In a Divorce Who Gets Custody Of The Friends?

I have friends who are in the process of getting a divorce. This wouldn't normally be so bad, except he is in my husband's Unit and she I became pretty good friends with while the boys were deployed. Every time there is an issue in the divorce it gets spilled out into the friendship, she always wants us to take a side. Personally I like to be "Switzerland" and remain neutral. I don't like to be dragged into anyone's business.

Recently my friend asked me to tell her when her husband soon to be x gets his promotion. I was a little taken back by this. I am caught in a caught 22. I decided for the best of all to go with the good old stand by of "I don't know."

My question is in a divorce who gets custody of the friends?
