Residency requirement:
Washington has no minimum durational residency requirement. You can file for divorce as long as you or your spouse is a resident of Washington, or either of you is a member of the armed forces stationed in the state, at the time the petition is filed (RCW §26.09.030). There is no required number of days, weeks, or months of residency before filing.
Filing fee:
$300–$400
Waiting period:
Washington uses the Washington State Child Support Schedule (RCW §26.19) to calculate child support based on the combined monthly net income of both parents, the number of children, and the residential schedule. Starting in 2026, updated guidelines under Engrossed House Bill 1014 expand the child support table to cover combined monthly incomes up to $50,000 and increase the self-support reserve for low-income parents to 180% of the federal poverty level.

Ending a marriage of 20, 25, or 30+ years in Washington carries significant financial implications that shorter marriages do not face. Under RCW 26.09.090, courts recognize marriages exceeding 20 years as "long-term" and apply different standards for spousal maintenance, often awarding indefinite support rather than rehabilitative payments. Washington divides all property—both community and separate—under a "just and equitable" standard per RCW 26.09.080, with marriage duration serving as a primary factor. For couples divorcing after two or more decades, retirement accounts, pensions, and Social Security benefits become critical assets requiring careful division strategies.

What Qualifies as a Long-Term Marriage in Washington

Washington courts classify marriages lasting 20 to 25 years or longer as "long-term marriages" for purposes of spousal maintenance and property division under RCW 26.09.090. This classification triggers heightened scrutiny of economic disparities between spouses and often results in indefinite maintenance awards rather than time-limited rehabilitative support. Courts recognize that both parties contributed to household income during extended marriages, even when one spouse managed domestic responsibilities rather than earning wages.

The 20-year threshold carries particular significance because it affects three major divorce outcomes: spousal maintenance duration, property division proportions, and retirement benefit calculations. A marriage of 19 years and 11 months may receive substantially different treatment than one lasting 20 years and 1 month, particularly regarding Social Security derivative benefits which require exactly 10 years of marriage.

Washington judges have broad discretion under the dissolution statute to consider marriage length as a factor in every financial decision. The longer a marriage lasted, the more likely courts will award substantial maintenance, divide separate property, and ensure both spouses can maintain roughly equivalent post-divorce lifestyles. This reflects Washington's policy that long-married couples have created economic partnerships deserving of equitable dissolution rather than clean-break separation.

Spousal Maintenance for Long-Term Marriages

Spousal maintenance in Washington divorce cases involving marriages of 20+ years follows different patterns than shorter marriages under RCW 26.09.090. Courts frequently award indefinite maintenance to the lower-earning spouse, particularly when that spouse sacrificed career advancement to support the household or the higher-earning spouse's career. Washington has no statutory formula for maintenance amounts or duration, giving judges substantial discretion based on six statutory factors including marriage duration, standard of living, and each spouse's financial resources.

Informal practitioner guidelines suggest that marriages lasting 25 years or more often result in indefinite maintenance, while mid-length marriages of 10-25 years typically receive maintenance lasting approximately one year for every three to four years of marriage. For a 24-year marriage, this could mean 6-8 years of maintenance payments, though courts may extend this indefinitely based on circumstances.

Six Statutory Factors Courts Must Consider

Under RCW 26.09.090, Washington courts evaluate spousal maintenance using six mandatory factors that shape both the amount and duration of support awards:

  1. Financial resources of the spouse seeking maintenance, including separate property and the portion of community property awarded in the divorce
  2. Time necessary to acquire sufficient education or training to find appropriate employment
  3. Standard of living established during the marriage
  4. Duration of the marriage or domestic partnership
  5. Age, physical and emotional condition, and financial obligations of the spouse seeking maintenance
  6. Ability of the paying spouse to meet their own needs and financial obligations while paying maintenance

For marriages exceeding 20 years, factor four (duration) heavily influences outcomes. Courts recognize that a spouse who spent two decades supporting a household may face insurmountable barriers to achieving financial independence through employment alone, particularly if they are over 50 years old at divorce.

