Hi everyone, I’ve just finished the process of buying a house and can finally catch my breath. I found the most crucial and often daunting first step is signing the infamous ‘deposit agreement’—Contrato de Arras. I’ve seen many people in forums asking about this, so I’ve compiled my notes and experience to share, hoping it can help others on their property-buying journey.
What is a Contrato de Arras?
Simply put, it’s not the final purchase contract but a private, legally binding reservation agreement. You pay a deposit, the seller reserves the property for you, and both parties agree to sign the final deed at a notary’s office by a future date. Don’t underestimate this document; once signed, the rights and obligations of both the buyer and seller are locked in. Therefore, make sure you read every clause carefully before signing, or you might regret it later!
The Three Types of Arras
The most confusing part is that there are several types of Arras, each with completely different legal implications. Most real estate agents will default to the first type, but understanding the differences between them is crucial, as detailed in these Spanish property purchase contracts. It directly affects the consequences if one party defaults. I’ve created a simple table to help you understand:
| Type | Key Feature | Consequence of Default |
| Arras Penitenciales | The most common type; allows either party to unilaterally withdraw from the contract. | If the buyer backs out, they lose the entire deposit. If the seller backs out, they must return double the deposit. |
| Arras Confirmatorias | Acts as a down payment, confirming the seriousness of the transaction. | Neither party can unilaterally withdraw. If one party defaults, the other can go to court to demand specific performance (i.e., force the sale). |
| Arras Penales | Functions as a penalty clause. | The defaulting party must forfeit the deposit as a penalty outlined in the arras agreement, and the non-defaulting party can still demand specific performance or claim additional damages. |

Key Information to Verify Before Signing the Arras
Before you sign, go through the document and check every single item—don’t miss anything!
- Party Information: Full names, NIE/DNI numbers, and addresses of both the buyer and seller. Make sure they are accurate.
- Property Details: The exact address of the property, its land registry number (número de finca registral), size, and any included annexes (e.g., storage room, parking space).
- Price and Deposit: The total purchase price and the amount of the deposit you are paying. It should be clearly stated that the deposit is part of the total price.
- Completion Date: There must be a clear deadline for signing the final deed at the notary. If you need to apply for a mortgage, make sure to allow ample time.
- Cost Allocation: Specify who will pay the notary fees, registry fees, Property Transfer Tax (ITP), and Plusvalía tax. While there are common practices, it’s best to have it in black and white.
- Other Clauses: Ensure the property is delivered
with tenants tenant-free and free of charges or liens. Any agreements regarding the property, such as whether appliances are included, should be specified here.
The Contrato de Arras is the most critical legal document in the home-buying process, as it sets the framework for the entire transaction. I highly recommend spending a few hundred euros to have a lawyer review it before you sign. It can save you from significant risks and trouble down the road.
