The Living Will, also know as the Advance Directive, is a document that is beneficial in the event that you become terminally ill and feel that you do not want your life artificially prolonged, giving you ”legal say” to have medication stopped or a life support machine switched off. This provides peace of mind for your family, as they would not have to make such a decision at a very emotional time. If you make an advance decision to refuse treatment and then later make a health and welfare Lasting Power of Attorney which gives someone authority to give or refuse consent to the same kinds of treatment, your advance decision will become invalid.
Disadvantages of Advanced Directive – Can be challenged by the loved ones and doctors in case of “terminal illness” and could be overturned.
