When someone can no longer make their own choices, the law recognizes several people who can make decisions for someone who lacks capacity: an agent named in a durable power of attorney, an agent named in a healthcare directive, a successor trustee of a living trust, a guardian or conservator appointed by a court, or a representative payee or fiduciary appointed by a federal agency. Which one applies depends on what documents the person signed while they still had capacity, what kind of decision needs to be made, and whether anyone has to go to court.
If They Planned Ahead
Advance planning keeps families out of court. Three documents do most of the work: a durable power of attorney for finances, a healthcare directive, and a revocable living trust. Each one appoints a different kind of decision-maker, and each has limits.
Agent Under a Durable Power of Attorney
A power of attorney lets one person (the principal) give another person (the agent) legal authority to handle financial and legal matters. The principal must have mental capacity when they sign it. The word “durable” is what makes it useful later. A standard power of attorney ends the moment the principal becomes incapacitated. A durable power of attorney includes language stating that the agent’s authority survives that loss of capacity. Without the durability language, the document becomes useless at the exact moment it’s needed.
A durable power of attorney can take effect two ways. An immediate power of attorney is active from the moment it’s signed. A springing power of attorney sits dormant until a triggering event, usually a physician’s written determination that the principal is incapacitated. Springing versions reassure principals who don’t want anyone touching their finances while they’re still competent, but they can slow things down when the agent needs to act and the doctor’s certification isn’t yet in hand.
The document itself defines what the agent can do. Broad powers typically cover paying bills, managing bank accounts, handling investments, filing tax returns, and dealing with real estate. Certain high-risk actions require an explicit, specific grant of authority. Under the Uniform Power of Attorney Act, which a majority of states have adopted in some form, an agent cannot make gifts of the principal’s money, change beneficiary designations, create or modify trusts, or waive the principal’s interest in property unless the document expressly authorizes those actions. Every agent has a duty to act in the principal’s best interest and keep clear records. A financial power of attorney does not authorize medical decisions.
Agent Under a Healthcare Directive
Medical decision-making authority comes from a separate document, usually called a healthcare power of attorney or health care proxy. It must be signed while the person still has capacity. The agent has no authority to act until a physician determines the person can no longer make or communicate their own healthcare choices.
Once activated, the healthcare agent can consent to or refuse treatments, choose doctors and facilities, and make decisions about surgeries, medications, and rehabilitation. Many people pair the proxy with a living will spelling out specific preferences about life-sustaining treatments like mechanical ventilation or artificial nutrition. The agent is expected to follow those instructions, and where no specific instruction exists, to make the decision they believe the person would have made.
Under HIPAA’s Privacy Rule, a person authorized under state law to make healthcare decisions qualifies as the patient’s “personal representative.” Providers must treat the personal representative the same as the patient for purposes of accessing medical records and receiving relevant health information. In practice that means the healthcare agent can review lab results, speak with doctors, and get copies of records without separate HIPAA authorization forms, so long as the information relates to decisions within the scope of their authority.
Successor Trustee
Someone who creates a revocable living trust usually names themselves as the initial trustee and designates a successor to take over if they become incapacitated or die. The trust document usually specifies how incapacity is determined, often requiring one or two physicians to certify it. Once that certification is in hand, the successor trustee manages the trust assets.
There’s a critical limit. A successor trustee’s authority extends only to property titled in the name of the trust. A bank account, brokerage account, or piece of real estate that was never transferred into the trust remains outside the trustee’s control. For those assets, a durable power of attorney or a court-appointed conservator would still be needed. This gap is one of the most common reasons families end up in court even when a trust exists.
If They Didn’t Plan Ahead: Guardianship or Conservatorship
When someone loses capacity without having signed a power of attorney or healthcare directive, a court must appoint a decision-maker through a guardianship or conservatorship proceeding. State laws generally treat this as a last resort after less restrictive options have been considered.
The process begins when a concerned person, often a family member, files a petition asking the court to determine that the individual is incapacitated and needs a protected decision-maker. The court appoints professionals, typically a physician or psychologist, to evaluate the person’s condition. A hearing follows where the judge reviews the evidence, hears from interested parties, and decides whether to appoint a guardian, a conservator, or both.
Terminology varies by state. A guardian generally handles personal and medical decisions, including where the person lives and what healthcare they receive. A conservator manages financial matters like paying bills, investing assets, and maintaining property. One person can fill both roles, or the court can split the duties.
Who the Court Prefers to Appoint
Courts follow a statutory preference order. Details vary, but the general pattern places highest priority on anyone the person nominated in writing while still competent, such as a nomination inside a power of attorney. After that, courts typically prefer a spouse, then adult children, then parents, then other involved relatives. If no suitable family member is available or willing, the court may appoint a professional guardian or a public guardian’s office.
