The Costa Blanca Buyer's Legal Due-Diligence Checklist: AFO, Cédula, Catastro and Ley de Costas Explained
By Elia Living ·
Five Legal Checks Every Costa Blanca Buyer Must Make Before Signing
Buying property on the Costa Blanca is as straightforward as the legal process allows it to be — and in the Valencian Community, that process has a handful of specific checks that differ meaningfully from other parts of Spain. Five of them catch buyers out repeatedly: planning status (the issue loosely called AFO elsewhere in Spain), the licencia de ocupación that replaces the cédula de habitabilidad in Valencia, Catastro–Land Registry discrepancies, Ley de Costas coastal restrictions, and inherited charges registered against the property.
None of these is insurmountable. Each is entirely verifiable before contracts are signed. What follows is what to look for, why it matters, and who carries out each check.
1. Planning Status: Fuera de Ordenación and the Valencian Equivalent of AFO
Many buyers arrive on the Costa Blanca asking about the "AFO certificate." In strict terms, the Asimilado Fuera de Ordenación (AFO) is an Andalusian administrative certificate that has no equivalent procedure in the Valencian Community. The underlying concern — a building constructed without the correct planning licence — is equally relevant here.
In Valencia, planning compliance is governed by LOTUP (Ley 5/2014 de Ordenació del Territori, Urbanisme i Paisatge). Once the enforcement period has expired (15 years from the date construction finished in most cases), a municipality cannot order demolition, but the building remains in a state of fuera de ordenación: it can be used and sold, but structural extensions and certain renovations are restricted.
For buyers, the essential check is this: does the Land Registry entry for the property match what is physically on site? If a pool, garage conversion, or outbuilding was added after the original licencia de obra, it may not be formally registered — and the legal risk transfers to you at completion. Your lawyer should cross-reference the nota simple from the Registro de la Propiedad with the Catastro record and, where possible, a site inspection, to identify anything unregistered.
2. The Licencia de Ocupación: Valencia's Answer to the Cédula de Habitabilidad
Foreign buyers frequently ask for the cédula de habitabilidad — the habitation certificate that remains the standard document in regions such as Catalonia. In the Valencian Community, the cédula has been superseded by the licencia de ocupación (for new builds: licencia de primera ocupación; for resale properties: licencia de segunda ocupación), issued by the local ayuntamiento.
This certificate confirms the property meets minimum habitability standards: a minimum usable area of around 36 m², ceiling heights of at least 2.50 m in principal rooms, and direct natural light and ventilation in all bedrooms and living areas. Without a valid licencia de ocupación, the notary may decline to authorise the deed, connecting utilities to the property becomes legally problematic, and most Spanish mortgage lenders will not proceed.
Sellers are obliged to provide one at completion. If the existing certificate has expired or was never obtained — not uncommon in older rural or coastal properties — renewal must be arranged before the escritura is signed. Budget time for this: the ayuntamiento processing period can run to several weeks.
3. Catastro vs. Land Registry: When Two Official Records Disagree
Spain maintains two separate official property databases. The Catastro is a fiscal and mapping register used to calculate IBI (council tax) and other property taxes. The Registro de la Propiedad is the legal record of ownership, charges, and boundaries. In an ideal world they agree. On the Costa Blanca, they frequently do not.
Common reasons include: an extension built and taxed by the Catastro but never formally registered in the Registro; a boundary adjustment following a neighbouring sale; a terrace enclosed without a planning licence that appears on the Catastro's aerial survey. Discrepancies are not automatically a deal-breaker, but they must be formally resolved before purchase.
The consequences of ignoring them are significant: future planning applications can be blocked, mortgage re-financing becomes difficult, and historical tax underpayments may be claimed back from the new owner with interest by the Agencia Tributaria. Your lawyer should obtain both the nota simple and the certificado catastral descriptivo y gráfico and compare them item by item before you proceed past the arras stage.
4. Ley de Costas: Coastal-Zone Restrictions Every Buyer Must Check
Spain's Coastal Law (Ley 22/1988 de Costas) established three distinct zones along the entire coastline:
| Zone | Distance inland | Key restriction |
|---|---|---|
| Dominio Público Marítimo-Terrestre | The beach, surf zone and tidal reach | No private ownership; concessions only |
| Servidumbre de Protección | 100 m (20 m in some urban areas) | New construction prohibited; renovations require Demarcación de Costas approval |
| Zona de Influencia | Up to 500 m | Planning scrutiny; restrictions on height and density |
Properties built before 1988 on officially classified urban land within the 100-metre protection zone may exist legitimately, but they hold an administrative concession — not full freehold ownership. Concessions originally ran for 30 years; those that renewed when the first term expired now run until approximately 2063. Extensions, enclosed terraces, and pools added within the protected strip after 1988 are technically subject to demolition proceedings.
