What this means in practice

Give copies to your doctor, your health care agent and close family, and keep the original where it can be found quickly. A living will that nobody can find cannot help.

Many states have rules about who may serve as a witness, for example excluding relatives or your health care providers. Check the statute before you sign.

Review the document after a major diagnosis, a move to another state or a change in your wishes.
