Actually, he did know the MIL was part of the package deal - he ensured that the pre-nup stated she wouldn't interfere in their lives. The wife said he didn't take care of her and the child - what it sounds like is, he got her pregnant and then girl's mother must have "forced" him to marry the girl so the child would have a father legally. Note that the marriage only lasted 4 months and during that time, there was a child. Start counting.

What the cad is, is an irresponsible scum. And a pre-nup? The poor girl must have been so emotionally distressed that she was willing to sign anything and to be stuck in a jam with a mercenary, selfish, low down, etc.@#!! I pity the other poor girl who's now involved with him. She may think all is hunky dory for now, but a leopard does not change its spots. All the money or good looks (assuming he had any) in the world is not worth that sorry excuse for a man.

/Having said that, not all men are like that cad. Most are not. This one just takes the cake, and has earned his moment of infamy.

//Alternative possibility - the child was not his and the ex-wife was sleeping around and thus, he didn't feel the need to be responsible? Yeah, hogwash. If he wasn't responsible, he wouldn't have married her at all. Much less think up a pre-nup agreement - pre-meditation. He had enough time to think, plan and strategize. I've changed my mind. He's lower than a scumbag. The plan looks like get the pre-nup so easier to prove in court the minute the MIL tried to protect her daughter. "Interference" can be interpreted in many ways.

If the mother was defending her daughter (the ex-wife) against that useless husband, she might have been aggressive too, and that's easily interpreted as "interference". A few of those instances and reference can be made to the pre-nup, stating that it was agreed upon that upon these conditions happening, both parties agree to a divorce being granted.

- Hey, did the ex-wife's lawyers think up undue influence and duress, negating actual consent / agreement to that pre-nup, thus arguably making it void?
- But on 2nd thoughts, poor girl might just want to let it go, put this behind her and get on with life, which would be wise, I guess.
