A "tsunami" of British lawyers have flocked to register on the Irish roll of solicitors this year following the UK's vote to leave the EU.
By the end of the year, the Law Society of Ireland will welcome a record 1,347 new solicitors to it books, beating the previous record set in 2008 by more than 500.
The estimated figure is a 275 per cent increase on British members who joined in 2015.
"The tsunami of new solicitors has been caused by the Brexit-driven transfer decisions of some 810 England and Wales-qualified solicitors to take out a second jurisdictional qualification, in Ireland," Law Society of Ireland director general Ken Murphy said.
"This they have been perfectly entitled to do since the mutual-recognition regime between the two jurisdictions was first put in place since 1991."
Mickael Laurans, head of international at the Law Society of England and Wales, said: "Our member firms, like all well-run businesses, are addressing the potential risks caused by the uncertainties arising from the Brexit process and, in doing so, have asked a number of their lawyers to register in Eire where we have reciprocal rights.
"In a worst case scenario, post-Brexit, UK lawyers would run the risk of losing the ability to advise on EU competition and regulatory law. The Law Society of England and Wales is urging the UK government to maintain the current level of rights of access."
