Property completion in Spain is the final stage of a legal process that should have begun well before the buyer signs the public deed of sale before a Spanish Notary. Between reserving a property and completion, legal due diligence may reveal issues that were not apparent when the buyer first decided to proceed with the purchase.
Problems affecting ownership, registered charges, planning status, extensions, cadastral information, community debts or the seller’s ability to complete may all need to be identified and resolved before the purchase can safely proceed.
For foreign buyers, this period is particularly important. Paying a deposit or signing a private agreement does not make subsequent legal due diligence unnecessary. On the contrary: the period before property completion in Spain is when the buyer’s lawyer should ensure that the legal and documentary position of the property corresponds with what the buyer has agreed to purchase.
Key Takeaways
- Property completion in Spain should take place only after appropriate legal due diligence has been completed.
- The seller’s ownership and legal capacity to sell must be verified.
- Mortgages, embargoes, easements and other registered charges should be identified and dealt with before completion.
- The physical property may not correspond with its description in the Land Registry or Cadastre.
- Extensions, covered porches, garages, swimming pools and other alterations may require additional legal and planning investigation.
- Community debts, extraordinary assessments and local property tax liabilities should be checked.
- Problems discovered before completion do not always require the purchase to be abandoned: many can be resolved if they are identified sufficiently early.
- The Spanish Notary performs an essential public function but does not replace independent legal due diligence carried out in the buyer’s interests.
1. From Reservation to Property Completion in Spain
Once a property has been reserved, the transaction normally moves into a period of legal verification and preparation for completion. The precise contractual position will depend on the documents already signed by the parties, including any reservation or deposit agreement.
A reservation agreement should therefore be understood before it is signed, particularly as regards the legal effect of the deposit, the agreed deadlines and the circumstances in which the transaction may or may not proceed. You can read my separate guide to reservation agreements when buying property in Spain for a detailed analysis of that stage of the transaction.
This article focuses on a different question: what can arise after the initial commitment has been made and before the public deed of sale is signed.
2. What Might Go Wrong Before Property Completion in Spain?
Completion normally takes place through the execution of a public deed of sale (escritura pública de compraventa) before a Spanish Notary.
Before reaching that stage, the buyer’s legal advisers should have investigated the legal position of the property and prepared the transaction for completion. The precise scope of that investigation depends on the type of property, its location, its history and the terms agreed between buyer and seller.
Legal due diligence is not simply a matter of obtaining a Land Registry extract. It requires the different sources of legal and administrative information concerning the property to be examined together and any inconsistencies or risks to be identified.
When correctly performed, legal due diligence may identify a number of issues that need to be addressed before the purchase can safely proceed to completion. These may include:
2. a) The Seller’s Title May Not Be as Straightforward as Expected
An up-to-date Land Registry search (nota simple) is one of the first documents that should be examined.
It identifies the registered owner or owners and provides information about registered rights and charges affecting the property. It may reveal, for example, that the person negotiating the transaction is not the sole owner, that the property belongs to several family members or that an inheritance has not yet been registered.
Where several owners are involved, all persons whose consent is legally required must participate in the transaction personally or through a validly authorised representative.
The seller’s legal capacity and authority to dispose of the property should therefore be established before property completion in Spain is arranged.
2.b) Mortgages, Embargoes and Other Registered Charges
A Land Registry search may also reveal mortgages, attachments (embargos), easements, prohibitions on disposal or other rights affecting the property.
The existence of a mortgage does not necessarily prevent the sale. Spanish properties are frequently sold while a mortgage remains registered, provided that appropriate arrangements are made for repayment of the outstanding debt and cancellation of the charge where the buyer is to acquire the property free from that mortgage.
An embargo or another restriction may present a different problem and should be analysed according to its nature and registration status.
The important point is that the buyer should know before completion exactly which registered rights affect the property and how any charge that should not remain after the purchase will be dealt with.
