Property and contract law

Property and contract law lies at the origin of the firm and is our main area of specialisation. Since 1992 we have advised companies and individuals on the ordering, protection and defence of their property interests, with a body of knowledge built up over more than thirty years of professional practice.

This branch of the law governs a large part of the economic relations of individuals and companies. It essentially comprises the law of obligations and contracts and the legal regime governing ownership and the other rights in rem. A command of this discipline provides a cross-cutting legal foundation from which to approach with rigour many of the questions that affect a person's assets.

In Catalonia, that specialisation also calls for a precise knowledge of Catalan civil law and of how it interacts with the rest of the legal system. Our continuous practice in Barcelona and in the rest of Catalonia allows us to bring both perspectives together in the analysis of every transaction, legal relationship or dispute.

Preventive advice and asset strategy

In property and contract law, acting in advance is usually the best way of protecting the client's interests. An inadequate contractual clause, an insufficient guarantee, a failure to check the legal or Land Registry position of a property, or a contract structure that has not properly assessed its tax consequences may later give rise to complex and costly disputes. An essential part of our work is therefore preventive in nature. Before documenting or formalising a transaction, we analyse its economic purpose, the interests of the parties, the legal risks, the guarantees required and the consequences of each alternative.

We do not see contract work as the mere drafting of a document. A contract must reflect the reality of the transaction, make reasonable provision for its contingencies and lay down effective mechanisms to protect the client if circumstances change or the other party is in breach.

The cross-cutting nature of property and contract law also calls for its relationship with other disciplines to be assessed. Where the transaction requires it, we build into the analysis its commercial, corporate, real estate or tax implications, so as to provide a legal answer consistent with the interests at stake as a whole.

National and Catalan civil law

Catalonia has a civil law of its own with a considerable bearing on property matters. Ownership, possession, situations of co-ownership and limited rights in rem, as well as important areas of obligations and contracts, are specifically regulated in the “Código Civil de Cataluña”, the Catalan Civil Code. Determining the applicable law correctly is not a merely academic question; it may shape the structure of a transaction, the content and effects of a contract, the exercise of a right or the strategy to be followed in the event of a dispute.

Our specialisation in property and contract law, together with the experience built up in applying Catalan civil law, allows us to advise companies and individuals on transactions and disputes that call for a particularly precise knowledge of this legal framework. This dual perspective is of particular importance in areas such as the sale and transfer of assets, purchase options, pre-emption rights, ownership and co-ownership, rights in rem, guarantees and the legal relationships connected with real estate assets.

Contracts, ownership and rights in rem

In contractual matters, we advise throughout the whole cycle of the legal relationship, from the analysis and structuring of the transaction, the negotiation and drafting of the contract, through to its amendment, performance and interpretation and, where necessary, its termination or discharge.

Our practice covers, among others, contracts of sale and purchase, purchase option, exchange, lease, assignment of business premises, provision of services, estate agency, lease of a business as a going concern, works, loan, mandate, deposit and acknowledgement of debt, as well as the setting up and regulation of co-ownership arrangements and of other property relationships between individuals or companies.

In the field of ownership and rights in rem, we advise on the acquisition, transfer, protection and legal ordering of real estate, as well as on situations of co-ownership and the division of co-owned property, possession, rights of first refusal and pre-emption, usufruct, use and habitation, easements, the determination and marking of boundaries, mortgages and pledges, declarations of new building works and matters relating to the “Registro de la Propiedad”, the Land Registry.

From advice to litigation

The same specialisation that we apply at the preventive stage is the foundation of how we act when a dispute arises. Before going to court, we analyse the possibilities of negotiation, mediation, conciliation or settlement and assess whether there is a solution that protects the client's interests without the need to commence court proceedings.

Where litigation proves unavoidable, a thorough knowledge of the substantive law comes fully into its own. Actions for performance, termination, nullity or rescission of contract, claims for payment, the defence of ownership or of possession and, in general, disputes over property all require the client's legal position to be determined precisely first, so that the appropriate litigation strategy can then be built. It is here that property and contract law and litigation, the firm's two long-standing specialisations, come together.

Can a restructuring be imposed on those who vote against it? The cram-down of creditors and shareholders

One of the most significant features of the new restructuring regime introduced by Spain's “Ley 16/2022” and by Directive (EU) 2019/1023 is that, on certain conditions, a court-confirmed plan may affect creditors that have not supported it and even, in certain situations, entire classes of creditors or the shareholders themselves. This mechanism —“arrastre” in Spanish, cram-down or cross-class cram-down in English-language terminology— does not mean that a majority may freely impose any solution it wishes. It is conditioned by the correct formation of classes, by the valuation of the business, by the treatment of dissenting creditors and by the comparison with the insolvency alternative. An understanding of these elements is essential to grasping how decision-making power is structured in a restructuring and what legal limits there are on imposing sacrifices on those who vote against.

What a due diligence should really uncover before buying a company

Due diligence in the sale and purchase of a company should not be conceived as a mere accumulation of documents and findings, but as a decision-making instrument. Its function is to identify which risks may alter the price, shape the structure of the transaction or even make it inadvisable. The value of the exercise does not lie in detecting the greatest possible number of issues, but in distinguishing which of them are material to the transaction and in translating them into specific decisions on the structure of the sale and purchase, the conditions precedent, the representations and warranties, the indemnities and the price retentions. A truly useful due diligence is one that connects the technical analysis with the drafting of the contract.

