Civil liability

We advise and defend companies, professionals and individuals in civil liability matters and in claims for damages arising from professional, medical or healthcare practice, from construction, from defective products or from road traffic accidents, as well as in the “responsabilidad patrimonial de las Administraciones públicas” —the liability of public authorities in damages—.

Civil liability is not a uniform regime. The nature of the damage, its origin, the relationship between the parties and the field in which it arises determine different rules, avenues of claim, evidentiary criteria and systems of assessment. To these are added specific bodies of rules of decisive importance in construction, products, road traffic or healthcare and administrative activity. The initial assessment makes it possible to define with the client the appropriate strategy for claiming, negotiating or defending their position before the courts.

Professional liability

Every professional service provided by lawyers, accountants, tax advisers, architects, engineers, IT professionals, psychologists, etc. gives rise to duties whose scope cannot be assessed in the abstract. To determine whether there is liability, it is necessary to know what the professional was instructed to do, what obligations they assumed, what conduct could reasonably be required of them in the specific circumstances and whether there is a causal link between the conduct in question and the loss for which compensation is sought.

In these matters, we analyse both the position of the party who considers that they have suffered damage and that of the professional against whom the claim is brought. The contractual documentation, the background to the relationship, the communications exchanged, the decisions taken while the service was being provided and the technical evidence available are usually decisive in reconstructing what happened and delimiting responsibilities. A particularly complex question is distinguishing between improper conduct and the actual occurrence of compensable damage. Not every breach causes the loss claimed. In certain cases, the causal analysis calls for an assessment of what would have happened had the professional acted otherwise.

Where there is professional liability insurance, we bring the terms of the policy, the definition of the insured risk and the insurer's position into the analysis from the outset, so that this dimension of the matter is not relegated to the background.

Medical and healthcare liability

The liability of healthcare professionals doctors, surgeons, nurses, dentists, etc. requires a combined analysis of the care provided, the information available when the clinical decisions were taken, the patient's progress and the possible connection between the conduct in question and the outcome that occurred.

An adverse outcome does not in itself entail liability. It is necessary to reconstruct the care provided, examine the medical records and assess on technical grounds whether the treatment complied with the requirements of the medical practice applicable to the case. In these proceedings, the quality of the medical expert evidence and its proper integration into the legal argument are essential. Our practice also covers disputes over the information given to the patient and informed consent, the rules on which impose specific duties of information and documentation in the care relationship.

In addition, the applicable regime and the avenue of claim may vary depending on whether the care was provided privately or within the public health system. Before bringing a claim it is therefore essential to identify correctly the parties involved, the basis of liability and the appropriate avenue.

Construction and building

Damage arising from construction is one of the most complex areas of civil liability because a single project may involve developers, contractors, designers, the technicians of the “dirección facultativa” —the supervising technical team— and other parties, each with different functions and responsibilities. The “Ley de Ordenación de la Edificación”, Spain's Building Act, lays down a specific liability regime for the parties involved in the building process.

A crack, a leak, a structural defect, deficient insulation, a waterproofing problem or defective workmanship may stem from different causes and affect each party involved differently. Before claiming or mounting a defence, it is necessary to determine on technical grounds the origin of the defect and, as a matter of law, to whom it may be attributed. We therefore examine with particular care designs, contracts, site documentation, records, certificates, technical reports and any other background material that makes it possible to reconstruct the building process. Coordination between lawyer and expert is usually decisive, both in identifying the causes of the damage and in assessing its remedy.

Liability arising from building work may, moreover, rest on different legal bases and be subject to different time limits depending on the nature of the damage and the relationship between the parties. Our involvement starts from determining precisely the applicable regime before defining the actions to be brought or the defence against them.

Liability for defective products

Damage caused by defective products is governed by a specific legal regime that requires analysis of the product, the alleged defect, the damage caused, the circumstances in which the product was put into circulation and the causal link between the defect and the loss. This regime, laid down in consumer legislation, gives particular weight to proof of the defect, of the damage and of the causal link.

These matters may require determining who has the legal status of producer, manufacturer or importer, reconstructing the distribution chain and examining the technical characteristics of the product, its design, manufacture, presentation, instructions and reasonably foreseeable use.

Technical evidence again plays a central role here. Establishing whether an accident is due to a defect in the product, to the way it was used, to subsequent tampering or to some other cause usually calls for specialist analysis and an evidential strategy defined from the earliest stages of the matter.

We act both in claiming damage caused by products and in defending companies against liability claims, analysing together the applicable legal regime, the technical evidence and the economic dimension of the dispute.

Road traffic accidents and assessment of damage

Road traffic accidents also have a specific regime of civil liability, insurance and assessment of personal injury. The rules on civil liability and insurance in the use of motor vehicles are frequently amended and the sums of compensation they set are updated periodically.

Our involvement is not confined to determining who must answer for the accident. Where there is personal injury, it is necessary to analyse the temporary injury, the permanent sequelae, the care needs, the financial and professional consequences and the other heads that may make up the compensation. The medical documentation and the expert evidence are, once again, decisive. Assessing bodily injury correctly requires linking the injury to the accident, following its progress and having available the material needed to quantify its consequences once the injury has stabilised.

