Rolando Santos v. Constancia Santos Alana

Summary

This case involves a property inheritance dispute between half-siblings over their father's sole asset - a 39-square meter lot in Manila. Gregorio Santos donated the entire property to his son Rolando through a valid deed of donation, but also executed an invalid deed of sale. When Gregorio died intestate, his daughter Constancia filed for partition, claiming the donation was inofficious as it deprived her of her legitime. The Supreme Court ruled that since the lot was Gregorio's only property and he made no reservation for his daughter's inheritance rights, the donation exceeded what he could legally give under Article 752 of the Civil Code. The Court ordered the property be divided equally between the siblings, with each receiving one-half as their respective legitime. The case established that inofficious donations can only be challenged after the donor's death when the estate's value can be determined, and such actions must be filed within ten years from the donor's death.
