Divorce in San Francisco: what you need to know in 2026
Filing for divorce in San Francisco means working with the Unified Family Court at the Civic Center Courthouse. The filing fee here is $450 per party, slightly above the statewide rate due to a local surcharge. Under California's 2026 joint petition law (SB 1427), couples who agree on terms can file together using Form FL-700, splitting one fee and skipping formal service entirely.
Quick answer
To file for divorce in San Francisco, you must have lived in California for six months and in San Francisco County for three months. You file at the Civic Center Courthouse, 400 McAllister Street. San Francisco's filing fee is $450 per party, slightly higher than the statewide rate. Under SB 1427, effective January 1, 2026, couples who agree on all terms can use Form FL-700 to file jointly, share one $450 fee, and avoid formal service altogether.
Where to file: San Francisco's Unified Family Court
All divorce and family law cases in San Francisco are handled by the Unified Family Court, located inside the Civic Center Courthouse. This is where you file your initial paperwork, attend hearings, and submit your final judgment.
| Detail | Information |
|---|---|
| Courthouse name | Civic Center Courthouse, Unified Family Court |
| Address | 400 McAllister Street, Room 402, San Francisco, CA 94102 |
| Filing fee (petition) | $450 per party (includes local surcharge) |
| Joint petition fee (SB 1427) | $450 shared by both spouses |
| Mandatory waiting period | 6 months from date of service (cannot be waived) |
| Residency requirement | 6 months in California; 3 months in San Francisco County |
| E-filing | Required for family law dissolution cases |
San Francisco's $450 filing fee is $15 higher than the statewide rate of $435, due to a courthouse construction surcharge authorized under state law. That applies to each party, so a traditional contested divorce carries a combined $900 in filing fees. The 2026 joint petition cuts that to a single $450 payment shared between spouses.
Local rules that affect your case
California family law is statewide, but San Francisco has a few local rules and practices you should know before you file.
Mandatory e-filing for dissolution cases
San Francisco designates family law dissolution cases as e-filing cases under its local rules. This means you submit paperwork electronically through the court's approved filing system rather than walking in with paper copies. Hello Divorce prepares your forms so they're ready to e-file.
Mandatory mediation for custody disputes
If your divorce involves minor children and you cannot agree on a parenting plan, San Francisco Superior Court requires mediation through its Unified Family Court mediation program before a judge will hear the dispute. Mediation sessions are confidential and focus on reaching a workable plan for both parents. If you reach an agreement, it becomes part of your court order. If not, the case moves to a hearing.
High-value real estate considerations
San Francisco is one of the most expensive real estate markets in the country. If your home was purchased before marriage, or if community funds were used to pay down the mortgage on a separate-property home, the Moore-Marsden calculation may apply to determine what share of any appreciation belongs to the community. This is a specialized analysis that often requires a forensic accountant or real estate appraiser. Hello Divorce's California property division guide explains how this works in detail.
2026 update: Piqui's Law applies in all California custody cases
SB 331, known as Piqui's Law, now requires California family court judges who evaluate custody cases to complete training on domestic violence and child abuse. This applies to all San Francisco custody proceedings.
If domestic violence is part of your situation, this change is relevant to how your case will be handled. Speak with a Hello Divorce attorney or schedule your free call for guidance specific to your circumstances.
The 2026 joint petition advantage
California's most significant divorce law change in years took effect January 1, 2026. SB 1427 allows spouses who agree on all terms to file a joint petition for dissolution using Form FL-700, rather than having one spouse file and then formally serve the other.
In San Francisco, this means the joint filing fee is $450, split between both spouses, rather than the $900 combined cost of a traditional petition plus response. There's no process server to hire, no proof of service to file, and no 30-day response deadline for the other spouse to worry about.
Who qualifies for the joint petition
Both spouses must agree to file together and must be in agreement on the terms of the divorce, including property division, support, and any parenting plan. If your situation involves significant disagreement, domestic violence, or hidden assets, the traditional petition process may be the more appropriate path. A Hello Divorce attorney can help you assess which route fits your circumstances.
Hello Divorce supports the full FL-700 joint petition process, including preparation of all supporting financial disclosure forms. You can learn more in our California divorce laws guide, which covers SB 1427 in full detail, or explore how uncontested divorce works in California for more context on the amicable process.

How long does a divorce take in San Francisco?
The minimum timeline is six months from the date your spouse is served with divorce papers, or from the date a joint petition is filed under SB 1427. That waiting period is set by California law and cannot be waived by either party or by the court. Uncontested divorces where both parties agree on all terms can be finalized close to that six-month mark. Contested cases involving disputed property, support, or custody can take 12 to 36 months or longer, depending on the complexity of the issues and San Francisco's court caseload.
What is the filing fee for divorce in San Francisco?
San Francisco charges $450 per party to file for divorce, which is $15 higher than the statewide rate of $435 due to a local courthouse construction surcharge. In a traditional divorce, both spouses pay separately: $450 to file the petition and $450 for the response, totaling $900. Under the 2026 joint petition law (SB 1427), both spouses file together and share a single $450 fee. If you cannot afford the filing fee, you may qualify for a fee waiver by completing Form FW-001 with the court clerk.
Do I have to go to court for my San Francisco divorce?
Not necessarily. Many uncontested divorces in San Francisco are resolved without either spouse appearing in person before a judge. Once the paperwork is complete, submitted, and the waiting period has passed, the court clerk can enter the judgment by default. If there are contested issues, such as disagreements over property, support, or custody, court hearings become necessary. Custody disputes in San Francisco also trigger mandatory mediation before a judge will decide.
Can I file for divorce online if I live in San Francisco?
Yes. San Francisco requires e-filing for family law dissolution cases, which means your paperwork is submitted electronically. Hello Divorce prepares all the required forms, including the new FL-700 joint petition under SB 1427, and formats them so they are ready for the San Francisco Superior Court's e-filing system. You handle the entire process from home, without visiting the courthouse, for most uncontested cases.
