Purchase of unpaid mortgage loans in the judicial phase in Spain
Comprehensive legal management: from procedural due diligence to taking possession of the property
Purchasing an unpaid mortgage allows an investor to replace the creditor and assume the rights associated with the debt and its guarantee, but it does not entail directly purchasing the mortgaged property.
The assignee assumes the creditor’s legal position under the terms established in the assignment, but does not automatically acquire ownership of the property. The eventual acquisition of the property will depend on the outcome of the foreclosure proceedings, a judicial auction, an adjudication, or an agreement with the debtor.
At Pellicer & Heredia, we advise national and international investors on the analysis and acquisition of defaulted or foreclosed mortgages, reviewing the debt, the guarantee, any encumbrances, the foreclosure process, and the costs necessary to recover the investment.

Do you need legal advice before investing in non-performing mortgage loans in Spain?
Before setting a price or signing the transfer agreement, it’s essential to understand the true value of the debt, the status of the foreclosure, any encumbrances on the property, and the costs required to recover your investment. Our team analyzes the transaction and helps you identify the legal, procedural, and financial risks before you make any commitments.
Key facts before purchasing a mortgage loan
The decision should not be based solely on the discount applied to the nominal debt. A meaningful assessment combines the legal position acquired, the available documentation, the net value of the asset, the procedural status and the expected time until recovery, adjudication or an agreement with the debtor.
Subject matter of the purchase
The credit and the transferred ancillary rights, not immediate ownership of the property
Formalisation
Assignment agreement and, for the transfer of the mortgage title, a public deed and registration in the Land Registry
Key legislation
Article 149 of the Mortgage Act and Articles 1526 to 1529 of the Civil Code
Proceedings
Existence, validity and specific stage of the mortgage enforcement proceedings or other related proceedings
Security
Mortgage priority, secured liability, auction value, prior and subsequent charges
Debt
Outstanding principal, interest, fees, legal costs, partial payments and potential limits on recovery
Property
Market value, physical condition, use, occupants, leases, community fees, taxes and encumbrances
Possible outcome
Debt recovery, refinancing, transfer in lieu of payment, agreed sale, auction sale or court adjudication
Time horizon
There is no standard timeframe; it depends on the case file, any procedural issues and the court’s workload
Key risk
That the recoverable amount and the net value of the asset are lower than expected
What do you acquire when purchasing a mortgage loan?
The transaction transfers a right to payment secured by a real guarantee. Under the Civil Code, the assignment includes, unless otherwise agreed or subject to any applicable specific provision, the ancillary rights attached to the credit, including the mortgage.
Article 149 of the Mortgage Act establishes that the assignee is subrogated to the rights of the assignor and that the assignment cannot place the debtor under any greater obligation than that already imposed by the original agreement.
The right to payment
The buyer becomes the holder of the credit to the extent defined in the assignment agreement. The actual outstanding amount, enforceable items, payments made, maturity date, limitation periods and documentation evidencing the debt must all be verified.
The mortgage security
The mortgage strengthens the prospects of recovery by making the property liable for fulfilment of the obligation. Its effectiveness depends on its Land Registry ranking, the registered mortgage liability, the agreed auction value and any charges or restrictions that may reduce the value available to the new creditor.
The creditor’s procedural position
Where judicial proceedings are already under way, the assignment may require proof of procedural succession and the submission of the documentation needed to continue pursuing recovery of the debt. The case file should be reviewed before the purchase to confirm that the claim brought, jurisdiction, enforceable title, notifications and steps already taken are compatible with the investor’s strategy.
What is not acquired automatically
The purchaser of the credit does not, by that fact alone, become the owner, landlord or possessor of the property. Nor can the purchaser assume that the mortgage will allow the full debt to be recovered. Acquisition of the property requires a court adjudication, sale and purchase, transfer in lieu of payment or another valid title, followed by the relevant Land Registry formalities and, where applicable, the effective transfer of possession.
How to purchase a mortgage loan in judicial proceedings step by step
The process should be structured before the assignment agreement is signed. The following sequence helps identify the legal, financial and operational risks that can turn an apparent opportunity into an investment that is difficult to recover.
Step 1: Define the investment objective
The priority is defined as recovering the debt, negotiating an exit with the debtor, acquiring the property at auction or building a portfolio of credits. The strategy determines the maximum price, the documentation required and the acceptable recovery period.
Step 2: Identify the assignor and the scope of the assignment
It is necessary to verify who is assigning the credit, their capacity to do so and which assets, guarantees, interest, costs, claims and documents are included or excluded. It must also be assessed whether the transaction is subject to regulatory requirements due to the nature of the loan, the borrower or the purchaser’s activities.
