Property Due Diligence in Marbella: What Your Lawyer Should Check

Property Due Diligence in Marbella: What Your Lawyer Should Check

Finding a property you love in Marbella is not the same thing as confirming that it is safe to buy.

Before a buyer becomes fully committed, an independent lawyer should investigate the legal position of the property and identify issues that may affect ownership, use, financing, future resale or the transaction itself.

This process is generally referred to as legal due diligence.

For a straightforward apartment, the review may be relatively simple.

For a large villa that has been extended, renovated several times or owned for decades, the investigation can become considerably more complex.

The higher the value of the property, the less sense it makes to rely on assumptions.

What Is Property Due Diligence?

Property due diligence is the process of verifying that what the buyer believes they are purchasing corresponds with the legal and documentary reality.

This can include confirming:

• who owns the property;

• whether the seller has the right to sell it;

• mortgages or charges;

• Land Registry information;

• community debts;

• municipal property tax;

• planning and building documentation;

• property surfaces;

• licences;

• contractual obligations.

The exact scope depends on the property.

There is no single identical checklist for every Marbella purchase.

Why Due Diligence Matters in Marbella

Marbella contains an unusually varied property stock.

Buyers may encounter:

• recently completed apartments;

• 1980s villas;

• extensively renovated houses;

• properties with multiple extensions;

• frontline beach homes;

• golf developments;

• large private estates.

A house may look entirely finished and established while still containing discrepancies between:

• the physical property;

• Land Registry;

• Cadastre;

• planning documentation.

Those differences need to be understood before purchase.

Start With the Land Registry

One of the first legal checks is normally the Registro de la Propiedad — Land Registry.

The Junta de Andalucía specifically recommends checking the Land Registry before formalising a residential purchase.

A registry search can help confirm:

• description of the property;

• registered owner;

• mortgages;

• easements;

• embargoes;

• other registered charges or restrictions.

What Is a Nota Simple?

A Nota Simple Informativa is one of the most commonly used Land Registry documents during a property transaction.

According to Spain’s Colegio de Registradores, it provides information including:

• identification of the registered property;

• identity of the registered owner or owners;

• nature and extent of registered rights;

• mortgages;

• usufructs;

• limitations and restrictions.

A Nota Simple is informational rather than a formal registry certification, but it is a fundamental starting point for legal review.

Confirm That the Seller Is the Registered Owner

This sounds obvious, but it should never be assumed.

Your lawyer should confirm that the person or entity selling the property corresponds with the registered ownership.

This can become particularly important where ownership involves:

• several family members;

• inheritance;

• companies;

• divorces;

• powers of attorney;

• usufruct arrangements.

The structure must be clear before the transaction proceeds.

Check Mortgages and Charges

The Land Registry should reveal registered charges affecting the property.

These may include:

• mortgages;

• embargoes;

• easements;

• restrictions.

The Junta de Andalucía specifically recommends using registry information to determine whether charges exist that could restrict the buyer’s rights of use or ownership.

If there is an existing mortgage, the purchase can still proceed, but the mechanism for cancelling or dealing with it should be clearly established.

A Mortgage on the Property Is Not Automatically a Problem

Many resale properties have mortgages.

What matters is that the buyer understands:

• outstanding registered charge;

• how it will be repaid;

• how cancellation will be documented;

• whether sufficient purchase funds are retained where necessary.

Your lawyer coordinates this as part of completion.

Check for Embargoes

An embargo can indicate that a registered claim or enforcement measure affects the property.

This does not necessarily mean the property cannot be purchased.

But it needs to be resolved correctly.

A buyer should never simply assume that every charge will disappear automatically after the sale.

Check Easements

An easement — servidumbre — may provide another party with rights affecting the property.

Examples can involve:

• access;

• utilities;

• roads;

• neighbouring land.

For a large villa or plot, easements can be particularly relevant.

The legal existence of a right of way may affect privacy and usability even if it appears insignificant during a viewing.

Land Registry vs Cadastre

The Land Registry and the Spanish Cadastre serve different purposes.

Buyers often encounter both.

Broadly:

Land Registry

Focuses on legal ownership and registered rights.

