It also depends on when you prefer to start appointing such power to your agent as well as when you want the power terminated. 1. General - This legal document allows the attorney-in-fact to act for the principal in almost every aspect of his or her life. It even authorizes the agent to gain access to the principal s safety deposit boxes or to handle all the properties of the principal. Power of attorney often has a scope, depending on the agreement or the dictates of the principal. In most cases, the power of attorney will only have an effect on specific cases or issues. Some will be stating a specific period of time while others will be point to more specific business dealings. For instance, a power of attorney may be granted to sign a business deal with Conglomerate X but will not be effective when signing deals with Conglomerate Y even if they are signed on the same day. The agent should just follow your instructions or directions especially if you are still very much capable of making your own decisions. Thus, it is like you are just sharing your authority or power with another person. In the same way, you could instantly revoke the authority you gave your agent anytime you like especially if you think you are dissatisfied and are dubious about his or her performance of the duty you gave him/her. Age It is a basic factor in determining whether someone is fit to become your attorney-in-fact. You must choose a person who is a lot younger than you are since he or she can carry out the responsibilities for a longer time compared to the older ones. Also, younger people are relatively healthier than their older counterparts, so you can be sure that they can handle your assets without much hassle. Consider a Health Care or Medical Power of Attorney If you have already reached the prime of your life, it is a wise move to create a power of attorney that designates a trusted person who will make choices regarding your health care and finances on your behalf when you are no longer mentally capable of doing so. Nobody would want to go morbid and prepare for something like dying from an illness. Death is easier because the will (as in the last will and testament) will take care of the legal matters post-mortem but dying is another thing altogether. This is especially true with people who are gravely injured and cannot make decisions for themselves like for instance when they are under comatose or when they cannot speak, move or are invalid.
