I have been asked by multiple different companies on different occasions to sign documents, with my signature certifying that all information in the document is true and correct. These documents have had factual errors, and further, when I request a correction, the companies always insist that I sign the document anyway.
Is this inherently illegal, and if I were to sign as instructed, does their action affect the validity of contracts derived from this information or the validity of my signature, at all?
