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.

A two-vehicle crash occurred on Wednesday evening on I-70 in Cooper County. At 5:48 pm, a Sedalia man driving a 2012 Nissan Frontier went off the roadway on Westbound I-70 in Cooper County to avoid the driver of a 2021 Westenstar 4700. The Nissan then went off the right side of the roadway and overturned. The driver of the 2021 Westenstar 4700 was taken to University Hospital by ambulance with minor injuries. Highway crashes are often especially dangerous because of higher speeds, heavier traffic, and limited reaction time, which can turn even a brief mistake into a serious collision. Victims frequently suffer traumatic brain injuries, spinal and neck injuries, broken bones, and internal injuries that may require extensive medical treatment and time away from work.

A staff member suffered minor injuries when a Montgomery County school bus was hit by a car Wednesday morning. The Montgomery County R-2 bus was hit at about 7:30 a.m. on Highway 19 near Route WW just north of New Florence, according to a Missouri State Highway Patrol crash report. A Hyundai Elantra driven by a 35-year-old Wellsville woman hit the bus after crossing the center line, the patrol reported. The Hyundai driver was taken by ambulance to Lake St. Louis Hospital with moderate injuries. The injured school employee, 63, of High Hill, was taken to the Hermann Area District Hospital with minor injuries. The one student on the bus was not hurt, said Superintendent Brian White. When a vehicle crosses the center line on a highway, the resulting crash is often violent due to high speeds and the risk of a head-on impact. These collisions frequently cause traumatic brain injuries, neck and spinal injuries, broken bones, internal organ damage, and severe soft-tissue injuries that can have lasting effects. In the most serious cases, victims are left facing long-term medical care, lost income, and permanent disabilities. If you or a loved one has been injured in a center-line crash, contact Daniel Finder at Finder Law, LLC to discuss your legal options and protect your right to full compensation.

A vehicle hit a pedestrian on a Cole County road Friday morning, closing it for an hour. Sgt. Kyle Green with the Missouri State Highway Patrol said troopers were investigating the pedestrian crash on Route Y near Helias Road just after 9 a.m. Green said the pedestrian was hurt, but he did not know the severity of those injuries. An ABC 17 News photographer on scene saw law enforcement and Cole County EMS. A photographer said first responders opened the road back up just after 10 a.m. A Missouri State Highway Patrol crash report says a 39-year-old Gravois Mills man was seriously injured in the crash and was brought to University Hospital by ambulance. The report says a 21-year-old Jefferson City man drove a 2008 Chevrolet Impala and failed to yield to a stationary vehicles stopped in the roadway. The man drove the Chevrolet across the center of the roadway and hit the pedestrian, the report says. An MSHP spokesman told ABC 17 News that the pedestrian was hit after they stepped off a trash truck. The Chevrolet had extensive damage and the driver had no reported injuries.

A rear-end accident along MO-52 left two men injured on Wednesday afternoon near Quarry Ln, prompting a response from area emergency services. According to the Missouri State Highway Patrol, the crash occurred at approximately 3:30 p.m. when a 2023 Ford Transit van, driven westbound by a 33-year-old man from Eldon, struck the rear of a 2001 Dodge Dakota that was stopped in the westbound lane. The impact caused significant damage to both vehicles, with the Dakota sustaining total damage. Both came to rest on the roadway facing westbound. The driver of the Dodge, a 72-year-old man from Versailles, was not wearing a seatbelt and sustained moderate injuries. He was transported by Mid-Mo Ambulance to Lake Regional Hospital for further treatment. The Ford driver initially refused care but was later listed with moderate injuries and taken to the same facility. Garbers Towing removed both vehicles from the scene as troopers with Troop F completed their investigation. The cause of the crash remains under review. Rear-end crashes may seem minor at first, but they often cause serious and lasting injuries. Victims commonly suffer whiplash, neck and back injuries, herniated discs, concussions, spinal injuries, and soft-tissue damage that can worsen over time. The sudden force of being struck from behind can also lead to chronic pain, limited mobility, and missed time from work, even when vehicle damage appears minimal. If you or a loved one was injured in a rear-end collision, call Daniel Finder at Finder Law, LLC to discuss your options and get experienced personal injury representation. All facts of the incident are based on preliminary reporting done by The Missouri State Highway Patrol.

Missouri State Highway Patrol troopers are investigating a crash that left one person dead involving two tractor trailers and one SUV, according to MSHP Troop F Sgt. Kyle Green. The crash happened between Centralia and Mexico on Missouri 22, near Audrain Road 215, according to an MSHP post. As of 9 a.m. Wednesday, the Missouri Department of Transportation planned to keep the highway closed for at least four more hours, according to Little Dixie Fire Protection District Chief Jason Henry. Emergency crews were first dispatched on reports of a semitruck on fire a few hours earlier that morning, Henry said. They were then paged again, but this time on reports of a second semitruck being rolled over and an SUV involved in the crash, according to the fire chief. Henry told KOMU 8 it appeared the SUV driver was ejected from the vehicle, adding the scene remains active. KOMU 8 was on the scene and saw one of the trucks involved was an Ameren vehicle. When a car is hit by a semi-truck, the sheer size and weight of the truck often lead to catastrophic injuries. Victims may suffer traumatic brain injuries, spinal cord damage, crushed or broken bones, internal organ injuries, severe burns, and permanent disabilities, even in crashes that happen at relatively low speeds. These collisions frequently result in long recovery periods, overwhelming medical bills, and time away from work, while trucking companies and insurers move quickly to protect themselves. If you or someone you love has been injured in a crash involving a semi, call Daniel Finder at Finder Law, LLC to protect your rights and pursue the personal injury compensation you deserve. All facts of the incident are based on preliminary reporting done by The Missouri State Highway Patrol and KOMU.
