Facts

• On April 11, 1921, sisters Petrona Gray and Dorotea Gray executed a document in Ilocano, acknowledged before a Justice of the Peace, distributing their real and personal properties among various relatives and acquaintances.
• Its seventh clause stipulated that the properties were to be given to the assigned individuals "at the expiration of thirty days after the death of the last one to die between us," and the ninth clause referred to those "mentioned to inherit from us." (Postponed delivery plus the vocabulary of inheritance are the two markers the Court treated as decisive — to "inherit" is to acquire after a predecessor's death.)
• The deed lacked an attestation clause and marginal signatures on its pages. Being testamentary in substance, it had to meet the formalities of a will; those two omissions are what made it void rather than merely irregular.
• Petrona Gray died intestate and without descendants on January 28, 1926; Miguel Cariño — the person designated in the deed to deliver or administer the properties — died on February 12, 1927; and Dorotea Gray died intestate and without descendants on July 9, 1927.
• On February 16, 1935, Jose Cariño, petitioner and son of Miguel, petitioned the Court of First Instance of Ilocos Sur to be appointed administrator of the sisters' estate; on June 5, 1935 he amended his petition to pray instead that the properties be declared trust properties and that he be appointed trustee under the 1921 deed.
• On July 12, 1935, Father Fernando Ma. Abaya, a first cousin of the sisters, opposed, arguing the deed was null and void.
• The trial court held the properties to be trust properties; the Court of Appeals reversed, declaring the deed a void donation mortis causa; and the Supreme Court decided the review on June 26, 1940.

Issue

Ruling

"Donations which are to become effective upon the death of the donor partake of the nature of disposals of property by will [and] shall be governed by the rules established for testamentary successions."

Ratio

• Test of future effectivity. Clause 7 stated the properties shall be given "at the expiration of thirty days after the death of the last one to die," and the deed used future-tense verbs — "there shall be given to," "shall be administered" — showing a clear intent to defer transmission of ownership until after death, which places the deed under Article 728§ rather than Article 729§.
• The "inherit" marker. Clause 9 referred to those "mentioned to inherit from us." To inherit implies acquisition by heirs after the death of the predecessors — a "cogent reason" for concluding the grant was mortis causa.
• Formal requisites for validity. Being governed by the rules on succession, the deed had to follow the formalities of a will. It violated Section 618 of the Code of Civil Procedure for lack of an attestation clause and marginal signatures on its pages.
• Inefficacy of secondary facts. The Court rejected the argument that Miguel Cariño's administration of the properties proved an inter vivos transfer; the appellate court found the contention unsupported by evidence, and administration is in any event not ownership.
• Failure to plead prescription. The argument that the respondent's right to annul had prescribed was neither pleaded nor raised below, surfacing only on motion for reconsideration in the Court of Appeals.

Doctrine

1. Nature of post-mortem donations: "Donations which are to become effective upon the death of the donor partake of the nature of disposals of property by will [and] shall be governed by the rules established for testamentary successions."
2. Formalities as a condition of validity: a donation mortis causa "not executed in conformity with the provisions … for lack of attestation clause and marginal signatures" can be accorded no force or effect.
3. Presumption from language: terms implying future acquisition, and the word "inherit," are decisive markers of a mortis causa disposition.
4. Administration is not ownership: proof that a named administrator managed the property during the donors' lifetime does not convert a testamentary instrument into a present grant.

VI. Ratio Decidendi and Doctrines

A. Ratio Decidendi

• Test of future effectivity (Art. 728§ / old Art. 620). The Court scrutinised the language of the deed, specifically Clause 7, which stated the properties shall be given "at the expiration of thirty days after the death of the last one to die." This, combined with future-tense verbs like "there shall be given to" and "shall be administered," demonstrates a clear intent to defer the transmission of ownership until after death.
• The "inherit" marker. The Court noted that Clause 9 referred to those "mentioned to inherit from us." The term inherit implies the acquisition of property by heirs after the death of the predecessors, which the Court found to be a "cogent reason" for concluding the grant was mortis causa.
• Formal requisites for validity. Under Article 620 (now Art. 728§), donations mortis causa are governed by the rules on succession and must follow the formalities of a will. The deed violated Section 618 of the Code of Civil Procedure (now Articles 805 and 806) because it lacked an attestation clause and marginal signatures on its pages.
• Inefficacy of secondary facts. The Court rejected the petitioner's argument that Miguel Cariño's administration of the properties proved an inter vivos transfer, the Court of Appeals having found the contention unsupported by the evidence in a manner that would alter the deed's clear testamentary intent — and administration being, in any event, not ownership under Article 729§.
• Failure to plead prescription. The Court dismissed the argument that the respondent's right to annul the deed had prescribed, that defence being neither pleaded nor raised in the trial court and appearing for the first time only in a motion for reconsideration of the appellate decision.

B. Doctrines/Rules

1. Nature of Post-Mortem Donations: "Donations which are to become effective upon the death of the donor partake of the nature of disposals of property by will [and] shall be governed by the rules established for testamentary successions."
2. Formalities as a Condition for Validity: A donation mortis causa that is "not executed in conformity with the provisions … for lack of attestation clause and marginal signatures" cannot be accorded any force or effect.
3. Presumption from Language: The use of terms implying future acquisition, and the word "inherit," are decisive markers of a mortis causa disposition.

C. Limitations/Exceptions

• The Court distinguished the cases the petitioner relied on — Zapanta v. Posadas and Balaqui v. Dongso — as resting on different factual bases, so that even where a deed is styled a donation, the specific reservation of ownership until death remains the controlling factor.
• The prescription point was disposed of procedurally, not on its merits; the Court did not hold that no prescriptive period could ever apply.

D. Topic Integration

• This case is DIRECTLY illustrative of "instances of donations mortis causa." It is a foundational example of an instrument classified as mortis causa because of (a) the explicit postponement of delivery until after the donor's death, and (b) the use of testamentary terminology such as "inherit."
• It is an early definitive authority on the fatal consequences of failing to satisfy the formalities of a will where a donation is intended to take effect post mortem.
• Read with Maglasang (the predecease clause) and Sicad (withheld power of disposition), it completes the chapter's set of mortis causa markers by adding a third: the vocabulary of succession itself.
