The issues require a review of the agreement to determine if it is an unconscionable agreement (terms so unfair no one in their right mind would sign) and an understanding of the circumstances occurring at the time of signing. You really need to meet with an experienced attorney.
There are a number of issues that have to be addressed to prove fraud or duress. The burden is on the party attacking the Agreement to prove either of those defenses. Find an experienced attorney in your area to review the agreement and the circumstances leading up to the execution of the Agreement to determine your exposure.
