Legal representation is mandatory in the court proceedings. The application must be addressed to the Budapest-Capital Regional Court, and submitted electronically through the MNB’s form submission support service.

The submission of the application has no suspensive effect on the enforceability of the resolution/ruling, but the customer may request interim relief. As a general rule, the court rules in the proceedings without holding a hearing; however, the customer may request a hearing in the application. If no hearing is requested, a hearing may not be requested later on during the appeal procedure.

An application for a remedy may be lodged by any party who goes over a time limit or misses a legal deadline during the procedure for reasons beyond their control.
