Avance health care directives or advance directives are instructions given by an individual specifying what should be done for his or her health in case he or she is no longer able to make decisions. A living will is one type of advance directive. It is often accompanied by a specific type of power of attorney or health care proxy. These are legal instruments that are usually witnessed or notarized. It is often encouraged that people complete both documents to provide the most comprehensive guidance regarding their care. Studies have also shown that adults are more likely to complete documents written in everyday language. One example of a combination document written in everyday language is the Five Wishes advance directive.
