Civil status

Births, marriages and deaths are recorded in German civil registers. In Germany, these registers are not kept by the town halls but by separate civil registry offices. In principle, a civil status event is always recorded in the register of the civil status department of the district in which it occurred.
In general, modern civil status begins in 1876. With a few exceptions and in some Länder: 1792 in Rhineland (French departments under Napoleon),1803 in Hesse-Nassau,1808 in Westphalia,1809 in Hanover,1874 in Prussia.
Registers for very old events are archived at regular intervals: 110 years for birth registers, 80 years for marriage registers and 30 years for death registers.