Types of Maintenance Awards

Washington courts issue four categories of spousal maintenance, with long-term marriages typically involving the latter two:

Maintenance TypeTypical DurationCommon in Long Marriages
TemporaryDuring divorce proceedings onlyYes (standard)
Rehabilitative2-5 years for education/trainingSometimes
Long-term5-15 years or indefiniteVery common
DisabilityIndefinite if spouse cannot workWhen applicable

The goal in long-term marriage dissolution is to place both parties in roughly equal financial positions post-divorce. This means a spouse who earned $200,000 annually during marriage while their partner stayed home may owe maintenance that equalizes both parties' post-divorce incomes for an extended period or indefinitely.

2024 Wilcox Decision Impact

The Washington Supreme Court's 2024 Wilcox decision clarified that while courts must consider a requesting spouse's need for support among the six statutory factors, a finding of absolute need is not a prerequisite to awarding maintenance. This ruling expanded potential maintenance awards for spouses in long-term marriages who may have some income or assets but face substantial economic disparity compared to the higher-earning spouse.

Property Division in 20+ Year Marriages

Washington divides all marital property—both community and separate—under the "just and equitable" standard established in RCW 26.09.080. Despite common assumptions, Washington law does not mandate a 50/50 split. Courts consider four statutory factors: the nature and extent of community property, the nature and extent of separate property, the duration of the marriage, and each spouse's economic circumstances at the time of division.

For marriages lasting 20+ years, property accumulated during the relationship typically constitutes the vast majority of both spouses' wealth. Washington presumes that all property acquired during marriage is community property belonging equally to both spouses, regardless of whose name appears on titles or accounts. This includes wages, real estate purchased during marriage, retirement contributions, business interests developed during marriage, and investment gains.

Community Property vs. Separate Property

Washington recognizes two property categories, though courts can divide both in a dissolution:

Property TypeDefinitionTreatment in Long Marriage
Community PropertyAssets acquired during marriagePresumed 50/50 ownership; divided equitably
Separate PropertyPre-marriage assets, gifts, inheritancesMay be awarded to owning spouse or divided if equitable
Commingled PropertySeparate property mixed with communityOften treated as community property

In long-term marriages, separate property often becomes commingled with community assets over decades, making separation difficult or impossible. Washington courts may award one spouse's separate property to the other spouse if equitable under the circumstances—a power unique to community property states.

The Family Home

Under RCW 26.09.080, courts specifically consider the desirability of awarding the family home—or the right to live there temporarily—to the spouse with whom children primarily reside. For long-term marriages where children are adults, courts evaluate whether one spouse can afford to maintain the home independently, whether refinancing is feasible to remove the other spouse from the mortgage, and whether selling and dividing proceeds is more equitable.

A home purchased for $150,000 twenty-five years ago may now be worth $800,000 or more, representing substantial equity requiring careful division. Courts may order the home sold with proceeds split, award the home to one spouse with an offsetting payment to the other, or allow one spouse to remain temporarily with a future buyout or sale date.

Retirement Accounts and Pension Division

Retirement assets often represent the second-largest asset in long-term Washington divorces after the family home. Under community property rules, the portion of any 401(k), pension, IRA, or other retirement account contributed during the marriage constitutes community property subject to division. For a 25-year marriage where one spouse built a $800,000 pension entirely during the marriage, approximately $400,000 belongs to each spouse.

The Coverture Formula

Washington courts apply the coverture formula to determine the community property portion of retirement accounts when employment spans periods both inside and outside the marriage. The formula divides months married during plan participation by total months of service. For a pension with 30 years of service where 20 years overlapped with the marriage, 66.7% constitutes community property.

Example: A teacher's pension worth $4,000 monthly at retirement, accumulated over 30 years with 24 years during marriage, would yield approximately $3,200 monthly as community property (24/30 = 80%), with each spouse entitled to roughly $1,600 monthly.

