Facts

• The property is Lot No. 1161 of the Cadastral Survey of Cebu, a corner lot of only about 45 square metres at F. Flores and Cavan Streets, Cebu City. The parties are co-owners pro indiviso — the plaintiffs to two-thirds, the defendants to one-third — and both sides had houses standing on it.
• The plaintiffs sued for partition, and by agreement the court appointed a commissioner, who surveyed the lot and in May 1976 recommended dividing it into 30 square metres for the plaintiffs and 15 for the defendants.
• The survey showed the defendants' house occupied 5 square metres of the portion allotted to the plaintiffs. The overlap appears only when the surveyor draws the line — nobody built across a boundary, because until the partition there was none to cross.
• Both sides conformed to the report and asked the court to settle who should take the disputed five square metres. The conformity mattered below: the trial court treated it as leaving the defendants "no other alternative except to remove and demolish."
• The trial court held Article 448 inapplicable between co-owners, citing Manresa, Sanchez Roman, Planiol and Ripert, and ordered the defendants to demolish the encroaching portion at their own expense within sixty days. It held that neither side could be made to pay the other anything.
• The defendants appealed, and the Court of Appeals certified the case here as a pure question of law — "the sole issue is the applicability of the provisions of Article 448... when the property involved is owned in common."

Issue

Ruling

"WHEREFORE, the decision appealed from is hereby MODIFIED by ordering plaintiff to indemnify defendants for the value of the[ ]portion of the house of defendants in accordance with Article 546 of the Civil Code, if plaintiffs elect to appropriate the same. Otherwise, the defendants shall pay the value of the 5 square meters of land occupied by their house at such price as may be agreed upon with plaintiffs and if its value exceeds the portion of the house that defendants built thereon, the defendants may choose not to buy the land but defendants must pay a reasonable rental for the use of the portion of the land of plaintiffs[ ]as may be agreed upon between the parties. In case of disagreement, the rate of rental shall be determined by the trial court. Otherwise, defendants may remove or demolish at their own expense the said portion of their house. No costs. SO ORDERED."

Ratio

• The general rule, and why it exists. "Article 448 of the Civil Code cannot apply where a co-owner builds, plants or sows on the land owned in common for then he did not build, plant or sow upon land that exclusively belongs to another but of which he is a co-owner. The co-owner is not a third person under the circumstances, and the situation is governed by the rules of co-ownership."§
• The exception, and its trigger. "However, when, as in this case, the co-ownership is terminated by the partition and it appears that the house of defendants overlaps or occupies a portion of 5 square meters of the land pertaining to plaintiffs which the defendants obviously built in good faith, then the provisions of Article 448 of the new Civil Code should apply."
• The authorities relied on for the exception. "Manresa and Navarro Amandi agree that the said provision of the Civil Code may apply even when there was co-ownership if good faith has been established."
• What follows once the article applies. "[T]he plaintiffs have the right to appropriate said portion of the house of defendants upon payment of indemnity to defendants as provided for in Article 546§... Otherwise, the plaintiffs may oblige the defendants to pay the price of the land occupied by their house."
• The ceiling on the second option. "However, if the price asked for is considerably much more than the value of the portion of the house of defendants built thereon, then the latter cannot be obliged to buy the land. The defendants shall then pay the reasonable rent... In case of disagreement, the trial court shall fix the terms thereof."
• Demolition survives only as the builder's own election. "Of course, defendants may demolish or remove the said portion of their house, at their own expense, if they so decide."

Doctrine

1. Article 448 Does Not Govern Between Co-Owners (Art. 448§): one who builds on the common property builds on land partly his own, is "not a third person," and is governed by the rules of co-ownership.
2. Partition Reopens Article 448: once the co-ownership is terminated and definite portions are allotted, an encroaching structure stands on land that now belongs exclusively to another.
3. Good Faith Is Judged When the Building Went Up: a co-owner who built while the land was still common "obviously built in good faith," there being no boundary to respect at the time.
4. The Landowner's Ordinary Election Then Applies: appropriate on indemnity under Article 546§, or oblige the builder to buy — subject to the ceiling where the land is worth considerably more.
5. Demolition Is the Builder's Option, Not the Landowner's Remedy: "defendants may demolish or remove the said portion of their house, at their own expense, if they so decide."

II. Chronological Narration of Material Facts

• The subject property is Lot No. 1161 of the Cadastral Survey of Cebu, "with an area of only about 45 square meters, situated at the corner of F. Flores and Cavan Streets, Cebu City covered by TCT No. 61850."
• Plaintiffs and defendants are co-owners pro indiviso, in the proportion of two-thirds to the plaintiffs and one-third to the defendants.
• Both parties had houses on the lot, which were later surveyed and shown on the commissioner's sketch plan.
• The plaintiffs filed an action for partition in the Court of First Instance of Cebu.
• The trial court appointed a commissioner in accordance with the agreement of the parties — Geodetic Engineer Espiritu Bunagan.
• On 29 May 1976 the commissioner conducted a survey, prepared a sketch plan and submitted his report, "recommending that the property be divided into two lots: Lot 1161-A with an area of 30 square meters for plaintiffs and Lot No. 1161-B with an area of 15 square meters for the defendants."
• The survey showed that "[t]he house of defendants occupied the portion with an area of 5 square meters of Lot 1161-A of plaintiffs."
• "The parties manifested their conformity to the report and asked the trial court to finally settle and adjudicate who among the parties should take possession of the 5 square meters of the land in question."
• The trial court ruled that neither side could be obliged to pay the other — "the plaintiffs cannot be obliged to pay for the value of the portion of the defendants' house which has encroached an area of five (5) sq. meters... The defendants cannot also be obliged to pay for the price of the said five (5) square meters" — because "[t]he rights of a builder in good faith under Article 448... do[ ] not apply to a case where one co-owner has built, planted or sown on the land owned in common." It cited Manresa, Sanchez Roman, Planiol and Ripert, and a Court of Appeals ruling that the article "cannot be invoked by one co-owner against another who builds, plants or sows upon their land, since the latter does not do so on land not belonging to him."
• Judgment assigned Lot 1161-A to the plaintiffs and ordered the defendants, at their expense, to remove and demolish the encroaching 5 square metres within sixty days and deliver possession. The commissioner's fee of ₱400.00 was apportioned — ₱133.33 to the defendants, the balance to the plaintiffs — and costs were divided two-thirds and one-third. A certified copy was to be recorded with the Register of Deeds of Cebu City.
• The defendants appealed, assigning two errors: the trial court's failure to apply the rights of a builder in good faith under Article 448, and its order to remove and demolish at their expense.
• The Court of Appeals certified the appeal to the Supreme Court "on account of the question of law involved," the sole issue being "the applicability of the provisions of Article 448 of the Civil Code relating to a builder in good faith when the property involved is owned in common."
• On 15 April 1988 the Supreme Court modified the judgment.

