Contrato de Arras Spain: The Complete Guide to Spain's Property Deposit Contract

The contrato de arras in Spain is the most important document in any property purchase between the initial handshake agreement and the final notarial deed of sale. It is the point at which a verbal understanding becomes a legally binding commitment — the moment the price is locked in, the property is reserved for the buyer, a completion deadline is set, and real financial consequences attach to any withdrawal by either party. For international buyers purchasing property in Mallorca, understanding the contrato de arras before signing it is not merely sensible housekeeping. The three different types of arras contract recognised under Spanish law carry dramatically different consequences if a purchase falls through, and choosing the wrong type — or signing one that fails to specify the type clearly — can result in the loss of tens of thousands of euros or a court dispute rather than the clean exit the buyer assumed was available. This guide covers everything: how the contrato de arras works, the three types and their legal consequences, how much the deposit should be, the key clauses that protect both buyer and seller, the most common pitfalls and what happens at each stage of the process.

What Is the Contrato de Arras?

The contrato de arras — literally the deposit contract — is a private written agreement between buyer and seller that formalises the terms of a property sale before the final public deed is signed at the notary. It is not legally mandatory under Spanish law; a property sale can technically proceed from verbal agreement to notarial completion without one. In practice, however, it is used in virtually all residential property transactions in Spain and serves a function that is essential to a well-ordered purchase process.

At its core, the contrato de arras does four things. First, it reserves the property exclusively for the buyer — the seller cannot accept other offers or complete a sale to a third party while the arras contract is in force. Second, it locks in the agreed purchase price — neither party can renegotiate the price after signing without the other's consent. Third, it establishes a deadline by which the final notarial deed must be signed — this completion date gives both parties a clear timeline for mortgage applications, legal due diligence, surveys and the practical logistics of closing. Fourth, it creates a financial structure that makes withdrawal costly for both parties — the deposit paid by the buyer at signing functions as a performance bond for both sides, with the consequences of withdrawal defined by the type of arras chosen.

The contrato de arras is a private document — it does not need to be signed before a notary or registered with any public authority to be valid, though it can be. It is drafted specifically for each transaction and can be prepared by the estate agency, the buyer's or seller's lawyer, or a Spanish gestoría. Because the document is not standardised, the drafting quality varies considerably, and using a qualified Spanish property lawyer to review or prepare the arras contract is always recommended.

The Three Types of Arras Contract — and Why the Difference Matters

Spanish law recognises three distinct types of arras, each governed by different articles of the Spanish Civil Code and each carrying fundamentally different consequences if the purchase does not complete. The type must be explicitly stated in the contract — if it is not, Spanish courts interpret the contract as arras confirmatorias by default, which is typically the least favourable outcome for a buyer who needs flexibility.

1. Arras Penitenciales — The Most Common Type

Arras penitenciales are governed by Article 1454 of the Spanish Civil Code and are by far the most common type used in residential property transactions in Mallorca and across Spain. They are the type that most international buyers encounter and the type that estate agencies typically use as standard.

The defining characteristic of arras penitenciales is that they give both parties an explicit right of withdrawal from the transaction — at a price. If the buyer withdraws from the purchase after signing, they forfeit the entire deposit. If the seller withdraws — for any reason, including deciding they no longer want to sell or accepting a higher offer from another buyer — they must return double the deposit to the buyer. The double return rule is not negotiable and is not subject to any mitigation: if a seller receives a 50,000 euro arras deposit and then withdraws, they must return 100,000 euros to the buyer.

This structure creates a powerful mutual deterrent. The buyer cannot simply change their mind without losing the deposit, which protects the seller from time-wasters who tie up their property with no serious intention of completing. The seller cannot renege on the deal to chase a higher offer without paying a significant penalty, which protects the buyer's position once the price has been agreed. For the Mallorca property market — where demand is strong and sellers occasionally receive higher offers between arras and completion — this protection is genuinely valuable.

The critical legal point is that with arras penitenciales, withdrawal and payment of the penalty is the end of the matter. The withdrawing party cannot be compelled to complete the sale, and the other party cannot sue for additional damages beyond the deposit forfeiture or double return. This is the clean-exit mechanism that most buyers need, and it is why this type is standard.

A worked example: a buyer agrees to purchase a Santa Ponsa villa for 1,200,000 euros and signs an arras penitenciales contract with a 120,000 euro deposit (10 percent). Before completion, the buyer's circumstances change and they decide not to proceed. They lose 120,000 euros and the seller retains it — the transaction ends there. If instead the seller withdraws, they return 240,000 euros to the buyer — their original 120,000 euros plus a further 120,000 euros as the penalty. The transaction ends there with no further legal claim available to either party.

2. Arras Confirmatorias — The Binding Commitment

Arras confirmatorias are the type that Spanish courts apply by default if the contract does not specify otherwise, and they are significantly more binding than arras penitenciales. The deposit paid under arras confirmatorias functions simply as a partial payment of the purchase price — a down payment confirming the sale — rather than as a penalty bond.

