Title

Sarmiento v. Agana

Case Decision Date

G.R. No. 57288 April 30, 1984

The case involves a dispute between a new landowner and a couple who constructed a residential house on a lot after being told by the wife's mother that they could build there. The land actually belonged to third parties who sold it to the petitioner, leading to an ejectment suit. The Supreme Court affirmed the lower court's finding that the builders acted in good faith and that the landowner is bound by the preclusive options of the Civil Code.

Core Doctrine

The central doctrine is that a builder is in good faith under Article 448 when they construct a building under an honest belief of ownership or right, such as when they rely on the permission of a person they reasonably believe has the power to grant such right; consequently, the landowner cannot refuse both to pay for the building and to sell the land to the builder to compel the latter to remove the improvements.

b. Right of Accession — Builder in good faith (Art. 448): good faith

Gist

The case involves a dispute between a new landowner and a couple who constructed a residential house on a lot after being told by the wife's mother that they could build there. The land actually belonged to third parties who sold it to the petitioner, leading to an ejectment suit. The Supreme Court affirmed the lower court's finding that the builders acted in good faith and that the landowner is bound by the preclusive options of the Civil Code.

Core Doctrine

The central doctrine is that a builder is in good faith under Article 448 when they construct a building under an honest belief of ownership or right, such as when they rely on the permission of a person they reasonably believe has the power to grant such right; consequently, the landowner cannot refuse both to pay for the building and to sell the land to the builder to compel the latter to remove the improvements.

Facts

  • While respondent Ernesto was courting his future wife, his mother-in-law informed them they could construct a residential house on Lot D of a subdivision in Parañaque.
  • Relying on this representation and reasonably expecting to eventually be given the land, Ernesto constructed a residential house on the property (later valued between ₱30,000 to ₱40,000).
  • It was subsequently discovered that the land was not owned by the mother-in-law but was registered to Spouses Santos.
  • Spouses Santos sold the subject lot to petitioner Sarmiento, who thereafter demanded that Ernesto and his wife vacate the premises.
  • Sarmiento filed an ejectment suit against Ernesto in the Municipal Trial Court (MTC).
  • The MTC found Ernesto to be a builder in good faith and ordered Sarmiento to pay ₱20,000 for the house before the respondents were required to vacate.
  • The Regional Trial Court (RTC) modified the decision, ruling that under Article 448§, Sarmiento must exercise a choice within 60 days: (1) appropriate the house by paying ₱40,000, or (2) oblige Ernesto to buy the land for ₱25,000.
  • Sarmiento refused to exercise either option and instead sought to compel the removal of the house.
  • The RTC allowed Ernesto to deposit ₱25,000 with the court as the purchase price for the land, which Sarmiento challenged via certiorari.
  • The Supreme Court issued its final decision on April 30, 1984, affirming the RTC.

Issue

Whether a person who builds a house on the land of another with the permission of a party§ they mistakenly believed to be the owner qualifies as a "builder in good faith" under Article 448§ of the Civil Code.
Secondary issues. Whether a landowner can refuse to exercise both options provided under Article 448§ and instead compel the builder in good faith to remove the improvements.

Ruling

Main issue. YES — he built in good faith. Good faith is "honesty of intention" and "freedom from knowledge of circumstances which ought to put the holder upon inquiry," and Ernesto built on the strength of his mother-in-law's permission — someone who could "reasonably be expected to later on give them the land." That reliance is an honest belief in his right to build, which is what industrial accession requires; Article 448 therefore governs even though the land was another's.
Secondary issues. NO — the landowner may not refuse both options. The law gives him a preclusive choice — appropriate the building on paying the indemnity under Article 546, or oblige the builder to pay the price of the land — but "he cannot... refuse both to pay for the building and to sell the land and compel the owner of the building to remove it from the land where it is erected." Meanwhile the builder is "entitled to retain the possession of the land until he is paid the value of his building." Because Sarmiento refused to pay the ₱40,000 value of the house and refused to sell the lot, the trial court rightly let Ernesto pay the land's ₱25,000 value and end the impasse.
"The owner of the building erected in good faith on a land owned by another, is entitled to retain the possession of the land until he is paid the value of his building, under article 453 (now Article 546§). The owner, of the land, upon, the other hand, has the option, under article 361 (now Article 448§), either to pay for the building or to sell his land to the owner of the building. But he cannot... refuse both to pay for the building and to sell the land and compel the owner of the building to remove it from the land where it is erected."

