Real estate

We advise investors, owners and operators in the sector on the acquisition, holding and transfer of property and real estate assets, as well as on the structuring of such transactions.

A property transaction does not end with the sale and purchase contract. Title to the asset and the encumbrances over it, its position at the Land Registry and under planning law, the existing licences, the intended use, the guarantees offered by the parties, the financing and the tax consequences may all be decisive in deciding whether the transaction should go ahead and, if so, how it should be structured.

We therefore become involved from the earliest stages of the transaction. We analyse the asset and the transaction as a whole, identify the legal risks and coordinate the relevant practice areas before the client takes on commitments that are difficult to change. Our specialisation in the civil law of property and obligations is the foundation of this practice, to which we add planning, commercial, corporate and tax analysis whenever the transaction requires it.

Planning and structuring the property transaction

A well-structured transaction begins before the “arras” —the earnest-money deposit agreement— or the sale and purchase contract is signed. We are involved from the initial stage in reviewing and negotiating letters of intent, preliminary agreements and conditions precedent. We define with the client the scope of the legal review and the documents the counterparty is to provide. Our aim is for the client to know the main risks before committing the investment, and for the preliminary documentation to protect their position properly while the analysis is under way.

This stage makes it possible to identify from the outset which issues have to be resolved before moving forward and which conditions will have to be met before the transaction can finally be formalised. Planning is especially important where what is being acquired is a development under way, an asset that is not yet finished, a property subject to specific licences or authorisations, or a project whose future operation depends on a particular planning or administrative use.

Legal, planning and tourism due diligence

Due diligence is one of the central stages of the advice we provide on property matters. In the legal review we analyse title to the property, its position at the Land Registry and the encumbrances, mortgages, attachments, easements and other rights that may limit or condition its acquisition or operation. We also examine the construction or development documentation and the relevant contracts linked to the asset. Where there are advance payments, or the property is bought while still under construction, we study the legal regime governing sums paid on account and the guarantees securing them.

Where one or more tenanted dwellings are being acquired in Barcelona, we pay particular attention to the extraordinary complexity of the legal framework governing housing and residential and commercial tenancies. In this field, State legislation coexists with a dense body of Catalan rules, which govern housing, the residential stock, stressed residential market areas and intervention in the rental market according to criteria of their own. On occasion, the outcome of this review may make the purchase inadvisable or justify a reduction in the price.

The planning analysis runs in parallel. We review the applicable planning instruments, the classification and zoning of the land, the compatibility of the intended use, the building and operating licences, the history of the municipal case file and any other authorisations that may be required. Where the asset is to be operated as tourist accommodation, we also check that it holds the relevant administrative authorisation and that the property as it physically exists and as it is marketed matches the units, uses and capacity actually authorised. This analysis is particularly relevant because a property may be correctly registered and yet have planning or administrative problems that substantially affect its value or the use the buyer intends to make of it.

Due diligence should not be confined to listing contingencies. Our task is to determine which of them are genuinely relevant to the transaction, what consequences they may have and how they should then be reflected in the price, the conditions precedent, the guarantees or the decision to invest itself.

Earnest-money deposits, guarantees and property contracts

Once the risks have been identified and the structure of the transaction defined, we negotiate and draft the contractual documentation. In earnest-money deposit contracts and other preparatory agreements we pay particular attention to the conditions precedent, the payment schedule, the consequences of breach, the grounds for termination and the mechanisms for refunding sums paid in advance. In sale and purchase contracts and deeds we seek to ensure that the allocation of risk reflects the findings of the due diligence.

Contractual work is even more complex in transactions involving off-plan property or developments still under construction. In these cases the characteristics of the property, the condition in which it will be handed over, the requirements and documents needed for completion, the construction and handover deadlines and the consequences of any departure from what was envisaged must all be regulated precisely. Where payments are made before handover or before the works are finished, we examine closely the guarantees protecting the buyer, such as bank guarantees, surety insurance or other instruments securing the return of the sums paid if the transaction is not carried through on the agreed terms.

The preliminary analysis and the contractual work are thus part of a single strategy. Every risk identified must have an appropriate legal answer before the transaction is finally formalised.

Tax treatment of property transactions

Tax can substantially shape the structure of a property transaction and must be analysed before the main decisions are taken.

We examine the tax consequences of acquiring, holding, disposing of and operating the asset, in particular the treatment of VAT and of the “impuesto sobre transmisiones patrimoniales y actos jurídicos documentados” (transfer tax and stamp duty), as well as the other tax obligations attached to the transaction. Where the investment calls for a company or a special-purpose vehicle, we coordinate the tax treatment of the transaction with its commercial and financial structuring.

