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). The Act took effect March 22, 2012, but it is not limited to documents signed after that date. Under RC 1337.64, sections 1337.21 to 1337.64 apply to a power of attorney created before, on, or after the effective date, so an older Ohio POA is generally read under the same framework.

Two limits apply. The Act does not affect an act done before March 22, 2012, and a court may decline to apply it to a judicial proceeding begun before that date if doing so would substantially interfere with the proceeding or prejudice a party's rights. Separately, RC 1337.59 provides that a POA executed on or after March 29, 2006 and before the Act's effective date that used the former statutory form, or incorporated powers from former RC 1337.20, has those granted powers construed under that former section.

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. Ohio law adds one qualification that matters in practice: under RC 1337.30(D), termination is not effective as to an agent who, without actual knowledge of the death, acts in good faith under the power of attorney, and that act binds the principal and the principal's successors in interest. Once the agent knows the principal has died, the authority is gone.

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 governed by RC 1337.26(C). A power of attorney executed outside Ohio is valid here if, when it was executed, the execution complied with the law of the jurisdiction that determines the document's meaning and effect under RC 1337.27, or with the requirements for a military power of attorney under 10 U.S.C. 1044b.

That governing jurisdiction is not automatically the state where the document was signed. Under RC 1337.27, meaning and effect are determined by the law of the jurisdiction the document indicates, and only if the document indicates none does the law of the place of execution control. A POA drafted in another state but designating Ohio law is therefore measured against Ohio's execution rules.

What an Ohio Agent Can and Cannot Do

Agent Duties

Under RC 1337.34, an agent who has accepted appointment owes two different sets of duties, and the distinction matters when you are drafting or reading a document. Division (A) applies notwithstanding any provision in the power of attorney. Division (B) opens with "except as otherwise provided in the power of attorney," so the document can alter or waive those duties.

Mandatory duties under RC 1337.34(A), which the document cannot waive:

• 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.
• Act only within the scope of authority granted in the power of attorney.
• Attempt to preserve the principal's estate plan to the extent actually known, if preservation is consistent with the principal's best interest.

Default duties under RC 1337.34(B), which apply unless the power of attorney provides otherwise:

• Act loyally for the principal's benefit.
• Act so as not to create a conflict of interest that impairs the agent's ability to act impartially in the principal's best interest.
• Act with the care, competence, and diligence ordinarily exercised by agents in similar circumstances.
• Keep a record of all receipts, disbursements, and transactions made on behalf of the principal.
• Cooperate with the person who has authority to make health care decisions for the principal, to carry out the principal's reasonable expectations to the extent actually known and otherwise act in the principal's best interest.

Record-keeping is the duty agents most often overlook. It sits in division (B), so a carefully drafted POA can relax it, but a document that says nothing leaves the agent responsible for a full transaction record.

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 continue to act once the agent knows the principal has died, 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 1337.14, the principal may revoke the designation of the attorney in fact at any time and in any manner. Revocation takes effect when the principal expresses the intent to revoke, with one exception: if the attending physician was made aware of the health care POA, revocation is effective once it is communicated to that physician by the principal, by a witness to the revocation, or by health care personnel to whom the principal communicated it. The physician must then make that fact part of the principal's medical record.

RC 1337.14 also settles two follow-on questions. Unless the document says otherwise, a later valid health care POA revokes an earlier one. And a declaration for mental health treatment under RC Chapter 2135 does not revoke a health care POA, but it does supersede it as to mental health treatment.

A related section is easy to confuse with this one: RC 1337.17 does not state the revocation rule. It governs printed health care POA forms sold or distributed in Ohio for use by adults who are not advised by an attorney, and prescribes the notice text those forms must carry.

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 becomes incapacitated, if the power of attorney is not durable.
• 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 of an agent's authority or of the power of attorney is not effective as to the agent, or as to another person, that acts in good faith under the POA without actual knowledge of the termination, and such an act binds the principal and the principal's successors in interest. RC 1337.30(D) names the agent first, so this protection is not limited to the banks, title companies, and other third parties that honor a POA without knowing it has been revoked.
