Your Spanish property’s paperwork, explained: escritura, IBI, valor catastral and friends

Spain doesn't send you a folder when you buy a property; it hands you a stack of papers in a language of their own — escritura, nota simple, IBI, cédula — and then, years later, demands exactly one of them at exactly the wrong moment. If you own from abroad, that stack usually lives in a drawer in another country, or in a lawyer's office you've lost touch with.

Here is what each document actually is, where to find it, and when someone will ask for it.

The stack, at a glance

Escritura vs the Registro — the distinction that confuses everyone

The escritura is the deed you signed at the notary. But Spanish law gives third-party force to the Registro de la Propiedad — the Land Registry entry made after the notary. What people actually check is the registry, via a nota simple: a short extract, ordered online from the official registrars for a few euros, showing who owns the property and any charges on it. Keep your escritura safe, but when a lawyer or agent asks "for the paperwork", a fresh nota simple is usually what they mean.

IBI and the valor catastral — the receipt that's secretly a tax input

The IBI (Impuesto sobre Bienes Inmuebles) is the local rates bill, usually paid by direct debit and promptly forgotten. Don't file it away unread: it carries your valor catastral, the administrative value of the property held by the Catastro — and that number is the basis of the Modelo 210 tax every non-resident owner owes each year, even on an empty home. One photograph of one receipt answers the question your tax filing will ask every year.

CEE — the certificate with a quiet expiry

The certificado de eficiencia energética is required when you sell or advertise a letting, and it expires: ten years of validity, five if the rating is G (Real Decreto 390/2021). It's the classic event-gate document — nobody asks for it for a decade, then a sale hangs on it while you wait for an assessor.

Cédula de habitabilidad — depends entirely on where the property is

The habitability certificate is regional. In Cataluña and the Balearics it's a hard gate — you can't contract utilities, sell or let without a current one. Madrid abolished it in 2018; other regions sit in between, with different renewal periods. If your property is on the coast or the islands, check the expiry date now rather than at the notary's desk.

NIE — the number, not a document to lose

Your NIE (Número de Identidad de Extranjero) identifies you to every Spanish administration. The paper certificate it arrives on is famously shabby for something so important. Photograph it.

The pattern, and what to do about it

Notice what all of these have in common: Spain enforces at events — the sale, the new tenant, the utility contract, the tax window — not on a calendar. The paperwork is fine until the day it's urgent. The fix is one afternoon: photograph the stack — escritura, latest IBI receipt, CEE, cédula, NIE — and let KeepUp file each one against the property, read the dates that matter, and remind you before the CEE quietly lapses or the Modelo 210 window closes. It's free for one place.