Ratio

  • The Court’s reasoning is anchored on the definition of Good Faith as an intangible quality involving "honesty of intention" and "freedom from knowledge of circumstances which ought to put the holder upon inquiry."
  • The Court ruled that Ernesto was in good faith because he relied on the permission of his mother-in-law, who could "reasonably be expected to later on give them the land."
  • This reliance established an honest belief in his right to build, satisfying the requirements of industrial accession.
  • Applying Article 448§, the Court held that a conflict of rights arises between the landowner and the builder in good faith.
  • To resolve this, the law grants the landowner a preclusive choice: (1) to appropriate the improvements after paying indemnity under Article 546§ (necessary and useful expenses), or (2) to oblige the builder to pay the price of the land.
  • The Court emphasized that the landowner "cannot refuse both" options.
  • Because the petitioner refused to pay the ₱40,000 value of the house and refused to sell the land, the RTC correctly allowed the builder to pay the land's value (₱25,000) to terminate the conflict.
  • The right to demand removal (demolition) exists only if the landowner chooses to sell the land and the builder "fails to pay for the same."

Doctrine

  1. Definition of Good Faith (Art. 526§): Identified by the belief that the land is owned or that—by some title—one has the right to build, plant, or sow thereon.
  2. Special Application of Art. 448§: The provision applies to builders who rely on the consent of another whom they mistakenly believed to be the owner.
  3. Preclusive Options of Landowner: The owner of the land is authorized to exercise the option because their right is older and based on the principle that the accessory follows the principal.
  4. Prohibition of Forced Removal: A landowner cannot bypass the options in Art. 448§ and compel removal of a structure built in good faith unless the builder refuses to pay for the land after that option is chosen.
  5. Right of Retention (Art. 546§): A builder in good faith is entitled to retain possession of the land until they are reimbursed for the value of their building.
The builder cannot be obliged to buy the land if its value is "considerably more" than that of the building; in such a case, the builder shall pay reasonable rent.

  • The Supreme Court issued its final decision on April 30, 1984, affirming the RTC.

III. Arguments of the Parties

A. Petitioner (Sarmiento)

The petitioner argued that she was the lawful owner of the land by virtue of a deed of sale and that the respondents had no right to occupy her property. She effectively sought the removal of the structure without complying with the indemnity requirements of Article 448§, refusing to choose between appropriation or sale.

B. Respondent (Ernesto)

The respondents maintained that they were builders in good faith because they constructed the house with the express permission of the person they believed to be the owner. They argued they were entitled to the protections of Articles 448§ and 546, specifically the right to be indemnified for the value of the house or to purchase the land at its fair market value.

IV. Issues

A. MAIN ISSUE

Whether a person who builds a house on the land of another with the permission of a party they mistakenly believed to be the owner qualifies as a "builder in good faith" under Article 448§ of the Civil Code.

B. SECONDARY ISSUES

Whether a landowner can refuse to exercise both options provided under Article 448§ and instead compel the builder in good faith to remove the improvements.

V. Ruling / Disposition

A. MAIN ISSUE

YES — he built in good faith. Good faith is "honesty of intention" and "freedom from knowledge of circumstances which ought to put the holder upon inquiry," and Ernesto built on the strength of his mother-in-law's permission — someone who could "reasonably be expected to later on give them the land." That reliance is an honest belief in his right to build, which is what industrial accession requires; Article 448 therefore governs even though the land was another's.

B. SECONDARY ISSUES

NO — the landowner may not refuse both options. The law gives him a preclusive choice — appropriate the building on paying the indemnity under Article 546, or oblige the builder to pay the price of the land — but "he cannot... refuse both to pay for the building and to sell the land and compel the owner of the building to remove it from the land where it is erected." Meanwhile the builder is "entitled to retain the possession of the land until he is paid the value of his building." Because Sarmiento refused to pay the ₱40,000 value of the house and refused to sell the lot, the trial court rightly let Ernesto pay the land's ₱25,000 value and end the impasse.
"The owner of the building erected in good faith on a land owned by another, is entitled to retain the possession of the land until he is paid the value of his building, under article 453 (now Article 546§). The owner, of the land, upon, the other hand, has the option, under article 361 (now Article 448§), either to pay for the building or to sell his land to the owner of the building. But he cannot... refuse both to pay for the building and to sell the land and compel the owner of the building to remove it from the land where it is erected."

