Yes, Spanish law lets you claim for hidden defects discovered after buying a home, but the window to act is short and unforgiving. Under the Código Civil, you can seek a price reduction or even cancel the sale, provided you prove the defect existed before completion and was genuinely undetectable. At the moment you suspect a problem, preserve the evidence, commission an independent pericial report, and notify the seller formally before the clock runs out.
TL;DR: Claims must be filed within six months of property delivery, as courts strictly enforce this deadline regardless of when the defect appears. A defect qualifies as hidden only if it pre-existed the sale, was non-apparent to a reasonable buyer, and significantly affected the property’s habitability or value. Documenting and commissioning a technical report immediately after discovering a defect is crucial, as expert evidence heavily influences court decisions. Repairing or altering the defect before inspection damages legal evidence, making it more difficult to succeed with a claim. Conducting thorough inspections and confirming legal details before signing avoids most hidden defect issues altogether.

A vicio oculto, or hidden defect, is defined by articles 1484 to 1490 of the Código Civil. In plain terms, it is a serious flaw that already existed when you bought the property, was not visible during your viewings, and either makes the home unfit for normal use or would have led you to negotiate a lower price had you known about it, as Legia’s guide to hidden defects explains.
Courts apply three tests together: the defect must pre-date the sale, it must be non-apparent to a reasonably attentive buyer, and it must be serious enough to affect habitability or value. All three need to hold. A cracked tile you spotted on viewing day does not qualify, no matter how annoying it is. Legal commentary is consistent on this distinction: visible defects are vicios aparentes, and sellers generally carry no liability for anything you could reasonably have noticed. Wear and tear from normal use falls outside the regime entirely, which is why a tired kitchen or fading paintwork will never form the basis of a claim.
Some problems hide in plain sight until the first heavy rain or the first time you switch on every appliance at once. The most commonly reported hidden defects in Spanish property claims include:
During viewings, treat certain signs as prompts for a proper inspection rather than a reason to walk away outright: a suspiciously fresh paint job in one isolated area, a musty smell in a ground-floor room, uneven flooring, or a seller reluctant to answer straightforward questions about past repairs. Borderline cases rarely succeed. Minor settlement cracks typical of older Mallorcan fincas, or defects a standard survey would have caught, usually fail the “hidden” test in court.
Suspicion is not evidence. Once you notice something wrong, whether it is a damp patch appearing months after completion or a wiring fault that trips the fuse box weekly, the next moves matter enormously.
A pericial report carries real weight in Spanish courts. Tinsa’s guidance on reclaiming for hidden defects notes that judges rely heavily on expert testimony to establish origin, dating, and cost, since these are technical questions a buyer cannot credibly argue alone. Courts also expect scientific or technical indicators of pre-existence, such as moisture readings or material analysis that dates the damage.
Pro Tip: Never let a contractor patch the defect before the perito has inspected and documented it. Repairing first destroys the physical evidence that proves the problem existed, and weakens your claim before it even starts.
Once you have a solid pericial report, the process moves through negotiation before it ever reaches a courtroom, and most cases never need to go further than a firmly worded letter.
Start with formal notification. A burofax, Spain’s certified postal and delivery-confirmation service, is the standard method because it creates an official, dateable record that the seller received your complaint. Your burofax should include:
Sellers typically respond in one of a few ways: they dispute the claim outright, they commission their own counter-expert (a contraperitaje) to challenge your findings, or they offer a negotiated settlement to avoid litigation. A documented, time-bound repair offer can be a sensible outcome when the sums involved are modest, though you should only accept terms you can verify afterwards.
If negotiation fails, Spanish law gives you two judicial routes. The acción quanti minoris seeks a proportional reduction in the purchase price to reflect the defect’s cost. The acción redhibitoria goes further, asking the court to rescind the sale entirely and return both parties to their pre-contract position. Courts reserve rescission for genuinely serious defects; price reduction is the more common and more achievable remedy in practice. Either action depends heavily on the strength of your pericial evidence, since judges rarely accept a buyer’s word alone.
The single most important number in this entire process is six months. Under article 1490 CC, the standard saneamiento action for hidden defects has a strict caducity period of six months from the date of delivery of the property, not from when you discovered the problem. Courts treat this as a hard cutoff, so informal chats with the seller do not pause the clock.
New-build properties work differently. The Ley de Ordenación de la Edificación (LOE) creates separate warranties: one year for finishing defects, three years for habitability issues like damp or insulation failures, and ten years for structural defects. These regimes run alongside, not instead of, the Civil Code framework.
Auction purchases and sales carrying “vendido tal cual” (sold as-is) clauses significantly limit your recourse, and longer five-year contractual actions may apply only in specific circumstances, so always check your specific contract wording with a lawyer before assuming a deadline applies.
Before spending money on lawyers and experts, run the numbers honestly. A pericial report typically costs several hundred euros depending on complexity, and legal fees add further cost if the seller disputes your claim and forces a contraperitaje.
Industry guidance points to a rough viability threshold: claims tend to make economic sense when repair costs run to roughly 10% of the purchase price or more. Below that, legal and expert costs can eat most of any compensation you win, especially once you factor in the months a court case can take. Weigh negotiation against litigation carefully: a quick, documented repair from a cooperative seller often delivers a better outcome, faster, than a drawn-out claim over a modest sum. Save litigation for defects serious enough to justify the time and expense.
Acting methodically protects both your evidence and your legal position.
Your next steps depend on the seller’s response: a reasonable settlement offer deserves serious consideration, while silence or denial usually means it is time to prepare for the judicial route.
Every claim described above is avoidable with the right groundwork before you sign anything. On Mallorca specifically, that means commissioning an independent survey before completion, not after, and checking the comunidad de propietarios records for unresolved building issues or pending special payments, which can hint at structural problems the seller has not disclosed. Confirming the exact delivery date in writing also matters more than most buyers realise, since it is the trigger for that six-month clock.
International buyers often struggle with the practicalities of commissioning a Spanish-speaking perito or communicating a formal complaint to a local seller. This is precisely where a local buyer adviser earns their keep, coordinating inspections and keeping documentation in order from the outset. Prudence beats litigation every time: a thorough pre-purchase inspection almost always costs less than a legal claim, and it protects your peace of mind from day one.

You can seek a price reduction (acción quanti minoris) or, for serious cases, cancellation of the sale (acción redhibitoria), provided you prove the defect pre-existed the purchase and was not visible at the time.
Common examples include structural damp, foundation movement, non-compliant or concealed electrical wiring, hidden plumbing leaks, roof waterproofing failures, and woodworm damage disguised by cosmetic repairs.
The standard action under article 1490 CC must be brought within six months of the property’s delivery date, a strict caducity period that courts enforce firmly.
A vicio oculto is a serious defect that existed before the sale, was not detectable during a reasonable inspection, and either makes the property unfit for use or would have reduced the price if disclosed.
Most buyers assume a hidden defect claim is primarily a legal fight. It is not. It is a documentation fight, won or lost in the first fortnight after discovery, long before any lawyer sends a letter. The single biggest reason claims collapse is not weak law, it is buyers who repair the damage before a perito ever sees it, or who wait past the six-month mark hoping a seller will do the decent thing.
The conventional advice to “get a lawyer” undersells the real hero of this process: the pericial report. A judge cannot dispute solid technical dating and origin evidence nearly as easily as they can dispute a buyer’s account of events. Spend your money on the expert first, and treat the lawyer as the person who executes a case the perito has already built for you.
There is also a quieter truth worth saying plainly: not every defect deserves a fight. Prudence, and a thorough survey before you ever sign, will save you from most of this entirely.
