If a landowner builds with someone else's materials in good faith, can the material owner take them back?

The general rule: landowner pays, material owner may or may not retrieve

Article 447 establishes the baseline: when a landowner uses another person's materials to build, plant, or construct, the landowner is obligated to pay the value of those materials. This is not optional and does not depend on whether the landowner knew the materials belonged to someone else. The payment obligation arises from the fact of use. Whether the material owner can actually take the materials back is a separate question — and it depends on whether removal is physically possible without damaging or destroying the work.

When the material owner can reclaim the materials

In a good-faith scenario, the material owner has a right to remove the materials — but only if they can do so without injuring the construction or destroying the plantings or works. In practice, once materials have been incorporated into a structure — bricks laid into a wall, lumber framed into a building — removal without damaging the work is often impossible. In those cases, the material owner's only remedy is monetary: the landowner must pay the value of the materials. The right to physical recovery is real, but limited to situations where the materials can be separated cleanly.

When the landowner acted in bad faith

Bad faith changes everything. If the landowner knew the materials belonged to someone else and used them anyway — without permission and without a valid basis for believing they had the right to do so — two consequences follow. First, the material owner may remove the materials in any event, regardless of whether removal damages the construction. The landowner cannot protect their building by citing the disruption removal would cause, because the landowner's own bad faith created the situation. Second, the material owner is also entitled to damages for the harm caused by the landowner's wrongful conduct.

What this means if your materials were used without permission

If someone built on their own land using materials that belong to you, your options depend on whether they acted in good faith or bad faith, and on whether your materials can physically be recovered. If recovery is impractical, the realistic remedy is a claim for the materials' value plus damages if bad faith can be shown. Documenting ownership of the materials before they were used — receipts, delivery records, witness accounts — is important for any claim. The longer you wait after learning about the unauthorized use, the harder it can become to establish the facts and the original value of the materials.
