Power of Attorney for a Child in Washington State

The health declaration lets you take the child to the doctor. The school caregiver form gets them enrolled. But neither gives you the kind of broad, documented authority that makes every interaction with every institution smoother for the next two years. That is what a Parental Power of Attorney does — and in Washington, the statute that governs it is RCW 11.130.145.

What a Parental POA Covers

Under RCW 11.130.145, a parent can delegate to another adult any of the parent's powers regarding the care, custody, or property of a minor child. In practice that means:

• Enrolling the child in school and making educational decisions
• Consenting to medical, dental, and mental-health treatment
• Authorising extracurricular activities, sports physicals, and field trips
• Managing the child's property and financial accounts
• Making childcare and daycare decisions

Two things a parental POA cannot do: consent to marriage, and consent to adoption. Those require judicial authority.

Who Has to Sign

The parent does. This is the key difference from the RCW 7.70.065 health declaration, which a relative caregiver can execute unilaterally. A parental POA is a delegation of authority from the parent — so the parent must be available and willing to sign.

Best practice is to have both parents sign if both have intact legal rights. A single-parent signature is legally effective against third parties when the other parent is deceased, absent, or cannot be located. But if the non-signing parent shows up later with intact rights, they can override the agent's authority at any time.

Execution Requirements

Washington's Uniform Power of Attorney Act (Chapter 11.125 RCW) sets the formalities:

• The document must be acknowledged before a notary public, or
• Signed before two disinterested adult witnesses who are not related to the parent or agent by blood, marriage, or domestic partnership

Notarisation is the stronger option. Under RCW 11.125.190 and 11.125.200, third parties (schools, clinics, banks) get statutory reliance protection when the document is notarised — meaning they can accept it in good faith without independent verification.

For parents who are incarcerated, Washington permits remote and electronic notarisation under the Revised Uniform Law on Notarial Acts (Chapter 42.45 RCW). Many correctional facilities have staff notary officers who can witness the execution.

The 24-Month Ceiling

A parental POA under RCW 11.130.145 maxes out at 24 months. After that, you either execute a new one (the parent signs again) or move to a more permanent arrangement. There is no automatic renewal.

This makes the POA a middle-ground instrument: four times the duration of a health declaration, with broader authority, but still temporary and still dependent on parental cooperation.

POA vs. Health Declaration vs. Guardianship

If the parent is available and cooperative, the POA is almost always the right move — it covers both school and medical authority in one document, lasts two years, and keeps everyone out of court. If the parent is missing or hostile, the health declaration handles medical consent and the school caregiver form handles enrolment, while you decide whether to petition for guardianship.
