Yes, you can have two healthcare proxies in most states, but naming co-agents is rarely the right choice. The Uniform Health-Care Decisions Act, which shapes the law in a majority of states, allows you to appoint more than one agent in a single document. The same Act’s own commentary discourages the practice because co-agents can disagree, deadlock, or give conflicting instructions to your medical team at the worst possible moment. The approach most estate planning attorneys recommend is naming one primary agent and one or more alternates who step in only if the primary cannot serve.
What the Law Allows
Under the default rule in states that follow the Uniform Health-Care Decisions Act, each co-agent you name can act independently unless your document says otherwise. You are free to change that default. You could require co-agents to reach consensus before any decision takes effect, let a majority rule when you name three, or divide authority so that each agent controls a specific category of decisions.1North Carolina General Assembly. Uniform Health-Care Decisions Act (2023)
So the question is not really whether the law permits two agents. It does. The question is whether two agents will serve you well when a doctor is standing at the bedside waiting for an answer.
Why Co-Agents Create Problems
The commentary to the Uniform Health-Care Decisions Act explicitly discourages appointing co-agents, and the reasoning holds up in practice. When each co-agent can act separately, two people may give the hospital opposing instructions on the same treatment. When co-agents must agree, they may fail to reach consensus, or the back-and-forth may delay care long enough to matter. In a medical emergency where minutes count, a deadlock between two equally authorized agents is exactly the situation your proxy is supposed to prevent.1North Carolina General Assembly. Uniform Health-Care Decisions Act (2023)
Family dynamics add another layer. Two adult children named as co-agents may have spent decades disagreeing about smaller things. A hospital room is not where those patterns tend to improve. Doctors facing split instructions sometimes refuse to act until the dispute is resolved, which can mean a court hearing in the middle of a crisis.
If You Still Want Two Agents, Build In a Tiebreaker
There are real reasons people want to name two agents. You may trust two children equally and worry that choosing one will cause lasting resentment. You may want a spouse and an adult child to share the responsibility. If you decide to go ahead, the document itself needs to answer the question of what happens when the agents disagree. Options include:
- Designating one co-agent as the final decision-maker when the two cannot agree.
- Naming three co-agents and requiring a majority.
- Splitting authority by subject matter, so one co-agent controls certain categories of decisions and the other controls the rest.
Without a clear tiebreaker written into the proxy, you are relying on two people to see eye-to-eye on every medical decision that comes up. That is a gamble, and the stakes are your care.
The Safer Structure: One Primary, One Alternate
Naming one primary agent and one or more alternates gives you the backup that most people are actually looking for when they ask about having two proxies. The alternate holds no authority while the primary is willing and able to serve. If your primary agent is traveling, unreachable, dealing with their own health crisis, unwilling to act, or has become incapacitated, the alternate steps in.2National Institute on Aging.

While serving, an alternate has the same authority the primary would have. Authority shifts back to the primary once that person is available again, unless the primary has permanently resigned or been disqualified.1North Carolina General Assembly. Uniform Health-Care Decisions Act (2023)
There is no universal cap on how many alternates you can name, but two or three is usually plenty. Past that, you are naming people you probably do not know well enough to trust with these decisions. The ordering matters: list the alternates in the sequence you want them to serve, so there is never a question about who takes over.
Choosing Between Two Candidates
If you are torn between two people and were considering naming both to avoid picking, think about who is better suited to the actual job rather than who you are closest to emotionally. The best agent is the person most likely to carry out your wishes under pressure, including pressure from other family members. The one you did not name as primary can serve as your alternate, which keeps them involved without creating a split authority problem.
Whoever you choose, a person must generally be at least 18 to serve, or 19 in Alabama and Nebraska. The American Bar Association recommends against naming your healthcare provider, their spouse, or their employees because those relationships create potential conflicts of interest.2National Institute on Aging.

What Happens If Neither Agent Can Serve
If you never named a proxy, or if your primary and all alternates are unavailable, most states fall back on a default surrogate hierarchy written into state law. The typical priority order is:
- Spouse or domestic partner
- Adult child
- Parent
- Sibling
- Other relatives, in some states
A growing number of states also allow a close friend to serve as a default surrogate. When multiple people share the same priority level, such as several adult children, most states prefer consensus, though some allow a majority decision or ask the group to designate one spokesperson. In states without default surrogate laws, family disagreements can create genuine barriers to treatment, sometimes requiring court intervention. Naming your own agents, in the order you want them to serve, avoids all of this.
Changing Your Mind Later
If you already have a proxy with two co-agents and want to switch to a primary-plus-alternate structure, or if you want to swap agents entirely, you can revoke a healthcare proxy at any time while you have the mental capacity to do so. Most states recognize several methods:
- A signed, dated written statement declaring that you revoke the proxy.
- Physical destruction of the original document.
- Oral revocation, though some states require a witness to the oral statement.
- Executing a new healthcare proxy, which automatically revokes any earlier one.
Revocation takes effect when you communicate it to your agent, your healthcare provider, or the facility where you are receiving care. This is the step people skip, and it causes real problems. If your old agents and your doctor do not know about the change, they will keep relying on the outdated document. Send written notice to everyone who has a copy, and ask your doctor’s office to replace the old proxy in your medical file.
One detail worth flagging: in many states, divorce automatically revokes the designation of a former spouse as your agent. Do not rely on that. If your marital status changes, sign a new proxy naming someone else.
