Alejandro v. Geraldez

G.R. No. L-33849 · August 18, 1977 · Supreme Court

a. As to Taking Effect — Donations to be delivered after the donor's death · a. As to Taking Effect — Instances of donations *inter vivos*

Gist

A 1949 deed gave eight lots to the donors' children but said their "right and ownership" would be "fully effective" only when the donors died. The trial court called it a void mortis causa donation. The Supreme Court reversed: the habendum said the donors "wholeheartedly transfer and unconditionally give," the children accepted in the same deed, and the postponement touched only enjoyment. Naked title had passed in 1949.

Core Doctrine

Under Article 729, the deferment of delivery until the donor's death does not destroy the inter vivos character of a donation, provided the naked ownership is transmitted during the donor's lifetime. Where doubt remains, the conveyance should be deemed a donation inter vivos rather than mortis causa, in order to avoid uncertainty as to the ownership of the property subject of the deed.

Facts

On January 20, 1949, spouses Gabino Diaz and Severa Mendoza, with their children and a daughter-in-law, executed a deed of donation covering eight lots of the Lolomboy Friar Lands Estate, including the disputed Lot No. 2502.
The habendum and warranty clauses stated that the donors "wholeheartedly transfer and unconditionally give" the properties to the donees, while another clause provided that the donees' "right and ownership" would be "fully effective" only upon the donors' death. (The Court read the second clause as referring to beneficial ownership and the power to manage and enjoy — not to the vesting of naked title, which passed in 1949.)
The donees formally accepted the donation in the same instrument. An acceptance clause is a diagnostic mark of a donation inter vivos, since a mortis causa transfer, being a will, is never accepted during the donor's lifetime.
The deed prohibited the donees from selling the properties during the donors' lifetime except to defray the donors' expenses. A limitation on the right to sell presupposes that the donees already owned something to sell — the restraint proves the transfer rather than negating it.
Gabino Diaz died in 1962. On October 20, 1964, his widow Severa Mendoza executed a separate deed, expressly denominated a donation mortis causa, over her one-half share in Lot 2377-A in favour of her daughter Andrea Diaz; Severa died later that year.
On May 12, 1970, Andrea Diaz sued her brother Angel Diaz for partition of Lots 2377-A and 2502.
The heirs of Olimpia Diaz — the Alejandro intervenors — claimed a one-third interest in Lot 2502 on the ground that the 1949 donation was a void mortis causa disposition, so the lot should pass by intestate succession.
On June 30, 1971, the trial court ruled the 1949 deed a void donation mortis causa but nonetheless sustained the division of Lot 2502, recasting the deed as a valid extrajudicial partition under Article 1080. Both sides appealed, and the Supreme Court decided on August 18, 1977.

Issue

Whether the 1949 deed of donation — which provided that the "right and ownership" of the donees would be "fully effective" only upon the donors' death — is a donation inter vivos or mortis causa.

Secondary issue. Whether the trial court correctly characterised the 1949 deed as a valid extrajudicial partition under Article 1080.

Ruling

Main issue. INTER VIVOS. Under Article 729, if a donor intends a donation to take effect during his lifetime it is inter vivos even if delivery is deferred until after death; conversely, under Article 728, a donation made in contemplation of death, where ownership passes because of death, is mortis causa and must follow the formalities of a will. The 1949 deed transferred naked ownership on execution: the habendum and warranty clauses said the donors "wholeheartedly transfer and unconditionally give" the properties. The clause giving the donees "full power" only on the donors' death was read as referring to beneficial ownership — the right to manage and enjoy the fruits — and did not negate the immediate transfer of naked title. The donees' acceptance in the same instrument confirmed the character, Article 749 requiring acceptance for inter vivos donations while mortis causa transfers are never accepted during the donor's lifetime. And the limited right of disposition — no selling during the donors' lifetime except to defray their expenses — implies ownership had already passed, since there would be no need to limit a right the donees did not possess.

Secondary issue. NO. A valid partition under Article 1080 must cover the entire estate. Here only five of the eight lots were included, so the article was inapplicable.

The trial court's amended decision was REVERSED insofar as it pronounced the deed of donation void; the donation was declared valid as a donation inter vivos; the disputed lot was ordered partitioned in accordance with that deed between Andrea Diaz and Angel Diaz; the decision was AFFIRMED insofar as it did not require the Alejandro intervenors to pay attorney's fees. No costs.

"In case of doubt the conveyance should be deemed a donation inter vivos rather than mortis causa, in order to avoid uncertainty as to the ownership of the property subject of the deed."

