Property escrow in Spain: notarial deposits, lawyer client accounts and how buyer deposits are protected

Spain does not have a statutory escrow system in the Anglo-American sense. There is no licensed escrow agent, no escrow statute and no escrow insurance fund. What exists instead is a set of four deposit custody mechanisms that serve the same protective purpose, each rooted in a different part of Spanish law. Understanding which one applies to your deposit, and who actually holds your money between the arras contract and the notary’s office, is the single most important practical question for a buyer.

What is property escrow in Spain?

Property escrow in Spain is the custody of buyer deposit funds by a neutral third party between the reservation contract and the notarial deed of sale. Because Spanish law does not recognise a formal escrow institution, the function is distributed across four mechanisms: the notarial deposit, the lawyer client account, the estate agent custodial account and the off-plan bank guarantee. Each has a different legal basis, a different level of protection and a different cost.

The notarial deposit is the closest Spanish equivalent to a true escrow. Under the Reglamento Notarial (articles 198 and following) and the Civil Code deposit provisions (articles 1758 and following), a notary can accept funds into an instrumental account, document the deposit in a notarial act (acta notarial) and release the money only when the conditions specified in the act are met. The notary acts as an impartial qualified custodian, not as a bank, and the practice is discretionary: the notary may accept or decline the deposit. This mechanism has grown with the influx of foreign buyers who expect escrow-style protection, as documented by the Consejo Notarial in its professional practice guidance.

How are off-plan deposits protected?

Off-plan deposits in Spain receive the strongest statutory protection of any property deposit, governed by the Disposicion Adicional Primera of the Ley de Ordenacion de la Edificacion (LOE, Ley 38/1999, as amended by Ley 20/2015). This provision absorbed and replaced the earlier Ley 57/1968, which was derogated with effect from 1 January 2016. The rules are mandatory and irrenunciable: a developer cannot contract out of them.

The LOE imposes two cumulative obligations on any developer who collects advance payments before or during construction. First, the developer must guarantee repayment of all amounts received plus legal interest, through either a seguro de caucion (surety insurance policy) issued by an authorised insurer or an aval bancario solidario (solidary bank guarantee) from a credit entity. The guarantee covers the full amount paid by the buyer, including applicable taxes, plus the legal rate of interest from the date of payment to the projected delivery date. Second, the developer must deposit advance payments in a special bank account (cuenta especial) at a credit entity, segregated from the developer’s own funds, and may only draw on the account for construction-related expenses. The bank is responsible for verifying that the guarantee exists before opening the account.

If construction does not start or does not complete within the agreed deadline, the buyer can rescind the contract and demand repayment of all amounts paid plus legal interest. The buyer must first make a formal written request (requerimiento fehaciente) to the developer. If the developer does not repay within 30 days, the buyer can claim directly from the insurer or the guarantor bank, which must pay within 30 days of the claim. The insurer cannot raise the developer’s contractual defences against the buyer. The guarantee is cancelled only when the habitability certificate (or equivalent first-occupation licence) is issued and the property is delivered to the buyer.

The Supreme Court has reinforced this framework in a line of cases establishing that the bank where the developer holds the special account can be jointly liable if it failed to verify the existence of the guarantee, even if no individual guarantee certificate was issued to the buyer. This makes the bank’s duty to check a practical enforcement tool for buyers who were never given their individual certificate.

Who holds the arras deposit in a resale purchase?

The arras penitenciales deposit, typically 10 per cent of the purchase price, is governed by Article 1454 of the Civil Code and is the standard pre-contract payment in Spanish resale transactions. The law does not specify who must hold this deposit, which is why the protection level depends entirely on the arrangement the parties negotiate. There are four common options.

