Both in Catalan, Spanish and Colombian positive law, there is a deep-rooted socio-legal tradition that supports the reserved portion based on the principle of interfamily solidarity, which complicates the application of radical theories such as the suppression of said public order institution or its configuration under strict need parameters of the heir-at-law. However, the legal provisions of new causes of indignity and disinheritance such as family abandonment, as well as the reduction of the reserved portion in Colombia glimpse a greater freedom to make wills as a logical trend in today’s society.esDisinheritanceFamily abandonmentInheritanceInheritance lawReserved portionWillArticle