Ratio

Codal test of effectivity. Under Article 729, a donation the donor intends to take effect during his lifetime is inter vivos even if delivery is deferred until after death. Under Article 728, one made in contemplation of death, where ownership passes because of death, is mortis causa and must follow the formalities of a will.
Transmission of naked ownership. The 1949 deed transferred nuda proprietas on execution: the habendum and warranty clauses stated that the donors "wholeheartedly transfer and unconditionally give" the properties — an immediate operative act rather than a post-mortem disposition.
Harmonising conflicting clauses. The clause giving the donees "full power" only on the donors' death was interpreted as referring to beneficial ownership (dominium utile), the right to manage and enjoy the fruits; it did not negate the immediate transfer of naked title.
Acceptance as a diagnostic marker. The donees formally accepted in the same instrument, and Article 749 requires acceptance for inter vivos donations, whereas mortis causa transfers are never accepted during the donor's lifetime.
Limited right of disposition. The deed barred the donees from selling during the donors' lifetime except to defray the donors' expenses. That limitation implies ownership had already passed — otherwise there would be no need to limit a right the donees did not possess.
Rejection of the Article 1080 theory. A valid partition under Article 1080 must cover the person's entire estate; only five of eight lots were included here.

Doctrine

The nature of the act, not its name: the designation of a donation as mortis causa or inter vivos is not controlling; the real intent is gathered from the body of the instrument and the surrounding circumstances.
Presumption of inter vivos: "In case of doubt the conveyance should be deemed a donation inter vivos rather than mortis causa, in order to avoid uncertainty as to the ownership of the property subject of the deed."
Crystallisation of Article 729: "When the donor intends that the donation shall take effect during the lifetime of the donor, though the property shall not be delivered till after the donor's death, this shall be a donation inter vivos."
Characteristics of mortis causa: a transfer is mortis causa if it (a) conveys no title before death; (b) is revocable ad nutum; and (c) is void if the donor survives the transferee.
A restraint on alienation presupposes ownership: limiting the donee's power to sell implies the donee has something to sell.

I. Gist and Central Doctrine

Relationship to requested topic: DIRECT.

This case involves a petition for review of a trial court decision in a partition case, where the central controversy centres on the characterisation of a 1949 deed of donation executed by spouses Gabino Diaz and Severa Mendoza in favour of their children. While the trial court declared the deed a void donation mortis causa for failure to comply with testamentary formalities, the Supreme Court reversed, declaring the instrument a valid donation inter vivos. The Court held that a donation is inter vivos when the donor intends it to take effect during their lifetime, even if material delivery of the property is deferred until after death. The single central doctrine is that under Article 729 of the Civil Code, the deferment of delivery until the donor's death does not destroy the inter vivos nature of a donation if the naked ownership is transmitted to the donee during the donor's lifetime.

II. Chronological Narration of Material Facts

On January 20, 1949, spouses Gabino Diaz and Severa Mendoza, along with their children and daughter-in-law, executed a deed of donation covering eight lots of the Lolomboy Friar Lands Estate, including the disputed Lot No. 2502.
In 1962, Gabino Diaz died.
On October 20, 1964, his widow Severa Mendoza executed a separate deed specifically denominated a donation mortis causa over her one-half share in Lot 2377-A (a portion of one of the original eight lots) in favour of her daughter, Andrea Diaz.
Later that same year, Severa Mendoza died.
On May 12, 1970, Andrea Diaz filed a suit for partition of Lots 2377-A and 2502 against her brother, Angel Diaz.
The heirs of Olimpia Diaz (the Alejandro intervenors) entered the case, claiming a one-third interest in Lot 2502 on the ground that the 1949 donation was a void mortis causa disposition, so the lot should be partitioned according to the laws of intestate succession.
On June 30, 1971, the trial court ruled that the 1949 deed was indeed a void donation mortis causa but nevertheless sustained the division of Lot 2502 between Angel and Andrea, characterising the deed as a valid extrajudicial partition under Article 1080.
Both parties appealed to the Supreme Court, which decided the case on August 18, 1977.

III. Arguments of the Parties

A. Alejandro Intervenors

The 1949 deed of donation is mortis causa because ownership of the properties did not pass to the donees during the donors' lifetime but was intended to be transmitted only upon death. Consequently, the donation is void for failure to comply with the formalities of a will, and the property must be distributed among the heirs pro indiviso as in an intestate estate.

