Indiana Advance Directive vs Living Will: What's the Difference?

These two terms get used interchangeably in everyday conversation, but under Indiana law they mean different things — and the distinction matters for how your document gets interpreted at the hospital.

Before 2023: Separate Documents

Historically, Indiana used several separate legal documents for healthcare planning:

• A Healthcare Power of Attorney — naming someone to make decisions for you
• A Healthcare Representative (HCR) Appointment — a slightly different mechanism for the same purpose
• A Living Will Declaration — documenting your wishes about life-sustaining treatment if you're terminal
• A Life-Prolonging Procedures Declaration — the opposite of a living will, requesting maximum intervention

These existed as distinct legal instruments under different sections of Indiana Code. Families often had some but not all of them, creating gaps and contradictions.

After Senate Enrolled Act 204: One Unified Document

On July 1, 2021, Indiana enacted Senate Enrolled Act 204, which became fully mandatory on January 1, 2023. SEA 204 consolidated all of those separate documents into a single "Advance Directive for Health Care Decisions" under Indiana Code Section 16-36-7.

Under current law, an advance directive is the umbrella document. It can include:

• Healthcare Representative designation — naming the person who makes decisions when you can't
• Living will declaration — instructions to withhold or withdraw life-sustaining treatment if you're terminally ill and death is imminent
• Life-prolonging procedures declaration — instructions to provide maximum medical intervention regardless of prognosis
• Specific treatment preferences — detailed guidance on CPR, ventilators, feeding tubes, dialysis, antibiotics, and other interventions
• Organ donation instructions — authorizing or restricting anatomical gifts

A living will is one component within the broader advance directive. It addresses a specific scenario: what happens when you're diagnosed with a terminal, incurable condition and death is imminent. It does not cover situations where you're incapacitated but not terminal — a car accident that leaves you in a coma, for example, or a stroke that impairs your ability to communicate.

Why the Distinction Matters

If you only have a living will, you've documented your wishes for one specific scenario (terminal illness) but haven't named anyone to make decisions for you in other situations. Without a designated Healthcare Representative, Indiana's default consent hierarchy kicks in — your medical decisions fall to a court-appointed guardian, then your spouse, then a majority of your adult children, then your parents, and so on down the statutory list.

That hierarchy works on paper. In practice, it leads to delays, sibling disagreements, and situations where the hospital can't get consensus from multiple family members at the same priority level.

An advance directive with an HCR designation solves this. Your chosen representative has the legal authority to make all healthcare decisions — not just end-of-life ones — when your attending physician determines in writing that you cannot make or communicate decisions yourself and the HCR is available and willing to act.

One Current Witness Standard

For a current unified advance directive, use either a notary or two competent adult witnesses. If you use witnesses, your designated HCR cannot serve as a witness, and at least one witness must be unrelated to you by blood, marriage, or adoption. Use this one rule for the entire document, including living-will preferences.

Using a witness who does not meet the current requirements can put the directive's validity at risk; use the same witness rule for the entire document.

What About Old Documents?

If you executed a separate living will or healthcare power of attorney before January 1, 2023, those documents remain valid. But they may not reflect the broader authority that current law gives to Healthcare Representatives.

More importantly, if you signed a general durable power of attorney after December 31, 2022 that includes healthcare decision-making clauses, those healthcare clauses are void under current Indiana law. You need a separate, dedicated advance directive.

The practical recommendation: consolidate everything into a single current advance directive that covers your HCR designation, living will preferences, and specific treatment instructions in one document. The Indiana Advance Directive & Living Will Kit provides this unified template, fully compliant with SEA 204 standards, with witness eligibility guidance for the consolidated document.
