You do not know where your land ends: fixing and marking boundaries

Last reviewed: August 17, 2026VerifiedPoder Judicial

In short

These are two distinct operations the 2020 Civil Code defines separately. A deslinde is the operation fixing the material limits of a plot that have become confused. Amojonamiento is the act of placing stable markers on the limits once established. The owner may request them, summoning the owners of adjoining plots, and so may those holding real rights over the plot even without possessing it. The deslinde may be carried out by any technical surveying procedure, and the abutters must appear at the appointed place, day and hour, in person or by representatives, with sufficient titles of ownership supporting their right — the Code defines a sufficient title as one adequately providing the plot’s area and the remaining necessary data. Lacking sufficient titles, the deslinde may be done from what possession shows. And if the titles do not determine the boundary and the question cannot be resolved by possession or other evidence, the Code requires dividing the disputed ground in equal parts; if the titles indicate more or less space than exists, the surplus or shortfall is distributed proportionally. Deslinde and amojonamiento actions are imprescriptible, without prejudice to rights acquired by prescription.

The 2020 Civil Code replaced the 1930 one and reorganised the rules on closing, fixing and marking property boundaries. Any advice predating November 2020 should be revisited.

What is it?

The Code separates them in an article of their own. The deslinde fixes where the limits are when they have become confused — an operation on the plan and on the ground. The amojonamiento places stable markers on those established limits: the boundary stones. They go in that order and serve different purposes, so asking for "a deslinde" when what you want is physical marks on the ground leaves the job half done. Both rest on a prior right the Code recognises in the preceding article: the owner has the right to close, fence and protect their plot by walls, fences, hedges or any other means compatible with the applicable special law, without prejudice to the easements and the legal and voluntary restrictions affecting the plot.

Who can do it?

The owner has the right to fix and mark the boundaries of their plot, summoning the owners of adjoining plots. The same power belongs to those holding real rights over the plot, regardless of not possessing it — so possession is not required to request it. Summoning the abutters is not a courtesy: it is part of the procedure, and it is they who must appear with their titles.

Step by step

  1. Step 1: Look at your title before the land

    A deslinde is settled first on paper. The Code requires the abutters to appear with sufficient titles of ownership supporting their right, and defines what counts as sufficient: one adequately providing the plot’s area and the remaining data needed for the deslinde and amojonamiento. If your deed does not state the area, or states it in a way that does not allow the boundaries to be located, you know where the problem starts. And if your deed’s area does not match the land itself, that has its own procedure — the rectificación de cabida before OGPe, with its own guide.

  2. Step 2: Summon the abutters: it is not optional

    The right to fix and mark boundaries is exercised with the adjoining owners summoned, and the Code spells out the burden falling on them: they must appear, in person or by representatives, at the appointed place, day and hour, with sufficient titles of ownership supporting their right. A deslinde done behind a neighbour’s back does not match what the Code describes, and leaves the result open to challenge exactly once you have already paid the surveyor.

  3. Step 3: Have the deslinde done by survey

    The Code imposes no single method: the deslinde may be carried out by any technical surveying procedure. What it does impose is the order of sources. First, sufficient titles. Failing those, the deslinde may be done from what the abutters’ possession shows. And only if the titles do not determine the boundary and the question cannot be resolved by possession or other evidence does the division rule come in.

  4. Step 4: If nothing settles it, the Code does the arithmetic

    Two rules settle the matter rather than leaving it hanging. If the titles do not determine the boundary or the area belonging to each owner and the question cannot be resolved by possession or other evidence, the deslinde must be done by dividing the disputed ground in equal parts. And if the abutters’ titles indicate more or less space than the land as a whole comprises, the surplus or shortfall must be distributed proportionally. In other words: a title claiming too much does not hand anyone the whole portion, and where land is short, one owner does not absorb the loss alone.

