How Much Does a Guardian ad Litem Cost in Washington State? The Real Numbers Nobody Publishes.
Cost Analysis · By Gale McArthur · 2026-05-06 · 10 min read
A Guardian ad Litem in Washington costs $3,000–$15,000+ depending on county. In King County, expect $300–$350/hour with retainers of $5,000–$10,000. Here are the numbers nobody publishes.
If you're searching this question, you're probably already stressed. You're in a custody case, someone mentioned a GAL, and now you're trying to figure out what this is going to cost you before you agree to anything. I've been where you are. Here's what I wish someone had told me.
The cost of a GAL is rarely published — but it shapes every custody outcome.
The Short Answer
In Washington State, a Guardian ad Litem will cost you somewhere between $3,000 and $15,000+ depending on your county, the complexity of your case, and whether the GAL is court-appointed or privately retained. In King County specifically, you should expect to pay $300–$350 per hour with retainers starting at $5,000–$10,000.
Those numbers are not published anywhere by King County. I know them because I called all 25 GALs on the King County registry. Every single one.
What You'll Actually Pay, by County
The cost of a GAL varies dramatically depending on where your case is filed, and almost none of this information is easy to find.
- King County (Seattle): $300–$350/hour for private-pay GALs. Retainers of $5,000–$10,000. No published rate schedule. No fee cap. The county does not publish GAL rates, contact information, or availability — you have to call around yourself. I paid $10,000 for a parenting evaluator who was also on the GAL registry.
- Snohomish County (Everett): $150–$250/hour. Retainers of $1,500–$3,500. This county actually publishes its entire private-pay GAL registry online with names, hourly rates, retainer amounts, credentials, and contact information. You can see exactly what you're paying for before you agree.
- Pierce County (Tacoma): Approximately $100/hour for county-rate GALs. Published registry with contact information.
- Clark County (Vancouver): Retainers typically range from $8,000–$10,000. Timeline of 6–12 months for a full evaluation.
Why King County Costs So Much More
There are 25 GALs on King County's Title 26 registry serving a population of 2.3 million people — including 441,000 children. When I called all 25, not a single one had availability for a new case.
Zero availability plus no fee cap equals $350/hour. That's basic supply and demand — except the supply is controlled by the court, and the court has done nothing to expand it.
Neighboring counties require 6–12 hours of continuing education per year and cap fees at roughly $100/hour for county-rate appointments. King County has no CE requirement and no fee cap. The county confirmed in writing that continuing education credits are not required to remain on the GAL registry.
So you're paying 3x more per hour than families in Pierce County — and there's no mechanism verifying that the person you're paying has current training in domestic violence, coercive control, child development, or any of the laws that have changed since they were first credentialed.
What a GAL Actually Does (and Doesn't Do)
A Title 26 GAL in Washington is appointed to represent the best interests of a child in a family law case. They investigate, interview parents and children, review records, and make recommendations to the judge about custody and parenting plans.
Here's what most parents don't realize: the judge almost always follows the GAL's recommendations. In my case, the judge gave the evaluator's testimony "100% weight." That means the person you're paying $350/hour effectively decides your custody outcome.
That makes their qualifications critically important. And here's the problem.
What You're Not Told About Their Qualifications
Under Washington law, GALs are required to complete an initial 32-hour training and comply with ongoing training requirements under RCW 26.12.177(1) and RCW 2.56.030(15). The GAL rules (GALR 2(d)) require them to "satisfy all training requirements and continuing education requirements" and "maintain qualifications."
Since 2021, Washington has passed three major pieces of legislation that fundamentally changed how domestic violence is assessed in family law:
- HB 1320 (2021) reformed and unified all civil protection order types.
- Coercive control became law in 2022 under RCW 7.105.010 — domestic violence no longer requires physical injury or police reports.
- HB 1620 (2025) now requires that any professional expressing opinions on abuse demonstrate "expertise and substantial direct experience working with victims of domestic violence or child abuse" that is "not primarily forensic in nature."
The evaluator in my case was trained in 2002. He had no documented continuing education since then. He told the court there was no domestic violence because there were no police reports — a framework Washington law explicitly rejected three years ago. The court gave his opinion 100% weight and gave the nationally recognized DV expert who trains GALs effectively zero weight.
When I asked about continuing education, the answer came in a March 24, 2026 email: "Continuing education credits are not required to remain on the GAL registry."
You are paying $350/hour for unverified expertise.
Questions to Ask Before You Agree to a GAL
Before you consent to a GAL appointment or agree to a parenting evaluator, ask these questions. You have a right to know what you're paying for.
About cost: - What is your hourly rate? - What is your retainer? - What is your estimated total cost for a case like mine? - Do you bill separately for trial preparation and testimony? - Will you provide itemized invoices?
About qualifications: - When did you complete your initial GAL training? - What continuing education have you completed in the last 3 years? - Do you have specific training in domestic violence and coercive control? - Are you familiar with HB 1620 and the 2022 coercive control statute (RCW 7.105.010)? - Do you hold any clinical credentials (psychology license, counseling license, social work license) or are you an attorney-only GAL? - How many evaluations have you completed?
About process: - How long will the evaluation take? - Will you interview the children? - Will you review police records, medical records, and school records? - Will you obtain CPS records under RCW 13.50.100? - How do you assess for domestic violence when there are no police reports?
If the answer to that last question involves the phrase "no police reports, so no DV" — that is a red flag. Washington law no longer works that way.
What to Do If You Can't Afford a GAL
This is the hardest part. The system is set up so that the people who need GALs the most — parents in domestic violence situations, pro se litigants without attorneys — are the ones least able to afford $350/hour.
- Family Court Services (FCS): King County offers parenting plan evaluations through Family Court Services at reduced or no cost, but the waitlist can be long and the scope may be more limited than a private evaluation.
- CASA (Court Appointed Special Advocates): CASA volunteers are appointed in some cases and serve at no cost. They are not the same as a GAL but can provide the court with information about the child's situation.
- Ask the court to apportion fees: Under Washington law, the court can split GAL fees based on each party's income, or assign the full cost to the party who requested the GAL if the court doubts it would be useful.
- Object to the appointment: You are not required to agree to a GAL. If you believe the cost is prohibitive or the proposed evaluator is not qualified, you can object and state your reasons on the record.
The Bigger Problem
The cost of a GAL is not just a financial issue. It's an access-to-justice issue.
When a county of 2.3 million people has only 25 GALs on its registry, charges $300–$350/hour with no cap, publishes no contact information, requires no continuing education, and cannot produce a record showing any GAL has current DV training — that is a system designed for people with money and attorneys.
If you're a pro se parent, a DV survivor, or someone who just can't afford $10,000 for an evaluation, the system is not built for you.
You're not broken. The system is.
