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

Ohio adopted the Uniform Power of Attorney Act (UPOAA) as Ohio Rev. Code sections 1337.21 through 1337.64. Under that framework, a financial power of attorney is durable by default: it remains valid even if the principal later loses capacity, unless the document expressly provides otherwise. Execution requires a principal signature, and notarization makes that signature presumptively genuine. Medical decisions are handled under a separate, older statute: the durable power of attorney for health care, RC 1337.11-1337.17, which has its own execution and witness requirements.

What a Power of Attorney Does in Ohio

A power of attorney is a written document in which a principal grants an agent authority to act on the principal's behalf in legal, financial, or personal matters. The scope of that authority depends entirely on what the document specifies: it can be broad, covering virtually all financial and legal affairs, or narrow, authorizing only a single transaction.

Ohio recognizes general POAs, limited POAs, and durable POAs under the UPOAA (RC 1337.21-1337.64). All financial powers of attorney executed in Ohio on or after March 22, 2012 fall under that framework.

An agent under an Ohio POA is a fiduciary. The agent must act in the principal's best interest and in accordance with the principal's known wishes. That relationship is not optional: once a person accepts an agent role, the duties attach.

A POA ends automatically when the principal dies. From that point, the personal representative of the estate controls the principal's property. An agent has no authority to act after the principal's death.

Durable Power of Attorney in Ohio (Durable by Default Under the UPOAA)

Ohio's most significant rule for financial POAs is that durability is the default. Under RC 1337.24, a power of attorney created under sections 1337.21 to 1337.64 is durable unless it expressly provides that it is terminated by the incapacity of the principal.

That default matters enormously in practice. In states without a durability default, a POA automatically lapses when the principal becomes incapacitated, which is precisely when the agent's help is most needed. Ohio's rule reverses that: the POA survives incapacity unless the principal opts out.

Ohio also recognizes springing POAs. Under RC 1337.29, a power of attorney may be made effective at a future date or upon the occurrence of a future event or contingency. If a POA is made contingent on a finding of incapacity, the principal may specify who makes that determination. This is the opposite of Florida's approach, which bars springing POAs.

If the principal later regains capacity, a previously incapacitated principal who drafted a springing POA conditioned on incapacity may revoke it once competent. The document can address that scenario explicitly.

How to Create a Valid Ohio Power of Attorney

RC 1337.25 governs execution of a financial power of attorney in Ohio. The requirements are straightforward:

Signature. The POA must be signed by the principal, or in the principal's conscious presence by another individual directed by the principal to sign the principal's name on the document.

Notarization (recommended, not strictly required for validity, but creates presumption). A signature on a power of attorney is presumed to be genuine if the principal acknowledges the signature before a notary public or other individual authorized by law to take acknowledgments. Notarization is the practical standard because third parties such as banks and financial institutions routinely require it before honoring a POA.

Witnesses. RC 1337.25 does not require witnesses for a financial power of attorney. This contrasts with Ohio's health care POA, discussed below, which does require either notarization or two adult witnesses.

Statutory form. Ohio provides an optional statutory form at RC 1337.60. Using the statutory form is not required, but documents that substantially conform to it are valid. The form contains a plain-English explanation of each power being granted, which can help both principals and agents understand the scope of authority.

Out-of-state POAs are recognized in Ohio if they were validly executed under the law of the state where they were created, under RC 1337.27.

What an Ohio Agent Can and Cannot Do

Agent Duties

Under RC 1337.34, an agent who has accepted appointment must:

• Act in accordance with the principal's reasonable expectations to the extent actually known, and otherwise in the principal's best interest.
• Act in good faith and only within the scope of authority granted.
• Avoid conflicts of interest that would impair impartial judgment.
• Attempt to preserve the principal's estate plan to the extent actually known, if preservation is consistent with the principal's best interest.

An agent is not required to disclose receipts, disbursements, or transactions unless ordered by a court or requested by the principal, a guardian, a conservator, or other authorized persons. If a proper request is made, the agent must comply within thirty days or provide a written explanation of why additional time is needed and then comply within an additional thirty days.

