"They" being your W and her L? My XW pulled something similar, objected to the settlement at the very last minute. The settlement that SHE drafted up. She sent me an email stating that she wanted to adjust the settlement amount upwards by 7k or so, and the reasons (I kid you not) were complete gibberish that made no sense at all. I asked her if we could meet to review it and she blew her top for absolutely no reason. Said "no forget it we'll just let the lawyers fight it out in court, and I promise you will NOT come out on the better end of it." I explained to her that I just wanted to understand her reasons as the email didn't make sense. Nope, she didn't want to talk about it. Up to that point everything had been handled quite amicably, I have no idea why the sudden change in her. After thinking about it a few days I told her I still didn't understand her reasoning, but trusted that she felt it was fair and to modify the paperwork and I would sign it. And that's what we did. I probably would have spent at least 7k in legal fees (and she would have too) trying to battle it out with her, and the thought of a long, drawn out court fight just had me spiraling all over again. So that 7k was worth my peace of mind!
