A man lost his Quezon City lot at a tax auction but kept ownership of the four-door apartment building he had put up on it. The buyers took out a writ of possession anyway, collected the tenants' rent for four years, and paid him for the building only at the end. The Supreme Court held that they had violated his right of retention and must hand over every peso of rent they collected in the meantime — ₱1,344,000, with interest.
Core Doctrine
Article 546 gives the builder in good faith full reimbursement for necessary and useful expenses and a right of retention until it is made. "The right of retention is considered as one of the measures devised by the law for the protection of builders in good faith. Its object is to guarantee full and prompt reimbursement as it permits the actual possessor to remain in possession while he has not been reimbursed." Consequently "a builder in good faith cannot be compelled to pay rentals during the period of retention nor be disturbed in his possession by ordering him to vacate," and the landowner may not offset the indemnity against the fruits — "the right to the expenses and the right to the fruits both pertain to the possessor, making compensation juridically impossible."

Gist
A man lost his Quezon City lot at a tax auction but kept ownership of the four-door apartment building he had put up on it. The buyers took out a writ of possession anyway, collected the tenants' rent for four years, and paid him for the building only at the end. The Supreme Court held that they had violated his right of retention and must hand over every peso of rent they collected in the meantime — ₱1,344,000, with interest.
Core Doctrine
Article 546 gives the builder in good faith full reimbursement for necessary and useful expenses and a right of retention until it is made. "The right of retention is considered as one of the measures devised by the law for the protection of builders in good faith. Its object is to guarantee full and prompt reimbursement as it permits the actual possessor to remain in possession while he has not been reimbursed." Consequently "a builder in good faith cannot be compelled to pay rentals during the period of retention nor be disturbed in his possession by ordering him to vacate," and the landowner may not offset the indemnity against the fruits — "the right to the expenses and the right to the fruits both pertain to the possessor, making compensation juridically impossible."
Facts
Pedro P. Pecson owned a 256-square-metre commercial lot at 27 Kamias Road, Quezon City, and built a four-door two-storey apartment building on it. He built on his own land — which is why Article 448 reaches this case only by analogy.
For unpaid realty taxes the lot was sold at auction and ended with spouses Juan and Erlinda Nuguid for ₱103,000. Pecson challenged the sale; the courts upheld their title but held with finality, on 23 June 1993, that the apartment building was not included.
The Nuguids moved for possession of both the lot and the building, and the trial court gave them a writ of possession on a reimbursement of only ₱53,000 in construction cost, ordered Pecson to pay them ₱21,000 a month, and allowed the ₱53,000 to be offset against rents he had collected. Pecson was dispossessed on 22 November 1993.Asking for a building they knew they had not bought is what the Court later treats as their election to appropriate — dating it to June 1993.
In 1995, in G.R. No. 115814, the Supreme Court set that order aside and remanded to fix the building's current market value, holding that Pecson "was entitled to retain ownership of the building and, necessarily, the income therefrom." Its dispositive said nothing about rent — the silence the Nuguids later read as a denial.
The parties agreed the building was worth ₱400,000. The Nuguids paid ₱300,000, and the ₱100,000 balance only in December 1997 — four years after taking possession, collecting the tenants' rent throughout. That gap is the case: possession taken before payment, income enjoyed the whole time.
In July 1998 the RTC ordered them to account for ₱1,344,000 — ₱28,000 a month for 48 months, the rate taken from the Nuguids' own affidavits. The Court of Appeals cut it to ₱280,000, counting only from the date the market value was fixed.
Issue
Whether a builder in good faith who was dispossessed before being paid is entitled to the income of the improvement for the whole period of dispossession — even though the earlier decision's dispositive portion said nothing about rentals.
