The Convention Providing a Uniform Law on the Form of an International Will, known as the Washington Convention ("the Convention"), was adopted in Washington DC on 26 October, 1973. The text comprises 16 articles stating the obligations of the contracting states, plus an Annex of 15 articles entitled Uniform Law on the Form of an International Will ("the Uniform Law"). The most significant obligation of the contracting states is to introduce the Uniform Law into their respective domestic legal systems.
Australia acceded to the Convention on 10 September, 2014 and it entered into force for Australia on 10 March, 2015. All Australian jurisdictions have amended their wills legislation to incorporate the Uniform Law as part of their law relating to wills. In South Australia, those amendments (Part 3A of the Wills Act 1936) commenced operation on 22 November, 2014.
