Effective January 1, 2026, California SB 1427 allows any married couple to file a single joint petition for divorce using Form FL-700, eliminating service of process and the petitioner-versus-respondent structure. This expands a procedure once limited to couples married under five years with no children or property, giving roughly 100,000 California couples who divorce annually a non-adversarial filing option.

Why this matters legally
SB 1427 fundamentally changes how California spouses initiate a divorce by removing the structural assumption that one spouse sues the other. Before January 1, 2026, the joint-petition option under California's summary dissolution rules was restricted to couples married fewer than five years with no children, no real property, and limited debts and assets. The new law, authored by Senator Ben Allen and reported by CalMatters, strips away those eligibility limits.
The practical legal effect is significant. In a traditional California divorce, one spouse files a petition and must formally serve the other under Cal. Fam. Code § 2331, starting a 30-day response clock. A joint petition removes that step entirely. Both spouses are co-petitioners from day one, which means there is no respondent to serve, no default risk for missing a response deadline, and no procedural label casting one party as the initiator and the other as the defendant. For couples who already agree to end the marriage, this reduces conflict, cost, and the emotional weight of being formally sued by a spouse.
How California law handles this
California remains a no-fault, community-property state, and SB 1427 changes the procedure for filing — not the substantive rules for dividing property or determining support. Under Cal. Fam. Code § 2310, the only grounds for dissolution are irreconcilable differences or permanent legal incapacity, so neither spouse must prove wrongdoing. Community property acquired during marriage is still divided equally under Cal. Fam. Code § 760, and the mandatory six-month waiting period before a judgment becomes final under Cal. Fam. Code § 2339 still applies to joint petitions.
What the joint petition changes is the entry point and the procedural posture. Couples file one Form FL-700 together rather than a Petition (FL-100) and Response (FL-120). Critically, the law builds in an off-ramp: either spouse can revoke the joint petition and convert the case to a standard contested or default proceeding by filing Form FL-720, and doing so preserves the original filing date. That protection matters because the filing date can affect the date of separation analysis and the six-month clock. The disclosure obligations also remain intact — both spouses must still exchange preliminary and final declarations of disclosure under Cal. Fam. Code § 2104, so the joint-petition route does not let either party skip financial transparency.
Practical takeaways
If you and your spouse are considering divorce in California in 2026, here is how SB 1427 affects your options:
-
Decide whether a joint petition fits your situation. The joint petition works best when both spouses agree the marriage is over and are willing to cooperate on next steps. If there is significant disagreement, domestic violence, or an imbalance of power, a standard petition with its built-in service and response protections may serve you better.
-
Use Form FL-700 to file together. Both spouses sign and file a single Joint Petition for dissolution, which eliminates the need to serve the other party and avoids the petitioner/respondent labels.
-
Know your exit option. Either spouse can revoke the joint petition at any time by filing Form FL-720, converting the matter to a standard case. You do not lose your original filing date when you convert.
-
Complete your financial disclosures. Filing jointly does not waive the mandatory disclosure of assets, debts, income, and expenses required under Cal. Fam. Code § 2104. Gather pay stubs, tax returns, account statements, and a debt list early.
-
Plan for the six-month minimum. Even an agreed joint petition cannot be finalized before the six-month waiting period under Cal. Fam. Code § 2339 runs from the date the case begins.
-
Get tailored advice on property and support. The procedure is simpler, but community-property division, spousal support, and any custody arrangements still carry the same legal weight. A consultation can confirm whether your agreement protects your long-term interests.
California's joint divorce petition is a meaningful step toward a less adversarial process, but a simpler filing form does not make the underlying decisions simpler. If you are weighing whether a joint petition is right for your circumstances, connecting with a California family law attorney can help you understand how these new procedures apply to your assets, your children, and your timeline.
