OMIC Complaint for Tenants in Spain

Claims & mediation (consumer offices) 3 min read · published September 11, 2025
If you are a tenant in Spain and have an issue with rent, repairs, the deposit or landlord business practices, you can file a complaint with the Municipal Consumer Information Office (OMIC). The OMIC offers free guidance and can mediate or process administrative complaints, but it does not replace a judicial procedure in eviction cases or complex contractual disputes. Before going, gather contracts, receipts, photos and communications with the landlord; note dates and deadlines. This article explains step by step how to prepare your complaint, what evidence to attach, important deadlines and alternatives such as mediation, Consumer Boards or going to court if the OMIC does not resolve your case.

What the OMIC does

The OMIC (Municipal Consumer Information Office) is a local service that advises consumers and users, receives complaints and can mediate between parties. For rental matters, basic legislation such as the Urban Leases Act regulates contracts and obligations, but the OMIC acts at an administrative and mediation level, not as a judge.[1]

The OMIC can mediate and advise, but it does not replace the court in complex disputes.

When to go to the OMIC

  • Claims for improper charges or rent increases.
  • Request repairs or address habitability problems.
  • Complaints about abusive clauses in the contract or lack of information.
  • Submit evidence: receipts, photos and communications with the landlord.
Documenting dates and conversations makes the process easier and increases the effectiveness of your complaint.

How to file a complaint with the OMIC

Before contacting the OMIC, prepare a file with basic information and evidence. Bringing everything organized speeds up processing and helps mediation.

  • Lease agreement and payment receipts.
  • Photos or recordings that show the problem.
  • A short written statement explaining the facts and the remedy you request.
  • Key dates: start of the problem, communications and deadlines.
Always keep copies of everything you submit and request a proof of filing.

Deadlines and possible outcomes

Resolution times vary by municipality and case complexity; the OMIC can forward the complaint to the Consumer Arbitration Board or propose mediation. If the issue requires a judicial decision (for example, eviction or unresolved contractual dispute), you must go to the Court of First Instance competent for your area.[2]

Responding to notifications and respecting deadlines prevents losing legal options.