QDRO Requirements

Dividing most employer-sponsored retirement plans requires a Qualified Domestic Relations Order (QDRO) that directs the plan administrator to pay benefits to the non-employee spouse. The divorce decree alone does not transfer retirement rights—you must obtain a QDRO that complies with both federal law and the specific plan's rules.

Plan TypeDivision MethodSpecial Considerations
Private 401(k)/403(b)QDRO requiredMust meet ERISA requirements
Private PensionQDRO requiredSurvivor benefits must be addressed
IRATransfer incident to divorceNo QDRO needed; transfer tax-free
Washington PERS/TRS/SERSRCW 41.50.670 orderMaximum 75% to former spouse; file within 90 days
Federal PensionCourt Order Acceptable for ProcessingOPM has specific format requirements
Military RetirementMilitary court order10/10 rule for direct payment

Washington state government pensions administered by the Department of Retirement Systems (DRS) require statutory property division orders under RCW 41.50.670 rather than QDROs. DRS limits payments to former spouses at 75% maximum of the member's periodic retirement benefit. Orders must be filed with DRS within 90 days of court entry to preserve rights.

Present Value vs. Future Division

Couples can divide retirement assets using two methods. The first calculates present value through actuarial analysis, allowing one spouse to receive the retirement account while the other receives offsetting assets like home equity. The second uses a QDRO to divide benefits at retirement, with each spouse receiving their share when the employee retires. Long-term marriages often benefit from the QDRO method when retirement is imminent.

Social Security Benefits for Long-Term Marriages

The 10-year marriage rule provides divorced spouses access to derivative Social Security benefits that can substantially impact retirement planning. If your marriage lasted at least 10 years before divorce, you may claim benefits equal to up to 50% of your ex-spouse's Primary Insurance Amount without reducing their benefits at all.

Eligibility Requirements

To claim divorced spouse Social Security benefits, you must meet all of the following criteria:

  1. Your marriage lasted at least 10 years (from wedding date to divorce finalization)
  2. You are currently unmarried
  3. You are at least 62 years old
  4. Your ex-spouse is eligible for Social Security retirement benefits
  5. Your own benefit based on your work record is less than 50% of your ex-spouse's benefit

The 10-year requirement is strictly enforced—a marriage lasting 9 years and 364 days does not qualify. Social Security counts from your wedding date to the date your divorce was legally finalized.

Benefit Amounts and Strategy

Divorced spouse benefits equal up to 50% of your ex-spouse's Primary Insurance Amount (PIA) if you claim at your full retirement age. Claiming earlier reduces benefits, while waiting past full retirement age does not increase divorced spouse benefits. Importantly, your ex-spouse cannot prevent you from claiming these benefits, and your claim does not reduce their payments.

ScenarioBenefit AmountNotes
Claim at 62~32.5% of ex-spouse's PIAPermanently reduced
Claim at Full Retirement Age50% of ex-spouse's PIAMaximum divorced spouse benefit
Ex-spouse diesUp to 100% of their benefitDivorced survivor benefits apply

If you remarry, you generally cannot receive benefits on your former spouse's record unless the new marriage ends through death, divorce, or annulment. Divorced survivors can receive 71.5% to 100% of the deceased ex-spouse's benefit amount depending on claiming age.

Strategic Timing Considerations

For spouses approaching the 10-year marriage threshold, delaying divorce finalization by even a few months can mean the difference between receiving Social Security benefits of $1,500 monthly versus $0. If you are at 9 years and 8 months of marriage, postponing the divorce filing or extending negotiations may be financially advantageous.

Washington's No-Fault Divorce System

Washington is a purely no-fault divorce state under RCW 26.09.030. The only ground for dissolution is that the marriage is "irretrievably broken." Neither spouse needs to prove fault such as adultery, abandonment, or abuse. Courts will not consider marital misconduct when dividing property or awarding maintenance.

