Divorce in San Diego runs through the Family Law Division of the San Diego Superior Court. If you live within the city of San Diego, your case is generally heard at the Central Courthouse at 1100 Union Street, downtown near Little Italy and the County Administration Center. The court assigns your case by residential ZIP code (SDSC Form ADM-254), so residents of outlying areas may be routed to the East County, North County, or South County regional courthouses instead. California is a no-fault, community property state under Family Code § 2310 and § 760, and every dissolution carries a mandatory six-month minimum waiting period under § 2339.

How do I file for divorce in San Diego, California?
To file for divorce in San Diego, you submit a Petition for Dissolution (Form FL-100) and a Summons (FL-110) to the San Diego Superior Court Family Law Division and pay the $435 filing fee. You then serve your spouse, who has 30 days to file a Response (FL-120). If you have minor children, you also file a Declaration Under UCCJEA (FL-105).
The full process moves through five stages: file the petition, serve your spouse, exchange Preliminary Declarations of Disclosure (Forms FL-140, FL-142, FL-150) within 60 days, negotiate or litigate the terms, and obtain a judgment. San Diego residents file at the Central Courthouse at 1100 Union Street, but you must confirm your assigned location using the court's ZIP code locator, because filing at the wrong courthouse delays your case. A venue declaration is required for every new family law filing. New for 2026, Senate Bill 1427 created a Joint Petition process (Form FL-700) that lets agreeing couples file together for a single $435 fee with no service of process, cutting total court costs from $870 to $435.
Where do I file for divorce in San Diego? (which courthouse)
San Diego city residents file at the Central Courthouse, 1100 Union Street, San Diego, CA 92101, the main family law filing location for downtown and central ZIP codes. The clerk's office operates Monday through Friday, 8:30 a.m. to 4:00 p.m., and the phone line is (619) 844-2777. The court routes cases by ZIP code, not by personal preference.
San Diego County operates four family law courthouses: the Central Courthouse downtown, the East County Regional Center at 250 East Main Street in El Cajon, the North County Regional Center at 325 South Melrose Drive in Vista, and the South County Regional Center at 500 Third Avenue in Chula Vista. Most divorces filed by residents inside the city of San Diego land at the Central Courthouse, which sits two blocks from the County Administration Center and is accessible via the MTS Blue and Green Line trolley at the County Center/Little Italy station. Use SDSC Form ADM-254 (the ZIP Code List) or the locator at sdcourt.ca.gov to confirm your assignment before you drive downtown.
How much does a divorce lawyer cost in San Diego?
A San Diego divorce lawyer generally charges $300 to $450 per hour and requests a retainer of $3,500 to $7,500 up front. An uncontested divorce with attorney assistance often totals $3,000 to $7,000, while a contested San Diego divorce commonly runs $20,000 to $30,000 once discovery, custody disputes, and trial preparation are factored in.
Your total cost depends on conflict, not city. The $435 court filing fee is fixed statewide under California's Statewide Civil Fee Schedule. Beyond that, the variables are attorney hours, whether you need a forensic accountant for business valuation, and whether custody is contested. Couples who agree on everything can use the 2026 Joint Petition (FL-700) and a flat-fee document service for under $1,500. Low-income filers can erase the $435 fee entirely with a fee waiver (Form FW-001) under Government Code § 68632 if they receive public benefits or fall below the income threshold.

How long does a divorce take in San Diego?
No San Diego divorce can be finalized in fewer than six months and one day from the date your spouse is served, under Family Code § 2339. This waiting period cannot be waived or shortened even if both spouses agree to every term. An uncontested case usually closes in 6 to 9 months; a contested case in San Diego often takes 12 to 30 months.
The six-month clock starts when the respondent is served the summons and petition, not when you file. During that window you can fully resolve property division, support, and parenting issues, but the court cannot terminate your marital status until the period expires. San Diego's family courts carry heavy caseloads, so hearing dates for contested motions can be set weeks out, extending timelines further. Couples who settle early and submit a complete judgment package (FL-180 and the marital settlement agreement) frequently get their default or uncontested judgment processed close to the six-month minimum.
What are the residency requirements to file in San Diego County?
To file for divorce in San Diego County, at least one spouse must have lived in California for six months and in San Diego County for three months immediately before filing the petition. These dual residency requirements are set by California Family Code § 2320 and are jurisdictional, meaning the court will reject a petition that does not meet them.
If you meet the six-month California requirement but not the three-month county requirement, you can file for legal separation first and amend to a dissolution once the county time is satisfied. Military families stationed at Naval Base San Diego, MCAS Miramar, or Coronado generally satisfy residency if either spouse has been stationed in California for six months and in San Diego County for three months. The petition (FL-100) requires you to state your residency dates under penalty of perjury, so keep documentation such as a lease, utility bills, or a California driver's license to confirm your San Diego County address if questioned.
How is property divided in a San Diego divorce?
San Diego courts divide marital property under California's community property rule in Family Code § 760, which presumes that everything acquired by either spouse during the marriage is owned 50/50. Separate property — assets owned before marriage, or received by gift or inheritance — stays with the original owner under § 770.
The community property presumption means a San Diego judge starts from an equal split of the marital estate, including home equity, retirement accounts, and business interests acquired during the marriage. Dividing a California pension or 401(k) requires a Qualified Domestic Relations Order; the Retirement QDRO Calculator can estimate the marital share. Real estate in a high-cost market like San Diego is often the largest asset, and spouses frequently choose between selling, buying out the other's share, or co-owning temporarily. Each spouse must disclose all assets and debts on Form FL-142 (Schedule of Assets and Debts); hiding assets can result in the court awarding 100% of the concealed asset to the other spouse.
How do custody and support work in San Diego?
San Diego family courts decide custody under the best-interests standard in California Family Code § 3011, weighing the child's health, safety, welfare, and any history of abuse. California uses the terms legal custody (decision-making) and physical custody (where the child lives), and courts favor frequent, continuing contact with both parents under § 3020.
Before a contested custody hearing, San Diego County requires parents to attend Family Court Services mediation, a mandatory step under the court's local rules aimed at reaching a parenting plan without trial. Child support follows California's statewide guideline formula, which factors each parent's income and the percentage of parenting time; estimate yours with the Child Support Calculator. Spousal support is need-based and, for marriages under 10 years, typically lasts about half the length of the marriage. For longer marriages the court retains jurisdiction indefinitely.
