Documents to Calculate Maximum Rent Price in Spain
If you are a tenant in Spain and want to check whether your landlord can raise the rent according to a reference index, you need to gather several key documents. This guide clearly explains which papers to request and keep: lease agreement, rent receipts, written communications, reports on tense areas and calculations of the applied index. With those documents you can verify the legality of an update, prepare a claim or seek guidance in the courts. We avoid jargon and give practical steps, including deadlines and where to submit evidence. Keep digital and physical copies and note dates; well-organized documentation helps resolve disputes with the landlord.
Documents you will need
- Original lease agreement and any annexes or extensions.
- Receipts and proof of rent payments (last months and deposit if applicable).
- Written communications between landlord and tenant about increases or changes.
- Reports or certificates proving whether the dwelling is in a tense area.
- Document with the calculation of the reference index applied by the landlord.
How the maximum price is calculated according to the index
The calculation depends on the index applied in the contract or in the rule invoked; review the contract to see the update clause and compare it with the amounts and the indicated period. If the update is based on regulation or on agreements for tense areas, you will need the document that shows the percentage or coefficient used [1]. Keep receipts and a spreadsheet with the numbers to compare what was charged with what is permitted.
What to do if you suspect an illegal update
- Check deadlines and notification dates so you do not lose rights.
- Ask the landlord in writing for the calculation justification and keep the response.
- Seek advice from consumer services, housing offices or legal advisors.
- If appropriate, file a claim in the Court of First Instance with jurisdiction [2].

- What are tense areas?
- They are areas where the law or administration apply special rules to limit rent increases due to market pressure; there are usually official lists.
