What Is a Guardian ad Litem in Washington State?

A guardian ad litem in Washington State, often shortened to GAL, is a person the court appoints to investigate what arrangement serves the best interests of a child or incapacitated adult who cannot advocate for themselves in a legal case. The GAL is not that person’s lawyer. They work for the court, gathering facts and filing a written report with recommendations that judges weigh heavily when deciding custody, visitation, or guardianship.

In family law cases, GAL appointments are governed by RCW 26.12.175.¹ If your case involves a child and the court appoints a GAL, that person is about to become one of the most influential voices in the proceeding.

What a GAL Does in a Family Law Case

In divorce, parentage, and parenting plan modification cases, the court can appoint a GAL whenever it believes an independent investigation is needed to protect the child’s best interests.¹ The appointment order spells out which issues the GAL should examine. Common ones include allegations of domestic violence, substance abuse, mental health concerns, or a pattern of instability affecting the child.

The GAL investigates those issues and reports factual findings back to the judge, along with recommendations about the parenting plan. If the child has expressed a preference about which parent to live with, the GAL reports that preference and assesses whether the child is voicing it freely and understands what it means.¹ Judges rely on that assessment to tell the difference between a child’s genuine wishes and coaching by a parent.

A parallel statute, RCW 26.09.220, lets the court order a full investigation and report on parenting arrangements. That investigation can be done by the GAL, a court-appointed special advocate, juvenile court staff, or another professional social service organization.² Many courts simply fold both roles into one appointment.

One thing a GAL is not: your advocate, or your child’s attorney. They answer to the court. Treating conversations with the GAL as privileged or friendly is a mistake.

How a GAL Gets Appointed

Either party can ask the court to appoint a GAL, and the court can appoint one on its own. The statewide form is the Order Appointing Guardian Ad Litem (FL All Family 146), filed with a motion and supporting declaration.³

A motion asking for a GAL should describe the dispute and explain why an independent investigation serves the child’s best interests. Specific incidents in a sworn declaration carry more weight than general accusations. The motion is then served on the other party with a notice of hearing.

If the court grants the request, the order sets the scope of the investigation, the issues to examine, and a deadline for the report. That order also gives the GAL legal authority to access confidential records, interview people connected to the family, and visit homes.

What the Investigation Looks Like

Most investigations start with in-depth interviews of both parents. From there, the GAL typically observes the children with each parent in different settings and visits each home, sometimes with notice and sometimes without. Home visits let the GAL see living conditions, safety, and the day-to-day atmosphere firsthand.

The GAL also reaches outside the family. Under RCW 26.09.220, they can consult anyone who may have relevant information about the child or the possible parenting arrangements, and they can refer the child for professional evaluation with court approval.² That often means talking with teachers, pediatricians, therapists, and other professionals, and pulling criminal records, court files, medical records, and school reports.

Cooperating with the investigation is usually the right call even when the process feels invasive. Refusing to engage, missing appointments, or stonewalling on records tends to show up in the report. At the same time, the GAL is not conducting a criminal case against anyone. They are looking for what arrangement works best for the child.

The Report and Why It Matters

The investigation ends with a written report. By statute, the GAL must make it available to all parties no later than ten days before the hearing or trial.¹ The appointment order itself sets the filing deadline, and courts generally want the report well ahead of trial so the parties can respond.

The report lays out factual findings about the child’s situation, each parent’s strengths and concerns, and the GAL’s recommendations about the parenting plan. Both parties have the right to file written responses, and the court must consider those responses alongside the GAL’s findings.¹ When the investigation was ordered under RCW 26.09.220, either party can also call the GAL to testify and cross-examine them at the hearing.²

Judges are not bound by what the GAL recommends. In practice, they adopt the recommendations more often than not. That is why many cases are effectively decided when the report is filed. If you disagree with the conclusions, focus your written response on specific factual errors or evidence the GAL missed. Personal attacks on the GAL rarely land well with the judge who appointed them.

What It Costs and Who Pays

GAL services are not free, and in a contested case the bills add up fast. Professional GALs in Washington charge hourly rates that commonly reach up to $300 per hour, depending on experience and county. Many require an initial retainer deposit before starting work, sometimes running into several thousand dollars in complex cases.

The court enters an order allocating costs and may direct either or both parents to pay based on ability. Parties often propose a split in the motion for appointment, whether equal, proportional to income, or with one party advancing costs subject to reallocation. If both parents are indigent, the county covers the cost, subject to its appropriation for those services.¹

Paid GALs must give the parties an itemized monthly accounting of their time and billing.¹ Keep those statements. If a bill looks unreasonable, that documentation is what you take to the court. Not paying ordered fees can stall the investigation or lead to sanctions.

Challenging or Replacing a GAL

If you believe the assigned GAL is unqualified, has a conflict of interest, or charges an unreasonable hourly rate for your case, you can file a motion for substitution within three judicial days of the appointment.⁴ That window is short. Review the GAL’s background and rate as soon as you learn who was assigned.

After those three days, removal is harder. A court can still remove a GAL who engages in prohibited ex parte communications with the judge, meaning private, off-the-record conversations about the case. Washington’s adult guardianship statute treats such violations seriously enough to allow removal from the case, removal from the court’s registry, and forfeiture of fees on the case.⁵ Similar principles apply in family law under the statewide Guardian Ad Litem Rules.

Trying to remove a GAL mid-investigation because you dislike where it is heading rarely works. Courts expect a concrete reason tied to qualifications, conflict, or misconduct. For disagreements with the GAL’s conclusions, the better tools are the written response to the report and cross-examination at the hearing.

Filing a Grievance After the Case Ends

While your case is active, concerns about the GAL’s conduct go to the judge by motion. After the case closes, the process changes. You submit a written grievance to the county’s GAL Program Manager or Superior Court Administrator.⁶

Grievance procedures vary by county and usually live in the local superior court rules. If your county’s rules do not spell out a GAL grievance process, the Program Manager can explain how to file one. A grievance addresses professional conduct, not whether you agree with the recommendations. It will not change the outcome of your case. Only the trial judge or an appellate court can do that.

A Note on Adult Guardianship Cases

If you are dealing with a guardianship petition for an incapacitated adult rather than a child custody case, the terminology has changed. Washington replaced its old adult guardianship framework effective January 1, 2022 with the Uniform Guardianship, Conservatorship, and Other Protective Arrangements Act under RCW 11.130.⁷ Under the new law, the court appoints a “court visitor” to investigate the respondent’s situation and file a report at least 15 days before the hearing.⁵ The court can still appoint a GAL under RCW 11.130.075 when someone’s interests would not otherwise be adequately represented, but the investigative work in adult cases now runs through court visitors.
