Property Scams in Spain: 12 Red Flags Every UK Buyer Must Know

Spain is one of the safest property markets in Europe for foreign buyers, with strong legal protections, a well-established notary system, and transparent Land Registry records. But scams do exist — and UK buyers, often unfamiliar with Spanish property law and eager to secure their dream home in the sun, are disproportionately targeted.

The good news: every scam on this list is avoidable with proper due diligence. The bad news: thousands of UK buyers skip due diligence every year, relying on the estate agent's assurances or a recommendation from a friend in the pub. This guide covers the 12 most common red flags, explains how each scam works, and tells you exactly how to protect yourself. For the full buying process, see our step-by-step buying guide.

The 12 Red Flags

1. Property Not on the Land Registry

Every legally built property in Spain should be registered at the Registro de la Propiedad (Land Registry). If a property does not appear on the nota simple — or the nota simple shows a different size, layout, or owner than what you have been told — something is seriously wrong.

How the scam works: The seller claims the property is "being registered" or that registration is "just a formality." In reality, the property may have been built without permission, may be on protected land, or may be subject to a demolition order. Without Land Registry registration, you have no legal proof of ownership and cannot get a mortgage, insure the property, or sell it.

How to protect yourself: Your lawyer should request a nota simple as the very first step in due diligence — before you pay any deposit or sign any document. If the property is not registered, walk away unless your lawyer can confirm a clear path to registration and you are prepared to accept the risk and delay.

2. Illegal Extensions or Builds (PGOU Violations)

This is the single most common problem affecting UK buyers on the Costa del Sol and Costa Blanca. The property you visit has four bedrooms, a converted garage, an enclosed terrace, and a pool. The nota simple shows a two-bedroom apartment with no pool. The extra space was built without planning permission (licencia de obras) and violates the local urban plan (Plan General de Ordenación Urbanística, or PGOU).

How the scam works: The seller (or their agent) presents the property based on its actual built size — including illegal extensions — and prices it accordingly. They may acknowledge the extensions are "not on the deeds" but assure you "everyone does it" and "the town hall never enforces." This is misleading. Illegal builds can face demolition orders (even decades after construction), cannot be insured, and reduce the property's resale value to informed buyers.

How to protect yourself: Compare the nota simple (Land Registry) with the catastro (cadastral registry) and with the actual property. Any discrepancy in square metres is a red flag. Ask your lawyer to check with the local ayuntamiento whether the property has a licencia de primera ocupación and whether any infractions (infracciones urbanísticas) are on file. For rural properties, check whether an AFO certificate has been issued. Factor the risk of illegal builds into your offer price — or walk away.

3. Below-Market Price with Pressure to Act Fast

A property is listed at 20-30% below comparable properties in the area. The agent tells you there are "three other buyers interested" and you need to put down a deposit today or you will lose it. This urgency is designed to prevent you from doing due diligence.

How the scam works: The artificially low price attracts buyers who are then pressured into paying a non-refundable deposit before they have time to instruct a lawyer, check the nota simple, or research the property. Once the deposit is paid, the buyer discovers legal problems — or the "seller" disappears entirely. In less extreme cases, the low price reflects genuine problems (debts, illegal builds, planning issues) that the agent hopes you will not discover until after you have committed.

How to protect yourself: If a price seems too good to be true, it is. Never pay any deposit without your lawyer reviewing the nota simple, catastro, and any contracts first. A legitimate seller will give you 48-72 hours to complete basic checks. If you are told "it is now or never," it should always be never.

4. Seller Wants Cash Payment Outside the Escritura

The seller (or their agent) suggests that part of the purchase price should be paid "in cash" or "outside the escritura" (the public deed signed at the notary). For example, the agreed price is EUR 350,000 but the seller wants only EUR 280,000 declared in the escritura, with EUR 70,000 paid in cash separately.

How the scam works: The seller reduces their capital gains tax liability by under-declaring the sale price. The buyer is told they benefit too, through lower transfer tax (ITP). In reality, the buyer is committing tax fraud (which carries penalties of 50-150% of the underpaid tax plus interest), has no legal proof of paying the full price (making future claims impossible), and will face a higher capital gains tax bill when they sell (because their declared purchase price is artificially low). This practice was common historically but is now actively prosecuted by the Agencia Tributaria.

