If some one was cautioned in 1989 (prior to PNC) and later changed their name by deed poll then again by marriage and moved right away from the area where the caution was given, how likely is that caution to show on a CRB disclosure?
i would've thought that any applications or searches would request your current name and any previous names, so in that case, likely. do they not 'port' any history linked to your previous name over? either way, not providing your previous name(s) is a criminal offence carrying a sentence, but a caution isn't a 'criminal conviction' in itself
