Title

Quijada v. Court of Appeals

Case Decision Date

G.R. No. 126444 December 4, 1998

Trinidad Quijada donated two hectares to a municipality for a provincial high school, with an automatic reversion clause if the school never came. She then sold the same land while the municipality still owned it. Years later the school failed and the land reverted to her heirs. The Court upheld the sale: the reversion vested title in the heirs, and Article 1434 passed that after-acquired title straight through to the buyer.

Core Doctrine

A donation inter vivos on condition that the donee build a structure is subject to a resolutory condition: ownership passes to the donee immediately on the donor's knowledge of acceptance, subject only to reversion if the condition fails. Meanwhile the donor keeps an inchoate interest — and under Article 1434, when the seller later acquires the title he lacked at the time of sale, that title passes by operation of law to the buyer.

Quijada v. Court of Appeals

G.R. No. 126444 · December 4, 1998 · Supreme Court

a. As to Taking Effect — Effect of resolutory conditions on donations *inter vivos* (Art. 731)

Gist

Trinidad Quijada donated two hectares to a municipality for a provincial high school, with an automatic reversion clause if the school never came. She then sold the same land while the municipality still owned it. Years later the school failed and the land reverted to her heirs. The Court upheld the sale: the reversion vested title in the heirs, and Article 1434 passed that after-acquired title straight through to the buyer.

Core Doctrine

A donation inter vivos on condition that the donee build a structure is subject to a resolutory condition: ownership passes to the donee immediately on the donor's knowledge of acceptance, subject only to reversion if the condition fails. Meanwhile the donor keeps an inchoate interest — and under Article 1434, when the seller later acquires the title he lacked at the time of sale, that title passes by operation of law to the buyer.

Facts

  • On April 5, 1956, Trinidad Quijada and her siblings executed a conditional deed of donation over a two-hectare parcel in favour of the Municipality of Talacogon, stipulating that the land be used "solely and exclusively" as a campus for a proposed provincial high school, and providing that should the school be discontinued or closed the property would revert to the donors. (The automatic reversion clause is what later made judicial revocation unnecessary — without it the donor would have had to sue under Article 764.)
  • Despite the donation, Trinidad remained in physical possession of the land.
  • On July 29, 1962, Trinidad sold one hectare of the lot to respondent Regalado Mondejar, and later sold him the remaining hectare by verbal agreement and receipts of payment; Mondejar in turn sold portions to the other respondents. At that date the Municipality was the owner, so Trinidad was selling land that was not hers — the defect Article 1434 would eventually cure.
  • In 1980, after Trinidad's death, her heirs filed a complaint for forcible entry against Mondejar, which was dismissed for failure to prosecute.
  • In 1987, the Sangguniang Bayan of Talacogon enacted a resolution reverting the land to the donors, the proposed high school having failed to materialise. This is the operative date: the condition failed, the reversion clause bit, and title returned to Trinidad's heirs — instantly passing through to Mondejar under the after-acquired-title rule.
  • On July 5, 1988, Trinidad's heirs sued for quieting of title and recovery of possession, alleging the 1962–1968 sales were void because the Municipality owned the land at the time.
  • The trial court held the sales void; the Court of Appeals reversed, holding that Trinidad retained an inchoate interest that validated the sale upon reversion; and the Supreme Court decided on December 4, 1998.

Issue

Whether the condition to build a school on the donated land is a suspensive or a resolutory condition, and what the effect of its non-fulfilment is on a sale made by the donor during the period the donee held ownership.
Secondary issue. Whether the petitioners' action to quiet title is barred by laches.

