Question juridique clé
Whether the defendants were personally bound as solidary co-debtors or only by suretyship
Solution extraite
The defendants assumed a personal solidary obligation, not a suretyship.
Motifs extraits
The signed credit documents and the use of the term 'solidary co-debtors' showed an agreement to be liable in the same way as the company. Given their direct economic interest as shareholders and directors financing their own business, the guarantee was not subject to suretyship formalities.
