Delaware Power of Attorney Laws: Durable, Medical, and Financial POA (2026)

A power of attorney (POA) is one of the most important legal documents a Delaware resident can create. It lets you name a trusted person, called an agent or attorney-in-fact, to handle financial, legal, or medical decisions on your behalf. Delaware has two separate legal frameworks: the Durable Personal Powers of Attorney Act (12 Del. C. ch. 49A) for financial and property matters, and the Uniform Health-Care Decisions Act (16 Del. C. ch. 25) for medical decisions. Understanding which law applies, and how to execute each document correctly, protects you and the people you trust.

What a Power of Attorney Does in Delaware

A power of attorney is a written authorization that lets your agent act in your place for purposes spelled out in the document. Agents can conduct real estate transactions, manage bank accounts, file taxes, operate a business, manage investments, and handle dozens of other financial and legal matters, but only to the extent the document expressly grants that authority.

Delaware law draws a firm line between personal (financial) powers of attorney under Title 12 and health-care powers of attorney under Title 16. A single document cannot serve both purposes. You need separate instruments if you want an agent for both finances and medical care.

A Delaware POA gives the agent only the powers the principal grants. Courts in Delaware have consistently held that ambiguities in a POA are construed narrowly against the agent, so a carefully drafted document protects everyone involved.

Durable Power of Attorney in Delaware

Under 12 Del. C. 49A-104, a power of attorney is durable only if it contains express durability language, such as:

"This power of attorney shall not be affected by the subsequent incapacity of the principal."

or

"This power of attorney shall become effective upon the incapacity of the principal."

Without one of these phrases or similar words showing that same intent, the POA is not durable and terminates automatically if the principal becomes incapacitated. This is a critical planning point: a non-durable POA is useless precisely when most people need an agent the most.

A POA can also be springing, meaning it takes effect only upon incapacity. Under 12 Del. C. 49A-109, a springing POA becomes effective when a physician, or the Court of Chancery, makes a written determination that the principal lacks capacity. Otherwise, a POA is effective immediately upon execution unless the principal designates a future date or triggering event.

Delaware also still maintains the older Chapter 49 for powers of attorney executed before the Chapter 49A effective date. New documents should be drafted under Chapter 49A.

How to Create a Valid Delaware Power of Attorney

Delaware imposes a distinctive three-part execution requirement under 12 Del. C. 49A-105. A personal power of attorney must be:

1. In writing
2. Signed by the principal (or by another person in the principal's presence and at the principal's express direction)
3. Dated
4. Signed in the presence of a notarial officer (notary public or other authorized officer)
5. Signed in the presence of one adult witness who is neither related to the principal by blood, marriage, or adoption, nor entitled to any portion of the principal's estate under an existing will, codicil, trust, or similar instrument

The witness must be a disinterested adult. A spouse, child, or heir named in the principal's will cannot serve as a witness. This one-witness requirement is specific to Delaware and differs from states that require two witnesses or no witness at all.

An agent must also sign an agent certification before exercising any authority. Under 12 Del. C. 49A-105(c), an agent has no authority to act unless the agent has first executed and affixed to the power of attorney a certification stating that the agent will act in the principal's best interests, in good faith, and only within the scope of authority granted. The statutory form of the certification appears at 12 Del. C. 49A-301. Separately, under 12 Del. C. 49A-105(b), if the document is not accompanied by a signed notice to the principal placed at the beginning of the instrument, any person challenging the agent's authority may require the agent to demonstrate that the power of attorney is valid.

Delaware provides an optional statutory form that principals may use. Departing from the statutory form does not invalidate the document, but the form ensures all required elements are present.

What a Delaware Agent Can and Cannot Do

General Financial Authority

When a principal grants general authority, the agent may manage real property, tangible personal property, bank accounts, stocks and bonds, business operations, insurance, retirement plans, taxes, claims and litigation, and personal and family maintenance matters, among others (12 Del. C. 49A-201(a) and 49A-203 through 49A-216).

