Credit card fraud: fraudulent debits and chargebacks

We examine refund claims for fraudulent card transactions and explain what role a chargeback procedure can play.

Overview

What this is about

Typical situations and warning signs

  • Your statement will show sales from retailers you have never purchased from.
  • Several small debits of unknown origin follow each other in quick succession - often a test of whether the card is working.
  • You entered card details on a site that was later found to be fake.
  • You shared a release code or confirmed a request in the app, and then your card was deposited in a third-party digital wallet.
  • Your card has been stolen or lost and transactions have been made with it.
  • A merchant repeatedly charges you for a subscription that you have not subscribed to.
  • The card issuer refuses the refund because the transactions were released with strong authentication.

Immediate steps

What you can do now

These steps make sense in most cases – regardless of whether you instruct us.

  1. Have the card blocked

    Have the card blocked immediately – with the card issuer or via the German blocking hotline 116 116. Note the date and time; as a rule, you are not liable for transactions made after the block was reported.

  2. Dispute the transactions and demand a refund

    Dispute the transactions concerned without undue delay and in writing with the card issuer and demand a refund. Also ask expressly for a chargeback procedure to be initiated.

  3. Check your statements in full

    Go through the transactions of the last few months and mark all entries you cannot account for. Small amounts are relevant too.

  4. Secure evidence and change your login details

    Save suspicious emails, text messages and screenshots of fake pages. Change passwords for retailer accounts and payment services where the card was stored, and check on which devices the card is registered digitally.

  5. Report the matter to the police

    File a report with the police. Many card issuers require the case reference number to process the dispute.

  6. Unsure what to do first in your case?

Legal assessment

Possible areas of review

  • Authorisation of the card transactions

    We examine whether the transactions were made with your consent. For unauthorised transactions, a refund claim under Section 675u of the German Civil Code (BGB) may be available.

  • The defence of gross negligence

    Under Section 675v BGB, the card issuer may rely on a grossly negligent breach of duty, for example in the handling of the PIN or approval codes. Whether the allegation holds depends on the specific course of events and must be proven by the card issuer.

  • Strong customer authentication

    If online payments or the storing of the card in a digital wallet were permitted without strong customer authentication, the defence of gross negligence may be excluded under Section 675v(4) BGB. We examine which procedure was actually used.

  • Chargeback procedure

    We examine whether a chargeback under the rules of the card scheme may be available, which dispute reason fits and whether the applicable deadlines are still running. There is no entitlement to a successful chargeback; the extent to which the bank must initiate a procedure with prospects of success depends on the individual case.

  • Notification and deadlines

    Unauthorised transactions must be reported without undue delay after you become aware of them. Under Section 676b BGB, claims are generally excluded if notification is not given at the latest 13 months after the debit.

Who may be liable

Possible opposing parties

  • Card issuer

    Against the bank or institution that issued your card, a refund claim may be available for unauthorised transactions. The chargeback procedure is also initiated there.

  • Retailer or payee

    If a retailer debited your card without a contractual basis or failed to deliver, repayment claims against it may be available. In the case of dubious providers abroad, however, enforcement is often difficult.

  • The perpetrators

    Claims for damages against the perpetrators exist in principle, but can only be enforced if the investigations lead to an identifiable person.

Whether and against whom claims actually exist depends on the individual case and can only be assessed after reviewing the documents.

Preserve evidence

Documents you should keep

Do not delete anything – not even out of anger or shame. Your account of events is enough for the initial enquiry; documents can be submitted later.

  • Credit card statements with disputed transactions marked
  • Complaint to the card issuer and their response letter
  • Confirmation of card blocking with date and time
  • Phishing messages and screenshots of fake pages
  • Notifications about releases, new devices or wallet registrations
  • Order documents and correspondence with the dealer
  • Issuer's card conditions
  • Criminal complaint and file number

FAQ

Frequently asked questions about Credit card fraud

General guidance – it does not replace advice on your individual case.

That depends on the individual case. For unauthorised card transactions, the law generally provides for a refund, provided you cannot be accused of gross negligence. We cannot give a guarantee – we examine how the prospects are to be assessed in your situation.