Deposit holder	Legal basis	Segregation	Return on default	Protection level
Notary (deposito notarial)	Reglamento Notarial arts 198+, CC arts 1758+	Instrumental account, documented in acta notarial	Automatic return per acta conditions	Strongest
Lawyer (client account)	Bar association professional rules	Professional duty to segregate	Returnable but requires cooperation	Strong
Estate agent (cuenta deposito)	Professional conduct, no specific statute	Variable, no mandatory segregation	Depends on agent cooperation	Moderate
Seller directly	Contract only	None	Contractual claim only	Weakest

The notarial deposit is the strongest option because the notary is a public official who documents the deposit in a notarial act specifying the conditions for release or return. If the sale completes, the notary disburses the funds to the seller at the signing of the escritura publica. If the sale collapses, the notary returns the funds to the buyer according to the terms of the acta, or, if the parties disagree, consigns the funds with the court. The notary’s involvement is discretionary and may carry a custody fee, but the protection is superior because the acta notarial has full probative force and the notary is personally accountable for the proper handling of the funds.

The lawyer client account is the most common arrangement in practice. Spanish abogados are regulated by their regional Colegio de Abogados, which imposes professional conduct duties including the obligation to hold client funds separately. However, there is no specific statute governing lawyer client accounts in the way the UK Solicitors Regulation Authority rules do. The protection is professional rather than statutory, and if the lawyer fails to segregate or return funds, the buyer’s recourse is through the bar association’s disciplinary process and a civil claim.

Estate agent custody is the weakest of the third-party options. Spain does not have a specific statutory framework requiring estate agents to hold deposits in segregated client accounts. The Ley 2/2009 and Ley 5/2019 regulate credit intermediation and mortgage intermediaries, not estate agent deposit handling. Some agents maintain separate custodial accounts voluntarily, and the API (Agente de la Propiedad Inmobiliaria) college imposes professional standards on its members, but many agents do not have client accounts at all. In practice, agents are motivated to safeguard funds because their commission depends on completion, but the legal protection is thin.

Paying the deposit directly to the seller is the weakest option and should be avoided. The buyer’s only recourse if the seller refuses to return the money is a contractual claim, which may require litigation. Under the arras penitenciales framework, if the seller pulls out they must return the deposit doubled, but enforcing this against a seller who has already spent the money can be difficult and time-consuming.

What is a notarial deposit and how does it work?

A notarial deposit (deposito notarial) is the custody of funds by a Spanish notary in connection with a legal transaction the notary will document. The legal basis is found in the Reglamento Notarial, which regulates notarial acts (actas notariales) at articles 198 and following, and in the Civil Code’s deposit provisions at articles 1758 and following. The notary receives the funds into an instrumental account (cuenta instrumental), documents the deposit in a notarial act and holds the money until the conditions specified in the act are satisfied.

The procedure typically works as follows. Before the signing, the buyer (or their bank, if financing) transfers the deposit amount to the notary’s instrumental account. The notary has previously provided the account details and established conditions of admission: the identity of the depositor, the source of funds, the destination of the funds and the conditions for release. The notary documents the deposit in an acta notarial, which records the amount, the parties, the purpose and the release conditions.

At the signing of the escritura publica, the notary follows the depositor’s instructions and issues cheques or transfers from the instrumental account to the seller, to intermediaries, to the tax authority or to the parties’ legal representatives. If the sale does not proceed for any reason, the notary makes the funds available to the parties. If both parties agree on the disposition, the notary follows their instructions. If they disagree, the notary consigns the funds with the competent court. If the deposit was unilateral (only the buyer sent funds), the notary returns them to the depositor following their instructions.

The key advantage is that the acta notarial is a public document with full probative force. Anything agreed by the parties before the notary in the acta binds the notary fully, and if there is a conflict between a private contract and the acta, the acta prevails. This is based on Article 1230 of the Civil Code, which gives notarial documents their elevated evidentiary status.

How does the off-plan bank guarantee work in practice?

