A joint petition is a request that parties file together to seek court action. In family law, spouses or registered domestic partners may use an available joint procedure to start a divorce, dissolution, or legal separation together. The practical question is what that filing changes: who signs, whether initial service is needed, what still must be disclosed, and how the case proceeds if agreement breaks down.

California introduced its ordinary joint-petition process on January 1, 2026. It allows parties who agree, or plan to agree, on every issue to begin together. They do not need a finished settlement when they file. They do need a complete agreement to finish through that process. Filing jointly does not itself end a marriage or domestic partnership. The California Courts joint-petition guide explains this distinction.

Joint Petition, Uncontested Divorce, and Summary Dissolution

These terms describe different things. Joint filing identifies how a case starts; agreement or disagreement concerns how its issues are resolved. California’s ordinary joint process is also different from its narrower summary-dissolution procedure.

Term or procedure

Main distinction

Practical consequence

Ordinary joint petition in California

Both parties start with FL-700 and FL-710, intending to resolve all issues by agreement

Further disclosures, a written agreement, and judgment papers remain necessary

Uncontested divorce

The issues are resolved by agreement rather than a judge deciding a dispute

A case can become agreed after an ordinary petition and response; “uncontested” does not mean filing alone completes it

Contested divorce

One or more issues require the court to decide between competing positions

An ordinary California joint case must change procedure if a party requests court orders before judgment

California summary dissolution

A separate, simplified route with restrictive qualifications

Check its own rules and forms, including FL-800; do not import its restrictions into FL-700

California’s summary-dissolution eligibility guide covers requirements involving marriage length, children, property, debt, and waiver of spousal support. A couple who fails those requirements may still be able to use the ordinary joint process. Having children or substantial property does not, by itself, bar an ordinary joint petition.

Who Can Use California’s Ordinary Joint Process?

Check these points before signing:

The official FL-700-INFO instructions caution that this process may not be suitable where there has been domestic violence or a protective order. They also explain that a person can seek a domestic-violence restraining order whether or not a divorce is filed. Do not let the desire to file jointly delay asking the court about protection or independent legal help.

California Filing, Disclosure, and Judgment Steps

  1. Prepare the starting forms. Complete FL-700 and Summons—Joint Petition, FL-710. List the issues you intend to resolve. If there are minor children together, each party must complete and sign the applicable FL-105 custody-jurisdiction declaration. Choose Petitioner 1 and Petitioner 2 consistently. On later forms using “Petitioner” and “Respondent,” those correspond to Petitioner 1 and Petitioner 2.
  2. File in the proper court. The state guide calls for an original and two copies of the starting forms. Check the county court’s filing location, local requirements, and whether e-filing is available. Pay the applicable fees or seek a fee waiver. If both parties need waivers, each applies separately; ask the clerk how partial eligibility affects the fees.
  3. Understand what starts immediately. Under Family Code section 2331(b), filing the joint petition and joint summons completes initial service and constitutes both parties’ appearance. There is no separate initial response to wait for. Read FL-710’s automatic restraining orders, including its rules and exceptions concerning children, property, and insurance. They apply from filing. This initial service rule does not eliminate later disclosure or notice requirements.
  4. Exchange financial disclosures. Both joint petitioners generally must serve preliminary disclosures within 60 days of filing. Section 2104 permits a written agreement or court order extending the statutory periods. The packet includes FL-140, FL-150, and FL-142 or FL-160, with supporting financial information. Each party files FL-141 to show service. The preliminary disclosure and tax-return packet is exchanged, not routinely filed with the court; that does not mean every financial form is exempt from filing. FL-700-INFO separately directs filing FL-150. Check the requirements for each form and request. Follow current service instructions rather than treating joint filing as a waiver of disclosure.
  5. Finish the agreement and request judgment. Resolve every issue in writing, then submit the agreement with the required judgment documents. The basic forms include FL-130, FL-170, proposed Judgment FL-180, and Notice of Entry of Judgment FL-190. Final financial disclosures must be completed unless properly waived under section 2105; FL-144 records the qualifying mutual waiver. Waiving final disclosures is not permission to skip preliminary disclosures or conceal information. Children and support can require additional documents and review.

The court provides separate judgment checklists without minor children and with minor children. A signed settlement alone is not the final judgment. Missing disclosure proof, incomplete attachments, or unresolved terms can prevent the court from processing the final papers.

Property and retirement need more than an “amicable” label. Identify the actual accounts, debts, values, and proposed division. For retirement benefits, ask about the plan’s order requirements and the tax consequences before transferring money. The IRS retirement-and-divorce explanation notes that many plans require a qualified domestic relations order, or QDRO, before paying benefits to a former spouse. Filing FL-700 is not itself that order or a resolution of those account-specific questions.

What If One Person Changes Their Mind?

Before judgment is entered, either party can revoke California’s ordinary joint process without the other party’s permission or advance court approval. Revocation changes the procedure; it does not dismiss the case.

The steps are consequential:

Under Family Code section 2342.5, a party seeking a pre-judgment request for order, including a discovery motion, or a trial setting must file the amended pleading before or at the same time as that request. Parties may seek discovery while proceeding jointly, but asking the judge for an order brings this procedural consequence. Automatic orders in FL-710 are different from a new request for temporary support or custody orders.

Illustrative decision point: Riley and Morgan intend to negotiate custody and divide a pension. Unfinished negotiations alone do not mean a California joint filing is unavailable. But if Riley needs the court to decide temporary custody before judgment, the regular joint process cannot simply continue unchanged: the revocation/amended-pleading procedure applies. Neither these invented facts nor a willingness to cooperate establishes what custody or pension division the court should approve.

Other States and Other Legal Contexts

Do not use California’s forms as a nationwide filing map. Nevada’s court-issued joint-divorce instructions, for example, call for a full agreement and notarized signatures, a resident-witness affidavit, and submission of a proposed decree. They also warn about rights waived, including appeal. That differs from California’s ability to start while planning to agree. Check the relevant state and county instructions before choosing a packet.

The phrase also appears outside family law. Under 11 U.S.C. section 302, an eligible individual and that individual’s spouse may commence a joint bankruptcy case through a single petition. That federal bankruptcy procedure has its own requirements; it is not a joint divorce filing.

Common Questions About Joint Petitions

How long does a joint petition take in California? FL-700-INFO explains that the earliest divorce date is six months and one day after joint filing. This is a minimum timing rule, not a processing promise. The court still must enter judgment, and incomplete papers or unresolved issues can take longer. Legal separation has no corresponding six-month waiting period, but still needs a judgment and does not end the marriage or partnership.

What is the first thing to do? Identify your state, county, legal relationship, requested outcome, and whether both people intend to resolve every issue by agreement. Check residency and whether immediate court orders are needed before signing the joint packet. Gather financial records early so the disclosure stage is not overlooked.

Is there an advantage to being the person who files first? For California’s joint form, FL-700 expressly says there is no legal advantage to being Petitioner 1 rather than Petitioner 2. That does not establish that timing, jurisdiction, or protective needs never matter in a different filing situation. Choose the correct procedure rather than assuming the label decides the outcome.

What mistake should we avoid? Treating a cooperative start as a completed divorce. Keep three checkpoints separate: the filed opening papers, the exchanged financial information and complete agreement, and the court’s judgment. If agreement or safety changes, address the procedural consequences instead of ignoring deadlines or assuming the initial filing protects every interest.
