Brexit is a trading and commercial opportunity for the countries of the Commonwealth, as it makes it likely that, for many, their access to United Kingdom (UK) markets will improve significantly. The question addressed in this article is whether, to support more open and trading relationships, Brexit also presents opportunities for the development of the private international law of Commonwealth countries – including the UK.Focusing on Australia, Canada, New Zealand and Singapore, as well as the UK, an account is given of the relationship between the different systems of private international law in these Commonwealth countries in the period of the UK’s membership of the European Union (EU). Accordingly, consideration is given to the Europeanisation of UK private international law and its resistance in other parts of the Commonwealth. The continuing lead that English adjudication has given to private international law in the Commonwealth and, yet, the greater fragmentation of that law while the UK was in the EU are also discussed. The conclusion considers the need to improve the cross-border enforcement of judgments within the Commonwealth, and the example given in that respect by its federations and the trans-Tasman market. Possible directions that the cross-border enforcement of judgments could take in the Commonwealth are explored.

对于英联邦国家来说，英国脱欧是一个贸易和商业机会，因为这可能使许多人进入英国市场的机会大大改善。本文所要解决的问题是，为支持更开放的贸易关系，英国退欧是否也为英联邦国家（包括英国）的国际私法发展提供了机遇。作为英国，在英国成为欧盟（EU）期间，这些英联邦国家的不同国际私法体系之间的关系得到了说明。因此，考虑了英国国际私法的欧洲化及其在英联邦其他地区的抵制。英国的裁决在英联邦的国际私法中继续发挥着带头作用，然而，也讨论了英国在欧盟时该法的更大分散性。结论认为有必要改善英联邦内部的跨境执行，并在这方面以联邦和跨塔斯曼市场为例进行说明。探索了英联邦的跨境执行判决可能采取的方向。在这方面，它的联合会和塔斯曼海峡市场就是一个例子。探索了英联邦的跨境执行判决可能采取的方向。在这方面，它的联合会和塔斯曼海峡市场就是一个例子。探索了英联邦的跨境执行判决可能采取的方向。