Ruling

Main issue. It is a RESOLUTORY CONDITION. Under Article 734§ a donation is perfected the moment the donor knows of the donee's acceptance, and under Article 712§ donation is a mode of acquiring and transmitting ownership — so on the Municipality's acceptance in 1956 it became the owner. Following Central Philippine University v. Court of Appeals, a condition to build a school is resolutory, not suspensive: "it is not correct to say that the schoolhouse had to be constructed before the donation became effective … otherwise, it would be invading the property rights of the donor." The donee must own the land first to have the legal right to construct on it. Ownership therefore passed at present but remained subject to total extinguishment on non-fulfilment, and during that interval the donor retained an "inchoate interest." When the school failed and the automatic reversion clause operated in 1987, ownership returned to Trinidad's heirs — and under Article 1434§, "when a person who is not the owner of a thing sells or alienates and delivers it, and later the seller or grantor acquires title thereto, such title passes by operation of law to the buyer or grantee." The title the heirs acquired in 1987 therefore passed automatically to Mondejar, and the sales stand.
Secondary issue. NO. The petitioners' cause of action commenced only in 1987, when the property reverted; filing suit in 1988 was no unreasonable delay.
The decision of the respondent court was AFFIRMED, with no pronouncement as to costs.
"So long as the resolutory condition subsists and is capable of fulfillment, the donation remains effective and the donee continues to be the owner."

Ratio

  • Perfection and transfer of title. Under Article 734§ a donation is perfected the moment the donor knows of the acceptance; under Article 712§ donation is a mode of acquiring and transmitting ownership. On acceptance in 1956, the Municipality became the owner.
  • Resolutory nature of building conditions. Applying the test of Central Philippine University, a condition to build a school is resolutory: the donee must own the land first to have the legal right to construct the building, so it cannot be a condition precedent.
  • The precarity of the donee's title. Because the condition was resolutory, ownership passed to the Municipality at present but was subject to total extinguishment on non-fulfilment; during that period the donor retained an "inchoate interest" — a potential right to the land should it revert, per Article 1181§.
  • Validation of the sale. Trinidad had no title to convey in 1962, but the later fulfilment of the resolutory condition triggered the automatic reversion clause and ownership returned to her heirs in 1987.
  • After-acquired title. Under Article 1434§, that title passed by operation of law to Mondejar the moment the heirs acquired it.
  • Laches. Inapplicable: the cause of action arose only in 1987, and suit was filed in 1988.

Doctrine

  1. Resolutory condition test: "When the donation is subject to the condition that the donee should construct or build a structure on the donated property, the donation is subject to a resolutory condition."
  2. Subsisting effectiveness (Art. 731§): "So long as the resolutory condition subsists and is capable of fulfillment, the donation remains effective and the donee continues to be the owner."
  3. Automatic reversion: where a deed provides for automatic reversion on breach, the property reverts without need of a separate document the moment non-compliance is established.
  4. Exception to nemo dat (Art. 1434§): a seller's subsequent acquisition of title validates a prior sale by operation of law.
  5. The donor's inchoate interest: during the pendency of a resolutory condition the donor holds a potential right to the land — not ownership, but the seed of an after-acquired title.

Full Digest — Recitation Format

I. Gist and Central Doctrine

Relationship to requested topic: DIRECT.
This case involves a petition for review of a Court of Appeals decision in an action for quieting of title and recovery of possession filed by the heirs of a donor against a buyer who purchased the property after it had been conditionally donated to a municipality. The primary controversy lies in the nature of the condition imposed in the deed of donation — the construction of a provincial high school — and how its eventual non-fulfilment affected a sale executed by the donor prior to the land's reversion. The Supreme Court affirmed the appellate court's ruling that the sale was valid, characterising the donation as one subject to a resolutory condition. The central doctrine is that under Article 731§ and Article 1181 of the Civil Code§, a donation inter vivos made on the condition that the donee construct a structure on the land is subject to a resolutory condition, meaning ownership is transmitted immediately to the donee upon the donor's knowledge of acceptance, subject only to reversion should the condition fail.

II. Chronological Narration of Material Facts

  • On April 5, 1956, Trinidad Quijada, along with her siblings, executed a conditional deed of donation over a two-hectare parcel of land in favour of the Municipality of Talacogon.
  • The deed stipulated that the land be used "solely and exclusively" as a campus for a proposed provincial high school, and included an automatic reversion clause providing that should the school be discontinued or closed, the property would revert to the donors.
  • Despite the donation, Trinidad remained in physical possession of the land.
  • On July 29, 1962, Trinidad sold one hectare of the subject lot to respondent Regalado Mondejar.
  • Subsequently, through a verbal agreement and receipts of payment, she sold the remaining one hectare to Mondejar, who then sold portions of the land to other respondents.
  • In 1980, following Trinidad's death, her heirs filed a complaint for forcible entry against Mondejar, but the case was dismissed for failure to prosecute.
  • In 1987, the Sangguniang Bayan of Talacogon enacted a resolution reverting the land to the donors because the proposed high school failed to materialise.
  • On July 5, 1988, Trinidad's heirs (petitioners) filed an action for quieting of title and recovery of possession, alleging that the 1962–1968 sales to Mondejar were void as the Municipality owned the land at that time.
  • The trial court ruled the sales void, but the Court of Appeals reversed, holding that Trinidad retained an inchoate interest that validated the sale upon the land's reversion. The Supreme Court decided on December 4, 1998.

