The Rehabilitation of Offenders Act 1974 enables some criminal convictions to become 'spent', or ignored, after a set length of time from the date of conviction. After this period, with certain exceptions, an ex-offender is not normally obliged to mention their conviction when applying for a job or obtaining insurance, or when involved in criminal or civil proceedings. The "No Live Trace" or "Further Information Stepped Down" response indicates that information is available relating to a 'spent' conviction. A "No Trace" response indicates a clean police record.
Applicants presenting “No Live Trace” or “Further Information Stepped Down” police records are encouraged to request and submit their Subject Access Record to facilitate visa processing. Applicants are legally entitled to gain access to this information about themselves under Section 7 of the British Data Protection Act, 1998.