Step 3: Audit the agreement and the outstanding debt balance
The loan deed, amendments, repayment schedule, defaults, settlements, communications and payments are reviewed. The analysis must identify clauses that may be void, restricted or disputed, as their non-application may reduce the recoverable amount.
Step 4: Examine the Land Registry and the property
The Land Registry extract and registry certificate make it possible to verify ownership, the mortgage ranking and any charges. The legal assessment is completed by reviewing the market value, physical condition, occupants, tenancies, outstanding community fees, taxes and the foreseeable costs of maintenance or refurbishment.
Step 5: Review the entire court case file
Where enforcement proceedings have already begun, the claim, the order authorising enforcement, the payment demand, any opposition, procedural incidents, the certificate of charges, the auction notice and any appeal or suspension must be reviewed. Knowing the case number alone is not sufficient.
Step 6: Model different scenarios and set the maximum price
The purchase price must take into account the recoverable amount, the ranking of the security, any potential write-off, the duration of the proceedings, taxes, professional fees, non-recoverable legal costs, occupancy and the financial cost of the capital throughout the entire process.
Step 7: Negotiate contractual protections
The agreement must regulate the existence and validity of the credit, the delivery of documentation, the assignor’s representations, balance adjustments, payments received during closing, procedural cooperation, contingencies and the circumstances giving rise to termination or indemnification.
Step 8: Formalise and register the assignment
The transfer of the mortgage title is documented in a public deed and submitted to the Land Registry. The necessary notifications and proof of the new creditor’s title before the court or other parties are also coordinated.
Step 9: Implement the post-closing strategy
After closing, enforcement proceedings may continue, negotiations may begin, a transfer in lieu of payment may be proposed, an orderly sale of the property may be considered or the investor may participate in the auction. Each decision must be compared with the recovery alternative and the cost of prolonging the proceedings.
Legal due diligence of the mortgage loan
The legal review must reconstruct the transaction from the signing of the loan agreement through to the proposed assignment. Its purpose is not merely to confirm that a mortgage exists, but to determine what can be claimed, against whom, with what priority and through which procedure.
Loan and mortgage security documentation
- Mortgage loan deed, amendments, extensions, subrogations and subsequent agreements.
- Updated Land Registry extract and certificate of ownership and charges.
- Initial valuation, registered auction value and available technical documentation.
- History of instalments, payments, defaults, settlements, interest and fees.
- Payment demands, notices of acceleration and prior negotiations.
- Guarantees, sureties, insurance policies, additional security and any co-debtors.
Validity and enforceability of the debt
It must be verified whether the loan was accelerated in accordance with the agreement and the applicable legislation, whether the calculation of the debt is transparent and whether any clauses may be declared unfair or not properly incorporated into the agreement. In consumer loans, the review requires enhanced caution because a contractual issue may affect both the amount recoverable and the viability of the enforcement proceedings.
Ranking and sufficiency of the mortgage security
A first-ranking mortgage generally provides a stronger position, but it does not eliminate other risks. Tax charges, community fees, certain occupants’ rights, planning restrictions and enforcement costs can significantly reduce the net value. Prior charges remain in place and must be assessed as part of the overall economic cost of the transaction.
Potential right of redemption of a disputed claim
Article 1535 of the Civil Code regulates, subject to certain requirements, the debtor’s right to extinguish an assigned litigious credit by reimbursing the assignee for the price paid, the costs and the corresponding interest. Its application should not be presumed: it requires an analysis of when the credit became litigious, what proceedings are under way, how the assignment was carried out and whether any exception applies. This issue requires a specific legal assessment before completing the purchase.
Requirements for the purchaser and loan servicing
Certain transactions involving property loans granted to consumers may be subject to registration, conduct or servicing obligations arising from Law 5/2019 and its implementing regulations. The structure must be reviewed by reference to the type of property, the purpose of the loan, the borrower’s status and the activities the purchaser will carry out after the assignment. Not all investors or loan portfolios are treated in the same way.
Analysis of mortgage enforcement proceedings
Once the credit is subject to court proceedings, the case file becomes an essential part of the asset. The return on the investment may depend more on a defective notification, pending opposition or a suspension than on the nominal amount stated in the commercial documentation.
Enforceable title and legal standing
The court must have an enforceable title suitable for the proceedings, and the new creditor must be able to prove the transfer. The chain of title is particularly important where the credit has passed through several entities or forms part of a portfolio. Any break in the documentary chain may lead to delays, opposition or difficulties with registration.
