WHAT HAPPENS IF I SIGNED A CONTRACT WITHOUT READING IT?

A friend told me about a contract he signed without taking enough time to read and understand his rights and obligations. The other party finally brought up some hidden terms in the contract that she never noticed. 
Now her question was; do you mean I will be bound by the terms of this contract?

Sincerely I wish you could escape from the terms and obligations of the contract since you did not read it before appending your signature.

However, when a document containing contractual terms is signed, then, in the absence of fraud or misrepresentation, the party signing it is bound by the terms of the agreement signed regardless of whether he has read or understood it or otherwise.
 
To avoid being burnt or having a scar, always get a lawyer to review your contract.
