Spain remains one of the most popular destinations for international property buyers, offering a combination of lifestyle appeal, established legal infrastructure, and a wide range of price points from Costa Blanca apartments to Marbella villas. The legal process, however, contains hazards that are specific to Spain and routinely catch buyers unaware — particularly around illegal constructions, community debts, and tourist licence compliance.
This guide covers every legal check that should be completed before signing a private purchase contract (contrato de arras) or a full escritura pública.
Obtain Your NIE Before You Start
The NIE (Número de Identificación de Extranjero) is a non-negotiable requirement for any property purchase in Spain. Without it you cannot:
- Sign a purchase contract at a notary
- Open a Spanish bank account to transfer purchase funds
- Pay Spanish property taxes
- Apply for a Spanish mortgage
The NIE application process typically takes between a few days and several weeks depending on the method (consulate abroad vs in-person in Spain). Allow adequate time — a delay on your NIE can delay the entire transaction.
You will also need a Spanish bank account to receive the signed deeds and pay ongoing taxes. Open this as early as possible.
Appoint an Independent Spanish Lawyer
A qualified, independent Spanish lawyer (abogado) is essential for any property purchase. They must be:
- Registered with a Spanish Bar Association (Colegio de Abogados)
- Independent of the estate agent and the vendor
- Fluent in your language and in Spanish legal procedure
- Experienced specifically in Spanish property transactions
Do not use a lawyer recommended by the agent or developer without independent vetting; conflicts of interest are common. Your lawyer will conduct all the searches described below and should review every document before you sign anything.
Legal fees for a standard residential purchase typically range from 1–1.5% of the purchase price plus VAT.
The Nota Simple: Your Starting Point
The Nota Simple is an extract from the Registro de la Propiedad (Land Registry) and should be the first document your lawyer obtains. It reveals:
- The registered owner's name (must match the vendor)
- The legal description and cadastral reference of the property
- Any charges, mortgages, or encumbrances registered against the property
- Any easements or rights of way
- The registered floor area
Request an up-to-date Nota Simple (ideally within the last 30 days) — registered information can change. If there is a mortgage registered against the property, your lawyer must confirm that it will be discharged at or before completion. In Spain, mortgages are sometimes settled at the notary on the day of signing, with simultaneous discharge registration.
Catastral Value and Floor Area
The Catastro is Spain's property cadastre — a government record separate from the Land Registry. It records the catastral reference number, the plot boundaries, and the floor area for tax purposes.
It is common — particularly in rural areas and older properties — for the catastral floor area to differ from the actual floor area or from what is described in the seller's marketing materials. Discrepancies arise from:
- Illegal extensions built without planning permission
- Terraces or garages counted differently
- Pool or outbuilding additions not registered
Your lawyer should compare the catastral data with the Land Registry entry and with the property as it physically exists. Material discrepancies require resolution before purchase.
Planning Permission and Illegal Constructions
This is one of the most significant risks in the Spanish market — particularly in Andalucía, the Valencia region, and the Canary and Balearic Islands.
Illegal constructions (construcciones ilegales or obras sin licencia) are buildings, extensions, terraces, pools, or outbuildings erected without the required building permit (licencia de obras), or in excess of what the permit authorised. They are widespread, particularly in rural areas.
Why it matters
An illegal construction can be ordered demolished by the relevant municipality or regional authority. If you purchase a property with an illegal element, you inherit the risk of that enforcement action. In some regions, there is a statute of limitations after which enforcement action is time-barred — but this varies by region and is not a reliable protection.
What your lawyer must check
- Building permit (Licencia de Obras) for original construction
- Certificate of Habitation (Cédula de Habitabilidad / Licencia de Primera Ocupación) — confirms the building was completed in accordance with its permit and is legally habitable. Required for resale and for connection to utilities.
- Planning compliance: does the physical property match what the permits authorise?
- For rural land: check whether the property is on protected agricultural land (suelo rústico protegido), where construction is heavily restricted
If the habitation certificate is missing or expired, the vendor may need to obtain a new one or a regularisation certificate before completion. Do not complete without this document in place.
