While there could be differences in the type of information you require, generally, there are 3 common ways people use to perform their checks:
1. Search public records at the government offices of agencies
Depending on the type of the information you need, you can search in courts, schools, churches, public archives, trade associations, etc. The task can be quite tough, especially if you have to search in other states and in a number of establishments. While some records are available for free, many of them are not, and you can end up paying quite a sum, especially if you are compiling a detailed dossier. This way to search public records may be effective, but requires a lot of time, effort, patience and, in some cases, money.
2. Hire a Private Investigator
Call it a detective agency or middleman, the idea is to involve a third party to perform a complete or partial search for you. No doubt, if you deal with a professional you can expect perfect results in a short span of time; however, you should realize that not everybody can afford such services. If you are just curious about your potential date, hiring a professional detective is a way too much for such a minor thing. If you want to perform background check of your employees, the investigation can cost you a fortune.
3. Search public records online.
Nowadays, such public records are archived and organized in huge databases for easy reference online. Such information are compiled from multiple reliable sources and updated frequently. They are paid services but often made available to the public for a very nominal fee to search public records. It costs a little more if you want to perform unlimited searches. The information you want is compiled quickly and presented to you in a detailed report within seconds, and not minutes or hours.
