In some states like Massachusetts, Texas, Florida, Georgia, Indiana and more states a personal identification is required to make the request for search. You should contact your local courthouse in case your state wants you to make the request to find court records of a person in person. Here you will also know whether you have to pay fee for it or not.
Usually on television you will see the character accessing a database to find criminal court records or they hire a private investigator to tap out a few keystrokes and print out the total life history of a person without any effort. These types of databases that you see in television are now available publicly online. You can easily search court records online now. If you want to hire an investigator to lookup criminal court records of a person, then you have to pay a fee for it and it will cost much more than doing a search for court records on the internet.
The criminal court records do not include social security number. Therefore through social security number you cannot find criminal court records. To lookup a persons court records you can also approach the federal court system instead of the state or local courthouse.
