Jurisdiction – the “Brexit transition period gap”
The Belgian Supreme Court has held that the Hague Convention 2005 continued to apply to the UK during the Brexit transition period
Our pan-European team of lawyers can advise you on complex legal issues for financial services companies post-Brexit.
At 11pm on 31 December 2020, the transition period ended and the UK entered into a new trading relationship with the EU under the EU-UK Trade and Cooperation Agreement ("TCA"). The deal applied provisionally from 1 January 2021, pending approval and ratification in the European Parliament. On 29 April 2021, the EU Council adopted a decision on the conclusion of the TCA, which was the last step for the EU to ratify the agreement. The TCA entered into force on 1 May 2021.
The UK has now left the EU Single Market and the Customs Union. The TCA represents a fundamental shift in the EU-UK relationship but does not address how financial services firms authorised in the UK access EU markets. Instead, firms must rely on equivalence decisions and future government regulations.
We've developed a useful online tool for financial services to continue doing business in the EU post-Brexit.
