Navigating the Spanish legal system can feel particularly overwhelming, especially when faced with unfamiliar terminology during an important legal process such as purchasing/selling property, applying for residency or filing tax declarations. Many Spanish legal terms don’t have a direct English equivalent, so to help simplify things, we’ve put together a practical glossary of common Spanish legal terms that expats are most likely to encounter.
NIE (Número de Identidad de Extranjero)
The NIE is a foreigner’s identification number and is necessary for almost all legal and financial activities in Spain. You’ll need it to buy property, open a bank account, pay taxes, set up utilities, work in Spain and even receive parcels at your home! It is effectively your identification number as a non-Spanish national and it is requested on an almost daily basis!
TIE Card (Tarjeta de Identidad de Extranjero)
This is the physical, biometric residence card issued to non-EU/EEA/Swiss citizens who are legally resident in Spain, having either obtained a visa or gone through the Brexit withdrawal process in 2020. If you are a non-EU citizen staying in Spain for more than 90-days in any 180-day period, the TIE is mandatory.
Escritura Pública / Escritura de Compraventa
This is the public title deeds/completion paperwork of a property transaction (purchase, sale, donation, transfer of ownership etc). It is signed in front of a Spanish Notary Public and confirms the legal ownership of the property. Once signed, it must subsequently be registered at the Land Registry (Registro de la Propiedad) to protect your legal ownership.
Notario (Notary)
A Notary in Spain is a qualified public official who ensures that legal documents are correctly drafted, understood by all parties, and legally valid. A Spanish Notary Public does not represent either buyer or seller but instead acts impartially and finalises the transaction.
Registro de la Propiedad (Land Registry)
This is the official registry where property ownership and any charges (such as mortgages or embargoes) are recorded. One would normally request an office copy entry (Nota Simple) from the Land Registry featuring all important details listed about the property (ownership, size, boundaries, and any registered debts or charges).
IBI (Impuesto sobre Bienes Inmuebles)
The IBI is a local property tax paid annually to the town hall. It is similar to council tax in the UK and is calculated based on the property’s cadastral value (valor catastral).
Basura
The Basura tax is the local refuse collection tax. It covers rubbish removal and waste services and is usually billed annually or biannually by the local authority.
Comunidad de Propietarios
If your property is part of an apartment block or urbanisation, you automatically become a member of the Community of Property Owners. The community manages and maintains communal areas such as gardens, pools, lifts, and shared spaces. Community fees (gastos de comunidad) are usually paid monthly or quarterly to cover communal expenses. The amount varies from urbanisation to urbanisation, depending on facilities available and how large communal areas are.
Plusvalía Municipal
This is a local tax paid to the town hall when a property is sold. It is calculated on the increase in the value of the land over time and is usually paid by the seller, unless otherwise agreed.
IRPF (Impuesto sobre la Renta de las Personas Físicas)
IRPF is Spanish income tax paid by residents. If Spain is your main country of residence, you are required to file an annual income tax return (Declaración de la Renta – see below).
Declaración de la Renta
This is the annual income tax return filed by Spanish residents, usually between April and June for the previous tax year.
Impuesto sobre la Renta de No Residentes
This is the non-resident income tax declaration form. Even if you do not live in Spain, owning property there obliges you to submit a non-resident tax declaration each year, normally in December. This declaration is retrospective and is calculated on the year prior to the current year. E.g. in December 2026 you will be filing for the year 2025.
Poder Notarial (Power of Attorney)
A Power of Attorney allows someone else (such as a lawyer or trusted individual) to act on your behalf in legal or financial matters. This is commonly used by expats who cannot be physically present in Spain for property transactions.
Catastro / Valor Catastral
The Catastro is the official property valuation registry, and the valor catastral is the administrative value assigned to a property. This value is used to calculate certain taxes, including IBI.
Empadronamiento (Padrón)
This is the registration of your address with your local town hall. Being registered on the padrón is often required for accessing public services, healthcare, schooling, and residency applications. N.B. Padron certificates are only valid for 3 months at a time!
