They have not been used by traditional Catholics. They have been used be people who don't care about protecting the permanence of marriage or making sure the prenup is compatible with Church teaching.
What’s so “special” about a Trad divorce? If a prenup is ever needed (God forbid), then permanence of marriage and Church teaching has already been TRASHED by one of the spouses who is requesting a divorce. It’s not the lawyer’s fault that the marriage broke up and there’s nothing he can do to fix it. All he’s there to do is make sure the divorce is fair to both parties, per the agreement.
A prenup is a tool, just like a weapon. If you’re trying to blame the prenup for a divorce then you should blame the gun for the murder. But we all know that logic doesn’t work.