How to protect yourself: Refuse absolutely. The full purchase price must be declared in the escritura and paid via traceable bank transfer. Any agent or seller who suggests otherwise is asking you to commit a crime. Report the suggestion to your lawyer. For a full breakdown of the taxes involved, see our costs and taxes guide.

5. No Energy Performance Certificate

Since June 2013, every property sold or rented in Spain must have a valid Certificado de Eficiencia Energética (energy performance certificate, or EPC). A seller who cannot or will not provide one may be hiding something — or simply does not have legal paperwork in order.

How the scam works: On its own, a missing EPC is not a scam — it is a legal requirement the seller has failed to meet. But it is often a symptom of broader problems: if the seller has not bothered to get a EUR 100-200 EPC, what other legal requirements have they skipped? Properties without EPCs sometimes lack other essential documents like the licencia de primera ocupación, habitability certificate, or up-to-date IBI (property tax) payments.

How to protect yourself: Require the EPC before signing any contract. If the seller does not have one, they must obtain it at their expense before the sale can complete at the notary. Use the missing EPC as a prompt to verify all other essential documents are in order.

6. Agent Demands Large Upfront Fees

An agent asks you to pay a "reservation fee," "search fee," "finder's fee," or "administration fee" of EUR 3,000-10,000+ before they will show you properties or before you have even identified a specific property to buy.

How the scam works: Legitimate estate agents in Spain are paid by the seller on completion — not by the buyer upfront. Agents who demand large upfront fees from buyers are either running a fee-harvesting operation (collecting fees from multiple buyers with no intention of delivering a service) or padding their income with charges that have no basis in standard practice. Some "property finding" services do charge legitimate fees, but these should be clearly documented, proportionate, and ideally payable on successful completion.

How to protect yourself: Never pay large fees to an agent before you have a signed contract on a specific property. A small holding deposit (EUR 3,000-6,000) on a specific property you have chosen is normal — but this should be documented, held by a lawyer or escrow agent, and refundable if the sale does not proceed. General "search fees" or "reservation fees" not tied to a specific property are a red flag.

7. Title Does Not Match the Seller

The person presenting themselves as the seller is not the person (or entity) listed as the owner on the nota simple. They may claim to be a family member, a representative, or simply the person "handling the sale."

How the scam works: Someone who does not own the property attempts to sell it, either fraudulently or through a genuine but flawed arrangement (expired power of attorney, deceased owner whose estate has not been settled, co-owner selling without the consent of other co-owners). You pay a deposit to someone who cannot legally sell you the property, and recovery is difficult or impossible.

How to protect yourself: Your lawyer must verify that the seller named in the arras contract matches the owner on the nota simple. If a representative is acting on behalf of the owner, they must have a valid, specific poder notarial (notarial power of attorney) for the sale of that specific property. Your lawyer should verify the power of attorney is current, has not been revoked, and authorises the specific transaction.

8. Property Has Outstanding Debts or Embargos

The property has charges registered against it — unpaid mortgages, community fee debts, tax liens, or court-ordered embargos. In Spain, many debts attach to the property, not just the person. If you buy a property with outstanding debts, you may inherit them.

How the scam works: The seller knows about the debts but does not disclose them, hoping the buyer will not check. Or the agent is aware but downplays the issue: "the mortgage will be cancelled at completion" or "the community debts are small." In the worst case, the buyer completes the purchase only to discover a EUR 50,000 mortgage charge, EUR 15,000 in unpaid community fees, or a court embargo that prevents them from selling or mortgaging the property.

How to protect yourself: The nota simple shows all charges registered against the property — mortgages, embargos, and liens. Your lawyer should also contact the community of owners (comunidad de propietarios) to confirm whether the seller is up to date on community fees, and check with the ayuntamiento for outstanding IBI (property tax) debts. All debts must be cleared or deducted from the purchase price at completion, with proof of cancellation.

9. Fake or Misleading Photos and Descriptions

The property listing shows beautiful photos that do not match reality — either because the photos are of a different property, have been heavily edited, or were taken years ago before the property deteriorated. Descriptions may overstate the size, the quality of finishes, or the proximity to amenities.

How the scam works: Misleading listings are designed to get you to visit (or in some cases, to buy sight unseen from the UK). Once you arrive and discover the property does not match the listing, the agent pivots to other properties ("but I have something even better nearby"). In the worst case, buyers purchasing remotely based on photos and video calls discover a completely different property upon arrival.

