What Is a Power of Attorney and Why Do I Need One?
By Joshua Harden, Attorney | Memento Mori Law
A power of attorney can authorize someone you trust to act on specified matters when you need help.
Key Points at a Glance
Financial authority: An agent may be empowered to handle banking, property, or other transactions within the document's limits.
Durability matters: A durable power of attorney is generally designed to continue during incapacity, subject to state law.
Medical decisions may be separate: Health care directives and medical decision-making authority often require additional planning.
Choose carefully: Your agent should be trustworthy, capable, and willing to keep records.
It does not last forever: Authority generally ends at death, and other events may affect it.
Review the document: Make sure it grants the powers you intend and fits Kansas or Missouri requirements.
A Practical Example
Imagine you are temporarily hospitalized and cannot pay bills, handle a property closing, or speak with financial institutions. A properly prepared financial power of attorney may allow someone you selected to take appropriate action within the authority granted. Without that document, a family member may discover that being a spouse or adult child does not automatically give access to every account.
An agent has serious responsibilities. The agent should act within the document's authority and applicable law, keep good records, and avoid treating your money as their own. Choosing someone simply because they are the oldest child may not be the best choice if another person is better equipped to handle the work.
What to Review Before You Act
Think through the actual tasks you would want handled: banking, bills, real estate, taxes, benefits, or dealing with a business. Consider when the authority should begin, whether it should continue during incapacity, and who should serve if your first choice is unavailable.
Health care decisions are often addressed through separate documents. Kansas and Missouri have their own rules about the creation and operation of these instruments. A review can help avoid gaps between your financial authority, health care preferences, and any trust arrangements.

What Authority Can a Financial Agent Have?
A financial power of attorney may authorize a trusted person to handle banking, pay bills, manage real estate, deal with taxes, or complete other transactions specified in the document. The scope is not unlimited. A bank or other institution may need to review the document before accepting it.
Consider someone recovering from a serious accident. Even a temporary inability to sign paperwork can create problems with a mortgage payment or property closing. Planning ahead may allow an agent to address the situation without a court proceeding.
Durability, Timing, and Capacity
A durable power of attorney is generally intended to continue during the principal's incapacity, subject to the document and state law. Some instruments are effective when signed; others depend on specified conditions. The practical operation of a conditional document deserves careful review.
A person must have the legal capacity required to create a valid power of attorney. If a parent already has significant cognitive difficulties, relatives should not assume that a new form can simply be signed to solve the problem.
Choose an Agent Who Can Be Trusted
An agent may have access to sensitive information and substantial authority. Choose someone with good judgment, reliability, and a willingness to keep records. Consider an alternate and discuss the responsibilities in advance.
An agent generally owes duties to the principal and must act within the granted authority. Mixing funds, making gifts without authorization, or using the principal's money for personal purposes can create serious problems.
Health Care Authority Is Different
Financial authority does not necessarily allow an agent to make medical decisions. Health care directives and related documents should be considered separately. A person may choose different agents for financial and medical matters.
A living trust may also provide authority over trust assets, but it does not replace every function of a power of attorney. The documents should complement one another.
What Happens After Death?
A power of attorney generally ends at the principal's death. At that point a personal representative or trustee may have a role, depending on the assets and estate documents. An agent should not continue using authority that has ended.
Kansas and Missouri requirements and third-party practices differ. Joshua Harden can help prepare and review documents suited to the powers actually needed.
Kansas and Missouri: Legal Rules and Sources
Authority to Act During Life
Kansas: K.S.A. 58-652 sets out formal requirements for a durable financial power of attorney, including language establishing durability, signature, date, and acknowledgment requirements. A durable power can continue despite incapacity, but it does not give unlimited powers. Recorded powers and their revocation may raise additional recording requirements.
Missouri: RSMo 404.705 addresses the language and requirements for a durable power of attorney, while RSMo 404.710 addresses the scope of general powers and statutory limitations. An agent’s authority depends on the document and the law; some transactions need express authorization. Neither a financial power of attorney nor a medical directive should be assumed to cover every decision.
Court Protection and Alternatives
Kansas: The revised Chapter 59, Article 30 framework became effective January 1, 2026. K.S.A. 59-30,150 requires findings concerning less restrictive alternatives and a review hearing set 90 days after appointment; K.S.A. 59-30,211 contains transition rules for preexisting cases. The 2026 Kansas transition statute provides exceptions for existing proceedings, including provisions addressing when newly required plans apply. The existing appointment order and any subsequent court direction must be reviewed before assuming a deadline applies.
Missouri: RSMo 475.075 requires individualized consideration of incapacity, the respondent’s rights, and less restrictive alternatives. RSMo 475.080 addresses limited appointments. The Kansas 2026 deadlines and statutory scheme do not apply to Missouri proceedings. A power of attorney, trust, representative payee, or supported decision-making arrangement may address some needs without a full appointment.

Missouri Electronic Wills and Estate Documents: 2025 Law
Separately, RSMo 474.560 authorizes electronic execution of qualifying estate planning documents such as powers of attorney, trusts, beneficiary deeds, and health care directives, subject to other applicable legal requirements. Section 474.560 does not replace the special electronic-will rules. Kansas execution and recording requirements are separate and should not be assumed identical.
Missouri Electronic Execution and the Scope of an Agent’s Authority
Missouri RSMo 474.560, effective August 28, 2025, permits electronic execution of certain estate-planning documents, including qualifying powers of attorney and health care directives. Electronic form does not eliminate substantive requirements governing capacity, valid authorization, notarization or acknowledgment when applicable, or the agent’s legal duties. The Kansas execution and recognition rules must be considered separately. The document should be reviewed for the particular transaction and institution.
