This article explains clearly how to identify abusive clauses, what evidence to gather, how to communicate the claim to the landlord and which official resources and deadlines exist in Spain. It also guides on when to go to the Court of First Instance and how to seek mediation or free legal advice. Read calmly and keep all documentation; acting quickly and in writing improves your options to obtain a correction or reimbursement of amounts wrongfully charged.

What does it mean that the rent exceeds the index?

The rent exceeding the index can refer to different parameters: official update indices, caps set by regulation in tense rental areas or agreed clauses that prove abusive against the Urban Lease Act. If you detect a significant difference, review the contract and locate the update clause along with the start date of the obligation. For basic legal aspects consult the consolidated text of the LAU.[1]

In many regions, tenants are entitled to basic habitability standards.
