A new home in Spain comes with more legal protection than most buyers realise. From the snagging list at handover to a ten-year guarantee against structural failure, the law makes the developer answerable for defects long after you collect the keys. Here is what you are entitled to, how long you have to act, and how to make a claim that sticks.
When you buy a new build in Spain, two separate kinds of problem can show up, and the law treats them very differently. The first is snagging: the punch-list of small finish faults you find when the property is handed over — a door that does not close, a chip in the tiling, a tap that drips, paintwork that has been rushed, a missing cupboard. These are minor, cosmetic, and expected. No new building is perfect, and the right time to deal with them is at handover, before you accept the keys and sign off on the property.
The second is a defect in the legal sense — a fault in the construction itself that breaches the standard the developer was obliged to build to. Damp coming through a wall, an electrical installation that does not work, cracks that signal a structural problem, inadequate insulation, water ingress through the roof. These are not snagging; they engage the developer's statutory liability under Spain's Building Act, and the law gives you guarantees of one, three and ten years to pursue them depending on how serious they are. Confusing the two is where buyers lose money: treating a real construction defect as a snag to be patched over can mean missing the moment to make a proper claim.
Spain's Building Act sets out a structured guarantee that follows the property, not just the first buyer.
The framework that governs all of this is the Ley de Ordenación de la Edificación — the Building Act, Law 38/1999, usually shortened to the LOE. It applies to the construction of new buildings and to substantial works on existing ones, and it does something unusual and valuable: it imposes liability on the people who built your home by law, regardless of what the contract says. You cannot be made to sign that liability away in a purchase contract, and in most cases the guarantee passes to later owners too, so a buyer who acquires the property within the guarantee period inherits the protection.
The LOE divides defects into three categories by how serious they are, and attaches a different guarantee period to each. The clock for all three runs from the date the works are received and certified as complete — the acta de recepción — which is broadly the point the building is finished and handed over, not the date you personally bought. Understanding which tier a given problem falls into is the single most important thing, because it decides how long you have, who you can pursue, and what you have to prove. The tiers are set out below.
One of the most useful features of the LOE for a buyer is that it does not point at a single defendant. Liability for construction defects is spread across the chain of people who designed and built the property — and, importantly, it can be joint and several, meaning you may be able to pursue any one of them for the whole loss rather than having to sue each for their share. The developer or promoter (the promotor) is liable to buyers in all cases, which matters because they are usually the party with whom you have a contract and the easiest to identify. Beyond the developer, liability can reach the building contractor, the project architect and the technical architect or other technicians, depending on the nature of the fault.
In principle the LOE tries to attribute each defect to whoever caused it — a design flaw to the architect, a workmanship failure to the contractor, a materials problem to whoever specified or supplied them. But where it cannot be cleanly apportioned, or where one party has disappeared, the joint-and-several rule lets the loss fall on the others. For a foreign buyer this is genuinely protective: you are not left chasing a builder who has dissolved if the developer or a technician remains answerable. Establishing who to pursue, and proving the cause, is exactly where an expert report and proper legal representation earn their keep.
Behind the people who built your home sits compulsory insurance, designed so that a claim does not collapse if a company does.
The LOE does not just say who is liable — it requires that liability to be backed by financial guarantees, so that buyers are not left with a worthless judgment against an insolvent builder. For residential building, the developer is obliged to take out insurance covering the relevant defect liability, most significantly a ten-year structural damage policy (commonly referred to as the seguro decenal) that responds to serious structural failure. There are also mechanisms intended to cover the shorter guarantee tiers. The practical effect is that when a covered defect appears, there may be an insurer standing behind the developer that can be brought into the claim.
This is one of the reasons it is worth taking proper advice rather than simply complaining to the developer and hoping. A well-run defect claim identifies not only every potentially liable party but also the insurance behind them, and is framed so that the insurer can be required to respond. We pursue defect claims against developers and, where appropriate, their insurers, precisely so that a buyer's right to compensation does not depend on the developer's continued existence or willingness to put things right.
The single most valuable thing you can do to protect yourself is to record the property's condition properly at handover, before you accept the keys and certainly before you sign the escritura of purchase or take possession. Walk the property — ideally with a surveyor or technician — and produce a written snagging list of every fault, supported by dated photographs. Doors, windows, taps, drains, electrics, tiling, paintwork, fittings, the working of every installation: it should all be checked and logged. The list is then put to the developer in writing so there is a clear record of what was wrong and when, with a request that the items are remedied.
This matters for two reasons. First, it gives you leverage at the one moment the developer is most motivated to put things right — before completion. Second, and more importantly, it creates contemporaneous evidence. If a finish defect or an installation problem later turns into a dispute, a dated, photographed list handed over at the point of delivery is far stronger than a recollection months afterwards. Some defects — particularly damp and structural movement — only reveal themselves over time and cannot be caught at handover, which is exactly why the multi-year LOE guarantees exist behind the snagging list. But everything that can be seen on day one should be recorded on day one. This is the same diligence we build into a purchase as part of broader property due diligence, and it sits alongside the protections you negotiate when buying a new build.