III. Arguments of the Parties

A. Petitioners (Heirs of Trinidad Quijada)

The sales made by Trinidad Quijada to Mondejar between 1962 and 1968 were null and void because, at the time of the transaction, ownership had already been transferred to the Municipality of Talacogon by virtue of the 1956 donation. Since Trinidad was no longer the owner, she had no legal title or right to dispose of the property.

B. Respondents (Regalado Mondejar, et al.)

The sales were valid and they were buyers in good faith. They further argued that the petitioners' action was barred by laches or prescription.

C. Common Ground

The execution of the 1956 donation, the subsequent sales to Mondejar, and the 1987 resolution of the Sangguniang Bayan reverting the land are undisputed.

IV. Issues

A. MAIN ISSUE

Whether the condition to build a school on the donated land is a suspensive condition or a resolutory condition, and what the effect of its non-fulfilment is on a sale made by the donor during the period the donee held ownership.

B. SECONDARY ISSUES

Whether the petitioners' action to quiet title is barred by laches.

V. Ruling / Disposition

A. MAIN ISSUE

RESOLUTORY CONDITION.

B. SECONDARY ISSUES

NO.
FALLO. "WHEREFORE, the decision of the respondent court is hereby AFFIRMED. No pronouncement as to costs. SO ORDERED."

VI. Ratio Decidendi and Doctrines

A. Ratio Decidendi

  • Perfection and transfer of title (Art. 734§ / Art. 712§). Under Article 734, a donation is perfected the moment the donor knows of the acceptance by the donee. Under Article 712, donation is a mode of acquiring and transmitting ownership. Thus, once the Municipality accepted the donation in 1956, it became the owner of the property.
  • Resolutory nature of building conditions. The Court applied the test from Central Philippine University v. CA, ruling that a condition to build a school is a resolutory condition, not a suspensive one. It reasoned that "it is not correct to say that the schoolhouse had to be constructed before the donation became effective … otherwise, it would be invading the property rights of the donor." The donee must own the land first to have the legal right to construct the building.
  • The "precarity" of title. Because the condition was resolutory, ownership passed to the Municipality at present but was subject to total extinguishment upon non-fulfilment. During this period, the donor retained an "inchoate interest" in the property — a potential right to the land should it revert.
  • Validation of the sale (Art. 1434§). While Trinidad did not have the title to convey when she sold the land to Mondejar in 1962, the subsequent fulfilment of the resolutory condition — the failure to build the school — triggered the automatic reversion clause. Upon the Municipality's manifestation that it could not comply, ownership reverted to Trinidad's heirs.
  • Passing of title by operation of law. Applying Article 1434, the Court ruled that "when a person who is not the owner of a thing sells or alienates and delivers it, and later the seller or grantor acquires title thereto, such title passes by operation of law to the buyer or grantee." Consequently, the moment the land reverted to the heirs in 1987, the title they acquired automatically passed to Mondejar.
  • Laches analysis. The Court found laches inapplicable because the petitioners' cause of action only commenced in 1987 when the property reverted; filing suit in 1988 was not an unreasonable delay.

B. Doctrines/Rules

  1. Resolutory Condition Test: "When the donation is subject to the condition that the donee should construct or build a structure on the donated property, the donation is subject to a resolutory condition."
  2. Subsisting Effectiveness (Art. 731§): "So long as the resolutory condition subsists and is capable of fulfillment, the donation remains effective and the donee continues to be the owner."
  3. Automatic Reversion: If a deed provides for automatic reversion upon breach of a resolutory condition, the property reverts to the donor without need of a separate document or obligation on the donor's part the moment non-compliance is established.
  4. Nemo dat exception via Article 1434§: While one cannot generally give what one does not have, a subsequent acquisition of title by a seller who previously sold the property without title validates the prior sale by operation of law.

