Marriage Details
Enter 0–100 years
Enter a past date
Marriage less than 5 years? ℹ️Marriages under 5 years typically result in no long-term maintenance. Temporary or short rehabilitative support only.
Marriage 25+ years? ℹ️Washington uses a 25-year threshold (not 20) for long-term marriage. Indefinite maintenance is possible for marriages of 25+ years under RCW 26.09.090.
Is recipient custodial parent?
Washington-Specific Factors
Domestic violence involved? ℹ️Washington courts may increase maintenance 10-20% and extend duration when domestic violence is a factor. Protective orders can also affect temporary support calculations.
Washington Domestic Violence Impact:
10–20% increase in maintenance amounts typically awarded
May qualify for longer duration regardless of marriage duration
Court may order additional therapy/rehabilitation costs
Protective orders can affect temporary support calculations
Fault-based divorce? ℹ️Washington is primarily a no-fault divorce state. Per In re Marriage of Mattson (1999), marital misconduct generally does not affect maintenance except in extreme cases of economic misconduct.
Washington Fault Considerations:
Washington is primarily no-fault: Fault rarely affects maintenance
Extreme cases: Egregious economic misconduct may be considered
Hiding assets or intentional unemployment may affect awards

Important Legal Note — Recent Changes: Under the Washington Supreme Court’s August 2024 decision in In re Marriage of Wilcox (No. 102401-1), a spouse seeking maintenance does NOT need to prove financial “need” as a prerequisite. Courts have broad discretion to award maintenance to achieve economic fairness between parties. Additionally, effective January 1, 2026, Washington’s Child Support Economic Table has been substantially expanded (EHB 1014) with an income cap of $50,000/month.

Washington Maintenance Case Law
⚠ LANDMARK: Need Is Not a Prerequisite for Maintenance
In re Marriage of Wilcox, No. 102401-1 (Wash. 2024)
The Washington Supreme Court held that a spouse seeking maintenance does NOT need to prove financial “need” as a prerequisite. While courts must consider need along with other statutory factors, need is just one factor among equals. The court’s paramount concern is the parties’ economic conditions post-dissolution. Maintenance is a flexible tool to achieve economic fairness, not merely to cover bare necessities.
Standard of Living & Ability to Pay
In re Marriage of Washburn, 101 Wn.2d 168 (1984)
Established that maintenance should be based on need and ability to pay, with consideration of the standard of living established during the marriage. Though predating Wilcox, the standard-of-living factor remains central to RCW 26.09.090 analysis.
Professional Degrees — Not Property, But Economically Relevant
In re Marriage of Bulicek, 59 Wn. App. 630 (1990)
Held that professional degrees and licenses are not property subject to division, but the economic advantage from such education may be considered in maintenance calculations, including continuing education costs and professional expenses.
Cohabitation Requires Proof of Changed Financial Needs
In re Marriage of Rink, 18 Wn. App. 549 (1977)
Established that cohabitation alone does not automatically terminate maintenance. The payor must petition the court and prove that the cohabitation has changed the recipient’s financial needs through financial interdependence.
No-Fault State — Misconduct Generally Irrelevant
In re Marriage of Mattson, 95 Wn. App. 592 (1999)
Confirmed that Washington is primarily a no-fault divorce state and marital misconduct generally does not affect maintenance awards, except in extreme cases of egregious economic misconduct such as hiding assets.
Retirement at 65 as Substantial Change of Circumstances
In re Marriage of Cota, 113 Wn. App. 208 (2002)
Affirmed that modification of maintenance based on the payor’s retirement at age 65 constitutes a substantial change in circumstances under RCW 26.09.170, justifying a reduction or termination of the award.
Modifying Maintenance in Washington
Washington law allows modification of maintenance under RCW 26.09.170 upon a showing of a substantial and continuing change in circumstances.
1. Legal Standards for Modification
General Standard: A “substantial and continuing change in circumstances” since the last order is required. The change must be significant and not merely temporary.
Automatic Termination: Support terminates upon the recipient’s remarriage or death of either party, unless the parties agreed otherwise in writing.
Cohabitation: Does not automatically terminate maintenance per Rink (1977). Payor must petition and prove financial interdependence changed the recipient’s needs.
Retirement: Retirement at age 65+ constitutes a substantial change per Cota (2002). Early retirement (55–64) is evaluated on whether voluntary or health-related.
2. Common Grounds for Modification
Substantial Income Change: Significant involuntary reduction in payor’s income, or unexpected income increase for recipient.
Remarriage of Recipient: Automatic termination by operation of law.
Payor’s Retirement (65+): Substantial change under Cota. IRA/401k withdrawals may still be counted as income.
Disability: New or worsening medical condition affecting earning capacity of either party.
Recipient’s Improved Earning Capacity: Completion of rehabilitative plan, or significant new employment.
Wilcox (2024) Impact: Courts now have broader discretion; even if original order was based on pre-Wilcox need-focused analysis, modification petitions are evaluated under the current broader standard.
3. Step-by-Step Modification Process
Step 1 – File a Petition: Submit a Petition for Modification to the court that issued the original order.
Step 2 – Serve Notice: Legally notify the other party using certified mail or a process server.
Step 4 – Mediation: Many Washington courts require mediation before a contested hearing.
Step 5 – Court Hearing: If unresolved in mediation, present evidence to the judge. Burden of proof is on the party seeking modification.
Step 6 – Order on Modification: Effective from the date of filing; modifications are not retroactive.
4. Critical Practical Considerations
Never stop paying without a court order: Stopping payments can result in contempt, arrearages, and penalties.
No retroactive modification: Act promptly when circumstances change.
Timeline: Uncontested modifications: 2–4 months; contested: 6–18 months depending on county docket.
EHB 1014 (2026): Changes to child support calculations may indirectly affect payor’s ability to pay maintenance — a potential basis for modification.

