The members of the grouping are liable for its debts out of their own assets. However, a new member may, if the contract so permits, be exempted from debts arising prior to its entry into the grouping. The exemption decision must be published. They are jointly and severally liable, unless otherwise agreed with the third party co-contractor.
Creditors of the grouping may only pursue payment of debts against a member after having unsuccessfully served formal notice on the grouping by extrajudicial act.
