Your bank account is blocked.
Here's what you can do.
Spanish banks can block accounts without warning — and often without giving any explanation. Here's what matters: when a block is legal, what rights you have, and how to send a written complaint that actually forces the bank to respond.

The same pattern, regardless of the bank
BBVA, Santander, CaixaBank, ING — it barely matters which bank. When an account gets blocked, the script is almost always the same: no warning, no clear explanation, no access to your money.
No warning
The block appears suddenly. A rejected payment, a card that stops working, online access cut off — with no prior communication.
No clear explanation
At the branch they say "it's a security review" or "an internal process." Nobody signs anything, nobody gives dates, nobody gives concrete reasons.
Indefinite timelines
"It should take 15 to 30 days" becomes months. Your money is inaccessible and nobody gives real answers.

A bank can't just block your account "because it wants to." There are specific legal grounds — and clear obligations toward the customer.
When a block can be justified
- Mandatory KYC identity verification (Ley 10/2010 on AML)
- Documented, well-founded suspicion of irregular activity
- Order from a regulator or court
- Documented breach of the account contract terms
Even in these cases, the bank is required to notify you in writing and give you the chance to submit documentation.
When the block is not acceptable
- No written notification and no specific reason
- Because you are a foreigner or non-resident, with no other grounds
- Low balance, without prior warning in the contract
- No defined timeline and no way to appeal
EU Directive 2014/92/EU guarantees the right to a basic payment account. The bank cannot cut off your access without documented grounds.
What to gather before making a complaint
- Account opening contract or welcome letter from the bank
- Valid ID, NIE or passport you submitted to the bank
- Recent bank statement showing the block
- Screenshots of the access error or rejected payment
- Any emails, SMS or letters from the bank about the block
- Record of calls or branch visits, with dates
- Name of the employee you spoke to, if you have it
- Any document requests the bank sent you
- Proof of residence or legal economic activity in Spain
- Tax return or employment contract showing source of funds
- Invoices or contracts explaining account movements
- History of regular account use (recurring payments, etc.)
💡 The more documented your case — the harder it is for the bank to extend the block without a proper response.
Mistakes customers make over and over
Waiting for it to resolve itself
The bank has no incentive to unblock the account if you don't push. Time works against the customer, not the bank.
Only going to the branch
In-person conversations leave no official trail. Without a written complaint, the bank can ignore the issue indefinitely.
Not demanding written reasons
"It's an internal process" is not an answer. You have the right to receive a written explanation with a concrete reason for the block.
Assuming there's nothing they can do
Many people believe the bank holds all the power. It doesn't: Spanish law and EU regulation give you specific rights and real complaint channels.
Sending documents without proof of receipt
If you send the bank documents without a delivery confirmation, you can't later prove you complied with what they asked for.
Not knowing about the Customer Service department
Before going to the Bank of Spain, you must exhaust the bank's internal channels. The SAC is legally required to respond within 1 month (Law 44/2002, art. 29 bis).
5 steps: from block to formal complaint
Document the block
Save screenshots, error messages, SMS from the bank. Note the exact date when access stopped. This is your starting point.
Request a written explanation
Contact the bank and explicitly request the reason for the block in writing. Verbal responses from branch staff don't count as an official answer.
Gather your documentation
Prepare your ID, proof of address, source of funds and anything that shows the legitimacy of your activity. The stronger the file, the better.
Submit a written complaint to the SAC
File a formal written complaint with the bank's Customer Service department. The bank has up to 1 month to respond (Law 44/2002, art. 29 bis). A written complaint completely changes the dynamic.
No response? Escalate to the Bank of Spain
If the bank doesn't resolve it in time or the response isn't satisfactory, you can file with the Bank of Spain's Conduct Supervision Department. But you must exhaust the internal process first.
A written complaint is almost always the right move
Even if the bank seems cooperative, even if they promise it's being reviewed — a written complaint changes your position. It sets a legal deadline and creates a record you can use if you need to escalate.
Creates an official record
Verbal promises at the branch mean nothing. A written complaint sets a date and forces the bank to respond officially.
Triggers legal deadlines
After a formal complaint, the bank has up to 1 month to respond (Law 44/2002). Without it, they can extend the block indefinitely.
Opens the door to the Bank of Spain
Without a prior SAC complaint, you can't escalate to the Bank of Spain. It's the mandatory first step for any further action.
✅ You can handle it yourself if:
- the bank communicated in writing what it needs
- you have the requested documents available
- the block is recent and looks like a routine check
- the bank responds to your contacts, even if slowly
🤝 Getting help makes sense if:
- no written explanation has been provided
- the block has lasted weeks with no resolution
- documents were requested but receipt wasn't confirmed
- the SAC didn't respond or rejected your complaint without clear reason
Generate your bank account block complaint
No need to write it from scratch. Answer a few questions and you'll get the complaint text, a PDF and a document ready to submit to the bank.
Frequently asked questions
Can a bank block my account without warning?
In most cases, not without explanation. Spanish law (Ley 10/2010 and Bank of Spain circulars) requires banks to notify customers of any restrictions and give them the opportunity to provide documentation. A silent block without written notice is a practice you can challenge.
The bank is asking for documents I already submitted. What do I do?
You need proof of what you sent and when. Resubmit the documents in writing (email or burofax) and keep the delivery confirmation. If you've provided everything and the bank is still blocking without response, that's sufficient grounds for a formal complaint to the SAC.
Do I have the right to a basic bank account in Spain as a foreigner?
Yes. EU Directive 2014/92/EU, transposed into Spanish law by Royal Decree-Law 19/2017, guarantees any EU resident the right to a basic payment account. Banks cannot deny you access solely on the basis of your nationality or non-resident status.
How long can the bank keep the account blocked?
It depends on the reason. For KYC verification, the bank should unblock once you've provided the required documents. An indefinite block without documented grounds and written communication is contrary to banking regulations. After a formal SAC complaint, the bank has up to 1 month to respond (Law 44/2002, art. 29 bis).
What is the SAC and how do I submit a complaint?
The SAC (Servicio de Atención al Cliente) is each bank's internal customer complaint service. You can submit a complaint in writing at any branch, by email, or through the bank's website. You must go through this process before escalating to the Bank of Spain or the CNMC.
Does this replace a lawyer?
No. The generator creates the SAC complaint — the first formal step, and the one that most often produces results. If the bank doesn't respond or rejects the complaint, RightNOW assesses next steps, including escalation to the Bank of Spain.
