A Medical Power of Attorney is a legal document where the principal entrusts an individual (the agent) to make medical decisions on the principal's behalf. This document will help people make decisions when they are unable to do so. The agent can be anyone you trust, and you had better choose your spouse, child or intimate friends. The principal who creates this document must be 18 years old or older and is capable of making the appointment. Anyone who is interested in this document can take the General Medical Power of Attorney Form for reference.
