Under the laws of all states in this country, the only person who can legally sing a document as a co-signer is the person who actually co-signs the document in such a capacity. In your situation, I would contact the pay day loan company and advise it that you never signed any document concerning your daughter as a co-signer if this is the case.If you daughter designated you as a co-signer on her loan without your consent and knowledge, what she did was improper.
