Abstract
The article analyses the legal basis and the scope of protection of correspondence against disclosure, as well as outlines formal and material prerequisites of the secrecy of correspondence. As it has been established, although the secrecy of correspondence is protected under the provisions of the civil, administrative as well as criminal law, the legislator has failed to define the notion of correspondence. This makes it difficult to set the limits of protection and mutual relations between the secrecy of communication, correspondence, mail, telecommunication, as well as other regulations providing for protection of certain information and data.
