Kansas family reviewing living will and healthcare power of attorney documents with an attorney

Living Will vs Healthcare Power of Attorney in Kansas: Why You Need Both

August 20, 2026•6 min read

People often use the terms living will and healthcare power of attorney as if they mean the same thing. They do not. They are two different documents that do two different jobs, and in Kansas most families need both. Understanding the difference matters, because a gap between them is exactly where families end up guessing at a hospital bedside about what a loved one would have wanted, without the legal authority to act on it.

What a Living Will Does

A living will is a written statement of your wishes about life sustaining treatment if you are terminally ill or permanently unconscious and cannot speak for yourself. In Kansas it is sometimes called a declaration relating to life sustaining procedures. It speaks for you in a very specific situation: when your condition is terminal and the only question is whether certain treatments should be used to prolong the dying process.

A living will, answers questions about your wishes directly. Do you want to be kept on artificial life support if there is no reasonable hope of recovery? Do you want or decline artificially supplied nutrition and hydration? It puts those decisions in writing, ahead of time, so your family and your doctors are not left to guess and so no one has to carry the weight of that choice without knowing what you wanted.

What it does not do is cover the countless other medical decisions that come up when someone is incapacitated but not terminally ill. That is the gap the second document fills.

What a Healthcare Power of Attorney Does

A Healthcare Power of Attorney is a document in which you name a person, called your Agent, to make medical decisions on your behalf when you cannot make them yourself. Unlike a living will, it is not limited to end of life situations. It applies any time you are unable to communicate or make your own healthcare decisions, whether that is temporary, such as during surgery or a serious illness, or permanent.

A healthcare power of attorney applies to a much broader range of medical decisions than a living will, which speaks only to the limited end of life circumstances it addresses. A stroke, a bad car accident, advanced dementia, or a period of unconsciousness can all leave a person unable to make decisions without being terminally ill. In those moments, someone has to decide which treatment to pursue, which facility to use, or which specialist to consult. A Healthcare Power of Attorney gives a person you trust the legal authority to make those calls, guided by their knowledge of your values.

Why One Without the Other Leaves a Gap

Here is the problem with having only one. A living will lets you speak directly to your physician through the document itself, instructing the physician to withhold or withdraw life prolonging procedures in the limited circumstances the living will addresses. It says nothing about the wide range of medical decisions that arise in a non terminal crisis, and it names no one to act for you. A Healthcare Power of Attorney lets you speak instead through a person you choose. Your Agent can address medical decisions well beyond the narrow end of life circumstances a living will covers, but without a living will there is no document in which you have spoken directly to your physician about life prolonging treatment.

Together, they cover both dimensions. The living will, records your own directions to your physician about life prolonging procedures in a terminal or permanently unconscious condition. The Healthcare Power of Attorney names a trusted person to make the many other medical decisions no document can anticipate. One speaks directly to the doctor. The other provides a decision maker. Most Kansas families need both working in tandem, which is why we treat them as a pair rather than an either or choice.

Because your Agent may also have authority concerning end of life care, the two documents can sometimes appear to conflict. A living will may direct the physician to withhold life prolonging procedures, while the Agent asks for a short delay so a family member who is traveling can arrive, or so a second medical opinion can be obtained.

Which direction controls in that moment, and whether the two documents can be reconciled, depends on how the documents were drafted and on how Kansas law applies to the situation in front of the doctors. That is not a question to leave to a form. Careful construction of both documents, with experienced counsel, is what keeps your Agent and your physician working from the same instructions. If you are not sure how your current documents would interact, talk with an experienced elder law or estate planning attorney before a crisis makes the question urgent.

How These Fit With the Rest of Your Plan

Healthcare documents are only one part of planning for incapacity. They handle medical decisions, but they do nothing about the rest of your affairs. That job belongs to a general Power of Attorney. It is commonly called a financial power of attorney, and it does cover money matters such as paying bills, managing accounts, and handling property, but its reach goes beyond finances. A general Power of Attorney can also authorize someone to deal with government agencies such as Social Security, Medicare, and KanCare, sign leases and contracts, handle insurance and vehicle matters, request records, and manage mail, tax filings, and digital accounts. Trust based planning can accomplish many of the same asset management goals, because a trustee can hold and manage whatever the trust owns, but a general Power of Attorney is still necessary for the non healthcare matters that fall outside the trustee's authority, such as dealing with government agencies or handling assets that were never transferred to the trust. We have written separately about why a basic financial Power of Attorney form often is not enough to protect a family in a real crisis (link to /post/power-of-attorney-kansas-elder-law).

Putting all of these in place while you are healthy and able to make your own decisions is the point. Once a person has lost the capacity to understand and sign these documents, the opportunity is gone, and the family's only remaining option may be a court supervised guardianship and conservatorship. Healthcare directives exist precisely so your family never has to go to court to gain the authority to help you.
