Unexpected bank fees, overdraft charges and abusive clauses

Key rules

• Fees: A bank can charge only for services you asked for or actually received, and only fees listed in its published tariff brochure.
• Overdraft interest: Interest on an unauthorised overdraft is capped at 2.5 times the legal interest rate, on the overdrawn amount only.
• Abusive clauses: An abusive clause is void, and the bank must return what it charged you under it.
• Time limit: Wrongly charged fees generally have a five-year limit, so claim as soon as you spot the charge.
• Complaints: A complaint to the bank or the Banco de España does not replace a court claim.

Which charges you can challenge

Some bank charges are regulated, overdraft interest is capped, and abusive clauses are void. If a charge breaks one of these rules, you can ask for the money back.

The amount of a fee is not set by law and differs between banks. The rule is about when a fee is allowed. A bank may only charge for a service you asked for or that it actually provided. Every fee must also appear in the bank's published tariff brochure (the list of its fees). If a fee is not in the brochure, or you never used the service, dispute it.

Fees that are regulated

• Claiming an overdrawn balance. The bank can charge a commission for chasing an overdrawn account only if your contract provides for it and the bank has made a real, specific claim. It can charge it once per overdrawn position. It cannot repeat it for the same debt, add it on top of interest for the same debt, or charge it automatically with no real claim. It also cannot charge it if you have no genuine arrears.
• Cash machines. The machine's operator must show you its fee before you withdraw. Your own bank's fee must be agreed in advance.
• Transfers in euros within the EU. A cross-border transfer in euros must cost the same as a domestic one.
• Basic payment accounts. Fees are capped. The account is free if you are at risk of financial exclusion, and the fee is capped for everyone else.

Overdraft interest

An unauthorised overdraft (one you did not agree with the bank) cannot carry interest above 2.5 times the legal interest rate. Interest can be charged only on the amount actually overdrawn, and it cannot be compounded. The government resets the legal rate every year, so the cap moves with it. Ask your bank which rate it applies and compare.

Other consumer credit is covered by a different test: interest far above the normal market rate can be declared void by a court.

Abusive clauses

A clause is abusive if it was not individually negotiated and, against good faith, creates a significant imbalance between you and the bank, to your detriment. Banks must also write standard clauses clearly, so you can understand what they cost you.

An abusive clause is void and treated as if it were never in the contract. The rest of the contract usually stays in force. A court declares the clause void and can order the bank to return what it charged you because of it. This protects individuals on standard terms. It does not cover clauses you negotiated individually, or business customers in general.

How to dispute a charge

1. Complain in writing to your bank's customer service. Say which charge, the date and the amount, and ask for a refund. Keep proof you sent it.
2. If the bank refuses or does not answer, take the complaint to the Banco de España.
3. If that does not solve it, go to court. A complaint to the bank or the Banco de España does not replace a court claim.

The timeline below shows the steps and the decision below helps you choose the right route.

Time limit

Act quickly. For wrongly charged fees, the usual limit is five years from when you could first have claimed. For a clause declared abusive, asking the court to cancel the clause has no time limit. The limit on getting the money back is different. It is generally treated as starting when you knew, or could have known, that the clause was abusive. That is often the date of a final court ruling, or when you became aware of it. The start date is argued case by case, so get legal advice before claiming older charges.

Choosing between options

Is the charge a wrongly applied fee or an abusive clause?

• Challenge it as a wrongly applied fee: The contract allows the fee, but the bank charged it for a service you did not request, charged it twice, or charged more than the rules allow.

• Challenge it as an abusive clause: The fee comes from a standard-form term you did not negotiate that is unclear or creates a significant imbalance against you as a consumer.

• Accept the charge: The service was requested, the fee is in the tariff brochure, and you agreed to the term individually.

If the term was not negotiated, is not clear and transparent, and clearly favours the bank, treat it as abusive: a court can declare it void and order the bank to return what it charged. Otherwise treat it as a fee error and complain.

Timeline and deadlines

• Complain to your bank's customer service about the charge: as soon as you spot it

• Take the complaint to the Banco de España if the bank refuses or does not answer: after the bank's reply or lack of one

• Go to court to recover the money if the complaint does not solve it: within 5 years of when you could first claim

• Claim back charges based on an abusive clause: the nullity action has no time limit, and the 5-year period for getting the money back starts when you knew or could have known the clause was abusive

What to watch out for

• Fees for services you never asked for: A bank may only charge for services you requested or that it actually provided, and the fee must appear in its published tariff brochure. Charges outside that can be wrongly taken. Compare each charge on your statement with the tariff brochure and ask the bank in writing to refund any that do not match.

• Overdraft interest above the limit: Interest on a tacit overdraft cannot be more than 2.5 times the legal interest rate, and only on the overdrawn amount, without compounding. Higher or compounded interest can be wrongly charged. Ask the bank how it calculated the interest and request a refund of any excess.

• Abusive clauses: A standard-form clause that creates a significant imbalance against you is void, but the bank will not remove it by itself. Complain in writing, and if the bank refuses, take the case to court, where the judge can review the clause.

• Waiting too long to claim: Claims for wrongly charged fees generally expire after 5 years, and a complaint to the Banco de España does not stop that.

Frequently asked questions

Can my bank charge a fee for claiming my overdrawn balance?

Yes, but only if your contract provides for it and the bank made a real, specific claim for the debt. It can be charged once per overdrawn position, never repeated for the same debt and never on top of interest. If you had no genuine arrears, the charge is improper.

How much interest can a bank charge on an unauthorised overdraft?

For a tacit overdraft (an overdraft you did not agree in advance) on a consumer account, interest cannot exceed 2.5 times the legal interest rate. It applies only to the amount actually overdrawn, with no compounding. The legal rate is reset each year in the budget law, so the cap moves with it.

Will a court cancel the whole contract if one clause is abusive?

No, the court declares only the abusive clause void and the contract continues if it can survive without it. The bank then has to return what it unduly charged under that clause. This protects individual consumers on standard-form terms, not clauses you negotiated individually.

Is a complaint to the Banco de España enough to stop the time limit running?

No, a complaint to your bank's customer service and then the Banco de España does not replace court action. Ordinary claims for wrongly charged fees generally have a five-year limit.
