Since 2026, renting seasonally in Spain takes more than a good contract: it takes proving why the tenant is passing through. This guide explains, in plain language, what the law requires and how to keep every contract documented and archived.

What a seasonal contract is (and is not)

A seasonal rental is a home let for a short term —1 to 11 months— with a specific reason: to work, study or receive medical treatment away from home. It is not the tenant’s primary residence.

The key is not the duration but the reason (the real motive for the stay). A three-month contract for no reason is not seasonal. An eleven-month one for a work relocation is —if you can prove it—.

What changed with Law 11/2025 in Catalonia

Law 11/2025, in force since January 2026, tightens control of seasonal contracts in Catalonia. When the reason is not documented, the contract is presumed to be an ordinary five-year tenancy. And it penalises simulated seasonal contracts with fines of up to €900,000.

It is not only Catalonia: a national rule is on its way, pointing in the same direction.

The risk across Spain: requalification

Even outside Catalonia, the risk exists. If a judge concludes that a seasonal contract had no real reason, they can requalify it as a primary-residence tenancy under the LAU (the Urban Leases Act): a five-year minimum term, renewals and rent subject to caps. The flat is tied up for years.

How to document the reason, step by step

  1. Identify the real reason for the stay: work, studies or health.
  2. Request the document that proves it (see table).
  3. Reflect it in the contract with a clause stating the reason.
  4. Archive it with the contract, ready to show if ever asked.

Which document proves which reason

ReasonUsual document
WorkEmployment contract or company letter, relocation order.
StudiesEnrolment or admission letter from the institution.
HealthMedical certificate or appointment (this is sensitive data: handle it with care).

The deposit: when and where

Besides the LAU deposit (one month rent), some regions require filing the contract and its documentation in a regional registry. In Catalonia, for example, with Incasòl. Always keep the deposit receipt.

Checklist: a well-documented seasonal contract

  • Reason identified (work, studies or health).
  • Document that proves it, collected.
  • Reason clause in the contract.
  • Deposit and regional filing, where applicable.
  • Tenant identity and income, verified.
  • Everything archived and easy to find.

Frequently asked questions

Is it enough to state work reasons in the contract?

Not enough. You must be able to prove that reason with a document. A clause without backing does not protect the contract.

What if the tenant is foreign?

The same: identity, income and a documented reason. Many seasonal tenants are paid outside Spain; verify all the same.

Does this replace my lawyer?

No. Documenting and archiving is a routine task; complex cases still need a lawyer. Tempora prepares and archives the documentation with templates pending partner-law-firm review.

Prefer we do it for you?

Tempora prepares the contract, documents the reason and archives the file inside the closed paid Spain pilot.
