My ex-wife's brother-in-law and sister are suing me for a $5,000 loan made to my business in 2008. I did not want the loan and do not remember signing a promissory note for it. My ex-wife basically did this without my consent and I know she was the one who endorsed the back of the check with my business name and account and deposited the check. She then proceeded to use the funds for other purposes (she had access to my business account--I know, I am dumb). I am requesting a copy of the promissory note from the attorney who is suing me (their family member) but he refuses to give me a copy (I believe my wife forged my signature) and does not tell me why. Am I, by law, entitled to a copy of the note so that I may defend myself (with or without counsel)? Is the refusal illegal?