C. Limitations/Exceptions

  • The Court noted that had the donor not included an automatic reversion clause, judicial intervention might have been required under Article 764§ to revoke the donation.
  • The donee remains the owner so long as it tries to comply within a reasonable period — though this becomes irrelevant once the donee formally manifests an inability to comply.

D. Topic Integration

  • This case is DIRECTLY illustrative of the "effect of resolutory conditions on donations inter vivos." It clarifies that such conditions do not suspend the transfer of title; they allow a present, effective transfer that remains subject to total loss.
  • It is the primary authority for the rule that title validated post-reversion through Article 1434§ protects third-party buyers even where the initial sale occurred during the donee's period of ownership.
  • Read with Central Philippine University, the two cases divide the ground: CPU answers what happens between donor and donee when the condition fails, and Quijada answers what happens to a third-party buyer caught in the interval.

Why it is cited here

The article the syllabus assigns this case to, and the sentence that keeps the donee an owner while the condition is still open.

"When a person donates something, subject to the resolutory condition of the donor's survival, there is a donation inter vivos."

The wider principle the Court draws from it is the one to remember: "So long as the resolutory condition subsists and is capable of fulfillment, the donation remains effective and the donee continues to be the owner."

That is what makes a resolutory condition so different from a suspensive one. Nothing is held back pending the condition. The donee is a full owner from perfection, and the condition operates only as a mechanism that can later undo what has already vested.

For this case that produced a precise timeline: the Municipality of Talacogon owned the two hectares from 1956, still owned them when Trinidad sold in 1962, and lost them only in 1987 when the school failed and the reversion clause bit.

Civil Code

Article 712, Civil Code

Civil Code of the Philippines (R.A. No. 386), Book III (Different Modes of Acquiring Ownership)

Ownership is acquired by occupation and by intellectual creation.

Ownership and other real rights over property are acquired and transmitted by law, by donation, by testate and intestate succession, and in consequence of certain contracts, by tradition.

They may also be acquired by means of prescription. (609a)

Why it is cited here

The article that made the Municipality an owner rather than a mere holder, and it is the premise the petitioners were right about.

Ownership is "acquired and transmitted by succession, and in consequence of certain contracts, by tradition." Donation is a mode: it transfers ownership directly rather than merely creating an obligation to transfer.

So when the Municipality accepted in 1956, it did not receive a promise or a licence — it became the owner of the two hectares. That is why Trinidad genuinely had nothing to sell in 1962, and why the heirs' argument was correct as far as it went.

Where they went wrong was in the next step. A mode can transfer a defeasible ownership, and this one did: the Municipality owned the land subject to a resolutory condition, and when that condition failed the ownership was extinguished and returned. Article 712 tells you that ownership moved; it does not tell you it moved permanently.

Civil Code

Article 1181, Civil Code

Civil Code of the Philippines (R.A. No. 386), Book IV (Obligations and Contracts), Title I (Obligations), Chapter 3 (Different Kinds of Obligations), Section 1 (Pure and Conditional Obligations)

In conditional obligations, the acquisition of rights, as well as the extinguishment or loss of those already acquired, shall depend upon the happening of the event which constitutes the condition. (1114)

Why it is cited here

The general law of conditional obligations, supplying the vocabulary and the test.

"In conditional obligations, the acquisition of rights, as well as the extinguishment or loss of those already acquired, shall depend upon the happening of the event which constitutes the condition."

Following Central Philippine University v. Court of Appeals — decided three years earlier — the Court applied the ownership-before-construction test: "it is not correct to say that the schoolhouse had to be constructed before the donation became effective … otherwise, it would be invading the property rights of the donor." A donee cannot lawfully build on land he does not own, so ownership must pass first, and the condition can only be resolutory.

What Quijada adds to CPU is the position of the donor during the interval. Because the transfer is defeasible, Trinidad retained an "inchoate interest" — a potential right to the land should it come back. Not ownership, and not enough to convey; but not nothing either, and it is the seed from which Article 1434 later grows a valid sale.

