I was just served papers stating that I am being sued by Chase bank for a past due credit card. In December I called and arranged a settlement and paid the agreed upon amount by the date stated. I have the Settlement agreement letter, a copy of the cashiers check, and a letter from Chase stating that the account is now paid in full. The court documents state that I have 30 Calender days to respond. How do I go about responding to this? What forms do I need to fill out for the CA courts? Can I countersue them for a wrongful suit?
