Is this the same as a Will?

No. An Advance Directive (also known as a living will) is for when you are still alive and is your legally protected instructions about the type of medical care you want if you can’t make medical decisions for yourself (e.g., you are in a coma or on life support). A Will (or Last Will and Testament) is only relevant after your death and instructs how you wish to distribute your money, possessions, and property.
