Buying Off-Plan Property in Spain — The Risks and the Protections

Buying off-plan — paying for a home that exists only on an architect's drawings — is how a large share of new property in Spain is sold. Done well, it gets you a brand-new home, built to modern energy standards, often with the chance to choose your unit and finishes, with the price spread over the construction period. Done badly, it means handing significant money to a company for something that does not yet exist. Spain learned hard lessons about that during the 2008 crash, and the law that now protects off-plan buyers is genuinely strong — but only for buyers who actually use it. This guide walks through the whole journey in plain English: the legal framework, stage payments and bank guarantees, the developer's contract, delays, snagging, licences, the ten-year structural insurance and, finally, insuring your new home from the day you get the keys.

One note before we start: our guide to the pitfalls of buying property in Spain covers off-plan risk as one item in a twelve-point overview of the whole buying process. This article is the opposite: a single-topic deep dive into every stage of an off-plan purchase, for readers who are actually about to buy one.

What buying off-plan actually means

Buying off-plan (sobre plano) means signing a purchase contract with a developer (promotor) for a home that has not yet been finished — often before construction has even started. Instead of paying the whole price at a notary on completion day, you typically pay in stages: a reservation fee to secure the unit, a larger payment when you sign the private purchase contract, further instalments during the build, and the balance — usually the biggest part, and often funded by a mortgage — when the home is finished, licensed and ready to be handed over at the notary.

It is worth distinguishing two situations that get lumped together. A true off-plan purchase is made months or years before completion, while the building is a hole in the ground or a concrete frame. A key-ready new build is a finished, never-occupied home you can walk around before buying. The second is much closer to a normal purchase; this guide focuses on the first, where the time gap is the source of both the advantages and the risks.

Why do buyers accept that gap? Because off-plan homes are brand new, built to current construction and energy-efficiency standards, sold with a choice of units early in the development, and paid for gradually rather than in one lump. Early buyers in a development may also pay less than those who buy the last units once everything is finished — though that depends entirely on the market, and is never something to count on.

The structural point to understand is this: until completion, you do not own anything. You are a creditor of the developer, holding a contract and receipts. Everything in this guide exists to protect you during that window — and Spanish law does a great deal of the heavy lifting, if you make sure it is applied.

The risks in plain English

Almost every off-plan horror story comes down to a short list of causes, and each has a legal protection or a practical check that addresses it:

• The developer fails before finishing. The classic risk: insolvency mid-build, leaving buyers with receipts and no home. The answer is the legal regime of secured stage payments, explained below.
• The build never starts, or runs very late. Delays are the most common off-plan problem in practice. The law gives you a right to cancel and recover your money with interest if delivery does not happen on time — but the contract wording matters.
• The finished home is not what was promised. Smaller rooms, cheaper materials, a different orientation, a "sea view" that turns out to be a glimpse. The protection is a contract that nails down plans and specification as binding annexes.
• Licensing problems. A development built without the right licences, or that never obtains its first-occupation licence, can leave owners unable to connect utilities normally or facing legal complications. The protection is checking licences before you pay and before you complete.
• Money paid outside the protected structure. Payments made in cash, to the wrong account, or before the legal protections apply can fall outside the guarantee. The rule is simple: every euro goes through the protected route, with paperwork.
• Structural defects appearing years later. Addressed by the LOE's warranty periods and the mandatory ten-year structural insurance, the seguro decenal.
• Market movement. Between contract and completion, prices, mortgage conditions and exchange rates can move against you. No law fixes this one — only prudence: buy what you could still afford if conditions worsened, and if your funds are in another currency, plan for movement in the rate.

The legal framework: the LOE and Ley 20/2015

Two pieces of legislation do most of the work protecting off-plan buyers. The first is Ley 38/1999, de Ordenación de la Edificación (the LOE) — Spain's building act. It defines who is responsible for a building's defects and for how long, requires the ten-year structural insurance on new housing, and — crucially — contains the rules on advance payments to developers.

The second is Ley 20/2015, the insurance-sector law that rewrote the LOE's rules on advance payments with effect from 1 January 2016, replacing a 1968 regime with the modern one described in the next section.

In practice, the framework rests on three pillars:

1. Your stage payments must be secured by a bank guarantee or an insurance policy, and paid into a special account — so if the home is never delivered, you get your money back with interest.
2. Completion is gated by licences and paperwork — the architect's final works certificate, the first-occupation licence, and the registration requirements that stop an uninsured new build entering the Land Registry.
3. After delivery, defects are covered by warranty periods — one, three and ten years depending on the type of defect — backed for the structural risks by compulsory insurance.