Cadastre

Contains physical and fiscal information about real estate.

A buyer should not assume the two records necessarily correspond perfectly.

Discrepancies in:

• surface;

• building footprint;

• plot shape;

• additions

may need further investigation.

Does the Registered Property Match What You Are Viewing?

This is one of the most important questions for villa buyers.

Imagine a listing advertises:

• 550 m² built;

• six bedrooms;

• pool;

• guest house;

• basement.

The buyer should not assume that all of those elements are reflected correctly in legal and planning documentation.

Your advisers should determine what is:

• registered;

• cadastral;

• licensed;

• physically present.

Marbella Villas Require Particular Attention

Villas often evolve over time.

A property may have been:

• extended;

• renovated;

• reconfigured;

• enclosed;

• expanded underground.

Common alterations can include:

• covered terraces converted to interior rooms;

• new bedrooms;

• enlarged basements;

• guest houses;

• garages converted into accommodation;

• additional terraces.

Each change should be understood in the context of the property’s legal and planning documentation.

Check Building Licences

Where construction or significant alterations have taken place, appropriate licences can be relevant.

Your lawyer may need to establish:

• what was originally authorised;

• whether subsequent works were licensed;

• whether the completed property corresponds with approvals.

The exact documentation varies according to age and type of property.

This is one area where a lawyer may coordinate with an architect or other technical professional.

Occupancy Documentation

Depending on the property, relevant occupation or use documentation should also be reviewed.

For newly constructed homes, the Junta de Andalucía identifies licences or administrative acts permitting use or occupation among the documentation that should be supplied to buyers.

Older properties can involve different documentation histories, which is why the review needs to be property-specific.

Do Not Assume “It Has Been There for 20 Years” Means It Is Regular

This is an important misconception.

The age of an extension does not, by itself, tell the buyer everything about its planning or registration position.

Different legal concepts can apply depending on:

• age;

• planning history;

• location;

• nature of the works.

If a discrepancy exists, the buyer's lawyer should explain what it means specifically for that property rather than relying on general statements.

Community of Owners

If the property forms part of a comunidad de propietarios, your lawyer should review the community position.

This applies to most:

• apartments;

• penthouses;

• townhouses;

• many gated villa developments.

Important information may include:

• current community fees;

• whether fees are paid;

• community statutes;

• planned major works;

• extraordinary assessments.

Community Debts Matter

The Junta de Andalucía recommends checking that the seller is up to date with community fees before purchasing.

Spanish Horizontal Property Law also requires the seller, at the public deed stage, to declare whether community charges are current and normally provide a certificate confirming the debt position, unless the buyer expressly waives that requirement.

This is not a formality buyers should ignore.

Why the Community Certificate Matters

Under current Horizontal Property Law, the acquired property itself can remain legally liable for certain unpaid community charges relating to the current year and the previous three calendar years.

That makes verification of community debt especially important.

A buyer should avoid casually waiving the relevant certificate without understanding the consequences.

Review Community Minutes

For apartments and high-service developments, reviewing recent community meeting minutes can reveal information that does not appear in property marketing.

Potential issues include:

• façade repairs;

• lift replacement;

• pool works;

• legal disputes;

• security changes;

• water problems;

• large future expenses.

An apartment that appears attractively priced can become less attractive if a major extraordinary assessment is approaching.

Check Community Rules

Community statutes or internal regulations may also matter.

They can affect areas such as:

• renovations;

• exterior modifications;

• use of communal facilities;

• noise;

• pets;

• property use.

For investment buyers, rules affecting rental activity can be particularly important.

Check IBI

IBI — Impuesto sobre Bienes Inmuebles is the annual municipal property tax.

The Junta de Andalucía advises buyers to confirm that the seller is up to date with IBI payments before purchase.

The most recent receipt is also useful because it tells the buyer what recurring municipal tax cost to expect.

Other Municipal Charges

Depending on the municipality and property, other local charges may also exist.

These can include waste-related charges.

Although usually small relative to the purchase price, buyers should understand the property's ongoing obligations.