Ruling
YES — the full ₱1,344,000 is restored.Article 448§ gives the landowner the option "either to appropriate the improvement as his own upon payment of the proper amount of indemnity or to sell the land to the possessor in good faith," and Article 546§ "provides that a builder in good faith is entitled to full reimbursement for all the necessary and useful expenses incurred; it also gives him right of retention until full reimbursement is made." That right is protective in purpose: "Its object is to guarantee full and prompt reimbursement as it permits the actual possessor to remain in possession while he has not been reimbursed." Three things follow. "[A] builder in good faith cannot be compelled to pay rentals during the period of retention nor be disturbed in his possession by ordering him to vacate." The landowner "is prohibited from offsetting or compensating the necessary and useful expenses with the fruits received by the builder-possessor in good faith," because "the right to the expenses and the right to the fruits both pertain to the possessor, making compensation juridically impossible." And retention carries the income with it — "[t]he right of retention, which entitles the builder in good faith to the possession as well as the income derived therefrom, is already provided for under Article 546," so the earlier dispositive "need not specifically include the income derived from the improvement" for Pecson to be entitled to it. Having elected to appropriate "as early as June 1993," the Nuguids "could not benefit from the lot's improvement, until they reimbursed the improver in full"; instead they "insisted on dispossessing Pecson," which "resulted in a violation of respondent's right of retention," and "took advantage of the situation to benefit from the highly valued, income-yielding, four-unit apartment building by collecting rentals thereon, before they paid for the cost." The builder having been "clearly denied his right of retention for almost half a decade," the trial court's award "was reasonable and equitable."
"WHEREFORE, the instant petition is DENIED for lack of merit. The Decision dated May 21, 2001 of the Court of Appeals in CA-G.R. CV No. 64295 is SET ASIDE and the Order dated July 31, 1998, of the Regional Trial Court, Branch 101, Quezon City, in Civil Case No. Q-41470 ordering the herein petitioners... to account for the rental income of the four-door two-storey apartment building from November 1993 until December 1997, in the amount of ₱1,344,000, computed on the basis of Twenty-eight Thousand (₱28,000.00) pesos monthly, for a period of 48 months, is hereby REINSTATED. Until fully paid, said amount of rentals should bear the legal rate of interest set at six percent (6%) per annum computed from the date of RTC judgment. If any portion thereof shall thereafter remain unpaid, despite notice of finality of this Court's judgment, said remaining unpaid amount shall bear the rate of interest set at twelve percent (12%) per annum... Costs against petitioners. SO ORDERED."
Ratio
What Article 546 gives."[A] builder in good faith is entitled to full reimbursement for all the necessary and useful expenses incurred; it also gives him right of retention until full reimbursement is made."§
Why retention exists. "The right of retention is considered as one of the measures devised by the law for the protection of builders in good faith. Its object is to guarantee full and prompt reimbursement as it permits the actual possessor to remain in possession while he has not been reimbursed (by the person who defeated him in the case for possession of the property) for those necessary expenses and useful improvements made by him on the thing possessed."
No rent, no eviction, during retention. "Accordingly, a builder in good faith cannot be compelled to pay rentals during the period of retention nor be disturbed in his possession by ordering him to vacate."
No offsetting against the fruits. "[T]he owner of the land is prohibited from offsetting or compensating the necessary and useful expenses with the fruits received by the builder-possessor in good faith. Otherwise, the security provided by law would be impaired. This is so because the right to the expenses and the right to the fruits both pertain to the possessor, making compensation juridically impossible; and one cannot be used to reduce the other."
Retention includes the income. "The right of retention, which entitles the builder in good faith to the possession as well as the income derived therefrom, is already provided for under Article 546 of the Civil Code," so the earlier decision's silence on rentals decides nothing.
The balance the law strikes. "While the law aims to concentrate in one person the ownership of the land and the improvements thereon in view of the impracticability of creating a state of forced co-ownership, it guards against unjust enrichment insofar as the good-faith builder's improvements are concerned."
The election, and when it was made."[S]ince petitioners opted to appropriate the improvement for themselves as early as June 1993, when they applied for a writ of execution despite knowledge that the auction sale did not include the apartment building, they could not benefit from the lot's improvement, until they reimbursed the improver in full, based on the current market value of the property."§
The violation, and its exploitation. "Despite the Court's recognition of Pecson's right of ownership over the apartment building, the petitioners still insisted on dispossessing Pecson by filing for a Writ of Possession to cover both the lot and the building. Clearly, this resulted in a violation of respondent's right of retention. Worse, petitioners took advantage of the situation to benefit from the highly valued, income-yielding, four-unit apartment building by collecting rentals thereon, before they paid for the cost of the apartment building."
How a dispositive is to be read. "The decision of May 26, 1995, should be construed in connection with the legal principles which form the basis of the decision, guided by the precept that judgments are to have a reasonable intendment to do justice and avoid wrong."
The award is equitable. "Given the circumstances of the instant case where the builder in good faith has been clearly denied his right of retention for almost half a decade, we find that the increased award of rentals by the RTC was reasonable and equitable. The petitioners had reaped all the benefits from the improvement introduced by the respondent during said period... They should account and pay for such benefits."
