A house, wall, warehouse, or other structure built on the wrong parcel does not automatically become removable without compensation. Philippine law protects a person who honestly believed that the land was theirs—or that they had a valid right to build on it—while also preserving the landowner’s superior rights. The result usually depends on three questions: Was the builder in good faith? Did the landowner know and object? What option does the landowner choose under Article 448 of the Civil Code?

What Is a Builder in Good Faith?

A builder in good faith is a person who constructs a building or improvement on land belonging to another while honestly believing that:

They own the land;
They acquired the land through a valid title or transaction; or
They have a legitimate claim of ownership or legal right to build there.

The builder must also be unaware of any defect in the title, deed, inheritance, sale, survey, or other basis of possession.

Under Articles 526 and 527 of the Civil Code of the Philippines, good faith is generally presumed. The person alleging bad faith carries the burden of proving it. However, this presumption can be defeated by evidence showing that the builder knew the land belonged to someone else or knew that their supposed title was defective. (Lawphil)

The Supreme Court commonly describes a builder in good faith as someone who builds in the belief that the land is theirs and without knowledge of any flaw in the title or mode of acquisition.

Examples of possible good faith

A person may qualify as a builder in good faith when:

A relocation survey later reveals that part of a house accidentally crossed the boundary line;
A buyer constructed a home based on a deed of sale later declared defective;
An heir built on land reasonably believed to be included in the inherited property;
A person purchased land together with an existing structure and did not know that the structure encroached on an adjoining lot;
The landowner knowingly allowed permanent construction without objecting, depending on the circumstances.

Situations that usually do not qualify

Article 448 generally does not protect someone who:

Knew from the beginning that another person owned the land;
Built despite a written objection, demand, court case, or clear boundary marker;
Occupied the property only as a tenant, caretaker, agent, usufructuary, or borrower;
Was merely tolerated by the owner and understood that the permission could be withdrawn;
Built under a lease, contract to sell, or other agreement that separately governs the improvements;
Continued major construction after learning of the encroachment.

Good faith is a factual issue. Courts examine deeds, titles, surveys, permits, correspondence, family arrangements, witness testimony, and the conduct of both parties before and after construction.

Legal Basis: Articles 448, 546, and 548 of the Civil Code

Article 448 of the Civil Code governs buildings, plantings, and sowing made in good faith on another person’s land. It gives the landowner two principal options:

Appropriate or keep the improvement after paying the proper indemnity; or
Require the builder to purchase the land occupied by the improvement.

The choice belongs to the landowner, not the builder. However, the landowner cannot simply refuse both options and immediately require demolition when the builder is legally recognized as being in good faith.

In Depra v. Dumlao, the Supreme Court explained that Article 448 avoids forced co-ownership between the landowner and the owner of the building. The landowner must make the statutory choice because the land is considered the principal property and the improvement is the accessory. (Lawphil)

Article 546: Necessary and useful expenses

Article 546 distinguishes two important types of expenses:

Necessary expenses are those required to preserve the property or prevent its deterioration.
Useful expenses are those that increase the property’s value, productivity, utility, or usefulness.

Necessary expenses must generally be reimbursed to every possessor. Useful expenses are reimbursable only to a possessor in good faith.

For useful expenses, the person recovering the property may generally choose between:

Refunding the amount of the useful expenses; or
Paying the increase in value caused by the improvement.

A builder in good faith also has a right of retention, meaning the builder may ordinarily remain in possession of the affected premises until the required reimbursement is paid. (Lawphil)

Article 548: Luxury or ornamental expenses

Expenses made purely for luxury, decoration, or pleasure are generally not reimbursable. The builder may remove ornamental items if removal will not injure the principal property, unless the succeeding possessor chooses to keep them and pays the amount required by law.

Items such as detachable chandeliers, decorative panels, removable fixtures, or ornamental structures may fall into this category. A permanent foundation, retaining wall, septic system, or structural extension is more likely to be examined as a necessary or useful improvement.

Rights of a Builder in Good Faith

1. The right to require the landowner to make a choice

The builder cannot personally choose to buy the land and force the owner to sell immediately. The builder may, however, ask the court to require the landowner to exercise one of the options under Article 448.