Bank guarantees for your stage payments

This is the heart of off-plan buyer protection, so it is worth understanding properly. Under the LOE's first additional provision (as rewritten by Ley 20/2015), a developer who takes payments from buyers before a home is finished must, from the moment the building licence is obtained:

• Secure those payments with either a surety insurance policy (seguro de caución) issued by an authorised insurer, or a bank guarantee (aval bancario) issued by a credit institution. The cover must include the amounts you pay plus legal interest from the date of each payment to the contracted delivery date.
• Pay your money into a special account, separate from any other funds of the developer, used for the construction.

If the construction never starts, or the home is not delivered within the agreed period, you can cancel the contract and demand the return of everything you paid on account — including applicable taxes — increased by legal interest. If the developer cannot or will not pay, you claim against the guarantor: the bank or the insurer. Where the cover is a surety insurance policy, the law requires the insurer to pay out within thirty days of a valid claim once the agreed period has passed without delivery. That is the mechanism that stands between an off-plan buyer and the fate of pre-2008 buyers whose developers simply disappeared with their deposits.

What does this mean for you in practice?

• Ask, before you reserve, how advance payments are protected — which bank or insurer is providing the guarantee, and for the special account details. A professional developer expects the question.
• Get the guarantee document for your own payments. You should receive documentation of the cover protecting the amounts you personally pay. Keep it with your contract — it is what you would claim against.
• Pay only by traceable transfer to the special account. Never in cash, never to an unrelated account, never "to hold the price" outside the contract. Money that bypasses the protected structure is money you may struggle to recover.
• Be careful with money handed over before the building licence exists. The legal obligation to guarantee payments runs from the granting of the building licence. Early "pre-launch" reservations are common and often modest, but your lawyer should confirm how any pre-licence payment is held and what happens to it if the licence is never granted.

Checking the developer and the site

Before any serious money moves, the seller of a home that does not yet exist deserves more scrutiny than the seller of one that does. The checks an independent lawyer runs typically include:

• Who the developer actually is. The company's identity, registration and standing, and its track record — completed developments you can go and look at are worth more than brochures. New single-project companies are common in development and not a red flag in themselves, but they make the payment guarantees even more important.
• That the developer owns the land. A nota simple from the Land Registry — obtainable through the Colegio de Registradores — shows the registered owner of the plot and any charges over it. A development loan secured on the land is normal; your lawyer confirms that the developer's mortgage will be cancelled (or, if you choose, subrogated) for your unit at completion, so you do not buy a home carrying the developer's debt.
• That the building licence has been granted. Not applied for, not "expected imminently" — granted. The licence also marks the point from which the advance-payment protections must be in place.
• The planning status of the land — that it is classified for residential building and the project matches what the licence authorises. Rural-fringe and first-line plots deserve particular care.
• The project documentation — plans, the specification document (memoria de calidades), and the horizontal division for apartment developments, so what you are contracting to buy is precisely identifiable.

If you are new to how Spanish conveyancing roles work — why the notary is not your adviser, and what an independent lawyer does that nobody else in the transaction will — our guide to property lawyers in Spain covers it in detail. For off-plan purchases specifically, the lawyer's role is at its most valuable: there is simply more to verify, and more of it happens before you can see what you are buying. If you would like an introduction to an independent, English-speaking firm, we work alongside Platinum Legal Spain, who act for international buyers across Spain.

The developer's contract, clause by clause

The private purchase contract is where an off-plan purchase is really won or lost. It is drafted by the developer's lawyers, for the developer's benefit, and presented as standard. Much of it is negotiable — and even where it is not, you need to know exactly what you are agreeing to. The points your lawyer examines:

The home itself

• Precise identification of the unit — block, floor, door, orientation, built and usable areas, terraces, parking space and storeroom if included — with the plans annexed to the contract, not merely referenced.
• The specification (memoria de calidades) as a binding annex. This document lists the materials, finishes, kitchen fittings and installations you are paying for. It should be contractual, and any clause allowing the developer to vary materials should be limited to changes of equivalent or better quality, ideally for justified technical reasons only.

The money

• Price with VAT stated separately, and a stage-payment schedule showing exactly what is paid, when, and into which account.
• Express reference to the guarantees covering each advance payment, and the developer's obligation to deliver the guarantee documentation to you.
• Who pays which completion costs. The allocation of notary, registry and administrative costs should be clear and lawful — your lawyer will flag any clause that shifts costs to you improperly.

Time and default

• A real completion date. Not "estimated", not indefinitely extendable. A limited, defined grace period is common; an open-ended one defeats your delay rights.
• What delivery means — completion should be conditional on the architect's final works certificate and the first-occupation licence (or its regional equivalent), not just on the developer declaring the home finished.
• Symmetrical default terms. If you are penalised for late payment, the developer should face consequences for late delivery. Watch for clauses that let the developer cancel cheaply while binding you tightly.
• What happens to your choices and extras. Upgrades and customisations paid during the build should be documented as contract variations, protected like any other advance payment.