2.c) The Physical Property May Not Match the Land Registry
A particularly important issue arises when the property that the buyer has visited does not correspond with the description recorded in the Land Registry.
A house may have been extended. A terrace may have been enclosed. A swimming pool, garage, covered porch or guest accommodation may have been added without being incorporated into the registered description.
These discrepancies should not automatically be dismissed as administrative details. Their significance depends on the nature and age of the works, their planning status and the applicable regional and municipal legislation.
The buyer should establish what is legally documented and compare it with what physically exists before deciding whether to proceed.
2.d) The Land Registry and Cadastre May Not Match
The Spanish Land Registry (Registro de la Propiedad) and the Cadastre (Catastro Inmobiliario) are different institutions and perform different functions.
The Land Registry is concerned principally with ownership and real rights. The Cadastre is an administrative register containing physical, economic and other information relating to real estate.
Differences may therefore exist between the two regarding surface area, boundaries, buildings or other descriptive elements.
The fact that an extension or other construction appears in the Cadastre does not, by itself, establish that it has been properly registered or that it complies with planning legislation.
Depending on the discrepancy, technical documentation and cadastral, notarial or Land Registry procedures may be required.
2.e) Extensions, Garages or Covered Porches May Require Investigation
This issue is particularly common when buying villas and houses that have been altered over the years.
An extension may exist physically and even appear in cadastral information without having been properly incorporated into the registered description of the property. Separate questions may also arise concerning its planning status.
It is therefore necessary to distinguish between planning legality, cadastral information and Land Registry description. They are related issues, but they are not legally interchangeable.
The appropriate investigation may involve building licences, planning records, technical certificates, evidence concerning the age of the works and the legal possibilities for documenting or regularising the existing situation.
You can read my separate guide to buying a property in Spain with extensions, covered porches or garages for a more detailed analysis of these issues.
2.f) The Licence of First Occupation or Equivalent Documentation
Depending on the location, type and age of the property, documentation concerning first occupation, use or an equivalent administrative regime may need to be investigated.
This area requires particular care because planning and housing regulation in Spain involves substantial Autonomous Community competence. The terminology, legal requirements and consequences of missing documentation are therefore not necessarily identical throughout Spain.
A missing Licence of First Occupation should consequently not be analysed through a generic rule applicable to every Spanish property.
The relevant questions are what documentation was legally required for that particular property, whether it exists, whether subsequent legislation or administrative procedures affect the position and what practical or legal consequences arise for the proposed acquisition.
For a detailed explanation, see my separate article on the Licence of First Occupation when buying property in Spain.
2.g) Community Debts and Extraordinary Assessments
If the property forms part of a Community of Owners (Comunidad de Propietarios), the buyer should investigate the seller’s position within that community.
Spanish Horizontal Property legislation contains specific rules concerning the certification of community debts when a property is transferred. The public deed must contain the seller’s declaration concerning outstanding community charges and, as a general rule, the corresponding certificate must be produced unless the buyer expressly waives that requirement.
However, checking whether current fees have been paid is not always enough.
The buyer should also consider whether extraordinary assessments (derramas) have been approved and whether significant works or expenditure affecting the building are anticipated.
A property with modest monthly community fees may nevertheless be subject to a substantial extraordinary contribution.
2.h) Outstanding IBI and Municipal Liabilities
Local property tax (Impuesto sobre Bienes Inmuebles or IBI) should also be checked before completion.
Spanish local tax legislation provides, in the circumstances established by law, for real property to remain legally affected by outstanding IBI liabilities following a transfer.
The payment position should therefore be verified rather than assuming that any outstanding liability is merely a personal matter between the seller and the local authority.
Other municipal matters may also require investigation depending on the particular property and transaction.
2. i) Financing May Not Be Ready for Completion
Foreign buyers requiring mortgage finance should ensure that their contractual obligations and financing position are properly coordinated.