Hot Powers Requiring Specific Written Authorization

Certain actions carry significant risk of harm to the principal's estate. Under 12 Del. C. 49A-201(b), these powers are only valid if the POA expressly and specifically grants each one:

• Creating, amending, revoking, or terminating an inter vivos trust
• Making gifts
• Creating or changing rights of survivorship
• Creating or changing a beneficiary designation on a financial account or insurance policy
• Delegating the agent's authority to another person
• Exercising fiduciary powers the principal holds
• Disclaiming, renouncing, or releasing interests in an estate or trust
• Exercising rights under Delaware's Fiduciary Access to Digital Assets and Digital Accounts Act

A general grant of financial authority does not carry these hot powers automatically. Each one requires its own written authorization in the document.

What the Agent Cannot Do

An agent acting under a financial POA has no authority over health-care decisions, cannot act after the principal's death (the estate passes to a personal representative), cannot make a new will or change an existing one on behalf of the principal, and cannot act in ways that violate the agent's fiduciary duties under 12 Del. C. 49A-114. An agent must act in the principal's best interest, avoid conflicts of interest, maintain records, and cooperate with health-care agents on decisions affecting the principal's care.

Third-Party Acceptance

Under 12 Del. C. 49A-119, a person who accepts an acknowledged POA in good faith is protected from liability even if the document later proves defective or terminated, provided they had no actual knowledge of the problem. Conversely, under 12 Del. C. 49A-120, a third party such as a bank that wrongfully refuses a valid acknowledged POA may be held liable for the principal's attorney fees, costs, and damages caused by the refusal.

Advance Health-Care Directive in Delaware

Delaware's medical POA and living will are governed by a completely separate statute: the Uniform Health-Care Decisions Act, 16 Del. C. ch. 25. The instrument is called an Advance Health-Care Directive and can include a health-care instruction (living will), a power of attorney for health care naming an agent, or both in the same document.

What the Health-Care Agent Can Do

Under 16 Del. C. 2508 and 2518, a health-care agent may make any health-care decision the principal could make, including consenting to or refusing treatment, selecting or discharging health-care providers, and making decisions about end-of-life care, subject to any limits the principal writes into the directive.

Execution Requirements

A power of attorney for health care under 16 Del. C. 2508(d) must be:

• In a written record
• Signed by the individual creating the power
• Witnessed by one adult witness who reasonably believes the act is voluntary and knowing

The witness cannot be the named agent or the agent's spouse, domestic partner, or cohabitant. If the principal is a resident of a nursing home or long-term care facility, the witness cannot be an owner, operator, employee, or contractor of that facility. That family-member exception applies under 16 Del. C. 2508(b)(2) to who may serve as agent, not to witnesses.

No notary is required for a health-care advance directive, unlike the financial POA. Remote witnessing is permitted under 16 Del. C. 2508(e) if the witness can observe the signing in real time via audio-visual electronic means.

Revocation of an Advance Directive

Under 16 Del. C. 2515, a principal can revoke an advance directive at any time, in any manner communicating the intent to revoke, unless a court has found the principal lacks capacity to do so or another capacity-related exception under 2515(a) applies. Revocation is effective when the principal's health-care provider receives notice.

Revoking or Ending a Delaware Power of Attorney

A financial POA under Chapter 49A ends in several ways (12 Del. C. 49A-110):

• Principal's death: the POA terminates immediately and the agent has no further authority
• Revocation by the principal: must be communicated to the agent and relevant third parties; no specific form is required, but a written signed revocation is strongly recommended
• Occurrence of a terminating event stated in the document itself
• Purpose accomplished: if the POA was granted for a specific task, authority ends when that task is complete
• Agent's death, incapacity, or resignation: authority ends if no successor agent is named
• Court order: the Court of Chancery may revoke a POA

A new POA does not automatically revoke a prior one unless the new document expressly states that it does. To avoid confusion, the new document should include an explicit revocation clause.

Importantly, a non-durable POA also ends automatically when the principal becomes incapacitated. A durable POA survives incapacity but still ends at death.
