On 28 December 2018, the UK deposited its instrument of accession to the Hague Convention on Choice of Court Agreements 2005. The Convention will therefore come into force for the UK on 1 April 2019, in accordance with article 31 of the Convention which provides for it to enter into force on the first day of the month following the expiration of three months after the relevant instrument is deposited.
The government had previously declared its intention to sign up to the Convention with effect from 1 April, in case the draft withdrawal agreement that has been agreed between the UK and the EU is not ultimately entered into. The deposit of the instrument of accession now assures that this will take place.
If the withdrawal agreement is entered into, the UK will withdraw the instrument of accession. In that case, during the transition period provided for in the withdrawal agreement, until the end of December 2020, the UK will be treated as an EU member state for the purposes of the Convention.
