Indiana Advance Directive Witness Requirements: Who Can and Cannot Sign

Picking the wrong witnesses is the single most common reason Indiana advance directives get challenged. The rules are not intuitive — a family member who seems like a natural choice may be ineligible, so screen witnesses before signing.

Understanding these rules before you sit down to sign saves you from discovering the problem in a hospital when it is too late to fix.

Two Paths to Validation

Indiana gives you two options for validating your advance directive signature:

Option A: Notary public. One notary witnesses your signature. No additional witnesses required. This is the simpler path and avoids the complex witness eligibility rules entirely.

Option B: Two adult witnesses. Both witnesses must be present when you sign (in person, via live video, or via telephone as a last resort). Both must be competent adults. This option triggers the eligibility restrictions below.

Witness Rules for a Current Advance Directive

For a current Indiana advance directive, the witness requirements are:

• Your appointed HCR cannot serve as a witness
• If someone else signs your name at your direction, that person cannot be a witness
• At least one of the two witnesses must be unrelated to you by blood, marriage, or adoption

This means one family member can witness, but the second must be someone outside your family — a neighbor, coworker, friend, or other unrelated adult.

Applying the Rule to Living-Will Preferences

An advance directive can record living-will preferences. Use the same witness rule for the entire document: either a notary or two competent adult witnesses; if using witnesses, the named HCR cannot witness and at least one witness must be unrelated. Older, separate living-will declarations may have additional statutory requirements, so do not mix older forms with a current unified directive without checking how they were executed.

Can a Family Member Witness?

Under the current rule:

A family member who is not the HCR: Yes — one family member can witness as long as the other witness is unrelated, and neither is the appointed HCR.

The document includes living-will preferences: The same rule applies; family members are not automatically disqualified, but the HCR cannot witness and at least one witness must be unrelated.

This catches people off guard. A spouse and adult child can be used only if neither is the HCR and at least one is unrelated to the patient by blood, marriage, or adoption.

Remote Witnessing Under SEA 204

Indiana permits remote execution via live audio-visual call. Witnesses do not need to be physically present in the same room — they can observe your signing over a video conference. If signing paper counterparts during the video call, all separately signed pages must be compiled into a single composite document within 10 business days.

As a last resort, telephonic witnessing is permitted when video is impossible. Under this exception, the witnesses must establish your capacity and identity over the phone, and the final document must state that telephonic interaction was used.

What Happens If Witnesses Are Invalid

If your witnesses do not meet the current requirements, the directive's validity can be challenged or the document may not be accepted when needed, and your medical decisions may default to Indiana's statutory consent hierarchy.

Getting witness selection right is essential. The Indiana Advance Directive & Living Will Kit includes a built-in witness eligibility checklist for the current rule.
