Austria > Banking and finance Tier 2

CMS Reich-Rohrwig Hainz Rechtsanwälte GmbH has carved out a strong practice handling finance transactions as well as regulatory work with Günther Hanslik, who co-heads the practice with Martin Zuffer, being the main contact for the former and Zuffer the key for the latter. In the transactional space, instructions include acquisition finance, corporate lending, real estate and project finance and routinely contain cross-border elements, most notably within the CEE and SEE regions. The team's cross-border offering and English law capabilities were further strengthened by the arrival of Marcell Clark from Dentons in August 2020, while Stefan Paulmayer brought additional expertise in securitisation, banking supervisory law and fintech but also handles restructuring-related work; also an area of expertise for Hanslik. Paulmayer joined in January 2020 from PwC Legal Austria-oehner & partner. He is particularly active for financial services providers but also acts for borrowers. Walter Gapp, who joined in March 2020 from Rautner Rechtsanwälte GmbH, predominantly handles capital markets work but also provides banking regulatory advice.

Practice head(s):

Günther Hanslik; Martin Zuffer


‘Very experienced, very good knowledge of the market, fair and calm negotiators, not unnecessarily dramatising things. Good solutions which can be put into practice.’