VI. Ratio Decidendi and Doctrines

A. Ratio Decidendi

• Why Article 448 normally has no place among co-owners. "[H]e did not build, plant or sow upon land that exclusively belongs to another but of which he is a co-owner. The co-owner is not a third person under the circumstances, and the situation is governed by the rules of co-ownership."§
• The commentators the trial court relied on. "Manresa agreeing with Sanchez Roman, says that as a general rule this article is not applicable because the matter should be governed more by the provisions on co-ownership than on accession. Planiol and Ripert are also of the opinion that this article is not applicable to a co-owner who constructs, plants or sows on the community property."
• The turning point. "However, when, as in this case, the co-ownership is terminated by the partition and it appears that the house of defendants overlaps or occupies a portion of 5 square meters of the land pertaining to plaintiffs which the defendants obviously built in good faith, then the provisions of Article 448 of the new Civil Code should apply."
• The authority for the exception. "Manresa and Navarro Amandi agree that the said provision of the Civil Code may apply even when there was co-ownership if good faith has been established."
• The consequences. "Applying the aforesaid provision of the Civil Code, the plaintiffs have the right to appropriate said portion of the house of defendants upon payment of indemnity to defendants as provided for in Article 546 of the Civil Code§. Otherwise, the plaintiffs may oblige the defendants to pay the price of the land occupied by their house."
• The disproportion ceiling. "However, if the price asked for is considerably much more than the value of the portion of the house of defendants built thereon, then the latter cannot be obliged to buy the land. The defendants shall then pay the reasonable rent to the plaintiff upon such terms and conditions that they may agree. In case of disagreement, the trial court shall fix the terms thereof."
• Demolition preserved as an election of the builder. "Of course, defendants may demolish or remove the said portion of their house, at their own expense, if they so decide."

B. Doctrines/Rules

1. Article 448 Presupposes Building on Another's Land, so it does not reach a co-owner building on the common property.
2. A Co-Owner Is Not a "Third Person" as against his fellow co-owners, and the rules of co-ownership govern instead.
3. Termination of the Co-Ownership by Partition Brings Article 448 Into Play, where a structure is then found to overlap another's allotted portion.
4. Good Faith Established at the Time of Building Carries Over — one who built when the land was still common "obviously built in good faith."
5. The Landowner's Election Applies as Usual: appropriate on Article 546§ indemnity, or oblige purchase, subject to the disproportion ceiling and a court-fixed rent.
6. Demolition Is the Builder's Own Option, at His Own Expense.

C. Limitations/Exceptions

• The exception is expressly tied to good faith having been established — "may apply even when there was co-ownership if good faith has been established." It is not automatic on every partition.
• The general rule survives intact for subsisting co-ownerships. A co-owner who builds today on undivided common land is still outside Article 448 and inside the rules of co-ownership.
• The Court did not disturb the partition itself, to which both sides had conformed; only the consequence for the five overlapping square metres was modified.
• The disposition leaves the values unfixed — indemnity, price and rent are all left to agreement, and to the trial court on disagreement. Compare Depra v. Dumlao, which spells out precisely what must be valued.
• Nothing here decides what happens if the encroaching co-owner is found in bad faith; for that, see Lumungo v. Usman, Mindanao Academy v. Yap and Santos v. Mojica.

D. Topic Integration

• The relationship is DIRECT.
• On the assigned subtopic — good faith under Article 448 — the case makes a distinction students routinely collapse. The question is not only "was the builder honest?" but "was he building on land belonging to another at all?" A co-owner fails the second question while the co-ownership lasts, and passes it the moment partition draws a line through the property.
• The mechanism is worth stating as a sequence: (1) co-owners build freely on common land, outside Article 448; (2) partition allots definite portions; (3) any structure now standing on another's portion is measured by Article 448; (4) good faith is assessed as of the time of building, when no boundary existed.
• It pairs naturally with Depra v. Dumlao (how the option is executed), with Macasaet v. Macasaet (good faith arising from a family arrangement rather than a mistaken belief in ownership), and with Nuguid v. Court of Appeals (the builder's right of retention pending indemnity).
• Note the practical warning for partition practice: a commissioner's plan that ignores existing structures creates the very encroachment it then has to resolve. Here the parties conformed to a sketch that ran the boundary through a standing house — and the litigation that followed was about nothing else.
