After being overwhelmed by house viewings, I finally found an apartment I loved, and the agent immediately pushed for me to sign a document called the Contrato de Arras, which is a deposit agreement. At first, I thought it was just a simple deposit and was ready to sign, but after some research, I realized there’s a lot more to the deposit for buying property in Spain! If you don’t get it right, your deposit of thousands or even tens of thousands of euros could be lost. Today, I’m sharing my research to help others on their home-buying journey.
What Exactly is a Deposit Agreement?
Simply put, this contract is a written commitment between the buyer and seller. As the buyer, you pay a deposit, and the seller promises not to sell the property to anyone else within an agreed timeframe and to keep the price fixed. It’s not the final property deed transfer contract, but it is legally binding and a crucial part of the entire home-buying process.

The Most Crucial Step: Understanding the Three Types of Arras
Spanish deposit agreements mainly fall into three categories, each with completely different legal consequences. Before signing, it is essential to confirm with your lawyer which type it is!
| Contract Type | Key Features | Consequences of Breach |
| Arras Penitenciales | The most common type; allows either party to back out. | If the buyer backs out, the deposit is forfeited. If the seller backs out, they must pay double the deposit back. |
| Arras Confirmatorias | Confirms the sale; acts as an advance payment on the final contract. | Neither party can unilaterally withdraw. The other party can sue for specific performance (force the sale) or claim damages. |
| Arras Penales | Acts as a penalty clause. | The defaulting party must pay the agreed-upon penalty, but this doesn’t automatically terminate the contract. The non-defaulting party can still demand the completion of the sale. |
Most real estate agencies offer the first type, Arras Penitenciales, because it’s the most straightforward. Regardless, it’s always wise to read the clauses carefully.
Before You Sign, Double-Check These Points!
Don’t rush into signing just because you’re excited! Before you put pen to paper, I recommend you carefully verify the following:
- Property Details: Ensure they perfectly match the information on the Land Registry report (Nota Simple), especially the address, size, and whether the property is free of any debts or encumbrances, a crucial verification step in the process of paying a deposit for a Spanish property.
- Party Identification: The personal details of both buyer and seller must be accurate. If the sellers are a married couple, both typically need to sign.
- Price and Deposit: The total purchase price, the deposit amount, the payment method, and the payment deadline must all be clearly stated.
- Completion Deadline: Set a clear and mutually agreeable deadline for the final signing of the deed (escritura).
- Cost Allocation: Clearly specify who is responsible for agency fees, notary fees, taxes, etc. Although there are common practices, it’s safest to have it in writing in the contract.
- Additional Clauses: For instance, whether furniture and appliances are included in the price, the condition of the property upon handover, etc.
The Contrato de Arras is a vital document that protects the rights of both the buyer and the seller. While hiring a lawyer adds an expense, it’s absolutely worth it compared to the risk of losing a substantial deposit. In my case, my lawyer spotted an ambiguous clause about the handover date, which saved me from major trouble later on. I hope everyone’s home-buying journey goes smoothly!
