Power of Attorney (POA) is a legal document that grants someone the authority to act on your behalf in specific matters. This could include managing your financial affairs, making healthcare decisions, or handling legal matters, depending on the type of POA you choose. Establishing a POA is an essential part of planning for unexpected events like illness or incapacitation. If you're in Missouri and are wondering how to establish Power of Attorney, this guide will walk you through the process.



1. Understand the Different Types of Power of Attorney

Before establishing a POA, it's important to understand the different types that exist. Each type grants a different scope of authority:

  • Durable Power of Attorney for Healthcare: This document designates someone to make healthcare decisions on your behalf if you're unable to do so. It can include decisions about medical treatments, hospital admissions, and more.


  • Durable Power of Attorney for Finances: This gives someone the authority to manage your financial affairs, including paying bills, handling investments, or managing property.


  • Springing Power of Attorney: This type only becomes effective upon the occurrence of a specific event, such as the principal becoming incapacitated.


  • General Power of Attorney: This grants broad authority to the agent to act in almost any legal or financial capacity. However, it is typically only effective when the principal is mentally competent.


  • Limited Power of Attorney: This is used for specific tasks or transactions, such as selling property or managing a particular business transaction. It can be temporary or limited in scope.



2. Choose Your Agent Carefully

Your "agent" is the person you designate to act on your behalf. This individual must be someone you trust completely, as they will have significant authority to make decisions for you. An agent can be a family member, close friend, or legal professional, but they should be someone who understands your wishes and will act in your best interest.


If you choose a professional like a lawyer or financial advisor as your agent, make sure to discuss any fees or services they may charge in advance.



3. Complete the Power of Attorney Document

In Missouri, the POA document must be in writing and clearly outline the powers you are granting to your agent. While you can find generic POA forms online or in legal bookstores, it’s often wise to consult an attorney, especially if you’re dealing with complex financial or medical decisions.

The key elements to include in your POA document are:

  • Your full name and contact information: This confirms your identity as the principal.


  • Your agent’s name and contact information: Identify the individual or individuals you wish to serve as your agent(s).


  • Scope of authority: Clearly define what powers the agent will have, whether it’s for healthcare, finances, or legal matters.


  • Activation date: For a Springing POA, specify when the authority will become active (e.g., when you become incapacitated).



  • Revocation clause: Indicate if and when you can revoke or change the POA.

You can find specific forms for healthcare or financial powers of attorney through Missouri's official government websites or from a lawyer specializing in estate planning.



4. Sign the Document in Front of a Notary Public

In Missouri, a Power of Attorney must be signed by the principal in front of a notary public. Notarization ensures the authenticity of the document and helps prevent potential challenges to its validity later.


For healthcare powers of attorney, Missouri law also requires that the document be signed by two witnesses who are not named as the agent or their spouse. This is to ensure that the document is free from undue influence.



5. Distribute Copies of the Power of Attorney

Once the POA document is signed and notarized, distribute copies to relevant parties, such as your designated agent, family members, and any institutions where the POA may be used. For example, if your agent will be managing your finances, provide a copy to your bank or investment advisor. If it's a healthcare POA, give a copy to your primary care physician or hospital.


Make sure the agent knows where to find the original document, as they may need to present it to act on your behalf.



6. Store the Document Safely

Keep the original Power of Attorney document in a safe, secure location, such as a safe deposit box or fireproof file cabinet. Inform your agent of its location. Be sure that anyone you trust to help you during a medical or financial emergency knows where to find it.


It's also a good idea to keep a record of when and where the POA was signed, as well as the names of the notary and witnesses. This can help avoid any confusion or disputes later.



7. Revoking or Modifying Your Power of Attorney

If you decide to revoke or change your Power of Attorney at any time, you can do so by completing a revocation form. This document should clearly state that the previous POA is no longer valid. Be sure to notify your agent and any institutions or individuals who may have been relying on the original POA.


For changes to the POA, you can create a new document and follow the same process of signing and notarizing the new form. Be sure to provide updated copies to relevant parties.



8. Consider Legal Assistance

While creating a Power of Attorney is a relatively straightforward process, there are many nuances in how powers are granted and what decisions an agent can make. For complex situations, such as managing a large estate or making difficult healthcare decisions, it’s wise to consult an attorney who specializes in estate planning.


An attorney can ensure that your POA document complies with Missouri law and reflects your wishes. They can also guide you in choosing the right type of POA for your circumstances and offer advice on how to handle more complicated situations.



Final Thoughts

Establishing a Power of Attorney in Missouri is a proactive step in ensuring that your financial and healthcare needs are managed appropriately if you become unable to make decisions for yourself. By understanding the different types of POA, choosing a trusted agent, and properly executing the document, you can ensure that your wishes are respected and that someone is ready to step in on your behalf when needed.

Four people were injured in a crash on Keepsake Road in Camden County at approximately 12:48 p.m. on Sunday. The crash occurred as a Dodge SUV was traveling eastbound on Keepsake Road and hit a Chevrolet sedan head-on, according to a crash report from the Missouri State Highway Patrol. The 48-year-old man from Stoutland, who was driving the Dodge, was taken by ambulance to Mercy Hospital in Lebanon with serious injuries, according to the crash report. He was not wearing a seat belt, according to the report.  Three people in the Chevrolet sustained minor injuries and were taken to Lake Regional Hospital in Osage Beach by ambulance, according to the crash report. They were all wearing seat belts, according to the crash report. Head-on collisions are among the most dangerous types of car accidents, often resulting in life-altering injuries or fatalities due to the force of two vehicles colliding directly. These crashes frequently occur on rural roads or highways when a driver crosses the center line, drives the wrong way, or is distracted or impaired. The impact can cause severe trauma such as brain injuries, fractures, and internal damage, leaving victims facing long recoveries and significant financial burdens. Victims of crashes like these or other car accidents can call Daniel Finder at Finder Law, LLC for legal representation. All facts of the incident are based on preliminary reporting done by The Missouri State Highway Patrol & KOMU.

A 44-year-old Eldon man is seriously hurt after he crashed his UTV around 10:30 p.m. Wednesday in Miller County, according to a Missouri State Highway Patrol crash report. The report states the man was riding a 2015 Polaris Razor with a 17-year-old Eldon boy on Spring Garden Road, east of Short Road. He made a right turn, causing the UTV to flip onto its left side. The man was taken to Lake Regional Hospital by ambulance with serious injuries. The teen was taken to St. Mary's Hospital by ambulance with moderate injuries, according to the report. The report states they were wearing helmets at the time of the crash. The UTV had minor damage. UTV accidents are often far more serious than people realize, particularly when these recreational vehicles are struck by a full-sized car or truck. The limited protection UTVs offer—combined with their open design and lighter frame—can lead to catastrophic injuries, including broken bones, spinal trauma, and even fatalities. These incidents frequently happen when drivers of larger vehicles fail to see UTVs on rural roads or underestimate their vulnerability. Victims of crashes like these or other car accidents can call Daniel Finder at Finder Law, LLC for legal representation. All facts of the incident are based on preliminary reporting done by The Missouri State Highway Patrol & KMIZ.