As the Supreme Court stated in Depra v. Dumlao and later cases, the landowner may not refuse to pay for the improvement, refuse to sell the land, and at the same time demand removal of a structure built in good faith. (Supreme Court E-Library)

2. The right to proper indemnity if the landowner keeps the improvement

If the landowner chooses to appropriate the structure, payment must be based on competent evidence. Courts commonly examine:

Original construction costs;
Receipts and contractor records;
Current condition and depreciation;
Fair market value of the affected portion of the structure;
Increase in the value of the land due to the improvement;
Necessary and useful expenses;
Whether parts of the structure can be separated without serious damage.

The builder is not automatically entitled to every peso claimed. Unsupported estimates, family labor, undocumented cash payments, and expenses unrelated to the disputed structure may be rejected.

3. The right to retain possession pending reimbursement

When the landowner elects to keep the improvement, a builder in good faith may ordinarily retain the affected property until payment of the proper indemnity.

This does not necessarily mean unlimited, rent-free occupation. Courts may award reasonable compensation for the use of the land depending on the landowner’s chosen option, the date of demand, the builder’s continuing use, and the circumstances of the case.

In Technogas Philippines Manufacturing Corporation v. Court of Appeals, the Court applied Article 448 to a boundary encroachment and directed the trial court to determine the land’s price, the value of the encroaching structure, the increase in value, and reasonable compensation for occupancy. (Supreme Court E-Library)

4. Protection against immediate demolition

When Article 448 applies, demolition is not the landowner’s first automatic remedy. Removal may become available when, for example:

The landowner chooses to sell the affected land and the builder unjustifiably fails to pay;
A court-approved or court-imposed lease expires;
The builder defaults under the terms fixed by the court;
The builder is ultimately found to have acted in bad faith;
The parties validly agree to removal.

Neither party should demolish, occupy, fence off, or alter the disputed structure while the case is unresolved without a clear legal basis or court order.

The Landowner’s Two Options Under Article 448

Landowner’s option	What happens	Builder’s principal right
Keep or appropriate the improvement	The landowner pays the indemnity determined under Articles 546 and 548 and applicable case law	Reimbursement and retention until proper payment
Require the builder to buy the land	The builder pays the proper price of the affected land	The builder receives ownership after completing the sale and registration requirements
Land is considerably more valuable than the improvement	The builder cannot be forced to buy; reasonable rent may be imposed if the owner does not appropriate the improvement	Court may fix lease terms if the parties cannot agree

When the land is considerably more valuable

Article 448 expressly states that a builder cannot be compelled to buy the land if the land’s value is considerably more than the value of the building or trees.

There is no fixed percentage in the Civil Code. The court considers appraisals, location, land classification, actual area occupied, structure value, usability, and whether selling only the encroached portion is technically and legally possible.

If the builder rejects the purchase on this ground and the landowner does not appropriate the improvement, the parties may agree on reasonable rent. If they cannot agree, the court may determine the amount and terms.

A forced lease is not necessarily permanent. In Depra and Technogas, the Supreme Court fashioned limited lease arrangements based on the specific facts. Those periods and rental amounts were case-specific and should not be treated as automatic rules for every dispute. (Lawphil)

When Does Good Faith End?

Good faith is usually assessed when the structure was constructed. A later discovery that the building encroaches on another property does not automatically convert the original construction into bad-faith construction.

In Technogas, the Supreme Court rejected the argument that every registered landowner must know the exact technical boundaries stated in the title. A person who is not trained in surveying may be unable to locate precise boundary lines merely by reading a technical description. The builder’s predecessor was therefore presumed to have acted in good faith in the absence of contrary proof. (Supreme Court E-Library)

Good faith may nevertheless cease when the possessor receives facts clearly showing that the occupation is improper, such as:

A verified relocation survey;
A formal demand from the registered owner;
Service of summons in a recovery case;
An admission that the land belongs to another;
Discovery of a defective or cancelled deed;
A final judgment identifying the true boundary.

Continuing to construct after receiving such notice is dangerous. Even if Article 448 protects the original structure, new extensions or improvements made after notice may be treated separately and may be considered made in bad faith.

What Happens When Both the Builder and Landowner Acted in Bad Faith?

Article 453 creates an important exception. If the builder knew that the land belonged to someone else, but the landowner also knew about the construction and allowed it to continue without opposition, the rights of both parties are generally treated as though both had acted in good faith.

