The Chancellery of the Riigikogu was established by the Riigikogu resolution of October 5, 1992. The task of the Riigikogu Chancellery is to create the organisational and economic conditions for the successful work of the Board, members, committees and factions of the Riigikogu. The Chancellery assists the Riigikogu in preparing draft legislation by providing necessary legal advice and obtaining economic, sociological and other information. The legal acts to be adopted are edited and given their final form in the Chancellery. The Chancellery also informs the public of the activities of the Riigikogu and takes care of the appropriate use of the state assets belonging to the Riigikogu.

The salaries and pensions of the Riigikogu members are also paid through the Chancellery.

The work of the Chancellery is directed by the Secretary General of the Riigikogu who is appointed by the Board of the Riigikogu after public competition.

The Chancellery fulfils its tasks through departments and services.
