ARCHIVED: This Practice Note has been archived and is not maintained. The UK is no longer bound by the Rome Convention, as a matter of international law, having left the EU. However, the substantive rules continue to apply in some cases, ie if the contract was entered into between 1 April 1991 and 16 December 2009 and meets the criteria required under the act. Consequently, the substantive rules have been retained in the C(AL)A 1990 but they are subject to amendments set out in The Law Applicable to Contractual Obligations and Non–Contractual Obligations (Amendment etc) (EU Exit) Regulations 2019, SI 2019/834. For guidance on the current position, see Practice Note: Contracts (Applicable Law) Act 1990—application and interpretation.

To determine whether the applicable law regime under the convention applies, or whether some other regime applies, see Practice Note:
