How a lawyer's client account really protects money when completing a purchase
In 30 seconds
A Spanish lawyer must keep your money in an account separate from the firm's own money, and cannot touch it without your written authorisation. But none of this stops the thing that really costs buyers money at this stage: a fraudulent email, arriving at exactly the right moment, giving you a different account number.
What exactly does the law require a lawyer to do with my money?
Three specific things, all from the Estatuto General de la Abogacía Española, and all enforced by the lawyer's own bar association, not just left to trust. The account holding your money must be kept clearly separate from the firm's operating account. It must be clearly named as a cuenta de clientes, and not blended into general funds. And the lawyer cannot use it without your written authorisation, which means a completion or a payment out must be something you actively approved, not something that simply happened as the file moved forward.Mishandling client money is not treated as a minor administrative mistake. It is classified as a serious or very serious professional violation, with penalties up to suspension or, in the worst cases, expulsion from the bar. This classification is what gives the rule real force, beyond just a written promise.
| What is required | What it means in practice | Source |
|---|---|---|
| Segregation | Your money sits in an account separate from the firm's own operating funds, never mixed with the practice's income or expenses. | RD 135/2021, art. 124.k |
| No unauthorised withdrawal | The lawyer needs your express written authorisation before drawing on the account for any purpose, including paying the seller. | RD 135/2021, art. 124.k |
| Disciplinary consequence for breach | Classified as a serious or very serious professional violation, carrying suspension or expulsion from the bar in the worst cases. | RD 135/2021 (general disciplinary regime) |
What happens to my money if my lawyer's firm itself goes bankrupt?This is exactly what segregation is designed to prevent from becoming your problem. Because client funds must sit apart from the firm's own operating account, they are not supposed to form part of the firm's general assets if the practice fails financially. This is a strong structural protection, but not a guarantee against every possible failure, which is exactly why choosing a firm with a genuine, checkable track record still matters.
Is a Spanish lawyer required to carry insurance on my money?
Yes, but the obligation sits in a different document than most buyers assume. It is worth being precise about which one, because this precision changes what you should ask to see.
What buyers assumeWhere the obligation really sits
- The bar admission rules themselves require every lawyer to buy insurance
- The Estatuto General de la Abogacía Española, the statute governing bar admission, does not list professional indemnity insurance among its own requirements. The obligation instead comes from the Código Deontológico, the profession's ethical code. Article 20 requires cover "in an amount adequate to the risks involved", rather than one fixed legal figure.
- Every lawyer buys their own individual policy
- In practice, most Spanish lawyers are covered through their own colegio's collective policy, rather than one bought individually. Either way satisfies the ethical obligation. What should never exist is no cover at all.
- There is one standard minimum coverage figure across Spain
- No source we checked states a single nationwide minimum figure. Cover is meant to match the risk of the work being done, which for a real-estate completion handling a large sum is a very different number than for a small consultation. Ask the specific firm what their cover really is, for a transaction the size of yours.
In practice, this means the useful question is never "are you insured", which almost every practising lawyer can answer yes to. The useful question is "what is your cover, individual or collective, and does it match a transaction of this size". Put this question in writing before any significant sum of money moves.
How do I check a lawyer's insurance rather than just take their word for it?Ask for the policy reference and the insurer's name in writing, and ask whether it is an individual policy or the colegio's collective one. A lawyer who is genuinely covered has no reason to be vague about either detail. An independent, reputable firm does not treat a request this specific and reasonable as an imposition.
What can I personally verify before any significant payment leaves?
Four things, none of which requires legal training, and all of which take a single email or phone call.
- The lawyer’s independence from the sellerConfirm that you chose the lawyer, or approved one recommended to you. It should not be a firm simply appointed by the selling agent, with no separate agreement with you.
- The account name on the payment instructionA genuine client account is titled as the firm’s cuenta de clientes, not a personal account or a generic business account.
- Bar membership, in writingWhich colegio de abogados the lawyer belongs to, and their membership number. A basic, checkable fact any practising lawyer states without hesitation.
- The written authorisation step itselfAsk the lawyer to confirm, in writing, that no payment leaves the client account without your express sign-off.
Is asking these questions considered rude or a sign of distrust?No. An independent lawyer used to working with foreign buyers expects exactly this kind of question. It is the same type of question as asking a bank for its regulatory registration number: routine due diligence, not an accusation.
What is the actual way people lose money at this stage, and how do you stop it?
Not through the client-account rule failing. It happens through a fraudulent email arriving at exactly the moment a large payment is expected, with bank details that look right and a tone that matches everything that came before it. This is a documented pattern across Spanish property transactions, not a rare exception: a law firm or notary's email account is compromised, and a message appears to come from someone genuinely involved in your file, asking you to send money to a "new" or "corrected" account.
[Compromised email]A payment-diversion attempt
- De / Responder a
- [email protected] / [email protected]
- Asunto
- URGENTE: cambio de cuenta bancaria
- Cuerpo
- “Nuestro banco ha cambiado…”
- IBAN
- ES00 0000 0000 0000 0000 0000
- De / Responder a. The reply-to address is subtly different from the sender. Easy to miss on a phone.
- Asunto. Urgency is the tell, not the content.
- Cuerpo. A legitimate firm does not change client-account details mid-transaction by email alone.
- IBAN. A new number, never confirmed by phone.
