G.R. No. 27939 - Solis vs. Barroso

The donors, spouses Juan Lambino and Maria A. Barroso, executed a donation propter nuptias on June 2, 1919, through a private document (Exhibit A).
The donation was made in favor of their son, Alejo Lambino, and Fortunata Solis in connection with the imminent marriage of Alejo Lambino and Fortunata Solis.
A condition was attached specifying that, in case of the donees, one-half of the donated lands would revert to the donor while the surviving donee would retain the other half.

On June 8, 1919, Alejo Lambino and Fortunata Solis were married, and immediately thereafter, the donors delivered the possession of the donated lands to them.
On August 3, 1919, Alejo Lambino died, and in the same year, donor Juan Lambino also passed away.
After the death of Juan Lambino, his wife, Maxima Barroso, subsequently recovered possession of the donated lands.

The surviving donee, Fortunata Solis, commenced an action against the surviving donor, Maxima Barroso, and the heirs of the deceased donor (Eugenia and Marciana Lambino, along with their respective husbands).
Fortunata Solis sought the execution of the proper deed of donation to transfer, according to law, one-half of the donated property to her, along with the partitioning of the property and its fruits.

Whether a donation propter nuptias executed in a private document satisfies the formal requirement for the transfer of real property.
Whether the lack of execution in a public instrument—as required by article 633 of the Civil Code—renders the donation void.

Whether article 1279 of the Civil Code, which governs contracts and their formalities, can be applied to a donation propter nuptias.
Whether the classification of the donation as onerous (as argued by the lower court) is appropriate, thereby justifying the application of contract rules (specifically article 622).

Whether the marriage, serving as a resolutory condition in the donation, should be considered as a valuable consideration necessarily creating an obligation.
How the legal effects of the donation are determined in light of it being predicated on marriage, and if non-compliance with formal requisites affects its validity.

The relevance and applicability of the decision in Torres de Villanueva vs. Standard Oil Co. of New York (34 Phil. 370) to the present donation case.
Whether the prior jurisprudence addressing a different context (arras) can influence the determination of the donation’s validity.
