Filing for divorce in Washington is the start of a legal process that affects your home, finances, parenting schedule, support obligations, and long-term stability.
In Washington, divorce is legally called a dissolution of marriage. According to RCW 26.09.030, Washington is a no-fault divorce state, which means the court can grant a divorce when the marriage is “irretrievably broken” without requiring either spouse to prove misconduct.
That legal rule is the trunk of the process. Everything else branches from it, like where you file, how your spouse is served, when the 90-day waiting period starts, how property is divided, how parenting plans are created, and how final orders are entered.
Since 2014, Northwest Family Law has handled Seattle divorce cases involving complex property concerns such as Amazon stock options, Microsoft bonuses, Boeing pensions, and startup equity.
Filing connects to service. Service connects to deadlines. Deadlines connect to temporary orders. Temporary orders connect to children, money, and housing. Financial disclosure connects to property division, support, and settlement leverage. A strong divorce strategy keeps all of those branches connected from the beginning.
Quick Answer: How Do You File for Divorce in Washington?
To file for divorce in Washington, one spouse files a Petition for Dissolution of Marriage in Superior Court, serves the other spouse, waits at least 90 days after filing and service, resolves property, debt, parenting, and support issues, and then asks the court to enter final divorce orders.
According to RCW 26.09.030, a Washington court cannot enter a divorce decree until at least 90 days have passed after the petition is filed and the summons is served or the respondent joins the petition.

According to the CDC’s National Center for Health Statistics, Washington’s divorce rate was 2.7 divorces per 1,000 people in 2023. According to the CDC’s national marriage and divorce data, the U.S. divorce rate was 2.4 per 1,000 people in 2023 across 45 reporting states and D.C.
Step 1: Confirm That You Can File for Divorce in Washington
The first step of the divorce process is jurisdiction, which means the court’s authority to hear your case.
You can usually file for divorce in Washington if one spouse lives in Washington or is stationed in Washington as a member of the armed forces. According to RCW 26.09.030, a spouse may petition for dissolution when the court has proper jurisdiction and the marriage is irretrievably broken.
This step matters because the county and court where you file can affect forms, local rules, hearing schedules, mediation expectations, and case timelines.
Step 2: Decide Whether the Divorce Is Contested or Uncontested
The next step is case type. A divorce can be uncontested, contested, or partially contested.
An uncontested divorce means both spouses agree on major issues, including:
- Property division
- Debt division
- Parenting plan
- Child support
- Spousal maintenance
- Final divorce terms
A contested divorce means at least one issue remains unresolved. Contested cases often involve children, the family home, retirement accounts, business interests, hidden assets, high income, or equity compensation.
According to Washington Courts, 2025 case data showed 8,097 uncontested or resolved-when-filed cases and 7,136 settled or agreed judgments, compared with 874 court decisions after trial commencement. That means many cases resolve by agreement, but the quality of the agreement depends on preparation and legal strategy.
Step 3: Prepare the Required Divorce Forms
The step connects the legal case to the court system. Filing the wrong forms, missing required documents, or skipping local requirements can delay the case.
Common Washington divorce forms may include:
- Petition for Divorce
- Summons
- Confidential Information Form
- Certificate of Dissolution
- Proof of Personal Service
- Financial Declaration
- Parenting Plan, if children are involved
- Child Support Worksheets, if children are involved
- Temporary Order forms, if immediate relief is needed
According to Washington State Courts, divorce forms are available through the statewide court form library, but local courts may require additional forms or local-rule compliance.
Step 4: File the Petition in Superior Court
The filing branch starts the formal court case.
Divorce cases in Washington are filed in Superior Court. You usually file in the county where you or your spouse lives. Once the petition is filed, the case exists, but the timeline does not fully move forward until the other spouse is served or joins the petition.
For Seattle-area cases, King County Superior Court handles family law matters. According to King County Superior Court, the court has family law forms and procedures for divorce, custody, and related family law cases.
Step 5: Serve Your Spouse
Service is one of the most important steps because it connects filing to deadlines.
After filing, your spouse must receive the divorce papers through proper legal service unless they sign a joinder or acceptance of service. You generally cannot just email, text, or verbally tell your spouse and assume service is complete.
According to Washington Law Help, a spouse usually has 20 days to respond if served in Washington, 60 days if served outside Washington, and 90 days if served by mail or publication.
This is where many people misunderstand the 90-day waiting period. The waiting period is tied to filing and service. Filing alone is not enough if the other spouse has not been properly served or joined the case.
Step 6: Use the 90-Day Waiting Period Strategically
The 90-day waiting period is not dead time. It is the planning step of the divorce process.
During this period, spouses may:
- Exchange financial records
- Negotiate settlement terms
- Work on a parenting plan
- Calculate child support
- Request temporary orders
- Prepare for mediation
- Resolve property and debt issues
- Identify whether professional valuation is needed
For simple uncontested cases, the 90-day period may be enough time to prepare final orders. For contested cases, it is only the minimum starting point.
