What is an unlawful rent increase?

An unlawful increase occurs when the landlord raises the rent without legal basis, without respecting contract limits or without following procedures set by the Urban Leases Act. Consult the consolidated text to see the rules on rent updates and renewals in force in Spain[1].

In practice, many increases are resolved with clear documentation.

First things to do

  • Gather evidence: contract, receipts, written communications and any notice about the increase.
  • Calculate the claimed amount: difference between what was paid and what would apply under the contract and law.
  • Send a written claim to the landlord indicating the amount, the deadline you set and the request for a refund.
  • Respect deadlines: send the claim by means that provide proof and keep copies of everything.
Keep every receipt and written conversation to create a clear timeline.

FAQ

What deadlines do I have to claim an unlawful increase?
It depends: keeping documentation, you can make an extrajudicial claim and then consider judicial actions according to applicable prescription periods and current regulations.
Do I have to keep paying while I claim?
Yes, in general you should continue paying the current rent while the dispute is resolved; claim the difference later and document payments.
Can I go directly to court?
