What we assess

Who may be liable?

The perpetrators themselves are often out of reach. The decisive question is therefore which other parties involved may bear legal responsibility.

  1. Your bank or payment service provider

    For payments you did not authorise, a refund claim may be available. We also examine whether the bank is justified in relying on gross negligence.

  2. Recipient bank and account holders

    The money often ends up in third-party accounts, such as those of so-called money mules. Claims for repayment and damages may exist against the holders of these accounts.

  3. Platform operators and those behind them

    Anyone who offers financial services without the required licence or deceives investors may be liable for damages. Enforcement depends on whether those responsible can be reached.

  4. Intermediaries and advisers

    If you were advised on an investment or it was brokered to you, we examine whether disclosure and advisory duties were breached.

  5. Crypto exchanges and payment processors

    Regulated service providers must identify their customers. This can help trace payment flows – whether claims arise from this is a question of the individual case.

  6. Claims against anonymous perpetrators abroad often cannot be enforced. That is why we examine from the outset which other parties involved may come into consideration – and tell you openly if we see no realistic prospect.

How we work

    We implement the agreed strategy: towards banks, payment service providers and other parties involved, and in court if necessary.

Typical situations

Does this sound familiar?

This is how those affected typically describe their situation. The examples are typical scenarios, not actual cases.

  • “The broker refuses to pay out.”

    The customer account shows a large profit. But every withdrawal fails – first because of a “tax”, then because of an “activation fee”.

    Broker fraud
  • “After a text message from my bank, the account was empty.”

    A link led to a deceptively genuine-looking page. Shortly afterwards, several transfers were executed – the bank speaks of gross negligence.

    Phishing
  • “The investment platform is demanding further fees.”

    A personal “adviser” is pressing for additional payments so that the balance can be released. He responds to questions with growing irritation.

    Investment fraud
  • “I sent cryptocurrency to a wallet.”

    The trading platform showed profits but was a dummy. The coins were transferred onwards and contact has broken off.

    Crypto fraud
  • “A supposed bank employee called me.”

    To stop a “suspicious transaction”, I was told to confirm approvals in the banking app. In fact, I authorised transfers.

    Online banking fraud
  • “My bank has blocked my account.”

    Without warning, I can no longer access my money. I am given no reason, while rent and bills continue to fall due.

Do not make any further payments, inform your bank or card issuer immediately and have the affected access blocked. Secure receipts, chat histories and screenshots and report the matter to the police. A legal assessment is then advisable.
