Ben Pauling, who saddled Willoughby Court to Neptune glory last season, has announced Daryl Jacob will become first choice jockey for the yard.
Pauling who also trains Barters Hill, is responsible for a growing yard in Gloucestershire as he picked up a record 32 wins.
The Bourton-On-The-Water handler has already enjoyed four wins this season, and is looking forward to his partnership with Jacob.
"We have had a fantastic few years with the yard growing season after season and I am not somebody who wanted to go down the route of using the best available," Pauling told the Racing Post.
"With Nico de Boinville being kept busy by Nicky Henderson and David Bass now being first choice at Kim Bailey's, I felt the yard needed some continuity and a jockey who would be available for much of the time.
Willoughby Court gave Ben Pauling his first Cheltenham Festival success, denying hot favourite Neon Wolf in the Neptune.
"The matter has been discussed with Simon Munir, Isaac Souede and their racing manager Anthony Bromley and an agreement has been reached, they will come first as far as Daryl is concerned but that means he is free to ride for us for the rest of the time."
"If there is a clash on big days like Saturdays we will cross that bridge when we get to it but for the most part Daryl will be fully available and I am looking forward to building on what the yard has already achieved in just a few seasons."
Jacob will still work for reigning champion trainer Nicky Henderson, and has ridden the likes of Bristol De Mai, Top Notch and L'Ami Serge in Simon Munir & Isaac Souede's famous green colours.
He hasn't tasted Cheltenham Festival glory since riding Lac Fontana to County Hurdle glory in 2014, and was narrowly beaten on two occasions last March.
Last season the man who saddled Neptune Collonges to Grand National success, enjoyed two Grade One successes with Top Notch in Scilly Isles Novices' Chase and Messire Des Obeaux in Newbury's Challow Hurdle.
The pair will team up with Calva D'Honore at Worcester tomorrow evening.
