Living will requirements in Kansas

Kansas calls its living will the Declaration, made under the state's Natural Death Act, and keeps it separate from the Durable Power of Attorney for Health Care Decisions, the document that names your agent. You must be an adult, 18 or older, to sign either one, and both are valid the same way: signed before two witnesses, or instead acknowledged before a notary public. Kansas sets the Declaration aside for the rest of a pregnancy.

Which document is this, really

Kansas’s living will has a specific statutory name: the Declaration, made under the state’s Natural Death Act. It is a written statement of the treatment you do and do not want if you are ever in a terminal condition and cannot speak for yourself. Naming someone to decide on your behalf is a separate job, done in a separate document, the Durable Power of Attorney for Health Care Decisions. The person you name in it is your agent.

The two are not one form split into two sections; they are two acts, each with its own execution section and its own printed form. The Natural Death Act sits in chapter 65 of the Kansas statutes; the Durable Power of Attorney for Health Care Decisions sits in chapter 58, inside Kansas’s general power-of-attorney article. Both statutes print a form and say it should be followed in substantially that wording, which leaves room for your own phrasing as long as the substance matches. Kansas does not treat either printed form as strictly mandatory word for word.

This is the pairing Myend’s Healthcare Directive prepares for Kansas: a Declaration for your wishes, and a Durable Power of Attorney for Health Care Decisions for your agent, each formatted the way Kansas expects.

Who can make a Kansas advance directive

The Natural Death Act says “any adult person” may sign a Declaration, without printing a number. Kansas’s general age of majority statute supplies the number: eighteen. The Durable Power of Attorney for Health Care Decisions does not set an age of its own for the person granting it either; it borrows the same statewide age of majority. So for either document, the floor is the same: you need to be 18 to sign it yourself.

Age is the state’s rule; understanding what you are signing is the practical test underneath it. Signing either document means you understand, at that moment, what it says, what it changes, and, for the Durable Power of Attorney, what it means to hand someone else the authority to decide for you. Nobody has to certify that understanding in advance. If a question about it ever comes up later, it comes up because someone raises it, not because you needed a form filled out first.

Signing it so it counts

Kansas gives both documents the same choice on how to sign, but each one screens its witnesses against a different list. Do not swap them: a witness who is fine for the Declaration is not automatically fine for the Durable Power of Attorney, because the two lists are worded differently.

The Declaration

  1. You sign

    You sign the Declaration, or direct someone to sign it for you and at your direction.

  2. Two witnesses, or a notary

    Sign in front of two witnesses at least 18 years old, or skip the witnesses entirely and have your signature acknowledged before a notary public instead. Either route on its own makes the Declaration valid.

  3. If you use witnesses

    Neither witness may be: the person who signed the Declaration on your behalf and at your direction, someone related to you by blood or marriage, someone entitled to any part of your estate under Kansas intestacy law or under your will or a codicil to it, or anyone directly financially responsible for your medical care.

If you choose the notary route instead, the witness lines are replaced by a notary acknowledgment block, and no witnesses are needed at all.

The Durable Power of Attorney for Health Care Decisions

Naming your agent is a separate signing, on its own paper, and Kansas gives it the same either/or choice: dated and signed in the presence of two witnesses at least 18 years old, or acknowledged before a notary public instead. The witness list here is its own, not borrowed from the Declaration: neither witness may be your agent, someone related to you by blood, marriage or adoption, someone entitled to any part of your estate under intestacy or under your will or a codicil to it, or anyone directly financially responsible for your health care.

Naming your agent

Your Durable Power of Attorney for Health Care Decisions is where you name your agent, the person authorized to make health care decisions for you. Kansas disqualifies only a narrow group from actually holding that role: your treating health care provider, an employee of that provider, or an employee, owner, director or officer of the facility treating you. Even that disqualification has a built-in exception. It does not apply if the person is related to you by blood, marriage or adoption, or if you and that person belong to the same community of persons bound by vows to a religious life. Outside those categories, anyone you trust can serve.