None of this is exotic lawyering; it is careful reading before signature, at the one moment you still have leverage. Once you have signed and paid, you have agreed to whatever the contract says.

Delays — your rights when the build runs late

Delay is the most common off-plan complaint, and the law is clearer here than most buyers expect. If the construction does not start, or the home is not delivered, within the period agreed in your contract, the LOE's advance-payment regime gives you a choice:

• Cancel and recover your money. You may rescind the contract and demand the return of every amount paid on account, including applicable taxes, plus legal interest. The claim runs first against the developer and, if necessary, against the guarantor bank or insurer — that is precisely what the guarantee exists for.
• Or agree to wait. If you still want the home, you can grant the developer more time — sensibly, in writing, with a new fixed date and, where you have the leverage, something in return.

Three practical points make the difference between a right on paper and money in your account. First, the contractual date is your anchor — which is why an open-ended completion clause is so damaging. Second, document everything: keep every receipt, guarantee certificate, contract annex and piece of correspondence about the timetable. Third, act promptly and take advice before you move: how and when you claim, and against whom, is exactly the situation in which an hour of a lawyer's time is worth many times its cost. Do not sign anything the developer sends you after a delay — extensions, novations, "updated" contracts — without having it reviewed.

Snagging: inspecting your new home

Shortly before completion, you (or your representative) should inspect the finished home against the contract — the visit Spanish developers usually call the repaso, and British buyers call snagging. It matters more than people think, because your practical leverage is never higher than in the days before you sign the deed and pay the balance.

• Take the paperwork with you. Inspect against the plans and the memoria de calidades: room sizes, orientation, the kitchen and bathroom fittings specified, flooring, carpentry, the terrace, the parking space. You are checking that what was promised is what was built.
• Test everything that moves or flows. Windows, doors, blinds, taps, drains, sockets, light points, air-conditioning pre-installations, water pressure. Look for cracked tiles, poor sealing, paint defects, damp marks.
• Record every defect in writing, with photographs, and have the list acknowledged by the developer with a commitment to remedy. Significant items should be fixed — or their remedy documented — before or at completion.
• Consider a professional snagging survey. For a modest fee, an independent surveyor or architect will catch what a non-specialist misses. On a purchase of this size it is money well spent.

Snagging connects directly to your legal warranties. Under Article 17 of the LOE, the builder answers for defects in finishes for one year from handover; defects in construction elements that breach habitability requirements are covered for three years; and structural defects for ten. The one-year finish liability is backed either by insurance or, very commonly, by the developer retaining 5% of the build cost from the builder. Report post-completion defects in writing as soon as they appear — dated notice is what preserves your position.

The first-occupation licence and habitability

A finished building is not automatically a legally occupiable home. Between the last coat of paint and your completion at the notary sit several documents your lawyer verifies:

• The final works certificate (certificado final de obra) — signed by the project architect and technical architect, certifying the building was completed in accordance with the project.
• The first-occupation licence (licencia de primera ocupación) — the town hall's confirmation that the building matches the licence it was granted and is fit for occupation. In a number of regions this step now works through a declaración responsable (a formal declaration filed with the council) rather than a traditional licence, but the substance is the same: municipal-level confirmation that the home may lawfully be occupied. In practice you need it to contract water and electricity in your own name on normal terms.
• The habitability certificate (cédula de habitabilidad) — required in some autonomous communities as a separate document; your lawyer will confirm what applies where you are buying.
• The new-build declaration and division. The development's escritura de obra nueva (new-build deed) and, for apartments, the horizontal division must be properly registered. Here the law gives buyers a quiet but powerful safeguard: under Article 20 of the LOE, notaries may not authorise — and land registrars may not register — new-build declaration deeds for housing unless the mandatory ten-year insurance is accredited. An uninsured new home hits a wall before it can enter the Registry.
• Catastro. The new home must also end up correctly described in the cadastre — Spain's property database, consultable through the Sede Electrónica del Catastro — which matters later for local property tax and for the reference values used in tax calculations.

The golden rule: do not complete without the occupation paperwork in place, however keen you are to get the keys, unless your own lawyer has examined the specific situation and advised you in writing about the consequences. A developer pressing buyers to complete "now, licence to follow" is asking you to give up your strongest lever for nothing.

The seguro decenal — the ten-year structural safety net

Every new residential building in Spain must be covered by ten-year damage insurance — the seguro decenal — before its new-build deed can be registered. It is worth understanding what this policy is, and just as importantly what it is not.

