Utah Health Care Surrogate Rules: Who Decides When There's No Directive

When a parent is rushed to the hospital and hasn't signed an advance health care directive, someone still needs to consent to treatment. Utah doesn't leave this to guesswork — the 2026 Uniform Health Care Decisions Act (Utah Code Title 75A, Chapter 9) establishes a default surrogate priority list for a patient who lacks capacity and has no available agent or guardian authorized to make health care decisions.

The Default Surrogate Priority Order

Under Section 75A-9-111, when a patient lacks capacity, medical providers turn to the following classes, in descending order, if the person is reasonably available and not disqualified:

1. An adult the patient identified (other than in a health-care power of attorney) to make a health-care decision if the patient cannot
2. Spouse, unless a listed divorce, annulment, dissolution, legal-separation, or desertion condition applies
3. Adult child or parent of the patient (the same priority class)
4. Cohabitant
5. Adult sibling
6. Adult grandchild or grandparent (the same priority class)
7. Adult who routinely assisted with supported decision-making during the preceding six months
8. Adult stepchild whom the patient actively parented during the stepchild's minor years and with whom the patient has an ongoing relationship
9. Other adult who has exhibited special care and concern and is familiar with the patient's personal values
10. A physician designated by the responsible health care professional under the statute, after best efforts cannot identify and locate an earlier class and the required medical-ethics consultation

If multiple people share the same priority class — for example, three adult children — the healthcare provider can follow the decision of a majority of the members of the highest-priority class who have communicated their views and are acting consistently with their statutory duties.

How Emergency Decisions Work

In a genuine emergency — the patient's life is at immediate risk and delay could cause serious harm — physicians can proceed with medically necessary treatment without surrogate consent. This is standard medical ethics backed by Utah law: the physician's duty to preserve life overrides the consent requirement when there's no time to locate a surrogate.

Outside emergencies, the default surrogate system gives the highest-priority available person authority to consent to or refuse treatment, request transfer, and access medical records. The authority continues while the statutory conditions are met; a responsible health care professional may recognize the next person in priority if the current surrogate cannot or will not perform the required duties.

Where the System Breaks Down

The default surrogate statute works well for straightforward decisions — consent to surgery after a hip fracture, agree to a course of antibiotics, authorize a discharge plan. It starts failing in three common situations:

Sibling disagreement. When adult children disagree about a parent's care — one wants aggressive treatment, another wants comfort care — the hospital faces a majority-decision situation that can fracture families. The statute provides a tiebreaker mechanism, but hospitals are understandably reluctant to act on a 2-to-1 vote about end-of-life care. They may request court intervention instead.

Long-term care decisions. Default surrogacy covers acute medical decisions, but it doesn't give you authority to sign an assisted living admission agreement, manage finances to pay for care, or negotiate with Medicaid on your parent's behalf. Those require a power of attorney or guardianship.

Facility-level complications. Some facilities — particularly skilled nursing facilities accepting a post-hospital transfer — want documentation beyond the default surrogate statute. They may ask for a power of attorney or formal guardian letters before admitting a patient whose family member is acting under default surrogate authority alone.

Why an Advance Directive Is Still Better

Default surrogacy is the safety net, not the plan. An advance health care directive under the 2026 law gives your parent three advantages the default statute doesn't:

• Specific treatment instructions. Your parent can state whether they want life-sustaining treatment, artificial nutrition, or pain management only. Default surrogates guess at what the patient would have wanted.
• Named agent with clear authority. The directive removes ambiguity about who decides. No priority list, no majority votes among siblings.
• Portability. A written directive travels with the patient. Default surrogacy depends on the hospital identifying and contacting the right family member.

Under the 2026 Uniform Health Care Decisions Act, executing a directive that names a healthcare agent requires only the declarant's signature and one disinterested adult witness — no notary needed. If the directive contains only treatment instructions without naming an agent, even the witness requirement drops away; the declarant's signature alone is sufficient.

The Utah Power of Attorney & Guardianship Kit covers both the advance directive (healthcare decisions) and the durable power of attorney (financial decisions), so you're not relying on default rules when a crisis hits.
