hourly rate. Two careful attorneys at $500 an hour spend less time fighting than two combative attorneys at $300 an hour.

§ 05Self-help options

For relatively simple cases, California has several self-help paths. Most counties have a Self-Help Center — physical offices and online portals where staff can help with forms (but not give legal advice). The court system's Judicial Council forms are all available free at the California Courts website. Online services like Hello Divorce and It's Over Easy guide users through California-specific forms with prices ranging from a few hundred to a few thousand dollars depending on level of help.

For very limited cases — short marriages, no children, minimal assets — California offers Summary Dissolution, a streamlined process that doesn't require a court appearance. Both spouses must agree to it, and the eligibility rules are specific. See the Resources page for links.