Kansas fences the role in one direction that matters if you sign both papers. Your agent’s powers reach only as far as what you set out in writing, and they can never include revoking or invalidating a Declaration you made under the Natural Death Act. Your living will is not something your agent can undo.

When it takes effect

Your Declaration takes effect once two physicians, your attending physician plus one other, personally examine you and certify in writing that you are in a terminal condition. Until that written certification exists, the Declaration has no operative force.

The Durable Power of Attorney for Health Care Decisions runs on a different trigger, written into its own statute. No power you grant your agent takes effect until your impairment occurs, as determined by your attending physician, unless the document you sign specifically provides otherwise. Kansas’s printed form makes that choice visible: it carries an effective-time line where you say whether the power starts immediately or only upon your disability or incapacity. So the two-physician terminal certification belongs to the Declaration alone, and your agent’s authority turns on the narrower question of whether you are impaired.

If you are pregnant

If your attending physician diagnoses you as pregnant, Kansas law sets your Declaration aside for the rest of the pregnancy. The rule carries no conditions: it does not ask how far along the pregnancy is, and it does not require a second physician’s opinion the way some other states do. It sits at the end of the same subsection that lays out the Declaration’s witness-or-notary signing choice, rather than in a subsection of its own.

This rule belongs to the Declaration. Kansas law does not carry a separate pregnancy clause for the Durable Power of Attorney for Health Care Decisions.

Changing or cancelling it

You can revoke your Declaration at any time, in any of three ways: physically destroying, obliterating or defacing it with the intent to cancel it, signing and dating a written revocation, or telling someone orally that you revoke it, in front of a witness 18 or older who then signs and dates a writing confirming that you said it. A spoken revocation takes effect once your attending physician receives that writing, and the physician records the time, date and place of the notice in your medical record. Nobody is liable for failing to honor a revocation they did not actually know about.

The Durable Power of Attorney for Health Care Decisions handles this inside the document itself. Kansas’s printed form carries its own revocation paragraph, which says the power is revoked by an instrument in writing executed, witnessed or acknowledged in the same manner as the original, and which invites you to set out a different manner of revocation if you would rather. The same form opens by revoking any durable power of attorney for health care decisions you made before it. Here too, a good-faith agent who acts without actual knowledge of a revocation is not held to it.

Making sure it is found

A Declaration or a Durable Power of Attorney nobody can find works no better than having none at all. Give a copy of each to your agent, your physician, and the hospital you are most likely to use, and keep the signed originals somewhere your family knows to look. Carrying a card that names the documents and says where they are kept closes most of the gap that a hospital’s own filing system will not.

If you are ever treated somewhere other than Kansas, or move here after signing in another state, do not assume the answer either way. Check the rule of the state where you are being treated before you rely on a document signed under a different state’s law.

This is not a POLST

Your Declaration and your Durable Power of Attorney for Health Care Decisions are documents you complete now, for a future you cannot yet see. A portable medical order works differently: a clinician fills it out together with you once you are already facing a serious illness, as a set of specific medical orders meant to travel with you between hospital, nursing facility, home and ambulance. Myend prepares the Declaration and the Durable Power of Attorney. It does not, and cannot, produce a portable medical order, because that has to come from whoever is treating you.

What is different about Kansas

Kansas hands you two documents, then gives both of them the same choice: two witnesses, or a notary.

Kansas is a two-document state, but unlike some of its neighbors it does not split the signing rule between the two. Both the Declaration and the Durable Power of Attorney for Health Care Decisions accept two witnesses or a notary, on equal footing. What does not carry over is who is allowed to witness which document. The Declaration’s disqualified-witness list is built around your estate and your medical care; the Durable Power of Attorney’s list is built around your agent and your health care, worded separately in a different chapter of the statutes entirely.

