Reto Hunsperger specialises in litigation and arbitration. With this focus, he represents national and international companies and individuals before state courts and arbitral tribunals (under ICC Rules, Swiss Rules and CAS Rules), mainly in civil, enforcement and sport law matters. In addition, he serves as arbitrator.

A further focus of Reto Hunsperger lies on all sorts of domestic and international insolvency matters. He has in particular profound expert knowledge in the area of international insolvency law and he advises and assists i.a. foreign insolvency administrators in enforcing claims and adding domestic assets to the foreign insolvency estate. Likewise, he has broad know how in the Swiss insolvency law like for example in the representation of parties in all matters of debt enforcement, bankruptcy and restructuring related proceedings before Swiss authorities and courts.

Finally, Reto Hunsperger is member of the core team of the global CMS Commercial Practice Area Group. He advises his clients in all aspects of commercial law matters, in particular in the drafting of tailor-made sales and service agreements and of complex distribution arrangements as well as of general terms and conditions.

After a traineeship as attorney trainee with a major Zurich business law firm he was admitted to the bar in 2005. He then worked for three years as an associate of a middle-sized law firm in Zurich. Reto Hunsperger joined CMS as attorney in 2009 and is partner since 2015.

“In my view, the role of a good litigator is not only to vigorously defend the client’s interests in an ongoing litigation, but also – at first – to carefully analyse the client’s legal starting position and to discuss with him frankly and fairly the chances, risks and possible costs connected with a potential initiation of proceedings.”

“Being a father of two boys, I enjoy spending spare time with my family, preferably by doing sports.”
