Guardians ad litem and child representation in Washington: who they are, what they owe your child, and who pays

If custody is contested in Washington, the court can appoint someone to look into your family and report to the judge. This page is what Washington’s own statutes and court rules say about who that person is, what duty they owe, and — the part almost nobody asks in time — who pays for them.

What the role is called here

guardian ad litemcourt-appointed special advocate (CASA)

Names matter more than they look. A guardian ad litem generally argues for what they judge is best for your child and is not your child’s lawyer. An attorney for the child argues for what your child actually wants. Those are opposite duties. The four roles, explained in full.

How an appointment happens

RCW 26.12.175
The court may appoint a guardian ad litem to represent the interests of a minor or dependent child when the court believes the appointment of a guardian ad litem is necessary to protect the best interests of the child in any proceeding under this chapter.

What duty they owe your child

best interests

In the statute’s own words
The guardian ad litem’s role is to investigate and report factual information regarding the issues ordered to be reported or investigated to the court. The guardian ad litem shall always represent the best interests of the child.

Who can be appointed

RCW 26.12.175 contemplates both compensated (non-attorney) guardians ad litem and volunteer/CASA guardians ad litem (‘Guardians ad litem who are not volunteers shall provide the parties with an itemized accounting of their time and billing for services each month’); it does not require the appointee to be a licensed attorney, and the role is described as investigative/reporting rather than legal representation.

Who pays

RCW 26.12.175(1)(d)
The court shall enter an order for costs, fees, and disbursements to cover the costs of the guardian ad litem. The court may order either or both parents to pay for the costs of the guardian ad litem, according to their ability to pay.

If you cannot pay

RCW 26.12.175(1)(d): ‘If both parents are indigent, the county shall bear the cost of the guardian, subject to appropriation for guardians’ ad litem services by the county legislative authority.’

There is no published price

We looked for an official Washington fee schedule for privately appointed guardians ad litem and custody evaluators, and did not find one. That is true of almost every state — only Minnesota and Massachusetts publish figures, and both are subsidised program rates rather than market ones.

The numbers circulating online come from law-firm marketing pages. We will not repeat those as though they were sourced. Call your county family court clerk and ask what appointees there actually charge. It is local, current, and free.

Custody evaluations

Washington governs court-ordered custody evaluations and investigations separately from the appointment of a guardian ad litem. An evaluator is a witness, not an advocate — and their recommendation is a recommendation, not a ruling a judge is bound by.

Before an evaluation begins, it is worth asking which psychological instruments will be used. The peer-reviewed literature is openly critical of several still in circulation — one has interrater reliability reported as ranging from 50% to 100%. The evidence, in full.

The thing worth knowing about Washington

Washington explicitly builds a county-funded backstop into its GAL fee statute: if the court finds both parents indigent, RCW 26.12.175(1)(d) shifts the entire cost of the guardian ad litem to the county (subject to the county legislative authority’s appropriation for GAL services), rather than leaving indigent parents to go without a GAL or the appointee to serve unpaid. The statute also maintains detailed statewide background-check and registry requirements (RCW 26.12.175(3)) for every GAL, whether volunteer/CASA or paid.

What this means. This is when the sources on this page were last read against their originals — statutes, court rules, official schedules — taken from the date this page was built from its sources. It is not the date the page was last edited. Adding a link or fixing a typo does not move it; re-reading the statute does. Law changes without notice, so treat anything time-sensitive as needing a fresh check. Where we get something wrong we publish it at thecusp.app/corrections with the date, what changed, and how long the error was live.
