How to Revoke an Advance Directive in Montana

How to Revoke an Advance Directive in Montana

Your advance directive is not permanent. Life changes — a new spouse, a different healthcare agent you trust more, updated treatment preferences after a diagnosis — and Montana law makes it straightforward to revoke or replace your directive at any time.

But "straightforward" does not mean "automatic." If you filed your directive with the Montana End-of-Life Registry, simply tearing up your paper copy is not enough. The registered version remains active and accessible to medical providers unless you take specific steps to remove or replace it.

How Revocation Works Under Montana Law

Under MCA 50-9-104, a Montana Living Will (Declaration) can be revoked at any time, in any manner, regardless of the declarant's mental or physical condition. That last part is significant — you can revoke your directive even if you are in a diminished mental state, which is not the case in all states.

Revocation can happen through:

• Verbal statement — telling your attending physician or healthcare agent that you revoke the directive
• Written revocation — signing a document that explicitly revokes the prior directive
• Physical destruction — tearing up, burning, or otherwise destroying the original document
• Executing a new directive — a later-dated advance directive automatically supersedes an earlier one

For a Living Will, the revocation takes effect immediately — as soon as you communicate it to your healthcare provider. No formal filing or waiting period is required.

Revoking a Healthcare Power of Attorney

A Durable Power of Attorney for Health Care follows a slightly different rule: the revocation does not take effect until your healthcare provider is actually notified. If you verbally tell your neighbor that you have revoked your healthcare agent's authority, but your physician's office still has the original on file, the original remains legally operative until someone informs the physician.

This means you should notify in writing:

1. Your current healthcare agent (the person you are removing)
2. Your attending physician or primary care provider
3. Any hospital or facility that has a copy on file

The Registry Step Most People Miss

If you registered your advance directive with the Montana End-of-Life Registry (maintained by the Department of Justice), revoking the paper document alone does not remove the registered digital copy. Medical teams accessing the registry in an emergency will still see your old directive and may follow its instructions.

To update or remove a registered directive:

1. Replacement: Execute a new, properly witnessed advance directive and submit it to the registry using the same Consumer Registration Agreement process. The new filing replaces the old one.
2. Removal: Contact the Montana Department of Justice, Office of Consumer Protection, and request removal of your registered directive. Send a signed, written request to: Department of Justice, Office of Consumer Protection, 2225 11th Avenue, PO Box 201410, Helena, MT 59620-1410.

Until the registry is updated, the outdated directive remains accessible. Given that registry processing takes approximately three weeks, act well before any scheduled medical procedure.

When to Revoke and Replace

Common situations that should trigger a review of your advance directive:

• Marriage, divorce, or the death of a spouse — especially if your spouse was your named healthcare agent
• Estrangement from your named agent — if you no longer trust the person to make decisions for you
• New medical diagnosis — a terminal diagnosis may change your preferences about life-sustaining treatment
• Relocation — if you moved to Montana from another state, your prior state's directive may not be accepted by Montana providers; execute a Montana-specific directive
• Change in values — your preferences about end-of-life care may evolve over time

As a general rule, review your advance directive every three to five years even if nothing dramatic has changed.

Partial Revocation

You do not have to revoke the entire document. If you want to change your healthcare agent but keep your treatment preferences, or update one section of your Living Will without altering the rest, execute a new directive that reflects your current wishes in full. The new, later-dated document supersedes the old one entirely.

Attempting to modify a directive by crossing out sections or adding handwritten notes is risky — it creates ambiguity that can lead to disputes or institutional rejection.

Protecting Against Unwanted Revocation

Some families worry about the opposite scenario: a confused or pressured patient revoking a carefully considered directive. Because Montana allows revocation "regardless of mental or physical condition," a patient in cognitive decline could theoretically revoke their directive.

If you are concerned about this, discuss it with your healthcare agent and physician in advance. A Mental Health Advance Directive — available under MCA Title 53, Chapter 21, Part 13 — allows you to include specific language about whether your directive should remain in effect during periods of diminished capacity.

The Montana Advance Directive & Living Will Kit includes both the standard advance directive forms and guidance on the mental health directive option, plus step-by-step instructions for registering with (and updating) the Montana End-of-Life Registry.
