In addition, no government reports could be officially approved and sent to the capital until it was countersigned by civil officials sent south by the emperor.
For example, a contract or other official document signed by the representative of a company may be countersigned by his supervisor to verify the authority of the representative.
Learner drivers may also be required to complete a logbook of their driving experience, which must be certified or countersigned by a supervising driver or driver trainer.
