Founded in 1982 and nowadays established in Geneva and Hong Kong, Gillioz Dorsaz & Associés is a business law firm providing advice and legal representation in the conduct of their business to individual and corporate clients, both Swiss and foreign.

Imbued with a strong team spirit, our firm provides all its clients with highest-quality services combining diverse areas of expertise, including corporate law, tax, contracts and transactions, banking & finance and employment law. 

Our firm’s tax team provides advice and assistance to corporate entities and individuals in matters relating to direct and indirect tax. In particular, we assist our clients in setting up tax structures discussed and defined with them, managing their tax liability and resolving tax-related disputes. In international matters, we regularly deal with double-taxation agreements and collaborate with high-quality foreign counterparts to settle issues of cross-border or foreign taxation. The relations of trust we have established with the tax authorities are a definite asset in the conduct of our activities, whether in taking preventive measures or resolving disputes.

In business law matters, we assist our clients in negotiating and closing commercial transactions such as sales or acquisitions, cooperation agreements and securing financing and guarantees. We also have wide experience in analysing existing structures and in advising on reorganizations and restructurings of companies and groups of companies. 

Our banking & finance team advises numerous Swiss and foreign banks and finance institutions as well as financial intermediaries, independent asset managers, fund managers, trustees and FinTech companies. We assist them in setting up and organizing their corporate structure and activities, in obtaining the relevant FINMA licenses as well as in their dealings with their clients and regulatory authorities.

The activity of our employment team covers all aspects of Swiss employment law (both private and public employment law), as well as related areas such as social insurances, pension, data protection and unfair competition. We represent clients – both employers and employees - before judicial and administrative authorities and also advise them in all stages of the employment relationship, including hiring phase, remuneration schemes, business transfers, international secondments or transfers of employees, individual or collective dismissals, separation agreements, drafting of employment contracts and of various company policies.

Our international orientation and extensive experience of close collaboration with counterparts abroad enables us to conduct or coordinate highly complex transactions and litigation within Switzerland and at international level. We enjoy a strong reputation for reliability, professionalism and integrity among our clients, our peers and judicial and administrative authorities.
