Thanks. Medical proxy is the term I've been trying to remember.

When Hubby and I filled out our Living Wills at the lawyer's office, we had to name three people in order for a "proxy" in case we were incapable of making decisions for ourselves. Our lawyer wanted us to name the three independently of each other, in other words, we communicated them to our lawyer without the other person in the room. Later when Hubby and I compared notes, we listed the same three in the same order!
