# When Does Child Support End in Washington State? - Hodgson Law Office - / - Blog - /blog - When Does Child Support End in Washington State? ## Table of Contents If your support order says payments run until your child turns 18 or finishes high school, whichever comes later, that sentence is your answer. If your order does not say, Washington's default is the 18th birthday. Which of those you are looking at depends on three things: which body issued your order, how that order words its end point, and where your child is in school right now. The first two are answerable from the document you already have. > **The short version.** Support runs to whatever end point your order names. Where an order is silent, it ends at 18. Orders from the state's child support agency stop at 18 or graduation, and never later than the month your child turns 19. Support can end sooner, and it can run longer for a dependent adult child or through a separate award for college or trade school. ## Washington's Child Support Termination Rules Washington's termination rule for court-ordered support sits in one sentence of statute, and the important part is the opening clause. Under [RCW 26.09.170(3)](https://app.leg.wa.gov/RCW/default.aspx?cite=26.09.170): > "Unless otherwise agreed in writing or expressly provided in the decree, provisions for the support of a child are terminated by emancipation of the child or by the death of the person required to pay support for the child". Two words there do the work. A **decree** is the court order that ended your marriage or established support, the document you were handed at the end of your case. **Emancipation** is when a child stops being a legal dependent, and [RCW 26.28.010](https://app.leg.wa.gov/RCW/default.aspx?cite=26.28.010) sets Washington's age of majority at 18. So the statutory default for a court order is the 18th birthday. What makes that default easy to miss is the clause that comes before it. Where a decree expressly provides for something else, the decree controls. So the rule you have probably heard, that support runs to "18 or graduation, whichever is later," comes from the wording of a [child support order](https://hodgsonlawoffices.com/family-law/child-support) rather than from a statute that applies on its own. Read your order to see which of the two applies to you. **Which marriage matters.** Subsection (4) ends support provisions if the two parents marry or remarry each other, unless the order expressly says otherwise, and the rest of the order stays in force. The child support provisions do not address marriage to anyone else. Remarriage does end spousal maintenance under subsection (2), which is a different obligation. ## What the End Date Means for Your Household For the parent receiving support, the end date is not a legal milestone. It is the month a line disappears from a budget that was built around it, and it can arrive while your child still lives at home, still eats, and still needs a phone and a car. **Knowing the date early is what gives you options.** It tells you how long you have to plan around the gap, and whether anything can extend it. If your child has a disability or is heading to college or a trade program, you must make a request before your current order ends. After it ends, that door is closed. **For the parent paying support, the same date matters for the opposite reason.** Stopping before it arrives creates arrears. Continuing past it means paying money you no longer owe, and getting it back is harder than not paying it. ## Court Order or Administrative Order Washington support orders come from two places, and the difference affects both the end date and whether support can reach past high school. An **administrative order** is issued by the [Division of Child Support](https://www.dshs.wa.gov/esa/division-child-support), the state agency inside the Department of Social and Health Services that establishes and collects support. A **court order** is entered by a Washington Superior Court in a divorce, a paternity case, or a support case. **If yours is an administrative order.** The Division of Child Support’s [rule on the duration of an administrative support order](https://www.law.cornell.edu/regulations/washington/WAC-388-14A-3810) sets it to run until the child turns 18. It continues past 18 only if the child is under 19 and attending a secondary school program full time. Support does not extend beyond the child’s 19th birthday. The same rule lists the child’s marriage, emancipation, enlistment in the armed forces, or death, and the death of the paying parent, as events that end the obligation, along with the parents marrying or remarrying each other. A court order entered later replaces the agency’s order. **If yours is a court order.** It ends on the terms written into it, measured against RCW 26.09.170. The difference matters most if college is ahead. [RCW 26.19.090](https://app.leg.wa.gov/RCW/default.aspx?cite=26.19.090) assigns **postsecondary educational support**, meaning support for education after high school, to a court at every step: the court determines dependency, the court weighs the factors, and the court is the body directed not to order expenses past a certain age. If your only order is an administrative one, plan on a Superior Court case to have that considered, and plan on starting it while your existing order is still running. Where your order came from also decides where you go to change it. An order from a divorce, a [paternity case](https://hodgsonlawoffices.com/family-law/paternity), and an agency are each amended in a different place. ## Read the Termination Language in Your Own Order Because RCW 26.09.170(3) hands control to the decree wherever the decree speaks, the paragraph in your order that names the end point is the most useful thing you can read today. You are looking for the provision that ties the end of the obligation to an age, an event, or both. Three things you might find: - **A named event or date.** The order states when support ends. That language controls over the statutory default. - **Silence.** The order says nothing about the end point. The default in RCW 26.09.170(3) applies, which means 18. - **A reservation.