# Summary

A power of attorney matters while you are alive but cannot act for yourself, after a stroke, during surgery, or as dementia progresses. In practice, more families are harmed by a missing power of attorney than by a missing will. Without one, your family must petition a court for conservatorship.

# The documents

- Durable financial power of attorney (RSMo §404.700): authorizes someone to pay bills, manage investments, file taxes, and handle property. "Durable" means it survives incapacity.
- Healthcare power of attorney (RSMo §404.800): names someone to make medical decisions.
- Healthcare directive (RSMo §459.015): states your wishes on life-sustaining treatment.

# Decision rule

Every adult needs both a durable financial power of attorney and a health-care power of attorney. Without them, incapacity forces a public, costly guardianship.
