Abstract
"Director's Guarantee" is an expression reserved by doctrine to refer to the surety given by a director to secure the debts of his company. The employment of this phrase is useful insofar as the director's guarantee has always had an intermediary status : he cannot be considered to be either as simple consumer because he's contracted for the purposes of the director's professional activity, nor as a professional contracting in his or her field. Traditionally, case law has considered director's guarantees as informed sureties. In fact, they embody the archetype. Since the 1970's, legislative reforms have regularly complicated this court-made definition of the director's guarantee. The French Economic Initiative Act of 1 August 2003 launched a new era for director's guarantees, making them ordinary individuals of surety law. Later legislative actions even had to note that director's guarantees are paradoxically better protected than non-director's guarantees, thereby weakening the function of this surety that is to provide business credit.
