Late Middle English (as a verb in the sense ‘check or verify accounts’, especially by referring to a duplicate register): from Anglo-Norman French contreroller ‘keep a copy of a roll of accounts’, from medieval Latin contrarotulare, from contrarotulus ‘copy of a roll’, from contra- ‘against’ + rotulus ‘a roll’. The noun is perhaps via French contrôle.
