Washington is one of approximately 20 states that permits courts to order divorced parents to contribute to their child's college expenses. Under RCW 26.19.090, Washington courts may order postsecondary educational support until a child turns 23 years old, provided certain requirements are met and a petition is filed before the child turns 18. Standard child support in Washington ends at age 18 (or high school graduation if later), but postsecondary support represents a separate, discretionary award that must be specifically requested through the Superior Court. With University of Washington in-state tuition running approximately $13,407 per year and total cost of attendance exceeding $35,000, understanding your rights and obligations regarding child support college expenses in Washington is essential for both paying and receiving parents.

How Washington Law Addresses Child Support and College Expenses
Washington law explicitly authorizes courts to order postsecondary educational support through RCW 26.19.090, making it one of the minority of states where parents can be legally compelled to pay for college after divorce. The standard child support economic table under RCW 26.19.020 does not include college expenses, meaning postsecondary support represents a separate legal framework entirely from basic child support obligations. As of January 1, 2026, House Bill 1014 updated Washington's child support guidelines to expand the economic table to cover combined monthly incomes up to $50,000 and raised the self-support reserve for low-income parents to 180% of the federal poverty level, but these changes do not alter the postsecondary support framework.
The child support college Washington framework operates on a fundamentally different basis than regular child support. While basic support follows mandatory guidelines and calculations, postsecondary educational support is entirely discretionary. Courts examine whether the child would have received college funding had the parents remained married, considering factors including parental education levels, family income history, and previously expressed expectations for the child's educational future. The economic table used for calculating standard child support is explicitly advisory, not mandatory, when courts consider postsecondary awards.
The Critical 18th Birthday Filing Deadline
The petition for postsecondary educational support must be filed before the child turns 18 years old, and missing this deadline permanently bars the claim. This strict cutoff represents one of the most important procedural requirements in Washington family law because no exceptions exist for late filings regardless of circumstances. If a support order already exists that terminates upon high school graduation, some courts have accepted petitions filed before graduation rather than before the 18th birthday, but relying on this interpretation carries significant risk.
Parents seeking college tuition divorce support must file in Superior Court rather than through the Division of Child Support (DCS). Administrative orders issued through DCS cannot include postsecondary educational support provisions. The petition must be filed in the county that issued the original child support order. Filing fees range from $314 in King County, Pierce County, and Snohomish County to $364 in Lincoln County, with fee waivers available for households earning at or below 125% of federal poverty guidelines ($19,406 for an individual or $39,750 for a family of four in 2026).
Factors Courts Consider When Ordering College Support
Washington courts evaluate multiple factors before ordering post-secondary support, with the central inquiry being whether the child would have received college funding had the family remained intact. Under RCW 26.19.090, courts must determine whether the child is in fact dependent and relying upon the parents for the reasonable necessities of life. The statute directs courts to consider the child's age, needs, aptitude, ability, and developmental limitations; the parents' level of education, standard of living, and current or future resources; the amount and type of support the child would have received if the parents had remained together; and the nature and cost of the postsecondary education being sought.
Courts also examine whether the child has demonstrated academic capability and commitment. A child who barely graduated high school with minimal effort faces a more difficult case than one with strong grades and clear vocational goals. The parents' own educational backgrounds carry weight, with courts more likely to order support when both parents hold college degrees and expressed expectations for their children to attend college. Financial resources receive scrutiny on both sides, including the paying parent's ability to contribute without severe hardship and the receiving parent's existing support obligations.
What Expenses Postsecondary Support Covers
Postsecondary educational support in Washington can encompass tuition, room and board, books, transportation to and from school, and other necessary education expenses. The court has discretion to determine which expenses fall within the scope of the award based on the specific circumstances of each case. University of Washington in-state tuition costs approximately $11,524 per year with $1,119 in fees, bringing the tuition and fees total to roughly $13,407, while total cost of attendance including room, board, books, and personal expenses reaches approximately $35,305 for in-state students.
Many attorneys advise capping postsecondary support obligations at the cost of attending a Washington public university to prevent a parent from becoming responsible for $60,000 or more per year at a private institution. This cap typically uses University of Washington tuition as the benchmark since it represents the state's flagship public university. Without such a cap in the order, a parent could theoretically be ordered to contribute to any accredited institution the child chooses, though courts retain discretion to limit awards based on reasonableness and the parents' financial circumstances.
Child's Obligations to Maintain Support
The child receiving postsecondary support must fulfill ongoing requirements to maintain eligibility under RCW 26.19.090. The child must enroll in an accredited academic or vocational institution, actively pursue a course of study commensurate with their vocational goals, and remain in good academic standing as defined by the institution. Additionally, the child must provide all academic records and grades to both parents, and each parent has full and equal access to postsecondary education records as provided in RCW 26.09.225.
Courts typically order that payments be made directly to the educational institution rather than to the child or the other parent. When direct institutional payment is not feasible, the court may order payments directly to the child if the child does not reside with either parent. This payment structure helps ensure funds are used for educational purposes rather than being diverted to other expenses. Failure to maintain academic standing or provide required records can result in suspension or termination of the support obligation.
Age 23 Limit and Exceptions
The court cannot order payment of postsecondary educational expenses beyond the child's 23rd birthday under standard circumstances. This hard cap means a child who begins college at 18 would receive support for approximately five years of higher education, sufficient for a bachelor's degree with some flexibility for changing majors or taking reduced course loads. The age 23 limit applies regardless of whether the child has completed their degree program.