The off-plan bank guarantee is the most legally robust deposit protection in Spanish property law. Under the LOE Disposicion Adicional Primera, a developer collecting advance payments must provide each buyer with an individual guarantee document at the moment of signing the purchase contract. The guarantee must be issued by an authorised insurer (seguro de caucion) or credit entity (aval bancario solidario) and must cover the full amount the buyer will pay in advance, including applicable taxes, plus the legal rate of interest.

Requirement	Legal basis	What it means for the buyer
Individual guarantee document	LOE DA 1ª, Tres	Buyer receives a named policy or guarantee certificate at contract signing
Special bank account	LOE DA 1ª, Uno.1.b	Developer deposits buyer funds in a segregated cuenta especial
Bank verifies guarantee	LOE DA 1ª, Uno.1.b	The bank is responsible for checking the guarantee before opening the account
Insurer cannot oppose developer defences	LOE DA 1ª, Dos.1.e	The insurer or guarantor must pay the buyer regardless of disputes with the developer
30-day payment deadline	LOE DA 1ª, Dos.1.h	Insurer or guarantor must pay within 30 days of the buyer’s claim
Irrenunciable rights	LOE DA 1ª (inherited from Ley 57/1968 Art 7)	The buyer cannot waive these protections, even by contract

The practical workflow is straightforward. When the buyer signs the off-plan purchase contract, the developer hands over the individual guarantee document, which names the buyer, identifies the property and states the guaranteed amount. Each stage payment the buyer makes is covered by the guarantee. If the developer fails to deliver by the agreed deadline, the buyer sends a formal written request (burofax or equivalent) to the developer demanding repayment. If the developer does not repay within 30 days, the buyer claims directly from the insurer or guarantor bank, which must pay within 30 days.

The Supreme Court has held in a series of judgments that the bank where the developer holds the special account is jointly liable with the developer if it opened the account without verifying the existence of the guarantee. This means that even if a buyer never received their individual certificate, they can still claim against the account-holding bank, because the bank failed in its statutory duty to check. This doctrine has been a critical protection for buyers in cases involving developer insolvency.

What is the difference between a notarial deposit and a lawyer client account?

The difference between a notarial deposit and a lawyer client account is the legal basis and the level of institutional protection. A notarial deposit is documented in a public deed (acta notarial) by a public official who is personally accountable for the funds, with full probative force under Article 1230 of the Civil Code. A lawyer client account is held under professional conduct rules enforced by the regional bar association, with no specific statutory framework for segregation and no public deed documenting the deposit.

In practice, both mechanisms provide reasonable protection for buyer funds, and the choice often depends on the transaction structure. If the buyer’s lawyer is handling the conveyancing, the lawyer will typically hold the deposit in their client account as part of the service. If the buyer wants the strongest available protection, or if the transaction involves a foreign bank sending funds directly, a notarial deposit may be preferable because the notary’s acta creates an immutable record of the conditions for release and return.

The cost also differs. A notarial deposit may carry a custody fee charged by the notary, which varies by notary and by the amount held. A lawyer client account is typically included in the conveyancing fee, though some lawyers charge separately for fund handling. Neither option is free, but the cost is modest compared to the deposit amount at risk.

What should a non-resident buyer do to protect their deposit?

A non-resident buyer should take three practical steps. First, never pay a deposit directly to the seller if a third-party option is available. The arras contract is legally binding regardless of who holds the money, but enforcing a return (or a doubled return) is far easier when the funds are already in a segregated account. Second, request a notarial deposit if the transaction involves a significant deposit or if the buyer’s bank is sending funds from abroad, because the acta notarial provides the strongest documentary protection and the notary is a neutral public official. Third, for any off-plan purchase, verify that the individual guarantee document is received at contract signing and that the bank account details match the special account designated in the contract.

For off-plan purchases specifically, the buyer should also check that the developer’s advertising and promotional materials name the guarantor entity and the special account bank, as required by the LOE. The absence of this information in the developer’s marketing is a warning sign that the statutory protections may not be in place.
