Bluefin is suing a former IFA for £1m alleging that he poached clients and set up a new firm while still under contract.
Bluefin, the parent company of Layton Blackham Financial Services, has issued a High Court writ against former director Sean Condon, who resigned from Layton Blackham in December 2009.
The writ alleges that Condon set up a new firm, Yew Tree Financial Planning, while still working for Layton Blackham.
It claims that 54 out 62 clients then moved to Yew Tree.
Bluefin says it lost about £1m in profits as a result and is therefore suing Condon for the lost profits.
Condon declined to comment, and Bluefin was unavailable for comment.
