Buying a Property with Encumbrances: Legal Guide to Protect Your Investment in Barcelona

18 de February de 2026

By: Gemma Pérez Boyé

 

Purchasing a property represents for most people one of the most significant investments of their lives. However, this process can become a source of legal problems if, after signing, “hidden encumbrances” that were not disclosed by the seller are discovered. Specialized advice in real estate law is essential to prevent these situations and adequately protect your assets.

At BB Abogados, we have recently received numerous inquiries about property purchases with encumbrances and claims for hidden defects. This guide explains what these encumbrances are, what protection Spanish and Catalan law offers, and how to act to ensure a safe purchase in Barcelona.

What are property encumbrances?

Encumbrances are rights, obligations, or limitations that affect the use, enjoyment, or value of a property. To be legally enforceable against third parties, they must be registered in the Property Registry. Understanding these encumbrances before purchase constitutes an essential element of any legal advice in real estate transactions.

Most common types of encumbrances

Mortgages: Guarantee the repayment of a loan granted to the previous owner. If the seller does not cancel the mortgage before the sale, the debt remains attached to the property. The new owner could face foreclosure proceedings if the installments are not paid, regardless of having paid the full purchase price.

Liens: Constitute precautionary or enforcement measures derived from the owner’s debts with the Tax Authority, Social Security, the city council, or private creditors. These liens are secured by the property and may result in the forced auction of the property to satisfy outstanding debts.

Easements: Represent limitations on the use of the property for the benefit of another property or public service. Rights of way allow third parties to cross the property to access their own. Light and view easements limit construction in height or proximity. Aqueduct or power line easements allow the passage of installations through the estate.

Usufructs: Grant a person the right to use and enjoy the property without being the legal owner. This figure is common in inheritances where children inherit bare ownership while one parent retains lifelong usufruct. The buyer of bare ownership will not be able to use the dwelling until the usufruct expires.

Rights of first refusal and redemption: Grant certain persons or entities preference to acquire the property in case of sale. Tenants of commercial premises frequently enjoy this right, as do co-owners in shared ownership situations.

The seller’s duty of transparency: Spanish legal framework

Spanish legislation imposes on the seller a duty of transparency and good faith in all real estate transactions. This duty implies that they must deliver the property free of undeclared encumbrances and provide truthful and complete information about its legal status.

The Civil Code establishes in articles 1474 and following the seller’s obligation to guarantee “legal and peaceful possession” of the thing sold. This guarantee extends to the absence of charges or encumbrances that have not been expressly agreed upon or that the buyer did not know about at the time of acquisition.

The Housing Rights Act and consumer protection regulations reinforce this obligation, requiring that all relevant information about the physical and legal characteristics of the property be provided to the buyer before signing. Failure to comply with these disclosure duties may result in additional liabilities for the seller.

Legal protection in Spain: warranty against hidden encumbrances

If, after signing the deed of sale, an encumbrance is discovered that was not mentioned nor known by the buyer, the Spanish Civil Code protects the purchaser through the figure of “warranty against hidden encumbrances,” regulated in articles 1475 and following.

Requirements to invoke the warranty

To be entitled to this legal protection, three cumulative requirements must be met:

First: That the encumbrance was not apparent nor expressly mentioned in the deed of sale. Manifest encumbrances or those about which the seller adequately informed do not generate the right to warranty.

Second: That it is of such a nature that, had the buyer known about it, they reasonably would not have acquired the property or would have paid a lower price. This requirement is assessed objectively according to the magnitude of the encumbrance and its impact on the value or use of the property.

Third: That the encumbrance was registered in the Property Registry at the time of purchase, even if the buyer did not know about it. Unregistered encumbrances are generally not enforceable against a third party acting in good faith who registers their acquisition.

Remedies available to the buyer

If these requirements are met, the buyer has a period of one year from the execution of the public deed to exercise their rights. This period is one of limitation, not prescription, so its expiration definitively extinguishes the action.

The buyer can choose between two main options:

Rescind the contract: Request the rescission of the sale, recovering the price paid plus the expenses of the transaction and the corresponding legal interest. The property must be returned to the seller in the state in which it is found.

Request compensation: Claim financial compensation for the damages suffered, while maintaining ownership of the property. This compensation must cover the lower value of the property due to the encumbrance, expenses incurred for its cancellation if possible, and any other proven damage.

The particularity in Catalonia: lack of conformity

Book Six of the Civil Code of Catalonia introduces a broader and more modern concept than traditional warranty: the “lack of conformity” of the delivered good. This regulation, applicable to all sales in Catalonia, offers more complete protection to the buyer.

According to article 621-30 of the Catalan Civil Code, goods must be free of third-party rights or claims that have not been expressly agreed upon in the contract. If there are undeclared charges or encumbrances, the good is considered not to conform to the contract, regardless of whether the seller knew of their existence or not.

