Could be. But remember there are three sides to every story, and that is never more apparent than in a messy divorce. Every non-amicably divorced person I know will tell you (sometimes without prompting;)) that they are the one who was screwed over in the divorce. My husband’s ex-wife left all the possessions with him, took the children and moved out of state while he was at work. He came home to find the empty house and a note. He repeatedly tried to give her back all of the marital property (furniture, electronics etc.). He did not want it and it and repeatedly tried to return it to or get her to pick it up. He was active duty military at the time and they lived in base housing so the actual house was not involved. The day he discovered his wife was gone he set up a voluntary allotment transferring more than half his pay and allowances to her as spousal/child support until it could be set up through the courts (as an aside spousal support was eliminated and child support was granted at a much lower rate than he had voluntarily given her until he got full custody of the kids a few years later). BUT to hear her tell it, she was completely screwed over in the divorce and he took her for everything she was worth and ruined her entire life to this day (now 13 years later). My point being that such sob stories (mine included!) should always be taken with a grain of salt and remember that much of it is going to be a matter of perception.
That sucks. It is always hard and sad, and especially tragic for the children involved, but do you think it would have been any better if they had a pre-nup?
If so, then how? If there had been a pre-nup stating Mom gets XXX and Dad gets to keep XXX in the event of divorce (or vice versa) what would have kept one of them from disputing it or trying to change the terms (claiming unfairness or change of circumstance or what have you) or fighting over the areas not covered by the pre-nup. If a divorce is going to be contentious and litigious, then having a pre-nup just gives more points to argue about and more cause for courtroom involvement.