The pregnancy rule is unconditional and it is written into the same sentence that closes out the Declaration’s signing subsection, not set apart in a subsection of its own. It applies only to the Declaration. Kansas’s power-of-attorney statute has no matching clause, and it switches your agent’s authority on at a different moment: your impairment, as your attending physician determines it, rather than the Declaration’s two-physician terminal certification.

None of that makes Kansas a hard state to plan in. It is a state that keeps your wishes and your choice of agent on two separate pieces of paper, gives you the same easy signing choice on both, and simply expects you to read each one on its own terms rather than assuming one document’s rule fits the other.

Common questions

Does the Declaration have to be notarized in Kansas?
No, not unless you choose that route. Kansas lets you sign the Declaration before two witnesses, or skip the witnesses entirely and have your signature acknowledged before a notary public instead. Either one makes it valid on its own. The Durable Power of Attorney for Health Care Decisions gives you the exact same choice, on its own paper.
What is the difference between the Declaration and the Durable Power of Attorney for Health Care Decisions?
The Declaration, made under Kansas’s Natural Death Act, carries your own instructions about withholding or withdrawing life-sustaining procedures if you are ever in a terminal condition. The Durable Power of Attorney for Health Care Decisions is a separate document that names your agent, the person who can make health care decisions for you. Kansas treats them as two acts with two execution sections and two forms, not one combined paper.
How many witnesses does Kansas ask for, and who cannot be one?
Two, for either document, unless you choose the notary route instead. For the Declaration, your witnesses cannot be the person who signed on your behalf and at your direction, anyone related to you by blood or marriage, anyone who would inherit any part of your estate under Kansas intestacy law or under your will, or anyone directly financially responsible for your medical care. The Durable Power of Attorney draws its own, separate list: not your agent, not a relative by blood, marriage or adoption, not an heir under intestacy or your will, and not anyone directly financially responsible for your health care.
Who can be my agent in Kansas, and what can they decide?
Almost anyone you trust, once you are an adult naming them in your Durable Power of Attorney for Health Care Decisions. Kansas disqualifies only your treating health care provider, an employee of that provider, or an employee, owner, director or officer of the facility treating you, and even that disqualification lifts if the person is related to you by blood, marriage or adoption, or belongs to the same vowed religious community as you.
Is this the same as a POLST-type medical order in Kansas?
No. Your Declaration and your Durable Power of Attorney are documents you complete now, for a future you cannot yet see. A portable medical order is different: a clinician fills it out together with you once you are already seriously ill, as a set of specific instructions meant to travel with you between hospital, nursing facility and home. Myend prepares the Declaration and the Durable Power of Attorney. It does not produce a portable medical order, because that has to come from whoever is treating you.
Do I need a lawyer to make a Kansas advance directive?
No. Kansas does not require an attorney for the Declaration or for the Durable Power of Attorney for Health Care Decisions. Both statutes print a form you can use as written, in substantially the same wording, without hiring anyone.
Can I change or cancel my Kansas directive?
Yes, and each document is cancelled its own way. You can revoke your Declaration by destroying or defacing it, by signing and dating a written revocation, or by saying out loud that you revoke it in front of a witness 18 or older who then signs and dates a writing confirming you said it; a spoken revocation takes effect when your attending physician receives that writing and notes the time, date and place in your record. The Durable Power of Attorney is handled by the printed form, which says it is revoked by a writing executed, witnessed or acknowledged the same way the original was, unless you wrote a different method into the document yourself. Neither revocation reaches back to hold anyone liable who acted in good faith without knowing about it.
When does my Kansas Declaration actually take effect?
Once two physicians, your attending physician plus one other, personally examine you and certify in writing that you are in a terminal condition. Your Durable Power of Attorney runs on a different clock: unless the document says otherwise, your agent’s powers take effect when your impairment occurs, as determined by your attending physician, with no second opinion and no terminal diagnosis needed.
