What is a deposit agreement and what is its legal validity?

In real estate law, a deposit agreement is a contract signed between buyer and seller in which the purchasing party advances a sum of money as a guarantee. Although the expression "deposit contract" is often used generically, in strict legal terms it is not an independent contract type, but an ancillary agreement usually integrated into a preparatory contract or promise of sale.

The Civil Code explicitly regulates the scope of these cash payments, although Supreme Court case law has refined its application over the years. Spanish judicial doctrine has consistently established that the mere payment of a sum of money does not automatically grant the right to withdraw from the deal by forfeiting or returning that amount. Depending on the clauses set out in the document, the deposit can serve as a simple advance payment, a reservation with the option to terminate, or a penalty clause for delay and default.

For this reason, when the parties do not specify in the wording which precise modality they are agreeing to, the courts interpret the agreement as being governed by confirmatory deposits.

The three main types of deposit agreement in Spain

To understand the repercussions of each option, it is necessary to break down in detail the legal operation of the three types of deposit agreement used in the Spanish real estate market:

1. Confirmatory deposits (arras confirmatorias)

The primary purpose of confirmatory deposits is to confirm the existence of the sales contract and demonstrate both parties' firm commitment to complete the transaction. The sum handed over by the buyer upon signing is considered an advance payment towards the total property price and is deducted from the remaining balance payable on the day the public deed is executed.

It is vital to stress that this type of deposit does not entitle either party to terminate the contract unilaterally. Neither party can release themselves from the obligation to buy or sell simply by forfeiting or returning the sum paid in advance.

If one party unreasonably refuses to complete the purchase, the aggrieved party may invoke Article 1124 of the Civil Code and legally demand one of the following options:

• Enforced performance of the obligation: legally compelling the defaulting party to attend the notary public to complete the property transfer.
• Formal termination of the contract: with the right to claim compensation for damages suffered, the amount of which must be substantiated in detail before the judge.

2. Penitential or withdrawal deposits (arras penitenciales)

Penitential deposits, also known as withdrawal deposits, are the only ones directly codified in Article 1454 of the Civil Code. This option is notable for granting both contracting parties the legal right to withdraw unilaterally from the transaction without needing to provide any justification or initiate breach-of-contract proceedings.

The financial cost associated with such a withdrawal is defined from the outset in the agreement itself as follows:

• If the buyer chooses not to proceed with the property acquisition, they forfeit the entire deposit paid.
• If the seller decides not to transfer the property to the buyer, they must refund double the deposit amount received.

For a deposit to be deemed fully penitential, case law requires an explicit and unambiguous statement in the contract text. It is essential to mention the right of withdrawal literally and reference Article 1454 of the Civil Code. Failing this, the document will default to being classified as a confirmatory deposit.

3. Penal deposits (arras penales)

Penal deposits combine a guarantee of contractual performance with an advance determination of the penalty in the event of non-compliance with the commitments made. They are governed by the general provisions on obligations with a penalty clause set out in Article 1152 et seq. of the Civil Code.

Unlike penitential deposits, penal deposits do not grant the right to withdraw from the contract. Handing over the money or forfeiting it in the event of a breach does not release the defaulting party from their obligations.

In practice, when a breach occurs under a penal deposit agreement, the following consequences apply:

• The non-defaulting party can demand the forfeiture of the sum paid or its return in double, acting as a pre-agreed assessment of damages.
• Despite applying that penalty, the aggrieved party retains the right to demand enforced performance of the contract in court so that the transaction is formally completed.

Comparative analysis of deposit agreement types

To understand the differences between these three legal concepts more clearly, it is worth reviewing their three main differentiating criteria:

• Right of withdrawal: Exclusive to penitential deposits. Neither confirmatory nor penal deposits allow a signatory to pull out freely without facing legal action forcing them to buy or sell.
• Enforceability in court: Under confirmatory and penal deposits, signing the deed can be legally demanded through court proceedings. Under penitential deposits, once the pre-agreed penalty is enforced, the contractual obligation is fully extinguished.
• Assessment of damages: With confirmatory deposits, compensation must be calculated and proven in legal proceedings. With penal and penitential deposits, the financial loss or penalty is quantified from the exact moment the deposit agreement is signed.

Key aspects and common mistakes when drafting a deposit agreement

Drafting a deposit document requires technical precision and a detailed examination of the property's status. Imprecise terminology often leads to complex disputes where the parties' expectations do not match the legal reality of the contract.

Common mistakes in real estate practice include:

1. Ambiguous terminology: Stating that a "holding deposit" or "token payment" is delivered without specifying whether Article 1454 of the Civil Code applies results in Supreme Court doctrine classifying the agreement as a confirmatory deposit.
2. Omitting clear deadlines: Failing to set a precise deadline or timeframe for executing the public deed before a notary public creates legal uncertainty regarding when a default occurs.
3. Neglecting mortgage financing: If the purchase depends on a bank loan, failing to include a subject-to-mortgage clause can lead to the buyer forfeiting their deposit if the loan is rejected.
4. Social housing (VPO): For properties subject to special housing regimes, such as official protection housing (VPO) in the Comunidad de Madrid, it is essential to verify the maximum legal sales price and arrange the appropriate descalificación or administrative sale authorization in advance to prevent contract invalidity or penalties.

Final recommendation before signing a deposit agreement
