Town defender James Bolton has linked-up with former manager Neil Aspin by signing for Gateshead.
Bolton has agreed a three-year deal at the North_east club.
A compensation fee has to be agreed with Halifax, if not it will go to a tribunal.
Aspin signed Bolton three times when he was in charge at Halifax, twice on loan on once permanently.
Bolton won promotion to the Conference North in 2013, won the FA Trophy with Halifax last weekend and is also a regular for the England C side.
