In Ohio, a power of attorney does not need to be notarized to be technically valid in every case, but the practical answer is close to yes. A financial POA that isn’t notarized will almost certainly be refused by banks and brokerages, a POA used for real estate must be notarized by law, and a healthcare POA has to be either notarized or signed in front of two qualified witnesses. Skipping notarization is legal on paper and a serious problem in practice.
Financial Powers of Attorney
Ohio’s Uniform Power of Attorney Act requires the principal to sign a financial POA, and it stops short of demanding notarization as a condition of validity. What the statute does instead is powerful enough that notarization becomes the practical standard. Under Ohio Revised Code 1337.25, when the principal acknowledges the signature before a notary public, the signature is presumed genuine.1Ohio Legislative Service Commission.

That presumption is what a bank, credit union, brokerage, or insurance company needs before it will let someone else move money or make decisions on the account holder’s behalf. With it, the institution has legal cover to rely on the document. Without it, the institution has no assurance that the signature is real and typically declines to act. The person holding an un-notarized POA can be entirely legitimate and still be turned away at the counter.
The notary’s role on a financial POA is limited: verify the signer’s identity and certify that the person acknowledged the signature. It is a standard notarial acknowledgment, not a mental capacity evaluation. That distinction matters because a healthcare POA notarization asks for more.
Healthcare Powers of Attorney
A healthcare POA in Ohio can be executed one of two ways: notarized, or signed in front of at least two qualified adult witnesses. Either method works on its own.2Ohio Legislative Service Commission. Ohio Revised Code Chapter 1337 – Power of Attorney – Section 1337.12
If a notary handles it, the attestation goes further than identity. The notary must also attest that the principal appears to be of sound mind and is not signing under duress, fraud, or undue influence.3Ohio Legislative Service Commission. Ohio Revised Code Chapter 1337 – Power of Attorney – Section 1337.12(C) That is a higher bar than what a financial POA acknowledgment requires.
Using witnesses instead is fine, but the witnesses must be disinterested. Ohio disqualifies several categories of people from serving:
- Anyone related to the principal by blood, marriage, or adoption
- The agent or any alternate agent named in the document
- The principal’s attending physician
- The administrator of any nursing home where the principal receives care
Each witness must watch the principal sign or hear the principal acknowledge the signature, and then sign the document to attest that the principal appears to be of sound mind and free from duress. The attending physician and nursing home administrators are also barred from being named as the agent, not just from witnessing. A healthcare facility employee can serve as agent only if related to the principal by blood, marriage, or adoption, or if both belong to the same religious order.4Ohio Legislative Service Commission. Ohio Revised Code Chapter 1337 – Power of Attorney – Section 1337.12(A)(2)
Medical Records Access
A healthcare POA can authorize the agent to see the principal’s medical records and protected health information immediately on execution, even before any loss of capacity. ORC 1337.12 permits this expressly. When the document is silent on records access, providers may limit what they share to only what the agent needs to make a specific treatment decision. Clear language in the document at signing avoids that limitation.
Real Estate Powers of Attorney
Notarization is not optional when a POA will be used to sell, mortgage, or lease real property. ORC 1337.01 requires such a POA to be signed and acknowledged with the same formalities as a deed.5Ohio Legislative Service Commission. Ohio Revised Code Chapter 1337 – Power of Attorney – Section 1337.01 ORC 5301.01 defines those formalities: acknowledgment before a notary public, judge, clerk of court, county auditor, county engineer, or mayor.6Ohio Legislative Service Commission. Ohio Revised Code 5301.01
The document also has to be recorded with the county recorder in the county where the property sits, and that recording must happen before the deed, mortgage, or lease signed under the POA is filed. If the POA wasn’t recorded first, it can still be recorded later as an attachment to a supporting affidavit, provided the POA itself was properly executed no later than the day the real property instrument was signed.7Ohio Legislative Service Commission. Ohio Revised Code Chapter 1337 – Power of Attorney – Section 1337.04
One drafting point worth flagging while you’re at the notary. Ohio’s statutory list of real property powers in ORC 1337.45(B) treats “sell” and “convey” as separate authorities. A POA that grants only the power to sell may not authorize the agent to actually transfer title. If a full transfer is the goal, the document should grant authority to both sell and convey.
Remote Online Notarization
The notary and the signer don’t have to be in the same room. Ohio permits remote online notarization under Ohio Administrative Code Rule 111:6-1-05. The notary must be physically in Ohio, but the signer can be anywhere in the United States, and outside the country under certain conditions.8Ohio Legislative Service Commission. Ohio Administrative Code Rule 111:6-1-05 – Requirements for Online Notarial Acts
The session runs over a live two-way audio-video connection. The notary verifies identity through personal knowledge, a government-issued photo ID reviewed by credential verification software, or a credible witness who knows the signer. Identity proofing with knowledge-based authentication questions is also required when the notary doesn’t personally know the signer. That makes remote notarization workable for a principal who is homebound, hospitalized, or living out of state.
What Happens if the POA Isn’t Properly Executed
An improperly executed POA gets treated as if it doesn’t exist at the moment the principal needs it most. Banks and title companies reject a financial POA without notarization because there is no presumption of genuineness for them to lean on. Medical providers disregard a healthcare POA that lacks either notarization or the required witnesses when treatment decisions have to be made.
If the principal has already lost mental capacity by the time the defect surfaces, the document can’t be repaired. A new one can’t be signed, and no notary can take an acknowledgment from someone who can’t give one. The family’s remaining option is a guardianship petition in probate court. In Franklin County, the filing fee alone for an adult guardianship application is $189, with additional hearing fees and background check costs on top. Attorney fees and court-appointed evaluator costs push the real total much higher. The process takes weeks or months, requires ongoing court oversight and annual reporting, and the court may appoint someone the principal would never have chosen. Notarization at signing avoids all of it.
