Vining has bought the arm, which has offices in Paris and Lyon, for an undisclosed sum.
Mike Vining, managing director of the consultant, said: “The inclusion of Citex France within the group strengthens our service in one of the most relevant locations to Europe-wide business.”
Citex France will trade as Vining Citex, then will be renamed Vining Management SARL in August.
Vining was established in the mid-1990s. Clients include Deutsche Bank Real Estate, Unite and Munich Reinsurance.
