the statement may come to the address of the person who is using them, hence, he or she kicked the X out when it all crashed and burned. Still gets that mail; forwards the rest to the X, or changed the address of the rest so the X gets it when it comes.

Statements are often electronic anyway.
I know that right now, my wife, who knows of miles and has many of them, has no clue of exactly how many she has. It is me who manages the accounts of these things in my family. I do 90% of this online and the occassional mailing goes to me as well. In fact, I manage them for my own mother and when she wants to fly, I help her pick the airline. Our family basically shares them all too. When dad died, I managed those accounts and had the airlines transfer to people in the family based on what they had. Mom provided the executor statement to me and told me to take it all over for the family. One brother was a DL flyer so he got all those points, the other a CO flyer, and I was AA so I got all those, and so forth... Mom got the starwood points and there had been many. She would get the mail on airline or hotel stuff from dad's accounts and give it to me. She now has the Amex too and gets more. She has no idea how many and still likes to write them checks to pay the bill. I tell her how many points she has when we meet and she sometimes passes it off as trivial. Yet, when it comes time to stay somewhere she likes this info! I know my mother has no idea, nor does she really concern herself with who has what because she knows my brothers and I will share awards when needed. My wife and my mother just let me do all this stuff and my brothers love to hear about the easy promos they can do with less effort than an average FT addict may be used to.

I do know this: If my wife and I ever got divorced, she'd probably let me have all the miles or use of her accounts (in fact, our arguements would be about miles and that would be why she left me--hee hee hee) But I know this because she cares less about them than I do. She would go back and live on the farm where people dont fly that much anyway.
ha ha ha

I'd just be out of luck all across the board because she is a great girl and I would not want to ever lose her! Well, it wont happen, but each couple has their own thang...