B. Respondent (Andrea Diaz)

The 1949 deed is a valid donation inter vivos and should be given full effect according to its terms.

C. Common Ground

The execution of the 1949 deed and the subsequent deaths of the donors are undisputed in the record.

IV. Issues

A. MAIN ISSUE

Whether the 1949 deed of donation, which provided that the "right and ownership" of the donees would be "fully effective" only upon the death of the donors, is a donation inter vivos or mortis causa.

B. SECONDARY ISSUES

Whether the trial court correctly characterised the 1949 deed as a valid extrajudicial partition under Article 1080 of the Civil Code.

V. Ruling / Disposition

A. MAIN ISSUE

INTER VIVOS.

B. SECONDARY ISSUES

NO.

FALLO. "WHEREFORE, the trial court's amended decision is reversed insofar as it pronounces that the deed of donation is void. That donation is declared valid as a donation inter vivos. The disputed lot should be partitioned in accordance with that deed between Andrea Diaz and Angel Diaz. The decision is affirmed insofar as it does not require the Alejandro intervenors to pay attorney's fees to Andrea Diaz. No costs. SO ORDERED."

VI. Ratio Decidendi and Doctrines

A. Ratio Decidendi

The Court analysed the distinction between inter vivos and mortis causa donations, focusing on the time of effectivity and the transmission of ownership.
Codal test of effectivity. Under Article 729, if a donor intends a donation to take effect during their lifetime, it is inter vivos even if delivery is deferred until after death. Conversely, under Article 728, if the donation is made in contemplation of death and ownership passes only because of death, it is mortis causa and must follow the formalities of a will.
Transmission of naked ownership. The Court found that the 1949 deed transferred "naked ownership" (nuda proprietas) to the donees upon execution. The habendum and warranty clauses stated that the donors "wholeheartedly transfer and unconditionally give" the properties to the donees, indicating an immediate operative act rather than a post-mortem disposition.
Harmonising conflicting clauses. While a clause stated that the donees would have "full power" only upon the donors' death, the Court interpreted this as referring to beneficial ownership (dominium utile) — the right to manage and enjoy the fruits. It did not negate the immediate transfer of the naked title.
Acceptance as a diagnostic marker. The donees formally accepted the donation in the same instrument. The Court noted that Article 749 requires acceptance for inter vivos donations, whereas mortis causa transfers (wills) are never accepted during the donor's lifetime.
Limited right of disposition. The deed prohibited the donees from selling the properties during the donors' lifetime except to defray the donors' expenses. This limited right to dispose implies that ownership had already passed; otherwise there would be no need for a limitation on a right the donees did not possess.
Rejection of the Article 1080 partition. The Court rejected the trial court's fallback theory that the deed was a valid "partition inter vivos." A valid partition under that article must cover the entire estate of the person; here, only five of eight lots were included, making the article inapplicable.

B. Doctrines/Rules

The Nature of the Act vs. Its Name: The designation of a donation as mortis causa or inter vivos in the title is not controlling; the real intent is gathered from the body of the instrument and surrounding circumstances.
Presumption of Inter Vivos: "In case of doubt the conveyance should be deemed a donation inter vivos rather than mortis causa, in order to avoid uncertainty as to the ownership of the property subject of the deed."
Crystallisation of Article 729: "When the donor intends that the donation shall take effect during the lifetime of the donor, though the property shall not be delivered till after the donor's death, this shall be a donation inter vivos."
Characteristics of Mortis Causa: A transfer is mortis causa if: (a) it conveys no title before death; (b) it is revocable ad nutum; and (c) it is void if the donor survives the transferee. None of these were present here, the deed being intended to be irrevocable.

C. Limitations/Exceptions

The Court clarified that the fact a donation is given for "love and affection" or "past services" is not a definitive characteristic of inter vivos donations, as mortis causa transfers may be motivated by the same reasons. The dispositive element is the irrevocability of the transfer of title.

D. Topic Integration

This case is DIRECTLY controlling for "donations to be delivered after the donor's death," and equally for "instances of donations inter vivos."
It is the primary authority on Article 729, establishing that postponement of possession or delivery until after the donor's death does not alter the inter vivos character of the gift, provided the naked title was divested and accepted during the donor's lifetime.

VII. Separate Opinions

Antonio, J., concurring. He emphasises that the donation is inter vivos because the donor's intent was to produce a definitive effect upon execution. He notes that an inter vivos donation is a "gratuitous contract" requiring reciprocal consent and becoming perfect only upon acceptance, and underscores that once accepted, the donor can no longer unilaterally withdraw the offer except on specific legal grounds such as ingratitude or non-fulfilment of conditions.

