Probably a good time to get a lawyer. If they knew that the loans weren t current and they stated that they were, it s fraud plain and simple. It s harder to prove if something wasn t signed, but generally you van prove that this was agreed upon by sworn testimony of a witness. The exception is that if the contract specifically states that nothing outside of the agreement was implied, etc...What sort of documentation was signed?Generally, you do not want this to go to lawsuits because civil litigation is extremely expensive. Based on your description, I would say they committed fraud and your refusal to pay them would be a default on whatever agreement you have. Just because they broke one part of the agreement doesn t dissolve the agreement or allow you to break it as well.
You should have had everything in writing. If there was only a verbal agreement about loans being current then you are in a heap of trouble. They can come after you for every thing you owe them and the lien holder can kick you out of the business. However you could go to the lien holder and explain the situation, maybe they will work something out with you. good luck.
