Customary Law:

Sometimes referred to as Traditional Law, Customary Law historically is the tradition of indigenous people, who generationally pass on the culture, customs, ethics and procedures on to the new generation, often orally, including song, dance and even story telling.

Overtime a legal custom is then established that follows the pattern of behaviour that can be objectively verified within a particular social setting. A claim can then be carried out in defence of "what has always been done is now accepted by law".

Marriage is one example of Customary Law. Age of consent is another. This is where the age of consent is agreed through history, custom and tradition, which is ethically the right thing to do.

Within history, most cultures celebrate coming of age, this is where all the rights and responsibilities are given to the child who has now become an adult.

Note: There is only one age of consent, within England it is 16. Other ages, such as 17, 18, and 21 are referred to as Legal Age of Majority, which is based in legislation, and have nothing to do with law.
