What is the benefit of having my record sealed or expunged?

The moment you are arrested (or receive a Notice to Appear in Court) you have a criminal history that is maintained by the Florida Department of Law Enforcement. But when you have your record sealed or expunged, it is no longer a public record:

A criminal history record ordered expunged (or sealed) that is retained by the department is confidential and exempt from the provisions of s. 119.07(1) and s. 24(a), Art. I of the State Constitution and not available to any person or entity except upon order of a court of competent jurisdiction**.”

**This subjects anyone that discloses it to liability. Liability is not automatic but the possibility is usually enough to have most private companies remove the information from their records as well.
