What due diligence should every buyer carry out before signing in Spain?

Buying property in Spain is a straightforward process when handled correctly, but, as it is the world over, it is also a significant financial commitment. Whether purchasing a holiday apartment, a family home or an investment property, carrying out the appropriate due diligence before signing is essential.

Most transactions proceed smoothly, particularly in established markets such as Marbella and the Costa del Sol. However, thorough preparation helps buyers understand exactly what they are purchasing, avoid unnecessary surprises and gain confidence throughout the process.

This is also where the value of working with an experienced agent becomes clear. A good agent does far more than introduce properties. They help buyers navigate the purchase process, coordinate professional advice and ensure that important details are not overlooked.

Confirming legal ownership

One of the first checks should always be verification of ownership.

Before proceeding, buyers should ensure that the seller is the legal owner of the property and has the right to sell it. This is confirmed through a Land Registry search, which provides details of ownership, boundaries and any registered charges or restrictions affecting the property.

This may sound obvious, but it forms the foundation of every transaction and should never be assumed.

Checking for debts and charges

A property can carry obligations that transfer with ownership if they are not identified beforehand.

Community fees, local taxes and certain charges relating to the property should be reviewed carefully. In apartment developments and urbanisations, it is important to establish whether there are any outstanding community payments or extraordinary contributions planned for the future.

Buyers should also understand the ongoing annual costs associated with ownership, including local property taxes and community fees.

Verifying planning and licences

Particularly on the Costa del Sol, planning compliance is an important part of due diligence.

Buyers should confirm that the property has been built in accordance with the relevant licences and planning permissions. For newer homes, this includes checking that all necessary documentation has been issued by the local authorities.

For new-build properties, buyers should review building licences, guarantees and completion documentation. For resale homes, any extensions, alterations or structural changes should also be verified.

The objective is simple: ensuring that the property being purchased matches the legal documentation attached to it.

Understanding what is included

Property transactions can occasionally create confusion regarding fixtures, fittings and included features.

Before signing, buyers should have absolute clarity regarding what forms part of the purchase. This includes furniture, appliances, parking spaces, storage rooms and any additional elements advertised alongside the property.

Having these details confirmed in writing avoids misunderstandings later in the process.

Reviewing contracts carefully

Reservation agreements, private purchase contracts and title deeds all carry legal implications.

While many contracts follow standard formats, every purchase is unique. Buyers should ensure that all timelines, payment schedules and conditions are fully understood before signing.

This is particularly important when purchasing off-plan properties, where construction schedules, stage payments and completion dates form part of the agreement.

An independent lawyer should always review documentation before commitments are made.

Understanding financing requirements

For buyers using mortgage finance, securing approval early is important.

Different lenders have different criteria, particularly for international buyers. Understanding borrowing capacity, deposit requirements and associated costs helps prevent delays later in the process.

Even cash buyers benefit from understanding the full acquisition costs in advance, including taxes, legal fees, notary fees and registration costs.

Looking beyond the property itself

Due diligence extends beyond legal documentation.

Buyers should also consider how the property fits their long-term plans. Accessibility, surrounding infrastructure, future development plans, schools, healthcare and transport connections can all influence enjoyment and future value.

A property may be attractive today, but understanding how the surrounding area is evolving provides additional confidence in the purchase decision.

Why the right agent matters

This is where the right agent becomes particularly valuable.

An experienced agent is not simply there to open doors and negotiate a price. They provide context. They understand local planning considerations, market conditions, pricing trends and the nuances of different neighbourhoods.

Perhaps most importantly, they help buyers ask the right questions. Many international buyers purchase property in an unfamiliar legal and administrative environment. Having someone who understands the process, coordinates with lawyers and developers and identifies potential issues before they become problems can make a significant difference.

A good agent acts as a guide throughout the transaction, helping buyers move forward with transparency rather than uncertainty.

Confidence comes from preparation

The vast majority of property purchases on the Costa del Sol complete without difficulty. The reason is simple – buyers who take professional advice and conduct the appropriate checks put themselves in the strongest possible position.

Due diligence is not about expecting problems. It is about understanding exactly what you are buying and ensuring that every decision is based on accurate information.

For buyers, that knowledge creates confidence. For sellers, it helps transactions proceed efficiently. And for everyone involved, it contributes to a smoother experience from first viewing through to completion.