** The order says postsecondary educational support is "reserved." That preserved the right to raise the issue later. It is not an award, and on its own it does not create a second payment running alongside regular support. Someone still has to ask the court, and asking has to happen while the order is still in force. If a [parenting plan](https://hodgsonlawoffices.com/family-law/parenting-plan) was entered alongside your support order, read both. They are entered together and can cross-reference each other. ## Does Child Support Stop Automatically The obligation and the paycheck deduction are two different things, and only one ends automatically. **The obligation ends on its own.** RCW 26.09.170(3) terminates the support provisions when the terminating event happens, without anyone filing a petition to make that happen. Reaching the end point written into your order does not require a court appearance. **Withholding does not.** A wage deduction is administered separately from the obligation itself, and it continues until whoever collects on your order has the end date on file. The practical move is to raise it in writing with the body that is actually collecting, and to have the date documented when you do. **Documentation is easier to produce now than later.** A diploma, a school verification letter, a marriage certificate, or a court emancipation order is the kind of paper that establishes a date, and the date is what stops collection. For the parent receiving support, a documented end date is the record of which payment was the last one owed. For the parent paying, it is the difference between ending an obligation cleanly and finding out later that [child support enforcement](https://hodgsonlawoffices.com/blog/enforcing-washington-child-support-orders) has been running the whole time. ## If Your Order Covers More Than One Child This is where the most expensive mistake on this page happens, and the arithmetic is what causes it. **One order, one figure.** An order covering two or three children sets a single amount. It does not break that amount into a per-child share, so when your oldest reaches the end point, there is no share to subtract, and cutting your payment yourself does not change what the order requires. **What the statute does about it.** RCW 26.09.170(1)(a) lets a **modification**, meaning a court or agency change to an existing order, reach only the installments that come due after the request is filed. Everything that came due before then stays owed at the original amount. Pay two-thirds of a three-child order after one child ages out, and the missing third accrues as arrears month after month until you file and get a modification. If your order covers more than one child and one of them is close to the end point, filing is the step that lowers the payment. Nothing else does. #cta_here ## When Child Support Ends Before Age 18 Some events end a support obligation before the child reaches the normal endpoint because each ends the legal dependency the order was built on. ### Emancipation of the Child RCW 26.09.170(3) names emancipation as a terminating event. Beyond simply reaching 18, a minor can petition a Washington court for a declaration of emancipation under [chapter 13.64 RCW](https://app.leg.wa.gov/RCW/default.aspx?cite=13.64), and a granted petition ends the obligation. ### Marriage of the Child Marriage can make a minor a full adult by statute. [RCW 26.28.020](https://app.leg.wa.gov/RCW/default.aspx?cite=26.28.020) provides that a minor married to a person of full age is deemed to be of full age, and the Division of Child Support lists a child's marriage among the events that end an administrative support order. ### Military Enlistment The Division of Child Support also lists enlistment in the United States armed forces as an event that ends an administrative order. ### Death of the Child or the Paying Parent RCW 26.09.170(3) terminates support provisions on the death of the person required to pay. A balance that accrued before that date remains a debt and does not disappear when the obligation ends. For each of the last three, a court order is governed by the end point written into it rather than by the agency's list. ## When Child Support Continues Past Age 18 Two situations extend support past the normal end point, and neither of them happens by itself. Find the row that matches your child: Your Child General Result What to Check **Turns 18 During Senior Year** Support runs to graduation where the order says "whichever is later" The end-point wording in your order **Graduates at 17** Support runs to the 18th birthday The confirmed graduation date, in writing **Turns 19 While Still in High School** Administrative orders end that month; court orders follow their own terms Which body issued your order **Will Not Graduate on Time** Your order's stated end point still governs Whether the school still counts your child as full-time **Starts College or Trade School** Support does not extend on its own Whether postsecondary support was reserved or awarded **Remains Dependent on You as an Adult** Support can continue, with dependency as the question How soon you can raise it, before the order lapses ### Continued Support for a Dependent Adult Child Washington's support rules are not written only for minors. [RCW 26.19.035(1)(f)](https://app.leg.wa.gov/RCW/default.aspx?cite=26.19.035) applies the child support schedule to adult children who are dependent on their parents and for whom support is ordered under [RCW 26.09.100](https://app.leg.wa.gov/RCW/default.aspx?cite=26.09.100), and directs that the same standards and the same reasons for deviation apply as in any other case. What the statute does not do is set an age limit for that situation or spell out which circumstances qualify. Dependency is the question, and it's answered by the facts of the individual child rather than by a rule you can look up in advance. That's why you should raise a known long-term condition while your order is still in force, not in the weeks before it lapses. You can [estimate support payments](https://hodgsonlawoffices.com/child-support-calculator) under the current schedule while you plan. ### Postsecondary Educational Support Regular child support does not extend into college on its own. Support for education after high school is a separate award, and a parent or the child has to ask a court for it under RCW 26.19.090. The statute is specific about what happens once support is awarded, and five points in it are worth knowing before you file. - **There is no table that produces the number.