Buying a coastal home in Spain: check the Coastal Law before a deposit

Before paying a reservation or arras deposit for a Spanish coastal home, identify the exact registered property and parcel, then match them to the approved coastal boundary, Land Registry evidence and any current concession or authorisation. If ownership, the affected coastal zone, or the rights to use and alter the property remain unclear, make them written purchase conditions. Do not value a possible future regularisation as though it were already approved.

This is a focused Coastal Law check, not an alternative to the complete Spanish home-buying workflow. It should answer three separate questions: where the home lies, what interest the seller can transfer, and what the present records support.

Translate the Spanish coastal terms before judging the listing

Dominio público marítimo-terrestre (DPMT) means the State maritime-terrestrial public domain. The deslinde is the official delimitation procedure and approved boundary for a stretch of coast. A private plot may remain outside DPMT while being affected by statutory coastal servitudes; an occupation inside public domain may depend on an administrative title. “Beachfront” is not a legal classification.

The servidumbre de protección is the protection servitude on adjoining private land. Spain's Coastal Law, Ley 22/1988, gives a general 100-metre rule measured landward from the inner limit of the seashore, with provisions for extension, certain reductions and transitional cases. That does not make every house within 100 metres unlawful. The approved delimitation, historic position and building file must be examined together.

The servidumbre de tránsito preserves coastal transit for pedestrians and surveillance or rescue vehicles. The servidumbre de acceso al mar protects public access to the sea. They are not the same as a private right of way between neighbouring properties. Ask which route affects the home and what evidence defines it.

Bridge the advertisement to the approved boundary

Start with identifiers, not a beach name. Collect the full address, cadastral reference, registered-property number and a plan showing the land and building offered. Identify a parking space, garden, terrace or path separately if it matters to the decision. A portal pin may be approximate.

MITECO, Spain's environment ministry, provides digital DPMT delimitation lines and access to the coastal viewer. Use the viewer as an initial screen and retain the date and layers consulted. Then obtain the approved deslinde plan and relevant file. A screenshot is not a property-specific certificate.

If plans use different identifiers or geometry, ask a suitable professional to relate the registered property, cadastral parcel, physical building and coastal lines. The boundary and cadastral evidence guide explains why Registry and Cadastre serve different purposes. A sales-plan overlay is not a substitute for a traceable comparison with the approved record.

Give each document one job, and no more

A nota simple is an informative Land Registry extract. The Spanish Association of Registrars' property service distinguishes it from registry certification, which has public-document evidential status. Use current evidence to identify the holder and burdens, but do not ask it to perform the work of the coastal file.

If papers refer to a concesión (concession) or autorización (authorisation), obtain the complete title and later decisions. Record its holder, location, purpose, term and conditions. MITECO's DPMT management page explains that occupation needs the corresponding enabling title and warns that its uses register may contain errors or omissions that should be checked with the competent coastal service. Under the State rules for using DPMT, authorisations are personal and non-transferable between living parties, apart from the statutory exception for discharges; an inter vivos concession transfer is valid only after the Administration recognises that the buyer meets the concession conditions. Neither title is private freehold or passes merely because the property deed is signed.

Separate State, regional, municipal and technical checks

The State approves DPMT delimitations and manages titles for occupying DPMT under the Coastal Law. On private land within the protection servitude, permitted uses require authorisation from the corresponding autonomous-community authority, while the municipality applies planning rules and municipal licences. You may also need the Servicio Periférico de Costas, the State's provincial or territorial coastal office, to identify the file. Confirm the competent office and procedure for the address.

A municipal works licence does not extinguish a DPMT issue, and a coastal title does not prove that an extension complies with planning. If extra floor area is involved, run the separate extension, Cadastre, Registry and municipal-file checks. Spain's General Coastal Regulation, Real Decreto 876/2014, develops registry checks, servitudes, authorisations and transitional provisions. Existing buildings may have a historic or transitional position affecting proposed works. Ask about your defined project, not whether renovation is “generally possible”.

Keep physical investigation separate. A pre-purchase building inspection can consider corrosion, damp and maintenance but does not interpret title. Check occupation evidence through the guides to the first-occupation licence and habitability certificate. Screen flood risk independently: a home outside DPMT is not automatically free of coastal, surface-water or drainage hazards.

Compare two fictional homes without hiding gaps

Home A is a fictional older seafront apartment. Its current registry extract identifies the unit and seller, and a professional has matched the building and cadastral parcel to the approved deslinde. The records explain the private property's servitude position. A structural inspection and municipal review of an enclosed terrace remain outstanding. The purchase is not cleared, but each open item has a source and consequence.

Home B is a fictional detached house with a better view. Its file has a circle drawn on a viewer screenshot, but no match to the approved plan. The advertised garden reaches towards the promenade, yet its legal basis is unclear. The agent mentions an old concession without supplying holder, conditions or term. A nota simple cannot fill those gaps.

The point is not that A is “legal” and B is “illegal”. A has a documented foundation plus open checks; B lacks evidence needed to classify what is offered. If you are also choosing between places, use the north-versus-south Costa Blanca guide for location trade-offs, then return to each address for coastal due diligence.

Choose proceed, condition or stop before the deposit

• Identify every registered property, cadastral parcel, building and ancillary space offered.
• Locate the stretch in the viewer, then obtain the approved delimitation plan and file.
• Match the property to DPMT and the protection, transit and sea-access servitudes.
• Obtain current Registry evidence and investigate relevant entries or mismatches.
• Read every concession or authorisation in full, including holder, term and conditions.
• Allocate State, regional, municipal and technical questions to the correct evidence.
• Define intended use and works, and obtain a property-specific response.
• Put essential unresolved results, deadlines and consequences into the purchase terms.

Proceed when identity, applicable lines and titles match. Make the purchase conditional when a defined document or decision must arrive before you are bound; agree the wording with your legal adviser. Stop when the seller's interest cannot be identified, an essential title is missing, the required use is unsupported or the deal depends on uncertain regularisation.

Do not assume a standard reservation or arras agreement gives a general cooling-off right. Use the reservation and arras guide to prepare questions about the actual draft. To organise the project, tell us the municipality, purchase stage, available reference, coastal papers supplied and the use or works you need to preserve. Avoid identity documents in the first message. This defines the next checks without promising consent, concession transfer or regularisation.