Article 448 by analogy. From the earlier decision: it "is not apposite to the case at bar where the owner of the land is the builder, sower, or planter who then later lost ownership of the land by sale, but may, however, be applied by analogy," and "the current market value of the improvements should be made as the basis of reimbursement."
Doctrine
The Builder in Good Faith Has a Right of Retention Until Full Reimbursement (Art. 546§) — a security device, whose object is "full and prompt reimbursement."
He May Not Be Made to Pay Rent During Retention, Nor Ordered to Vacate.
Retention Carries the Fruits: it entitles him "to the possession as well as the income derived therefrom," without need of an express award.
The Landowner May Not Offset the Indemnity Against the Fruits: both rights "pertain to the possessor, making compensation juridically impossible."
A Landowner Who Dispossesses Before Paying Must Account for the Income He Collected in the interim.
The Election to Appropriate Is Dated by Conduct — here, by applying for a writ of execution over a building the buyer knew he had not bought.
Indemnity Is the Current Market Value of the Improvement, not its historical construction cost.
Article 448 Applies by Analogy where the builder was the landowner who afterwards lost the land.
A Dispositive Portion Is Read With the Reasoning That Produced It, "guided by the precept that judgments are to have a reasonable intendment to do justice and avoid wrong."
How to place this case in the chapter. Nuguid is the builder's side of the machinery the rest of the group describes from the landowner's. Ochoa v. Apeta explains why the option belongs to the landowner; Depra v. Dumlao works out how he exercises it; Nuguid answers what the builder holds in the meantime — the property and its income, until he is paid in full. The sentence worth memorising is that retention exists "to guarantee full and prompt reimbursement," because every subsidiary rule follows from it: no rent during retention, no eviction, no set-off against the fruits. Note also the two smaller points that decide real cases. Indemnity is current market value, not construction cost — the difference here was ₱53,000 against ₱400,000. And a landowner elects by conduct: the Nuguids never filed a formal election, but moving for a writ over a building they knew was not theirs fixed their choice as of June 1993 and started the clock on what they owed.
Full Digest — Recitation Format
I. Gist and Central Doctrine
Relationship to requested topic: DIRECT.
Pedro P. Pecson built a four-door two-storey apartment building on his own 256-square-metre commercial lot at 27 Kamias Road, Quezon City. The lot was sold at a tax auction and ended with spouses Juan and Erlinda Nuguid, but the courts held with finality that the building was not included in the sale. The Nuguids nevertheless obtained a writ of possession over both, dispossessed Pecson on 22 November 1993, collected the tenants' rentals, and paid the agreed ₱400,000 value of the building only in December 1997. The RTC ordered them to account for ₱1,344,000 of rental income; the Court of Appeals cut it to ₱280,000; the Supreme Court restored the full amount with interest. The central doctrine is that Article 546§'s right of retention protects the builder in good faith by letting him hold the property and its income until fully reimbursed — so he "cannot be compelled to pay rentals during the period of retention nor be disturbed in his possession," and the indemnity may not be offset against the fruits.
II. Chronological Narration of Material Facts
Pedro P. Pecson owned a commercial lot at 27 Kamias Road, Quezon City, of 256 square metres, "on which he built a four-door two-storey apartment building."
"For failure to pay realty taxes, the lot was sold at public auction by the City Treasurer of Quezon City to Mamerto Nepomuceno, who in turn sold it for ₱103,000 to the spouses Juan and Erlinda Nuguid."
Pecson challenged the auction sale in Civil Case No. Q-41470, RTC of Quezon City, Branch 101. By decision of 8 February 1989 the RTC upheld the spouses' title but declared that the four-door two-storey apartment building was not included in the auction sale, affirmed in toto by the Court of Appeals and by the Supreme Court in G.R. No. 105360 on 25 May 1993.
On 23 June 1993, by entry of judgment in G.R. No. 105360, "the Nuguids became the uncontested owners of the 256-square meter commercial lot," and moved for delivery of possession of the lot and the apartment building.
On 15 November 1993, relying on Article 546, the trial court ruled that the Nuguids were to reimburse Pecson ₱53,000 in construction cost, that they were then "entitled to immediate issuance of a writ of possession over the lot and improvements," that Pecson pay them ₱21,000 monthly from 23 June 1993, and that the ₱53,000 be offset against rents Pecson had collected.
A writ of possession issued, and Pecson was dispossessed on 22 November 1993.
