Boundary Encroachments and Relocation Surveys in the Philippines: Builder in Good Faith vs Builder in Bad Faith When a Fence Crosses the Property Line
Introduction: Why a Relocation Survey Matters Before You Build a Fence
Fence construction is often treated as routine, but boundary mistakes can trigger expensive disputes—demolition, damages, and loss of improvements. In Philippine civil law, a fence or perimeter wall that intrudes into a neighbor’s titled land may place the builder under the rules on builders, planters, and sowers, with outcomes heavily influenced by whether the builder is in good faith or bad faith. A relocation survey is the most reliable way to verify the correct property line before construction and helps prevent an encroachment finding that can later be used to prove bad faith.
Governing Law: Civil Code Rules on Encroachment
The Civil Code of the Philippines (Republic Act No. 386, 1949) sets out the governing framework when a person builds on land that turns out to belong to another.
When the builder is in good faith, the applicable rule is generally Article 448 of the Civil Code (1949). It gives the landowner choices, but requires indemnity if the landowner appropriates the improvement.
When the builder is in bad faith, Articles 449 to 451 of the Civil Code (1949) become decisive: the builder may lose what was built without indemnity, and the landowner may demand removal or demolition at the builder’s expense plus damages.
What Counts as “Good Faith” vs “Bad Faith” in Boundary Disputes
Good faith: honest belief the land is yours, without awareness of a defect
Philippine jurisprudence consistently treats good faith as an honest belief that the land being built upon belongs to the builder, with ignorance of any defect in title or boundary. In Sta. Lucia Realty and Development, Inc. v. Lumawag, et al. (2023), the Court reiterated that good faith is presumed and the burden of proving bad faith rests on the party alleging it, emphasizing that the builder relied on permits and technical documents in believing the construction was on the correct lot.
Bad faith: building despite notice, warnings, or obvious reasons to verify
Bad faith commonly arises where the builder proceeds despite being informed of encroachment or despite having the means and obligation to verify boundaries but choosing not to. In Pen Development Corporation, et al. v. Martinez Leyba, Inc. (2017), the Court held builders in bad faith where they continued construction despite repeated demands to stop and failed to conduct their own survey to clarify encroachment. Similarly, Princess Rachel Development Corporation, et al. v. Hill View Marketing Corporation, et al. (2020) treated a developer as a builder in bad faith where it proceeded notwithstanding information about encroachment and its capacity to verify boundaries.
How the Civil Code Allocates Rights and Remedies
If the builder is in good faith (Civil Code, Article 448)
Under Article 448 of the Civil Code (1949), where a structure is built in good faith on another’s land, the landowner generally has two principal options:
(1) Appropriate the improvement as his own, but only after paying indemnity (as referenced by Article 448).
(2) Compel the builder to buy the land (or, if sowing is involved, to pay rent). However, if the value of the land is considerably more than the value of the improvement, the builder cannot be compelled to buy; in that case, the builder pays reasonable rent if the landowner does not appropriate the improvement after indemnity.
Angeles v. Pascual, et al. (2011) applied Article 448 and explained the landowner’s options and the limitation where the land is considerably more valuable than the improvement, leading to a lease-type outcome rather than forced sale.
If the builder is in bad faith (Civil Code, Articles 449 to 451)
When the builder is in bad faith, the Civil Code (1949) gives the landowner stronger remedies:
- Article 449: the builder in bad faith loses what is built without any right to indemnity.
- Article 450: the landowner may demand demolition/removal to restore the former condition at the builder’s expense, or compel the builder to pay the price of the land.
- Article 451: the landowner is entitled to damages.
Pen Development Corporation, et al. v. Martinez Leyba, Inc. (2017) and Princess Rachel Development Corporation, et al. v. Hill View Marketing Corporation, et al. (2020) illustrate a common pattern: once a party is on notice of encroachment, continuing construction strongly supports a finding of bad faith, with loss of indemnity and exposure to demolition and damages.
When the Landowner Can Also Be in Bad Faith (and Why It Matters)
The Civil Code (1949) also addresses situations where the landowner’s conduct contributes to the wrongful building. Article 453 provides that if there is bad faith on both sides, their rights are treated as though both acted in good faith. It further clarifies that there is bad faith on the part of the landowner when the construction is done with the landowner’s knowledge and without opposition.
