My Neighbor Built a Fence or House on My Land: What Are My Options?

Your options depend almost entirely on one question: did your neighbor build in good faith? If he did, Article 448 of the Civil Code gives you the choice – either buy the structure by paying the required indemnity, or require him to buy the land he occupied – and the Supreme Court has held that you cannot refuse both and simply demand demolition. If he built in bad faith, the balance reverses: he loses what he built without indemnity, and you may demand demolition at his expense, or compel him to buy the land, with damages either way.

Decision snapshot

Situation	Governing articles	Landowner’s options
Neighbor built in good faith	Articles 448, 546 and 548	Appropriate the works after paying indemnity, or oblige him to buy the land. Demolition is not one of the choices
Good faith, but the land is worth considerably more than the structure	Article 448	He cannot be forced to buy the land; if you do not appropriate the structure, he pays reasonable rent on terms fixed by agreement or by the court
Neighbor built in bad faith	Articles 449, 450 and 451	He loses the work without indemnity; you may demand demolition at his expense or compel him to buy the land, plus damages
You knew of the construction and did not object	Article 453	The law treats both parties as having acted in good faith, returning you to the Article 448 options
Only a fence or plants cross the line	Articles 430, 448 and following	Same framework, usually resolved by agreement once a survey settles the line

Key takeaways

• Good faith is presumed. Article 527 puts the burden of proving bad faith on the person who alleges it.
• The choice under Article 448 belongs to the landowner, not the builder – but it is a choice between two options, not a right to demand removal.
• A written warning before or during construction is what usually converts good faith into bad faith, and it changes the whole outcome.
• You still need a relocation survey. None of these rules can be applied until the boundary and the encroached area are established.
• Never demolish the structure yourself. Doing so converts a case you are likely to win into one you may lose.

The rule when the builder is in good faith

Article 448, as reproduced by the Supreme Court in Depra v. Dumlao, provides: “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.”

The sentence most landowners need to read twice comes from the same decision: “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 erected.”

The reason is practical rather than sentimental. Article 448 is designed to avoid the waste of destroying a building that was put up honestly, while still making sure the landowner is not deprived of his property for nothing. Somebody ends up owning both the land and the structure; the law simply decides who pays whom.

What the indemnity covers

If you choose to appropriate the structure, Article 546 applies: “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.”

Two consequences follow. You choose between reimbursing the expenses and paying the increase in value. And until you pay, a builder in good faith has a right of retention – he may stay. Article 548 deals separately with expenses for pure luxury or mere pleasure, which are not refunded, though the possessor in good faith may remove the ornaments if the property suffers no injury.

What good faith means here

Article 526 defines it: “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.” Article 527 supplies the presumption: “Good faith is always presumed, and upon him who alleges bad faith on the part of a possessor rests the burden of proof.”

In Tecnogas Philippines Manufacturing Corp. v. Court of Appeals (G.R. No. 108894, 10 February 1997), a structure encroached on a narrow strip of the neighbor’s lot. The Court held that “Article 527 of the Civil Code presumes good faith, and since no proof exists to show that the encroachment … was done in bad faith by the builder of the encroaching structures, the latter should be presumed to have built them in good faith,” and confirmed that a buyer of the property “is deemed to have stepped into the shoes of the seller in regard to all rights of ownership over the immovable sold, including the right to compel the private respondent to exercise either of the two options provided under Article 448.”

That last point matters in practice: encroachments are usually inherited along with the house. The current owner of the encroaching structure can be in good faith even though the wall was built decades ago by someone else.

When the builder is in bad faith

The articles are short and severe. As quoted by the Court in Pen Development Corporation v. Martinez Leyba, Inc. (G.R. No. 211845, 9 August 2017):

• Article 449: “He who builds, plants or sows in bad faith on the land of another, loses what is built, planted or sown without right to indemnity.”
• Article 450: “The owner of the land on which anything has been built, planted or sown in bad faith may demand the demolition of the work, or that the planting or sowing be removed … at the expense of the person who built, planted or sowed; or he may compel the builder or planter to pay the price of the land.”
• Article 451: “In the cases of the two preceding articles, the landowner is entitled to damages from the builder planter or sower.”

In that case the builders had been given repeated written notice that they were encroaching and continued to build anyway. They forfeited the improvements without compensation and remained liable in damages.

This is why the written notice is the most valuable document in the file. A dated, served letter attaching a survey plan is what separates the two regimes. Sent before or during construction, it can move the case from Article 448 to Article 449.

The reverse also exists. Article 453 provides that where the landowner knew of the building and did not object, both parties are treated as having acted in good faith – so silence while a neighbor’s wall goes up has a legal price.

How this is actually resolved

A court applying Article 448 does not simply issue an order to demolish or to pay. It determines the present fair value of the land occupied and of the structure, requires the landowner to exercise the option within a set period, and then supervises the consequences – payment and transfer if the landowner appropriates, execution of a deed if the builder buys the land, or the fixing of lease terms if neither is possible. Expect a process in stages, and expect valuation evidence to matter as much as the legal argument.

Step by step: what to do next

1. Stop and document. Photograph the structure, dated, from several angles before anything changes.
2. Commission a relocation survey from a licensed geodetic engineer, with written notice of the date to your neighbor. The report should state the width and area of the encroachment.
3. Send a written notice immediately if construction is ongoing, attaching the survey and asking that work stop. Serve it in a provable way. This is the step that fixes good or bad faith.
4. Decide which option you actually want. Paying for the structure and keeping the whole lot, or being paid for the encroached strip, have very different costs.
5. Get valuation evidence – zonal values, the assessor’s schedule of market values, or an appraiser – for both the land and the structure.
6. Go through the barangay where the property is located, and put any agreement in writing with the survey reference attached.
7. File the appropriate action with a lawyer or the Public Attorney’s Office if no settlement is reached. Jurisdiction follows the assessed value under Republic Act No. 11576.

Frequently asked questions

Can I just make him tear it down?

Only if he built in bad faith. Where the building was done in good faith, Depra v. Dumlao is explicit that the landowner cannot refuse both options and compel removal. Demolition is the remedy under Article 450, which applies to bad faith.

It is only a fence, not a house. Same rules?

The same framework applies to anything built, planted or sown. In practice a fence is cheap enough that the parties usually settle once a survey establishes the line – which is exactly why the survey should come before the argument. See Land boundary dispute: what to do when your neighbor encroaches.

I told him years ago that he was over the line. Does that make him a builder in bad faith?

It helps only if you can prove it and only as to what was built afterwards. A verbal complaint at a family gathering is hard to establish. A dated letter with proof of service, attaching a survey, is the evidence that works.

He refuses to pay for the strip and refuses to move. What happens?

Then the court decides. If he built in good faith and the land is worth considerably more than the structure, he cannot be forced to buy it, and the outcome is a lease at a rent fixed by the parties or by the court. If he built in bad faith, demolition at his expense is available.

Can he keep occupying my land while the case runs?

A builder in good faith has a right of retention under Article 546 until the indemnity is paid, so yes, in that scenario he may remain. That right does not exist for a builder in bad faith.