This means a spouse who cheated throughout a 25-year marriage faces the same property division and maintenance analysis as a spouse who remained faithful. While emotionally difficult for the wronged spouse, Washington's no-fault system typically results in faster, less expensive divorces than fault-based states.

Residency Requirements

Washington has one of the most flexible residency requirements in the nation. Under RCW 26.09.030, you must simply be a Washington resident with intent to remain at the time of filing—there is no minimum duration requirement. Courts interpret "resident" as "domiciliary," combining physical presence with intent to make Washington your permanent home.

Military members stationed in Washington satisfy the residency requirement even if their legal domicile is another state. However, if your spouse lives outside Washington, the court may have limited personal jurisdiction over them for property division and support orders.

The 90-Day Waiting Period

Washington imposes a mandatory 90-day waiting period between filing the petition for dissolution and entry of the final decree under RCW 26.09.030. This period begins when the petition is both filed and served on the responding spouse. The 90 days cannot be waived regardless of how amicable the divorce or how urgent the circumstances.

For long-term marriages with substantial assets, 90 days is rarely sufficient to negotiate property division, maintenance, and retirement account allocation. Most contested long-term marriage divorces take 12-18 months from filing to finalization.

Filing for Divorce After 20+ Years: Process Overview

Filing for divorce in Washington after a long-term marriage follows standard dissolution procedures, but the complexity of accumulated assets, retirement accounts, and maintenance calculations typically extends timelines and increases costs.

Filing Steps and Costs

  1. Prepare the Petition: Complete the Petition for Dissolution of Marriage (FL Divorce 201)
  2. File with Superior Court: Filing fees range from $314 to $364 depending on county (as of March 2026; verify with your local clerk)
  3. Serve Your Spouse: Professional service typically costs $50-$100
  4. 90-Day Waiting Period: Begins upon service
  5. Discovery and Negotiation: Exchange financial documents, negotiate settlement
  6. Trial or Settlement: Most cases settle; contested trials add significant time and expense
  7. Final Decree: Court enters Decree of Dissolution
Cost CategoryTypical RangeLong Marriage Considerations
Filing Fee$314-$364Same regardless of marriage length
Service of Process$50-$100Same regardless of marriage length
Attorney Fees$15,000-$50,000+Higher due to asset complexity
Mediation$3,000-$10,000Recommended for settlement
Expert Witnesses$2,000-$15,000Business valuators, actuaries for pensions
QDRO Preparation$500-$2,500Required for retirement division

Fee Waivers

If you cannot afford the filing fee, submit a Fee Waiver Request form with income documentation showing household income at or below 125% of federal poverty guidelines ($19,406 for a single person or $39,750 for a family of four in 2026).

Protecting Your Interests in a Long-Term Marriage Divorce

Divorcing after 20+ years requires careful attention to assets that may have been accumulated over decades. The following strategies help protect your financial interests:

Financial Documentation

Gather complete financial records before filing, including tax returns for the past 3-5 years, all bank and investment account statements, retirement account statements showing contribution history, real estate deeds and mortgage documents, business financial statements if applicable, and documentation of any separate property claims.

Retirement Asset Protection

Do not cash out or transfer retirement accounts without court approval or agreement. Early withdrawals trigger 10% penalties plus income taxes, destroying significant value. A $500,000 401(k) withdrawn improperly could net only $300,000 after 37% combined federal and state taxes plus the 10% penalty.

Temporary Orders

Request temporary maintenance and restraining orders early in the process. Washington courts can issue orders preventing either spouse from transferring or concealing property, depleting accounts, or changing beneficiaries. These orders preserve the status quo while divorce proceedings continue.

Frequently Asked Questions

How long does divorce take after 20+ years of marriage in Washington?