Payment demand and notifications
The validity of service and other procedural communications must be reviewed in detail. Incorrect notification to the debtor, a third-party possessor, subsequent rights holders or occupants may require steps to be repeated or lead to procedural incidents that alter the expected timetable.
Opposition, unfair terms and stays of proceedings
Mortgage enforcement proceedings allow only the statutory grounds of opposition, including certain issues relating to the extinguishment of the security, errors in the amount claimed or unfair terms. Insolvency, criminal, declaratory or vulnerability-related proceedings may also affect the progress of the case. The strategy must take each potential issue into account before the price is set.
Certificate of charges and Land Registry status
The certificate provides information on ownership and the charges affecting the auction. The analysis must distinguish prior charges, which normally remain in place, from subsequent charges that may be cancelled depending on the outcome of the proceedings. The date, ranking and financial scope of each Land Registry entry are decisive.
Court auction and possible adjudication of the property
The auction is a mechanism for enforcing the security, not a guarantee that the property will be acquired. The outcome depends on the bids submitted, the nature of the property, whether it is the debtor’s principal residence, the amount of the debt and the rules in force for approving the auction sale or requesting adjudication.
Auction value and market value
The auction value stated in the deed does not necessarily correspond to the property’s current market price. It may be outdated, higher or lower than the actual value and may not reflect the condition of the property. The investment decision requires an independent valuation and an estimate of the net value after charges, taxes, possession-related costs and repairs.
Statutory thresholds for approval
The Spanish Civil Procedure Act uses percentages of the auction value to regulate different scenarios for approving the auction sale and protecting the debtor, with specific rules for a principal residence. The 70% threshold is an important reference, but it does not operate as a single rule or guarantee that the creditor can acquire the property in every case. The provisions in force must be applied to the specific proceedings.
Charges, surplus proceeds and cancellation of Land Registry entries
The proceeds obtained are applied to the credit in accordance with legal and Land Registry priority. If there is a surplus, it is distributed to the relevant entitled parties. Following adjudication, the property must be registered and the appropriate charges cancelled, without confusing them with obligations or encumbrances that may remain in force.
Possession, occupants and eviction
Registration of the adjudication does not always result in the immediate transfer of physical possession. It is necessary to establish who occupies the property, on what legal basis, whether a tenancy exists, whether minors or vulnerable persons are involved and what procedural action may be required. The time and cost involved in recovering possession must be incorporated into the financial model.
How to calculate the actual return on the transaction
The discount applied to the outstanding balance provides only a partial view. A prudent estimate uses several scenarios and deducts all costs up to the likely date of recovery or sale of the property.
Assignment price
Capital paid to the assignor and any closing adjustments
Legally recoverable debt
Principal, interest and amounts that can actually be claimed
Net property value
Market value less charges, taxes, community fees, refurbishment costs and selling expenses
Time
Financial cost of capital during negotiations, enforcement proceedings, the auction and possession
Legal and procedural costs
Notary, Land Registry, court representative, banking lawyer, expert witnesses, deposits and incidental proceedings
Risk of legal challenge
Possible debt reduction, repetition of actions, or suspension.
Possession status
Cost and timeframe required to obtain possession and place the asset into use or put it up for sale
Taxation
Tax treatment of the assignment, recovery, adjudication and subsequent transfer, depending on the structure
Exit strategy
Recovery, settlement, transfer in lieu of payment, sale of the credit, adjudication or sale of the property
Key risks when investing in non-performing mortgage loans
The investment may offer attractive returns, but it involves significant legal, property-related and timing risks. Identifying them does not eliminate uncertainty, although it helps establish a coherent price and avoid transactions whose success depends on a single optimistic assumption.
Purchasing a debt whose outstanding balance is not properly evidenced
The debt calculations may include disputed items, unapplied payments or interest that the court may not allow.
Overvaluing the mortgage security
The auction value, historical valuation and market price are different figures. Charges and occupancy may reduce the value available.
Assuming the proceedings will continue without complications
Opposition, defective notifications, missing documentation or insolvency proceedings may delay or alter the enforcement process.
Failing to assess the borrower’s consumer status
Consumer protection legislation and the review of unfair terms may limit the claim and require a more detailed examination of the agreement.
Ignoring the right of redemption of a disputed claim
Where the relevant requirements are met, Article 1535 of the Civil Code may alter the expected financial outcome.
Failing to account for the cost of obtaining possession
Registration of the adjudication may be followed by additional procedures to recover physical possession of the property.
Signing an assignment agreement with insufficient protections
The agreement must allocate the risks relating to documentation, the outstanding balance, interim payments, legal disputes, defects in title and procedural cooperation.
Failing to review regulatory requirements
The professional acquisition or servicing of certain property loans may be subject to specific requirements.