Key facts about the decenal, all set out in Articles 17 and 19 and the second additional provision of the LOE:

• It is compulsory for buildings whose main use is housing, and has been since the LOE came into force.
• It is taken out by the developer but protects the building and its successive owners — if you sell within the ten years, the cover follows the property.
• The sum insured is 100% of the final cost of the material execution of the works, and any policy excess for the ten-year (and three-year) cover cannot exceed 1% of the insured capital.
• One exception exists: an individual self-builder (autopromotor) constructing a single family home for their own use is not obliged to take out the decenal. But if that person sells within the ten-year period, they are required to contract cover for the remaining time — unless the buyer expressly waives it. If you are ever offered a nearly-new self-built villa "without decenal, but you can waive it", understand what you would be giving up: the structural safety net, and potentially complications for your mortgage and your own future resale. Take legal advice before waiving anything.

And the crucial limitation: the seguro decenal is not home insurance. It responds to serious structural damage from construction defects — not to fire, storms, floods, theft, water leaks, broken glass, liability to neighbours or anything happening to your belongings. A brand-new home with a decade of structural cover still needs its own buildings and contents policy from day one, which is where we come back in below.

Completing the purchase: notary, taxes, registration

Once the home is finished and licensed, completion works like any Spanish purchase: the public deed of sale is signed before a notary — an impartial public official, as Spain's Consejo General del Notariado describes the role, rather than an adviser for either side — you pay the balance, and you receive the keys. You will need your NIE number long before this point, since it is required for the contract, the taxes and the deed.

On tax, the essential point is that a new home from a developer is not taxed like a resale. Instead of transfer tax (ITP), you pay VAT (IVA), generally at 10% on homes, plus stamp duty (AJD), which is set by each autonomous community. VAT is paid on your stage payments as you make them, not only at completion — one more reason every payment needs proper invoices and receipts. Notary, registry and administrative fees come on top, as does the cost of your mortgage if you use one — our guides to property purchase taxes and buying costs and mortgages in Spain break down the numbers properly.

After signing, the purchase taxes are filed and the deed is registered at the Land Registry — the step that makes your ownership fully effective against third parties. Your lawyer or their gestoría handles both, along with utility contracts, which for a first occupier means new supply contracts using the home's technical certificates and the occupation paperwork discussed above.

Insuring a brand-new home from day one

From the moment you sign and take the keys, the home is your responsibility. Brand-new properties are, happily, straightforward to insure — everything is new, installations meet current regulations, and insurers price that accordingly — but there are specifics worth knowing, which we cover in depth in our dedicated guide to new-build home insurance in Spain:

• Start cover on completion day. Arrange the policy in advance so it begins the day you get the keys — that way cover is in place from your first hour of ownership rather than being sorted out afterwards. If you buy with a Spanish mortgage, the lender will normally require buildings insurance to be in place at completion in any case.
• Buildings and contents are separate decisions. Buildings (continente) covers the structure and fixed installations; contents (contenido) covers what you bring in — which, for a new home, often arrives in stages. Set the contents sum realistically once furnished, and update it after the big deliveries.
• In an apartment building, the community policy is not enough. The community of owners insures common elements, but your own policy covers your private elements, your improvements, your contents and your personal liability. The two are designed to work together, not to substitute each other.
• Extraordinary risks are handled the Spanish way. Events such as extraordinary flooding are covered through the Consorcio de Compensación de Seguros, the public compensation scheme funded by a small surcharge on Spanish policies — one of the quiet strengths of insuring a home here, and it applies from the moment you have a policy in force.
• Tell the insurer it is a new build. Construction year, materials and security measures all feed the price, and a just-delivered home generally works in your favour.
• The decenal and your home policy do different jobs. If structural damage from a building defect appears, the route is the developer's decenal; if a pipe floods your kitchen or a storm strips the pergola, the route is your own policy. Keep both sets of documents from day one.

The off-plan buyer's checklist

• Instruct an independent lawyer — never the developer's — before paying anything at all.
• Verify the developer's identity, track record and ownership of the plot (nota simple).
• Confirm the building licence is granted, not merely applied for.
• Confirm how advance payments are protected: bank guarantee or surety insurance, plus the special account — and obtain the guarantee documentation for your own payments.
• Have the contract reviewed before signing: plans and specification as binding annexes, a real completion date, delivery conditional on the occupation licence, symmetrical default terms.
• Pay only by traceable transfer to the special account, and keep every receipt and certificate.
• Apply for your NIE early and plan the tax budget — VAT plus stamp duty, not transfer tax.
• Snag the home before completion, in writing, ideally with a professional survey.
• Complete only with the final works certificate and first-occupation licence (or regional equivalent) verified.
• Check the seguro decenal is in place — it is required before the new-build deed can be registered.
• Arrange buildings and contents insurance to start on the day of key handover.
• Keep a complete file: contract, annexes, receipts, guarantees, licences, insurance — for the next ten years.
