The Arras Contract, What Every Buyer Must Know Before Signing

Every property purchase in Spain passes through the same crossroads: the moment when a verbal agreement becomes a binding commitment, and money changes hands for the first time. That moment is the arras contract — and most buyers sign it without fully understanding what they’ve agreed to.

The Spanish property market moves fast, especially on the Costa del Sol. You find the right flat, agree on a price, and within days you’re being asked to sign a private document and transfer a deposit, typically around 10% of the purchase price. The pressure to close quickly is real. And in that rush, buyers often overlook something that matters enormously: what type of arras contract they’re signing.

This isn’t a technical detail. It determines your rights if the deal falls apart — whether you can walk away, whether you can demand enforcement, and what happens to your money. Let me walk you through each type.

What Is a Contrato de Arras?

At its core, an arras contract is a private pre-sale agreement between buyer and seller. The buyer hands over a deposit to reserve the property while both parties prepare for the public deed — the notarial escritura that formally transfers ownership. The contract fixes the agreed price, sets a deadline for signing the deed, and establishes the consequences if either party backs out.

What it is not is simply a receipt. In Spanish law, an arras contract is a legally binding instrument with specific consequences that vary dramatically depending on which of three legal categories it falls into. Choosing the wrong type — or failing to specify one at all — can lead to outcomes that neither party anticipated.

Important: If your contract does not clearly state which type of arras applies, Spanish courts will generally treat it as confirmatorias, the most restrictive category. Silence does not protect you.

The Three Types

Type 1: Arras Confirmatorias — The Firmest Commitment

These are the most binding form. Both parties signal their firm intention to complete the transaction. The deposit is simply an advance payment on the purchase price — it confirms the deal, rather than leaving any door open to walk away.

The key consequence: neither buyer nor seller has an automatic right to withdraw. If someone pulls out, the injured party must seek legal remedy. They can demand specific performance — that is, enforcement of the sale — or claim damages through the courts. There is no clean exit by simply forfeiting or returning the deposit.

If the buyer withdraws, the seller can sue to enforce the sale or claim damages. If the seller withdraws, the buyer has the same options. In both cases, the process goes through the courts.

Best suited for: transactions where both parties are fully committed and financing is already secured. More common in commercial or professional real estate contexts.

Type 2: Arras Penitenciales — The Flexible Exit

These are by far the most common type in Spanish residential property transactions — and the only arras expressly regulated in the Civil Code, under Article 1454. They function as a bilateral exit clause: both parties can withdraw, but at a defined cost.

If the buyer withdraws, they lose the deposit. If the seller withdraws, they must return double the amount received. Neither party needs to justify their decision or seek court approval. The deposit itself is the price of freedom.

This clean, predictable mechanism is what makes arras penitenciales the standard choice for most residential purchases — particularly those involving mortgage financing. That said, they must be paired with a well-drafted mortgage contingency clause.

Best suited for: most residential purchases, especially those involving mortgage financing.

Type 3: Arras Penales — The Reinforced Guarantee

These occupy a middle ground. They function as a pre-agreed penalty clause for breach of contract. If one party fails to complete the transaction, the other is entitled to the deposit — but crucially, they can also pursue the sale itself, or claim additional damages, on top of the penalty.

Unlike penitenciales, arras penales do not give either party a right to simply walk away. The penalty is compensation for breach, not a fee to buy out of the obligation. If you want to guarantee performance rather than just set a financial consequence, this is the stronger instrument.

Best suited for: situations where one party has genuine reason to worry about the other’s commitment, or where the transaction involves a high-value investment property.

The Mortgage Problem — And How to Protect Yourself

The most common scenario where arras contracts go wrong is financing. A buyer signs penitenciales, hands over a 10% deposit, then their bank declines the mortgage. The seller interprets the withdrawal as a voluntary decision and keeps the money. The buyer argues it was not their fault.

Who is right? That depends entirely on one thing: whether the contract included a condición suspensiva — a mortgage contingency clause.

“A single well-drafted clause can be the difference between recovering your deposit in full and losing tens of thousands of euros through no fault of your own.”

A proper mortgage contingency clause should specify the minimum loan amount, the maximum acceptable interest rate, the deadline for obtaining finance, and the documentation required to evidence a formal refusal from the bank. Vague language — “subject to mortgage” in a single line — is routinely challenged and often fails.

At A | Aguilera Legal, we see these disputes more often than most people realise, and almost all of them were entirely avoidable with the right drafting at the pre-contract stage.

What Your Arras Contract Must Include

Whether you are buying a seafront apartment in Marbella or a townhouse in the Málaga historic centre, any arras contract should contain at minimum:

●       Full identification of both parties, including NIE numbers for non-resident buyers

●       A precise legal description of the property, consistent with the Land Registry entry

●       The total agreed purchase price and the amount given as arras

●       A clear statement of which type of arras applies — ideally citing the relevant Civil Code article

●       A deadline for signing the public deed before a notary (60 to 90 days is standard)

●       Confirmation that the property will be delivered free of charges, encumbrances and debts

●       A mortgage contingency clause if financing is involved, with specific conditions and timelines

●       Any agreed conditions on the state of the property, pending works or licences

Documents downloaded from the internet or drafted by estate agents can serve as a starting point, but they are rarely tailored to your specific situation. The cost of having a lawyer review or draft the contract is a fraction of what a dispute can cost you later.

A Final Thought on Risk

Buying property in Spain, particularly from abroad, involves a series of moments where legal certainty matters above everything else. The arras contract is the first of those moments. It is the document that commits you financially and shapes your rights for everything that follows.

My approach at A | Aguilera Legal is not simply to process transactions but to help clients understand what they are signing and why. If you are at the point of making an offer on a property in Málaga or along the Costa del Sol, the right time to get legal advice is before the contract is on the table — not after you’ve already signed it.