Exceptional circumstances can extend support beyond age 23 when mental, physical, or emotional disabilities prevent the child from achieving self-sufficiency. These exceptions require specific findings by the court and substantial evidence of the disability's impact on the child's ability to complete education within the standard timeframe. Children with documented learning disabilities, chronic health conditions, or psychiatric conditions may qualify for extended support, but the burden falls on the requesting party to establish the necessity of the extension.
Defenses Against Postsecondary Support Orders
Parents can contest postsecondary support orders under several circumstances recognized by Washington courts. If the child has repudiated the relationship with the paying parent, meaning the child has voluntarily chosen to have no relationship with that parent, courts may decline to order support. This defense recognizes that parents should not be compelled to fund education for children who have completely rejected them, though the repudiation must be voluntary and not caused by the paying parent's own conduct.
Financial hardship presents another potential defense, particularly when the support obligation would force the paying parent into bankruptcy or severe financial distress. Courts balance the child's educational needs against the parent's ability to pay without sacrificing basic necessities. The court examines current income, existing debts, other support obligations, and future earning capacity. However, voluntary underemployment or attempts to hide income will not protect a parent from support obligations, as courts routinely impute income based on earning capacity.
How 2026 Child Support Changes Affect College Support
The January 1, 2026 updates to Washington's child support guidelines under House Bill 1014 primarily affect the economic table used for calculating standard child support rather than postsecondary educational support. The expanded table now covers combined monthly incomes up to $50,000 (up from the prior $12,000 limit) and increases the self-support reserve to 180% of the federal poverty level. These changes impact the baseline child support calculation that ends at age 18 or high school graduation.
Importantly, the 2026 changes removed educational expenses from the economic table, clarifying that K-12 tuition and similar expenses are treated as deviations from the standard calculation rather than included in the base amount. This separation further distinguishes standard child support from postsecondary support, which has always operated under the separate framework of RCW 26.19.090. Parents with existing support orders may seek modifications based on the new guidelines, but postsecondary support remains a distinct obligation requiring separate court orders.
Standard Child Support Termination vs. Postsecondary Support
Standard child support in Washington terminates automatically when the child reaches age 18 and has graduated from high school, or at the end of the month containing the child's 19th birthday if still enrolled in high school, whichever occurs first. Under RCW 26.09.170, no motion is required to terminate support when these conditions are met, though obtaining a formal termination order is advisable. If a child turns 18 in February but graduates in June, support continues through graduation. If graduation occurs at age 17, support continues until the 18th birthday.
Postsecondary support operates on an entirely different track. It does not automatically continue standard support into college but rather represents a separate court order that must be specifically requested before the child turns 18. A parent who fails to request postsecondary support before the deadline cannot later argue that college expenses should be covered. The two types of support can overlap briefly if a child turns 18 during high school and then begins college immediately after graduation, but they remain distinct legal obligations with different governing statutes and procedures.
Comparison: Washington vs. Other States
| State | College Support Available | Age Limit | Filing Deadline |
|---|---|---|---|
| Washington | Yes (discretionary) | 23 | Before child turns 18 |
| Oregon | No statutory authority | N/A | N/A |
| California | No (ends at 18) | 18/19 | N/A |
| New York | Yes (discretionary) | 21 | Before child turns 21 |
| Illinois | Yes (mandatory consideration) | Completion of degree | Before child turns 18 |
| Texas | No statutory authority | 18 | N/A |
Washington's approach to child support college expenses places it in the minority of states that authorize court-ordered postsecondary support. Unlike Oregon, California, and Texas where child support ends at majority without college provisions, Washington permits courts to extend financial obligations through the child's college years. Compared to Illinois, which requires courts to consider postsecondary support, Washington's discretionary framework gives judges more flexibility to deny requests based on circumstances.
Filing for Postsecondary Support: Step-by-Step Process
Filing for postsecondary support requires navigating Superior Court procedures before the child turns 18. The process begins with preparing a Petition for Modification of Child Support that specifically requests postsecondary educational support under RCW 26.19.090. The petition must be filed in the county that issued the original support order. Filing fees range from $314 to $364 depending on the county, as of March 2026.
After filing, the other parent must be properly served with the petition and given opportunity to respond. Washington's mandatory 90-day waiting period for divorce finalization under RCW 26.09.030 does not apply to modification petitions, so postsecondary support cases can proceed more quickly. However, contested cases requiring trial may take 12 to 18 months from filing to resolution. Parents should gather documentation supporting each factor the court will consider, including academic records, parental education histories, financial statements, and evidence of previously expressed college expectations.
Practical Strategies for Parents
For parents seeking postsecondary support, documentation is critical. Gather evidence showing the family's historical expectations for college attendance, including statements made before separation, contributions to college savings accounts, and both parents' educational backgrounds. Academic records demonstrating the child's capability and commitment strengthen the case. Financial documentation should establish both the paying parent's ability to contribute and the requesting parent's need for assistance.
For parents concerned about potential college support obligations, proactive negotiation during the divorce process offers the best opportunity to establish reasonable limits. Capping potential liability at the cost of University of Washington in-state tuition (approximately $35,305 total cost of attendance) protects against obligations for expensive private institutions. Requiring the child to apply for financial aid, scholarships, and student loans before parental contributions begin reduces overall exposure. Specifying which expenses are covered, requiring minimum academic performance, and establishing maximum timeframes all provide structure to what might otherwise be open-ended obligations.
