Hi, my ex-partner in business sent me a minor case claim around $45,000. How do I respond to it? The amount and the claim he is asking are 99% invalid and he doesn't have any proof/agreements or any base. What should I do? Do I have to defend it and get the lawyer to deal with it? Or do I do it myself? I haven't done it before and if I ask lawyer help, how much would the lawyers fee cost me? He was the one who was taking care of the accounts. I didn't have any clue.
