If there is an insolvent person among co-inheritors liable for warranty, the portion of liability which such person is to bear is apportioned to those having the right to claim for reimbursement and other solvent co-inheritors in proportion to their inherited portions; provided, if the person who has the right to claim reimbursement fails to receive any reimbursement due to his or her own negligence, he or she may not make a demand upon the other co-inheritors to bear their portions.
