Procedure details

The Federal Financial Supervisory Authority (Bundesanstalt für Finanzdienstleistungsaufsicht – BaFin) supervises banks and financial service providers, insurance companies and securities trading. It also deals with collective consumer protection.

If you have any queries about supervised companies, consumer protection in the financial sector, or if you are considering filing a complaint against a financial service provider, you can ring BaFin’s consumer hotline on the freephone number 0800 2 100 500.

You can lodge a complaint with BaFin against a company in the financial services sectorif, for example, you think that you have been badly advised or have problems with the execution of contracts. You can also contact BaFin to give tip offs about price manipulation or insider trading.

However, BaFin can only deal with complaints relating to the companies that are subject to its supervision and cannot make binding rulings on individual disputes. Only a court can provide binding rulings on disputed points of law and impose sanctions such as financial penalties on companies. If you want a judgeruling on your case, you will have to sue the company in question.