Check the Property’s Contractual Situation

Your lawyer should verify whether anything affects the seller’s ability to deliver the property as agreed.

For example:

• existing tenant;

• long-term lease;

• short-term occupancy;

• possession issue.

A property advertised as vacant should be capable of being delivered as agreed.

Is the Property Being Sold Furnished?

If furniture is part of the transaction, it should be clearly documented.

This becomes especially relevant for Marbella luxury properties where the interior may contain substantial-value furnishings.

A written inventory may identify:

• furniture;

• appliances;

• outdoor furniture;

• gym equipment;

• lighting.

Artwork and personal decorative objects should not be assumed to be included unless agreed.

Energy Certificate

The applicable energy-performance documentation should also be checked.

For new developments, Andalucía's current housing legislation also requires developers to provide certain building and user documentation, including the Building Book and, in qualifying new or comprehensively rehabilitated housing, a user manual.

For resale buyers, the relevant documentation depends on the individual property.

New Build Due Diligence Is Different

Buying from a developer requires a different set of checks.

The buyer’s lawyer may review:

• developer identity;

• land ownership;

• building licence;

• project documentation;

• advance-payment protection;

• specifications;

• completion terms;

• occupation documentation.

If construction is still underway, the Junta de Andalucía states that the purchase documentation should specify matters such as the amount advanced, the entity and policy guaranteeing those funds, and the designated account.

Developer Brochure vs Contract

Marketing material should never be the only source of information.

The legal contract and technical specification determine what the developer is formally agreeing to deliver.

Buyers should distinguish between:

• illustrative renders;

• brochure descriptions;

• contractual specification.

If an element is important, confirm that it is included contractually.

Check Parking and Storage Separately

Many Marbella apartments include:

• underground parking;

• storage room.

Your lawyer should confirm their legal position.

They may be:

• separate registered properties;

• annexes to the apartment;

• usage rights.

Do not assume simply because they are shown during the viewing that their legal treatment is obvious.

Villa Boundaries

For substantial plots, boundary questions deserve careful attention.

The physical wall or hedge may not always be sufficient proof of the legal boundary.

If there is uncertainty, technical review may be necessary.

This can be particularly important for:

• large estates;

• older villas;

• hillside plots.

Swimming Pools

Pools can also form part of the planning review.

For an older villa, the lawyer and technical adviser may need to determine whether the pool is appropriately reflected in the relevant documentation.

The fact that a pool appears on satellite imagery does not answer the legal question.

Renovated Villas: Ask What Was Actually Done

A property marketed as “completely renovated” may range from cosmetic refurbishment to substantial structural alteration.

Your advisers should understand whether the renovation involved:

• structural changes;

• extensions;

• changes of use;

• new technical systems.

From the buyer’s perspective, renovation quality and legal regularity are separate questions.

Both matter.

Lawyer vs Architect: Different Jobs

Legal due diligence does not replace technical due diligence.

Lawyer

Reviews matters such as:

• title;

• charges;

• contracts;

• planning documentation;

• community and tax documentation.

Architect / Technical Professional

Can assess:

• physical condition;

• structure;

• construction quality;

• roof;

• moisture;

• technical systems;

• measurements.

For expensive villas, using both can provide a much more complete understanding of the property.

Technical Inspection

A technical inspection can be particularly valuable for:

• older villas;

• renovated homes;

• properties with basements;

• hillside villas;

• homes with retaining walls;

• houses showing moisture.

Potential issues may include:

• waterproofing;

• drainage;

• structural movement;

• roof problems;

• pool systems;

• electrical installations.

Legal cleanliness does not mean physical perfection.

Should You Inspect a Newly Renovated Villa?

Yes, particularly at high values.

Beautiful finishes can conceal technical issues.

A renovation may look impressive while retaining:

• old plumbing;

• old electrics;

• inadequate waterproofing;

• ageing air-conditioning equipment.

A professional inspection gives the buyer a different perspective from an aesthetic viewing.

Due Diligence Before Reservation or After?

The answer depends on the transaction structure.

Often, buyers sign a short reservation agreement first so the property is temporarily removed from the market.

The important point is that the reservation document should clearly establish the buyer’s position while legal checks are performed.