Remedies for lack of conformity

Article 621-37 of the Civil Code of Catalonia establishes a more flexible system of remedies adapted to the specific circumstances of each case. The buyer can choose between:

Demand specific performance: Require the seller to cancel the encumbrance at their expense, restoring the property to the agreed legal situation. This option is especially useful when the encumbrance can be eliminated by paying a reasonable amount.

Reduce the price: Request a reduction proportional to the lower value that the property has due to the existence of the encumbrance. This reduction is calculated through expert assessment, comparing the value of the property free of encumbrances with its actual value affected by them.

Terminate the contract: If the breach is essential and frustrates the purpose of the purchase. Termination is appropriate when the encumbrance is of such magnitude that it makes the acquisition useless or very burdensome for the purposes reasonably pursued by the buyer.

Claim compensation: For all damages caused by the lack of conformity, which may be combined with any of the previous remedies. This additional compensation covers additional damages such as advisory expenses, lost opportunities, or proven loss of profit.

This Catalan regulation offers protection more focused on ensuring that the acquired good effectively corresponds to what was agreed upon, regardless of subjective considerations about the seller’s knowledge.

Practical recommendations for a safe purchase: due diligence

Prevention constitutes the best tool to avoid problems related to hidden encumbrances. Professional legal advice during the pre-purchase phase is essential to identify and resolve these risks.

Request an updated property registry note

The property registry note (nota simple) constitutes the fundamental document to know the real legal situation of any property. This document, which can be requested directly from the Property Registry or through its electronic headquarters, reflects the current ownership of the property, all registered encumbrances (mortgages, liens, easements), existing limitations on ownership, and the history of recent transfers.

It is essential to request an updated property registry note a few days before signing the public deed, not settling for old documents provided by the seller. Between the date of an old registry note and the signing, new liens, mortgages, or limitations may have been registered.

Thoroughly review contracts

Both the earnest money contract and the final deed of sale must include specific clauses that protect the buyer. It is essential that the seller expressly states that the property is being transferred free of charges and encumbrances, except those that are declared and expressly accepted.

The contract must establish that the seller is obliged to cancel any existing encumbrance before signing the public deed, except those that the buyer agrees to assume explicitly. It is advisable to agree on penalties or automatic termination of the contract if the seller does not cancel the committed encumbrances.

It is recommended to include a clause that allows the buyer to verify through a new registry note, immediately before signing before the notary, that no additional encumbrances have been registered since the earnest money contract.

Claims for hidden defects: additional buyer protection

In addition to legal encumbrances registered in the Registry, buyers may also face hidden defects of a physical or material nature in the property. These defects, which were not apparent at the time of purchase and which reduce the value or habitability of the property, are also protected by legislation.

The Civil Code regulates warranty for hidden defects in articles 1484 and following, establishing the seller’s liability for hidden defects that make the thing unsuitable for the use for which it is intended, or that diminish this use to such an extent that, had the buyer known about them, they would not have acquired it or would have paid less for it.

In Catalonia, these hidden defects are also integrated into the concept of lack of conformity, allowing the buyer to exercise the same remedies described above: specific performance (repair), price reduction, contract termination, or compensation.

The deadlines for claiming hidden defects are strict: the buyer must report them within a maximum period of six months from their discovery, and the legal action prescribes six months from the report to the seller (one year in the Catalan Civil Code).

Conclusion: the importance of prevention

Purchasing a property with hidden encumbrances or undeclared defects can turn an exciting investment into a legal and economic problem that is difficult to solve. Spanish and Catalan legislation offer protection mechanisms for the buyer, but these legal remedies are always more expensive, slow, and conflictive than adequate prevention.

Carrying out complete due diligence before signing, professional review of all documentation, and inclusion of appropriate contractual clauses constitute the best guarantee for a safe purchase. Specialized legal advice is not a dispensable expense, but an essential investment that protects the buyer’s assets.

Frequently asked questions

Can I claim if I discover an encumbrance several years after the purchase?

Legal deadlines for claiming are strict. In the Spanish Civil Code, the period to exercise the action for warranty against hidden encumbrances is one year from the execution of the deed. In Catalonia, the general period is three years from the delivery of the good. After these periods expire, the right to claim through this route is lost.

What happens if I bought the property with a mortgage and discover subsequent encumbrances?

If the encumbrances are subsequent to the registration of your acquisition, they generally do not affect you due to the principle of registry priority. However, if they are prior and were not detected, you could claim against the seller within the legal deadlines. It is essential to have requested an updated registry note before the purchase.

Is the notary responsible if they do not detect the encumbrances?

The notary has the duty to verify ownership and registered encumbrances in the Registry by consulting the property folio. If there is a registered encumbrance and the notary does not warn about it, they could incur professional liability. However, the notary is not responsible for unregistered encumbrances or for material defects not visible in the documentation.

Can I cancel the earnest money contract if I discover encumbrances before the deed?

If the earnest money contract includes a clause for transfer free of encumbrances and undeclared encumbrances are discovered, the seller’s breach can generally be invoked to terminate the contract and recover the earnest money delivered. The precise wording of the earnest money contract is essential to protect this possibility.
