Advance directives are governed by state law — and the rules vary significantly from state to state. Understanding your state's specific requirements is essential to ensuring your documents are legally valid when they're needed.
Why State Laws Matter
A document that meets every requirement in one state may be technically invalid in another. While most states have provisions for recognizing out-of-state advance directives, these provisions don't always apply uniformly — and in a medical emergency, you don't want there to be any question about whether your document is valid.
Key Requirements That Vary by State
Witnessing Requirements
Most states require advance directives to be signed in the presence of two adult witnesses who also sign the document. However, states differ on who cannot serve as a witness. Common exclusions include:
- Your designated healthcare agent/proxy
- Relatives by blood, marriage, or adoption
- Anyone who stands to inherit from your estate
- Your treating physician or their employees
- Employees of the healthcare facility where you're being treated
Notarization Requirements
Some states require advance directives to be notarized in addition to or instead of witnessed. Requirements for both notarization and witnessing exist in some states; others require only one or the other. Using your state's official form is the simplest way to ensure you meet local requirements.
Official State Forms
Most states provide official, state-specific advance directive forms through their Department of Health or Office of the Attorney General. Using these forms ensures you meet your state's formatting and content requirements. Many also include helpful prompts and explanations.
Living Will vs. Combined Form
Some states have separate forms for a living will and a healthcare proxy; others combine them into a single document. A few states use a single comprehensive advance directive form that addresses both healthcare preferences and agent designation.
What Happens If You Move?
If you move to a new state, your existing advance directive may still be valid — most states have "reciprocity" provisions recognizing out-of-state documents if they were valid when and where executed. However, to avoid any ambiguity, the safest course is to complete new documents using your new state's forms after moving.
Multi-State Considerations for Frequent Travelers
If you spend significant time in multiple states — seasonal residents, frequent travelers, "snowbirds" — consider completing advance directive forms for each state where you regularly receive healthcare. Keep copies accessible in each location.
The Five Wishes Document
The Five Wishes document is a nationally recognized advance directive written in plain language. It is legally valid in 47 states (with some additional steps needed in the other three) and covers both healthcare preferences and agent designation in a single, comprehensive document. It's available through Aging with Dignity at agingwithdignity.org.
Keeping Documents Current and Accessible
Once completed, your advance directives are only useful if the right people have access to them. See our guide to storing and sharing legal documents for best practices. For the full overview of advance directive types and how to complete them, see our complete guide to advance directives.
