Consumer Law, Warranties Asperger's Syndrome and Contracts

[dmdavis2]

I have Asperger's Syndrome, I am 53 years old. In 1989, I was involved in a contract. Fraud was found in the lat 2 years. It was as a bad business deal. I was unaware at the time. I know nothing on legal issues. I was just going to sign it and get away from the bad times I was having at work. My wife was ask to sign too. I told her to sign, she did not read the contract. I just wanted to get out of the hopeless situation and need money.
Is there anyway to go back and have the courts review the contract for fraud. Also, if it matters, I was unaware of the outcome until now.

Thanks

Mark
