This chapter discusses the law of persons. Prior to Exit Day, the private international law of matrimonial causes, parental responsibility, and maintenance was covered in part by two European Regulations: the Brussels II Regulation, Regulation (EC) 2201/2003, and the Maintenance Regulation, Regulation (EC) 4/2009. According to the Jurisdiction and Judgments (Family) (Amendment etc) (EU Exit) Regulations 2019, SI 2019 No 519, regulations 3 and 4, these two European Regulations will be revoked. Until Exit Day they are in full force and effect, but unless further legislative arrangements are made they will not apply to proceedings commenced before a English (or, where recognition is concerned, other Member State) court on or after Exit Day. SI 2019 No 519 makes consequential alterations to English law, which will come into effect on Exit Day.
