The bank has frozen your account: why it happens and how to unfreeze it
Your card stops working, a transfer hangs, the app shows "operacion no permitida" and the branch manager shrugs. A frozen account is the most common banking trouble a foreigner faces in Spain, and the cause is almost never you personally: it is the anti-money-laundering law. Here is why banks freeze accounts, which documents to prepare and how to act step by step to get your money back.
- The main reason for freezes is Ley 10/2010: the bank must know its client and the source of their money, and otherwise has to restrict transactions.
- Typical triggers: documents that were never provided, large incoming payments with no explanation, regular cash deposits, transfers from countries under enhanced scrutiny.
- The routine: ask in writing for the list of required documents, submit the complete package with translations, record the deadlines.
- If the bank does not respond, file a claim with its customer service department (SAC or defensor del cliente), then a complaint to Banco de España; the benchmark for a reply is 15 working days for payment services and up to 1 month for other matters.
- A freeze is not a confiscation: once the review is finished the bank must lift the restrictions or return the balance if it closes the account.
Why banks freeze accounts: Ley 10/2010
Spanish banks operate under the strict supervision of Ley 10/2010 on the prevention of money laundering and terrorist financing. It obliges the bank to apply "due diligence" (diligencia debida): to identify the client, understand the source of their income and monitor unusual transactions. If the bank cannot confirm this with documents, the law explicitly requires it not to process transactions, and that is where freezes come from.
Common triggers:
- the client did not reply to a request to update documents (KYC reviews happen regularly, and more often for non-residents);
- a large incoming payment that does not match the usual profile: a property sale, help from relatives, a crypto payout;
- regular cash deposits with no explainable source;
- transfers from countries subject to enhanced scrutiny or sanctions restrictions;
- an expired passport or TIE in the bank's file;
- suspected fraud, in which case the freeze protects you.
A separate story is a court, tax office (Hacienda) or social security seizure of the account over debts: that is not a banking freeze, and it is lifted by paying the debt or appealing to the body that ordered it.
Which documents the bank usually asks for
The set depends on the question the compliance department has raised. The most frequent requests are:
- a valid identity document: passport, TIE, and for non-residents proof of status;
- proof of income: employment contract and nominas (payslips), the Renta tax return, quarterly autónomo filings, a pension certificate;
- an explanation of a specific transaction: a sale and purchase contract, a deed of gift, inheritance papers, invoices, a statement from the sender's account;
- tax residency: the taxpayer number of another country, a residency certificate;
- for businesses, incorporation documents, beneficial owners (titularidad real) and turnover.
The bank may ask for documents that are not in Spanish to be translated, and official papers will need a sworn translation. The fuller and tidier the package, the faster the review.
Unfreezing step by step
- Find out the type of freeze. Ask at the branch or in the chat: is it a full freeze or a restriction on certain transactions, and is it the bank's own initiative or an order from an authority. The route depends on this.
- Ask for the list of documents in writing. Not "bring something about your income" but a specific list, in the app chat or by email, so that a record remains.
- Collect and submit the complete package at once. Submitting in instalments restarts the review. Attach a short covering letter: who you are, where the money comes from, what proves it.
- Record the submission and the deadline. Ask for confirmation of receipt and a benchmark review period; follow up politely every few days.
- No reaction means it is time for a formal claim to the bank's customer service department (see the next section).
- In parallel, secure your payments: move utility direct debits and your salary to a backup account so that the freeze does not create debts and late payments.
If the bank stays silent: SAC, defensor and Banco de España
By law every bank has a customer complaints department (Servicio de Atencion al Cliente), and many also have an independent defensor del cliente. The order is as follows:
- A claim to the bank's SAC. It is filed in writing (a form on the bank's website, at the branch or by email). Benchmark for a reply: 15 working days for payment service matters and up to 1 month for everything else.
- A complaint to Banco de España. If no reply arrives or it does not satisfy you, file a reclamacion with the Bank of Spain: online at bde.es (electronic identification required) or by letter. The procedure is free; the regulator asks the bank for an explanation and issues an opinion, and banks comply in most cases so as not to spoil their supervision record.
- Court. A last resort for cases of direct loss: Spanish courts regularly side with clients when funds have been withheld without grounds.
Important: a complaint does not stop you continuing the dialogue with the bank. Often the very fact of a formal claim speeds up a review that had stalled.
How to avoid a freeze: prevention
| Situation | What to do in advance |
|---|---|
| A large transfer is expected (a property sale, family support) | Warn the bank and show the contract or proof before the money arrives |
| Regular income from abroad | Document it: contract, invoices, tax returns |
| The bank asks you to update your details | Reply straight away, without putting it off: such requests have a deadline |
| A change of status (residence permit, job, address) | Update your profile at the bank, since outdated details raise your risk score |
| Cash | Keep cash deposits to a minimum; back up large sums with documents on their source |
Above all, do not ignore letters. Most freezes started with an ordinary request for documents that went unanswered. How to build the relationship with your bank from the start is covered in our article on the non-resident account.

Frequently asked questions
No. A freeze is a temporary measure until the review is complete. Once it has the documents, the bank must either lift the restrictions or terminate the contract and return the remaining balance (except in cases of a court seizure or a regulator's order). If the process stalls, a written claim to the SAC and a complaint to Banco de España usually speed things up.
A transfer from outside the EU is not forbidden in itself, but payments from countries under enhanced scrutiny and amounts above the client's usual profile take longer to check and more often require documents: a contract, tax returns, proof of source. Prepare the paperwork before the transfer rather than after and the money will not get stuck.
Benchmark: from 1 to 2 days for a simple document update up to several weeks if the origin of large sums is being checked. Speed depends on how complete the package is: a full set with translations and clear explanations goes through faster than documents submitted in instalments.
SEPBLAC is Spain's anti-money-laundering and counter-terrorist-financing authority. Banks must report suspicious transactions to it and are entitled not to explain the details of such checks to the client. That is why a bank sometimes formally says nothing: it is following Ley 10/2010, not being difficult.
Yes, there is no ban, and a backup account at another bank is sensible insurance for payments and a mortgage. But bear in mind that the new bank will run the same KYC check, and a large incoming sum on a brand-new history will raise the same questions. Transparent income documents solve the problem at both banks.
