The amount at issue is below the $25,000 limit for General Sessions court, so you may take out a Civil Warrant in General Sessions Court for your County. One thing to consider is your ability to collect. If the person who owes you the money is out of state or does not really have any assets, then the cost to file the suit (typically $119.50) plus the service of process charge ($35-70) is almost half the amount your are owed. If you are successful, you can recover these costs, but again, only to the extent he has assets.
