There are many different kinds of POA's and every state has different rules. Very basically, a POA allows you to sign for someone when they are not available. For a example, a military wife has POA when the husband is over seas ( if he signs one). A Durable POA is usually granted by someone who is ill or aging and they anticipate that sometime in the future they will no longer be able to make decisions or sign things. Then there is the Health Care Proxy (POA) where you are able to make medical care decisions for someone who is under anesthesia, in a coma, or incapacitated for some reason. Finally there is a court ordered Guardian. If the person cannot sign for a POA due to already existing incapacity, a Judge appoints someone.