Washington Spousal Maintenance FAQs (Updated 2026)
Has Washington changed how spousal maintenance is calculated?
Yes. The Washington Supreme Court’s 2024 decision in In re Marriage of Wilcox (No. 102401-1) significantly changed the legal landscape. The core law (RCW 26.09.090) remains the same, but the Court clarified that a spouse does NOT need to prove financial “need” to receive maintenance. Need is just one factor among many, and courts have broader discretion to award maintenance to achieve economic fairness. Additionally, effective January 1, 2026, the Child Support Economic Table was expanded by EHB 1014 with an income cap up to $50,000/month.
In re Marriage of Wilcox, No. 102401-1 (Wash. 2024); RCW 26.09.090
What did the 2024 Wilcox case say about “need” for maintenance?
In August 2024, the Washington Supreme Court ruled in In re Marriage of Wilcox that a requesting spouse does not have to demonstrate a specific “need” as a prerequisite to a maintenance award. The trial court must consider need along with the other statutory factors in RCW 26.09.090, but need is just one factor among equals and is not given automatic priority. The court’s “paramount concern is the parties’ economic conditions post dissolution.” Maintenance is a tool for achieving a fair economic outcome, not merely for providing bare necessities.
In re Marriage of Wilcox, No. 102401-1 (Wash. 2024)
What is the new 2026 Washington child support law, and how does it affect maintenance?
Effective January 1, 2026, Washington’s Child Support Economic Table was substantially updated by Engrossed House Bill 1014. Key changes include:
Expanded income range up to $50,000 combined monthly net income (increased from $12,000)
New minimum threshold starting at $2,200
Self-support reserve at 180% of federal poverty level (~$2,348/month)
Because child support is calculated before maintenance, higher child support reduces the payor’s ability to pay maintenance. Lower child support may increase the recipient’s demonstrated need (though Wilcox reduces need’s automatic importance).
How is maintenance calculated in Washington?
Washington uses statutory factors under RCW 26.09.090 rather than a strict formula. Courts often use 30% of payor’s gross minus 50% of recipient’s gross as an informal starting point. Under Wilcox (2024), need is not a prerequisite. Key factors: financial resources, time for education/retraining, standard of living during marriage, marriage duration, age and health of both parties, and ability to pay.
RCW 26.09.090; In re Marriage of Wilcox (2024)
How does marriage length affect maintenance in Washington?
Washington uses a 25-year threshold (not 20) for long-term marriages:
Under 5 years: Typically no long-term maintenance
5–25 years: Maintenance often lasts 20–33% of marriage length (or 50–75% in some cases)
25+ years: Indefinite maintenance possible
Disability, career sacrifice, or domestic violence may extend duration regardless of marriage length.
Can maintenance be modified or terminated in Washington?
Yes. Washington requires a substantial and continuing change in circumstances under RCW 26.09.170. Grounds include: payor’s retirement at a reasonable age (typically 65+), recipient’s remarriage (automatic termination), significant income changes, cohabitation with proven financial interdependence, or disability. Cohabitation alone does not automatically terminate maintenance per In re Marriage of Rink (1977).
RCW 26.09.170; In re Marriage of Cota (2002); In re Marriage of Rink (1977)
How does fault affect maintenance in Washington?
Washington is a no-fault divorce state. Per In re Marriage of Mattson (1999), marital misconduct generally does not affect maintenance awards. However, extreme cases of economic misconduct — such as hiding assets or intentional unemployment — may be considered by the court.
In re Marriage of Mattson, 95 Wn. App. 592 (1999)
How does retirement affect maintenance in Washington?
Per In re Marriage of Cota (2002), retirement at age 65+ constitutes a substantial change in circumstances justifying modification. Courts consider:
Early Retirement (55–64): Courts examine whether voluntary or health-related
Normal Retirement (65+): Typically qualifies as grounds for modification
Retirement Accounts: IRA/401k withdrawals may be considered as income
Social Security: Benefits may substitute for or reduce maintenance payments
In re Marriage of Cota, 113 Wn. App. 208 (2002); RCW 26.09.170
Are maintenance payments taxable in Washington?
For divorce agreements after December 31, 2018 (post-TCJA): Maintenance is NOT deductible for the payor and NOT taxable income for the recipient under federal law. Washington has no state income tax, so there is no additional state-level impact.
