When the decision of the members results from their consent expressed in a deed, this decision is mentioned on its date in the register provided for in Article R. 4381-43. The entry in the register must indicate the form, nature, purpose and signatories of the deed. The deed itself, if it is a private deed, or an authentic copy thereof, if it is a notarised deed, is kept by the company in such a way as to enable it to be consulted at the same time as the register of deliberations.
