The firm leading growth in Spain
With a 92% increase in turnover in 2024, CCS Abogados tops Iberian Lawyer’s ranking of percentage growth in turnover, thanks to a hybrid model that combines complex long-term litigation with established traditional areas

According to Iberian Lawyer’s ranking of the 50 law firms with the highest turnover in Spain in 2024 (see our article on Iberian Lawyer No. 144), CCS Abogados has led the percentage growth for the year with a 92% increase in turnover, reaching 13.1 million euros. This milestone consolidates the firm as one of the most dynamic players in the Spanish legal sector, thanks to a strategy based on specialisation, technological innovation and financial independence.
However, this growth is not the result of a one-off situation. Behind it lies a hybrid business model that combines experience in traditional legal areas with a clear commitment to highly complex mass litigation. The firm has led macro-cases such as the truck cartel case—with more than 4,100 favorable rulings—and is now facing what may be the largest litigation in the European tourism sector: the claim against Booking for anti-competitive clauses, representing the 16,000 companies associated with CEHAT. Jaime Concheiro, who runs the firm alongside Carlos Seoane and Miguel Caamaño, shares in this exclusive interview the keys behind this model of sustainable growth, supported by the development of proprietary tools and a clear roadmap: to grow through specialisation, without compromising legal excellence or long-term commitment.
The 92% growth in turnover during 2024 has positioned CCS as the fastest-growing law firm in Spain. What have been the main drivers of this growth and how has such rapid expansion been managed internally?
There are two business models: one is the traditional part of the legal profession (M&A, tax, civil, public, etc.) and the other is medium- and long-term projects, made up of 40 lawyers, which is dedicated to the resolution of complex legal disputes. Over the last six years, we have established ourselves as the law firm that has handled the most cartel damage claims in Spain, both in terms of number and amount. The increase in turnover is due to several significant rulings that have generated a significant financial return on some of these projects, particularly the one relating to the truck cartel. These are projects that are undertaken on a contingency basis and, as they have a long development period without generating income, the necessary expenses during their execution are covered internally with the firm’s own funds and with resources generated by other areas.
Which areas would you highlight as having experienced the most growth?
Apart from the firm’s organic growth in its traditional areas, two new projects have been developed. On the one hand, the claim against Booking for anti-competitive contractual clauses imposed on Spanish hotels. The second macro-case is the recovery of amounts of hydrocarbon tax unduly charged between 2013 and 2018. The Spanish Confederation of Freight Transport (CETM) and the Spanish Confederation of Bus Transport (CONFEBUS) commissioned us to handle this case, and more than 2,000 companies engaged in freight and passenger transport have joined this process, in which CCS Abogados is processing administrative and judicial claims amounting to 72 million euros.
What is the biggest challenge you have faced in this process of transformation and consolidation?
