GM, I think what you are feeling is entirely normal. As we know the divorce system metes out some fairly rough 'justice' and these entitled MLCers feel the victim in all of this. I guess if the starting point is that they want it all, anything less feels like a huge rip off to them.

My guess is that your xh is agreeing to mediation because it suits his agenda. I have learnt by biter experience to be on my guard any time my xh does 'nice'. He wants something and expects to get it.

Presumably the object of the mediation is to agree that your xh owes you something, and that the overall cost will be lower than going to court? Plus quicker.

Will mediation also mean that your xh can't revisit this when he gets another vindictive fit on him? Can it be 'sealed' by the Court?

Nothing about MLC is remotely 'fair'.
