G.R. No. L-6600 - Heirs of Bonsato vs. Court of Appeals

Petitioners, the heirs of Juan Bonsato and Felipe Bonsato, sought review of a decision by the Court of Appeals regarding two deeds of donation executed by the late Domingo Bonsato.
The deeds, executed on December 1, 1939, were in favor of his brother, Juan Bonsato, and his nephew, Felipe Bonsato, transferring several parcels of land in the municipalities of Mabini and Burgos, Pangasinan.
Respondents, including Josefa Utea and other heirs of Domingo Bonsato and his deceased wife Andrea Nacario, initiated the case alleging that the donations were executed under inducement and deception and that they were mortis causa—void for lacking the formalities required for a testamentary disposition.

The case was originally initiated in the Court of First Instance of Pangasinan (Case No. 8892) on June 7, 1945, with a complaint for annulment and damages.
On November 13, 1949, the trial court found that:

The donor executed the deeds while of sound mind and free from pressure or intimidation.
The donations were inter vivos in nature, not conditioned upon his death, despite the language indicating that they would “enter into vigor” after his death.
Since the donated properties were presumably conjugal (acquired during the coverture of Domingo Bonsato and Andrea Nacario), the donations affected only an undivided one-half interest of the properties.

The plaintiffs appealed, supporting the determination that the donations were inter vivos, while the respondents contended that the donations were mortis causa and void for non-observance of testamentary formalities.
The Court of Appeals, by a division of five:

A majority held that the donations were mortis causa and invalid because they did not comply with the formalities required for testaments.
A minority dissented, arguing the donations were inter vivos, thereby affirming the decision of the Court of First Instance.

Both deeds, although identical in form save for the names and property descriptions, contain key elements such as:

The explicit declaration of the donation as “perfect, irrevocable, and consummated”.
A provision stating that “after the death of the donor the aforesaid donation shall become effective,” implying full transfer of ownership free from encumbrances upon death.

Notably, there is an express absence of any reservation of title or revocability, aside from the donor’s reserved right over the fruits or produce of the property during his lifetime.

The central legal debate revolved around whether the donations were inter vivos (done during the donor’s lifetime) or donations mortis causa (conditional on the donor’s death).
Jurisprudence and doctrinal opinions, citing the Civil Code of 1889 (Art. 620) and subsequent commentaries by Mucius Scaevola, Manresa, and Castan, assert that:

Donations mortis causa have lost their independent legal existence and are treated as dispositions of property by will.
The essential characteristics of an inter vivos donation—irrevocability and immediate effectuation (apart from reserved benefits such as the right to enjoy the produce)—are manifest in the deeds at issue.

Whether the deeds of donation executed by Domingo Bonsato constitute valid inter vivos donations or if they are to be construed as donations mortis causa, thereby being void for failure to comply with the formalities of testamentary disposition.

Whether the inclusion of the clause indicating that the donation “enters into vigor” after the donor’s death implies a conditional, mortis causa character instead of an inter vivos donation.
Whether the failure to include a provision that allows the donor to revoke the donation supports the interpretation that the donation was intended to be irrevocable and fully operative during the donor’s lifetime.
The effect of the conjugal nature of the properties on the donations, specifically regarding the validity of partial donation (only affecting the non-conjugal half).