Limited Guardianship
Courts are not required to strip away all of a person’s decision-making rights. A limited guardianship restricts the guardian’s authority to only the areas where the court finds the person truly cannot manage, leaving the individual in control of everything else. Someone might lose the ability to manage complex finances but still be perfectly capable of choosing where to live or making routine medical decisions. State laws generally require courts to use the least restrictive form of intervention that adequately protects the person.
Costs, Bonds, and Ongoing Oversight
Guardianship proceedings are expensive. Court filing fees are relatively modest, but attorney fees for even an uncontested case can run several thousand dollars. Contested cases cost significantly more. The person’s estate usually pays, meaning the money comes from the very person the proceeding is meant to protect.
Courts in many states require conservators to post a surety bond as a financial guarantee against mismanagement, with the bond amount generally tied to the value of the estate’s assets plus anticipated annual income. Once appointed, guardians and conservators must file regular reports with the court, typically every year, covering the person’s living situation, health, and finances. Failure to file is one of the most common grounds for removal.
Emergency and Temporary Guardianship
Sometimes the standard timeline is too slow. If someone faces an immediate risk to their health, safety, or finances and no authorized decision-maker is in place, a court can appoint an emergency or temporary guardian on an expedited basis. The petitioner must show that waiting for a full hearing would expose the person to serious harm.
Emergency orders are deliberately short-lived, typically lasting 30 to 60 days, giving the court time to schedule a full hearing. The temporary guardian’s powers are usually narrower than a permanent guardian’s, limited to whatever actions are necessary to address the immediate crisis.
Government-Appointed Decision-Makers for Federal Benefits
Two federal programs appoint their own financial managers for beneficiaries who cannot handle their payments. These appointments happen independent of any state court proceeding and apply only to the specific benefits involved.
Social Security Representative Payee
When the Social Security Administration determines that a beneficiary cannot manage their own Social Security or SSI payments, it appoints a representative payee to receive and manage the funds. The beneficiary can suggest someone, and the SSA considers that preference, but the agency makes the final call on suitability.
The payee’s job is to use the benefits for the beneficiary’s basic needs like housing, food, clothing, and medical care, and to save anything left over. The authority does not extend beyond those government payments. A payee has no legal power over the person’s other bank accounts, property, or medical decisions. All payees must keep records of how funds are spent and make them available to the SSA on request.
A representative payee who knowingly diverts benefits to their own use faces a federal felony charge carrying up to five years in prison and fines. The court can order restitution, and a convicted payee is permanently barred from ever serving as a representative payee again. The SSA itself can revoke the appointment and redirect benefits to a new payee or to the beneficiary directly if it determines misuse has occurred.
VA Fiduciary
The Department of Veterans Affairs runs a separate fiduciary program for veterans and other VA beneficiaries who cannot manage their own financial affairs. The VA makes the determination based on medical documentation or an existing court finding of incapacity. The VA’s Fiduciary Hub then appoints a fiduciary, preferring someone the beneficiary chooses, such as a family member or friend.
Before appointment, the proposed fiduciary goes through a background investigation that includes a criminal records check, credit report review, and personal interview, plus a field examination that may include a face-to-face visit with the beneficiary. If the VA benefits in the fiduciary’s control will exceed $25,000, the fiduciary must obtain a surety bond within 60 days of appointment.
Changing or Removing the Decision-Maker
Legal authority over someone else’s life should never be permanent if circumstances change. The process for removing a decision-maker depends on how that person got their authority.
A principal who still has capacity, or who has regained it, can revoke a power of attorney at any time. The revocation should be in writing and, depending on the state, may need to be notarized. The principal should notify the agent, ideally by certified mail so there’s a record. If the original was filed with a government office like a county recorder, the revocation should be filed in the same place. Destroying the original with intent to revoke works in many states too, but written revocation with proper notice is far more reliable.
Removing a court-appointed guardian or conservator requires going back to the court that made the appointment. Any interested person, including the protected individual, family members, or even a concerned friend, can petition for removal. Common grounds include failure to file required reports, mismanagement of finances, neglect, or abuse. The court can also modify or terminate a guardianship if the person’s condition has improved, or if a less restrictive alternative has become available.
A Less Restrictive Alternative: Supported Decision-Making
Not every person who struggles with decisions needs someone else to decide for them. Supported decision-making lets individuals with disabilities or cognitive challenges make their own choices with help from trusted advisors they select. Instead of transferring authority to a guardian, the person keeps their legal rights and works with a support network of family, friends, or professionals to understand information, weigh options, and communicate decisions.
A growing number of states have enacted statutes formally recognizing supported decision-making agreements, giving them legal weight so banks, doctors, and other third parties will honor the arrangement. For families weighing guardianship, it’s worth asking whether this would be enough. Courts increasingly expect petitioners to explain why less restrictive alternatives won’t work before granting a full guardianship.
