Episcopal consistorial office in České Budějovice was created in 1784 and 1785. Since its origin it has been one of the most modern offices not only on the teritorry of Czech lands but also in the whole Habrburg monarchy. It produced all known kinds and types of documents including verified copies of documents, called traditionally by the Church customs as the "autentisatio" and "legalisatio". This paper focuses especially on the relationship between them, comparison with common vidimates and confirmation papers, official practice of production of these verifications and confirmations, legal consequentions, formal differences, practical using, as well as their development to 1850.
