I may have him do that... but if the law is such that I can legally speak for him then that should be legally sufficient should it not?
no, it should not. if you want to be absolutely positive then get it in writing. the termination of life should NEVER come down to hearsay even between spouses. it would be for your own protection and that of your husband. they are available online, it is hardly difficult to accomplish.
Don't make the same mistake the Schiavo's and the Schindler's made.
Life is filled with things you think you'd never do, and you may not really know what you'd want in a certain situation until you're in it. I don't suppose I would want to live the way she's living, but on the other hand, if my family wanted me and I knew it, I think that might make the difference.
