What is the legal definition of medical power of attorney?

Basically, Medical POA gives you the authority to carry out the principles wishes and make decisions concerning their health when they no longer can. This could be because of Dementia or in a coma. It is only in effect when the principle is not competent to make an informed decision. My Moms Medical POA read like a living will.

As suggested, check with the rules of your state.
