Off-Plan Bank Guarantees in Spain: How to Protect Your Deposit (Ley 57/68)

When you buy off-plan in Spain, the developer must protect every stage payment with a bank guarantee or insurance policy. If the build isn't finished or licensed, your money is refunded with interest. That protection is now written into the LOE (Ley 38/1999), which absorbed the old Ley 57/1968.

If you lived through the 2008 crash, or read about it, you know why buyers ask this question first. Developers went bust, half-built resorts sat empty, and some buyers lost deposits they never got back. That fear is reasonable, and it's exactly why the law exists. The good news is that the framework protecting your money has been tightened and clarified since then.

Why did off-plan buyers lose money in 2008?

During the boom, buyers paid deposits and staged instalments to developers who, in some cases, never delivered. When those companies became insolvent, the money had often been spent, and buyers found themselves chasing empty shells.

The law requiring guarantees already existed. The problem was enforcement — many developers ignored it, and some banks accepted deposits without checking a guarantee was in place. What changed after the crash was accountability: Spanish courts, up to the Supreme Court, have repeatedly ruled that the bank holding the deposits can be liable when no proper guarantee was issued. Cases are still being decided in buyers' favour today.

What is a bank guarantee, and what does it cover?

A bank guarantee (aval bancario) is a formal, written promise from a bank or insurer that your off-plan payments will be returned if the developer fails to deliver the home as agreed.

"Staged payments" are the instalments you pay during construction rather than all at once. The guarantee is meant to cover each one, from your reservation through to the final pre-completion instalment. If the property isn't built, isn't finished on time, or never receives its licence, you're entitled to your money back plus statutory interest from the date of each payment. You claim against the guarantor — you don't wait for the developer to recover.

What law protects my deposit today?

Here's the part worth getting right, because a lot of older articles still quote only the 1968 rule.

Ley 57/1968 was the original law requiring developers to guarantee advance payments on off-plan homes. It was repealed by Ley 20/2015, and its protections were carried over into the LOE (Ley 38/1999) under Disposición adicional primera (Additional Provision One), generally cited as taking effect on 1 January 2016.

So the protection didn't disappear — it moved house. If you're buying a new off-plan home in Murcia today, the LOE is the framework that applies. Ley 57/1968 still governs contracts signed before that changeover, which is why it keeps appearing in court cases about older developments.

How do the stages and payments work?

• Reservation. A small fee takes the property off the market while contracts are prepared.
• Private purchase contract. You sign and typically pay a deposit (often ~20–30%). From here, guarantees should be in place.
• Staged payments. Further instalments against agreed milestones during construction.
• Completion. The developer obtains the licencia de primera ocupación, you pay the balance and sign the deed before a notary.

A sensible rule: no full purchase contract or price instalment should be signed or paid before the building licence exists. Until then, only a reservation deposit is appropriate.

What should I check before I pay anything?

• The guarantee certificate itself, in your name, showing the exact amount protected.
• Confirmation that each payment is covered, not just the first.
• The name of the guarantor bank or insurer, matching your contract.
• The special account details, so your money goes where the law requires.
• Written milestones and a delivery date in the contract.
• Every receipt and bank-transfer confirmation, kept safely.

Instruct an independent Spanish lawyer, not one recommended solely by the seller. They can verify the guarantor and confirm the paperwork is genuine.

What if a developer won't provide a guarantee?

Treat it as a stop sign. Providing the guarantee is a legal obligation, not a favour. Don't hand over money on a promise that it will follow "once construction starts." Ask for it in writing before you pay, have your lawyer confirm it's valid, and if it doesn't materialise, walk away. A reputable developer will expect this and have the documents ready.

FAQ

Does the guarantee cover my reservation fee too?

It should cover the advance payments you make under the purchase contract. Reservation fees are smaller and handled slightly differently — ask your lawyer to confirm exactly what's protected.

Is my money safe if the developer goes bankrupt?

That's the whole point of the guarantee. If it's properly in place, you claim against the bank or insurer, not the insolvent developer.

How long do I have to make a claim?

Time limits apply and depend on your contract. Don't assume you've missed the window; get advice quickly if a build stalls.

Do these rules apply to resale homes?

No. Guarantees cover advance payments on off-plan and new-build purchases, not completed resale properties.

Is Ley 57/1968 still the law?

For new contracts, the LOE now governs. Ley 57/1968 still applies to older contracts signed before the 2015 change.