Before paying a large contractual deposit, due diligence should normally have progressed sufficiently for the buyer and lawyer to understand the property's legal situation.

What If There Is a Problem?

Not every irregularity kills a transaction.

Some issues can be:

• corrected by seller;

• regularised where legally possible;

• reflected in the contract;

• accepted by the buyer after advice.

Others can materially affect whether the purchase should proceed.

The lawyer’s job is not simply to produce a list of documents.

It is to explain the consequences.

A Discrepancy Is Not Automatically a Disaster

Marbella has a large stock of older property.

Documentation differences can therefore arise.

The relevant questions are:

What exactly is different?

Can it be corrected?

Does it affect use?

Does it affect mortgage financing?

Could it affect resale?

Is there enforcement risk?

Does it justify renegotiating?

This requires property-specific advice rather than generic assumptions.

Does Due Diligence Guarantee That Nothing Will Ever Go Wrong?

No.

Due diligence reduces risk by investigating the information and documentation available.

It cannot guarantee every future event.

For example, it cannot guarantee:

• future market values;

• behaviour of neighbours;

• future community decisions;

• every possible construction defect.

Its purpose is to allow the buyer to make the decision with a much clearer understanding of the property.

Buyer Due Diligence Checklist

Before completing a Marbella purchase, the buyer should expect the relevant advisers to have addressed questions such as:

Ownership

Is the seller entitled to sell?

Land Registry

Does the property correspond with the registered description?

Charges

Are there mortgages, embargoes or other registered restrictions?

Planning

Do the existing buildings and important alterations have an understood legal position?

Community

Are fees current?

Are there significant community issues or anticipated works?

IBI

Is municipal property tax current?

Property Use

Can the property be delivered in the possession condition agreed?

Contract

Does the purchase agreement protect the buyer appropriately?

Technical Condition

Should an architect or surveyor inspect the property?

Extra Checks for Villas

For villas, add particular attention to:

• plot boundaries;

• pool;

• extensions;

• basements;

• guest accommodation;

• retaining walls;

• renovation history;

• drainage;

• technical systems.

Villa due diligence can be substantially more complex than apartment due diligence.

Extra Checks for Apartments

Apartment buyers should pay particular attention to:

• community debts;

• community minutes;

• extraordinary assessments;

• statutes;

• parking;

• storage;

• façade and lift works.

The apartment itself may be excellent while the building has substantial upcoming costs.

Extra Checks for New Builds

New-build buyers should focus on:

• developer;

• licences;

• guaranteed advance payments;

• completion terms;

• specifications;

• occupation documentation;

• snagging.

New does not mean risk-free.

It simply involves a different category of risks.

What Buyers Should Never Do

Assume the Agent Has Performed Legal Due Diligence

The buyer should have their own independent lawyer.

Assume the Notary Replaces the Lawyer

The notary is a neutral public official, not the buyer’s personal adviser.

Assume an Old Alteration Must Be Legal

Age alone does not answer the legal question.

Ignore Community Documents

An apartment purchase includes participation in the wider community.

Focus Only on the Purchase Price

A property with unresolved legal or technical issues can become expensive after completion.

Due Diligence on Luxury Property

At higher budgets, complexity often increases.

Luxury properties may contain:

• multiple plots;

• guest houses;

• extensive basements;

• gyms;

• spas;

• indoor pools;

• staff areas;

• complex renovations.

Each additional structure or modification increases the importance of verifying documentation.

A €10 million villa deserves deeper review than a quick registry check.

Due Diligence and Negotiation

Due diligence can also affect commercial negotiation.

If the review identifies:

• necessary legal work;

• technical defects;

• unanticipated community costs;

• major repairs,

the buyer can decide whether the agreed price still makes sense.

Depending on the contract and timing, the parties may renegotiate or establish conditions for resolution.

The Goal Is Not to Find Problems

Good due diligence is not about inventing reasons not to buy.

Its purpose is to answer a simpler question:

Do I fully understand what I am buying?

A property with known manageable issues can still be an excellent purchase.

An apparently perfect property with unknown issues is a much greater risk.
