The Contrato de Arras in Spain: 5 Clauses That Protect Foreign Buyers

You found the apartment. The agent slides a two-page contract across the table and asks for a 10% deposit today, in cash-transfer terms. Sign here, they say. This is the contrato de arras, and it is the single most dangerous document most foreign buyers sign in Spain, because they sign it without reading it properly.

Here is the uncomfortable truth: by the time you reach the notary, the deal is already decided. The arras contract is where the real negotiation happens, where the money is committed, and where a badly drafted clause can cost you your entire 10% deposit. This article breaks down the five clauses that actually protect you, with the specifics that matter when you are buying from abroad.

What the Contrato de Arras Really Is (And Why It Is Not Just a Formality)

The contrato de arras is a private preliminary agreement signed between buyer and seller before the final deed. It fixes the price, sets a deadline for signing at the notary, and, crucially, requires the buyer to pay a deposit, usually 10% of the purchase price.

Most buyers treat it as a booking form. It is not. It is a binding contract with real financial consequences.

There are three legal types under Spanish law, and the difference decides what happens if the deal collapses:

• Arras penitenciales (Article 1454 Civil Code): either party can walk away. If the buyer backs out, they lose the deposit. If the seller backs out, they pay back double. This is the standard and the safest for you.
• Arras confirmatorias: the deposit simply confirms the sale. Backing out can force the other party to demand full completion or damages. Far riskier.
• Arras penales: the deposit works as a penalty, but the sale can still be enforced.

If your contract does not explicitly say arras penitenciales, you do not have the clean right to walk away by forfeiting your deposit. That is clause number one, and we get there in a moment.

Before you sign anything, it helps to understand the full journey. Our ultimate guide to buying an apartment in Madrid maps out every step, and the pillar guide on buying property in Spain as a foreigner covers the legal framework in depth.

Clause 1: Name the Deposit "Arras Penitenciales" in Writing

This is the clause that gives you an exit. Under arras penitenciales, if your mortgage falls through, if you change your mind, if life gets in the way, your maximum loss is the deposit you paid. Nothing more. No lawsuit forcing you to complete, no claim for extra damages.

What to check:

• The contract must cite Article 1454 of the Civil Code or use the exact term arras penitenciales.
• It must state that the buyer forfeits the deposit if they withdraw, and the seller returns double if they withdraw.
• Vague wording like "señal" or "reserva" without legal qualification is a red flag. Ask your lawyer to rewrite it.

Why this matters for foreign buyers specifically: you are often signing remotely, sometimes without full financing confirmed, sometimes without your NIE yet in hand. Arras penitenciales caps your downside to a known number. Without it, you could be sued for specific performance in a Spanish court while living in Paris or Lyon.

This single clause is why we always review the arras before a client transfers a euro. It is the difference between a controlled risk and an open-ended one.

Clause 2: A Financing Condition (Condición Suspensiva por Financiación)

Here is where most foreign buyers get burned. You sign the arras, pay 10%, then your Spanish bank rejects the mortgage or offers 60% loan-to-value instead of the 70% you expected. Without a financing clause, you have two options: find the missing cash within weeks, or lose your deposit.

A financing suspensive condition solves this. It states that if you cannot obtain a mortgage under agreed terms by a set date, the contract is cancelled and your deposit is returned in full.

A well-drafted financing clause specifies:

• The loan amount you need (for example, 70% of the purchase price).
• The maximum interest rate you are willing to accept.
• A clear deadline to obtain the mortgage offer, with proof required (a bank rejection letter).

Non-residents typically get 60-70% financing in Spain versus 80% for residents, and the process takes longer because banks scrutinize foreign income. Run the numbers first with our mortgage simulator, and read our detailed guide on financing a Madrid purchase as a foreign buyer before you commit to a completion date.

Sellers in hot areas like Salamanca or Chamberí sometimes resist this clause. That is negotiable. A shorter deadline or a slightly higher deposit can persuade them while keeping your protection intact.

Clause 3: A Realistic Completion Deadline You Control

The arras sets the date by which you must sign the final deed at the notary. Miss it, and you can lose your deposit. Foreign buyers underestimate how long the paperwork takes.

Before the notary, you need:

• Your NIE (foreigner identification number), which can take weeks if you apply from abroad. Our complete NIE guide and this investor's guide to getting your NIE explain the realistic timelines.
• A Spanish bank account to move funds and issue the banker's cheque at signing. See our guide to opening a Spanish bank account as a non-resident.
• Your mortgage approval finalized, which the bank must coordinate with its own notary requirements.

A safe completion window for a foreign buyer is usually 45 to 60 days, not the 30 that a seller might push. Build in buffer. Also confirm who chooses the notary and who pays which costs.

