I agree, in Nebraska you do not designate your spouse or next of kin as designee...it automatically happens legally. I am sorry if that was not clear.
That's a bummer.
In my neck of the woods, you can designate who you want. I have no spouse or children...have a brother...but I designated my best friend instead. Not that I don't trust my brother, but he's never home...keep thinking if I needed him to make a decision, he wouldn't be there. My friend is more available.
