A medical power of attorney in Ohio is a signed legal document in which a principal names an agent to make health care decisions on the principal’s behalf if the principal becomes unable to communicate those decisions. Ohio calls this document a durable power of attorney for health care, governed by R.C. 1337.11 through 1337.17. The agent’s authority begins only when a doctor determines the principal cannot make or communicate health care decisions.

What Is a Medical Power of Attorney in Ohio?
An Ohio medical power of attorney is a written instrument, signed by the principal, that appoints a health care agent, sometimes called an attorney in fact for health care, to make medical decisions when the principal cannot make them personally. The principal names the agent. The statute defines the agent’s authority. A signed medical power of attorney creates a legal relationship between principal and agent for health care decisions.
Ohio’s version of this document sits in Ohio Revised Code Chapter 1337, sections 1337.11 through 1337.17, sometimes called the durable power of attorney for health care law. The word “durable” means the document remains effective even after the principal becomes incapacitated, which is the opposite of how authority under some other legal instruments can lapse once a person can no longer manage their own affairs.

How Do You Get a Medical Power of Attorney in Ohio?
To get a medical power of attorney in Ohio, the principal signs a written document naming a health care agent, then has the signature either witnessed by two eligible adults or acknowledged before a notary public, following the execution rules in R.C. 1337.12. A person related to the principal, the named agent, the principal’s attending physician, or a nursing home administrator caring for the principal may not serve as a witness.
R.C. 1337.12 requires the principal to sign and date the instrument. If the document is witnessed rather than notarized, both witnesses must sign after the principal and attest that the principal appeared to be of sound mind and free from duress, fraud, or undue influence. The witnesses and the principal do not need to sign the same physical page. Because the eligible-witness rules exclude close family and the named agent, many Ohio families choose notarization instead of relying on lay witnesses.

When Does an Ohio Medical Power of Attorney Take Effect?
An Ohio medical power of attorney takes effect when the principal’s attending physician determines, and documents, that the principal cannot make or communicate informed health care decisions. Until that determination, the principal continues to make personal medical decisions and the agent has no authority to act.
This trigger is a clinical determination, not a fixed date. If the principal regains the capacity to communicate health care decisions, whether after surgery, sedation, or a temporary medical crisis, decision making authority returns to the principal, and the agent’s authority to act again pauses until incapacity recurs.

What Can the Health Care Agent Do?
Under R.C. 1337.13, an Ohio health care agent may generally consent to, refuse, or withdraw medical treatment, choose or change health care providers and facilities, and access the principal’s medical records once the agent’s authority is active. The principal may broaden or narrow this authority in the document itself.
A properly drafted Ohio medical power of attorney typically authorizes the agent to:
- Consent to, refuse, or withdraw medical treatment on the principal’s behalf
- Select, admit to, or discharge the principal from a hospital, nursing facility, or other care setting
- Hire or dismiss medical personnel involved in the principal’s care
- Review and receive the principal’s protected health information under HIPAA, 45 C.F.R. Part 164
- Make decisions about life-sustaining treatment within any limits the principal wrote into the document
The principal decides how broad or how limited this authority will be. Some principals place express limits on certain end-of-life decisions inside the document itself; others grant broad authority and rely on conversations with the agent to guide judgment calls when a situation the document did not anticipate comes up.

How Is a Medical Power of Attorney Different from a Living Will?
A medical power of attorney names a person to decide; a living will states the principal’s own wishes about life-sustaining treatment in advance. The two documents answer different questions and typically work together rather than replacing one another in an Ohio incapacity plan.
Ohio’s living will is governed by R.C. Chapter 2133, the Modified Uniform Rights of the Terminally Ill Act. A living will applies specifically when the principal is in a terminal condition or a permanently unconscious state, as those terms are defined in the statute, and it sets out the principal’s own written direction about life-sustaining treatment in that narrow circumstance. A medical power of attorney applies more broadly, to health care decisions generally, whenever the principal cannot communicate them. Many Ohio estate plans include both documents so the named agent has clear written guidance for the end-of-life scenarios the living will addresses, plus standing authority for the wider range of medical decisions the living will does not reach.
How Is a Medical Power of Attorney Different from a Financial Power of Attorney?
A medical power of attorney authorizes health care decisions. A financial power of attorney, governed separately under Ohio’s power of attorney statute, authorizes decisions about the principal’s money, property, and financial affairs. Ohio law treats these as two distinct instruments, and a principal typically signs both as part of a complete incapacity plan.
A principal can name the same person as both financial agent and health care agent, or split the roles between two different people. Splitting the roles is common where one family member has the financial background for account management and bill paying, and another has the availability or medical judgment better suited to hospital and treatment decisions.

