I work for a local rock band. Last June while I was moving some equipment, one of the larger and heavier cases on wheels rolled through a portion of the parking lot and hit another vehicle belonging to the valet company who are a third party of the venue I was at that evening. Minimal damasge was done to the company vehicle and information was exchanged. No one has contacted me about this incident from the venue, parking company or a vivil lawsuit. How long does anyone have to bring a case against me?

In Georgia, this type of legal action would need to be started before two years expires. This is commonly called, "The Statute of Limitations." If an appreciable amount of time has gone by without any contact from the guy with the damaged car, then perhaps you won't have to worry about a lawsuit!