Tax is therefore part of the design of the transaction from the outset. It should not be analysed only when the time comes to settle the taxes, because it may have a bearing on the contractual structure, the financing, the payment schedule and even on whether particular alternatives are advisable.

Licences for tourist-use dwellings in Catalonia after STC 64/2025

Catalan Decree-Law 3/2023 made the operation of tourist-use dwellings in 262 municipalities subject to prior planning permission, with licences valid for five years and renewable and a statutory ceiling of ten tourist-use dwellings for every one hundred inhabitants. STC 64/2025 of 13 March, a judgment of the Spanish Constitutional Court, dismissed the constitutional challenge in its entirety and held that these restrictions delimit the social function of property rather than amounting to an expropriatory deprivation. This new paradigm raises with particular force the question of whether there is a vested right to operate a dwelling as tourist accommodation, and requires the condominium regime, planning law and the right to property in Catalonia to be read together.

A prior notification allows the activity to begin, but it is not an administrative authorisation

The widespread use of the prior notification and of the “declaración responsable” —the declaration of compliance— as instruments replacing licences has transformed the way in which citizens and businesses deal with public authorities. That transformation has, however, also given rise to confusion as to the legal nature of these instruments and as to their review by the courts. The judgment of the Third Chamber of the “Tribunal Supremo”, Spain's Supreme Court, of 20 April 2026, Fifth Section, cassation appeal 2290/2023, makes it clear that a prior notification is not an administrative act open to challenge as though it were a licence. It is a declaration by the private party to which the law attributes authorising effect, enabling the activity to be started or the right to be exercised from the day of its filing, without prejudice to the public authority's subsequent powers of verification, inspection and response. If false statements, omissions or breaches come to light, it is the subsequent administrative act –of ineffectiveness, suspension, closure or penalty– that may be challenged. The doctrine has significant consequences for business openings, economic activities, property owners, local councils and affected third parties.

New urban developments and water availability: when a planning instrument can be annulled

Urban expansion is no longer measured solely in square metres of classified land, but also in cubic metres of legally available water. The judgment of the Third Chamber of the “Tribunal Supremo”, Spain's Supreme Court, of 15 April 2026, Fifth Section, cassation appeal 9014/2023, clearly establishes that the creation of new development areas requires the sufficiency and the legal availability of water resources to be verified, even where the municipality is losing population. The binding report of the river basin authority, the Spanish “organismo de cuenca”, cannot be omitted or deprived of content where the development will generate new demands for water, and failure to comply with it may lead to the annulment of the plan. The judgment also accepts that the annulment may be confined to particular sectors where the defect can be isolated without affecting the coherence of the rest of the plan. The doctrine is of direct interest to developers, landowners, local councils and practitioners involved in preparing or challenging planning instruments.

Can the tax authorities use a mortgage valuation to raise the tax value of a property?

The use by the tax authorities of the mortgage valuation incorporated into the deed in order to raise the tax value of a property has been the subject of intense debate in academic commentary and in the case law. The judgments of the Third Chamber of the “Tribunal Supremo”, Spain's Supreme Court, of 23 and 27 February 2026, in line with the Chamber's official case‑law report for the 2025–2026 two‑year period, confirm that, in cases where a “comprobación de valores” —a review of declared values— is available, the tax authorities may have recourse to the mortgage valuation figure where there is a material difference from the value declared, without any need to establish fraud or concealment beforehand. That valuation does not, however, become an irrebuttable presumption: the taxpayer may contest it by means of expert evidence and, where appropriate, through the “tasación pericial contradictoria”, the adversarial expert valuation provided for in the “Ley General Tributaria”, Spain's General Tax Act —the LGT—. This mechanism must be clearly distinguished from the cadastral reference value, which operates as a direct taxable base in the “Impuesto sobre Transmisiones Patrimoniales y Actos Jurídicos Documentados”, Spain's transfer tax and stamp duty, and in the “Impuesto sobre Sucesiones y Donaciones”, its inheritance and gift tax.

Dividing is not parcelling out the co-ownership: a judgment on the limits of condominium (“propiedad horizontal”) as a way of dividing jointly owned property

No one is obliged to remain in a co-ownership. That is the starting point of Article 552-10 of the “Código Civil de Cataluña”, the Catalan Civil Code, and the raison d'être of the action for division. From that follows something that seems obvious but is often disputed in practice, a division that leaves the co-owners sharing the resulting properties all over again does not fulfil the purpose of the action. The judgment obtained by this Barcelona law firm confirms this and declares the property physically and legally indivisible, over the opposition of the majority co-owner, who was seeking precisely that.
