How to File for Divorce in Washington State

Washington makes filing straightforward — no minimum residency period, no-fault grounds, and standardized court forms. But the process still takes a minimum of 90 days, requires mandatory financial disclosure, and involves decisions that affect your finances for decades. Here's what actually happens, step by step.

Step 1: Establish Jurisdiction

Washington has no durational residency requirement. You can file for divorce the day you move to the state, as long as you intend to make Washington your domicile. You don't need to prove you've lived here for six months or a year — establishing domicile is enough.

File in the Superior Court of the county where either spouse lives.

Step 2: File the Petition

You'll need three forms to start:

• Summons (FL Divorce 200) — notifies your spouse that dissolution proceedings have begun
• Petition for Dissolution (FL Divorce 201) — your request to the court to end the marriage
• Confidential Information Form (FL All Family 001) — personal identifiers filed under seal

The filing fee is $314 in most counties, though some counties (like King and Clark) add surcharges up to $400. If you can't afford it, Form FL All Family 012 (Fee Waiver) with a two-page financial statement may get the fee waived — eligibility is generally 125% of the federal poverty level.

Step 3: Serve Your Spouse

Your spouse must be formally served with the Summons and Petition. Options:

• Process server or sheriff ($40–$100)
• Service by mail with a signed acceptance (requires cooperation)
• Joinder — your spouse voluntarily joins the petition

After service, your spouse has 20 days to file a response (60 days if served out of state). You'll file a Proof of Personal Service (FL All Family 101) with the court.

Step 4: The 90-Day Waiting Period

Washington imposes a mandatory, non-waivable 90-day waiting period from the date the petition is both filed and served. No final decree can be entered before the 90 days expire — no exceptions, no judicial override.

This isn't idle time. Use it to:

• Complete mandatory financial disclosures (FL All Family 131)
• Gather supporting documents (tax returns, bank statements, pay stubs)
• Begin settlement negotiations
• Attend mandatory parenting education if you have children (county-specific requirements)

Step 5: Financial Disclosure

Both spouses must exchange comprehensive financial information during the waiting period. This includes:

• 3 years of federal income tax returns
• 6 months of consecutive pay stubs
• 12 months of bank and investment account statements
• Retirement and pension benefit statements
• Business financial statements if self-employed

Sensitive documents should be filed under Form FL All Family 011 (Sealed Financial Source Cover Sheet) to keep them out of the public record.

Step 6: Temporary Orders (If Needed)

If you need immediate financial protection or housing stability during the divorce, you can file for temporary orders using FL Divorce 223 (Motion) and FL Divorce 224 (Proposed Order). A motion filing costs $30–$60.

Temporary orders can address:

• Exclusive use of the family home
• Temporary spousal maintenance
• Temporary child support
• Restraining either spouse from dissipating assets

These orders stay in effect until the final decree replaces them.

Step 7: Negotiate or Litigate

Uncontested divorce. If both spouses agree on everything — property division, debts, spousal support, custody — you present your agreed-upon terms to the court. Many courts have a "pro se calendar" specifically for uncontested cases. This is the fastest and cheapest path.

Mediation. King County and Snohomish County require alternative dispute resolution (ADR) before setting a trial date. Even in counties that don't mandate it, mediation is significantly cheaper than trial. Mediators typically charge $150–$400/hour.

Contested trial. If you can't reach agreement, the case goes to a bench trial (no jury) in Superior Court. The judge makes final decisions on property division, spousal maintenance, and custody. Contested divorces typically take 6–18 months and cost $10,000–$50,000+ in attorney fees.

Step 8: Final Decree

Once all issues are resolved — by agreement or court order — the Findings and Conclusions (FL Divorce 235) and Decree of Dissolution (FL Divorce 236) are filed. The marriage is officially dissolved.

What Divorce Costs in Washington

A fully DIY uncontested divorce can cost as little as $314 (just the filing fee). Adding a mediator for a few sessions might bring the total to $1,500–$3,000. Full attorney representation in a contested case can easily exceed $25,000 per side.

Can You Do It Without a Lawyer?

Yes — Washington explicitly allows self-representation, and the court system provides standardized forms and self-help facilitators. A DIY approach works well when:

• The marriage is short (under 5 years)
• There's no real estate, business, or complex retirement assets
• Both spouses agree on the basic terms
• There are no children, or custody is already settled

For anything involving a family home, pensions, business interests, or significant spousal maintenance, professional guidance (even if just for document review) pays for itself.
