Understanding the differences between Aboriginal Law and Indigenous Law is the first step. 

Aboriginal law is a body of law, made by the courts and legislatures, that largely deals with the unique constitutional rights of Aboriginal peoples and the relationship between Aboriginal peoples and the Crown. Aboriginal law is largely found in colonial instruments (such as the Royal Proclamation of 1763, the Constitution Acts of 1867 and 1982 and the Indian Act) and court decisions, but also includes sources of Indigenous law.

Indigenous law consists of legal orders which are rooted in Indigenous societies themselves. It arises from communities and First Nation groups across the country, such as Nuu Chah Nulth, Haida, Coast Salish, Tsimshian, Heiltsuk, and may include relationships to the land, the spirit world, creation stories, customs, processes of deliberation and persuasion, codes of conduct, rules, teachings and axioms for living and governing. – From Making Space for Indigenous Law (Estella White (Charleson) - Hee Naih Cha Chist)
