Starting a Divorce in California: First Steps, Paperwork, and Process Options

Divorce is not only a court case. It is also a set of decisions about finances, property, support, parenting, and a family’s transition. That is why a form-by-form checklist is useful—but incomplete.

Start by separating two different maps

The first map is the legal case sequence. The California Courts describe four broad stages: start the case, share financial information, make decisions, and finalize the divorce. These steps apply regardless of whether the spouses resolve issues themselves, with professional help, or in court.

The second map is the process used to reach decisions. Common options include self-management, traditional legal representation, mediation, and collaborative divorce. These are not four different court systems. They are different ways to organize information, advice, negotiation, and decision-making within the larger legal process.

The legal sequence

California’s divorce process has four broad stages

The official California Courts self-help site is the best starting point for current procedural instructions. Its divorce roadmap organizes a case into these stages:

1. 01

   Start the case

   One spouse files and has the papers served, or eligible spouses may use California’s joint-petition process. Filing begins the legal case; it does not decide every issue.

2. 02

   Share financial information

   Both spouses exchange required information about income, expenses, property, and debt. This disclosure step is separate from negotiating a final agreement.

3. 03

   Make decisions

   The spouses may reach an agreement, a case may proceed by default, or a judge may decide issues the spouses cannot resolve.

4. 04

   Finalize the divorce

   The court must receive the correct final forms and sign a judgment. A California divorce cannot become final sooner than six months after the required starting event.

A minimum waiting period is not the same as a promised finish date. The time a case actually takes depends on service, disclosures, the issues involved, agreement, court schedules, and whether required paperwork is complete.

Before the first form

Ask questions the paperwork cannot answer for you

Filing starts a legal process and can set deadlines and restrictions in motion. Before choosing a process—or assuming you must choose only one—consider:

• Safety and coercive control. Can each person participate and make decisions freely? Is there an immediate need for protection, financial restraint, custody orders, or another urgent court response?
• The decisions ahead. What must be decided about property, debt, support, children, housing, insurance, taxes, or a business?
• Access to reliable information. Can both spouses identify and exchange complete financial and parenting information?
• Ability to negotiate. Can both people speak, listen, ask questions, and disagree without intimidation or retaliation?
• Complexity and professional support. Are there issues that call for legal advice, financial analysis, property valuation, tax guidance, or family expertise?
• Family goals. What kind of working relationship will be needed after the divorce, particularly if there are children?
• Time, privacy, and budget. Which tradeoffs matter most, and what resources are realistically available?

Paperwork orientation

Know what the first forms do—and what they do not do

In a regular California divorce, the person starting the case commonly prepares a Petition—Marriage/Domestic Partnership (FL-100) and a Summons (FL-110), along with any local or child-related forms that apply. The other spouse must receive formal notice through legally valid service; the filing spouse cannot personally serve the papers.

The Petition tells the court basic information and what the filing spouse may ask the court to order. It does not, by itself, divide property, establish a complete parenting plan, or produce a final divorce judgment.

California generally requires preliminary financial disclosures early in the case. The California Courts instructs each spouse to exchange the required disclosure documents and to file proof that the exchange occurred. The financial documents themselves are generally shared with the other spouse rather than filed with the court.

The decision-making map

Four common ways to get support and reach decisions

No option is automatically best for every family, and it is not unusual for people to use more than one kind of support. The useful comparison is not simply “Which one is cheapest?” It is “How will information, advice, negotiation, safety, and final decisions be handled?”

California’s court system recognizes that spouses may reach an agreement, proceed by default, or ask a judge to decide. The California Courts decision guide explains those legal routes. The four options above help describe how people may prepare for and move through those decisions.

What this guide cannot tell you

General information is not an individual recommendation

This guide cannot tell you whether to file, which forms apply to your facts, whether an emergency order is needed, what an appropriate settlement would be, or which process is safe and suitable for your family. It is educational information, not legal, financial, tax, or mental-health advice.