Civil Code

Article 764, Civil Code

Civil Code of the Philippines (R.A. No. 386), Book III (Different Modes of Acquiring Ownership), Title III (Donation), Chapter 4 (Revocation and Reduction of Donations)

The donation shall be revoked at the instance of the donor, when the donee fails to comply with any of the conditions which the former imposed upon the latter.

In this case, the property donated shall be returned to the donor, the alienations made by the donee and the mortgages imposed thereon by him being void, with the limitations established, with regard to third persons, by the Mortgage Law and the Land Registration laws.

This action shall prescribe after four years from the noncompliance with the condition, may be transmitted to the heirs of the donor, and may be exercised against the donee's heirs. (647a)

Why it is cited here

The route the donor did not have to take, and the reason the automatic reversion clause mattered so much to the buyer.

The article lets a donor sue to revoke where the donee fails to comply with an imposed condition, within four years of the non-compliance.

Note what that means in practice: revocation under this article is a judicial remedy. The donor must go to court, and the property comes back only on a judgment.

The 1956 deed avoided all of it by carrying its own reversion clause — should the school be discontinued or closed, the land reverts. So when the Sangguniang Bayan resolved in 1987 that the school had failed, the property came back without any court action at all, and the moment it did, Article 1434 carried the title through to Mondejar.

The Court said as much: had the donor not included the clause, "judicial intervention might have been required under Article 764." Whether a deed carries an automatic reversion clause therefore decides not only how the donor recovers, but when — and, as here, whose hands the land ends up in.

Civil Code

Article 1434, Civil Code

Civil Code of the Philippines (R.A. No. 386), Book IV (Obligations and Contracts), Title IV (Estoppel (N))

When a person who is not the owner of a thing sells or alienates and delivers it, and later the seller or grantor acquires title thereto, such title passes by operation of law to the buyer or grantee.

Why it is cited here

The provision that saved a sale which was, when made, a sale of another's land.

"When a person who is not the owner of a thing sells or alienates and delivers it, and later the seller or grantor acquires title thereto, such title passes by operation of law to the buyer or grantee."

This is the after-acquired title rule, and it is a genuine qualification of nemo dat quod non habet. Trinidad had nothing to sell in 1962; the Municipality owned the land. Ordinarily that ends the matter and the buyer takes nothing.

But in 1987 the school failed, the automatic reversion clause operated, and the land came back to Trinidad's heirs. At that instant the title they acquired passed straight through to Mondejar by force of this article — no new deed, no fresh act of conveyance, no need for anyone's cooperation.

The lesson is that a sale by a non-owner is not automatically void forever; it is ineffective until cured, and this article is one way it can be cured. It also explains the laches holding: the heirs' cause of action arose only in 1987, so suing in 1988 was prompt.

Civil Code

Article 734, 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)

The donation is perfected from the moment the donor knows of the acceptance by the donee. (623)

Why it is cited here

Where the Municipality's ownership came from, and the reason the petitioners' theory was right in principle and still lost.

"The donation is perfected from the moment the donor knows of the acceptance by the donee."

Read with Article 712, which makes donation a mode of acquiring ownership, perfection in 1956 made the Municipality the owner outright.

So the heirs were correct that Trinidad had no title in 1962 — that is exactly what the Court held. Their error was in supposing the consequence was permanent nullity. The sale was ineffective at the time, and Article 1434 made it good the moment the land returned.

Note the interaction with automatic reversion. Because the deed carried its own reversion clause, no court action was needed to revoke: the property came back the moment non-compliance was established. Without such a clause the donor would have had to seek judicial revocation under Article 764, and the whole timeline — and the buyer's fate — would have been different.

Where the Municipality's ownership came from, and the reason the petitioners' theory was right in principle and still lost.

"The donation is perfected from the moment the donor knows of the acceptance by the donee."

Read with Article 712, which makes donation a mode of acquiring ownership, perfection in 1956 made the Municipality the owner outright.

So the heirs were correct that Trinidad had no title in 1962 — that is exactly what the Court held. Their error was in supposing the consequence was permanent nullity. The sale was ineffective at the time, and Article 1434 made it good the moment the land returned.

Note the interaction with automatic reversion. Because the deed carried its own reversion clause, no court action was needed to revoke: the property came back the moment non-compliance was established. Without such a clause the donor would have had to seek judicial revocation under Article 764, and the whole timeline — and the buyer's fate — would have been different.
