Australian family law is principally found in the federal "Family Law Act 1975" as well as in other laws and the common law and laws of equity, which affect the family and the relationship between those people, including when those relationships end. Most family law is practised in the Federal Circuit Court of Australia, Family Court of Australia or the Family Court of Western Australia depending on the location and complexity of the matter . Australia recognises marriages entered into overseas as well as divorces obtained overseas if they were effected in accordance with the laws of that country. Australian marriage and "matrimonial causes" are recognised by sections 51(xxi) and (xxii) of the Constitution of Australia and internationally by marriage law and conventions, such as the Hague Convention on Marriages (1978).
