17. Architects must, in the practice of their profession, assume full civil liability. They must not evade or attempt to evade professional liability or request that a client or person renounce any recourse in a case of professional negligence on their part. They may not include in a contract for professional services a clause that directly or indirectly excludes all or part of such liability. Similarly, they may not invoke the liability of the partnership or joint-stock company within which they carry on professional activities or that of another person also carrying on activities within the partnership or joint-stock company as a ground for excluding or limiting their personal liability.
