Living Will in Washington State: Requirements, Forms, and How to Make Yours Valid

Most people assume a living will is a single, simple document. In Washington, it's more complicated than that — and getting it wrong means your wishes might be ignored in the exact moment they matter most.

Washington law calls its living will a Health Care Directive, governed by RCW 70.122. It only covers one narrow scenario: instructing physicians to withhold or withdraw life-sustaining treatment when you've been diagnosed with a terminal condition or permanent unconsciousness. For everything else — choosing a medical decision-maker, specifying treatment preferences during temporary incapacity — you need a separate Durable Power of Attorney for Health Care under RCW 11.125.

What a Washington Living Will Actually Does

A Health Care Directive activates only when two conditions are met simultaneously:

1. You lack decision-making capacity
2. An attending physician has diagnosed you with a terminal condition or two physicians confirm permanent unconsciousness

Until both triggers are present, the document sits dormant. It does not give anyone authority to make medical decisions for you during a recoverable illness, a temporary coma, or post-surgical confusion. That's what the DPOA-HC covers.

The directive lets you specify whether you want life-sustaining treatment withheld or withdrawn, including artificial nutrition and hydration. One critical exception: if you're pregnant and your physician knows about it, the directive has no legal effect during the pregnancy under RCW 70.122.030 — regardless of what you wrote.

Signing and Witness Requirements

Washington gives you two options for making your living will legally valid:

Option A — Notary acknowledgment. A notary public witnesses your signature. No additional witnesses needed. This is the cleanest route.

Option B — Two independent witnesses. Both witnesses must be competent adults who watch you sign. But the eligibility rules are strict. A witness cannot be:

• Related to you by blood, marriage, or registered domestic partnership
• Named as your healthcare agent
• Your attending physician or their employee
• An employee of the health facility where you're currently a patient
• Anyone with a claim against your estate after death

The notary and witness routes are mutually exclusive — you don't need both. If you're unsure whether your chosen witnesses qualify, the notary route eliminates all ambiguity.

How to Make a Living Will in Washington: Step by Step

1. Decide what you want. Think through specific scenarios: terminal cancer with no treatment options, permanent vegetative state, late-stage organ failure. For each, decide whether you want all available treatment, comfort care only, or something specific.

2. Document your instructions. Use a Washington-specific form that references RCW 70.122. Generic templates from national websites often miss state-specific requirements like the pregnancy exclusion and witness disqualifications.

3. Execute the document properly. Sign, date, and have it witnessed (notary or two qualified witnesses). A single witness who turns out to be disqualified can void the entire document.

4. Distribute copies. Give copies to your primary care physician, your designated healthcare agent, your local hospital's admitting department, and at least one trusted family member. Washington's Health Care Declarations Registry under RCW 70.122.130 has been administratively suspended due to lack of funding, so you cannot rely on a state registry for storage.

5. Pair it with a DPOA-HC. A living will alone leaves major gaps. Without a designated agent, medical decisions during non-terminal incapacity fall to Washington's default surrogate hierarchy under RCW 7.70.065 — and if you have multiple adult children, they must reach unanimous agreement before any treatment decision moves forward.

Common Mistakes That Invalidate Washington Living Wills

Using an out-of-state form. Washington will honor directives executed in other states, but only to the extent they comply with Washington law. A form missing the required witness disclosures or using different activation criteria may be challenged.

Storing the original in a safe deposit box. Banks close on weekends and holidays. If you're rushed to the hospital on a Saturday night, no one can access your directive.

Forgetting to update after divorce. Under RCW 11.125.085, divorce automatically revokes a former spouse's authority as your healthcare agent. But it doesn't automatically update your living will's instructions. Review and re-execute both documents after any major life change.

Assuming your spouse automatically decides. Washington is a community property state, but community property rules govern assets — not medical decisions. Without a DPOA-HC, your spouse still has to navigate the statutory priority list alongside any other family members who show up at the hospital.

Why a Living Will Alone Isn't Enough

The living will handles a narrow set of end-of-life scenarios. But most medical crises don't start as terminal diagnoses. A stroke, a car accident, a surgical complication — these situations require someone to make real-time treatment decisions while doctors are still working to save you. That's the DPOA-HC's job.

Washington's advance directive kit integrates both documents — the Health Care Directive and the DPOA-HC — along with a body disposition directive, witness validation checklist, and POLST preparation guide. Having everything in one coordinated system prevents the gaps that leave families scrambling during a crisis.
