Can Family Members Override Advance Directives?

Families often ask whether a spouse or an adult child can step in and change course when a loved one's living will says one thing and the family wants another. In Washington, the short answer is reassuring: a valid advance directive is meant to be followed, not overruled by relatives who disagree.

A Valid Directive Speaks With Your Authority, Not Your Family's

Washington's advance directive is created under the Natural Death Act, chapter 70.122 RCW. The entire point of the law is to let you make binding decisions about end-of-life care before you lose the ability to communicate them. The statutory directive form in RCW 70.122.030 puts this in plain language: it states that the directive shall be honored by your family and physicians as the final expression of your legal right to refuse medical or surgical treatment, and that you accept the consequences of that refusal.

Read that again, because it is the crux of the matter. The directive is described as your final expression, and it says your family is to honor it. That framing is deliberate. When you sign a valid directive, you are exercising a legal right that belongs to you, and your relatives do not have the authority to cancel your choice simply because they would have decided differently.

What Makes a Directive Valid in the First Place

Because so much rides on validity, it is worth knowing what the law requires. Under RCW 70.122.030, a directive must be signed by you as the declarer and either acknowledged before a notary or signed in the presence of two qualifying witnesses. Those witnesses cannot be related to you by blood or marriage, cannot be people who would inherit from your estate, and cannot be your attending physician or an employee of that physician or of the facility where you are a patient. These rules exist precisely to guard against pressure and conflicts of interest, so that the document truly reflects your wishes.

There is also a medical trigger. Before life-sustaining treatment is withheld or withdrawn based on your directive, your terminal condition must be diagnosed in writing by your attending physician, or your permanent unconscious condition must be confirmed by two physicians, and that finding must be entered into your medical record. In other words, a directive does not switch off care on a family member's say-so. It operates only when the medical criteria you specified are actually met and documented.

Where the Confusion Comes From: The Surrogate Hierarchy

Much of the worry about families "overriding" a directive comes from a misunderstanding of a separate statute, RCW 7.70.065. That law creates a priority list of people who can give informed consent to health care for a patient who lacks capacity: first any court-appointed guardian, then a person holding a durable power of attorney for health care, then a spouse or state registered domestic partner, then adult children, then parents, then adult siblings, and on down the line.

At first glance, that list can look like it hands your relatives power over your care. But it does the opposite of overriding your directive. The surrogate hierarchy is a fallback that applies when there is no directive and no health care agent already speaking for you. It fills a gap; it does not fill a role you have already filled. If you have signed a valid directive stating your wishes about life-sustaining treatment, that directive already answers the question the surrogate list exists to answer. A family member consenting under RCW 7.70.065 is supposed to be carrying out your known wishes, not substituting their own.

The statute reinforces this. It directs that a surrogate must first determine, in good faith, what you would have chosen if you could decide for yourself, and only then, if that cannot be determined, may they act in your best interests. A directive is the clearest possible evidence of what you would choose. It guides the surrogate rather than being erased by one.

What Happens When Relatives Disagree Anyway

In the real world, a grieving family member may still object, and a hospital may pause while everyone sorts things out. That friction is exactly why a properly drafted, properly witnessed directive matters so much. When your wishes are documented and legally valid, your physicians have both the authority and the protection to follow them, and your family has far less room to relitigate the decision at the bedside. The directive does not just express your wishes; it settles the question.

You can strengthen this further by naming a health care agent through a durable power of attorney, so that a single trusted person has clear authority and there is no scramble down the priority list. When your chosen agent and your written directive point the same direction, disagreement among other relatives has very little traction.

A Snohomish County Perspective

For families in Snohomish County, these questions rarely arrive at a convenient time. They surface in an ICU in Everett or during a sudden decline at a care facility in Edmonds, when emotions are high and time is short. Planning ahead is what keeps a family together instead of divided. A directive that clearly states your wishes, paired with a health care power of attorney naming someone you trust, means your loved ones can support one another rather than argue over what you would have wanted.
