Usos y costumbres ("customs and traditions"; literally, "uses and customs") is the indigenous customary law in Hispanic America. Since the era of Spanish colonialism, authorities have recognized local forms of rulership, self governance, and juridical practice, with varying degrees of acceptance and formality. The term is often used in English without translation.
Usos y costumbres political mechanisms are used by numerous indigenous peoples in Mexico, Guatemala, Bolivia, and other countries to govern water rights, in criminal and civil conflicts, and to elect their representatives to regional and national bodies.
