A sea view, a sunny terrace, and an attractive asking price can make an apartment in Costa Blanca feel like an easy decision. But the legal checks before buying an apartment are where a safe purchase is really won or lost. In Spain, a property can look perfectly maintained while carrying unpaid community fees, planning issues, an undisclosed tenant, or restrictions that do not match your plans for rentals or renovations.
For international buyers, the key is not to become an expert in Spanish property law overnight. It is to make sure an independent professional verifies the right documents before you commit a deposit or sign a private contract. The checks below are especially relevant for resale apartments in Torrevieja, Orihuela Costa, Murcia, and the wider Costa Blanca, where many homes are part of larger communities.
Legal Checks Before Buying an Apartment: Start With Ownership
The first question is simple: does the seller legally own the apartment and have the right to sell it? Your lawyer should obtain a recent Nota Simple from the Land Registry. This document identifies the registered owner, describes the property as it appears in the registry, and shows recorded charges or restrictions.
The Nota Simple can reveal a mortgage, embargo, court order, right of use, or other registered claim. A mortgage does not necessarily stop a sale. It may be paid off from the seller's proceeds at completion, but this must be clearly arranged in the purchase paperwork and handled correctly before the deed is signed.
The registry details should also be compared with the seller's title deed, known as the escritura, and the actual apartment. Pay attention to the address, floor, apartment number, square meters, storage room, parking space, and any terrace or roof rights. A parking space advertised with an apartment may be included in the deed, separately registered, or merely used informally. Those are very different situations.
Compare the Registry With the Cadastre
Spain has both the Land Registry and the Cadastre. The Land Registry records ownership and legal rights, while the Cadastre is primarily used for tax and mapping purposes. Their descriptions do not always match, particularly in older developments or properties that have been altered over time.
A small difference in stated size is not automatically a problem. Registry and cadastral measurements can be calculated differently, and marketed square meters may include common areas. A more serious concern is an enclosed balcony, converted storage room, altered layout, or additional terrace area that does not appear in the legal documents.
If the apartment has been renovated, ask whether the work required permission and whether it was obtained. Internal cosmetic work is different from removing walls, enclosing terraces, changing façades, or modifying plumbing and electrical systems. The answer may affect future resale, insurance, community disputes, and your ability to carry out further work.
Confirm Licenses and Planning Status
A property needs to be legally suitable for residential use. Depending on the property, municipality, and age of the building, your lawyer may check the first occupancy license, a second occupancy license, or equivalent documentation. These documents can matter for utility contracts, mortgages, and proving that the home was authorized for habitation.
For an apartment in an established community, it is also sensible to verify that the building itself is not affected by known planning or urban discipline issues. This is particularly relevant where terraces have been enclosed, communal areas have been privatized, or a building has a long history of unapproved changes.
New-build purchases require additional checks. You will want to see the building license, the developer's legal details, insurance or guarantees connected to advance payments where applicable, and the certificate allowing first occupation. Do not assume that a new property is lower risk simply because it has never been lived in. The documents and timelines are different, but the due diligence is still essential.
Check Community Debts and Rules
Most apartments in Spain are governed by a community of owners. The community maintains shared areas and collects regular fees for items such as cleaning, lifts, pools, gardens, insurance, security, and repairs. Before completion, obtain a certificate from the community administrator confirming whether the seller is up to date with community payments.
This is not a minor formality. Under Spanish rules, a buyer can become responsible for certain unpaid community charges linked to the property. A clear certificate, requested close to the signing date, protects against unpleasant surprises.
You should also ask for the community statutes, recent meeting minutes, annual budget, and information on planned major works. A modest monthly fee can be manageable, but a pending façade repair, lift replacement, structural work, or pool renovation may create a substantial extra assessment. Minutes can also reveal recurring disputes about noise, parking, holiday rentals, pets, or use of communal spaces.
If Rental Income Is Part of Your Plan
Do not rely on a listing description that says an apartment is ideal for holiday rentals. Tourist rental rules vary by region and municipality, and community rules may limit or prohibit this activity. In the Valencian Community, regulations and registration requirements can change, while some communities apply their own restrictions or approval procedures.
Long-term rentals are usually a different proposition, but they also come with legal obligations and practical considerations. Before buying, confirm whether there is an existing tenant, whether a lease remains in force, and what rights the tenant has. A tenant does not always need to leave simply because the apartment is sold.
Verify Taxes, Utilities, and Other Property Debts
Your legal review should include the latest IBI receipt, which is the annual local property tax. It confirms the cadastral reference and helps identify whether local taxes are paid. Also ask about waste collection charges, utility bills, and any other municipal charges that may be tied to the home.
Utility contracts should be checked for outstanding balances and practical transfer requirements. If electricity or water has been disconnected for a long time, reconnection may take time and could require updated technical paperwork. This is worth knowing before you plan a quick move-in, renovation, or first holiday visit.
For properties being sold from an inheritance, divorce, company ownership, or under power of attorney, extra care is needed. Every person or entity with legal authority must be properly identified, and the documentation must support the transaction. These sales can proceed smoothly, but they should never be rushed on the strength of verbal assurances.
Do Not Pay a Deposit Before the Documents Are Checked
Many buyers first sign a reservation agreement to take an apartment off the market. This can be useful, but read the terms carefully. A reservation payment should state what it is for, who holds the money, when it is refundable, and what happens if legal checks uncover a material problem.
The next stage is often an arras contract, commonly used to set the price, completion date, deposit amount, and consequences if either party withdraws. Not all arras clauses have the same legal effect. The wording matters, as does the list of conditions attached to the purchase.
A well-prepared contract should identify the property precisely, state which fixtures and furniture are included, require delivery free of debts and occupants unless agreed otherwise, and set out how any mortgage cancellation will be handled. If your purchase depends on finance, a license, a satisfactory legal review, or a specific completion date, those points should be addressed before you transfer significant funds.
Prepare for the Notary, But Do Not Treat It as Your Lawyer
The final deed is signed before a Spanish notary. The notary checks identity, formalities, and legal elements of the transaction, then records the sale in the public deed. This is an essential safeguard, but the notary is not your personal buyer representative and does not replace independent legal advice.
Foreign buyers will usually need an NIE number, valid identification, and a Spanish bank account or an accepted payment method for completion. If you cannot attend, a properly drafted power of attorney can allow a trusted representative to act for you. Remote buying is possible, but it makes early document checks and clear communication even more valuable.
Buying an apartment in Spain should feel exciting, not uncertain. The right home is more than a good location and a realistic price – it is a property whose ownership, debts, community position, and legal status have been checked before you become committed. At Buy and Sell in Spain, we encourage buyers to treat due diligence as part of choosing the home, not as paperwork left until the end. A careful start gives you more confidence to enjoy everything that comes after the keys are handed over.
