A Montana living will is a legal document through which an individual, which is referred to as the principal or declarant can choose to use or withhold life support when they’re ill. It can also share other medical directives such as what happens to their organs, funeral arrangements, etc. The use of this document is backed up by Title 50, Chapter 9 (Montana Rights of the Terminally Ill Act). It is however required, under § 50-9-103, that two include their signatures on this document.
As the principal/declarant, you are to fill in essential details like the date, your name, your signature, the city and county where you live, your birth date, and your social security number, on the form.
You are to do the above in the presence of two witnesses who are to first enter the date the form was filled, and then imprint their signature, enter their name and their mailing address to prove that you(the principal) were in your right mind when the document was filled.
