Casa de la Val is a historical house in Andorra la Vella, Andorra. It was the seat of the General Council of Andorra until 2011. It lies just to the southwest of the Andorra National Library. It is a heritage property registered in the Cultural Heritage of Andorra.
It was built in 1580 as a manor and tower defense by the Busquets family. In 1702, it was acquired by the Consell de la Terra.
The first Paréage of Andorra (Catalan: Tractat de pareatge) was a feudal charter signed in Lleida on 8 September 1278. It codified a lay and ecclesiastical agreement between the Count of Foix, Roger-Bernard III, and the Bishop of Urgell, Pere d'Urtx, establishing their joint sovereignty over the territory of Andorra. The paréage established the system of condominium in Andorra, placing it under suzerainty of both lords. This system was later ratified in 1993 by the signing of the Constitution of Andorra. The charter underpins the modern legal status of Andorra.
A second paréage was signed on 6 November 1288, which supplemented and addressed a number of clauses in the first paréage. Together, these two paréages comprised the first basic law of Andorra, and were the nation's most important constitutional documents until the ratification of the Constitution in 1993.
