Default Health-Care Surrogate Priority in Indiana

Short answer Indiana gives an available guardian or court-appointed representative first proxy priority, followed by a spouse, adult child, parent, adult sibling, grandparent, adult grandchild, nearest other adult relative, qualifying friend, and religious superior. People at the same rank try to reach consensus; if they disagree, a majority of available people at that rank controls. A provider must make a reasonable inquiry for authorized decision makers.

Requirements one by one

When the default route opens

Under § 16-36-1-4(a), the attending physician's good-faith opinion about capacity matters for consent. Section 16-36-7-42(b) applies its proxy route when the person cannot consent and lacks an effective directive or the designated representative is unwilling, unable, or not reasonably available.

Care or setting covered

Under § 16-36-7-10, health-care decisions include consent, refusal, and withdrawal, including life-prolonging procedures and mental-health treatment unless the directive says otherwise. The proxy section does not confine the family ladder to a named kind of facility.

Guardian, family, and nonfamily order

Under § 16-36-7-42(c), the order starts with a judicial guardian or court-appointed representative, then spouse, adult child, parent, adult sibling, grandparent, adult grandchild, and nearest other adult relative. An adult friend who kept regular contact and knows the person's activities, health, and religious or moral beliefs comes next. A member of a religious order may be represented by that person's religious superior after those classes.

Decision within one class

Under § 16-36-7-42(f), people at the same priority level make a reasonable effort at consensus. If they disagree, the majority of available people at that level controls. The statute does not give one adult child a veto over the others.

Who is available and eligible

Section 16-36-7-42(c) moves to a lower class when a prior class lacks a reasonably available, willing, competent person. Under § 16-36-1-17, the provider examines records and personal effects and attempts contact with high-priority people. Under § 16-36-7-43, a specifically disqualified person, certain separated or divorcing spouses, a person under a no-contact order, and a person charged with a crime allegedly committed against the patient cannot serve as proxy.

Decisions limited or excluded

Under § 16-36-7-42(d)–(e), the proxy considers the person's expressed or implied intentions. Withholding or withdrawing life-prolonging procedures requires evidence that the person would have chosen it or, where reliable wishes are unavailable, that it serves the person's best interests. That is a special evidentiary condition, not a blanket bar on the decision.

No surrogate or disputed authority

Under § 16-36-1-8, a provider or interested person may ask probate court for a health-care decision or a representative when no authorized person is available, declines, or fails to act in the patient's best interest. The court may adjust notice and hearing if delay would seriously harm health.

What trips people up

The friend route follows relatives and has express contact and knowledge requirements under § 16-36-7-42(c)(9). A majority rule applies only among available people at the same priority level under subsection (f). A guardian's first place in the default list does not require creating a guardianship before another listed class may act.

Common questions

Can one of several adult children decide alone? They should reasonably seek consensus; if they disagree, a majority of available adult children controls under § 16-36-7-42(f).

Can a close friend act? Yes, at the friend rank if the statutory contact and knowledge tests are met and higher classes cannot act (§ 16-36-7-42(c)(9)).

How can a court appoint a decision maker? A provider or interested person may petition probate court under § 16-36-1-8 when its conditions are met.
