Hywel ap Cadell,
Welsh Medieval Law: The Laws of Howell the Good…
(1909)
“ No one is to make a contract for another without his permission ; neither a father for his son ; nor a son for his father ; because a contract does not last except during the life of him who makes it. Although a contract be made in opposition to law, it must be observed. A contract annuls a custom. Stronger is contract than justice. [368] If a person promise chattels to another in the presence of witnesses and be afterwards desirous of denying it, it is not possible, unless the other's witnesses fail him. If he promise with no one in the place, let him swear on his own oath if he will. ”
