One sentence in the contract decides which law governs your tenancy: the reason you are only living here temporarily. It sounds like a formality and is the opposite of one. Without it, it is not a seasonal let.
Why the law asks for a reason
Spanish tenancy law knows two worlds. One is the home someone lives in permanently — heavily protected, with extension rights running for years. The other is letting for a purpose other than permanent living, set out in Article 3.2 of the LAU. Seasonal letting belongs there.
The difference is not the duration but the need. Someone moving here for eight months because a project runs eight months has a temporary need. Someone moving here to stay does not — even if the contract says eight months.
That is why the reason is written down. It shows that both sides assumed a limited stay from the start.
What counts as a reason
It need not be dramatic. Typically recognised:
- Fixed-term work — a temporary contract, a posting, a project, a season
- Study or training — a semester, a course, an internship
- Building or renovating — your own property is not liveable right now
- Medical treatment — for yourself or as a companion
- Wintering — a clearly limited stay with a return
- A transition — between two homes, after a move, while searching
What matters is that it holds up. This is not about collecting paperwork; it is about the reason being real and nameable.
How it enters the contract
A seasonal tenancy agreement usually records three things: the purpose in one sentence, a fixed start and end date, and a statement that the property does not serve as a permanent residence. These three belong together — an end date without a reason is just a deadline, not evidence of a temporary need.
A good contract does not invent the reason; it writes down what is true anyway.
What happens when the reason is missing
If the temporary purpose is absent or plainly pretextual, a dispute can see the contract reclassified as an ordinary residential tenancy. For the owner that means extension rights nobody planned for. For the tenant it means uncertainty about which rules actually apply — to the deposit, to notice, to handing the property back.
Both sides therefore share an interest in that sentence being accurate.
How we handle it
On MUVAWAY, the tenant states the genuine reason for the stay in their rental profile. The owner reviews the enquiry and makes the decision. Both parties clarify the temporary purpose before signing and record it in their agreement; the platform provides digital tools for the process.
Which evidence actually holds up
A reason merely asserted in the contract is a weak reason. What carries it is a document that exists independently of both parties:
- Work: a posting letter, a fixed-term employment contract, a services contract or a project order with an end date.
- Study: proof of enrolment, admission to a language course, an internship agreement.
- Renovation: a building application, a builder's quote or a permit for your own property.
- Buying a property: a preliminary contract (contrato de arras) with an expected completion date.
- Treatment: an appointment confirmation or a treatment plan from a clinic.
These documents do not go into the listing and are not published. They are internal evidence in case the classification of the contract is ever questioned.
What is not a workable reason
"I want to try Mallorca out" is honest, but it is not a temporary purpose in the legal sense. The same goes for "I am still looking for a place to buy" with no concrete transaction, and for "I am spending the summer here".
The difference is not about sympathy but about structure: a temporary purpose has a foreseeable end that does not depend solely on the tenant's mood. A project ends. A semester ends. A renovation ends. A feeling about life does not.
That does not mean nobody can rent in Spain without such a reason — it means a different contract type is the right one, with different rights and obligations on both sides.
The borderline case: wintering
Winterers are the most common doubtful case. Someone arriving from November to March because it is milder here has a clearly bounded stay — but no occupational or medical reason in the narrow sense.
In practice this is mostly handled as a seasonal rental, because every other feature fits: a fixed period, no centre of life in Spain, residence and registered address remaining in the home country. If you want to be safe here, document exactly that — the continuing main residence abroad.
What would tip the case: registering locally, becoming a Spanish tax resident, children in a local school. Then someone lives here, and the contract should reflect it. More on this in the wintering guide.
Why this protects the tenant too
The temporary purpose sounds like a hurdle for the tenant. In fact it protects both sides, because it makes expectations match.
For the owner it means the property comes back on the agreed date, with no right of extension. For the tenant it means the owner cannot end the tenancy mid-term because a better offer arrived — and the terms are fixed for the whole period.
