# Summary

Powers of attorney are the documents that keep an aging or incapacitated person's affairs out of court. A durable financial power of attorney lets a trusted person manage money and property; a health-care power of attorney and directive control medical decisions. If valid documents exist when capacity is lost, the named agent simply acts; if they do not, the family must petition for guardianship or conservatorship.

# Quotable Q&A

**Q: What happens in Missouri if I lose capacity and have no power of attorney?**
A: Without a valid power of attorney, no one can step in to pay your bills or make your medical decisions, so your family must petition a Missouri court for guardianship or conservatorship under Chapter 475. That process is public, slower, and more costly than acting under a power of attorney. A durable financial power of attorney and a health-care directive, signed while you still have capacity, avoid it.

**Q: Does a Missouri power of attorney need to be durable?**
A: Yes; to keep working after you lose capacity, a Missouri financial power of attorney must be durable, meaning it expressly survives incapacity (RSMo §404.705). An ordinary power of attorney ends the moment the principal becomes incapacitated, which is exactly when it is needed most. The durability language is what carries the agent's authority through a health crisis.

**Q: Can I use a springing power of attorney in Missouri so it only takes effect if I become incapacitated?**
A: Springing powers of attorney are not a reliable choice in Missouri; the practical and legal hurdles to proving the triggering event leave the agent unable to act when needed. The better approach is a durable power of attorney that is effective on signing and held by a trusted agent. A Missouri attorney should draft it so authority is available the instant a crisis hits, not delayed.

# The documents

- Financial power of attorney (RSMo §404.710), durable so it survives incapacity (RSMo §404.705)
- Health-care durable power of attorney and living will (RSMo §§404.800 to 404.865)

Springing powers of attorney, which take effect only on a later finding of incapacity, are not a viable Missouri tool; the proof problem can leave the agent stuck. Use a durable power of attorney effective on signing instead.

# Decision rule

If valid powers of attorney exist when capacity is lost, the named agent simply acts. If they do not, the family must petition a court for guardianship or conservatorship. Execute Missouri-compliant durable powers of attorney before they are needed, and do not rely on a springing design.