Community of Owners (Comunidad de Propietarios)
Most Spanish flats, and many villa complexes, are subject to the Ley de Propiedad Horizontal, which governs the shared ownership of common areas. The community of owners — all unit-holders jointly — manages the building, pays for maintenance, and levies an annual fee (cuota de comunidad).
Community debts attach to the property
Under Spanish law, community of owners debts for the current year and the previous three years attach to the property, not to the vendor personally. If the vendor has not paid their community fees, you as buyer will inherit that liability.
Your lawyer must obtain a certificate from the administrator of the comunidad confirming that the property has no outstanding community fee arrears, including any special levies (derramas) for major works.
Community minutes review
Request the minutes (actas) of the last two to three years of community meetings. These will reveal:
- Planned major works (re-roofing, lift replacement, facade renovation) and whether a special levy has been agreed
- Any ongoing disputes with the developer or between owners
- Whether the building has insurance, and whether there are any outstanding insurance claims
- The overall financial health of the community
IBI Arrears
IBI (Impuesto sobre Bienes Inmuebles) is the Spanish annual property tax, levied by the local municipality. Unpaid IBI can result in a registered charge against the property. Your lawyer must obtain confirmation from the local ayuntamiento (council) that all IBI payments are current. Request receipts for the last five years.
Tourist Licence Compliance
If you intend to let the property on a short-term or tourist basis (Airbnb, Booking.com, etc.), verify whether:
- The property is in a zone that permits tourist lettings under current regional rules
- The property holds or is eligible for a valid tourist licence
- The community of owners has not voted to prohibit tourist lettings
Spain's regions have adopted increasingly restrictive approaches to tourist rentals. As of 2026, several municipalities — including Barcelona — have substantially restricted new tourist licence grants. Verify the position specifically for the municipality and property you are considering.
Common Legal Pitfalls in Spain
| Pitfall | How to Avoid |
|---|---|
| Illegal construction ordered for demolition | Check building permit and habitation certificate for all structures |
| Undeclared extensions on catastral records | Compare catastral floor area to physical property |
| Inherited community fee arrears | Obtain zero-arrears certificate from comunidad administrator |
| Unregistered easement or right of way | Full Nota Simple and title search before purchase |
| IBI arrears charged against property | Confirm current payment with municipality |
| Rural land with construction restrictions | Verify zoning before purchasing rural property |
| Missing habitation certificate | Do not complete without this document |
| Tourist licence not available | Verify regional rules before purchasing for short-let income |
Transaction Costs to Budget
- Transfer tax (ITP): 6–10% of purchase price (resale properties; rate varies by region)
- VAT (IVA) + Stamp duty (AJD): 10% + 0.5–1.5% (new-build properties)
- Notary fees: Regulated by a sliding scale; typically €600–2,000
- Land Registry fees: Typically €400–1,200
- Legal fees: 1–1.5% of purchase price
- Mortgage costs (if applicable): Arrangement fees, valuation, insurance
Budget total transaction costs at approximately 10–13% for a resale property in addition to the purchase price.

Frequently asked questions
What is an NIE and why do I need one?
The NIE (Número de Identificación de Extranjero) is a tax identification number issued to foreign nationals in Spain. You cannot complete a property purchase, open a Spanish bank account, or pay Spanish taxes without one. Apply at a Spanish consulate in your home country or at a police station in Spain, ideally before you start viewing properties.
What is a Nota Simple?
A Nota Simple is an extract from the Land Registry (Registro de la Propiedad) that shows the registered owner, the legal description of the property, and any charges, mortgages, or encumbrances registered against it. It is an essential due diligence document — your lawyer should obtain one as a first step.
Is Spain's Golden Visa still available?
No. Spain closed the property-based Golden Visa route in April 2025. Investors who completed eligible purchases before that date retain their existing visas, but new applications based on residential property investment are no longer accepted.
What taxes apply when buying property in Spain?
For resale properties: Impuesto sobre Transmisiones Patrimoniales (ITP/transfer tax) at rates that vary by region, typically 6–10%. For new-build properties: IVA (VAT) at 10% plus Impuesto sobre Actos Jurídicos Documentados (AJD/stamp duty) at 0.5–1.5%. Additional costs include notary, Land Registry, and legal fees.