We advise on dealings and negotiations with insurers and, where no appropriate solution can be reached, we conduct the claim before the courts. More than thirty years of litigation experience allow us to assess from the outset not only the amount claimed but also how each of the heads making it up will have to be proved.

Liability of public authorities in damages

The liability of public authorities in damages is governed by its own regime of public law. The legislation recognises the right to compensation for certain injury to property and rights resulting from the normal or abnormal operation of public services, provided that the statutory requirements are met.

These claims require the damage to be identified precisely, its existence and extent to be proved, the causal link with the administrative action to be established and a determination as to whether or not the injured party is under a legal duty to bear it. The presence of other causes, the intervention of third parties or the injured party's own conduct may make the causal analysis one of the central questions in the proceedings.

Our involvement covers the preparation and filing of the claim at the administrative stage, the analysis and production of the necessary technical and financial evidence and, where the relief sought is refused, its defence before the “jurisdicción contencioso-administrativa”, the administrative courts. Administrative law, the civil law of property and litigation come together in this field, three areas particularly connected with our practice. The liability of public authorities in damages requires an understanding of the legal regime governing administrative action, but also the precise determination and assessment of the financial loss that action has caused and the building up, from the outset, of the evidence needed to obtain redress for it.

How far may a professional limit their own liability? Exclusion clauses, fees and freedom of contract after Supreme Court Judgment 949/2026

Judgment 949/2026 of 18 June of the “Tribunal Supremo” —Spain's Supreme Court, hence STS— examines a professional services contract entered into by a law firm which capped the professional's maximum liability at the amount of the fees received. The Chamber declares the clause void, not because it amounted to standard terms used against a consumer, but because it is incompatible with the structural principles of the contract and with the compensatory function of contractual liability, even in the context of a negotiated contract between professionals. The Court questions that the provider itself should be able to determine its liability ceiling indirectly through its fees, that the cap should operate regardless of the seriousness of the breach and that it may end up depriving the duty to compensate of all content. Although the case concerns lawyers, the doctrine may be extended to auditors, tax advisers, engineers, consultants and other providers of professional services.

Artificial intelligence and volume legal case management: what can be automated and what a lawyer must continue to decide

Artificial intelligence can substantially improve the handling of large volumes of documents and case files, but its usefulness depends on distinguishing between automating tasks and delegating legal decisions. Classifying information, detecting issues or preparing drafts can bring efficiency; assessing the evidence, taking on risk or defining a strategy continues to require oversight and professional judgement.

Beyond the LOE time limits: architects' contractual liability and owners' associations' standing after Supreme Court Judgment 860/2026

Judgment 860/2026 of 4 June of the “Tribunal Supremo” —Spain's Supreme Court— deals with a case in which an owners' association brought together ten-year liability actions under the “Ley de Ordenación de la Edificación” —the LOE, Spain's building legislation— and contractual actions under article 1101 of the “Código Civil”, the Spanish Civil Code, against an architect and a technical architect. The LOE actions against the two professionals were barred by limitation, but the Supreme Court confirms that this does not necessarily extinguish the contractual route and recognises the association's standing to bring the actions which originally belonged to the developer cooperative. The decision qualifies the obstacle posed by article 1257 CC as regards successive purchasers and owners' associations and makes it possible to clarify the difference between the LOE guarantee periods, the limitation period under article 18 LOE and the limitation period for the contractual action.

Unfinished works, liability intact: the architect's liability before acceptance of the works following STS 643/2026

Judgment 643/2026 of 28 April of the “Tribunal Supremo” —Spain's Supreme Court— deals with a case concerning a single-family house whose construction was left unfinished and which was never formally accepted in accordance with article 6 of the “Ley de Ordenación de la Edificación”, the LOE, Spain's building legislation. Despite this, the architect had made errors in the design and in the professional supervision of the works and had signed a “certificado final de obra”, a final works certificate, which did not correspond to reality. The Supreme Court rejects the argument that the absence of completion and acceptance may serve the architect as a means of escaping liability, and stresses that the LOE governs the building process and the professional obligations arising in the course of it. The decision makes it possible to examine acceptance of the works, the final certificate, errors of design and supervision, the difference between LOE liability and contractual liability and the principle that no one may benefit from their own breach, with particular interest in the Catalan context.

Notarial liability in Catalonia: Civil Code, CCCat and limitation after STS 506/2026

Judgment 506/2026 of the “Tribunal Supremo”, Spain's Supreme Court, of 7 April, addresses head-on which limitation regime applies to a claim in contract against a notary in respect of a deed executed in Catalonia. The “Audiencia Provincial”, the provincial appeal court, had held that the ten-year period laid down for personal actions in the “Código Civil de Cataluña” —the Catalan Civil Code, or CCCat— was applicable, but the Supreme Court overturns that approach and concludes that the Spanish Civil Code must be applied. Its reasoning rests on the fact that notarial liability is bound up with the regulation of authentic instruments, a matter falling within the State's exclusive competence, and on the need for a uniform answer regardless of the notarial district in which the negligent act occurs.
