His field of activity is to serve private clients in areas such as estate and tax consequences, relocation, trusts and other estate planning measures. Mr Lagonico practices also entertainment law and has been working for 22 years in Swiss, international and European laws.

Mr Lagonico’s preferred domain of service is to assist individuals and families, with a local or international ambit (various nationalities and/or residences, assets located in different countries) who wish to plan their estate and assess tax implications.

He assists his clients in their projects to acquire or relinquish a nationality. He regularly provides legal advice pertaining to the acquisition of real estate, in Switzerland or abroad, thanks to a well-established network of legal, tax and accounting practitioners. He advises international families and art collectors.

Mr Lagonico advises also authors, composers, interpreters, directors, producers, and other persons involved in the field of scenic arts (music, dance, film), providing as such, in the field of entertainment law, a complementary addition to the art law practice developed by Bonnard Lawson.

Before joining Bonnard Lawson, Mr Lagonico worked during three years in the United States, for two major American law firms, in their international departments, where he practiced in particular banking law. He taught a one semester class of international law at Georgetown University.