The Civil Code considers a landowner in bad faith when construction was done with the landowner’s knowledge and without opposition.

This often arises in family arrangements. A parent, sibling, aunt, uncle, or landowner may allow a relative to construct a concrete house for many years, then later demand immediate removal. Permission to occupy alone does not always create good faith, but knowingly allowing substantial permanent construction can activate Article 453.

In the 2022 case of Agapito v. Agapito, the Supreme Court considered the owner’s prolonged silence, proximity to the property, and evidence showing knowledge of the house. The Court treated the parties’ rights under Articles 448 and 453 because the construction could not realistically have occurred without the owner’s knowledge and consent.

Builder in Bad Faith: Possible Consequences

A builder acts in bad faith when they know that the land belongs to another and have no honest claim of title or right to build.

Under Articles 449 to 452 of the Civil Code:

The builder may lose the improvement without indemnity;
The landowner may demand demolition at the builder’s expense;
The landowner may require the builder to restore the property to its former condition;
The landowner may compel the builder to purchase the land in appropriate circumstances;
The landowner may claim damages;
The builder may still recover genuinely necessary expenses spent to preserve the land.

Bad faith is not established merely because a survey eventually proves the builder wrong. It requires evidence of knowledge, dishonesty, deliberate disregard, or circumstances inconsistent with an honest belief of ownership. (Lawphil)

Common Situations and How the Rules Apply

Boundary encroachment between neighbors

This is the classic Article 448 situation. A firewall, kitchen, eave, fence, garage, or portion of a commercial building crosses the technical boundary.

The first priority is an independent relocation survey by a licensed geodetic engineer. Tax maps, old fences, trees, informal markers, and statements from previous owners are not reliable substitutes for a technical survey tied to approved plans and title descriptions.

A relative builds on family land

Mere family permission does not automatically make the occupant an owner or builder in good faith. If the relative always knew that the land belonged exclusively to someone else and was expected to leave upon demand, Article 448 may not apply.

However, if the registered owner knew about and permitted permanent construction for many years without objection, Article 453 may require the parties to be treated as if they were in good faith.

A tenant improves leased property

A lessee is generally not a builder in good faith under Article 448 because the lessee knows that another person owns the land.

Article 1678 of the Civil Code normally applies. If a lessee makes suitable useful improvements in good faith and the lessor chooses to keep them at the end of the lease, the lessor generally pays one-half of their value at that time. If the lessor refuses to reimburse, the lessee may remove the improvements, subject to the limits stated in the law.

The lease contract may also contain clauses assigning improvements to the lessor, requiring written consent, or prohibiting reimbursement.

In Josefa v. San Buenaventura, the Supreme Court reiterated that a lessee cannot use Articles 448 and 546 to obtain full reimbursement and retention in the same manner as a true builder in good faith. (Supreme Court E-Library)

A buyer under a contract to sell

A contract to sell normally leaves ownership with the seller until the buyer fulfills the conditions for transfer. Because the parties’ rights arise from a contract, Article 448 may not be the controlling rule. The contract, rules on breach, restitution, unjust enrichment, and applicable buyer-protection laws may govern instead.

A co-owner builds on commonly owned land

Article 448 generally does not apply while the property remains under co-ownership. A co-owner is considered an owner of the entire undivided property, not a stranger building on another person’s land.

Reimbursement, consent, partition, and accounting are governed by the Civil Code provisions on co-ownership. The legal treatment may change after partition if the improvement is awarded to a portion belonging exclusively to another co-owner. (Lawphil)

A foreigner builds on Philippine land

Foreign nationals generally cannot acquire private land in the Philippines, except through hereditary succession and other constitutionally permitted situations. Article XII, Section 7 of the 1987 Constitution restricts transfers of private land to persons or entities qualified to acquire lands of the public domain. (Lawphil)

This affects Article 448. A court or settlement cannot lawfully use the “sell the land to the builder” option if the builder is constitutionally disqualified from owning it.

Possible lawful arrangements may include:

Reimbursement and appropriation of the structure by the Filipino landowner;
Removal of separable improvements;
A valid lease;
Ownership through a legally qualified Philippine corporation, subject to constitutional limits;
Other structures permitted by property and investment laws.

