With respect, you should check the terms of the settlement that was agreed with your wife - because it may well be worded in the form of a compromise agreement, the terms of which could prevent B&Bcoming after you for any part thereof ? They should be put to 'strict proof' of their claim and the amount of the debt if they wish to go to court.(posted 6982 days ago)Further, I would respectfully suggest that if your circumstances are changed in a negative way, by going to Court B&B may be shooting themselves in the foot, as the Court can only award certain specified amounts as payment, and this may be less than you are already offering to pay. Don't forget on any I&E to include 'everything' - laundry, cigarettes, extra groceries (especially if you have special dietary needs).
Should you want to see the effects of a compromise agreement and the many facets thereto, I suggest you obtain a copy of 'The Law and Practice of Compromise' 5th Edition by David Foskett, QC, (the so- called bible on the subject), from your main library (rather exopensive to buy but avaibale at Hammicks London in the sum of £160.00 net.
Good Luck !
