A power of attorney can only be signed by someone who still has the capacity to understand it. Once that window closes, it closes for good. The family is left with the court.
That is the situation behind most calls we get about guardianship in Missouri. A parent is no longer safe managing money or medical decisions, nothing was ever signed, and the bank has stopped accepting a daughter’s word for it.
Missouri Splits the Job in Two
Many states use one word for this. Missouri uses two, and the distinction matters when a petition is filed.
- A guardian handles the person: medical care, where someone lives, daily support. The person under a guardianship is called a ward.
- A conservator handles the money and property. That person is called a protectee.
One person often serves in both roles, though a court can divide them, with one sibling managing care and another managing finances. These cases are heard in the probate division of the circuit court, the same division that handles probate and estate administration.
What the Court Has to Find
Nobody loses the right to make decisions because a relative is worried. Missouri requires clear and convincing evidence that the person is incapacitated or disabled as the statute defines those terms, and the court may order a medical examination.
The law favors the least restrictive option available. If someone can still handle part of their own affairs, a court can order a limited guardianship that removes only specific rights and leaves the rest intact.
Your Parent Gets Their Own Attorney
This surprises families more than anything else in the process. When a petition is filed, Missouri law requires the court to immediately appoint an attorney for the person named in it. That attorney must visit before the hearing, and the person filing the petition is not permitted to choose who it is.
The respondent also has the right to attend, present evidence, cross-examine witnesses, and request a jury trial. The proceeding is adversarial by design, which is appropriate given what is at stake, and it is why these cases feel harder than relatives anticipate.
Who the Court Appoints
Missouri sets an order of priority. If the person can still communicate a reasonable choice at the hearing, their own nomination comes first. Beyond that, the court follows the most recent valid nomination the person made in a durable power of attorney or signed writing, absent good cause to depart from it.
A court will not appoint an unrelated third party unless no suitable relative is willing to serve. Where siblings disagree about a parent’s care, that disagreement tends to surface here, in front of a judge.
What Would Have Prevented This
A financial power of attorney and a health care power of attorney, signed while capacity remains, let a trusted person step in without a courtroom. They cost a fraction of a contested proceeding.
Missouri also lets a person name a preferred guardian in advance, and the court is directed to honor that nomination in most circumstances. A document signed today can decide who stands in that role years from now, which is reason enough to revisit estate planning in Des Peres before anything goes wrong.
Key Takeaways
- Missouri appoints a guardian for personal decisions and a conservator for finances.
- The court must find incapacity by clear and convincing evidence, supported by medical proof.
- Limited guardianships exist so a person keeps whatever rights they can still exercise.
- An attorney is appointed for the parent, who may also request a jury trial.
- Relatives have priority, and a person’s own advance nomination usually controls.
- Powers of attorney signed while capacity remains avoid the proceeding entirely.
If You Are Already Past That Point
Plenty of families find this page after the window has closed. That is workable. Guardianship exists because capacity sometimes disappears before the paperwork gets done, and a well-prepared petition moves more smoothly than one assembled in a hurry.