Republic Act No. 12252, enacted in 2025, amended the Investors’ Lease Act and permits qualified foreign investors to lease private land for an aggregate period of up to 99 years, subject to investment, registration, use, and other statutory conditions. It does not give every foreign resident a general right to acquire Philippine land. (Lawphil)

Step-by-Step Guide for Resolving a Builder-in-Good-Faith Dispute

1. Stop further construction on the disputed portion

Once a boundary or ownership dispute appears, avoid adding floors, walls, fixtures, or extensions. Continuing after notice can weaken a claim of good faith and increase potential damages.

Take dated photographs and secure the site against deterioration without materially changing the disputed structure.

2. Confirm ownership and technical boundaries

Obtain and compare:

Certified true copy of the Transfer Certificate of Title or Original Certificate of Title;
Deeds of sale, donation, partition, inheritance, or assignment;
Approved subdivision or consolidation-subdivision plans;
Technical descriptions;
Tax declarations and tax maps;
Previous relocation or verification surveys.

A tax declaration is evidence of a claim or possession but is not conclusive proof of ownership. A building permit also does not prove ownership of the land.

Commission a licensed geodetic engineer to conduct a relocation survey. Ask for a signed survey report, sketch plan, photographs of monuments, and identification of the exact area of encroachment.

3. Document the builder’s good faith

Collect evidence showing what the builder honestly believed when construction began:

Deed or contract relied upon;
Title presented by the seller;
Survey used before construction;
Building and occupancy permits;
Architectural and engineering plans;
Receipts, invoices, payrolls, and bank transfers;
Communications with the landowner;
Written permission or consent;
Photographs showing the landowner observing or participating in construction;
Witness statements from contractors, neighbors, or previous owners.

Create a chronology with exact dates. Good faith often turns on what the builder knew at each stage.

4. Obtain separate valuations

Use qualified professionals to determine:

The current fair value of the affected land;
The value of the encroaching portion of the building;
Necessary and useful expenses;
Depreciation and present condition;
Increase in property value caused by the improvement;
Cost and feasibility of partial demolition;
Whether the affected land can legally be subdivided and transferred.

The city or municipal assessor’s valuation is relevant for taxation and court jurisdiction, but it may differ substantially from market value.

5. Send a formal written proposal or demand

A written letter should clearly state:

The title and property details;
The survey findings;
The area affected;
The party’s position on good faith;
The proposed application of Article 448;
A request for the landowner to choose an option;
Proposed valuation or appraisal procedures;
A reasonable period to respond;
A request that neither party demolish or alter the structure while negotiations continue.

Serve the letter personally with a signed acknowledgment, by registered mail, or through a reliable courier that provides delivery records. Notarization is not always legally required, but it can help establish the date and authenticity of the document.

6. Use barangay conciliation when required

Under the Katarungang Pambarangay provisions of Republic Act No. 7160, barangay conciliation is generally a precondition to filing certain disputes when the individual parties actually reside in the same city or municipality, subject to statutory exceptions.

Failure to obtain the required Certificate to File Action can result in dismissal or suspension of the court case. (Lawphil)

A detailed barangay settlement should identify:

The exact land and structure;
The chosen Article 448 option;
The agreed value;
Payment dates;
Survey and subdivision responsibilities;
Taxes and registration expenses;
Turnover or occupancy terms;
Consequences of default;
Whether demolition or removal is permitted.

A barangay settlement not repudiated within the legal period may acquire the force and effect of a final judgment. It may generally be enforced through the lupon within six months or through the appropriate court after that period. (Supreme Court E-Library)

7. Complete the proper transaction

If the landowner chooses to sell the affected portion, the parties may need:

An approved subdivision or segregation plan;
A new technical description;
Written consent of co-owners or spouses when required;
Mortgagee approval if the title is encumbered;
Department of Agrarian Reform clearance for covered agricultural property;
A notarized deed of sale;
Payment of applicable BIR and local transfer taxes and fees;
BIR electronic Certificate Authorizing Registration;
Registration with the Registry of Deeds;
Issuance of updated titles and tax declarations.

If the owner chooses to appropriate the improvement, the settlement should specify the valuation, payment method, release of claims, date of turnover, and responsibility for permits or repairs.

