Contrat fiduciaire
A contrat fiduciaire is a civil law analog of an English law trust. Popular in Luxembourg, Belgium, France and the French speaking parts of Switzerland.
However hotly a continental lawyer will protest otherwise — that the Roman law system knows no separation of beneficial and legal interest — that is exactly what this is: a contract in which one or more constituents transfer interests in property to a fiduciary who will manage them for the benefit of a beneficiary.