(Fernando, J., Chairman, with Barredo, Concepcion, Jr. and Santos, JJ., concurring in the main opinion.)

Cited Laws & Provisions

Every statute, rule, and issuance the decision turns on — the text as written, and the work it does in this case.

Civil Code

Article 729, Civil Code

Civil Code of the Philippines (R.A. No. 386), Book III (Different Modes of Acquiring Ownership), Title III (Donation), Chapter 1 (Nature of Donations)

When the donor intends that the donation shall take effect during the lifetime of the donor, though the property shall not be delivered till after the donor's death, this shall be a donation inter vivos. The fruits of the property from the time of the acceptance of the donation, shall pertain to the donee, unless the donor provides otherwise. (n)

Why it is cited here

The article the case exists to apply, and the sentence to memorise verbatim:

"When the donor intends that the donation shall take effect during the lifetime of the donor, though the property shall not be delivered till after the donor's death, this shall be a donation inter vivos."

The clause after the comma is the whole point. Delivery may be postponed to death and the donation is still inter vivos — because what the law asks is not when the donee gets the thing but when the donation takes effect. Those are different dates, and conflating them is the mistake the trial court made.

What is transferred now is the nuda proprietas, the naked title. What is postponed is the dominium utile, the beneficial enjoyment. The 1949 deed said the donees' "right and ownership" would be "fully effective" only on the donors' death, and the Court read those words as referring to full power to manage and enjoy — not to the vesting of title.

The article's second sentence completes the picture: "the fruits of the property from the time of the acceptance of the donation, shall pass to the donee, unless the donor provides otherwise" — which is exactly how these deeds keep the fruits with the donor for life without keeping the title.

Civil Code

Article 728, Civil Code

Civil Code of the Philippines (R.A. No. 386), Book III (Different Modes of Acquiring Ownership), Title III (Donation), Chapter 1 (Nature of Donations)

Donations which are to take effect upon the death of the donor partake of the nature of testamentary provisions, and shall be governed by the rules established in the Title on Succession. (620)

Why it is cited here

The alternative the intervenors needed, and the three-part test that shows the deed was not it.

Donations "to take effect upon the death of the donor partake of the nature of testamentary provisions" and must follow the formalities of wills. Had the deed been of this kind it would have been void, since it was executed as a deed rather than as a will — and the lot would have passed by intestacy, giving the Alejandro intervenors their one-third.

The Court set out what a genuine mortis causa transfer looks like. It (a) conveys no title before death; (b) is revocable ad nutum — at the donor's pleasure; and (c) is void if the donor survives the transferee.

None fitted. The habendum said the donors "wholeheartedly transfer and unconditionally give" the properties; the deed was meant to be irrevocable; and nothing made it lapse if a child predeceased.

One trap the Court flags explicitly: a recital of "love and affection" or of past services is not decisive of an inter vivos character, because a mortis causa transfer may be moved by exactly the same feelings. The operative question is always irrevocability.

Civil Code

Article 749, Civil Code

Civil Code of the Philippines (R.A. No. 386), Book III (Different Modes of Acquiring Ownership), Title III (Donation), Chapter 2 (Persons Who May Give or Receive a Donation)

In order that the donation of an immovable may be valid, it must be made in a public document, specifying therein the property donated and the value of the charges which the donee must satisfy.

The acceptance may be made in the same deed of donation or in a separate public document, but it shall not take effect unless it is done during the lifetime of the donor.

If the acceptance is made in a separate instrument, the donor shall be notified thereof in an authentic form, and this step shall be noted in both instruments. (633)

Why it is cited here

The formality that doubles here as a diagnostic, which is the more interesting of its two roles.

The article requires that a donation of an immovable be in a public instrument and that the donee accept — in the same deed or a separate public instrument.

The donees accepted in the same 1949 instrument, and the Court used that structurally: an acceptance is required for inter vivos donations, whereas a mortis causa transfer, being a will, is never accepted during the donor's lifetime. A drafter who includes an acceptance clause has drafted something that operates now.

The second structural clue is subtler and worth carrying. The deed prohibited the donees from selling during the donors' lifetime, except to defray the donors' expenses. A restraint on alienation looks at first like the donors holding on — but the Court reads it the other way: there would be no need to limit a right the donees did not have. The prohibition presupposes that they already owned something to sell.

