Since abuse was involved I'd contact the Domestic Abuse people and their recommended solicitors Toula. I have no way of knowing if work can be done at reduced rates if solicitors are funded or part funded but there must be a heck of a lot of women who need this help.
It has changed a lot since last April when No Blame divorce came in in terms of complete separation, but finances still rely on both parties negotiating and if not in agreement court proceedings. Both parties have to fill in financial forms and failure to declare all assets is not likely to go in his favour.
Under No Blame divorce the financial forms, even if agreement, still have to go to a court for what is apparently rubber stamping - but there is an element of duty of care there too - if things look as if one party has been severely disadvantaged, even if agreed it wouldn't go through. Needless to say, quite long waits with backlog of cases.
However, even the finance side was simplified to some extent. (Info from solicitor who helped me)
I'm sorry you had to go through so much, GSM, and you knew the ropes too. The hell of abuse is bad enough without the protracted money and will he won't he what will he do worries.
