Short answer. Generally yes. In a lump-sum sale of land described by its boundaries, the seller must deliver everything inside those boundaries even when the true area is larger than the figure written in the deed, and the price does not change. What you bought is the enclosed land, not the stated number of square meters.
What the law says
the vendor shall be bound to deliver all that is included within said boundaries, even when it exceeds the area or number specified in the contract
Civil Code, Article 1542 — Sale of Realty for a Lump Sum (Cuerpo Cierto). Read the full provision →
A lump-sum sale is a sale of the whole identified land
Article 1542 governs a sale for a lump sum (in Spanish, cuerpo cierto) — one price for a definite piece of land, not a price computed at so much per square meter. In that kind of sale the law says there shall be no increase or decrease of the price, although there be a greater or less area than that stated in the contract. So the number of square meters recited in the deed is a description, not the thing you actually bought. What you bargained for was the specific parcel marked out by its boundaries, whatever its true measurement turns out to be.
The boundaries control over the stated area
Because the boundaries are what define the property, the article binds the seller to deliver all that is included within said boundaries, even when it exceeds the area or number specified in the contract. If the land inside the corners is larger than the deed's figure, the surplus is yours at no extra cost, and you do not owe more money for it. The boundaries are treated as indispensable in every conveyance of real estate; the area is secondary. This is the opposite of a sale priced per unit of measure, where a shortage or excess is adjusted peso for peso.
When the seller cannot deliver everything inside the lines
The rule cuts both ways. If the seller turns out to be unable to deliver the whole area enclosed by the stated boundaries, he suffers a proportionate reduction in the price for what is lacking. And if you as buyer do not accept that failure, the contract may be rescinded instead. So the seller cannot quietly hand over less than the boundaries enclose and keep the full price; you are entitled either to a price reduction matched to the shortfall or to walk away from the sale, depending on how you choose to respond.
Where this rule does not apply
This protection is tied to the lump-sum form. If your deed instead fixes the price at a rate for each unit of measure, a different rule applies and the price is adjusted up or down to match the real area. The boundaries must also be genuinely certain; a vague or disputed perimeter changes the analysis. And the article settles price and delivery between buyer and seller — it does not by itself resolve a boundary fight with a neighbour, correct a title, or override what a survey and the Registry of Property actually show on the ground.
