Repairs & upkeep (who pays what) 3 min read · published September 11, 2025

If you are in Spain and the landlord notifies a rent increase you consider improper, this practical guide shows how to act safely. I explain clearly tenants' rights, how to document the increase, which deadlines to respect and how to draft an effective objection letter. I also detail alternatives: negotiate, file an out-of-court complaint or go to court if necessary. You do not need to be a lawyer: follow the steps, keep copies of everything and use the sample letter provided to make a formal record. Acting quickly and with documentation increases your chances of success and protects your housing in Spain.

What you can do if the landlord raises the rent without notice

Faced with a rent increase you consider unjustified, the essential actions are to gather evidence, review the contract and communicate your objection in writing. If the update clause does not permit the increase or notices required by law were not respected, you have grounds to object formally.

  • Review the contract and note the rent update clause.
  • Keep evidence: messages, photos of documents and payment receipts.
  • Send an objection letter by burofax or certified mail and request acknowledgment of receipt.
  • If there is no agreement, consider filing a claim in the court of first instance.
Keep copies of all communications and evidence from the first moment.

Sample objection letter (guidance)

Always include: your details, the landlord's details, contract reference, date of the increase notification, a clear statement of objection and a request for correction or negotiation. State that you reserve legal actions if appropriate and request acknowledgment of receipt.

  • Sender and landlord details, and contract reference.
  • Date and detail of the communicated increase.
  • Reasons for the objection and evidence that supports your case.
  • Specific request: annul the increase or negotiate terms.
Sending the letter by burofax or certified mail makes it easier to prove notification in later proceedings.

Deadlines and practical steps

Acting within the deadlines set by the contract or law is crucial. If the increase affects an agreed automatic update, check that the correct index was applied; if the increase is unilateral and not provided for, object as soon as possible and keep acknowledgments.

  • Act within the deadlines set by your contract or notify your objection as soon as you receive the communication.
  • Keep receipts and communications as evidence.
  • Consult consumer guidance services or legal advice if in doubt.
