10 Washington Dissolution Mistakes to Avoid (2026)

Washington's dissolution process is relatively accessible, but these ten mistakes can create serious problems.

Mistake #1 — Filing an Individual Petition When You Could Co-Petition

If you and your spouse agree on everything, use the Joint Petition. It eliminates service, speeds up the timeline, and simplifies the process. Many filers default to individual petitions out of habit.

Fix: Check if a co-petition is an option before filing individually.

Mistake #2 — Not Understanding the 90-Day Clock

The 90-day waiting period starts from service date (individual petition) — not the filing date. Filing a week before service means 91+ days total.

Fix: Coordinate filing and service to start the 90-day clock as early as possible.

Mistake #3 — Failing to Address All Community Property in the Separation Contract

Washington community property includes all assets acquired during the marriage. Omitting an account, property, or debt from the Separation Contract leaves it unresolved — potentially requiring a post-dissolution motion.

Fix: Make a complete inventory of all assets and debts before drafting the Separation Contract.

Mistake #4 — Not Recording the Deed at the County Auditor

The Decree of Dissolution does not transfer real estate title. A new deed must be prepared, signed, notarized, and recorded at the county Auditor's office. Failing to do this leaves the leaving spouse on title.

Fix: Include a deed transfer deadline in the Separation Contract. Execute and record promptly after dissolution.

Mistake #5 — Skipping the QDRO for Retirement Accounts

The Separation Contract divides retirement accounts on paper. A QDRO is required to actually split employer plans (401k, pension). Without it, the intended recipient gets nothing from those accounts.

Fix: Engage a QDRO specialist promptly after the Decree is entered.

Mistake #6 — Vague Spousal Maintenance Terms

"Husband will pay wife a reasonable amount" is not enforceable. Maintenance provisions must specify the amount, start date, duration, and termination events.

Fix: Be specific. Or include a clear mutual written waiver.

Mistake #7 — Forgetting the Vital Statistics Form

Every Washington dissolution requires a Vital Statistics Form (similar to a "record of dissolution" form). Missing it can delay the Decree.

Fix: Include the Vital Statistics Form in your final submission packet.

Mistake #8 — Not Updating Beneficiary Designations

Retirement accounts and life insurance have beneficiary designations that may not automatically change at dissolution. Federal law governs ERISA plans — the divorce alone does not remove an ex-spouse as 401k beneficiary.

Fix: Update all beneficiary designations immediately after the Decree is entered.

Mistake #9 — Missing the Parenting Education Requirement

If you have minor children, both parents must complete a court-approved parenting education seminar before the Decree is entered. Missing this requirement delays the Decree.

Fix: Register for and complete the seminar early in the 90-day period.

Mistake #10 — Using Out-of-Date Forms

Washington court forms are updated periodically. Using an old form version can result in rejection.

Fix: Always download forms fresh from courts.wa.gov/forms immediately before filing.
