I’ve been house-hunting in Madrid recently, and after viewing a few properties I liked, the agent started urging me to pay a ‘reservation deposit’ to secure the property and stop the seller from showing it to others. As someone new to Spain, I was unfamiliar with the process and felt a bit lost. It took me several days of consulting with a lawyer and experienced friends to finally understand what this ‘reservation deposit’ was all about. I’m writing this post to give a heads-up to others who are also looking for a home: don’t pay this money lightly!

What Exactly Is a Reservation Deposit?
In Spain, the so-called ‘reservation deposit’ actually comes in two main forms with completely different legal implications, so it’s crucial to distinguish between them! One is the Reserva, and the other is the Señal, which is part of a Contrato de Arras. A Reserva is typically a smaller amount, for instance, €3,000 to €6,000, mainly to have the seller temporarily take the property off the market for a few days, giving you time to prepare for the main contract and paperwork. On the other hand, the deposit in an Arras contract is much more formal, usually 10% of the property price, and is strongly legally binding.
Reserva vs. Contrato de Arras
To make it clearer, I’ve created a simple table to compare the two. This is where pitfalls most commonly occur:
| Item | Reserva | Contrato de Arras |
| Amount | Smaller, typically €3,000-€6,000 | Larger, typically 10% of the total property price |
| Legal Standing | Weaker, depends on the specific terms of the written agreement | Strongly legally binding, protected by the Spanish Civil Code |
| Buyer Backs Out | May lose the deposit, depending on the agreement | Will lose the entire deposit |
| Seller Backs Out | Returns the deposit, usually with no extra compensation | Must return double the deposit to the buyer |
| Recommended Scenario | When you are very interested but need a few days to arrange funds or get loan pre-approval | After all due diligence is complete and you are ready to formally proceed with the transaction |
Key Points to Check Before Paying
No matter which type of deposit you are paying, remember, a verbal agreement means nothing! Everything must be in writing. First, clarify the nature of the payment: the document must clearly state whether the money is a Reserva or part of an Arras. Second, check the property’s legal status: ask the agent or seller for an up-to-date property information report (Nota Simple) to confirm there are no liens, debts, or other issues, which is a key part of understanding current Spanish property buying trends. Third, set clear deadlines: the agreement must specify the final deadline for signing the formal Arras contract or the final deed of sale. The handling of these reservation deposits for buying in Spain if the deal falls through due to bank loan issues or problems on the seller’s side must also be clearly stated in black and white.
Buying a house in Spain is a technical process, especially regarding legal procedures. Agents, wanting to close the deal quickly, might pressure you to pay as soon as possible. It’s crucial to stay calm and consult a lawyer about anything you’re unsure of. A friend of mine once paid a €6,000 Reserva without carefully reading the terms. The seller raised the price afterward, and my friend almost lost the deposit, spending months trying to get it back. I hope my experience can help everyone.
