We are specialists in property law

The firm of SIEGRIST & LAZZAROTTO specialises in property law. We assist our clients in all the legal procedures to do with the construction, management, ownership, financing or trading of a piece of property. The cases that we deal with are therefore mainly to do with civil law (real rights, inheritance law), contract law, administrative law (local planning law, environmental law, construction law, public procurement law) or following on from major infrastructure projects.


Our clients are traditionally private proprietors, public bodies, institutional investors, professional agents (architects, engineers, bailiffs, brokers, promoters) or businesses.
