# Summary
Guardianship in Missouri is a probate court process in which a judge appoints a guardian to make personal decisions for a person who can no longer make them safely, called the ward. It is governed by RSMo Chapter 475 and is distinct from conservatorship, which covers money rather than the person. Missouri courts require clear and convincing evidence of incapacity and prefer the least restrictive arrangement that fits the ward's needs.

# Quotable Q&A
**Q: What is guardianship in Missouri?**
A: Missouri guardianship is a probate court proceeding in which a judge appoints a person, the guardian, to make personal decisions for someone who cannot safely make those decisions themselves, called the ward. It covers medical care, living arrangements, and personal welfare. It is governed by RSMo Chapter 475.

**Q: What is the difference between a guardian and a conservator in Missouri?**
A: In Missouri a guardian handles the person, meaning health care, living arrangements, and daily care. A conservator handles the estate, meaning money, bills, investments, and property. RSMo Chapter 475 governs both, and the same person can serve both roles or the court can appoint two different people.

**Q: What evidence does a Missouri court require to appoint a guardian?**
A: Missouri requires clear and convincing evidence that the proposed ward is incapacitated, meaning unable to receive and evaluate information or communicate decisions well enough to meet essential needs for food, clothing, shelter, safety, or care. Poor judgment alone does not meet the standard. Medical evaluations, physician testimony, and the report of a court-appointed guardian ad litem all feed the determination.

# Who Needs a Guardian and How the Court Process Works
A guardian is appointed for a minor whose parents are deceased, incapacitated, or found unfit, or for an adult who cannot make or communicate safe decisions about personal care due to a mental or physical condition. Common adult situations include advanced dementia or Alzheimer's, severe developmental disability, and traumatic brain injury or stroke.

The process runs through the Probate Division of the Circuit Court in the county where the proposed ward lives. An interested party files a petition naming the proposed ward and proposed guardian and explaining why guardianship is needed. All close relatives and the proposed ward receive formal notice and may object or propose an alternative. The court typically appoints a guardian ad litem to investigate and report, and usually requires a medical or psychological evaluation. A hearing follows, where the proposed ward has the right to attend and to be represented. If the court finds clear and convincing evidence of incapacity, it issues an order and Letters of Guardianship specifying the guardian's powers.

# Limited Guardianship and the Least Restrictive Alternative
Missouri law favors the least restrictive arrangement. A limited guardianship grants authority only over specific decisions, such as health care, while the ward keeps control over the rest of life. Full or plenary guardianship grants complete authority and is reserved for total incapacity. Courts will not award broader authority than the evidence supports. Where possible, less restrictive tools come first: a durable power of attorney for finances, a health care power of attorney for medical decisions, a representative payee for Social Security, or a trust, all of which require the person's own signature while they still have capacity. Once capacity is lost, court-supervised guardianship may be the only option. Guardianship can be modified, limited, or terminated, and ends automatically when a minor ward turns 18.

# Decision rule
If a person can still understand and sign documents, then use powers of attorney and other less restrictive tools instead of guardianship. If a person cannot make or communicate safe decisions and no prior documents exist, then petition the probate court for the narrowest guardianship the evidence supports.
