He Graduated on Law at the Navarra University and in parallel he reached the Economic Bachelor degree. In 2022 Valentí was honored as Doctor Honoris Causa in recognition to his outstanding defenses of international and local clients in Andorran cases.

During 12 years he has been The General Secretary of the Andorra Parliament and was a Parliamentarist, «Conseller General», for 17 years 1995-2012.

Those were the years when the Principality of Andorra initiated the Constitution and started opening the Principality to more International Relations. It added associations to the centenarian relations of its Co-princes (France President and Bishop Seu Urgell-Vatican) and its friendly neighbours (Spain and Portugal).

Valentí co-led the legal framework of other countries by sitting as a Permanent Secretary in the Council of Europe in Strasbourg, at the Malta Mediterranean Association and at the LatinAmerica Summits held during those 12 years of his Secretariat.

In addition to his international legal expertise, since 2012 he actively participates at the andorran political environment by being the Secretary of International Affairs at the Liberal party (current opposition party of the 2012-2020 Government). During those years, he promoted the new keynesian economics to be ideally implemented in a country like Andorra. It is not by coincidence that the signature of a renewed Keneysian Manifest of the Liberal Parties around the world took place in Andorra in 2017.

Since 2012, Valentí holds his law firm in Andorra, where he advices international clients on fiscal and mercantile activities. He helps foreigners on their introduction and easy immersion to the Andorra benefits.

Amongst his international profile, may we underline that he has strong fiscal and legal knowledge on Spain, Russia, United Arab Emirates, France or Portugal.
