The existing Norman customs and laws were allowed to continue and there was no attempt to introduce English law. The formerly split administrative system was replaced with a centralised legal system, of which the head was the King of England rather than the Duke of Normandy. The law was conducted through 12 jurats, constables () and a bailiff (). These titles have different meanings and duties to those in England. Any oppression by a bailiff or a warden was to be resolved locally or failing that, by appeal to the King who appointed commissioners to report on disputes.