There are two separate timing rules in a defect claim, and missing either can be fatal. The first is the guarantee period itself — one, three or ten years from completion, depending on the tier. The defect has to appear within that window to be covered at all. A finish defect that shows up after a year, or a habitability problem that emerges after three, falls outside the relevant LOE guarantee, although other contractual or general civil-law routes may sometimes still be available depending on the facts.
The second clock is the limitation period to bring the claim once the defect has appeared. The LOE provides a separate, much shorter period — counted from the moment the damage becomes apparent — within which you must actually pursue the claim. This is why "wait and see" is the most expensive strategy: a buyer who notices damp, hopes it will dry out, and does nothing for a long time can find that the guarantee still covers the type of defect but that the time to claim has quietly run out. The safe response to any suspected defect is to record it, report it in writing and take advice promptly, so that neither clock catches you out. Where a defect overlaps with a contractual breach by the developer, the analysis can be more involved, which is another reason to get the position checked rather than assumed.
Across new builds bought by foreign buyers in Spain, the same problems recur. Recognising them — and knowing which guarantee tier they tend to fall into — helps you act before a clock runs out.
New-build defect liability is one of those areas where Spanish law is genuinely on the buyer's side — but only if the buyer knows the protection exists and acts within the windows the LOE sets. For a foreign owner who is not living in the property full-time, or who assumes a new home will not have problems, the risk is not that the law is weak but that the moment to use it passes unnoticed. A defect appears, the owner mentions it to the developer, nothing happens, and by the time it is taken seriously the limitation clock has run.
Our role is to make sure that does not happen. We advise on the snagging process at handover so the property's condition is properly recorded before you accept it; we assess whether a problem is a snag or a genuine defect, and which guarantee tier it falls into; and we pursue defect claims against developers and their insurers — coordinating the expert report, serving the formal demand, and litigating where negotiation fails. We work with bar-registered solicitors and legal specialists, we act for English-speaking clients across Spain, and we explain every step in plain English. We quote for the work involved in a claim rather than leave you guessing, and we will tell you honestly when a claim is worth pursuing and when it is not. Extras may apply depending on the complexity of the matter and the expert evidence required.
Snagging is the punch-list of minor, cosmetic finish faults you record at handover — a door that does not close, chipped tiling, rushed paintwork. A defect in the legal sense is a fault in the construction itself that breaches the standard the developer had to build to, such as damp, faulty installations or structural problems. Defects engage the developer's statutory liability under the LOE, with guarantee periods of one, three or ten years depending on seriousness.
Under the Building Act (LOE, Law 38/1999), defects in finishes carry a one-year guarantee, defects affecting habitability — such as damp, plumbing, electrics and insulation — carry a three-year guarantee, and defects affecting the structural stability and safety of the building carry a ten-year guarantee. The periods run from when the works were received and certified as complete.
The one, three and ten-year periods run from the date the works are received and certified as complete — broadly when the building is finished and handed over — not from the date you personally bought. In most cases the guarantee passes with the property, so a buyer who acquires within the period inherits the protection.
Liability is spread across the chain that designed and built the property. The developer or promoter is liable to buyers in all cases, and liability can also reach the building contractor, the project architect and the technical architect, depending on the fault. Crucially it can be joint and several, so you may be able to pursue one party for the whole loss if others have disappeared.
The LOE requires the developer's defect liability to be backed by financial guarantees, most significantly a ten-year structural damage policy (the seguro decenal) that responds to serious structural failure, with mechanisms intended to cover the shorter tiers too. This means that when a covered defect appears, there may be an insurer standing behind the developer that can be brought into the claim.
There are two clocks. The defect must appear within the relevant guarantee period — one, three or ten years from completion. Once it appears, a separate and much shorter limitation period begins for actually bringing the claim, counted from when the damage becomes apparent. This is why you should record and report any suspected defect promptly rather than wait and see.
The usual sequence is: report the defect to the developer in writing by a method that proves date and delivery; obtain an independent expert report (peritaje) identifying the defect, its cause and the cost to remedy; serve a formal legal demand on the developer, any other liable party and the insurer; and, if that fails, bring court proceedings. Many claims resolve before court once a strong expert report is on the table.
A peritaje is an independent technical expert's report. The expert inspects the property and sets out what the defect is, what caused it, which LOE guarantee tier it falls into, who is responsible and the cost of putting it right. It is the backbone of a defect claim and the evidence a court relies on, so obtaining it early — while the defect is visible — is critical.
The recurring ones are damp and water penetration, plumbing and drainage faults, electrical installation defects, inadequate insulation or soundproofing, and structural cracking or movement. The first four typically fall within the three-year habitability guarantee; structural problems fall within the ten-year tier. Finish faults are usually one-year matters and overlap with the handover snagging list.
Often, yes. Because liability under the LOE can be joint and several, you may be able to pursue the contractor, architect or technical architect even if the developer no longer exists. The mandatory insurance behind the construction also means an insurer may respond. Identifying every potentially liable party and the relevant policy early is part of building a claim that does not depend on one company surviving.
From the snagging list at handover to a structural claim years later, the law makes the developer answerable — but only if you act in time. We assess the position, build the evidence, and pursue developers and their insurers. In plain English, across Spain.