In Princess Rachel Development Corporation, et al. v. Hill View Marketing Corporation, et al. (2020), the Court examined whether the landowner knew of the encroachment and whether it promptly asserted its rights upon discovery—facts that can affect whether the landowner is treated as in good faith or bad faith.
Why Relocation Surveys Are Central in Fence Encroachment Conflicts
A relocation survey is not merely a technical step; it is evidence. In disputes, the question often becomes: Did the builder reasonably verify the boundary before building, and how did the builder respond after receiving notice of a possible encroachment?
Courts tend to view builders more favorably when they can show they relied on competent technical verification and acted promptly to avoid intrusion. Conversely, failure to verify boundaries—especially after warnings—can support a conclusion that the builder ignored a serious risk and proceeded anyway, consistent with the bad-faith findings in Pen Development Corporation, et al. v. Martinez Leyba, Inc. (2017) and Princess Rachel Development Corporation, et al. v. Hill View Marketing Corporation, et al. (2020).
Common Scenarios and Likely Legal Consequences
Scenario 1: Fence built based only on “old mohon” markers or verbal assurances
If the fence later crosses the neighbor’s property, the builder may still claim good faith, but the absence of a current relocation survey makes that claim harder to sustain—especially if circumstances suggested uncertainty (missing markers, irregular lots, prior boundary disagreements).
Scenario 2: Builder receives a demand letter or survey showing encroachment but continues building
Continuing construction despite notice is a frequent path to being classified as a builder in bad faith, similar to the conduct criticized in Pen Development Corporation, et al. v. Martinez Leyba, Inc. (2017).
Scenario 3: Developer or seller provided the wrong lot or inaccurate layout, buyer built relying on permits
Where a buyer builds relying on permits and developer-issued approvals, courts may recognize the buyer as a builder in good faith, as discussed in Sta. Lucia Realty and Development, Inc. v. Lumawag, et al. (2023). However, the builder’s own negligence (for example, ignoring obvious red flags) may still have consequences, including limited damages findings depending on proof and final judgments.
Quick Comparison Table: Builder in Good Faith vs Builder in Bad Faith
| Issue | Builder in Good Faith | Builder in Bad Faith |
|---|---|---|
| Legal basis | Civil Code, Article 448 (1949) | Civil Code, Articles 449–451 (1949) |
| Landowner’s main options | Appropriate improvement with indemnity, or require builder to buy land (subject to limitations) | Demolition/removal at builder’s expense, or compel builder to buy land; plus damages |
| Builder’s risk on improvements | May be indemnified if landowner appropriates; may be required to purchase land or lease if land value is much higher | May lose improvements without indemnity; exposed to demolition/removal and damages |
| Typical factual trigger | Honest mistake; reliance on permits/technical documents; no notice of encroachment | Construction despite notice/warnings; refusal to verify boundaries; continued building during dispute |
What Homeowners and Builders Should Do Before Building a Fence
- Commission a relocation survey by a licensed geodetic engineer and keep the signed plan, technical report, and monuments/photos as records.
- Confirm boundaries against the title and technical descriptions, not only against physical markers that may have moved.
- Address objections immediately. If a neighbor raises a boundary concern, pause construction and verify. Continuing despite notice is a recurring basis for bad-faith findings in Supreme Court decisions.
- Document communications (letters, emails, site meeting notes). Boundary cases often turn on notice and response.
- Consider an amicable boundary agreement after survey results, especially where encroachment is minor and both parties prefer settlement over demolition.
Conclusion: Surveys Prevent Disputes, and Conduct After Notice Shapes Liability
When a fence crosses a property line, Philippine law does not treat all mistakes equally. Under the Civil Code (Republic Act No. 386, 1949), the classification of the builder as acting in good faith or bad faith can determine whether the landowner must indemnify, whether demolition can be compelled, and whether damages may be awarded. Supreme Court decisions emphasize that proceeding with construction despite notice of encroachment strongly supports a finding of bad faith, while reliance on proper permits and technical verification supports good faith. A relocation survey before fence construction remains one of the clearest safeguards—both to avoid encroachment and to demonstrate responsible conduct if a dispute arises.
