Can an attorney sue me for failing to pay him? I got an angry call today from an attorney who helped me with a case in december of 2012,he charged me 1000 dollars total and I had already paid him 500 in december, I had every intention to pay him and I do have the money, I just want to know if he can legally sue me even if he never gave me a due date for the total amount nor did he send a written notice/invoice. Anyhow, he called my cellphone today and told me that I was taking advantage of him and that he was going to sue me if I didn't pay him tomorrow. He raised his voice at me and acted as if I had been ignoring his calls or attempts to collect the money. There were never any previous attempts neither by call or written.
