Contrato de Arras: The Most Crucial Step Before Buying Property in Spain
Many expats from the UK or the US mistakenly believe that signing the final deeds at the notary is the decisive moment when buying property in Spain. The brutal legal reality is different: Your fate is sealed weeks earlier with the preliminary contract. The Contrato de Arras is a private legal document that makes the purchase completely binding. We will show you exactly what you need to look out for so that your 10% deposit is safe and you don’t inadvertently accept massive legal disadvantages.
Key Takeaways
Buying real estate in Spain works very differently than in Northern Europe or North America. The Contrato de Arras is not a mere formality; it is a rock-solid contract. We explain the legal differences and how to handle the transaction safely.
Arras Penitenciales vs. Confirmatorias: The Crucial Difference
Before we talk about individual clauses, you must understand Spanish contract law. There is not just “one” Arras contract, but three distinctly different types. If you sign the wrong one, you might not be able to back out of the purchase without facing total financial ruin.
What You Are Actually Signing Legally
The trap: If the specific type is not explicitly stated in the contract, Spanish courts will often assume it is a Confirmatorias contract by default.
- Arras Penitenciales (Highly Recommended): This is the gold standard for a safe property purchase (regulated in Article 1454 of the Spanish Civil Code). It allows both parties to back out of the deal. If you (the buyer) back out, you lose your 10% deposit. If the seller backs out (e.g., because they received a much higher offer), they must legally refund you double your deposit. This ensures a clean break and compensates you for lost time.
- Arras Confirmatorias: Here, the deposit is merely a first installment of the purchase price. The contract is absolutely binding. A simple withdrawal is not permitted; the opposing party can take you to court to force the completion of the sale.
- Arras Penales: These function like a contractual penalty. They secure financial compensation but often still legally force the fulfillment of the actual purchase contract.
The Content: What Must Be in the Contract?
Because there is no official, standardized government form for this preliminary contract in Spain, estate agents or lawyers draft the document themselves. This means: You (or your independent lawyer) must meticulously check whether all protective mechanisms are included.
Your Checklist Before Signing:
Before you transfer a single euro, your lawyer must check the property. The contract must strictly include the cadastral number, the exact purchase price, the deadline for the notary appointment, and the distribution of costs.
- Freedom from Debt: It must be explicitly noted that the property will be handed over “libre de cargas” (free of all charges, debts, and mortgages) at the notary appointment. You must verify this beforehand by pulling the official Nota Simple.
- Deadlines: A clear, absolute maximum date for the final notary appointment (the Escritura). This is usually set 4 to 8 weeks after signing the Arras.
- Cost Distribution: Who pays what? It is standard practice in Spain that the buyer bears the transfer taxes and notary costs, while the seller pays the Plusvalía (municipal capital gains tax).
- Property Data: The exact agreed purchase price and the precise cadastral reference (Referencia Catastral).
Process and Payment: Where Does the 10% Go?
The contract is signed privately – often in the estate agent’s office or even via scanned email copies if you are still back in your home country. The deposit (minus any initial small reservation fee) is usually transferred directly into the seller’s bank account. Alternatively, the money goes into a designated client escrow account held by your law firm.
Strict Warning: Never transfer huge sums of money (like a 10% deposit) into the private bank account of a real estate agent!
Our Expert Tip:
As soon as the Contrato de Arras is signed, the agreed countdown begins (e.g., 60 days). During this exact timeframe, you must liquidate the remaining 90% of the purchase price. Keep in mind that for the final signature, the Spanish notary will almost always demand to see a physically printed, bank-guaranteed cheque (Cheque Bancario). Therefore, you must sort out the opening of your Spanish bank account and the transfer of your funds very early on!
Once the Arras is signed and the deposit is paid, the clock is ticking. You now have 4 to 8 weeks until the final notary appointment. During this time, you must move the rest of your capital to Spain.

Recommendation: Use Wise for Your Deposit Transfer
If you are transferring hundreds of thousands of Pounds or Dollars to Spain, traditional high-street banks will severely penalize you with terrible, hidden exchange rate markups and slow processing times. We always use Wise for these massive property sums because they exchange your money at the true mid-market rate, offer total transparency, and the money often arrives in seconds.
