Seniūnaitija ("sub-eldership") is the lowest level administrative-territorial unit in Lithuania. Seniūnaitija is led by a seniūnaitis who represents communities of inhabited places. Seniūnaitis are elected for a 2-year tenure.
The amendment of the law on 15 September 2008 describes the regulations regarding sub-elderships.[1] The first sub-elderships established by municipalities appeared in November and December 2008, and by 2009, most of municipalities had established sub-elderships.
