A conservator can make medical decisions for the person under their care, but only when the court’s appointment order specifically grants healthcare authority, and even then some high-stakes procedures require going back to court for separate approval. The scope depends entirely on what the judge wrote into the order. Some states use “guardian of the person” for the same role, but the function is identical.
Only a Conservator of the Person Has Medical Authority
Courts split conservatorship into two distinct roles. A conservator of the estate handles finances — bank accounts, bills, property — and carries no authority over healthcare at all. A conservator of the person handles daily life and well-being: where the conservatee lives, what they eat, and, when the order says so, what medical care they receive. One person can hold both roles, but medical decision-making power travels only with the “of the person” designation, and only when the court order includes it.
Terminology varies. Many states say “guardian” where others say “conservator.” The person-versus-estate split exists almost everywhere; just the labels change.
What Routine Medical Decisions a Conservator Can Make
A conservator of the person whose order includes healthcare authority can consent to the same range of care any competent adult would decide for themselves. That covers choosing doctors, agreeing to surgery or diagnostic tests, authorizing hospital admission, managing prescriptions, and arranging rehabilitative or ongoing care.
Two standards govern how those decisions get made. Under “substituted judgment,” the conservator applies the conservatee’s own known values and preferences — for example, honoring a religious objection to blood transfusions even if the conservator disagrees personally. When those preferences are unknown, the conservator falls back on “best interest,” meaning what a reasonable person would choose under the circumstances. The job is to stand in the conservatee’s shoes, not to impose the conservator’s values.
Under federal privacy law, a person with legal authority to make healthcare decisions for someone else qualifies as that person’s “personal representative” and can access medical records from hospitals, doctors, and insurers.1eCFR. 45 CFR 164.502 – Uses and Disclosures of Protected Health Information That access is essential for informed decision-making.
Decisions That Require Separate Court Approval
Some procedures are serious enough that standard medical authority does not cover them. The conservator has to file a new petition, notify interested parties, and convince a judge the treatment is necessary. Specifics vary by state, but the following almost universally require prior court approval:
- Sterilization: permanently preventing the conservatee from reproducing.
- Psychosurgery: operating on the brain to treat a mental health condition.
- Electroconvulsive therapy: sometimes called ECT or “shock therapy,” used for severe depression and other psychiatric conditions.
- Experimental treatments: any drug, device, or procedure not yet approved through standard medical channels.
- Involuntary psychiatric placement: committing the conservatee to a locked mental health facility against their will.
The approval process is deliberately rigorous. The conservator must present clear and convincing evidence that the procedure serves the conservatee’s interests, and the court will appoint an attorney to represent the conservatee if one is not already in place. A judge will typically weigh whether less invasive alternatives exist before authorizing the treatment. The treating physician usually needs to provide testimony or a written report explaining why the procedure is necessary.
End-of-Life and Life-Sustaining Treatment
This is the most unsettled area in conservatorship law. Rules vary dramatically from state to state. A majority of states have no specific statutory language addressing whether a conservator can withdraw life support, refuse resuscitation, or stop artificial nutrition on their own. Among states that do address it, some require a court petition before withdrawing life-sustaining treatment; a smaller number allow the conservator to decide without judicial review.
Several states permit withdrawal of life support only when an existing advance directive provides evidence of the person’s prior wishes. Others require the original conservatorship order to explicitly grant end-of-life authority. Where the statute is silent, conservators are often left navigating case law and hospital ethics committees.
An advance directive, when one exists, almost always controls. It reflects what the person wanted while they still had capacity, and courts treat that as the strongest evidence of their wishes. A conservator who disagrees cannot simply override it. They would have to petition the court to set the directive aside, which is a high bar.
How Advance Directives and Healthcare Agents Rank Above a Conservator
A conservator does not operate in a vacuum. If the conservatee signed a healthcare power of attorney or living will before losing capacity, those documents carry significant weight and often outrank the conservator on medical questions.
A healthcare power of attorney names a specific agent to make medical decisions. In most states, that agent’s authority takes priority over a conservator’s for healthcare choices unless a court specifically strips the agent of power. A conservator of the person and a healthcare agent can coexist for the same individual, with the agent making medical calls and the conservator handling other aspects of personal care. When the two disagree, the agent’s judgment typically prevails unless a court intervenes. If a conservator believes the agent is acting against the conservatee’s interests, the remedy is a court petition, not unilateral override.
A living will provides written instructions about end-of-life treatment, such as whether the person wants to be kept on a ventilator or prefers comfort care only. When a valid living will exists, the conservator is bound to follow it and cannot revoke or override it without a court order.
These advance planning documents can sometimes eliminate the need for a conservatorship altogether. Courts generally prefer a person’s own prior arrangements to govern when possible.2U.S. Department of Justice. Guardianship – Less Restrictive Options
Rights the Conservatee Keeps
A conservatorship does not erase the conservatee’s legal standing, and this is probably the most misunderstood part of the arrangement. Unless the court specifically removed the right, a conservatee generally retains the ability to:
- Consent to or refuse medical treatment. Many courts do not strip this right without specific evidence that the person cannot make informed healthcare choices. A conservatorship over finances alone does not automatically remove the right to refuse a medical procedure.
- Object to the conservator’s decisions by raising concerns with their attorney, a court investigator, or the judge directly.
- Petition to change or end the conservatorship, including replacing the conservator or modifying their powers.
- Be consulted about decisions. Even when the conservator has medical authority, they are expected to inform the conservatee about decisions affecting their care and consider the conservatee’s wishes.
- Receive visitors, mail, and phone calls. Social isolation by a conservator can be grounds for removal.
The conservator’s duty runs both ways: act in the conservatee’s interest, and respect the conservatee’s dignity and preferences to the greatest extent their condition allows. Ignoring clearly expressed wishes without good reason is a failure of legal duty.
What Happens If a Conservator Oversteps
Court oversight continues after appointment. Reviews typically occur within the first year and periodically thereafter. A court investigator may interview the conservatee again, examine the conservator’s records, and report to the judge on whether the arrangement is still necessary and whether the conservator is performing adequately. Conservators are expected to keep detailed records of medical decisions: what treatment was authorized, which providers were chosen, and why.
A conservator is a fiduciary, legally bound to act solely in the conservatee’s interest. Courts have found that a conservator acting in accordance with a judge’s orders enjoys a degree of protection, since they are carrying out the court’s directives. But a conservator who acts outside the scope of their authority — consenting to treatment the court never authorized, or ignoring the conservatee’s known wishes — can be held personally liable for the resulting harm.
Anyone with a legitimate interest in the conservatee’s welfare can petition to remove a conservator. Common grounds include neglecting medical needs, isolating the conservatee from family, making decisions that serve the conservator rather than the conservatee, and failing to file required reports. Courts take these petitions seriously, and a pattern of poor decision-making is usually enough.