  • In such a case, the builder shall pay reasonable rent.

D. Topic Integration

  • The relationship is DIRECT.
  • This case is the leading authority for the subtopic "Good Faith" under Article 448§.
  • It illustrates that good faith is a concept of the mind determined by outward acts.
  • It teaches that the jus vindicandi (right to recover) of a landowner under Article 428 is restricted by the equity of a builder who acted without malice, ensuring that the recovery of real property does not result in the unjust destruction of useful improvements.

Civil Code

Article 448, Civil Code

Civil Code of the Philippines (R.A. No. 386), Book II (Property, Ownership, and Its Modifications), Title II (Ownership), Chapter 2 (Right of Accession), Section 2 (Right of Accession With Respect to Immovable Property)

The owner of the land on which anything has been built, sown or planted in good faith, shall have the right to appropriate as his own the works, sowing or planting, after payment of the indemnity provided for in articles 546 and 548, or to oblige the one who built or planted to pay the price of the land, and the one who sowed, the proper rent. However, the builder or planter cannot be obliged to buy the land if its value is considerably more than that of the building or trees. In such case, he shall pay reasonable rent, if the owner of the land does not choose to appropriate the building or trees after proper indemnity. The parties shall agree upon the terms of the lease and in case of disagreement, the court shall fix the terms thereof. (361a)

Why it is cited here

The regime the builder qualified for, and this case is the generous end of the good-faith enquiry.

Once inside Article 448, the landowner must choose: appropriate the building on paying the indemnity, or oblige the builder to buy the land. The choice is the owner's — but the article's proviso protects the builder where the land is worth considerably more than the building, in which case he pays reasonable rent instead, on terms the court fixes if the parties disagree.

That proviso is what makes the outcome workable when a substantial house sits on modest land, or the reverse. The article is engineered to end the split between land and improvement without ruining either party.

Civil Code

Article 526, Civil Code

Civil Code of the Philippines (R.A. No. 386), Book II (Property, Ownership, and Its Modifications), Title V (Possession), Chapter 1 (Possession and the Kinds Thereof)

He is deemed a possessor in good faith who is not aware that there exists in his title or mode of acquisition any flaw which invalidates it.

He is deemed a possessor in bad faith who possesses in any case contrary to the foregoing.

Mistake upon a doubtful or difficult question of law may be the basis of good faith. (433a)

Why it is cited here

The definition, applied here to a builder who knew perfectly well she did not own the land.

Good faith is ignorance of "any flaw in his title or mode of acquisition" — and the phrase "mode of acquisition" is doing the work. A builder need not believe she owns the land; it is enough that she believes by some title she has a right to build on it.

So one who builds on the strength of permission from a person she reasonably believes has the power to grant it — a parent, an apparent owner — builds in good faith. Her belief is about the authority of the person who allowed her, and she is unaware of the flaw in it.

Set that against J.M. Tuason, where presumptive knowledge of a Torrens title destroyed good faith. The difference is what a reasonable person could check. A register is publicly searchable and everyone is charged with it; another person's authority often cannot be verified at all, so a reasonable belief in it survives.

The third paragraph reinforces the result — "mistake upon a doubtful or difficult question of law may be the basis of good faith" — since the extent of a family member's authority over family land is exactly such a question.

Civil Code

Article 546, Civil Code

Civil Code of the Philippines (R.A. No. 386), Book II (Property, Ownership, and Its Modifications), Title V (Possession), Chapter 3 (Effects of Possession)

Necessary expenses shall be refunded to every possessor; but only the possessor in good faith may retain the thing until he has been reimbursed therefor.

Useful expenses shall be refunded only to the possessor in good faith with the same right of retention, the person who has defeated him in the possession having the option of refunding the amount of the expenses or of paying the increase in value which the thing may have acquired by reason thereof. (453a)

Why it is cited here

The indemnity the finding unlocks, and the right of retention is the practical prize.

Necessary expenses are refunded to every possessor, with retention only for the good-faith one; useful expenses only to the possessor in good faith, the owner choosing between refunding the cost and paying the increase in value.

Because she built in good faith, she may remain in possession until indemnified. The landowner exercising the Article 448 option must pay first and take the land afterwards — which, where the building is a family home, is very often the whole practical outcome of the case.