Possible outcomes after purchasing the credit
Not every transaction should end with adjudication of the property. The best exit will be the one that maximises risk-adjusted recovery and reduces the time for which the capital remains tied up.
Voluntary repayment or refinancing agreement
The new creditor may negotiate a payment schedule, a conditional debt reduction, additional security or early repayment. The agreement must be documented without prejudicing the mortgage priority or the existing procedural position.
Agreed sale of the property
In some cases, an orderly sale by the owner may achieve a higher price than a forced sale. The transaction requires coordination of the debt cancellation, allocation of the proceeds, existing charges and delivery of possession.
Transfer in lieu of payment
The debtor may transfer the property to the creditor in full or partial settlement of the debt. Before accepting, the property’s value, charges, tax implications, occupancy status and the exact extent of the debtor’s release must be verified.
Continuation of enforcement proceedings and auction
Where no negotiated solution is reached, the assignee may continue the proceedings provided that its position is properly evidenced. The decision must take into account the possibility of a third-party bid, adjudication, opposition and the subsequent recovery of possession.
Resale of the credit
Once the documentation has been properly organised or the enforcement proceedings have advanced, the investor may transfer the credit to another purchaser. The liquidity of this exit depends on the quality of the case file, the value of the security and the transparency of the available information.
Documents an investor should request
The exact list varies depending on the transaction, but the review of the mortgage loan should not begin without a sufficient set of documents to reconstruct the debt, the security and the proceedings.
- Mortgage loan deed and all its amendments.
- Complete documentation of the chain of title to the credit.
- Certificate of outstanding balance and historical breakdown of payments and defaults.
- Notices of acceleration, payment demands and settlement proposals.
- Updated Land Registry extract and certificate.
- Valuations, technical reports, photographs and available planning documentation.
- Enforcement claim, order authorising enforcement and the complete court case file.
- Statements of opposition, appeals, procedural incidents and pending decisions.
- Information on occupants, tenancies and proceedings for the recovery of possession.
- Receipts for community fees, property tax (IBI) and other expenses associated with the property.
- Proposed assignment agreement and schedules setting out the seller’s warranties.
- Tax and corporate information required to structure the acquisition.

Frequently Asked Questions
What does purchasing a mortgage loan involve?
It is the acquisition of the right to recover a loan secured by a mortgage. The purchaser, known as the assignee, replaces the previous creditor to the extent provided for in the assignment and receives the ancillary rights attached to the credit. The transaction does not automatically transfer ownership of the property. To acquire it, there must be a court adjudication, a transfer in lieu of payment, a sale and purchase or another valid legal title.
Does purchasing a non-performing mortgage loan mean buying the property?
No. The immediate subject of the transaction is the credit and its security, not the property. The mortgage allows enforcement to be pursued against the property if the legal requirements are met, but the investor will only become the owner when there is a valid title of acquisition and the corresponding registration has been completed. It is also possible for a third party to win the auction, allowing the new creditor to recover funds without acquiring the property.
What rights does the purchaser of the credit acquire?
The assignee acquires the right to payment on the terms transferred and, as a general rule, the ancillary rights attached to the credit, such as the mortgage, guarantees or associated preferential rights. The assignee may also assume the creditor’s position in the enforcement proceedings if the assignment is properly evidenced. However, the assignee cannot claim more from the debtor than is permitted by the original agreement, the law and the applicable court decisions.
How is the assignment of a mortgage loan formalised in Spain?
The agreement must precisely define the credit being transferred, the price, the outstanding balance, the guarantees and the documentation. Article 149 of the Mortgage Act provides that the transfer of the mortgage title must be formalised in a public deed and registered with the Land Registry. Where court proceedings are under way, the succession of the new creditor must also be evidenced before the court.
Is it mandatory to notify the debtor of the assignment?
Notification serves an essential practical purpose: it prevents the debtor from validly paying the previous creditor because they were unaware of the assignment and helps establish an orderly recovery process. The method and timing should be determined according to the agreement, the status of the loan and any existing proceedings. Failure to notify may create risks and liabilities, so it should be coordinated with the public deed and the procedural strategy.
Can a foreign investor purchase a mortgage loan?
Yes, but the acquisition must be structured in accordance with Spanish law, and the investor must have the necessary tax identification and powers of attorney. The corporate structure, anti-money laundering requirements, taxation and any regulatory obligations associated with the servicing of real estate loans must also be reviewed. A notarised power of attorney may allow the investor to formalise and manage part of the process without having to travel repeatedly to Spain.
What should the due diligence review cover before purchasing?