The critical difference from arras penitenciales is that there is no automatic right of withdrawal under arras confirmatorias. If either party pulls out of the transaction, the other does not simply receive the deposit or double the deposit and walk away. Instead, the non-withdrawing party has two options, governed by Articles 1101 and 1124 of the Spanish Civil Code: they can demand specific performance — that is, force the completion of the sale through the courts — or they can claim termination of the contract plus full compensation for all damages suffered as a result of the withdrawal. Either route requires legal action, and either can result in a financial liability that far exceeds the deposit amount.

For a buyer who signs arras confirmatorias and then discovers they cannot proceed — because a mortgage is refused, because a survey reveals a serious defect, or simply because their circumstances have changed — the position is considerably more dangerous than under arras penitenciales. They cannot simply lose the deposit and exit. The seller can take them to court and claim damages for the full loss caused by the failed sale, potentially including the cost of relisting the property, any reduction in achieved price, and consequential losses. The buyer's exposure is theoretically unlimited relative to the deposit amount.

Arras confirmatorias are more commonly used in commercial property transactions and between parties who are both absolutely certain the sale will complete and want the strongest possible mutual commitment to doing so. They are rarely appropriate for standard residential purchases by international buyers, particularly those who need a mortgage, are buying from abroad, or have any degree of conditionality in their position.

3. Arras Penales — The Hybrid

Arras penales occupy a middle position between the other two types and are regulated by Articles 1152 to 1154 of the Spanish Civil Code on penalty clauses. Like arras penitenciales, they establish a financial penalty for withdrawal — the buyer loses the deposit, the seller returns double. But unlike arras penitenciales, the payment of the penalty does not necessarily extinguish the other party's right to seek completion of the sale through the courts.

In practical terms, arras penales mean that a withdrawing party faces both the financial penalty and the possibility of being compelled to complete the transaction or pay full damages in addition to the penalty. The non-withdrawing party can choose to accept the penalty as full resolution, but they are not required to do so. This makes arras penales the most onerous type for the withdrawing party and is one reason they are used less frequently in standard residential transactions. They are more common where one party — typically a developer — wants to maximise their protection against the other's withdrawal while retaining maximum enforcement options.

Which Type Should You Use?

For the vast majority of residential property purchases in Mallorca by international buyers, arras penitenciales is the correct choice. It provides strong mutual protection, a clear financial penalty structure and a clean exit mechanism that does not require legal action. It is the standard in the market and the type most estate agencies, lawyers and notaries expect to see.

Arras confirmatorias should be avoided by buyers who have any conditionality in their position — mortgage dependency, ongoing due diligence, a property to sell, or any other factor that could prevent completion. If a contract does not explicitly state the type of arras and reference Article 1454 of the Civil Code for penitenciales, assume it defaults to confirmatorias and ask for it to be corrected before signing.

Arras penales are occasionally appropriate where a buyer wants the strongest possible deterrent against a seller withdrawing, but the double-exposure risk on the buyer's own withdrawal makes them a double-edged instrument that requires careful legal advice before use.

How Much Should the Deposit Be?

Spanish law does not fix a mandatory deposit amount for the contrato de arras. The amount is freely negotiated between the parties. In practice, the standard in the Spanish residential market — including Mallorca — is 10 percent of the agreed purchase price, and this is the figure that the vast majority of arras contracts use.

At 10 percent, the deposit is large enough to represent a serious deterrent to withdrawal by either party without being so large as to create excessive financial exposure for a buyer at the reservation stage, before all due diligence has been completed. On a 500,000 euro property, a 10 percent deposit of 50,000 euros is a meaningful commitment. On a 2 million euro property, 200,000 euros is a serious financial stake that concentrates both parties' attention.

Some transactions use a two-stage structure: a smaller initial reservation deposit (typically 3,000 to 10,000 euros) paid at the point of offer acceptance to hold the property while the arras contract is prepared, followed by the full 10 percent deposit on signing of the arras. The reservation deposit is generally credited against the arras deposit when the arras contract is signed. If the arras contract is not signed within the agreed period, the reservation deposit is returned to the buyer.

In high-demand situations — where a seller is choosing between multiple interested buyers — some sellers request deposits above 10 percent. 15 percent is not uncommon at the premium end of the Mallorca market. From a buyer's perspective, a higher deposit increases the risk exposure if the purchase does not proceed for reasons outside their control, and is worth resisting unless genuinely necessary to secure the property.

The Key Clauses Every Arras Contract Should Contain

A well-drafted contrato de arras protects both parties by being specific about every material term. The following clauses are essential and should be verified before any arras contract is signed.

Full identification of the parties. Both buyer and seller must be identified by full name, passport or DNI number, and NIE number. If the seller holds the property through a company, the company's CIF number and the signatory's authority to act on behalf of the company must be verified. If the buyer is purchasing in joint names, all buyers must be named.

Complete property description. The property must be described by its full address, its registry number (número de finca registral), its cadastral reference (referencia catastral), and the surface area as registered. Any parking spaces, storage rooms or other ancillary spaces included in the sale must be explicitly listed with their own registry numbers.