Critically, Spanish notaries do not verify Ley de Costas compliance as part of their standard process. Buyers should ask their lawyer to request a formal certificate from the Demarcación de Costas confirming the property's zone status, and to check whether any expediente de deslinde (boundary revision proceeding) is active — a proceeding that can redefine what falls within the public domain. Both Jávea and the wider Costa Blanca North coastline have properties where this check is essential.
5. Inherited Charges: What the Nota Simple Actually Reveals
Under Spanish law, certain debts follow the property rather than its previous owner. When you complete a purchase, you may inherit:
- Outstanding IBI arrears — up to four years can be recovered from the property itself
- Unpaid community-of-owners fees — the community holds a preferential legal claim on the property
- Utility debts registered against the address
- Mortgages or embargoes (legal attachments) lodged at the Registro de la Propiedad
The nota simple from the Registro is the starting point, but it must be requested as close as possible to the signing date — its information reflects the position on the day it is issued only. Your lawyer should also request a certificado de deudas from the administrator of the community of owners confirming no fees are outstanding.
These checks are not bureaucratic formalities. On more than one occasion, buyers have completed on a Costa Blanca property only to discover a community embargo that was lodged in the days between the nota simple check and the notary appointment.
How a Buyer's Agent Co-ordinates the Process
These five checks are standard practice for any competent conveyancer in the Valencian Community. The difference between a smooth purchase and a stressful one is usually co-ordination: instructing the right independent lawyer at the right moment, requesting each certificate in the correct sequence, knowing which result warrants renegotiation versus refusal, and having someone fluent in both the language and the process working exclusively for you.
That is the role of a dedicated buyer's agent in Jávea: no conflict of interest, no seller to represent, and a clear brief to get you into the right property on the right terms with every legal box ticked.
The Costa Blanca is, as the numbers consistently show, one of Europe's most resilient and sought-after property markets. Carrying out these five checks is not a reason for hesitation — it is what transforms a promising property into a purchase you can enjoy with complete confidence for years to come.
Frequently asked questions
Is the AFO certificate required in the Valencian Community?
No. The AFO (Asimilado Fuera de Ordenación) is specific to Andalusia and has no direct equivalent in Valencia. The Valencian Community uses LOTUP to govern planning compliance. Your lawyer carries out the equivalent checks via the nota simple, Catastro records, and town-hall planning certificates — a different procedure, the same peace of mind.
What replaces the cédula de habitabilidad in the Valencian Community?
The licencia de ocupación — either primera ocupación for new builds or segunda ocupación for resale properties — issued by the local ayuntamiento. Sellers must provide a valid one at completion. The notary will typically require it, and mortgage lenders will not proceed without it.
Does the Ley de Costas affect properties in Jávea and Moraira?
Yes. Both towns have significant stretches of coastline, and properties near the sea may fall within the 100-metre protection zone. Before proceeding, your lawyer should request a certificate from the Demarcación de Costas confirming the property's zone and check whether any deslinde (boundary revision) proceedings are active.
What if the Catastro and Land Registry records disagree?
The discrepancy must be formally corrected — via an expediente de rectificación at the Registro — before you complete. Unresolved discrepancies can block future planning applications, complicate mortgage re-financing, and make the property harder to resell. It is not unusual for sellers to be unaware of the mismatch; resolving it is a routine condition to include in the arras contract.
Can a buyer inherit the previous owner's unpaid IBI?
Yes. Spanish law allows the municipality to recover up to four years of outstanding IBI directly from the property — meaning from its new owner. Your lawyer will request an IBI certificate from the ayuntamiento confirming whether any arrears exist and, if so, will negotiate their clearance as a condition of purchase.
Do I need a buyer's agent as well as a lawyer for these checks?
They are complementary roles. Your lawyer carries out the legal verification; a buyer's agent selects the property, manages negotiation, co-ordinates the legal team, and acts solely in your interest throughout. On the Costa Blanca, where many selling agents represent vendors, having someone on your side of the table — and the table only — makes a measurable difference.
