I'm guessing he wouldn't be fair, hence the need for a solicitor.
Surely he knows the statements are still going to you, so you have a good idea what should be left after bills
I have no advice
. My dh was married previously and him and his ex amicably sorted everything out without solicitors (no children), so was completely pain free and both were happy.
I can imagine the thought of it dragging on for a year very wearing.
Can you not appeal to his better side about this.....or hasn't he got one when it comes to holding on to his £'s?
