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.  

This notification triggers a two-year period for negotiations between the UK and the other EU member states which should culminate in a withdrawal agreement.

Failing such an agreement, the UK will, in principle, leave the EU by operation of law after the two-year period (“hard Brexit”).

As this is the first time in the history of the EU that the article 50 exit procedure has been triggered, there is no clear and tested roadmap.

On 15 January 2019, the Brexit agreement reached between the EU and British government was rejected by UK Parliament. The British government is now working on an alternative proposal that would obtain parliamentary approval. However, it remains uncertain such approval will be obtained before the 29 March 2019 deadline. In the meantime, British government has issued several working papers on how a hard Brexit would take on form.

Depending on whether there will be a hard Brexit or a negotiated Brexit, the legal landscape will be quite different after 29 March 2019.

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

All sections on our Brexit page have been updated to reflect the hard Brexit working papers.