How to protect yourself: Always visit the property in person before signing any contract or paying any deposit. Compare the listing photos with reality. Check the declared square metres on the catastro against what you see. If buying from the UK, send a trusted representative to view the property or use a video call where you direct the camera (not the agent). Never buy sight unseen.

10. Urbanisation with No Primera Ocupación Licence

You are buying in a residential development (urbanización) where individual properties or the entire development does not have a licencia de primera ocupación (first occupation licence, also called cédula de habitabilidad in some regions). This licence confirms the property was built according to the approved plans and is fit for habitation.

How the scam works: The developer completed the build but either deviated from the approved plans (building extra floors, exceeding permitted density, or encroaching on public land) or failed to complete required infrastructure (roads, sewage, landscaping, communal areas). Without the primera ocupación, residents cannot get permanent utility contracts (only temporary "obra" connections), cannot register on the padrón (municipal register), may have difficulty getting insurance, and the property is worth significantly less on resale.

How to protect yourself: Ask for a copy of the licencia de primera ocupación before signing the arras. If it has not been issued, ask your lawyer to investigate why and whether it is likely to be granted. Do not accept assurances that it is "in process" or "just a formality" — some developments have been waiting 10+ years. Properties without this licence should be priced 20-40% below comparable properties that have it.

11. Off-Plan Developer Without Bank Guarantee

You are buying a property off-plan (sobre plano) from a developer who does not provide a bank guarantee (aval bancario) covering your stage payments. Spanish law (Ley 57/1968, updated by Ley 20/2015) requires developers to guarantee all buyer payments through a bank guarantee or insurance policy.

How the scam works: The developer collects stage payments from buyers without depositing them in a guaranteed account. If the developer goes bankrupt or abandons the project (as happened to thousands of buyers during the 2008-2014 crisis), buyers lose their money with no recourse. Without a bank guarantee, the money is simply gone.

How to protect yourself: Before paying any money to a developer, demand written proof of the bank guarantee (aval bancario) or insurance policy (seguro de caución) covering your payments. The guarantee should name you specifically and cover the full amount of each payment. Your lawyer should verify the guarantee directly with the issuing bank. If the developer cannot or will not provide a bank guarantee, do not pay them a single euro. This is non-negotiable and required by law.

12. Power of Attorney Abuse

You grant a poder notarial (power of attorney) to someone in Spain — often a lawyer, gestor, or agent — to act on your behalf in the purchase. The power of attorney is then used to take actions you did not authorise: signing contracts at different terms, purchasing a different property, or transferring funds to accounts you did not approve.

How the scam works: A general power of attorney (poder general) gives the representative broad authority to act on your behalf in almost any legal matter. An unscrupulous representative can use this to commit fraud — signing documents, moving money, or taking on obligations in your name. Even a specific power of attorney can be abused if it is drafted too broadly.

How to protect yourself: Only grant a specific power of attorney (poder especial) that names the exact property, the exact price, the exact notary, and the exact date. Never grant a general power of attorney for a property transaction. Have the power of attorney drafted by your own lawyer (not the person who will use it). Include an expiry date. Revoke the power of attorney in writing at the same notary immediately after the transaction completes. If possible, attend the notary signing in person — power of attorney should be a last resort, not a convenience.

How to Stay Safe: Due Diligence Is Non-Negotiable

Every red flag on this list is detectable through proper due diligence. Your independent lawyer should check the nota simple, catastro, PGOU compliance, primera ocupación licence, community debts, IBI arrears, seller identity, and energy certificate — all before you sign the arras. For the full 50-point checklist covering legal, structural, plumbing, electrical, and exterior checks, see our complete property inspection checklist.

A EUR 1,500-2,500 legal fee for proper due diligence is the cheapest insurance you will ever buy.

Key Takeaways

• Instruct your own independent lawyer — never use a lawyer recommended by the seller or agent
• Never pay any money without your lawyer reviewing the nota simple, catastro, and contract first
• If you feel pressured to act fast, slow down — urgency is the scammer's primary tool
• Verify everything independently — do not rely on the agent's or seller's assurances about legality, debts, or documentation
• If a price seems too good to be true, it is. Investigate why before committing
• Hold deposits in your lawyer's escrow account, never pay directly to the seller or agent
