Oral law
code of conduct transmitted by oral tradition
An oral law are rules of human behavior in use in a given culture, religion or other group, which is transmitted by oral tradition and respected. Oral law is spoken, as opposed to statutory law, which is written down. Like customary law, oral laws depend not on legislation passed by a government, but rather tradition, custom and precedent.
Many cultures do have an oral law, while most legal systems of today have a formal written organisation.