The review should cover the deed and any amendments, the outstanding amount due, payments, contractual clauses, the chain of title, the mortgage ranking, charges, the value of the property, occupancy and the complete court file. It is also advisable to model taxes, professional fees, possession costs, the expected duration and any potential reductions in the debt. The review should conclude with financial scenarios and conditions to be included in the assignment agreement.
What is the right of redemption for a disputed credit?
Article 1535 of the Spanish Civil Code allows the debtor, where the relevant requirements are met, to extinguish a disputed credit that has been sold by reimbursing the assignee for the price paid, the costs incurred and interest on the price. Its application is technical and the right does not arise merely because of a default or the existence of legal proceedings. The disputed nature of the credit, the procedural stage, the assignee’s claim and the statutory exceptions must all be analysed.
What happens if the loan contains unfair terms?
An unfair term may be unenforceable and may affect acceleration of the loan, interest, fees or the amount claimed. In consumer loans, the court may review these terms within the enforcement proceedings. The investor should quantify the debt without relying on legally questionable amounts and assess whether the issue requires the balance to be recalculated, the strategy to be modified or the purchase to be abandoned.
Why do I need a lawyer before signing the assignment agreement?
The commercial documentation usually summarises the outstanding balance and the property, but it does not replace a review of the agreement, the Land Registry and the court file. A lawyer can identify limits on recovery, procedural defects, charges, occupancy risks and the purchaser’s obligations. They can also translate those findings into contractual warranties, conditions precedent and a maximum purchase price consistent with the likely recovery.
Can I continue mortgage enforcement proceedings initiated by the bank?
In principle, the assignment may allow the new creditor to continue the proceedings, but the succession must be evidenced and the validity of the court file reviewed. The chain of documentation, the registration of the mortgage, notifications, objections and pending court decisions may affect the progress of the proceedings. Before purchasing, it is necessary to confirm the appropriate procedural action and whether there are any grounds for suspension or dismissal.
Does 70% of the auction value guarantee adjudication?
No. The 70% threshold is a reference used by the Spanish Civil Procedure Act in certain cases concerning approval of the auction and protection of the debtor’s main residence, but the outcome depends on the bids, the debt, the condition of the property and the rules applicable to the case. It should not be used as an automatic formula for valuing the credit or for assuming that the creditor will acquire the property.
What happens to charges that predate the mortgage?
Earlier-ranking charges generally retain their priority and may remain in force after the auction. The purchaser must take their financial impact into account when valuing the property. Later charges may be subject to cancellation in accordance with the proceedings and the allocation of the sale proceeds, but each Land Registry entry must be analysed individually. A basic Land Registry extract may be insufficient if the proceedings are already at an advanced stage.
What happens if the property is occupied?
Adjudication does not guarantee the immediate recovery of possession. It is necessary to determine whether the occupants are owners, tenants or third parties without legal title, and whether there are circumstances of vulnerability or parallel proceedings. Recovering possession may require additional court action. The timeframe, professional fees, condition of the property and risk of damage must be factored into the maximum purchase price.
Is it better to negotiate with the debtor or proceed to auction?
¿Es mejor negociar con el deudor o llegar a subasta?
It depends on the net value of each alternative. A payment agreement, an agreed sale or a transfer in lieu of payment may reduce the time and costs involved. An auction may be appropriate where there is no cooperation or the security sufficiently covers the exposure, but it adds uncertainty regarding bidders, adjudication and possession. The decision should be based on a comparison of the net return and risk associated with each exit strategy.
What return can a non-performing mortgage loan offer?
The return cannot be determined solely from the difference between the nominal debt and the purchase price. It must be calculated on the amount that can realistically be recovered, after deducting charges, taxes, expenses, the duration of the process, litigation, occupancy risks and financing costs. A transaction acquired at a substantial discount may still result in losses if the security is insufficient or enforcement is not viable. For this reason, it is advisable to work with conservative, probable and favourable scenarios.
How long does it take to recover the investment?
There is no single timeframe. A negotiated solution may be reached within weeks or months, whereas enforcement proceedings involving objections, appeals, insolvency proceedings, an auction or possession issues may continue for several years. The estimate should be based on the actual status of the court proceedings, the issues already raised and the proposed strategy. It is prudent to calculate the expected return using a conservative timeframe.
What taxes and costs can the transaction give rise to?
The tax treatment depends on who acquires the credit, how the assignment is structured, the type of credit, any eventual recovery, the adjudication and the subsequent sale of the property. There may also be notarial, Land Registry, court, expert, community and possession costs. A generic percentage should not be applied: the tax analysis must be carried out before setting the price and should distinguish between each stage of the investment.
