The Last Will and Testament is a legal document that directs and governs how your property will be transferred to others upon your death. There are formalities to a formal Will that must be followed, for example a proper attestation by witnesses. Trusts may be used inside complex Wills. An Executor, also called a Personal Representative, will be responsible for probating the Will at Court, and for carrying out the Will’s provisions.
The General Durable Power of Attorney is a legal document that empowers another person, called an Attorney-in-Fact (meaning, Agent), to be responsible for carrying out your business affairs. This person can collect money owed to you, pay bills you owe, handle your bank accounts and investments, and buy, lease, or sell property in your name. You can make the Power of Attorney effective once it is signed, or delay its effectiveness until you are disabled from carrying on your own business affairs.
The Health Care Power of Attorney is a legal document that directs and empowers another person, called an Attorney-in-Fact (meaning, Agent), to make health care decisions on your behalf. This Power of Attorney is usually drafted so that your Attorney-in-Fact only makes such decisions for you after you become disabled and unable to communicate with your medical providers.
The Living Will is an advance directive to the medical providers who will be attending you at the end of your life. Since you may at that time be disabled from communicating with your medical providers, the Living Will allows you to record ahead of time your wishes for the treatment you want to have, and the treatment you do not want to have, at the end of your life. An example would be your choice as to the continuation, or not, of artificial feeding after your physician has concluded that you will not be recovering from your terminal condition.
