Criminal records were maintained by courts in each municipal county in the United States. A county is a specific location, referred to as a sub-unit of regional self-government within a larger jurisdiction. But aside from county level courts, there are also municipal, state and federal level cases where court records were also stored respectively. There are about 3,000 counties in the United States of America, and usually court records are stored in county courts where county level cases are held.

The courthouse can be considered a whole new different world. You are required to follow certain rules once inside the premises. Before entering, you must submit yourself to a security search. Do not bring any form of weapons such as pocketknives, guns, etc. with you.