On 7 June 1994 the Court of Appeals (CA-G.R. SP No. 32679), relying on Article 448, affirmed the ₱53,000 award, held the possession issue moot because the writ had already been enforced, and ordered Pecson "to account for any and all fruits of the improvements received by him starting on June 23, 1993, with the amount of ₱53,000.00 to be offset therefrom."
On 26 May 1995, in G.R. No. 115814, the Supreme Court set aside both that decision and the 15 November 1993 order, and remanded for determination of the current market value of the apartment building, ruling that "[t]he value so determined shall be forthwith paid by the private respondents... otherwise the petitioner shall be restored to the possession of the apartment building until payment of the required indemnity." It held that Article 448 is not apposite but applies by analogy; that current market value is the basis of reimbursement; that "Pecson was entitled to retain ownership of the building and, necessarily, the income therefrom"; and that the appellate court erred in ordering him to account for rentals.
Pecson moved to restore possession and for an accounting; on 26 January 1996 the RTC denied restoration pending determination of the market value, and held the accounting motion in abeyance.
On 21 November 1996 the parties agreed the building was worth ₱400,000. Pecson had already received ₱300,000; by Order of 7 October 1997 the court directed payment of the ₱100,000 balance, which the Nuguids paid in December 1997.
The Nuguids then moved to close the case and cancel the notice of lis pendens, contending that Pecson's claim for rentals "was devoid of factual and legal bases."
On 31 July 1998 the RTC ordered them to pay ₱1,344,000 as reimbursement of Pecson's unrealised income "from November 22, 1993 up to December 1997" — 48 months at ₱28,000 a month, the figure taken from the Nuguids' own affidavits that three of the four units yielded ₱21,000, or ₱7,000 each. Reconsideration was denied.
On 21 May 2001 the Court of Appeals (CA-G.R. CV No. 64295) reduced the award to ₱280,000, representing rentals only "from the determination of the current market value on January 31, 1997 until its full payment on December 12, 1997," and denied reconsideration on 10 January 2002.
On 23 February 2005 the Supreme Court denied the petition and reinstated the ₱1,344,000 award, with interest.
III. Arguments of the Parties
A. Petitioners (Spouses Juan and Erlinda Nuguid)
A single assignment of error: that the Court of Appeals "erred in holding petitioners liable to pay rent over and above the current market value of the improvement when such was not provided for in the dispositive portion of the Supreme Court's ruling in G.R. No. 115814." Having paid ₱300,000 of the agreed ₱400,000, they argued that their failure to pay the balance "will, at most, entitle respondent to be restored to possession, but not to collect any rentals," that being the plain sense of "otherwise the petitioner shall be restored to the possession of the apartment building until payment of the required indemnity."
B. Respondent (Pedro P. Pecson)
That his claim was not an addition to the earlier judgment but its consequence: in moving for an accounting "all he asked was that the value of the fruits of the property during the period he was dispossessed be accounted for," the Court having held that "[t]he petitioner not having been so paid, he was entitled to retain ownership of the building and, necessarily, the income therefrom." The dispositive could not have specified rent "because its value had yet to be determined." He also faulted the appellate court for cutting the award and thereby defeating his right as a builder in good faith to income "from the period of his dispossession to full payment," a span of more than four years.
IV. Issues
A. MAIN ISSUE
Whether the petitioners must account for the rental income of the apartment building for the entire period from Pecson's dispossession until full payment of the indemnity, notwithstanding that the dispositive portion in G.R. No. 115814 did not mention rentals.
V. Ruling / Disposition
A. MAIN ISSUE
YES.Under Article 448 "the landowner is given the option, either to appropriate the improvement as his own upon payment of the proper amount of indemnity or to sell the land to the possessor in good faith"§; Article 546 "provides that a builder in good faith is entitled to full reimbursement for all the necessary and useful expenses incurred; it also gives him right of retention until full reimbursement is made"§. "[A] builder in good faith cannot be compelled to pay rentals during the period of retention nor be disturbed in his possession by ordering him to vacate," and the landowner "is prohibited from offsetting or compensating the necessary and useful expenses with the fruits received by the builder-possessor in good faith." "The right of retention, which entitles the builder in good faith to the possession as well as the income derived therefrom, is already provided for under Article 546," so the earlier dispositive "need not specifically include the income." The Nuguids having elected to appropriate "as early as June 1993," dispossessed Pecson in violation of that right, and collected rentals for four years before paying, "[t]hey should account and pay for such benefits."
