California Now Allows Joint Divorce Petitions Under SB 1427, Effective January 1, 2025
California couples who agree on ending their marriage can now file a single joint petition for dissolution under Senate Bill 1427, which took effect January 1, 2025. This landmark change eliminates the requirement for formal service of process, potentially saving couples $500 or more in filing and service fees while cutting weeks off the divorce timeline. Unlike summary dissolution, the new joint petition process has no restrictions on marriage length, children, or property values.

Why This Matters for California Divorces
This change represents the most significant procedural reform to California divorce law since the state pioneered no-fault divorce in 1970. Before SB 1427, even couples who completely agreed on every term of their divorce were required to follow an adversarial process: one spouse filed as the petitioner, the other was served as the respondent, and both paid separate filing fees.
The traditional process cost a minimum of $435 for the initial filing fee plus $435 for the response fee, totaling $870 in court costs alone. Add professional service fees of $75-$150, and even the most amicable California divorce started at nearly $1,000 before any attorney involvement.
Under the new joint petition framework established by SB 1427, couples file a single petition together with a combined filing fee. The Los Angeles Superior Court confirmed implementation began January 1, 2025, with new forms available through all California Superior Courts.
How California's Joint Petition Differs from Summary Dissolution
California already had an expedited divorce option called summary dissolution, but that process came with strict eligibility requirements under Cal. Fam. Code § 2400. Summary dissolution was only available to couples who met all of the following criteria:
- Married less than 5 years
- No children together (born or adopted during marriage)
- No real property ownership
- Less than $47,000 in community property
- Less than $47,000 in separate property claims
- Waived spousal support
These restrictions meant that approximately 85% of divorcing California couples were ineligible for summary dissolution. A couple married 6 years, or a couple with a modest family home, or parents of minor children all had to use the traditional adversarial petition-and-response process.
SB 1427's joint petition option has none of these restrictions. Couples with children, real estate, retirement accounts, and lengthy marriages can all file jointly, provided they agree on the terms of their dissolution. This opens streamlined divorce to the vast majority of amicable California couples who were previously locked out of expedited processes.
The Six-Month Waiting Period Still Applies
One thing SB 1427 does not change is California's mandatory 6-month waiting period under Cal. Fam. Code § 2339. Even with a joint petition, the earliest a California divorce can be finalized is 6 months and 1 day from the date the petition is filed with the court.
This waiting period serves as a cooling-off window, giving couples time to reconsider or address any issues that arise during the dissolution process. The 6-month clock starts when the joint petition is filed, not when any subsequent agreements are reached.
However, the joint petition process can still be faster overall because couples skip the 30-day response period that applies to traditional dissolutions, and they avoid potential delays from failed service attempts or disputes about proper notice.
Practical Requirements for Filing a Joint Petition
To use California's new joint petition process, couples must meet specific procedural requirements established by the Judicial Council of California:
- Both spouses must sign the joint petition simultaneously or within a short window
- The petition must include a complete marital settlement agreement or property division
- If minor children exist, a parenting plan addressing custody and support must be attached
- Both parties must complete required financial disclosures under Cal. Fam. Code § 2104
- The filing must be submitted to the Superior Court in the county where either spouse resides
California residency requirements still apply. At least one spouse must have lived in California for 6 months and in the filing county for 3 months before filing, per Cal. Fam. Code § 2320.
Cost Comparison: Traditional vs. Joint Petition Divorce in California
The financial benefits of joint petition filing become clear when comparing total costs:
Traditional contested or semi-contested dissolution:
- Initial petition filing fee: $435
- Response filing fee: $435
- Service of process: $75-$150
- Minimum total court costs: $945-$1,020
Joint petition dissolution:
- Single joint filing fee: $435
- Service of process: $0 (not required)
- Total court costs: $435
This represents a minimum savings of $510 to $585 in court-related fees alone. Couples who would have hired attorneys to handle service complications or response filings may save significantly more. The Los Angeles Superior Court estimates the streamlined process could reduce overall divorce costs by 30-50% for couples who qualify.
What This Means for California Residents Considering Divorce
-
Evaluate whether you and your spouse agree on all major terms before filing — the joint petition requires complete consensus on property division, support, and custody
-
Gather financial documents early, as both spouses must still complete full financial disclosures under Cal. Fam. Code § 2104 regardless of filing method
-
Consider mediation if you agree on most issues but have a few unresolved questions — a mediator can help you reach the full agreement needed for joint filing
-
Understand that the 6-month waiting period cannot be waived, so filing sooner starts that clock sooner
-
Consult with a California family law attorney to ensure your marital settlement agreement addresses all required elements and protects both parties' interests
Frequently Asked Questions
Can couples with children use California's joint petition process?
Yes, couples with minor children can use the joint petition process under SB 1427. Unlike summary dissolution, which prohibited couples with children from filing, the new joint petition has no restrictions based on children. Parents must include a complete parenting plan addressing custody, visitation schedules, and child support calculations when they file their joint petition with the court.
How much money will we save by filing a joint petition instead of a traditional divorce?
California couples save a minimum of $510-$585 by filing jointly. Traditional divorce requires a $435 petition fee plus a $435 response fee plus $75-$150 for service of process, totaling approximately $945-$1,020. Joint petition filing costs only $435 total and eliminates service of process entirely. Couples who avoid attorney fees for service-related issues may save considerably more.
Do we still need to wait 6 months for our divorce to be final with a joint petition?
Yes, California's mandatory 6-month waiting period under Cal. Fam. Code § 2339 applies to all dissolutions including joint petitions. Your divorce cannot be finalized until 6 months and 1 day after filing. However, the joint petition may result in a faster overall timeline because you skip the 30-day response period and avoid delays from service of process complications.
What if we agree on most things but not everything — can we still file jointly?
No, the joint petition process requires complete agreement on all terms at the time of filing. If you agree on most issues but have unresolved disputes about property division, support, or custody, you must either resolve those issues through mediation or negotiation before filing jointly, or use the traditional petition-and-response process while you work through the remaining disagreements.
Which California courts are accepting joint petition filings?
All 58 California Superior Courts began accepting joint petition filings on January 1, 2025. The Judicial Council released standardized forms statewide, so the process is identical whether you file in Los Angeles, San Francisco, San Diego, or any other California county. You must file in a county where at least one spouse has resided for a minimum of 3 months.
