If you send a certified letter then hope for the best that guy will actually go to the post office and pick it up. Going to court is sometimes a big waste of time and, yes even money.
Hopefully what happens is that at the first court date, he will not appear, therefore giving you the win. Do you know what you do after actually succeedeing though? You have to figure out how to get the money from the guy.
Hopefully he has a bank account, b/c he is given a form to fill out that lists his asstes and any accounts he has. MAKE sure he fills all that out.
After you get that info. from him, it is your job to find someone to take that money out of his account (it's legal!) And if he doesn't have an account of any sort, then you need to find someone to go to his house and they will take shit outta his house and auction it off and give you the money.
It's actually time consuming but you may want to let him know, that if you file, this will go on his credit record against him. I have a family memeber who has gone through this bs so I know too much about this. Good luck, man.
