What Are the Legal Steps to Buying a Home in Costa del Sol? (2026 Guide)

Buying property in Costa del Sol offers British buyers the chance to own a home in one of Europe's most desirable coastal regions. The legal process differs significantly from UK property transactions, requiring careful navigation of Spanish property law, tax obligations and administrative procedures.

This guide walks through each legal step, from obtaining your initial documentation to completing the final deed of sale and beyond.

Understanding the Costa del Sol Property Market

Costa del Sol remains a popular destination for UK property buyers, offering Mediterranean climate, established expat communities and strong rental potential. The region stretches along Andalusia's southern coast, encompassing popular towns including Marbella, Estepona, Fuengirola and Málaga.

Spanish property law operates differently from the UK system. Transactions typically take longer, involve more upfront documentation and require interaction with Spanish notaries, land registries and tax authorities. Understanding these differences before starting your search prevents costly delays and ensures proper legal protection.

The total purchase cost extends beyond the advertised property price. Buyers should budget for property transfer tax, legal fees, notary charges, land registry fees and other associated costs, which typically add 10-12% to the purchase price.

UK vs Spanish Property Purchase: Key Differences

The table below highlights fundamental differences between UK and Spanish property transactions:

This comparison demonstrates why Spanish property purchases demand more active buyer involvement and longer timescales than most UK transactions.

Complete Cost Breakdown for Costa del Sol Property Purchase

Understanding all costs is essential for accurate budgeting. The table below shows every fee and tax payable when buying a resale property in Andalusia, with a worked example based on a property priced at €350,000 (approximately the median price point for coastal Costa del Sol properties at the time of writing).

For new-build properties, IVA (VAT) at 10% replaces ITP, and stamp duty (AJD) at 1.5% is payable on the mortgage deed if financing.

This breakdown shows why securing an additional 12% above the advertised price is prudent financial planning for Costa del Sol property purchases.

Step 1: Secure Your NIE Number

The Número de Identidad de Extranjero (NIE) is a legal requirement for any foreign national purchasing property in Spain. This tax identification number is essential for all financial transactions, including property purchases, opening bank accounts and paying Spanish taxes.

You can apply for an NIE through the Spanish Consulate in the UK or at a police station in Spain. The application requires a completed EX-15 form, valid passport, reason for application (property purchase) and the relevant fee. Processing times vary, but applications submitted in the UK typically take between four and six weeks.

Alternatively, you can appoint a lawyer or gestor to obtain the NIE on your behalf using a power of attorney. This option proves useful if you cannot travel to Spain or the consulate during the application process.

Once issued, your NIE remains valid indefinitely and will be required at multiple stages throughout the purchase process.

Step 2: Open a Spanish Bank Account

Opening a Spanish bank account is practically essential for property purchase in Costa del Sol. Most sellers, notaries and local authorities expect payments to be made from Spanish accounts, and having local banking simplifies ongoing property expenses including utility bills, community fees and property taxes.

To open an account, you need your NIE number, valid passport, proof of address (UK address is acceptable initially) and a Spanish mobile phone number. Many Spanish banks now offer non-resident accounts specifically designed for property buyers.

This account will be used to pay the deposit, transfer the balance of the purchase price and pay taxes and fees at completion. You will also need it for setting up direct debits for utilities and ongoing property maintenance costs.

Step 3: Appoint a Spanish Property Lawyer

Engaging an independent Spanish property lawyer who is not connected to the seller, estate agent or developer is one of the most important steps in the purchase process. Your lawyer protects your legal interests, conducts due diligence and ensures the transaction complies with Spanish property law.

Look for a lawyer who speaks fluent English, has specific experience with foreign property purchases and holds professional indemnity insurance. Many UK buyers prefer lawyers who understand both Spanish and UK legal systems.

Legal fees typically range from 1% to 1.5% of the purchase price plus IVA (Spanish VAT at 21%), though fixed fees are also common for straightforward purchases.

Your lawyer should be appointed before you commit to any property or sign any documents, including reservation agreements.

Step 4: Property Search and Reservation

Once you find a property you wish to purchase, the next step is to make a formal offer. If accepted, you may be asked to sign a reservation agreement and pay a reservation deposit, typically between €3,000 and €6,000.

The reservation agreement takes the property off the market for an agreed period (usually two to four weeks) while your lawyer conducts initial legal checks and you arrange finances. This deposit is usually deductible from the final purchase price if you proceed, but may be forfeited if you withdraw without valid legal reason.

Ensure your lawyer reviews the reservation agreement before you sign. Some agreements include penalty clauses or conditions that may not be immediately obvious.

Step 5: Due Diligence and Legal Checks

Your lawyer will conduct comprehensive legal checks on the property before you commit to purchase. This due diligence process is critical to identifying any legal issues, debts or restrictions affecting the property.