The agreed purchase price. The full agreed price must be stated in euros. If the price includes furniture or other movable assets at an agreed value, these should be itemised separately.

The deposit amount and payment method. The arras deposit amount must be stated, together with the payment method. Bank transfer is standard and preferable to cash, as it creates a clear paper trail.

The type of arras — explicitly stated. This is the most important clause. The contract must state clearly which type of arras applies and, for arras penitenciales, should reference Article 1454 of the Spanish Civil Code explicitly. Without this, the contract defaults to confirmatorias in any court dispute.

The completion deadline. The contract must set a specific date — not a vague period — by which the escritura publica (notarial deed of sale) must be signed. The deadline must be realistic: for purchases requiring a non-resident mortgage, a minimum of 60 to 90 days is advisable given the six to eight week processing timeline of Spanish banks in 2026. For cash purchases, 30 to 45 days is typically sufficient.

The mortgage condition clause. For buyers who need a mortgage, this clause is essential and is frequently omitted from poorly drafted arras contracts. A mortgage condition clause states that if the buyer's mortgage application is refused — by a named lender or by any lender — the buyer may withdraw from the purchase and recover the full deposit without penalty. Without this clause, a buyer whose mortgage is refused faces losing their deposit under arras penitenciales or potentially facing legal action under arras confirmatorias. The clause should specify a deadline for obtaining mortgage approval and the mechanism for notifying the seller of a refusal.

The allocation of purchase costs. The contract should specify who pays each category of purchase cost: ITP transfer tax (buyer), notary fees (typically seller for the deed of sale, buyer for any mortgage deed), land registry fees (buyer), plusvalía municipal tax (seller under standard Spanish practice, though negotiable), and gestoria fees (agreed between parties). Leaving this unspecified risks disputes at completion.

The property's legal status at signing. The seller should warrant in the arras contract that the property is free of encumbrances, charges and outstanding debts — or disclose any that exist. Specifically: no outstanding mortgages (or agreement that any mortgage will be cancelled on or before completion), no community of owners fees in arrears, no outstanding IBI property tax, no pending legal proceedings affecting the property, and no known planning or structural issues. The buyer's lawyer should verify this against the nota simple from the Land Registry before signing.

The notification method. For any formal notifications between the parties — particularly if one party seeks to invoke the withdrawal penalty — the contract should specify the method: typically burofax (a certified postal service with legal evidential value in Spain) or notarised notification. Vague notification provisions create opportunities for disputes about whether notification was validly made.

The Most Common Pitfalls

The following errors occur regularly in arras contracts and each has cost buyers and sellers significant sums of money.

Failing to specify the type of arras. As noted, default to confirmatorias in any ambiguity. This single omission transforms a flexible exit structure into a legally binding commitment to complete.

Setting an unrealistic completion deadline. A 30-day deadline when the buyer needs a non-resident mortgage is inadequate — Spanish banks currently take six to eight weeks minimum to process non-resident applications. If the deadline passes without the mortgage being in place and the notary signing not having occurred, the seller can claim the deposit regardless of the reason for the delay.

Omitting the mortgage condition clause. Buyers who need a mortgage and do not include this clause are taking a significant and unnecessary risk. If the bank says no, they lose the deposit.

Not verifying the property's legal status before signing. The nota simple from the Land Registry should be obtained and reviewed by a lawyer before any deposit changes hands. Undisclosed mortgages, community fee arrears, charges and legal proceedings affecting the property all appear on the nota simple and can be deal-breakers that are far cheaper to discover before signing than after.

Paying the deposit in cash. Cash payments create no paper trail and complicate the recovery of the double deposit if the seller withdraws. Bank transfer is the correct method.

Not having the contract reviewed by a lawyer. The cost of a Spanish property lawyer reviewing an arras contract is a fraction of the deposit at stake. The market for legal services in the Mallorca international community is well-developed and English, German and other language legal advice is readily available across the southwest.

From Arras to Completion — The Process

Once the contrato de arras is signed and the deposit paid, the purchase process enters its active phase. The buyer's lawyer completes the due diligence — verifying planning permissions, checking for any urban charges (cargas urbanisticas), confirming the community of owners is in good standing, and reviewing the building's energy efficiency certificate. The mortgage application (if applicable) is submitted and progressed. The notary appointment is arranged for the completion date agreed in the arras.

At the notarial completion — the signing of the escritura publica de compraventa — the balance of the purchase price (total price minus the arras deposit already paid) is transferred. The buyer's mortgage funds are released simultaneously if applicable. The notary reads the deed to both parties, both parties sign, and ownership transfers at the moment of signing. The arras deposit is credited against the purchase price — it is not paid again at completion but deducted from the remaining balance due.

After completion, the buyer's gestoría or lawyer handles the registration of the new ownership at the Land Registry and the payment of ITP transfer tax within the required 30-day period. The process from arras signing to registered ownership typically takes two to four months for a standard residential purchase in Mallorca.