"WHEREFORE, the instant petition is DENIED for lack of merit... the Order dated July 31, 1998... in the amount of ₱1,344,000, computed on the basis of Twenty-eight Thousand (₱28,000.00) pesos monthly, for a period of 48 months, is hereby REINSTATED. Until fully paid, said amount of rentals should bear the legal rate of interest set at six percent (6%) per annum computed from the date of RTC judgment. If any portion thereof shall thereafter remain unpaid, despite notice of finality of this Court's judgment, said remaining unpaid amount shall bear the rate of interest set at twelve percent (12%) per annum computed from the date of said notice. Costs against petitioners. SO ORDERED."
VI. Ratio Decidendi and Doctrines
A. Ratio Decidendi
The two articles, side by side."Under Article 448, the landowner is given the option, either to appropriate the improvement as his own upon payment of the proper amount of indemnity or to sell the land to the possessor in good faith."§"Relatedly, Article 546 provides that a builder in good faith is entitled to full reimbursement for all the necessary and useful expenses incurred; it also gives him right of retention until full reimbursement is made."§
The policy. "While the law aims to concentrate in one person the ownership of the land and the improvements thereon in view of the impracticability of creating a state of forced co-ownership, it guards against unjust enrichment insofar as the good-faith builder's improvements are concerned."
Retention as a protective device. "The right of retention is considered as one of the measures devised by the law for the protection of builders in good faith. Its object is to guarantee full and prompt reimbursement as it permits the actual possessor to remain in possession while he has not been reimbursed (by the person who defeated him in the case for possession of the property) for those necessary expenses and useful improvements made by him on the thing possessed."
Its immediate consequences. "Accordingly, a builder in good faith cannot be compelled to pay rentals during the period of retention nor be disturbed in his possession by ordering him to vacate."
And the bar on set-off. "In addition, as in this case, the owner of the land is prohibited from offsetting or compensating the necessary and useful expenses with the fruits received by the builder-possessor in good faith. Otherwise, the security provided by law would be impaired. This is so because the right to the expenses and the right to the fruits both pertain to the possessor, making compensation juridically impossible; and one cannot be used to reduce the other."
The election, dated by conduct. "[S]ince petitioners opted to appropriate the improvement for themselves as early as June 1993, when they applied for a writ of execution despite knowledge that the auction sale did not include the apartment building, they could not benefit from the lot's improvement, until they reimbursed the improver in full, based on the current market value of the property."
The violation. "Despite the Court's recognition of Pecson's right of ownership over the apartment building, the petitioners still insisted on dispossessing Pecson by filing for a Writ of Possession to cover both the lot and the building. Clearly, this resulted in a violation of respondent's right of retention."
The aggravation. "Worse, petitioners took advantage of the situation to benefit from the highly valued, income-yielding, four-unit apartment building by collecting rentals thereon, before they paid for the cost of the apartment building. It was only four years later that they finally paid its full value to the respondent."
How to read the earlier dispositive. "Petitioners' interpretation of our holding in G.R. No. 115814 has neither factual nor legal basis. The decision of May 26, 1995, should be construed in connection with the legal principles which form the basis of the decision, guided by the precept that judgments are to have a reasonable intendment to do justice and avoid wrong."
The silence explained. "[T]he dispositive portion of our decision in G.R. No. 115814 need not specifically include the income derived from the improvement in order to entitle him, as a builder in good faith, to such income. The right of retention, which entitles the builder in good faith to the possession as well as the income derived therefrom, is already provided for under Article 546 of the Civil Code."
The measure of the award. "Given the circumstances of the instant case where the builder in good faith has been clearly denied his right of retention for almost half a decade, we find that the increased award of rentals by the RTC was reasonable and equitable."
B. Doctrines/Rules
Full Reimbursement Plus Retention (Art. 546§), the latter a device "to guarantee full and prompt reimbursement."
No Rent and No Eviction During Retention.
Retention Extends to the Fruits, without need of an express award.
No Compensation Between Indemnity and Fruits — both pertain to the possessor.
A Landowner Who Dispossesses Before Paying Must Account for the Income Received.
The Election to Appropriate May Be Shown by Conduct and is dated from it.
Indemnity Is Current Market Value, not construction cost.
Article 448§ Applies by Analogy where the builder later lost the land he built on.
A Dispositive Is Construed With the Reasoning Behind It.