The fact that the seller or estate agent knows that the buyer requires a mortgage does not necessarily mean that the purchase is legally conditional upon mortgage approval.
If financing is essential, the contractual documentation should be examined to determine what happens if the expected finance is not obtained.
A buyer who has assumed an unconditional contractual obligation may otherwise face consequences if financing fails before completion.
2. j) The Completion Deadline May Become a Problem
Private purchase agreements commonly establish a deadline for execution of the public deed.
International transactions can require additional time for NIE applications, powers of attorney, mortgage documentation, international transfers, company documents, inheritance formalities or the resolution of defects affecting the seller’s title.
A contractual completion date should therefore be taken seriously.
If a problem makes completion on the agreed date impossible, the parties should address the contractual position rather than simply allowing the deadline to expire. Depending on the agreement, an extension or other contractual arrangement may need to be documented.
2.k) The Seller May Not Be Ready or Able to Complete
Not every problem before completion originates with the buyer or the property itself.
The seller may discover that another owner’s consent is required, may not have completed an inheritance, may be unable to cancel a charge in time or may fail to produce documentation that the contract requires before completion.
The seller may also simply become unwilling to proceed.
The buyer’s rights in these circumstances depend on the contractual framework already established between the parties and the nature of the seller’s failure to perform.
3. What Happens If Legal Due Diligence Reveals a Problem?
Discovering a problem does not necessarily mean that the transaction must be abandoned.
Many issues can be resolved before completion. Mortgages can often be cancelled, documentation may be obtained, discrepancies may be corrected and contractual mechanisms can sometimes be agreed to address outstanding matters.
The relevant legal questions are:
- What exactly is the problem?
- Can it be resolved before completion?
- Who is responsible for resolving it?
- How long will the solution take?
- Should completion be conditional upon its resolution?
- Does the issue affect the property’s value or intended use?
- What contractual protection does the buyer require?
- Is there any residual risk if the buyer proceeds?
This analysis is considerably more useful than simply describing a problem as either “legal” or “illegal”. The objective of legal due diligence is to determine its actual consequences for the proposed purchase.
4. Can the Buyer Withdraw If a Problem Is Discovered?
Not always. Whether a buyer is entitled to withdraw, recover a deposit or require the seller to remedy a particular problem depends on the contractual position and the nature of the issue discovered.
This is one reason why legal advice should ideally be obtained before a reservation or deposit agreement is signed. If full due diligence has not yet been completed, appropriate contractual protection may be necessary.
A buyer should not assume that discovering something undesirable automatically creates a right to terminate the transaction and recover all sums already paid.
Before communicating withdrawal or treating a contract as terminated, the contractual consequences should therefore be carefully analysed.
5. What Should Legal Due Diligence Cover Before Property Completion in Spain?
The scope of due diligence depends on the property, but the investigation will commonly include consideration of:
- the seller’s identity, ownership and capacity to sell;
- an up-to-date Land Registry search;
- mortgages, embargoes, easements and other registered rights;
- the cadastral description and reference;
- consistency between the physical property, Land Registry and Cadastre;
- planning and building documentation where relevant;
- extensions, garages, covered porches, swimming pools and other alterations;
- first occupation, occupancy or equivalent documentation where applicable;
- Community of Owners documentation and outstanding charges;
- approved or relevant extraordinary community assessments;
- IBI and relevant municipal liabilities;
- existing leases, occupants or other rights of possession where applicable;
- the arrangements for cancellation of registered charges;
- the allocation of contractual expenses and taxes;
- financing conditions where relevant; and
- the documents and conditions required for completion before the Notary.
The purpose is not merely to collect documents. The lawyer must determine whether the information contained in those documents is consistent with the physical and legal reality of the property and whether any issue identified affects the buyer’s decision or requires action before completion.
6. What Should Be Checked Again Immediately Before Completion?
Due diligence should not necessarily be regarded as a single exercise carried out several weeks before completion.
