Signing a lease in Spain is rarely just showing your passport and paying the deposit. Before handing over the keys, the landlord or agency wants to be sure of one very specific thing: that you will pay every month. To believe it, they ask for paperwork. When it comes from another country and in another language, the question we hear every week appears — do you have to translate it, and does it have to be a sworn translation?
Let us be honest from the start, because there is a lot of confusion online: no rule obliges you to have documents sworn-translated in order to rent a home. Renting is not an administrative procedure; it is a contract between private parties. What exists is market practice, and that practice shifts depending on who is on the other side of the table.
What a landlord asks for before trusting you
A landlord letting a flat does so, in practice, almost blind: the law gives them no register to check your solvency. That is why the custom of asking for a small financial file has taken hold. The usual items:
- Payslips from the last few months (normally three).
- Employment contract, to see the type of contract and your seniority.
- Income tax return for the last year.
- Recent bank statements.
- Sometimes a guarantor or an additional guarantee.
When you arrive from abroad, all of these documents exist, but they are in English or French, with company names, salary line items and formats a Spanish landlord cannot always read. That is where translation comes in.
Sworn or simple? It depends who reads it
This is the important part, and the one almost nobody explains clearly. Not every situation calls for the same thing:
Often a simple translation is enough. If the landlord only wants to understand your payslip and contract to form a view, a plain, well-made translation does the job. They are not filing it anywhere official; it just helps them decide. Forcing a sworn translation here is spending more than you need.
A sworn translation makes sense when the document will carry weight before a formal third party. Two clear cases: a guarantee signed before a notary or forming part of a deed, and a rent-default insurance policy, which we cover just below.
The difference between the two types is not quality but legal value: a sworn translation is signed and stamped by a MAEC-accredited translator and attests that the content faithfully matches the original. If you are unsure which you need, we go into it in sworn versus certified translation.
Rent-default insurance: where sworn pays off
More and more landlords will not let a flat without rent-default insurance. That policy changes the rules, because the decision-maker is no longer the landlord going on instinct: it is an insurer that runs a formal solvency assessment before accepting a tenant.
That assessment analyses real documentation: the latest payslips, the employment contract (weighing whether it is permanent and how long you have held it), the last income tax return and the ratio between your income and the rent. As a rule, the insurer wants net income around two and a half times the rent, with rent not exceeding roughly 40% of what you earn.
Here a poorly presented foreign document is a real problem. If the analyst cannot understand your French bulletin de paie or your British contract of employment, they cannot score it, and an application that cannot be assessed gets rejected. A sworn translation of those payslips and that contract closes the file: figures, line items and dates in Spanish, signed by a translator who vouches for their accuracy.
The newcomer with no track record
There is one situation where translating well is not enough on its own: the expat who has just landed. You may have an excellent contract, but you have no history in Spain, you appear in no solvency registers, and your reference bank is in another country. Many landlords read that as risk, even when your numbers are strong.
The usual ways out lean on reinforcing the guarantee rather than adding paperwork:
- More months of deposit or an additional guarantee. For a primary residence, the law allows additional guarantees that, in leases of up to five years, may not exceed two months' rent on top of the legal one-month deposit.
- A bank guarantee, which is worth having sworn-translated when it accompanies foreign documentation and is formalised properly.
In these cases, a tidy pack — employment contract, payslips and, if requested, statements — translated clearly makes your lack of history weigh less: what you can prove is on full display, with no "I don't understand it" excuses.
In short: what you end up translating
To rent, the block that usually goes for translation is the solvency file: employment contract, payslips and income tax return, and often the bank statements. If it is only for the landlord's eyes, a simple translation does the job; if an insurer, a notary or a guarantee is involved, a sworn one spares you rejections. And no translation, however good, replaces proving sufficient income: translate so the papers are understood, not expecting them to work magic. You can see the documents we typically translate in our document catalogue.
At Textualia we translate that full file from English and French into Spanish, with the right employment and tax terminology, delivered as an electronically signed PDF. If the landlord or insurer ends up asking for a physical copy or a sworn version, it is ready without redoing anything. Renting is already enough of a marathon; a paper in another language should not be what stops you.
