The General Council of Aran is elected every four years on the basis of universal suffrage, which comprises all nationals over eighteen who can vote in the local elections in any of the 9 municipalities that make up Aran.

According to Law 16/1990, of July 13, on the special regime of the Val d'Aran, it is made up of the Síndic d'Aran, the General Councilors (Occitan: Conselhers Generaus), that work in plenary, and by the Commission of Accounts Auditors (Occitan: Commission d'Auditors de Compdes).

Aran is divided in six electoral districts, whose borders coincide with those of the "thirds" (Occitan: Terçon, Catalan: Terçó, Spanish: Tersón), a traditional division of the valley.
