Chambers  & Partners, The Legal 500 and Best Lawyers classify Legse-Fides Abogados once again as a leading law firm in Spain (Insurance), in their prestigious 2023 Legal Directories.

LEGSE Abogados, founded in 1995 by Segundo Ruiz, Doctor of Laws, is a law firm recognized for its expertise in providing legal services to international companies. CHAMBERS & PARTNERS, The LEGAL 500 and Best Lawyers recommend LEGSE-FIDES in their prestigious  directories, published in 2018, 2019, 2020, 2021, 2022 and 2023 (Insurance). Our main areas of practice are Insurance, Corporate and Commercial Law, Labour Law, White Collar Crime, Anti-Money Laundering and Litigation.

We have ongoing contracts for legal Insurance  advice with 42 companies and we are the “Insurance Ombudsman” of 12 companies (CHUBB European Group, Intesa SanPaolo Life, iptiQ -Swiss Re-, ACUNSA, BESTINVER, CA LIFE, etc.).

In 2004, LEGSE Abogados founded FIDES Abogados, of which LEGSE owns 95%. This firm is the tax representative in Spain of 28 first rate insurance companies. It is remarkable that the joint invoicing of both firms in subjects related to Insurance Law places LEGSE-FIDES in one of the first positions in this sector of the Spanish legal market. For example, in 2023, we managed 262 new legal proceedings related to life insurance, personal accident and health insurance (leader in Spain in terms of the number of judicial insurance proceedings of this kind).

From a doctrinal point of view, we are the leading Spanish law firm in Insurance Law,  due to the books we publish and the high-level courses we conduct. For example, in January 2019 we published the second edition of our book “Law for Insurers in Spain and Portugal” (293 pages). We also publish a quarterly Spanish Legal Up-Date, well known in our market.

International capability

LEGSE-FIDES Abogados’ traditional geographic work area has been Spain. However we are aware that in an increasingly globalized world a law firm should offer an international service. For this reason, LEGSE-FIDES Abogados offers services for insurance companies in principal countries, from an economical point of view, around the world. This is an international source of information, ideas and organisational systems, which allows us to improve the quality of the legal services we provide to our clients.

Our working languages are Spanish, English, French and German.


The Madrid Bar Association has resolved to honour the firm LEGSE FIDES with the Good Practice Seal in Equal Treatment between men and women in law practice. The award ceremony was held in the Royal Spanish Academy and it concluded with speeches delivered by the Spanish Ministry of Equality and the President of the Madrid Bar Association.
