How this divorce cost estimator works
The calculator does only the arithmetic described below. It cannot resolve disputed facts, calculate tax liability, choose a county’s procedure, or predict what a judge will decide. Use it to see how a changed input affects the number and what needs outside help.
How the cost total is built
Court entry fees+Service+Professional work+Case expenses
The total begins with one selected first-paper fee. You supply the service amount, attorney hours and rate, mediation, and other professional costs. The defaults are placeholders, not market averages or quotes. Change the court-fee input when budgeting a joint petition or both spouses’ first papers.
Court fees in 2026
A petition or first response costs $435–$450
| Court context | Current example | Planning note |
|---|---|---|
| Most Superior Courts | $435 | One party’s petition or first appearance |
| Riverside and San Francisco | $450 | A local courthouse-construction surcharge raises the total |
| Amount loaded on this page | $435 | Edit it if your court or case path differs |
| Responding spouse | $435–$450 | A response or other first appearance generally has its own fee |
Service, e-filing provider charges, motions, copies, records, lawyers, mediation, experts, trial deposits, and implementation work are outside the first-paper amount. The filing fee alone says little about what the whole case will cost.
Where the budget grows
The disputed work usually costs more than entering the courthouse
Fewer hours spent on disputes
Filing, service, disclosures, drafting, and judgment work remain. If a lawyer offers limited-scope or flat-fee help, use that quote instead of the hourly placeholder.
More work outside the filing fee
Temporary orders, discovery, custody issues, valuation, tracing, experts, mediation, and trial preparation can become the main expense.
What the total includes
Price the work your case is likely to need
Included here
- One selected first-paper amount
- Service
- Attorney hours and rate
- Mediation
- Other professional costs
Add if your case needs it
- A response, motion, custody surcharge, or e-filing charge
- A custody evaluation or child-related professional
- Forensic accounting, tracing, appraisal, or valuation
- Depositions, transcripts, records, or trial expenses
- Retirement orders, deeds, title work, refinancing, or enforcement
Attorney fees are simply the hours entered multiplied by the entered rate. Replace the defaults with the court’s fee and provider quotes as soon as you have them.
If court fees are unaffordable
Form FW-001 asks the court to waive specified charges
The March 2026 form provides three routes: a listed public benefit, household income below the current table, or inability to pay court fees while meeting basic needs. The judge decides the request, and later changes in finances can affect an approved waiver.

Common questions
What California law says about this calculation
How much does it cost to file for divorce in California?
California Courts lists a $435–$450 filing range. Most counties charge $435 for a petition or the respondent's first paper. Riverside and San Francisco total $450. San Bernardino remains $435 because its local construction surcharge is offset in the 2026 fee appendix.
Does the other spouse also pay a filing fee?
Usually. A respondent who files a response or another chargeable first appearance generally pays the same first-paper amount, unless the court grants a fee waiver. Someone who never appears and is defaulted ordinarily does not pay a response fee.
Can California divorce filing fees be waived?
Yes. Form FW-001 allows a request based on listed public benefits, household income below the current table, or inability to pay court fees while covering basic household needs. The judge decides whether the applicant qualifies.
How long must someone live in California before filing?
For an ordinary divorce, one spouse must have lived in California for the previous six months and in the filing county for the previous three months. California-registered domestic partnerships and some same-sex marriages performed in California have different jurisdiction rules.
Is a California divorce final six months after filing?
No. In a regular case, six months from service or the respondent's appearance is only the earliest date marital status can end. The court must still sign a judgment, and missing paperwork or unresolved issues can keep the case open longer.
What usually drives the total cost of a California divorce?
The filing fee is often a small part of the total. Cost grows with attorney time, temporary-order hearings, discovery, custody disputes, real-estate or business valuation, separate-property tracing, retirement orders, mediation, experts, trial preparation, and the work required to carry out the judgment.
