Seattle Divorce Papers: Forms, Filing & Cost (2026)

If you're getting divorced in Seattle, the forms come from the Washington courts. They're free to download. They're also long and unforgiving — one missing signature can send the whole packet back from the clerk.

This guide walks through every form a Seattle divorce requires, where to get it, how to fill it out, and the most common mistakes that send a packet back from the King County Superior Court clerk.

The Seattle Divorce Paperwork Checklist

Every uncontested Seattle divorce uses the same core forms. The names vary by Washington statute, but the function is identical state to state:

• Petition for Dissolution of Marriage — the foundation document — identifies the parties, asserts Washington jurisdiction, states the no-fault ground, and asks the court to grant the divorce.

• Marital Settlement Agreement — the binding agreement between spouses covering property division, debts, support, and custody if children are involved. The court incorporates it into the final decree.

• Financial Disclosure Forms — Washington's mechanism to ensure full financial transparency between spouses before the court divides anything. Usually a sworn financial affidavit covering income, assets, debts, and expenses.

• Summons — the notice served on the responding spouse (skipped when filing jointly or with a waiver of service).

• Parenting Plan + Child Support Worksheet — required when minor children are involved. Spells out custody, parenting time, decision-making, and the calculated child support number.

• Proposed Decree of Dissolution of Marriage — the order the judge will sign at the end. You draft it; the court approves it.

Several Washington counties add local forms — typically a case information sheet, a notice regarding minor children, or an e-filing service contact form. The King County Superior Court clerk's office is the source of truth for what your specific case needs.

Where to Get Washington Divorce Papers

You can get the Washington divorce packet from three sources, in order of cheapest-to-most-convenient:

• The Washington courts website (free). Every required form is published as a fillable PDF. You'll need to identify the correct forms for your situation, download them, and fill them out yourself.

• The King County Superior Court self-help center (free). Many Washington courthouses staff a self-help clerk who can hand you a paper packet and answer non-legal questions about which forms apply.

• Online divorce services like Divorce.com™ (flat fee). The service prepares the entire packet from a guided questionnaire, so you never see a blank state form. Saves the most time; not free.

Skip random "free divorce forms" sites. They're often the wrong state, the wrong version, or missing the local addenda your county requires. The King County Superior Court bounces these back.

How to Fill Out Washington Divorce Papers

Washington divorce forms are unforgiving. The King County Superior Court will bounce back any packet with the wrong date format, a missing signature, or inconsistent financial figures. Some practical guidance:

• Use legal names, not nicknames. The name on the petition has to match the name on your marriage certificate and on every supporting document.

• State the Washington residency requirement on the petition. resident at filing (no minimum length). The petition typically requires a sworn statement that you meet it.

• Cite the no-fault ground. Washington is no-fault; the only ground is irretrievable breakdown. An uncontested filing should reference this language directly.

• Match dollar amounts across forms. The financial affidavit, settlement agreement, and (if applicable) child support worksheet should all reconcile — clerks check for this.

• Sign and date in front of a notary where required. Several forms — settlement agreements, financial affidavits — require notarized signatures. Don't sign in advance.

• Don't leave any field blank. Write "N/A" or "None" rather than skipping a question. Blanks are interpreted as incomplete forms.

Submitting Seattle Divorce Papers to the Court

Seattle divorce filings are processed through King County Superior Court. Washington accepts electronic filings through the Washington Courts e-filing portal for divorce cases, so you can submit the entire packet without setting foot in a courthouse.

• Filing fee: approximately $310–$320, paid at submission. Washington accepts fee waiver applications for filers under income limits.

• E-filing system: the Washington Courts e-filing portal. Most Washington counties now accept the full divorce packet electronically.

• Paper filing alternative: still available in most counties for filers who prefer to walk the packet into the clerk's office.

After You File: Service, Settlement, Decree

Once King County Superior Court accepts your packet, the case is officially open. From there:

• Service on the responding spouse — accomplished by Acceptance of Service (signed by the spouse), by sheriff, or by process server. Skipped entirely for joint petitions in counties that allow them.

• Washington waiting period — 90-day waiting period from filing and service. Used to finalize the settlement agreement and exchange any required financial disclosures.

• Submission of the signed settlement + proposed decree — after the wait expires. Most uncontested cases are decided on the documents without a hearing.

• Certified copies of the Decree of Dissolution of Marriage — issued by the clerk after the judge signs. Order multiple; you'll need them for DMV, banks, retirement accounts, and beneficiary updates.

Why Washington Divorce Papers Get Rejected

If your Washington divorce papers come back from the clerk, it's almost always one of these issues:

• Missing signature or notary block. The most common single rejection reason. Every signature line needs to be completed; notary stamps need to be present on forms that require them.

• Inconsistent financial figures. If the income on your financial affidavit doesn't match the income on the child support worksheet, the clerk will catch it.

• Using outdated form versions. State courts revise forms periodically. Always download from the official site within a few days of filing.

• Wrong court/wrong venue. Filings need to go to the correct Washington court for your county of residence. The King County Superior Court handles Seattle divorce cases.

• Incomplete settlement agreement. The agreement should resolve every issue — property, debts, support, custody (if applicable). Vague language gets bounced back.

• Wrong filing fee. Fees change. Check the current schedule at the clerk's office before submitting.
