Guardianship Cost Estimate for King County

For an uncontested guardianship petition in King County, budget $3,500–$9,000 for attorney fees. This range reflects both the complexity of a standard petition under Washington law and local attorney hourly rates in the Seattle area, which typically run $300–$500/hour.

In King County, this notice must be served in compliance with the court's local rules as well as the statewide statutory requirements.

Guardian Ad Litem in King County, Washington

Visitor or attorney appointed (RCW § 11.130.205). In King County, the King County Superior Court routinely appoints an independent advocate — variously called a guardian ad litem, court visitor, court evaluator, or attorney ad litem depending on the state's statutory terminology — to independently investigate whether guardianship is necessary and appropriate. This person meets with the proposed ward, interviews family members, reviews medical records, and submits a written report and recommendation to the court.

The GAL or court visitor's fees are considered a cost of the guardianship proceeding and are typically paid from the ward's estate. In most Washington jurisdictions, including King County, the court sets the GAL's fee at a reasonable hourly rate. For simple, uncontested cases in King County, the GAL's total fees often range from $500 to $1,500. In contested proceedings, the investigation may be more extensive and the fees correspondingly higher.

The GAL's recommendation carries significant weight with the King County Superior Court, but it is not binding. In some cases, the GAL's investigation reveals that a less restrictive alternative — a durable power of attorney, representative payee designation, or supported decision-making agreement — would adequately protect the proposed ward without full court-supervised guardianship. Raising these alternatives early in the process can reduce costs and preserve the ward's autonomy.