Sale of the former home after a separation: when the reinvestment exemption in personal income tax is retained

The disposal of the family home after a separation, divorce or annulment raises a recurring problem under the “IRPF”, Spain's personal income tax: can the spouse who had to leave the home continue to benefit from the exemption for reinvestment in a principal residence laid down in article 38 of Law 35/2006 of 28 November on personal income tax —the LIRPF—, when he or she sells his or her share and acquires a new dwelling? The judgment of the Third Chamber of the “Tribunal Supremo”, Spain's Supreme Court, of 27 May 2026, Second Section, cassation appeal 6833/2024, confirms and consolidates the doctrine begun by STS 553/2023 of 5 May and answers in the affirmative: the spouse who leaves the home under a court decision may satisfy the occupation requirement for the exemption where the other spouse and the couple's children have continued to live there. The key lies in a systematic interpretation of the concept of principal residence in article 41 bis of the “Reglamento del IRPF” —Spain's personal income tax regulations, the RIRPF—, approved by Royal Decree 439/2007 of 30 March, and in treating the family home as the point of reference.

Breach does not always permit termination: fundamental breach, article 1124 CC and the consequences of termination of the contract

Article 1124 of the “Código Civil” —the Spanish Civil Code— enshrines the right to terminate reciprocal obligations in the event of breach, but not every breach justifies termination. A serious or fundamental breach is required, one that frustrates the purpose of the contract. The non-defaulting party may choose between demanding performance and terminating the contract, in both cases with the right to damages and interest. Termination produces significant financial consequences, such as the restitution of the performances rendered, interest, fruits, actual loss and loss of profit, which may interact with penalty clauses and with the retention of sums paid. Recent case law, including judgment 489/2026 of the “Tribunal Supremo”, Spain's Supreme Court —STS—, shows the practical importance of these questions in disputes over termination for breach and clauses retaining payments in contracts for works and contracts of sale.

Ownership, possession and the passage of time: recovery of ownership, acquisitive prescription and unfair delay after STS 386/2026

The tension between ownership and possession is one of the central axes of the civil law of property. The action for recovery of ownership allows the owner to recover the thing from a possessor without title, but the passage of time may consolidate the possessor's position through acquisitive prescription, the Spanish “usucapión”, and, in certain cases, the prolonged inactivity of the holder of the right may be assessed through the doctrine of unfair delay, the “retraso desleal”. Judgment 386/2026 of 11 March of the “Tribunal Supremo” —Spain's Supreme Court, hence STS—, concerning the Pazo de Meirás, offers an exceptional framework for studying these general questions of civil law: the action for recovery of ownership, extraordinary acquisitive prescription, possession as owner, the public domain, possible tacit removal from public use, unfair delay and the settlement of the possessory position, without any need to focus on the historical circumstances of the case.

Unjust enrichment in the civil law of property and obligations: requirements, subsidiarity and limitation of the action

The unjust enrichment action has become established as a cross-cutting instrument of the civil law of property and obligations, used to correct situations in which one person is enriched at the expense of another without any legal cause justifying it and without any specific action for restitution being available. Its make-up requires enrichment, correlative impoverishment, absence of cause and subsidiarity in relation to other avenues, together with its careful distinction from undue payment, civil liability and contractual actions. STS 271/2026 of 20 February makes a highly topical contribution by examining an unjust enrichment action and addressing when prior criminal proceedings may interrupt the limitation period for the subsequent civil action, requiring a substantial connection between the facts investigated in the criminal proceedings and those underpinning the civil claim.

The claim changes creditor, but does the obligation change? Assignment of claims, ancillary rights and the debtor's defences

The assignment of claims is a central institution of the law of obligations and of contractual practice. It allows a creditor to transfer his claim to a third party, with its security and ancillary rights, without the need to create a new obligation. The “Código Civil” —the Spanish Civil Code, CC—, from articles 1526 onwards, and the “Ley Hipotecaria”, Spain's Mortgage Act, in its provisions on the assignment of mortgage-secured claims, provide the basic framework for analysing what is transferred with the claim, what part is played by the debtor's consent and by notice to him, what effects payment to the assignor has, what defences the debtor may raise against the assignee and how set-off operates. STS 22/2026 of 14 January, a judgment of the “Tribunal Supremo”, Spain's Supreme Court, returns to an essential principle: assignment does not create a new obligation, the assignee acquires the same claim, with its identity and content, and the change of creditor is not equivalent to the birth of a different claim. That principle makes it possible to build a broad body of doctrine on the identity of the obligation, the debtor's position and the difference between assignment, subrogation and novation.

Chronicle of an executorship for the realisation of an estate: bequeathing what you do not own

There are wills that are carried out by signing a public deed of acceptance of the estate and dividing up what there is. And there are others that, in order to be carried out at all, first require the deceased's corporate structure to be dismantled and the assets he had left to third parties without owning them to be taken out of it. This is the second kind. The firm acted as universal executor for the realisation of the estate —the “albacea universal de realización de herencia”— and completed the task in little more than eleven months, well within the time limit the testator had set. But the work that made that result possible did not begin with the death of the deceased, but years earlier, on the day he was helped to draw up his will.