** RCW 26.19.090(1) makes the child support schedule advisory, not mandatory, for postsecondary support. - **Dependency comes first.** The court determines whether the child is in fact dependent and relying on the parents for the reasonable necessities of life, then weighs the child's age, needs, prospects, aptitudes and disabilities, the nature of the education sought, the parents' education, standard of living and resources, and what the child would have received had the parents stayed together. - **Accreditation is the test, not the format.** The child must enroll in an accredited academic or vocational school, actively pursue a course of study that matches their goals, and remain in good academic standing as the school defines it. Whether classes run on campus or online is not the criterion. An award is automatically suspended for any period the child fails those conditions. - **Records go to both parents.** Both parents must have access to academic records and grades as a condition of receiving support. - **Age 23 is the ceiling.** A court cannot order postsecondary expenses beyond the child's 23rd birthday, except for exceptional circumstances such as mental, physical, or emotional disabilities. Payment goes to the school where that is workable, and otherwise to the child or the parent depending on where the child lives. **Timing deserves more attention than the paperwork.** Two provisions of RCW 26.09.170 sit together here, and reading them in sequence explains why the calendar matters. Subsection (1) permits modification of the provisions of a decree respecting maintenance or support. Subsection (3) terminates a decree's child support provisions once the terminating event arrives. A request to extend support is a request to modify provisions, which means those provisions need to still be in place when the request is made. Two things follow from that: - **If your order reserved postsecondary support**, the reservation is what keeps the question open. - **If it did not**, the question has to be raised while the order is still running, which makes the end point written in your order the date to work backward from. RCW 26.09.170(8)(b) separately allows a modification a year or more after entry, without a showing of substantially changed circumstances, on a finding that support needs to extend past the 18th birthday to complete high school. If a deadline is approaching, this is the time to have an experienced attorney review the order rather than reading it alone. ## How to Modify or Terminate a Support Order Where you file depends on which body issued your order, so start there rather than with a form. A Superior Court order is modified through the court that entered it, and an administrative order goes through the agency's own [child support modification](https://www.dshs.wa.gov/esa/division-child-support/child-support-modification) process. Filing in the wrong forum costs time you may not have if an end point is close. RCW 26.09.170 offers more than one route: - **Substantially changed circumstances.** Under subsection (5)(a), a party may petition at any time on that showing. Subsection (5)(b) adds that voluntary unemployment or underemployment, by itself, is not a substantial change. - **One year after entry, without that showing.** Subsection (8) allows modification where the order works a severe economic hardship, or on a finding that support needs to extend past the 18th birthday to complete high school. - **Adjustment after 24 months.** Subsection (9) allows an adjustment without showing changed circumstances, based on income changes or changes to the economic table, and can be initiated by motion with support worksheets. Our dedicated [family law attorneys](https://hodgsonlawoffices.com/family-law) can tell you which route fits your situation and what each one requires. ## Past-Due Support Does Not Disappear Reaching the end of a support obligation does not erase a balance that built up before it, and the statute is the reason. RCW 26.09.170(1)(a) allows modification only as to installments accruing after a petition is filed. Everything that accrued earlier under the existing order remains owed, which is why arrears survive the 18th birthday, graduation, and the formal end of the ongoing obligation. Collection does not stop because the ongoing obligation did, and Washington's enforcement statutes in [chapter 26.18 RCW](https://app.leg.wa.gov/RCW/default.aspx?cite=26.18) stay available against a past-due balance. Our piece on [unpaid child support](https://hodgsonlawoffices.com/blog/unpaid-child-support-may-attract-new-consequences) covers the current tools and penalties. **Health care is a separate line, not part of the transfer payment.** [RCW 26.19.080(2)](https://app.leg.wa.gov/RCW/default.aspx?cite=26.19.080) keeps health care costs out of the economic table and has the parents share them in the same proportion as the basic obligation. Read what your order says about health insurance and uninsured medical costs on its own terms rather than assuming it follows the same end date. **If the amount was wrong from the start, that is a different question.** Our discussion of a [formula deviation](https://hodgsonlawoffices.com/blog/can-there-be-a-deviation-from-the-child-support-formula-in-wa) covers the grounds for that argument, which is separate from anything about when support ends. ## How Washington Calculates Child Support Everything above is about when support ends. If what you need is how much, that sits in a different part of the statute. RCW 26.19.080(1) takes the basic obligation from the economic table and allocates it between the parents by each parent's share of their combined monthly net income. You can work through the numbers with the [Washington State Child Support Schedule](https://www.courts.wa.gov/forms/?fa=forms.contribute&formID=73). ## Know Where You Stand Before the Next Payment The general rule gives you a starting point, not an answer. Your date comes from three things read together: which body issued your order, what the end-point paragraph in that order says, and where your child is in school right now. Read those three, and you will know whether you are looking at a straightforward end point or a deadline. If it is a deadline, you need to find out before it arrives, because RCW 26.09.170 lets a court modify existing support provisions and terminates them once the end point is reached.