Washington requires a minimum 90-day waiting period from filing and service before finalizing any divorce under RCW 26.09.030. However, long-term marriages with substantial assets typically take 12-18 months to resolve through settlement negotiation. Contested cases going to trial may extend to 24 months or longer due to the complexity of retirement account division, business valuations, and maintenance calculations.

Will I receive alimony after a 20-year marriage in Washington?

Spousal maintenance after a 20+ year marriage is very likely if there is significant income disparity between spouses under RCW 26.09.090. Courts frequently award indefinite maintenance for marriages exceeding 20-25 years, particularly when one spouse sacrificed career advancement for household responsibilities. The amount depends on six statutory factors including standard of living during marriage, each spouse's financial resources, and the paying spouse's ability to pay while meeting their own needs.

How is a house divided after 25 years of marriage?

Washington courts divide the family home equitably under RCW 26.09.080, not necessarily 50/50. Common outcomes include selling the home and splitting proceeds, one spouse buying out the other's interest, one spouse receiving the home with offsetting assets to the other, or temporary continued residence until children graduate or a set future date. A home purchased for $200,000 twenty-five years ago now worth $750,000 represents $550,000 in equity requiring careful allocation.

Can I get Social Security from my ex-spouse after divorce?

Yes, if your marriage lasted at least 10 years, you are currently unmarried, age 62 or older, and your own benefit is less than 50% of your ex-spouse's benefit. You can receive up to 50% of your ex-spouse's Primary Insurance Amount without reducing their benefits. A marriage of 9 years and 11 months does not qualify—the 10-year requirement is strictly enforced by counting from wedding date to divorce finalization date.

How are retirement accounts divided in a Washington divorce?

Retirement contributions made during marriage are community property divided equitably under RCW 26.09.080. Courts apply the coverture formula (months married during plan participation divided by total service months) to determine the community portion. A QDRO is required for most employer plans; Washington state pensions require orders under RCW 41.50.670 filed within 90 days. The community portion is typically split 50/50, though courts may vary percentages based on other factors.

What happens to the pension after a long marriage divorce?

Pensions earned during a 20+ year marriage are largely community property subject to division. A pension accumulated entirely during a 25-year marriage would typically be divided 50/50, with each spouse receiving half of the monthly benefit when the employee retires. Washington state pensions limit former spouse payments to 75% of the member's benefit. You can choose current offset (one spouse keeps pension, other gets equivalent assets) or future division (both receive payments at retirement).

Is fault considered in Washington divorce property division?

No. Washington is a purely no-fault divorce state under RCW 26.09.030. Courts cannot consider adultery, abandonment, or other marital misconduct when dividing property or awarding maintenance. The only exception involves dissipation of assets—if one spouse wasted community funds on affairs, gambling, or other improper purposes during separation, courts may credit the other spouse for dissipated amounts.

How much does divorce cost after 20 years of marriage in Washington?

Filing fees range from $314 to $364 depending on county. Total costs for long-term marriage divorces typically range from $15,000 to $75,000+ including attorney fees, expert witnesses (business valuators, pension actuaries), mediation, and QDRO preparation. Uncontested divorces where spouses agree on all terms may cost $5,000-$15,000 in attorney fees. Contested divorces going to trial commonly exceed $50,000 per spouse.

Can spousal maintenance be modified after the divorce is final?

Yes, unless your divorce decree expressly states that maintenance is non-modifiable. Under RCW 26.09.170, Washington allows modification when the requesting party demonstrates a substantial change in circumstances that is material, non-voluntary, and not foreseeable at the time of the original order. Common grounds include job loss, disability, retirement, or significant income changes for either party.

What if my spouse hides assets during a long-term marriage divorce?

Washington courts take asset concealment seriously. Request formal discovery including interrogatories, document requests, and depositions to trace all assets. Forensic accountants can analyze financial records for hidden accounts, unreported income, or transferred assets. Courts may impose sanctions, award attorney fees, or divide hidden assets entirely to the wronged spouse. Temporary restraining orders can prevent transfers during proceedings.
