consent to judgement

Little bit of a issue...We have been fighting said bank for 3 years, basically business went bad and what was lent (to one person as a sole trader mind you) well out weighed security as it stood and basic income. They gambled on us and it failed, but they never lose. Any way its been so hard to clear our creditors but we did it (150000.00 18 months) and all we want from the bank is to work with us to sub divide the security ie leave us alone , we have the cash to finish both properties and it would take 4 months we walk out both go on the market once sold the bank puts its hand out and whatever is left we get and get on with life again. But no they want deeds signed, 2 now, that we pay 1650.00 p/w until all monies are paid in full to them, and on this is on 450000.00 owed with finished security sale price total 525000.00. When business went bad we defaulted on every thing we were paying for about 12 months. We didnt go bankrupt, or run away we stood up and worked our asyt off. OUR ISSUE RIGHT NOW IS THIS 2ND DEED MY MRS SIGNED THE CONSENT TO JUDGEMENT NOT KNOWING WHAT SHE WAS SIGNING SO R WE FU#$ED........OR IS THERE SOME CONTRACTURAL LAW WE CAN USE.
I have a list of complaints that i have only found over christmas (first time i have had some time to dig through paperwork)
ok
initial interest rate on letter of offer was x% and the statements from start to now are .66% higher, broker sold to us fixed first x years bank offer dropped a year of that, broker, bank, settlement agent and lawyers reports to me once they all did there bit show massive discrepincies in aloccation of funds and costs for same items. the bank then lent on a loose facilty 75000.00 to one person earning under 50000.00 p/a then increased the facilty by another 850000.00 and down the bottom of the offer ... repayments as follows..44 days later facility to be reduced to 120000.00 and 182 days after that back to 75000.00. no statements say we can do any thing like that.
any way im only posting in here with the hope someone sees this that has qualifications and knowledge to help us sort through our mess.
We have not accrued a debt in 18months have letter from bailiff stating repayments etc...and earn well over enough to service a proper product.
Or bankruptcy and move on.
Thanks in advance