The Land Registry position should be checked sufficiently close to completion to ensure that no relevant change has occurred since the earlier investigation. A nota simple reflects the registration information available when it is issued; it does not guarantee that the position can never subsequently change.
The buyer’s lawyer should also ensure that the matters agreed during the due diligence process are reflected in the arrangements for completion.
This may include mortgage cancellation, production of community documentation, settlement or retention of relevant amounts, delivery of documents and compliance with other contractual conditions.
10. Does the Spanish Notary Carry Out the Buyer’s Due Diligence?
No. This is an important distinction for foreign buyers.
The Spanish Notary performs an essential public function in connection with the execution of the public deed and carries out the legal controls, checks and warnings required by Spanish law.
However, the Notary is not the buyer’s independent lawyer and does not replace legal due diligence conducted specifically in the buyer’s interests.
The buyer’s lawyer analyses the individual transaction from the buyer’s perspective, investigates potential problems, reviews the contractual position and advises whether identified issues should be resolved before completion, reflected contractually or accepted as part of an informed decision to proceed.
7. Frequently Asked Questions About Property Completion in Spain
What is property completion in Spain?
Property completion in Spain normally refers to the stage at which the purchase is completed through execution of the public deed of sale before a Spanish Notary, with the corresponding completion arrangements for payment and transfer.
Can problems arise after I have already reserved the property?
Yes. Legal due diligence may subsequently reveal problems concerning ownership, registered charges, planning matters, extensions, cadastral discrepancies, community liabilities or other aspects of the property. This is why reservation should not be confused with completion of the legal investigation.
Can I lose my deposit if I cannot complete?
Potentially. The consequences depend on the contractual documentation, the legal nature of the payment and the reason why completion does not take place. The position should be analysed under the particular agreement rather than assuming that every property deposit has the same legal consequences.
Can I complete if the seller still has a mortgage?
Potentially, yes. A property subject to a mortgage can be sold, but appropriate arrangements must be made concerning the outstanding debt and the registered charge, particularly where the buyer has agreed to acquire the property free from that mortgage.
What if an extension is not registered?
The circumstances should be investigated before completion. The legal significance will depend on matters including the nature and age of the extension, its planning position, the applicable regional and municipal legislation and the available technical and legal documentation.
Is a Land Registry search enough before buying?
No. An up-to-date Land Registry search is essential, but proper legal due diligence may also require cadastral, planning, community, municipal, contractual and other investigations depending on the property.
Does the Notary protect me if something is wrong with the property?
The Notary performs the functions and legal controls assigned by Spanish law, but does not act as the buyer’s independent legal adviser. Independent legal due diligence should be carried out in the buyer’s interests before completion.
Should I have a lawyer before property completion in Spain?
Obtaining independent legal advice sufficiently early in the transaction allows the buyer’s lawyer to investigate the property, review the contractual obligations and identify problems while there is still time to determine whether they should be resolved, negotiated or taken into account before completion.
8. Legal Advice Before Property Completion in Spain
Property completion in Spain should be the final step of a properly investigated and structured acquisition rather than simply an appointment to sign a deed before a Notary.
The period before completion allows the buyer’s lawyer to verify ownership, investigate registered charges, compare the Land Registry and cadastral information with the physical property, examine planning and community issues and ensure that problems identified during due diligence are properly addressed.
I advise foreign clients buying property in Spain and provide legal assistance in English and French throughout the acquisition process, including legal due diligence, contractual advice, preparation for completion and execution of the public deed.
An experienced property lawyer does more than identify irregularities. The essential task is to determine their legal significance, assess whether and how they can be resolved and ensure that the buyer does not assume unnecessary legal or financial risks merely because a deposit has already been paid or a completion date has been agreed.
Obtaining legal advice before the buyer becomes unconditionally committed can prevent unnecessary expense, contractual disputes, delays and avoidable problems at property completion in Spain.
