Kinship is reckoned bilaterally. Fictive kinship in the form of godparenthood is of social and ritual importance, but as godparents tend to be chosen from within the bilaterally determined consanguinai kin circle (grandparents, aunts, or uncles) it does not usually result in the extension of kin-based rights and obligations beyond the preexisting family group. The single most important kin group is the nuclear family. The term pariente (kinsman) refers to all consanguineal relatives, but family loyalty tends largely to focus on one's siblings and parents. This loyalty, however, is frequently contradicted by disputes, particularly over inheritance.
