Brexit - Are you ready?

Partager cette page

On 29 March 2017, UK Prime Minister Theresa May lodged a notification with the EU Council under Article 50(2) EU Treaty, i.e. the UK's formal notification of its intention to withdraw from the EU.  

The subsequent negotiations between the UK and the other EU member states led to a Withdrawal Agreement on 17 October 2019.  The European Parliament and the UK parliament approved this agreement. On 31 January 2020, the UK left the European Union and a transition period (also called implementation period) until 31 December 2020 started. The UK government has not asked any extension in time, meaning that the transition period ended on 31 December 2020.

During the transition period, the UK and the EU have negotiated a new trade agreement, the EU-UK Trade and Cooperation Agreement, establishing the relationship as from 1 January 2021. Certain parts of EU legislation temporarily remain applicable in the UK, although the UK is no longer a member of the EU and no longer takes part in EU decision-making procedures. Other parts cease to have effect in the UK.

As a transitional measure, Belgium has adopted the so-called “Brexit Law”, i.e. the Law of 3 April 2019 on the withdrawal of the United Kingdom from the European Union, as amended on 20 December 2020 and implemented by the Royal Decrees of 22 December 2020 on the entry into force of the Brexit Law and the transitional arrangement for insurance. 

On 6 March 2020, Belgium also adopted an additional Brexit law for employers in difficulties due to Brexit, with temporary measures aiming at safeguarding employment.

To help you prepare for the post-Brexit reality, Lydian has set up a Brexit team, composed of experts in the areas of law and the industries most affected by Brexit. 


Webinar Series II Brexit & Commercial contracts with UK companies

As the second Webinar in the 5-part Lydian Brexit Webinars series, the Commercial & Litigation team has reflected on the consequences of the Brexit from a contractual perspective. We discussed the applicable law and the international jurisdiction of courts, the enforcement of Belgian judgments in the United Kingdom (and vice versa) and cross-border insolvency. The impact on your commercial contracts with your UK partners was also explained, as well as which contractual clauses you are advised to (re)negotiate (such as force majeure, hardship, territoriality, price revision, liability...).

Webinar Series III Brexit : IP and data protection

Lydian IP and data protection team discussed the impact of Brexit on IP rights and data protection and more particularly after to the adoption of the EU-UK Trade Cooperation Agreement. 

Since 1st January, the EU rules in the field of European Union trademarks and Community designs do no longer apply to the United Kingdom. How do you need to adapt your IP protection and enforcement strategy?

Moreover, since that date, the UK has to be considered as a third country in terms of transfer of personal data. What does it mean concretely ? The situation was unclear until the adoption of the EU-UK Trade Cooperation Agreement. What does such agreement stipulate? Beside the data transfer issue, it is important to remind that UK companies’ activities can still fall within the territorial scope of application of the GDPR and have thus to put in place new measures, adapt their policies in order to be compliant. Which are these measures? 

Webinar Series IV Brexit : Corporate & Finance

During the 4th session of the Lydian Brexit Webinar series, our Corporate & Financial team provided you with an overview of the most important Brexit developments since 1 January 2021. For instance, how will cross-border mergers be impacted, and what is the latest on EU-UK cross-border restructurings? What are the consequences for listed companies? How can UK companies establish a branch in the EU (and vice versa) and what is the status of UK companies in Belgium and of Belgian companies in the UK? Furthermore, what are key considerations for banks, fund managers and investment service providers? What is the latest on regulatory and licencing needs for financial services firms to carry on their EU and/or UK business?
