An advanced directive is defined as a legal document that takes effect if one cannot make decisions due to illness or incapacity. Several different types of advance directives exist. Some, such as a living will, give instructions on which measures can be used to prolong life. Others simply name a surrogate decision-maker for medical questions. Different jurisdictions will generally have their own laws regarding different advanced directives. For instance, NY § 400.21-Advanced Directives states its definition, elements, purpose, etc.
