Noahide legal rulings are composed of three kinds of rulings.
* [[The Seven Laws]] - the basis of all proper religion belief and beliefconduct.* [[Subdividing the Seven Laws|Expansion of the Seven Laws]] - derived laws from details concerning the application of the first basic sevenBnei Noah commandments, either through logic or comparison with as well as injunctions of the Jewish lawwhich Bnei Noah are allowed to take upon themselves, or forbidden.* [[National LawsCivil laws]] - The Areas not covered by the Bnei Noah legislation does not regulate commandments such as inheritances ,contracts and other civil matters which are left for a particular country to judge be adjudicated, each nation according to their its own laws and customs.
There is an opinion that there should not be one Code of Law for Noahides, but perhaps 'seventy' codes of law for each of the ''[[seventy nations]]'', where each Code of Law would reflect the national character of that nation. In this case, the details of the decisions -- particularly where they concern the third type of Noahide law above -- may be different from nation to nation.
Rabbi [[Yaakov Anatoli]] (1194-1256) in ''HaMelamed'' put it this way: When the Noahites were enjoined concerning Justice, they were put under obligation to create legal arrangements .... It is incumbent on the judges to draw up rules of equity that shall be appropriate for that particular country, as exemplified by the manner in which this matter is handled currently by the nations, severally. Likewise, it is incumbent upon merchants and upon the members of the trades to establish regulations for themselves... and whatever emerges as the law in this manner is law, as much as that which is written in the Bible. Furthermore, anyone violating this law violates Scripture, because Scripture commands the individual to accept the decisions of the contemporary jurists. The dictum, "The law of the land is the Law," relates to this concept.<ref>Quoted by Reuben Margolioth, Margolioth Hayarn. Jerusalem: Mosad Harav Kook, 1958, volume 11, page 20.
