San Diego divorce cost breakdown
The table below covers every major cost item you're likely to encounter. The range between the minimum and maximum is wide, because what you spend depends almost entirely on how much you and your spouse disagree — and on how you choose to resolve those disagreements.
| Cost item | Typical range | Notes |
|---|---|---|
| Filing fee (joint petition, SB 1427) | $870 total | One shared fee — $435 per petitioner. Paid when you file Form FL-700 with the San Diego Superior Court. |
| Filing fee (traditional petition + response) | $870 total | $435 to file the petition, $435 if the responding spouse files a response. Many uncontested cases use a Notice and Acknowledgment of Receipt instead of a formal response, keeping it at $435. |
| Service of process | $0 under SB 1427 | Traditional service runs $50–$100 via a process server or sheriff. Under the joint petition, filing itself counts as service. |
| San Diego mediator hourly rate | $300–$500/hr | Attorney-mediators trend toward the higher end. Most couples need 3–6 hours total. |
| Parent education class (if children involved) | $20–$60 | Required by San Diego Family Court Services when minor children are part of the case. |
| Attorney retainer | $3,500–$10,000+ | Replenished as hours are billed at $350–$550/hr. Not required for uncontested or mediated cases. |
| QDRO (retirement account division) | $500–$2,500 | Required if a 401(k), pension, or other retirement account is being divided. Prepared by a specialist attorney or plan administrator. |
| Real estate appraisal | $600–$1,200 | Often needed to establish fair market value when dividing a home. San Diego's high home values make this a higher-stakes line item. |
| Total: uncontested or mediated | $870–$8,000 | Depends on whether you use a mediator and how many sessions it takes. |
| Total: contested with attorneys | $15,000–$40,000+ | Per side. High-asset or high-conflict cases can exceed this significantly. |
Fee waivers are available for those who qualify based on income or public assistance. If you can't afford the $870 filing fee, ask the San Diego Superior Court clerk for a Request to Waive Court Fees (Form FW-001) at the time you file.
The 2026 joint petition advantage in San Diego
The most significant change to California divorce law in a generation took effect on January 1, 2026. Senate Bill 1427 allows any married couple who agrees on all terms to file for divorce jointly, using Form FL-700, instead of the traditional adversarial petition-and-response model.
What SB 1427 means for your San Diego divorce cost
Under the traditional process, one spouse files a petition (FL-100) and formally serves the other — a step that costs $50–$100 and adds time and friction. The responding spouse then typically files a response for another $435. Under SB 1427, both spouses sign Form FL-700 together. The filing itself constitutes service on both parties, so there's no process server, no sheriff's fee, and no adversarial opener to the process.
The joint petition is available to any couple — including those with children, long marriages, and significant assets — as long as both spouses agree to resolve all issues cooperatively. Either spouse can revoke the joint petition at any time by filing Form FL-720, at which point the case converts to a standard dissolution.
Hello Divorce supports the SB 1427 joint petition process. If you and your spouse are on the same page, this is the most efficient and least costly way to start your San Diego divorce. You can learn more about the full step-by-step process in our guide to e-filing your California divorce paperwork.
What drives cost up in San Diego
San Diego is a high-cost-of-living county. The median home value hovers near $900,000, and many households carry a mix of military pensions, stock compensation, investment properties, and significant retirement accounts. Each of those asset types adds complexity — and cost — to a divorce.
Conflict and attorney hours
The single biggest cost driver in a San Diego divorce is disagreement. Every contested issue — custody, spousal support, property division — requires attorney time billed at $350–$550 per hour. A case that heads to trial can easily generate $50,000 or more in combined legal fees. The more you and your spouse can agree before engaging attorneys, the less you'll spend.
High-value real estate and the Moore-Marsden calculation
If one spouse owned a home before marriage and community funds paid down the mortgage during the marriage, the community may have earned a proportional interest in any appreciation. This is called the Moore-Marsden doctrine, and it's a recurring issue in San Diego divorces given local home price appreciation over the past decade.
Property note
A Moore-Marsden calculation requires documentation of the original purchase price, down payment source, community mortgage payments, and current market value. If these records are incomplete or disputed, a forensic accountant may be needed — adding $2,000–$5,000 or more to your cost. Our guide to property and debt division in California covers how separate property and community claims are evaluated.
Military pensions and retirement accounts
San Diego has one of the largest active-duty military populations in the country. Military pensions, TSP accounts, and other federal retirement benefits have their own division rules separate from civilian QDROs. Dividing them correctly requires a specialist and adds $500–$2,500 or more to the process. If a military pension is part of your divorce, budget for this from the start.

What is the filing fee to start a divorce in San Diego County?
The filing fee is $435 per person at the San Diego Superior Court. If both spouses file jointly under SB 1427 (Form FL-700), the total is $870 — one $435 fee for each petitioner. If one spouse files a traditional petition and the other files a formal response, the total is also $870. Fee waivers are available for those who qualify based on income or public assistance eligibility.
How much does an uncontested divorce cost in San Diego in 2026?
An uncontested divorce in San Diego typically costs $870–$3,500. The court filing fee alone is $870 (using the joint petition under SB 1427). Add document preparation and an online divorce service and you may pay $1,500–$2,500 total. Using a private mediator for a few sessions typically brings the total to $3,500–$8,000 depending on the complexity of your assets and whether children are involved.
What is SB 1427 and how does it affect divorce cost in San Diego?
SB 1427 is a California law, effective January 1, 2026, that allows any couple who agrees on all divorce terms to file a joint petition using Form FL-700. Because both spouses sign and file together, the filing itself counts as service on both parties — eliminating the $50–$100 cost of formal service of process. It also removes the adversarial opener to the divorce, which can lower overall legal costs by reducing conflict from the start. Any married couple can use the joint petition, including those with children, long marriages, and significant assets.
How long does a divorce take in San Diego, and does timeline affect cost?
California law requires a mandatory six-month waiting period from the date of filing before a divorce can be finalized. This period cannot be waived. The minimum timeline is therefore about six months for an uncontested divorce. Contested cases often take 12–18 months or longer, and every additional month of litigation means additional attorney fees. The fastest and most affordable divorces are those where both spouses reach full agreement early and file the joint petition under SB 1427.
Does San Diego have any local rules that add to divorce costs?
Yes. San Diego County requires a Family Law Certificate of Assignment (Form SDSC D-49), which you must file along with your initial petition to confirm you're filing in the correct courthouse location based on your zip code. Cases involving minor children also require both parents to complete a court-approved parent education class, which typically costs $20–$60. San Diego Family Court Services provides mandatory mediation for custody disputes at no cost, which can actually reduce private mediation expenses in cases involving children.
San Diego County court resources
San Diego County has four family law filing locations. Use the courthouse that serves your residential zip code and bring a completed Family Law Certificate of Assignment (Form SDSC D-49) with your initial filing.
