How can I find out if the abuser has been convicted of a crime?
Criminal convictions are open to the public, but they are not always easy to access. If you know the exact courthouse where the abuser may have been convicted, you can go to the courthouse and ask the clerk of court for access to those records.
Domestic violence misdemeanor and felony records are also kept in the National Instant Criminal Background Check System (NICS). However, no one other than law enforcement officials and licensed firearm sellers are allowed to search the NICS. Your local police department may be willing to search NICS for you if you ask, but they are not required to do so
