We file a complaint against your broker, bank or fund manager before the CNMV's Servicio de Reclamaciones del Inversor (investor complaints service) for deficient risk information, improper fees, unauthorised transactions, mis-sold complex products (preferentes or preference shares, subordinadas or subordinated debt, investment funds), execution errors and any MiFID II malpractice. If you have not yet complained to the firm's SAC (customer service department) or Defensor del Inversor (investor ombudsman), we first draft that written submission at no extra cost.

  • Communications with the SAC (customer service department) or Defensor del Inversor (investor ombudsman): emails, reference number, reply. You do not need to upload it here.

Legal basis and things to bear in mind

  • The CNMV is free of charge: you pay no tasa (official fee) to the body. Our 149 € cover the technical drafting and the submission.
  • The CNMV resolution is NOT binding on the firm, but it is key evidence in a civil claim for nullity due to defective consent (art. 1266 CC, deadline of 4 years from becoming aware of the error).
  • For preferentes (preference shares) and subordinadas (subordinated debt), the case law of the Tribunal Supremo (Supreme Court) has been particularly favourable to retail investors: the absence of a properly conducted idoneidad (suitability) test presumes defective consent.
  • If your case involves more than 5.000 € or the product is complex, it is usually worthwhile to also start court proceedings in parallel. We will guide you.
