Hawaii Power of Attorney Agent Duties: What the Law Requires of You

Being named as an agent under a Hawaii power of attorney is not just a family favor — it is a legal appointment that carries fiduciary duties, personal liability, and strict standards of conduct under HRS Chapter 551E. If you have been asked to serve as someone's attorney-in-fact, here is exactly what the law requires.

The Four Core Fiduciary Duties

The moment you begin acting under a POA, you owe the principal four fundamental duties:

1. Good faith and best interests. You must act in accordance with the principal's reasonable expectations. If you do not know what they would want in a specific situation, you must default to acting in their best interests — not yours, not another family member's.

2. Loyalty and conflict avoidance. You cannot use the principal's assets for your own benefit. You cannot enter into transactions where your personal interests conflict with the principal's. If you are also a beneficiary of the principal's estate, every financial decision you make as agent is subject to heightened scrutiny.

3. Care and competence. You must handle the principal's affairs with the same level of diligence a reasonably prudent person would apply to their own finances. This does not require professional expertise, but it does require attention, organization, and informed decision-making.

4. Separate accounts. You must keep the principal's assets completely separate from your personal funds. Commingling — depositing the principal's money into your personal account, even temporarily — is a breach of fiduciary duty that can result in civil liability and, in extreme cases, criminal prosecution for elder financial abuse.

Record-Keeping Requirements

Hawaii law does not specify an exact record-keeping format, but the standard of care requires you to maintain detailed records of every transaction you execute on the principal's behalf:

• All income received (Social Security, pension, rental income, investment returns)
• All expenses paid (medical bills, mortgage, utilities, insurance premiums, care facility costs)
• All asset transfers (gifts, trust funding, property sales)
• All investment decisions (purchases, sales, rebalancing)

Keep receipts, bank statements, and written records of every decision and its rationale. If another family member or the court later demands an accounting, these records are your primary defense.

The Agent Certification Form

Under HRS Section 551E-52, financial institutions can require you to sign an Agent Certification before they will accept the POA. This is a sworn statement, signed under penalty of perjury, affirming that:

• The POA has not been revoked or terminated
• The principal is still alive
• Your authority as agent has not been altered or limited since the document was executed
• You are the person named as agent in the POA

Signing a false Agent Certification exposes you to criminal perjury charges. Never sign this form if the principal has died — your authority terminates immediately upon death, and any transaction you execute after that point is invalid and potentially fraudulent.

How to Sign Documents as Agent

Whenever you sign a document on the principal's behalf, you must disclose your fiduciary capacity. The correct signature format is:

[Principal's Full Name] by [Your Full Name] as Agent under Power of Attorney

Never sign using only your own name. A document signed without disclosing your agency capacity can create personal liability for you and confusion about whether the transaction was on behalf of the principal or yourself.

When Your Authority Ends

Your authority as agent terminates immediately when any of these occur:

• The principal dies
• The principal revokes the POA (and you receive notice of the revocation)
• You resign
• A court orders termination of the POA
• You become incapacitated (unless a successor agent is named)

The most critical point: your authority ends at the moment of the principal's death. You cannot pay funeral expenses, transfer assets, or close accounts after the principal passes away using the POA. Those responsibilities shift to the personal representative (executor) named in the will, or to the court-appointed administrator if there is no will.

If you execute a transaction after the principal's death — even something as simple as writing a check from their account to cover a medical bill — you may be personally liable for the amount and subject to claims from the estate's beneficiaries.

Protecting Yourself as Agent

Serving as agent carries real legal risk. Protect yourself by:

• Documenting every decision and the reasoning behind it
• Never making gifts to yourself unless the POA explicitly authorizes it with hot powers
• Getting a second opinion (from an attorney or accountant) before any large transaction
• Filing taxes on time — the agent is personally responsible for ensuring the principal's state and federal returns are filed
• Communicating regularly with other family members about major decisions — even though you are not legally required to, transparency prevents accusations of self-dealing

The Hawaii Power of Attorney Kit includes an agent instruction letter and record-keeping templates that help agents stay organized and legally protected.
