Avoiding Pitfalls: Common Legal Mistakes Foreign Buyers Make in Costa del Sol (2025 Guide)

Buying property in Costa del Sol is a dream for many, but without the right legal knowledge, that dream can quickly turn into a costly nightmare. Spain’s real estate laws are detailed and unique, especially for international buyers who may not be familiar with local property regulations. According to recent market research, over 35% of foreign buyers in Spain experience unexpected legal or tax complications after purchasing their property.

In this 2025 guide, we’ll explore the most common legal mistakes foreign investors make when buying property in Costa del Sol, and show you how to avoid them. Whether you’re purchasing a holiday home, relocating permanently, or investing for rental income, understanding Spain’s legal framework is essential to protecting your investment.

Understanding the Spanish Property Legal System

Spain’s legal system provides strong protections for property owners, but it functions differently from many other countries. Buyers should understand the roles of key parties: the notary, who certifies property deeds; the lawyer or solicitor, who conducts due diligence and ensures legal compliance; and the real estate agent, who connects buyers with legitimate listings.

It’s highly recommended to hire an independent bilingual solicitor who can interpret legal documents, liaise with local authorities, and ensure the property is free of any legal encumbrances before you sign.

Skipping Due Diligence on Property Titles

Failing to verify property ownership details can result in serious financial loss. Every buyer should check the Land Registry (Registro de la Propiedad) and request a Nota Simple, which confirms ownership and any debts or restrictions tied to the property.

Some foreign buyers have unknowingly purchased homes still under mortgage or affected by unpaid community fees. Conducting a full title search before purchase ensures peace of mind and protects you from future disputes.

Not Understanding the Legal Role of the Notary

Many buyers assume the Spanish notary functions like a solicitor. However, the notary’s role is limited to verifying and witnessing the transaction, not advising on its fairness or legality.

A notary ensures the sale complies with Spanish law but does not conduct due diligence. This is why you still need your own independent lawyer to review contracts, confirm ownership, and safeguard your rights throughout the purchase process.

Failing to Verify Building Permits and Property Licences

Before committing to a property, confirm it has the necessary building permits, planning permissions, and occupancy licence (Licencia de Primera Ocupación). Some properties in Costa del Sol were built without full approval or later modified without proper documentation.

Purchasing such properties can lead to fines, demolition orders, or refusal of utility connections. Always request confirmation from local authorities that the property is fully compliant with urban planning laws.

Ignoring Tax Obligations and Additional Fees

Many buyers overlook Spain’s property taxes, which include ITP (Property Transfer Tax) for resale homes, IVA (VAT) for new builds, and AJD (Stamp Duty).

There are also ongoing obligations such as IBI (municipal property tax), non-resident income tax, and community fees for shared developments. Understanding your full tax liability from the outset can prevent double taxation or unexpected penalties later.

Signing Contracts Without Legal Translation or Review

Never sign a purchase contract you don’t fully understand. All legal documents should be professionally translated into your language before signing. Review the deposit agreement (Contrato de Arras) carefully, it defines what happens if either party withdraws.

Ensure your solicitor checks for unfair clauses, such as penalties or conditions that heavily favour the seller. Having a bilingual legal expert can save you from costly errors and disputes.

Overlooking Inheritance and Residency Laws

Spain’s inheritance law includes forced heirship rules, meaning assets may not automatically go to your preferred beneficiaries. Property ownership also affects your residency and potential eligibility for Spain’s Golden Visa programme.

Couples buying jointly should understand how ownership structures impact inheritance tax and succession rights. Drafting a Spanish will is a crucial step to ensure your heirs are protected.

How to Avoid Legal Risks When Buying in Costa del Sol

A secure purchase begins with thorough preparation. Work with reputable professionals who understand both Spanish and international property law. Request a legal audit before completion, ensure the property has no outstanding debts, and verify all documents independently.

Choosing a trusted real estate agent is equally important. They should guide you through every step, coordinate with your solicitor, and provide transparent information about fees, taxes, and timelines.
