Financial compensation is an intangible and post-matrimonial right, function of which is mainly aimed at indemnifying the party in question and, based on some other assumptions, has a complementary function or a function to exclusively provide assistance. This work applies said thesis to the waiver of financial compensation and sets inflexible solutions apart; it also criticizes the traditional civil Law solutions, away from a strongly analytic family Law and based on its own inherent principles, which makes it different from other areas of the Private Law.La compensación económica es un derecho extrapatrimonial y postmatrimonial, que tiene una función principalmente resarcitoria, y, en algunos supuestos, complementaria o exclusivamente asistencial. Este trabajo aplica tal tesis a la renuncia de la compensación económica, y se aparta de soluciones rígidas; y critica las soluciones del Derecho civil tradicional, alejadas de un Derecho de familia fuertemente analítico y sustentado en claros principios propios, que lo diferencian de otras áreas del Derecho Privado.
