Members are elected by halves in staggered elections for four-year terms every two years using the limited voting system (similar to that of the Argentine Senate), and using the ley de lemas for party lists.

Since 2019, the post has been occupied by Eber Solís, elected in the Justicialist Party ticket alongside Governor Gildo Insfrán.

This first legislature, by the name of Chamber of Deputies, comprised 30 legislators elected by halves every two years for four-year terms, with possibility of re-election.

[3] The Chamber of Deputies has its seat in the Legislature building, on José M. Uriburu 241, Formosa.

An eight-story building by San Martín Square was originally planned during the 1980s, but was never finished.
