The first step is to choose someone to be your executor. This person will carry out your wishes as laid out in the document. Once you have chosen your executor, you need to draft the document. This document should include your wishes for medical treatment, as well as your funeral arrangements. After the document is drafted, you will need to get it notarized. This can be done by taking it to a notary public and having them sign and stamp it. Once the document is notarized, you should give copies to your executor and any family members who need to know your wishes.