  5. Step 5: Mark it: put the markers in the ground

    Once the limits are fixed, the second act remains. Amojonamiento is the act of placing stable markers on the established limits. It is what stops the argument restarting in five years, and it is the difference between having a plan and having a boundary. And once marked, remember the right the Code recognises just before: you may close, fence and protect your plot with walls, fences, hedges or any other means compatible with the applicable special law, without prejudice to the easements and restrictions affecting it.

  6. Step 6: Do not confuse "never prescribes" with "time does not matter"

    The Code says deslinde and amojonamiento actions are imprescriptible — and repeats it in the prescription title, declaring that the action to fix boundaries between adjoining properties does not prescribe. But it adds five decisive words: without prejudice to rights acquired by prescription. Translated: your deslinde action never lapses, but while you wait, the neighbour’s possession of the disputed strip may be turning into their ownership through the passage of time. Imprescriptibility protects the right to ask for the boundary, not the land.

Where to do it

The deslinde itself is done by a surveyor, by any technical surveying procedure, with the abutters summoned. If there is a conflict that titles and possession cannot resolve, the action goes to the Court of First Instance. Changes affecting the plot’s registry description are handled at the Registro de la Propiedad.

What to do if something goes wrong

If the neighbour moved the fence, look first at what the titles say: the Code puts sufficient titles ahead of possession, and defines a sufficient title as one providing the area and the other necessary data. If your deed does not state the area, that is the first repair. If the neighbour does not appear when summoned, the Code contemplates the deslinde being done from what possession shows, but document the summons. If the dispute is over a strip the neighbour has occupied for years, do not rely on the action never prescribing: imprescriptibility is without prejudice to rights acquired by prescription, and there the clock does run. If the problem is not the boundaries but that your deed’s area does not match the land, that is a rectificación de cabida before OGPe. And if what exists is an encumbrance someone claims over your plot, the route is different: the negatory action, in which you benefit from the presumption that property is free, though if the defendant proves the encumbrance it falls to you to prove it was extinguished.

Common mistakes

  • Asking for the deslinde and stopping there: the amojonamiento is the separate act placing stable markers on the limits.
  • Doing the deslinde without summoning the adjoining owners.
  • Turning up with a deed that does not state the area: the Code requires a title providing the area and other necessary data.
  • Believing possession outranks title: the Code turns to possession only where sufficient titles are lacking.
  • Relying on the action never prescribing and letting years pass: imprescriptibility is without prejudice to acquisitive prescription.
  • Expecting to keep the whole strip because your title says more metres: surplus or shortfall is distributed proportionally.
  • Confusing the deslinde with the rectificación de cabida, a different procedure before OGPe.

Frequently asked questions

What is the difference between deslinde and amojonamiento?

The Code defines them separately: a deslinde is the operation fixing the material limits of a plot that have become confused; amojonamiento is the act of placing stable markers on the established limits. First you determine where the boundary is, then you mark it on the ground.

What if the titles do not clarify where the boundary is?

The Code gives two exits in order. Lacking sufficient titles, the deslinde may be done from what the abutters’ possession shows. And if the titles do not determine the boundary and the question is not resolved by possession or other evidence, the deslinde must be done by dividing the disputed ground in equal parts.

Can I request it even if I do not possess the plot?

Yes. The owner has the right to fix and mark their plot’s boundaries with the abutters summoned, and the Code adds that the same power belongs to those holding real rights, regardless of not possessing.

Can I run out of time to claim?

The action does not, but the land can. Deslinde and amojonamiento actions are imprescriptible, without prejudice to rights acquired by acquisitive prescription. So you can always ask for the boundary, but if the neighbour possessed the strip for the time the law requires, they may have acquired it in the meantime.

Can I fence my land once the boundary is fixed?

The Code expressly recognises it: the owner has the right to close, fence and protect their plot by walls, fences, hedges or any other means compatible with the applicable special law, without prejudice to the easements and the legal and voluntary restrictions affecting the plot.
