344. What is matrimonial consent?
Matrimonial consent is given when a man and a woman manifest the will to give themselves to each other irrevocably in order to live a covenant of faithful and fruitful love.

For a valid marriage the consent must have as its object true Matrimony, and be a human act which is conscious and free and not determined by duress or coercion.
