What Happens After the Complaint Is Submitted?
The Protector’s Office will acknowledge receipt of each complaint and assign it a consecutive number for file identification. If additional information is required, it will be requested from the complainant. All communications and other actions within the complaint procedure will be carried out in writing.
The Investor Protector will verify jurisdiction and, if applicable, will inform the complainant of the acceptance of the complaint and the start of the relevant proceedings to examine and resolve the submitted matter. Cases in which the Protector lacks jurisdiction can be consulted in section 3.3 of Circular 8/1991, available at the following link: Protector Inversor - Normativa
If the Office determines it does not have jurisdiction, the complainant will be informed of this and advised of the appropriate channels or bodies to which they may turn.
Once jurisdiction has been confirmed and the complaint admitted, the procedure begins and generally follows these stages:
I - Request for additional documents or information from the complainant, if the Investor Protector’s Office deems it necessary to clarify insufficiently explained issues.
II - Forwarding of the documentation submitted by the complainant to the affected entity or entities so they may provide their arguments.
III - Communication of the entity’s arguments to the complainant. The Office may forward these to the complainant so they may respond within a period of no less than 15 days.
The issuance of the Final Report concludes the procedure, unless an agreement is reached beforehand. The process is confidential and free of charge.
The Investor Ombudsman analyses complaints and disputes from investors relating to stock market operations. This includes reviewing the actions of market participants—such as intermediaries, banks, and issuers—to determine whether investors' rights have been violated.
Although there is no set deadline for issuing the final report, efforts are being made to resolve claims as quickly as possible. The response time will depend on the cooperation of the entities involved and the submission of arguments by the parties, the deadlines for which will be calculated in accordance with Article 5 of the Civil Code.
