How to Get an Uncontested Divorce in King County?
If both spouses agree on everything about their divorce, they can file for an uncontested divorce in King County. This usually works best when there are no children under 18, no disagreements about property, and no requests for spousal support (money one spouse might pay the other after divorce).
To file for divorce in King County, at least one spouse must have lived in Washington State for at least 90 days before starting the process. This residency rule is explained in the Revised Code of Washington (RCW) 26.09.020, which covers divorce requirements in the state.
Here are the basic steps you need to take to get an uncontested divorce in King County:

Step 1. Fill Out the Divorce Forms.
- Get the right divorce forms, such as the Petition for Dissolution, Summons, and Financial Declaration, from the King County Superior Court website or in person at the King County Courthouse: 516 Third Avenue, Seattle, WA 98104
- Carefully read the instructions for each form to understand what’s needed.
- Fill out the forms by hand using black ink or type them on your computer – make sure your answers are honest and accurate.
- Sign all forms where required – don’t forget this step!
- Make at least three copies of your completed forms before filing – one for the court, one for your records, and one to serve your spouse.
Step 2. Serve Your Spouse.
- After you file your divorce papers with the court, you need to officially give copies of these papers to your spouse. This is called “serving” the papers.
- You cannot serve the papers yourself. Someone else who is over 18 and not involved in the case, like a friend, family member, or a professional process server, must do it for you.
- The person who serves the papers will fill out a form called “Proof of Personal Service” or “Proof of Service by Mail” to prove to the court that your spouse got the papers.
- Washington law says this process must follow rules in Superior Court Civil Rule 4 (CR 4) and RCW 4.28.080, which say how and when the papers must be served.
- You have 90 days after filing your divorce paperwork to serve your spouse.
- Keep a copy of the Proof of Service form for yourself and send a copy to the court to show you did this step.


Step 3. File Your Divorce Papers with the Court.
- After you fill out your forms and serve your spouse, you need to officially file these papers with the court to start your divorce case.
- The main forms you’ll file include the Petition for Dissolution, the Summons, and the Proof of Service (which shows your spouse was served).
- You can file your papers in person at the King County Courthouse:
516 Third Avenue, Seattle, WA 98104 - Or you can file online using King County’s e-filing system if you want to do it from home.
- There is a filing fee (usually about $280), but if money is tight, you can ask the court to waive the fee by filling out a simple form.
- Once your papers are filed, the court gives you a case number and tells you what happens next — this might include waiting a certain amount of time or filling out more forms.

To start a divorce in King County, you need to fill out and file some papers with the King County Superior Court. If your divorce is uncontested (meaning both spouses agree on everything), you can do this yourself by following Washington state court rules.
The main forms you’ll need are:
- Petition for Dissolution of Marriage (this is where you officially ask the court to end your marriage)
- Summons (this lets your spouse know the divorce case has started)
- Proof of Service (this shows the court that your spouse was given the papers)
You will usually pay a filing fee of about $280 when you turn in your forms. If you don’t have enough money to pay, you can ask the court to waive (skip) the fee by filling out a simple form.
Washington law says you have to wait at least 90 days after your spouse is officially served with the papers before the divorce can be finalized. Even if you agree on everything, the divorce isn’t official until the court signs the final order after this waiting period.
