An advance directive makes your medical treatment wishes clear if you're ever unable to speak for yourself because of illness, an accident, or advanced age. It combines two important documents: a living will and a health care power of attorney. Depending on your state, you might complete these forms separately or as one combined document. Either way, you must follow your state's specific rules for signing, witnessing, and notarizing to make sure your health care directives are legally valid.
After you complete a health care directive, follow these steps to make it legal:
Step 1. Sign your document in front of witnesses or a notary public. Wait until you are with them to sign. Your state may require you to sign in front of witnesses, a notary, or both.
Step 2. If your state requires it, have your agent sign the document. This is required in only a few states, including Alabama, Michigan, and Oregon. Check your state’s rules to be sure.
Step 3. If your state requires witnesses, have them sign after watching you sign. Most states require two witnesses to confirm that you appeared mentally competent and were not under pressure to sign. You can find your state’s witness rules at the end of this article, including who cannot be a witness. If your document also needs to be notarized, wait and go to the notary with your witnesses before signing.
Step 4. If needed, have your document notarized. Some states let you choose between witnesses or a notary, but several require both. The notary will watch you sign, check your ID, and add their official signature.
Step 5. Make copies and share them. Give copies to your health care agent, family, doctors, and any hospitals or care facilities where you receive treatment.
Step 6. Store the original in a safe place. Make sure your agent and family know where to find it if needed.
The rest of this article explains how to sign your advance directive and have it witnessed or notarized.
Every state requires your signature on an advance directive, or a signature by someone on your behalf if you can’t. Wait to sign your advance directive until you are with the required witnesses or notary. This step helps make sure someone independent can confirm you were mentally competent, of legal age, and acting freely when you made your directive.
Just a few states, including Alabama, Michigan, and Oregon, require your health care agent, and sometimes your alternate agent, to sign the document before they can act for you. If this applies in your state and you are using a state-approved form or a document from a lawyer, there should be a signature section for your agent.
If you are helping someone who is too ill or weak to sign their own health care documents, you or another person can sign for them if they ask you to. Most state forms have a section where you write the document maker’s name and your signature as the authorized signer.
If someone signs for another person, both people should be present together in front of the witnesses or notary. This lets an independent person confirm that the document maker asked for the signature and that it aligns with their wishes.
Your state’s rules say whether you need witnesses, a notary, or both to finish your advance directive. Some states allow either option, while others require both. You’ll find your state’s specific requirements below. Some states also have different rules for living wills and health care power of attorney documents.
Most states require two witnesses to observe your signing and provide written confirmation that you appeared mentally competent and were acting without coercion or undue influence.
States have rules about who can be a witness to avoid conflicts of interest. Usually, spouses, close relatives, people who might inherit from you, and your doctor cannot be witnesses. These rules make sure your witnesses have no personal or financial interest in your health care decisions. Your state’s witness restrictions are listed below and should also be on your forms above the witness signature lines.
A notary public is a state-authorized official who verifies signatures on legal documents. Finding a notary is usually easy. You can search online for local notaries, check with your bank, or ask at your hospital, where notary services are often available.
You can visit a notary’s office or have a mobile notary come to you. The notary will watch you sign, check your photo ID, and then sign the notary section on your form or attach a separate certificate. There is usually a small fee of about $10 to $20, with additional charges for mobile notaries. Some hospitals offer notary services free of charge.
Check the state requirements section below and your document’s instructions to see if notarization is required in your state and if there are any rules about who can notarize.
If your document needs both witnesses and a notary, it’s best for you and your witnesses to go to the notary together. Here’s how the process usually works:
Requirements can vary by state. Read the instructions that come with your advance directive to make sure you follow the rules. If you have questions, ask the notary, a patient representative at a health care facility, or an estate planning attorney.
Some states now allow remote finalization, especially remote notarization, but this is not common yet. Many states are still working out their rules and procedures.
If you can, it’s best to complete your documents in person. If you can’t travel to a notary, you might hire a mobile notary to come to you. As mentioned above, many hospitals also have a notary on staff who can help, sometimes for free. If you must use remote finalization, talk to a notary or attorney who knows your state’s remote witnessing and notarization laws to make sure you do it correctly.
If you can’t get the required signatures, still share your health care wishes with your loved ones and anyone who might make decisions for you. Even an unsigned directive can help guide them. While it may not be legally binding, it clearly shows your preferences.
