What Does Divorce Cost in Washington?
Court filing fees, attorney rates, and what changes when both parties agree. Updated for 2026. These are estimates, not quotes.
The cost of a divorce in Washington depends almost entirely on one thing: whether both of you are reasonable. When you use SerenityNow to come to an agreement on property, support, and a parenting plan, most of the expense disappears. When you fight it out, attorney hours stack up fast. The two paths below show the difference honestly.

The figures on this page are general estimates drawn from published Washington court fee schedules and attorney rate surveys, and the child support estimate is illustrative. They are not legal or financial advice and they are not a quote for any specific case. The $500 SerenityNow fee covers document preparation for an uncontested filing where both parties are reasonable and use SerenityNow to come to an agreement, and does not include the court filing fee or any attorney representation. Actual costs vary by county and by the complexity of your situation. Child support estimates do not replace the official Washington calculation or the advice of a licensed attorney. Verify all figures with the Washington courts and a qualified professional before relying on them.