Gestopa v. Court of Appeals adopts this reasoning by name, and it recurs through the whole inter vivos line.

Civil Code

Article 1080, Civil Code

Civil Code of the Philippines (R.A. No. 386), Book III (Different Modes of Acquiring Ownership), Title IV (Succession), Chapter 4 (Provisions Common to Testate and Intestate Successions), Subsection 1 (Partition)

Should a person make partition of his estate by an act inter vivos, or by will, such partition shall be respected, insofar as it does not prejudice the legitime of the compulsory heirs.

A parent who, in the interest of his or her family, desires to keep any agricultural, industrial, or manufacturing enterprise intact, may avail himself of the right granted him in this article, by ordering that the legitime of the other children to whom the property is not assigned, be paid in cash. (1056a)

Why it is cited here

The trial court's fallback theory, and the reason it failed on a detail worth noticing.

"Should a person make a partition of his estate by an act inter vivos, or by will, such partition shall be respected, insofar as it does not prejudice the legitime of the compulsory heirs."

Having held the donation void, the trial court still upheld the division of Lot 2502 by recasting the 1949 deed as a valid partition inter vivos under this article. The Supreme Court rejected the recasting.

The reason is textual: a partition under Article 1080 must cover the person's estate — which the Court read as requiring the entire estate, not a selection from it. The 1949 deed covered only five of the eight lots, so it distributed part of the donors' holdings and left the rest untouched. That is a series of donations, not a partition.

The distinction matters beyond this case. A partition allocates an estate among heirs and operates within succession; a donation transfers particular property to particular donees and operates now. They are not interchangeable labels for the same act, and a deed that fails as one does not automatically survive as the other.

Facts

On January 20, 1949, spouses Gabino Diaz and Severa Mendoza, with their children and a daughter-in-law, executed a deed of donation covering eight lots of the Lolomboy Friar Lands Estate, including the disputed Lot No. 2502.
The habendum and warranty clauses stated that the donors "wholeheartedly transfer and unconditionally give" the properties to the donees, while another clause provided that the donees' "right and ownership" would be "fully effective" only upon the donors' death. (The Court read the second clause as referring to beneficial ownership and the power to manage and enjoy — not to the vesting of naked title, which passed in 1949.)
The donees formally accepted the donation in the same instrument. An acceptance clause is a diagnostic mark of a donation inter vivos, since a mortis causa transfer, being a will, is never accepted during the donor's lifetime.
The deed prohibited the donees from selling the properties during the donors' lifetime except to defray the donors' expenses. A limitation on the right to sell presupposes that the donees already owned something to sell — the restraint proves the transfer rather than negating it.
Gabino Diaz died in 1962. On October 20, 1964, his widow Severa Mendoza executed a separate deed, expressly denominated a donation mortis causa, over her one-half share in Lot 2377-A in favour of her daughter Andrea Diaz; Severa died later that year.
On May 12, 1970, Andrea Diaz sued her brother Angel Diaz for partition of Lots 2377-A and 2502.
The heirs of Olimpia Diaz — the Alejandro intervenors — claimed a one-third interest in Lot 2502 on the ground that the 1949 donation was a void mortis causa disposition, so the lot should pass by intestate succession.
On June 30, 1971, the trial court ruled the 1949 deed a void donation mortis causa but nonetheless sustained the division of Lot 2502, recasting the deed as a valid extrajudicial partition under Article 1080. Both sides appealed, and the Supreme Court decided on August 18, 1977.

Issue

Secondary issue. Whether the trial court correctly characterised the 1949 deed as a valid extrajudicial partition under Article 1080.

Ruling

Secondary issue. NO. A valid partition under Article 1080 must cover the entire estate. Here only five of the eight lots were included, so the article was inapplicable.

"In case of doubt the conveyance should be deemed a donation inter vivos rather than mortis causa, in order to avoid uncertainty as to the ownership of the property subject of the deed."

