What is the process of suing in a Nevada civil court for unpaid rent?

suing in civil court: I want to sue my daughter's ex-boyfriend for unpaid rent. He lived w/my daughter for 18 months, 3 years ago in a rental house that I own. We had a verbal agreement that he would put rent money towards down payment on a house they were going to buy together. He did not do so. Six months after they moved into a new house (w/no down) he cheated on her and they split up. He has acknowledged in child custody papers that 1. he lived in my house for 18 months and 2. that he did not pay save any of the rent money as agreed. I want to sue him in civil court. He is a cop & thinks he can get away with anything. - Is this your question? Add additional information
