Each year, you are entitled to a free credit report. This credit report will contain most information you seek regarding past addresses, financial obligations, and other information that you will find useful in completing your Florida Bar application.
Make sure you are using the United States government Federal Trade Commission website and their partner Annual Credit Report.com, an approved method for obtaining your free credit report. Some sites may say "free" but then have hidden costs.
It is a good idea to obtain your credit report in general. Take the time to do it.
