Power of Attorney vs Guardianship in Washington: Cost, Speed, and Control Compared
A sibling just told you your parent "needs a guardian." Before you agree, you should understand the difference — because a durable power of attorney and a court-ordered guardianship solve the same fundamental problem (someone needs legal authority to act for your parent), but they differ dramatically in cost, speed, privacy, and how much control your parent retains.
The Core Difference
A durable power of attorney (DPOA) is a private, voluntary document. Your parent — while still mentally competent — signs it to delegate authority to an agent of their choosing. No court involvement. No public record. No ongoing reporting requirements.
A guardianship (or conservatorship for finances) is a court-supervised proceeding under RCW 11.130. A judge determines that your parent lacks capacity, appoints a fiduciary, and imposes ongoing oversight. It's public, expensive, and strips your parent of certain legal rights.
Side-by-Side Comparison
| Factor | Durable Power of Attorney | Guardianship/Conservatorship |
|---|---|---|
| Cost | Minimal — forms + notary fee, or a few hundred dollars with attorney review | $3,000-$10,000+ in attorney fees, plus filing fees (examples include $240 in Snohomish County, $290 in King County, and $310 in Pierce County), medical evaluation, court visitor, and annual bond premiums |
| Timeline | Can be signed immediately, with effectiveness governed by the document's terms | A standard petition requires filing, investigation, evaluation, and a hearing; emergency appointments may be expedited but are limited to 60 days |
| Court involvement | None | Mandatory — petition, investigation, hearing, ongoing reporting |
| Privacy | Completely private | Public court record accessible to anyone |
| Parent's rights | Parent retains all legal rights; can revoke at any time while competent | Court restricts specific rights based on the guardianship order |
| Ongoing oversight | None — agent acts independently (with fiduciary duty) | Annual reports, financial accountings, court review of major decisions |
| Scope | As broad or narrow as the principal chooses | Determined by the court — can be full or limited |
| Requirement | Parent must have mental capacity to sign | Parent must lack capacity (proven by medical evaluation) |
When a POA Is Sufficient
For most families, a properly drafted DPOA is all you need. It works when:
- Your parent can still understand who they're appointing and what authority they're granting
- The family agrees on who should serve as agent
- The document includes durability language (required in Washington — RCW 11.125.040 doesn't presume it)
- "Hot powers" are explicitly granted under RCW 11.125.240 for gifting, trust creation, and beneficiary changes
- A healthcare POA is included alongside the financial POA
The agent acts without court supervision, which is both the advantage and the risk. There's no judge reviewing financial decisions. If siblings distrust the agent, their recourse is limited to filing a complaint or suing — there's no built-in accountability mechanism the way there is with conservatorship.

When Court Protection Is Necessary
Guardianship or conservatorship may be necessary when:
- Your parent has already lost capacity and never signed a POA — this is the most common reason. Once a person can't understand what they're signing, a valid POA can't be created.
- The existing POA is defective — missing durability language, lacking hot powers for Medicaid planning, or witnessed by disqualified individuals.
- The agent is suspected of abuse — if the person with POA authority is exploiting your parent, a guardianship petition can replace them with a court-supervised fiduciary.
- Third parties won't accept the POA — while RCW 11.125.200 mandates bank acceptance, some situations (particularly involving real property or government agencies) may be easier to resolve with court-issued Letters of Office.
- Family conflict is severe — when siblings can't agree on care decisions, a court-appointed guardian provides a neutral resolution mechanism.
The Middle Ground: Protective Arrangements
Washington offers a less-talked-about option under RCW 11.130: a protective arrangement instead of guardianship or conservatorship. The court authorizes a specific, limited action — signing a care facility contract, selling a house, approving a medical procedure — without establishing ongoing court supervision.
This is useful when a family needs authority for one transaction but doesn't need a permanent fiduciary appointment. It's faster and cheaper than full guardianship, and the parent's rights aren't broadly restricted.
The Real Cost of Waiting
The most expensive decision families make is no decision at all. While your parent has capacity, a DPOA costs very little and takes one afternoon. Once capacity is lost, you're looking at months of court proceedings, thousands in legal fees, and a public record of your parent's cognitive decline and financial situation.
The math is simple: proactive planning with a POA now, or reactive court protection later at a far higher cost.
The Washington Power of Attorney & Guardianship Kit covers both paths — the DPOA setup you should do now and the guardianship roadmap in case the window has already closed.