Hot Powers Requiring an Express Specific Grant

Certain high-stakes actions may not be taken by an agent unless the power of attorney expressly authorizes each one. Under RC 1337.42, these powers requiring a specific grant include:

• Create, amend, revoke, or terminate an inter vivos trust (to the extent permitted under Ohio trust law, RC Title LVIII).
• Make a gift (subject to the limits in RC 1337.58, which ties gifting authority to the annual federal gift tax exclusion unless the POA states otherwise).
• Create or change rights of survivorship in property.
• Create or change a beneficiary designation.
• Delegate authority granted under the power of attorney.
• Waive the principal's right to be a beneficiary of a joint and survivor annuity, including a survivor benefit under a retirement plan.
• Exercise fiduciary powers the principal has authority to delegate.

An agent who is not an ancestor, spouse, or descendant of the principal faces an additional restriction: absent express authorization, that agent may not create in themselves (or in someone to whom the agent owes a support obligation) any interest in the principal's property, whether by gift, survivorship right, beneficiary designation, or disclaimer.

These limitations protect principals from overreaching. An agent who exercises a hot power without specific written authorization may face personal liability.

What the Agent Cannot Do

Regardless of what the POA says, an agent may not make medical or health care decisions under a financial POA: that authority requires a separate health care POA under RC 1337.11-1337.17. An agent also cannot act after the principal's death, cannot make or change a will on the principal's behalf, and cannot act in ways that benefit the agent at the principal's expense unless the document expressly permits it.

Health Care Power of Attorney in Ohio

Ohio separates financial and medical decision-making into two entirely different statutes. A financial POA under RC 1337.21-1337.64 does not authorize an agent to make health care decisions.

Medical decision-making authority is granted through the durable power of attorney for health care, governed by RC 1337.11 through 1337.17. The appointed individual is called the attorney in fact (not agent).

Execution Requirements for the Health Care POA

RC 1337.12 sets out strict execution requirements. A durable power of attorney for health care must:

• Be signed at the end of the instrument by the principal, stating the date of execution.
• Be either (A) acknowledged before a notary public, who must also certify that the principal appears to be of sound mind and not under duress, fraud, or undue influence, OR (B) signed by at least two adult witnesses who were present when the principal signed.

Witness disqualifications. The following persons may not serve as witnesses: anyone related to the principal by blood, marriage, or adoption; the attorney in fact designated in the document; the principal's attending physician; the administrator of any nursing home where the principal is receiving care.

When the Health Care POA Takes Effect

Under RC 1337.13, the attorney in fact under a health care POA may make health care decisions for the principal only if the attending physician determines that the principal has lost the capacity to make informed health care decisions. At that point, the attorney in fact holds authority to the same extent the principal would have if still competent.

Under RC 1337.17, the principal retains the right to revoke the designation of the attorney in fact at any time, in any manner, including by expressing the intent to revoke to the attending physician or health care provider. Revocation is generally effective when the principal communicates it.

If a principal wants both financial and medical authority covered, two separate documents are required: a durable financial POA under RC 1337.21-1337.64 for property and financial affairs, and a durable health care POA under RC 1337.11-1337.17 for medical decisions.

Revoking or Ending an Ohio Power of Attorney

A competent principal may revoke a financial POA at any time. Ohio law does not require a specific form for revocation. The principal may revoke in writing, by oral communication to the agent, or by executing a new POA that expressly revokes prior ones.

For a POA that was recorded (for example, one used to convey real property), the revocation must also be recorded in the same county recorder's office where the original POA was recorded, under RC 1337.05.

Under RC 1337.30, a power of attorney terminates automatically when:

• The principal dies.
• The principal revokes the POA.
• The POA provides that it terminates on a specific date or occurrence and that event happens.
• The purpose of the POA is accomplished.
• The agent's authority terminates and no successor agent is named.

An agent's authority terminates separately when: the principal revokes the agent's authority; the agent dies, becomes incapacitated, or resigns; or, if the agent was the principal's spouse, an action for divorce, dissolution, annulment, or legal separation is filed (unless the POA provides otherwise).

Termination is not effective against a third party who, without actual knowledge of the termination, acts in good faith in reliance on the POA. This good-faith protection shields banks, title companies, and other third parties from liability when they honor a POA without knowledge that it has been revoked.