What Happens Without a Medical Power of Attorney in Ohio?
Without a signed medical power of attorney, no one holds automatic, comprehensive legal authority to make routine medical decisions for an incapacitated Ohio adult, and family members may need to work informally with providers or, in a dispute, ask a probate court to appoint a guardian. Ohio law does set a specific priority order, but only for consenting to withhold or withdraw life-sustaining treatment.
R.C. 2133.08 lists, in descending order, who may give that specific consent when a patient has no living will and no health care power of attorney: the patient’s court-appointed guardian, if one exists, then the spouse, then the patient’s adult children (or a majority of them), followed by other family members further down the statute’s list. This priority order applies to life-sustaining treatment decisions specifically, not to medical decisions in general, which is one reason a signed medical power of attorney matters even where the family gets along well: it names one agent with clear authority across the fuller range of health care decisions, not just the narrow end-of-life scenario the default statute covers.
How Do You Revoke a Medical Power of Attorney in Ohio?
A principal with capacity may revoke an Ohio medical power of attorney at any time under R.C. 1337.14. Revocation can happen by notifying the agent or a treating health care provider, by a signed and dated writing, or by executing a new medical power of attorney that supersedes the earlier one.
Because a health care provider may not know a revocation occurred unless someone tells them, principals who revoke or replace a medical power of attorney should notify the former agent, the principal’s physicians, and any hospital or facility holding a copy of the prior document. Keeping a signed, current original in an accessible place, and giving copies to the agent and primary care provider, reduces the chance an outdated document is relied on during a crisis.
Choosing a Health Care Agent
The person named as health care agent may be asked to make weighty decisions during a medical crisis, so the choice deserves real thought rather than a reflexive pick of the oldest child or the closest relative.
Factors that commonly matter in an Ohio family’s decision include:
- Alignment with the principal’s values: the agent should know, or be willing to learn, what the principal would want across a range of medical scenarios.
- Availability: the agent needs to be reachable and able to respond during a fast moving hospital situation; naming an alternate agent is standard practice.
- Geography: an agent who lives at a distance may face real practical limits during an urgent decision, even where that person is otherwise the natural first choice.
- Composure under pressure: health care decisions during a crisis carry emotional weight, and not every capable person wants, or is suited to, that role.
Family conversation about the choice, before a crisis arrives, is part of what makes the document work as intended.

Frequently Asked Questions
How do you get a medical power of attorney in Ohio?
A principal signs a written document naming a health care agent, then has the signature either witnessed by two eligible adults or notarized, following the execution rules in R.C. 1337.12. Family members, the named agent, the principal’s physician, and a treating nursing home administrator may not serve as witnesses.
When does an Ohio medical power of attorney take effect?
It takes effect when the principal’s attending physician determines and documents that the principal cannot make or communicate health care decisions. Before that determination, the principal keeps full decision making authority and the named agent has no power to act.
How long does a medical power of attorney last in Ohio?
An Ohio durable power of attorney for health care does not carry a fixed expiration date. It remains in effect once properly signed until the principal revokes it, the principal dies, or a document the principal signs later replaces it.
Can a medical power of attorney be revoked in Ohio?
Yes. Under R.C. 1337.14, a principal with capacity may revoke it at any time by notifying the agent or a health care provider, by a signed and dated writing, or by signing a new medical power of attorney. Telling the former agent and treating providers helps prevent an outdated document from being relied on later.
What happens if I don’t have a medical power of attorney in Ohio?
No single person automatically holds comprehensive authority over your medical decisions. R.C. 2133.08 sets a priority order, guardian, then spouse, then adult children, then other relatives, but only for consenting to withhold or withdraw life-sustaining treatment, not for medical decisions in general.
Is a medical power of attorney the same as a living will in Ohio?
No. A medical power of attorney names an agent to make health care decisions generally when you cannot. A living will, governed by R.C. Chapter 2133, states your own wishes about life-sustaining treatment specifically if you are terminally ill or permanently unconscious. Many Ohio plans use both.
