This has been a popular question lately. I don't know why, but a lot of people want to sue in small claims court. If you think you have a case, and it is under $7,500, go for it. But, how do you know who to sue? (This applies for individuals only. Businesses are a bit different.)
If you do not know the name of the person who injured you or damaged your property, you need to get it from the police or any agency that took a report, such as code enforcement or animal control. You can also look up public records to see who owns the home where the person lives, if you know. Once you have a name or names, you can file suit in small claims court. Contact your county court and ask for the small claims advisory clinic.
