Isa sa pinakamadalas itanong sa akin: “Broker Carla, my neighbor built on part of my lot. What can I do?”
The story
Aling Nena bought a titled lot in Batangas years ago. Her neighbor, Mang Ben, recently put up a new hollow-block fence and a small extension to his house. Something looked off, so Nena hired a geodetic engineer. The relocation survey showed the fence sits about two meters inside her lot.
“May titulo ako,” she says. “Puwede ko bang ipagiba?” The answer surprises many owners: it depends on whether Mang Ben built in good faith. (Aling Nena and Mang Ben are fictional.)
The short answer
Your title protects your ownership. Registered land cannot be acquired by prescription or adverse possession (PD 1529, Sec. 47), so years of occupation will not make the strip his. But what you can do about the structure depends on good faith. If your neighbor honestly believed the land was his, the Civil Code gives you a choice under Article 448, but you generally cannot simply order demolition. If he built knowing the land was yours, Articles 449 to 451 let you demand demolition at his expense, plus damages.
The full explanation
If he built in good faith (Art. 448)
A builder in good faith is one who builds believing the land is his, for example because he relied on wrong survey markers. In that case, the landowner chooses between two options:
- Appropriate what was built by paying the indemnity provided in Articles 546 and 548; or
- Oblige the builder to pay the price of the land, unless the land is considerably more valuable than what was built, in which case he pays reasonable rent (and if you cannot agree on the terms, the court fixes them).
If he built in bad faith (Arts. 449 to 451)
A person who builds in bad faith on another’s land loses what is built without right to indemnity (Art. 449). The landowner may demand demolition or removal at the builder’s expense, or compel him to pay the price of the land (Art. 450). The builder in bad faith is also liable for damages (Art. 451).
What the Supreme Court said
In Rosales v. Castelltort, G.R. No. 157044, October 5, 2005 (Third Division), the owners of Lot 17 in a subdivision in Los Baños, Laguna discovered that a buyer had built his house on their lot. The cause: a geodetic engineer’s crew had placed the boundary monuments on Lot 17 instead of Lot 16, and the buyer was pointed to the wrong lot.
The Court held that good faith is presumed, and that the buyer, who relied on a clean title and the surveyor’s markers, was a builder in good faith until he was told of the owners’ claim. Good faith ends “from the moment defects in the title are made known to the possessor.” The Court stressed that under Article 448 “the choice belongs to the owner of the land” and that the landowner “cannot refuse to exercise either option.” The case was sent back to the trial court to determine the values needed to apply Article 448.
Lesson: notify your neighbor in writing as soon as you discover the encroachment. Whatever he builds after he knows of your title is no longer in good faith.
Step by step
- Confirm the boundary. Get a relocation survey from a licensed geodetic engineer using your approved survey plan and title technical description.
- Talk first, then put it in writing. Show the survey and send a written demand. This also marks the end of any claimed good faith.
- Barangay conciliation. If you both live in the same city or municipality, the dispute usually must go through Katarungang Pambarangay under the Local Government Code before a court case can be filed.
- Court, if needed. A lawyer will choose the right case depending on how long the encroachment has been there and what you want: ejectment, an action to recover possession, or an action to recover ownership.
- Settle smartly. Many neighbors end up with a sale of the strip, a lease, or moving the fence. A broker can help you check fair value.
Costs: relocation survey fees, legal fees and filing fees vary by location, lot size and case, so get written quotes. I am not listing amounts because I could not verify a current official fee schedule that applies to every case.
What this means for you
- Don’t demolish it yourself. Taking the law into your own hands can expose you to liability.
- Act early and in writing. Delay makes the case harder and may affect which remedy is available.
- Know your options. Good faith or bad faith decides whether you can demand removal or must choose under Art. 448.
Documents to prepare: certified true copy of your title, approved survey plan and technical description, tax declaration, real property tax receipts, the relocation survey report, photos with dates, and copies of letters sent.
Where to go: Registry of Deeds (title), a licensed geodetic engineer (survey), DENR/CENRO or LMB (approved plans, if needed), your barangay (conciliation), and a lawyer.
FAQ
Can my neighbor own the strip because he has occupied it for many years?
Not if your land is titled. Under PD 1529, Sec. 47, no title to registered land can be acquired by prescription or adverse possession.
Can I just tear down the fence?
Don’t. Go through demand, barangay conciliation and, if needed, the courts.
Who pays for the relocation survey?
Usually the party who orders it. Neighbors sometimes agree to share the cost and use one engineer.
What if the survey shows I am the one encroaching?
The same rules apply in reverse. Talk to your neighbor early; buying the strip or adjusting the fence is often the cheapest fix.
