Non-liability contract is an agreement based on which the parties annul the future possible civil liability. With such a condition the obligor (engagé) is exempted from the liability that would occur for him in future. Nowadays the application of non-liability is prevalent in internal and international contracts. Today the principle of validity of non-liability is accepted by most countries across the world though in some cases like intentional damage it is invalid because no one is allowed to set a condition that ensures his non-liability before his intentional actions. Generally speaking, in all cases where non-liability is against the social order it is annulled. Whenever non-liability is on the right track it annuls the liabilities of the obligor and leaves no room for the damaged person to ask compensation from the damage doer.
