Spokespeople for Pease and Henderson confirmed the filing has been made and declined to make any further comment on the matter.
The claim centres on £2.7m ($3.7m, €3.4m) which Pease believes he is contractually owed for his work at Henderson between 2012 and 2014.
Pease ran his European Special Situations fund under the Henderson banner between 2009 and 2014 and according to the filing the fund clocked up nearly £14m in management fees, to which he was contractually entitled to half.
This is the first public indication of any discord between Pease and his former professional home. He left on seemingly good terms last year to set up Crux Asset Management, taking the fund with him.
Pease’s fund was a standout performer for Henderson during the period that he worked there after his former firm New Star was taken over.