If a lease is used, put it in writing, have it notarized, and consider registration or annotation on the title when necessary to protect the parties against third persons.

8. File the correct court action if settlement fails

The proper action depends on the relief sought:

Forcible entry or unlawful detainer for immediate physical possession under Rule 70;
Accion publiciana when the right to possess must be determined outside the one-year ejectment period;
Accion reivindicatoria when ownership and possession are both claimed;
Quieting of title when an adverse claim clouds ownership;
Specific performance or declaratory relief to enforce or clarify Article 448 rights;
Damages or injunction when demolition, obstruction, or destruction is threatened.

All ejectment cases fall under the jurisdiction of first-level courts. For other real actions, Republic Act No. 11576 generally gives first-level courts jurisdiction when the property’s assessed value does not exceed ₱400,000, while the Regional Trial Court has jurisdiction when the assessed value exceeds ₱400,000. The relevant figure is normally the assessed value, not the market value. (Supreme Court E-Library)

The case must ordinarily be filed where the property is located. The exact classification of the action matters because filing in the wrong court can waste years.

An unlawful detainer case must generally be filed within one year from the relevant final demand to vacate. If that period has passed, a different possessory action may be required. (Lawphil)

Documents Commonly Needed

Document	Where it usually comes from	Why it matters
Certified true copy of title	Registry of Deeds or Land Registration Authority service channels	Establishes registered ownership and annotations
Tax declaration and assessed value	City or municipal assessor	Helps identify improvements, tax history, and court jurisdiction
Real property tax records	Treasurer’s office	Shows tax payments and declared ownership
Relocation survey and sketch plan	Licensed geodetic engineer	Identifies the precise encroached area
Approved survey plans	DENR, LRA, Registry of Deeds, or survey records	Confirms technical boundaries
Building and occupancy permits	Office of the Building Official	Shows the construction history, not land ownership
Plans and construction contracts	Architect, engineer, contractor, or owner	Helps prove scope and cost
Receipts and payment records	Suppliers, contractors, banks	Supports reimbursement claims
Photographs and videos	Parties, neighbors, contractors	Shows construction stages and landowner knowledge
Written demands and replies	Parties or counsel	Establishes notice, objection, and timelines
Appraisal reports	Licensed appraisers or qualified experts	Supports land and improvement valuation
Barangay Certificate to File Action	Barangay or lupon	Required before court in covered cases
Special Power of Attorney	Property owner or authorized principal	Allows a representative to negotiate, sell, settle, or litigate

Documents signed abroad usually require proper notarization and an apostille when issued in a country covered by the Apostille Convention. Documents from non-participating countries generally require the applicable consular authentication process. A Special Power of Attorney involving a sale or settlement should expressly describe the land and the acts the representative is authorized to perform.

Practical Timelines and Cost Factors

The following are common working estimates rather than fixed statutory periods:

Stage	Common practical range	Frequent cause of delay
Obtaining title and tax records	Several days to a few weeks	Old records, title verification, unavailable technical plans
Relocation survey	About 1–4 weeks	Missing monuments, overlapping plans, difficult terrain
Appraisal and engineering assessment	About 1–4 weeks	Lack of plans, concealed structural components
Demand and negotiation	About 2–8 weeks	Disagreement over good faith or valuation
Barangay proceedings	Commonly several weeks	Nonappearance, repeated settings, formation of the pangkat
Sale of a segregated portion	Several months or longer	Survey approval, subdivision, BIR and Registry of Deeds processing
Ejectment case	Several months to more than a year at first level	Service, postponements, appeal
Ordinary property case	Often several years	Expert evidence, multiple parties, appeals, execution

Major expenses may include survey fees, appraisal fees, engineering reports, notarization, court filing fees, publication or service costs, transfer taxes, registration fees, and professional fees. Court docket fees depend on the nature and value of the claim.

Common Mistakes That Weaken a Claim

Relying only on a tax declaration

Tax declarations can support possession or a claim of ownership, but they do not carry the same evidentiary weight as a registered Torrens title.

Treating a building permit as proof of land ownership

A permit shows regulatory approval for construction. It does not settle title, boundary, co-ownership, or the right to occupy another person’s land.

Continuing construction after receiving notice

Work performed after a survey, demand, or court summons may be treated as bad-faith construction even if the original structure was built in good faith.