- Stop and verifyA changed account number arrives by email alone, mid-transactionA legitimate lawyer does not change client-account details this wayWhat to do insteadTreat it as suspicious by default, however convincing it looks
- Slow downThe message insists on urgency: a deadline today, a bank cut-offFraud is built to arrive with time pressureWhat to do insteadA genuine completion timeline rarely needs an unverified payment within the hour
- Stop and verifyNo prior phone verification of the account detailsA hacked inbox cannot fake a phone call you initiated yourselfWhat to do insteadCall the firm on a number you already had, never one from the email
- Good practiceA first large international payment with no test transferNothing has confirmed the receiving account is genuineWhat to do insteadWhere the timeline allows, send a small confirmed transfer first
The Spanish notary witnesses the signing and turns the sale into a public deed, and does not check whether the property is a good idea. The notary appointment itself is still one of the strongest structural defences against this specific fraud on a resale property: the balance is usually paid as a cheque bancario, handed over in person at the moment of signature, rather than wired without supervision days in advance. This mechanism, and why it exists, is covered in full on the money-protection page.Checking account details by phone before any balance moves is a standard step in Arevont's own legal-coordination process, specifically to close the gap this fraud pattern uses.
If I am scammed this way, is there any way to get the money back?Sometimes, if it is caught within hours. Contacting your own bank immediately to try a recall, and reporting it to the police, gives the best realistic chance. Once the money has moved on from the fraudulent account, which criminals do quickly and often across borders, getting it back becomes far less likely. Preventing this, by checking account details independently before sending anything, is far more reliable than trying to recover the money afterwards.
What to confirm before a significant payment leaves your account
Four checks, specific to the client-account mechanism, rather than to the purchase in general.| Ask for | What it tells you | What a bad answer looks like |
|---|---|---|
| Verbal confirmation of the account details, on a number you looked up yourself | This is the single most effective defence against a compromised-email fraud, because it does not depend on trusting the channel the instruction arrived through. | Being asked to simply reply to the same email confirming you will proceed, with no independent verification offered or suggested. |
| The account's name and its "cuenta de clientes" designation, in writing | Confirms the money is going to a genuinely segregated client account rather than a personal or generic operating account. | An account name that does not match the firm, or a reluctance to state what the account is called. |
| The lawyer's colegio and membership number | Ties the person holding your money to the disciplinary system that makes the segregation rule enforceable. | Vagueness about which bar association the lawyer belongs to. |
| Written confirmation that no payment leaves without your sign-off | This is the practical form article 124.k's protection of client funds takes in a real transaction. | An assumption that payments proceed automatically once documents are signed, with no separate approval step described. |
A verified payment channel, versus trusting the email you received
Both feel identical in the moment. Only one of them is really safe against the fraud that causes most real losses at this stage.| Trust in email | Verified channel | |
|---|---|---|
| How the account details were confirmed | Whatever number and details appeared in the message itself. | A phone call to a number you already had, independent of the email. |
| Resistance to a compromised email account | None: this is exactly the channel the fraud uses. | High: a hacked inbox cannot fake a phone call you initiated yourself. |
| Time cost | None, until something goes wrong. | A few minutes, once, before a large payment. |
| What happens if the money is sent to the wrong account | Often unrecoverable within hours, once the receiving account has moved the funds on. | Very unlikely to arise, because the account was independently confirmed first. |
The rule is real. It is not the whole of your protection
This is general information about the Estatuto General de la Abogacía Española and the Código Deontológico, current as of 17 August 2026, and read from the original sources rather than assumed from how the system is usually described. It is not a statement about any specific lawyer's account, insurance or conduct. The exact insurance figure a specific firm carries, whether individual or collective, is something only that firm can confirm, and no nationwide minimum is stated here, because no source we checked states one.The segregation rule and the disciplinary system behind it are genuine structural protections. But they do not address the most common real-world way people lose money at this stage of a purchase: a fraudulent email, not a lawyer breaking the rule. Good wire-fraud habits matter as much as the legal rule above them, and treating the law as the whole answer is the mistake worth avoiding.Deliberately left to their own guides: the two-route map of where money sits on a new build versus a resale property, which the money-protection page covers in full, and the bank-guarantee mechanism, which has its own page. Arevont is not a party to any client account described here, and does not hold client money at any point. Our part is checking, as part of the same legal-coordination process named above, that the account and the lawyer behind it are what they should be, before a significant payment moves.
Most common questions about a lawyer's client account
- Is a Spanish client account the same thing as a joint-signature escrow account?
- No, and this difference really matters. A joint-signature escrow account requires both sides to authorise a release together. A Spanish lawyer's client account works differently, through segregation and professional supervision: the lawyer holds the funds under strict rules and disciplinary oversight, and the buyer's protection comes from those rules, not from a shared signature requirement.
- Can I ask to see actual proof the account is separate from the firm's own money, rather than just being told it is?
- You can ask, and a clear answer is reasonable to expect, such as the account's designation as a cuenta de clientes and confirmation of which bank holds it. A full audit of a law firm's internal accounts is not something a buyer can demand, which is exactly why the disciplinary system, and your own choice of an independent, reputable firm, carry real weight here.
- Does using a power of attorney change any of the client-account protection?
- No. The account, the segregation rule and the authorisation requirement attach to the transaction and to you as the client, not to whether you personally sign in front of the notary or through a power of attorney. What changes is who physically signs, not which account your money passes through or how it is protected there.
- What should I do the moment I receive an email saying the bank details for my payment have changed?
- Stop, and do not reply to that email or use any phone number it contains. Call the firm on a number you already have, from earlier, verified contact, and ask directly whether the change is genuine. In the large majority of documented cases, this pattern is fraud, and the five minutes this takes is the whole cost of checking.