Protect yourself further by adding that delays caused by the seller (missing documents, unresolved debts, pending inheritance) do not count against your deadline. This keeps the pressure where it belongs.

Clause 4: Property Delivered Free of Charges, Debts and Tenants

You are buying the apartment, not its problems. This clause guarantees the property arrives free of encumbrances: no outstanding mortgage, no unpaid community fees, no back taxes, no sitting tenant.

Specific items to demand in writing:

• The property is free of any mortgage or lien, or the existing one will be cancelled at or before completion.
• Community fees (comunidad) are paid up to date, with a certificate from the administrator.
• IBI (the annual property tax) is settled, and the last receipt is provided.
• No occupants or tenancy agreements remain in place at handover.
• Any derrama (special building levy voted by the community) is disclosed and assigned to the seller.

Unpaid community debts can legally follow the property to the new owner for the current year plus the previous three. That is a real bill you could inherit. This clause, backed by an up-to-date certificate, closes the gap.

This is exactly the kind of due diligence that separates a supported purchase from a risky one. It is why working with a dedicated buying service matters, and why so many common foreign investor mistakes in Spain trace back to a weak arras contract.

Clause 5: Deposit Held Safely and Costs Clearly Split

Where does your 10% go? In many arras contracts, it goes straight to the seller. If the seller disappears or the deal sours, recovering it means a Spanish lawsuit. Better options exist.

Protection points to negotiate:

• Where possible, have the deposit held by a lawyer's escrow account or a neutral third party rather than paid directly to the seller.
• Specify the exact bank account and require a signed receipt.
• Confirm the deposit is deducted from the final price, not additional to it.

The arras should also spell out who pays what at completion. In Spain, the buyer typically covers:

• ITP (transfer tax on resale homes), which in the Madrid region is 6%, one of the lowest in Spain. New-build homes carry 10% IVA plus stamp duty instead.
• Notary and Land Registry fees, roughly 0.5-1% combined.
• Legal fees, usually 1-1.5%.

Budget around 10-12% on top of the price in total. Get a precise figure with our purchase-cost simulator, and read the full breakdown in our guide to buying costs in Spain and this article on Madrid property purchase costs in 2026.

The arras should confirm the seller bears their own costs: the plusvalía municipal (local capital gains on land value) and, for non-resident sellers, the 3% retention covered in our guide to selling a Madrid apartment as a non-resident.

The Mistake That Costs Foreign Buyers Their Deposit

The single biggest error is signing the arras before a lawyer reviews it. Agents represent the seller in most transactions. The template they hand you is drafted to protect the seller, not you.

A quick real example. A French buyer reserves a two-bed in Retiro at 6,200 EUR per square meter, pays 42,000 EUR as arras, no financing clause. The bank approves only 60% instead of 70%. The buyer cannot cover the gap in time and forfeits the entire deposit. A five-line financing condition would have returned every euro.

Don't sign under pressure. Any legitimate seller gives you 48 hours to have the contract checked. If they refuse, that tells you something.

Frequently Asked Questions

How much is the deposit in a contrato de arras?

The standard deposit is 10% of the purchase price, though it can be negotiated slightly lower or higher. It is deducted from the final price at completion, so it is part of your budget, not an extra cost. Make sure the contract states this deduction explicitly.

Can I recover my arras deposit if my mortgage is refused?

Only if the contract includes a financing suspensive condition (condición suspensiva por financiación). Without it, a refused mortgage does not automatically release you, and you risk losing the deposit. Always insist on this clause, with a clear loan amount, rate and deadline.

What happens if the seller backs out?

Under arras penitenciales, the seller must return double the deposit you paid. If your contract is a different type of arras, the seller could instead be forced to complete or face a damages claim, which is slower and messier. Confirm the contract cites Article 1454 of the Civil Code.

Do I need my NIE before signing the arras?

Not always to sign the arras itself, but you need it to complete at the notary and to open a Spanish bank account. Since NIE processing can take weeks from abroad, start it immediately and build a realistic completion deadline into the contract.

Should a lawyer review the arras before I sign?

Yes, always. The template usually protects the seller, and small wording changes decide whether you can walk away or lose 10%. A lawyer or buyer's agent should check the arras type, financing clause, deadline, encumbrance guarantees and deposit handling before you transfer any money.

Who chooses the notary and pays the fees?

In Spain the buyer generally chooses the notary and pays notary and registry fees, roughly 0.5-1% combined. The arras should state this clearly so there are no surprises at signing. The seller pays the plusvalía municipal and, if non-resident, faces the 3% retention.