Essential Documents Your Lawyer Must Review

Your abogado should obtain and thoroughly examine the following documentation:

• Nota Simple Registral: Current Land Registry extract confirming registered owner, property boundaries, square meterage, any mortgages or charges, easements, restrictions or liens recorded against the property
• IBI Receipts (Impuesto sobre Bienes Inmuebles): At least three years of property tax receipts proving payment is current and showing assessed cadastral value
• Community Fee Status: Certificate from community administrator (if applicable) confirming all fees are paid to date and no special assessments pending
• Building Permits for Extensions/Renovations: Licencia de obras for any structural changes, pool additions or extensions beyond the original build
• AFO Certificate (Agencia de Protección del Medio Ambiente): Environmental certificate confirming property is not on protected land (required in some areas)
• Debts Certificate: Certificate from community, town hall and utility companies confirming no outstanding debts
• Habitation License (Licencia de Primera Ocupación/Cédula de Habitabilidad): Proof the property was legally approved for residential occupation
• Cadastral Certificate: Official plan showing the property boundaries match the registered description
• Energy Performance Certificate (Certificado de Eficiencia Energética): Legally required for all property sales
• Last Escritura (Title Deed): Previous deed of sale showing chain of ownership and any conditions or restrictions

Critical Red Flags Your Lawyer Should Investigate

During the review process, your lawyer should alert you immediately if they discover:

• Discrepancies between the nota simple registered size and actual built area, which may indicate illegal construction
• Outstanding community fees or local taxes, as these pass to the new owner unless settled before completion
• Building works completed without proper licences, which could result in demolition orders or substantial fines
• Mortgages or charges registered against the property that the seller has not disclosed
• Embargo or court orders affecting the property due to seller's debts
• Property located partially or fully on rustic land where residential building is restricted
• Missing habitation license, which makes the property technically illegal for residential occupation
• Undeclared rental income or tourist license issues that could create tax liabilities

This stage typically takes two to three weeks. Never proceed to contract signing until your lawyer confirms all checks are satisfactory and all red flags have been resolved or appropriately addressed in the contract terms.

Step 6: Sign the Private Purchase Contract (Arras)

Once legal checks are complete and you are satisfied with the property, you will sign the private purchase contract, known as the contrato de arras or arras contract. This legally binding agreement commits both parties to the sale.

The arras contract includes the full terms of the sale, final purchase price, completion date (typically one to three months from signing), list of items included in the sale and conditions for either party to withdraw. You pay a deposit at this stage, usually 10% of the purchase price.

There are three types of arras contracts under Spanish law, each with different legal consequences if either party withdraws. The most common for property purchases is arras penitenciales, which allows either party to withdraw: the buyer forfeits the deposit if they withdraw, while the seller must return double the deposit if they withdraw.

Your lawyer must review the contract carefully before you sign and explain the legal consequences. Once signed, you are legally committed to complete the purchase unless there are valid grounds for withdrawal specified in the contract.

Step 7: Arrange Property Finance and Funds Transfer

If you require a mortgage, you should have approval in principle before signing the arras contract. Spanish banks lend to non-residents, though loan-to-value ratios are typically lower (60-70%) than in the UK, and interest rates may be higher.

For cash purchases or to transfer the deposit and balance, you need to arrange international money transfers from the UK to your Spanish bank account. Use a reputable currency exchange specialist rather than high-street banks to secure better exchange rates and lower fees, as the amounts involved mean small percentage differences translate to significant sums.

Keep detailed records of all fund transfers. Spanish tax authorities may require evidence that purchase funds came from legitimate sources outside Spain.

Budget for currency fluctuations if there is a delay between signing the arras and completion. Some buyers use forward contracts to fix the exchange rate in advance.

Step 8: Complete the Deed of Sale (Escritura)

The final step is signing the escritura de compraventa (deed of sale) before a Spanish notary. This is the legal completion of your purchase. Unlike UK property transactions where exchange and completion are separate, the escritura signing is a single event where ownership transfers immediately.

The notary is a public official who verifies the identity of all parties, confirms the legal capacity of all parties to buy and sell, reads the complete deed aloud (or confirms all parties have read it), collects the purchase price and ensures the transaction complies with Spanish law. The notary is impartial and does not represent either party.

You must bring valid passport or national ID, NIE certificate, proof of funds (banker's draft or confirmed bank transfer) and your lawyer (recommended but not legally required).

The seller must bring the original previous escritura, proof of identity, proof of IBI and community fee payment and habitation license if not previously provided.

The notary will retain the original signed escritura and provide certified copies to both parties. Your lawyer will use this certified copy to register the property in your name at the Land Registry.

Step 9: Pay Transfer Tax and Register the Property

Within 30 days of signing the escritura, you must pay the transfer tax (ITP) or VAT (IVA for new builds) to the Andalusian tax authorities. Your lawyer or gestor will prepare and submit the tax return (Modelo 600 for ITP or Modelo 620 for new builds) and arrange payment.

After tax payment, your lawyer submits the escritura and tax receipt to the Land Registry to register you as the new legal owner. Registration typically takes four to six weeks. Once complete, the Land Registry will issue a new nota simple in your name.

You should also pay the municipal plusvalía tax if applicable. This local tax on the increase in land value is sometimes paid by the seller (as negotiated in the contract), but buyers should verify payment has been made.