C. Limitations/Exceptions
The Court proceeded by analogy, the builder here being the original landowner. Article 448 is "not apposite" to that situation on its own terms.
The rental figure was not independently proved by Pecson — it rests on the Nuguids' own affidavits that three units earned ₱21,000. The case is therefore weak authority on how to prove rental value.
The award is expressly grounded in equity on these facts, the builder having been "clearly denied his right of retention for almost half a decade."
The 12% interest on amounts unpaid after notice of finality reflects the rule then in force; the legal rate was later revised by BSP Circular No. 799 (2013).
Nothing here allows a builder to retain indefinitely: retention lasts only until full reimbursement, and the landowner ends it by paying.
D. Topic Integration
The relationship is DIRECT.
On the assigned subtopic — the builder's right to retain — the case gives both the rule and its rationale. Retention is security, and it is what converts the builder's claim from a lawsuit into leverage: he keeps the thing until he is paid.
Learn the three consequences as a set, because they are how the right is usually tested: (1) no rent may be charged during retention; (2) he may not be ordered to vacate; (3) the indemnity may not be set off against the fruits, "compensation" being "juridically impossible" where both rights belong to the same person.
The fourth consequence is the one this case adds to the chapter: retention includes the income. A landowner who takes possession early does not merely delay payment — he appropriates fruits that are not his, and must hand them back.
Read it with Ochoa v. Apeta (why the option belongs to the landowner) and Depra v. Dumlao (how the option is exercised, and the builder's parallel right of retention there). Together the three describe one machine from three angles.
A practical warning worth keeping: the Nuguids' loss was self-inflicted. Had they paid the ₱400,000 in 1993, they would have owed nothing further. By taking possession first and paying last, they collected ₱1,344,000 in rent that was never theirs — and had to return it with interest.
VII. Separate Opinions
NOT IN RECORD. The decision was penned by Justice Leonardo A. Quisumbing for the First Division, with Chief Justice Davide, Jr. (Chairman) and Justices Ynares-Santiago, Carpio and Azcuna concurring.

Every statute, rule, and issuance the decision turns on — the text as written, and the work it does in this case.
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 article the case is assigned for. "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."
Three consequences the Court draws from those words, and they are the case.
Retention is a security device, not a courtesy. "The right of retention is considered as one of the measures devised by the law for the protection of builders in good faith. Its object is to guarantee full and prompt reimbursement as it permits the actual possessor to remain in possession while he has not been reimbursed... for those necessary expenses and useful improvements made by him on the thing possessed." Take away the possession and the security is gone.
The retaining builder owes no rent and cannot be evicted. "[A] builder in good faith cannot be compelled to pay rentals during the period of retention nor be disturbed in his possession by ordering him to vacate."
The indemnity cannot be set off against the fruits. "[T]he owner of the land is prohibited from offsetting or compensating the necessary and useful expenses with the fruits received by the builder-possessor in good faith. Otherwise, the security provided by law would be impaired. This is so because the right to the expenses and the right to the fruits both pertain to the possessor, making compensation juridically impossible; and one cannot be used to reduce the other."
That last point is the one most often missed. Retention carries the income too: "[t]he right of retention, which entitles the builder in good faith to the possession as well as the income derived therefrom, is already provided for under Article 546" — which is why the earlier judgment did not need to mention rent for the builder to be entitled to it.
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 article that gives the landowner the election, applied here by analogy. It normally addresses one who builds on land belonging to another, whereas Pecson built on his own lot and lost it afterwards at a tax auction — so in the earlier decision the Court held that "Article 448... is not apposite to the case at bar where the owner of the land is the builder, sower, or planter who then later lost ownership of the land by sale, but may, however, be applied by analogy."
Once applied, its ordinary consequences follow: "the landowner is given the option, either to appropriate the improvement as his own upon payment of the proper amount of indemnity or to sell the land to the possessor in good faith." The Nuguids elected to appropriate — and the Court dates that election precisely, to when "they applied for a writ of execution despite knowledge that the auction sale did not include the apartment building."
Two riders matter for the analogy. The indemnity is measured by "the current market value of the improvements," not by historical construction cost — which is why the ₱53,000 figure the trial court first used was set aside in favour of the ₱400,000 the parties eventually agreed on. And the policy the article serves is stated plainly: the law "aims to concentrate in one person the ownership of the land and the improvements thereon in view of the impracticability of creating a state of forced co-ownership," while guarding "against unjust enrichment insofar as the good-faith builder's improvements are concerned."
