Actually, the court can give him a 'gold star' for doing that. If he simply throws his wife out on the street with no money and no support, that can be a SERIOUS problem when they get in front of a judge. Furthermore, some courts will take into account the months that the payor is supporting the payee while the divorce is pending when they set the final alimony amount.
I would not simply stop paying without discussing it with my attorney.
Nobody suggested that he stop paying at all.
The court simply WILL NOT give him any credit for doing the right thing absent a court order. You know that and I know that. Forget the good will, courts don't acknowledge that unless they choose to do so.
Furthermore, nobody remotely suggested that he throw his wife out on the street with no money and no support.
You have far more trust that officers of the court will act in the best interest of clients than I do, and, you have far more distrust that men will do the right thing than I do.
Well here is an example of a man doing the right thing and getting screwed doing so by his lawyer.
Doesn't matter, because if he went before the court, it will be the same result.
