Discovering cracks or leaks after buying, or that a third party claims the property, does not leave the buyer defenseless. The Código Civil (Civil Code; Gaceta Oficial No. 2.990 Extraordinario, July 26, 1982) obliges the seller to answer even if the contract does not say so: for evicción (third-party claim to the property), that is art. 1.504. For a specific lawsuit you need a lawyer.
The seller's two warranties
Article 1.503 defines saneamiento (seller's warranty):
"Por el saneamiento que debe el vendedor al comprador, responde aquél 1º. De la posesión pacífica de la cosa vendida. 2º. De los vicios o defectos ocultos de la misma."
In English: through the saneamiento the seller owes the buyer, the seller answers, first, for the peaceful possession of the thing sold and, second, for its hidden vices or defects.
| Warranty | Covers | Articles |
|---|---|---|
| Saneamiento por evicción | A third party taking all or part of the property from the buyer, or imposing undeclared encumbrances on it | 1.504 to 1.517 |
| Saneamiento por vicios ocultos (warranty against hidden defects) | Concealed defects that make the property unfit for its use or reduce that use | 1.518 to 1.525 |
When a third party claims the property: evicción
There is evicción when someone with a better right deprives the buyer of all or part of the property, or seeks to burden it with undeclared encumbrances (art. 1.504). For example, an heir who did not sign the sale or a mortgage that nobody disclosed.
If you suffer evicción, article 1.508 entitles you to demand from the seller:
The seller must also reimburse useful repairs and improvements (art. 1.511) and, if the property rose in value, pay that excess (art. 1.510). If you lose a part so important that you would not have bought without it, you can ask for the sale to be rescinded (art. 1.513).
If a third party sues you, have the seller notified of that lawsuit in the terms of the Código de Procedimiento Civil (Code of Civil Procedure). Under article 1.517, if you do not and the seller proves they had sufficient defenses to win, the warranty ends.
If you still owe part of the price, article 1.530 lets you suspend payment when you are disturbed, or have a well-founded fear of being disturbed, by a mortgage action or an action to recover ownership, until the seller ends the disturbance, unless the seller gives sufficient security or the contract says otherwise.
The best protection comes beforehand: check the certificación de gravámenes (lien certificate) and the chain of title before signing. The risk of evicción is higher when you buy bienhechurías or a property with a título supletorio (improvements on land, or a court-issued supplementary title), because that title leaves third parties' rights intact.
Vicios ocultos: what they are and what you can ask for
Article 1.518 defines the vicio oculto:
"El vendedor está obligado al saneamiento de la cosa vendida por los vicios o defectos ocultos que la hagan impropia para el uso a que esté destinada o que disminuya el uso de ella de tal manera que si el comprador los hubiera conocido, no la habría comprado o hubiera ofrecido un precio menor."
In English: the seller must give the warranty for hidden vices or defects that make the thing sold unfit for its intended use, or that reduce its use so much that, had the buyer known of them, they would not have bought it or would have offered a lower price.
Three conditions follow from this:
Under article 1.520, the seller answers for hidden defects even if they did not know of them, unless agreed otherwise. Their good faith only changes how much they must pay.
The Code does not mention extensions built without a permit. Whether a problem like that is a hidden defect depends on whether it meets article 1.518 and was not apparent; a judge decides case by case.
Returning the property or reducing the price
Article 1.521 gives you a choice:
"En los casos de los artículos 1.518 y 1.520 el comprador puede escoger entre devolver la cosa haciéndose restituir el precio, o retenerla haciéndose restituir la parte del precio que se determine por expertos."
In English: in the cases of those two articles, the buyer may choose between returning the thing and getting the price back, or keeping it and getting back the part of the price that experts determine.
| Option | Usual name | What you get |
|---|---|---|
| Return the property | Acción redhibitoria (action to undo the sale) | The return of the price |
| Keep the property | Acción estimatoria or quanti minoris (price reduction action) | The part of the price that the experts set |
You have to pick one. In 2012, a superior court in Miranda declared inadmissible the claim of a buyer who asked for both at once over a house with cracks and damp, because they exclude each other. It is a lower-court ruling, but it shows the risk.
What is added to the refund depends on what the seller knew:
The deadline: one year from the tradición
This is the most delicate point. Article 1.525 says the buyer must bring the acción redhibitoria "en el término de un año a contar desde el día de la tradición" (within one year from the day of delivery) when real estate is involved. For property, article 1.488 says the seller makes the tradición (legal delivery) "con el otorgamiento del instrumento de propiedad" (by executing the title instrument), that is, with the execution of the sale document.
The year runs from the sale, not from when you discover the defect. In 2014, a court in Trujillo declared an action for hidden defects time-barred, counting the year from the recorded sale. The same article excludes the acción redhibitoria in judicial auctions.
Article 1.525 names only the acción redhibitoria and does not say expressly whether that same year applies to the price reduction. The courts have applied it to both: in 2025, in a case about a vehicle, the Sala de Casación Civil (Civil Cassation Chamber) of the TSJ (the Supreme Court) wrote that the redhibitoria and the quanti minoris "deben ser interpuestas dentro de los plazos establecidos en el artículo 1.525" (must be brought within the time limits set in that article), and in 2005 a superior court in Táchira applied the year to a price reduction. Treat the year as the limit for both and consult a lawyer as soon as you detect the problem.
Clauses that exclude the warranty and their limits
Many documents say the seller does not answer for saneamiento. The law allows it, with limits:
Read these clauses in the opción de compra-venta (purchase option agreement) and negotiate them before the final document, because that is the text that is recorded.
Structural failures: ten years for ruin
When the defect is structural, another rule may apply, aimed at whoever built the property. Article 1.637, in the chapter on construction contracts, says:
"Si en el curso de diez años a contar desde el día en que se ha terminado la construcción de un edificio o de otra obra importante o considerable, una u otra se arruinaren en todo o en parte, o presentaren evidente peligro de ruina por defecto de construcción o por vicio del suelo, el arquitecto y el empresario son responsables."
In English: if, within ten years from the day the construction of a building or of another major or considerable work was completed, either one collapses in whole or in part, or shows evident danger of collapse due to a construction defect or a defect in the ground, the architect and the contractor are liable.
The compensation claim must be brought within two years from when the ruin occurs or the danger appears. The rule reaches ruin or its evident danger, not any minor defect, and it binds the architect and the contractor of the work. Whether a later buyer can use it directly against the builder or developer depends on the case.