Ratio

Codal test of effectivity. Under Article 729, a donation the donor intends to take effect during his lifetime is inter vivos even if delivery is deferred until after death. Under Article 728, one made in contemplation of death, where ownership passes because of death, is mortis causa and must follow the formalities of a will.
Transmission of naked ownership. The 1949 deed transferred nuda proprietas on execution: the habendum and warranty clauses stated that the donors "wholeheartedly transfer and unconditionally give" the properties — an immediate operative act rather than a post-mortem disposition.
Harmonising conflicting clauses. The clause giving the donees "full power" only on the donors' death was interpreted as referring to beneficial ownership (dominium utile), the right to manage and enjoy the fruits; it did not negate the immediate transfer of naked title.
Acceptance as a diagnostic marker. The donees formally accepted in the same instrument, and Article 749 requires acceptance for inter vivos donations, whereas mortis causa transfers are never accepted during the donor's lifetime.
Limited right of disposition. The deed barred the donees from selling during the donors' lifetime except to defray the donors' expenses. That limitation implies ownership had already passed — otherwise there would be no need to limit a right the donees did not possess.
Rejection of the Article 1080 theory. A valid partition under Article 1080 must cover the person's entire estate; only five of eight lots were included here.

Doctrine

The nature of the act, not its name: the designation of a donation as mortis causa or inter vivos is not controlling; the real intent is gathered from the body of the instrument and the surrounding circumstances.
Presumption of inter vivos: "In case of doubt the conveyance should be deemed a donation inter vivos rather than mortis causa, in order to avoid uncertainty as to the ownership of the property subject of the deed."
Crystallisation of Article 729: "When the donor intends that the donation shall take effect during the lifetime of the donor, though the property shall not be delivered till after the donor's death, this shall be a donation inter vivos."
Characteristics of mortis causa: a transfer is mortis causa if it (a) conveys no title before death; (b) is revocable ad nutum; and (c) is void if the donor survives the transferee.

VI. Ratio Decidendi and Doctrines

A. Ratio Decidendi

The Court analysed the distinction between inter vivos and mortis causa donations, focusing on the time of effectivity and the transmission of ownership.
Codal test of effectivity. Under Article 729, if a donor intends a donation to take effect during their lifetime, it is inter vivos even if delivery is deferred until after death. Conversely, under Article 728, if the donation is made in contemplation of death and ownership passes only because of death, it is mortis causa and must follow the formalities of a will.
Transmission of naked ownership. The Court found that the 1949 deed transferred "naked ownership" (nuda proprietas) to the donees upon execution. The habendum and warranty clauses stated that the donors "wholeheartedly transfer and unconditionally give" the properties to the donees, indicating an immediate operative act rather than a post-mortem disposition.
Harmonising conflicting clauses. While a clause stated that the donees would have "full power" only upon the donors' death, the Court interpreted this as referring to beneficial ownership (dominium utile) — the right to manage and enjoy the fruits. It did not negate the immediate transfer of the naked title.
Acceptance as a diagnostic marker. The donees formally accepted the donation in the same instrument. The Court noted that Article 749 requires acceptance for inter vivos donations, whereas mortis causa transfers (wills) are never accepted during the donor's lifetime.
Limited right of disposition. The deed prohibited the donees from selling the properties during the donors' lifetime except to defray the donors' expenses. This limited right to dispose implies that ownership had already passed; otherwise there would be no need for a limitation on a right the donees did not possess.
Rejection of the Article 1080 partition. The Court rejected the trial court's fallback theory that the deed was a valid "partition inter vivos." A valid partition under that article must cover the entire estate of the person; here, only five of eight lots were included, making the article inapplicable.

B. Doctrines/Rules

The Nature of the Act vs. Its Name: The designation of a donation as mortis causa or inter vivos in the title is not controlling; the real intent is gathered from the body of the instrument and surrounding circumstances.
Presumption of Inter Vivos: "In case of doubt the conveyance should be deemed a donation inter vivos rather than mortis causa, in order to avoid uncertainty as to the ownership of the property subject of the deed."
Crystallisation of Article 729: "When the donor intends that the donation shall take effect during the lifetime of the donor, though the property shall not be delivered till after the donor's death, this shall be a donation inter vivos."
Characteristics of Mortis Causa: A transfer is mortis causa if: (a) it conveys no title before death; (b) it is revocable ad nutum; and (c) it is void if the donor survives the transferee. None of these were present here, the deed being intended to be irrevocable.

C. Limitations/Exceptions

The Court clarified that the fact a donation is given for "love and affection" or "past services" is not a definitive characteristic of inter vivos donations, as mortis causa transfers may be motivated by the same reasons. The dispositive element is the irrevocability of the transfer of title.

D. Topic Integration

This case is DIRECTLY controlling for "donations to be delivered after the donor's death," and equally for "instances of donations inter vivos."
It is the primary authority on Article 729, establishing that postponement of possession or delivery until after the donor's death does not alter the inter vivos character of the gift, provided the naked title was divested and accepted during the donor's lifetime.
