Zuzuarregui v. Zuzuarregui

Summary

This landmark succession case established that illegitimate children other than natural children can inherit from their deceased parent's estate under the new Civil Code without formal recognition, provided filiation is duly proved. Antonio de Zuzuarregui died intestate, survived by his widow and four claimed illegitimate children who had lived as family members and were acknowledged by deceased in official documents. The Supreme Court affirmed that unlike natural children who must bring recognition actions during the putative parent's lifetime, spurious children need only prove filiation to claim inheritance rights. The decision liberalized inheritance rights for illegitimate children, reflecting the Code's policy against visiting parents' transgressions upon innocent children. The case demonstrates the new Civil Code's more progressive approach to family law and succession rights.
