One of the fundamental, and according to some, the most important and most authoritative records on the personal status of an individual are civil registers. Numerous indirect and direct legal and other sources that are mentioned in this paper speak about the importance of the existence of civil registers. The work itself starts with the historical development of civil registers both on European ground and in our region. What are civil registers, what types do we distinguish and which extracts and certificates from civil registers are issued as documents of permanent value, and who has the right to insight state registers represent the majority of this work. Ultimately, the paper also deals with registrars as civil servants and their basic powers and duties in the implementation of various laws and by-laws, as well as the responsibilities associated with the performance of that work and possible sanctions if they are not followed. The goal of this work is to bring the reader closer to the concept of registry office in general and to provide new knowledge that can be used in everyday life and work.
