Washington Guardianship for Minor Children — How to File
Nominating a guardian for your children — what happens if you don't, and how to plan ahead.
Guardianship for minor children §11.130.215
Your will is the primary way to nominate a guardian for your minor children. Without a nomination, the court decides — and the process can be contentious if family members disagree.
How guardian nomination works
Guardianship for incapacitated adults §11.130.265; §11.130.360
When an adult can no longer manage their own affairs and has no Power of attorney or other advance planning in place, a family member or interested party can petition the court for guardian and conservator §11.130.265; §11.130.360.
Why guardianship is a last resort
- It requires a court proceeding with legal fees and ongoing reporting
- The incapacitated person loses legal rights — the court, not the family, decides who serves
- The guardian must file periodic reports and accountings with the court
- It is public — anyone can access guardianship records
A Power of attorney and healthcare agent, created while you have capacity, avoid the need for guardianship entirely. These documents let you choose your own agent privately and without court involvement.
Guardian vs. conservator
| Guardian of the person | Conservator / guardian of the estate | |
|---|---|---|
| Scope | Personal decisions — housing, medical care, daily needs §11.130.265; §11.130.360 | Financial decisions — assets, bills, investments |
| Who needs it | Someone who cannot make personal decisions | Someone who cannot manage finances |
| Court oversight | Periodic reports on the person's well-being | Financial accountings filed with the court |
| Can be same person | Yes — the court may appoint one person for both roles | Yes, but splitting responsibilities is sometimes better |
Washington adopted the Uniform Guardianship, Conservatorship, and Other Protective Arrangements Act (RCW § 11.130.005 et seq.). When appointing a guardian for a minor, the court must appoint a person nominated by a parent in a probated will or other record unless the appointment is contrary to the minor's best interest (RCW § 11.130.215). An order appointing a guardian for an adult must find by clear and convincing evidence that the adult's needs cannot be met by a less restrictive alternative, including supported decision making (RCW § 11.130.310).
