Architect (planner), engineer and general planner contracts are subject to the laws of the country in which the architect (planner), engineer or general planner usually resides or has his branch office (cf. IPRG 117).

For a construction manager contract, in the case of “local construction management” the characteristic services are provided for the matter (construction) at the (Swiss) location; as long as a law selection was not agreed to between the parties, the applicable law can be disputed; an individual ruling in concrete cases is unavoidable.

For an overall contract – as long as and to the extent that not law selection was made – the local law of the normal stay or rather the branch office of the service provider is applicable.