Demanding full construction cost without valuation evidence

The reimbursement process does not always equal the original cost. Depreciation, present value, increase in property value, necessity, usefulness, and the extent of the encroachment all matter.

Assuming the builder can force a sale

The landowner holds the initial choice under Article 448. The builder can require the landowner to choose but cannot automatically select the purchase option.

Assuming the landowner can immediately demolish

Demolition may be improper when the builder is in good faith and the landowner has not exercised the statutory options.

Ignoring co-owners, spouses, heirs, or mortgagees

A settlement signed by only one person may be ineffective if other registered owners, compulsory heirs, marital property owners, or mortgage holders have legal interests in the land.

Making an oral settlement

Property settlements should be written, technically precise, notarized when appropriate, and registered when they involve transfer or long-term interests in land.

Filing in the wrong court

Jurisdiction may depend on whether the case is ejectment, a real action, a monetary claim, or an action incapable of pecuniary estimation. For real actions, the assessed value stated in the complaint is critical.

Frequently Asked Questions

Can a builder in good faith be evicted immediately?

Not automatically. A builder entitled to Article 448 protection may have a right to retain the affected property until proper indemnity is paid. The result depends on the landowner’s chosen option, the pleadings, and the court’s findings.

Can the landowner force the builder to demolish the house?

If the builder acted in good faith, demolition is generally not the landowner’s immediate first option. It may become available after the landowner chooses a lawful option and the builder fails to comply, or if the builder is found to have acted in bad faith.

Can the builder force the landowner to sell the land?

The builder cannot unilaterally select the sale option. The landowner chooses whether to keep the improvement after indemnity or require the builder to buy the land. The builder may ask the court to compel the landowner to make that choice.

How is reimbursement calculated?

Courts may consider necessary and useful expenses, documented construction costs, depreciation, current fair market value, the improvement’s condition, and the increase in property value. Independent appraisal and engineering evidence are often essential.

Does good faith continue after receiving a demand letter?

The original structure may retain its good-faith character if it was completed before the builder learned of the problem. However, further construction after clear notice may be considered bad faith and may result in damages or loss of reimbursement rights.

Is a person who built with the owner’s permission a builder in good faith?

Permission alone does not necessarily mean the person believed they owned the land. However, when the owner knowingly permits permanent construction and does not object, Article 453 may require the parties to be treated as though both acted in good faith.

Is a tenant a builder in good faith?

Generally, no. A tenant knows that the property belongs to the landlord. Article 1678 and the lease contract, rather than Article 448, normally govern the tenant’s improvements.

Does Article 448 apply between co-owners?

Generally, not while the property remains co-owned. The rules on co-ownership, reimbursement, consent, and partition normally apply.

Can a foreigner use Article 448 to acquire the land?

A foreigner cannot use Article 448 to bypass constitutional land-ownership restrictions. If the foreign builder is not qualified to own private land, the purchase option cannot be implemented unlawfully. Reimbursement, appropriation, removal, or a valid lease may be considered instead.

Is barangay conciliation always required?

No. It depends on the parties’ actual residences, the nature of the parties, the location of the dispute, and statutory exceptions. When it is required, failure to complete barangay proceedings before filing can cause dismissal or suspension of the case.

Key Takeaways

A builder in good faith honestly believes that they own the land or have a valid claim or right to build on it.
Good faith is presumed, but documents, notice, consent, and conduct can overcome that presumption.
Under Article 448, the landowner ordinarily chooses between keeping the improvement after indemnity and requiring the builder to purchase the land.
The landowner cannot simply refuse both options and demand immediate demolition when Article 448 applies.
A builder in good faith may have a right to reimbursement and retention until payment.
If the land is considerably more valuable than the building, the builder cannot be forced to buy it; reasonable rent may be fixed.
Tenants, co-owners, tolerated occupants, buyers under contracts, and foreigners may be governed by different or additional rules.
A relocation survey, certified title records, construction evidence, and independent valuations are usually the most important practical evidence.
Continuing construction after learning of the dispute can turn a manageable boundary problem into a bad-faith claim.
Any settlement involving the sale, lease, removal, or appropriation of improvements should be written, technically precise, and completed through the proper tax and registration processes.