Step 7: Request Temporary Orders if You Need Stability During the Case
Temporary orders connect the pending divorce to real life. They create rules while the case is still open.
Temporary orders may address:
- Who lives in the home
- Temporary parenting schedule
- Temporary child support
- Temporary spousal maintenance
- Bill payment
- Vehicle use
- Restraining orders
- Protection from asset transfers
- Use of bank accounts or personal property
Spouses can ask for temporary orders while the divorce is pending when they need court rules before final orders are entered.This step is especially important in high-conflict divorces, cases involving children, or cases where one spouse controls most of the money.
Step 8: Exchange Financial Information
Without accurate financial information, it is difficult to divide property, calculate support, assess settlement offers, or identify whether one spouse is hiding income or assets.
Financial disclosure may involve:
- Pay stubs
- Tax returns
- Bank statements
- Retirement account statements
- Credit card statements
- Mortgage documents
- Business records
- Stock plans
- RSU records
- Bonus documentation
- Debt records
- Separate property records
In Washington divorces, this branch can become more intricate because income may include more than salary. Northwest Family Law notes that many local divorce cases may involve Amazon stock options, Microsoft bonuses, Boeing pensions, and startup equity, which require detailed review and valuation before settlement.
Step 9: Understand How Washington Divides Property and Debt
Property division is one of the largest branches of a Washington divorce.
Washington is a community property state, but that does not mean every asset is automatically divided 50/50. Washington courts divide property and liabilities in a way that is just and equitable after considering factors such as community property, separate property, the length of the marriage, and each spouse’s economic circumstances.
The important connection is that financial disclosure feeds property division. If the disclosure is incomplete, the property division may be unfair, inaccurate, or vulnerable to future disputes.
Step 10: Create a Parenting Plan if You Have Children
When children are involved, the parenting plan becomes the central step of filing for divorce.
Washington does not frame parenting disputes only as “custody battles.” The court focuses on parental responsibilities, residential schedules, decision-making, and the child’s best interests.
A parenting plan usually addresses:
- Where the child lives
- Weekday and weekend schedules
- Holidays
- School breaks
- Transportation
- Decision-making authority
- Dispute resolution
- Travel
- Communication
- Safety restrictions, if needed
Step 11: Calculate Child Support
Child support connects income, parenting time, the child’s needs, and Washington’s support schedule.
For 2026, this section needs to be especially current. Changes to the Washington State Child Support Schedule went into effect on January 1, 2026, including an updated Economic Table with monthly income amounts adjusted to a minimum of $2,200 and a maximum of $50,000.
Child support may also involve:
- Health insurance
- Daycare
- Uninsured medical costs
- Educational expenses
- Long-distance transportation
- Deviation requests
- Imputed income
- Post-secondary support
Step 12: Negotiate, Mediate, or Prepare for Trial
Settlement is the resolution step. Most cases do not need a full trial, but every case should be prepared as if the outcome matters, because it does.
That does not mean trial is unimportant. It means strong preparation often creates better settlement leverage. A spouse who understands property values, child support exposure, parenting risks, and court standards is less likely to accept a bad agreement.
Mediation or negotiation may resolve:
- Parenting schedules
- Child support
- Spousal maintenance
- Home sale or refinance
- Retirement division
- Business valuation
- Debt division
- Tax issues
- Attorney fee issues
Northwest Family Law describes its Washington divorce approach as combining legal precision, emotional insight, long-term planning, proactive communication, and white-glove legal care, according to the firm’s Washington family law page.
Step 13: Finalize the Divorce
Final orders are the root system that remains after the divorce is complete. They control what happens next.
Final divorce orders may include:
- Final Divorce Order
- Findings and Conclusions
- Parenting Plan
- Child Support Order
- Order of Child Support Worksheets
- Property and Debt Division
- Spousal Maintenance Order
- Restraining Order, if applicable
- Name Change Order, if requested
Once the judge signs and enters the final orders, the marriage is legally dissolved.
Common Mistakes When Filing for Divorce in Washington
Avoid these mistakes:
- Filing without understanding the 90-day waiting period
- Serving your spouse incorrectly
- Assuming Washington always divides everything 50/50
- Signing final orders before reviewing all financial information
- Forgetting about retirement accounts, RSUs, bonuses, or business interests
- Moving out without a parenting strategy
- Ignoring temporary orders
- Using outdated child support numbers
- Treating an uncontested divorce as risk-free
- Posting about the divorce online
- Agreeing to vague parenting language
- Failing to account for tax or refinance issues
Do You Need a Divorce Lawyer to File in Washington?
You can file for divorce without a lawyer. But the more branches your case has, the more risk there is in handling it alone.
Legal help is especially important if your case involves:
- Children
- A home
- Retirement accounts
- Spousal maintenance
- Business ownership
- High income
- Stock options or RSUs
- Domestic violence
- Relocation
- Hidden assets
- A spouse who already has a lawyer
The risk is not just making a filing mistake. The bigger risk is signing final orders that do not protect your children, finances, or future.
