Jose M. Cariño v. P. Fernando Ma. Abaya

Summary

Two elderly, unmarried sisters executed a document in 1921 distributing their properties among relatives, to take effect thirty days after both died. When Jose Cariño sought to be appointed administrator/trustee in 1935, the sisters' cousin Fernando Abaya challenged the document's validity. The Supreme Court ultimately held that the document constituted a donation mortis causa rather than an inter vivos donation, as evidenced by language indicating the distribution would occur after the grantors' deaths. Since such donations must comply with will formalities under Article 620 of the Civil Code, and this document lacked proper attestation and signatures required by law, it was void. The decision clarified the distinction between inter vivos and mortis causa donations and reinforced the requirement that testamentary dispositions must follow strict legal formalities to be valid.
