Hawaii Power of Attorney Requirements
Hawaii’s Uniform Power of Attorney Act (HRS Chapter 551E) sets how a Power of Attorney is signed, when it continues through incapacity, and what an agent must do. Here are the essentials in plain English, each linked to the official Hawaii Revised Statutes.
Based on Hawaii Uniform Power of Attorney Act, HRS Chapter 551E. Reviewed October 2026. Education, not legal advice — Hawaii’s requirements are set by state law and can change, so confirm them with an official Hawaii source or a licensed attorney.
Preparing to serve—or already serving—in Hawaii?
The National Handbook explains the responsibilities. The National Workbook helps you organize the work. Use the Hawaii information below to explore requirements, official sources, and available resources.
Requirements depend on your documents and applicable law. Confirm current information with official sources or a qualified professional in your state.
Where is Hawaii’s Power of Attorney law?
Hawaii’s financial Power of Attorney law is the Uniform Power of Attorney Act, HRS Chapter 551E. It includes an optional statutory form (HRS § 551E-51).
Does a Hawaii Power of Attorney have to be notarized?
Under HRS § 551E-3, the principal signs the Power of Attorney (or another person signs in the principal’s conscious presence at the principal’s direction). A signature acknowledged before a notary public is presumed to be genuine, and an acknowledged Power of Attorney gets the acceptance protections in §§ 551E-15 and 551E-16. The statutory form includes a notary block.
Is a Hawaii Power of Attorney durable?
By default, yes. Under HRS § 551E-3, a Power of Attorney shall be durable unless it expressly provides that it is terminated by the incapacity of the principal.
When does a Hawaii Power of Attorney take effect?
Under HRS § 551E-5, a Power of Attorney is effective when signed unless it says it becomes effective at a future date or on a future event, such as incapacity. The statute explains how incapacity is determined if the document does not name someone to decide.
What does a Hawaii agent have to do?
Under HRS § 551E-10, an agent must act according to the principal’s reasonable expectations (or best interest), in good faith, and only within the authority granted. Unless the document says otherwise, the agent must also act loyally, avoid conflicts of interest and keep a record of all receipts, disbursements and transactions. The principal, a guardian, a conservator and certain others can request disclosure, generally within 30 days.
What happens to a spouse-agent’s authority in a divorce?
Under HRS § 551E-6, unless the Power of Attorney says otherwise, a spouse-agent’s authority ends when an action is filed for dissolution, annulment or legal separation.
How is a Hawaii Advance Health-Care Directive signed?
Healthcare decisions are covered separately by an Advance Health-Care Directive under HRS Chapter 327E. Under § 327E-3, a power of attorney for health care is signed and dated, then signed by two witnesses or acknowledged before a notary public. A witness may not be a health-care provider, an employee of a health-care provider or facility, or the agent, and at least one witness must be unrelated to the principal and not entitled to any part of the estate. The Hawaii Executive Office on Aging links to the form.

The universal rules of the role
The exact forms, witnessing, and notarization rules change from state to state — those are in Hawaii’s essentials above.But the heart of the role is the same everywhere in the U.S. Here’s what always applies.
Your duties as an agent
Every decision is for the principal, never for you. This is the core legal duty of an agent, everywhere.
Never mix the principal’s funds with your own. Use their accounts for their expenses, and don’t borrow or lend to yourself.
Track every transaction, receipt, and major decision. Good records protect the principal — and protect you if anyone ever asks.
You can only do what the Power of Attorney actually authorizes. If it isn’t granted in the document, you don’t have the authority.
Follow what they’d want, preserve their existing estate plan where you can, and avoid anything that benefits you at their expense.
What a Power of Attorney can’t do
A Power of Attorney works only while the principal is alive. The moment they pass, it ends and the will and executor (or trustee) take over.
An agent cannot make or rewrite the principal’s will, and generally can’t change beneficiary designations unless the document specifically allows it.
Powers not written into the document — like making gifts or changing accounts — usually aren’t allowed. When in doubt, it’s probably not authorized.
When you sign correctly as the agent (not personally), you’re acting for them — you don’t take on their debts by serving.
How to sign as an agent
Always sign in your representative capacity — never just your own name on the principal’s business. A safe format anywhere is “Jane Doe, as agent for John Doe” (some institutions prefer “John Doe by Jane Doe, agent”). Signing your name alone can make you personally liable; signing as the agent makes clear you’re acting for them.
When the authority ends
- The principal revokes it — they can, at any time, as long as they’re competent.
- The principal dies — authority passes to the will or trust.
- A court appoints a guardian or conservator, or the document’s own end date or condition is reached.
One key distinction, everywhere: a durable Power of Attorney keeps working if the principal becomes incapacitated; a non-durable one ends at incapacity. Whether yours is durable is stated in the document itself.
