About us

Nomos Consulting Group is a law firm made up of a select group of professionals with vast and consolidated international experience. What defines us, both individually and collectively, is ethical and theoretical rigor, argumentative solidity and the most advanced domain of legal concepts. In a word, what defines us is, above all, the unequivocal commitment to excellence.

Gathered around a comfortable physical structure and the best technological resources, we can put into practice two fascinating projects that we would like to present to you.

The first one we call Nomos Legal Consulting. Acting in coordination, we want to demonstrate how essential theoretical refinement is for solving the most complex practical challenges. Nomos Legal Consulting is a legal consultancy center designed to offer to law firms the best and most well-founded answer to their intricate issues, be they in court or in arbitration proceedings.

The second project is called Nomos Institute. With it, we revitalize, now together, what we already do individually: the contribution to the theoretical and practical training of professionals who recognize the invaluable importance of continuous improvement. Nomos Institute is a training center designed to meet the highest technical-scientific standards.

Both in our consultancy center and in our training center, we work especially in the following areas: Constitutional Law, Criminal Law, Administrative Law, Political and Electoral Law, Procedural Law and Evidence Law, Digital Law and Artificial Intelligence. We also intervene in issues related to other areas and which, due to their complexity, require a qualified legal pronouncement in some of the areas in which we operate.

Consulting and Training

Consulting and Training

Nomos Legal Consulting

The so-called “concrete cases” are a challenge that we face with enthusiasm. We believe that intellectuals can – and should – renounce the “ivory tower” in which many take refuge, as we know that the theorist needs to submit their constructions not only to the formal-abstract rigors that guide thought, but also to the intricate demands of practical considerations.

Nomos Legal Consulting is what we call our consultancy center designed to offer to law firms the best and most well-founded solution to their legal issues. We put a sophisticated theoretical repertoire at the disposal of our consultants, who with our support can safely perform at the highest level.

We are particularly active in the preparation of legal opinions for highly complex issues to be judged by the highest Courts or in the most demanding arbitration procedures. We also offer advice on the drafting of legislative texts and formulate preventive strategies capable of preventing our clients from facing future legal challenges.

We work especially in the following fields: Constitutional Law, Criminal Law, Administrative Law, Political and Electoral Law, Procedural Law and Evidence Law, Digital Law and Artificial Intelligence, while also participating in the solution of issues in other areas whenever a qualified pronouncement is required under our expertise.

According to the interests of our clients, we can recommend law firms in the most diverse countries. These are the highest-level law firms with whom we enter into collaboration agreements that allow us to act together without, however, any corporate or hierarchical relationship between us. By executing such collaboration, we aim to have professionals of maximum excellence by our side and thus offer our clients the most complete legal support.


Nomos Institute

Training at the highest level is a requirement for excellence. In fact, without a broad and consistent intellectual repertoire the legal professional remains vulnerable, given over to theoretical helplessness. Having a deficient training is to have any greater pretense unfeasible. Let us remove this danger.

Nomos Institute is a qualified training center to give legal professionals the theoretical and practical training they need.

With a team formed by highly reputable professors, and also working in partnership with international institutions of maximum academic prestige, we meet the highest standards of technical-scientific demand.

We organize courses, lectures, seminars, congresses and other activities aimed at providing consistent and sophisticated answers to the important issues that challenge the legal theory and practice of our time. We take care of the improvement and training of all those who intervene in the legal culture of our societies, such as magistrates, public prosecutors, lawyers and university professors who, individually or together in another training institution, are committed to excellence in performing their duties and the invaluable importance of continuous improvement.

With our teaching experience, we develop training activities in all areas of law.
