Gers chief executive Charles Green is using the services of the agent, who was banned in 2008 for 18 months and fined £300,000 for a number of misconduct charges relating to how he acquired the right to represent Manchester United and England striker Wayne Rooney six years earlier.
A spokesman for Rangers told Press Association Sport: "Paul Stretford is assisting the club."
Stretford's link with the Ibrox club is revealed as Ally McCoist prepares to bolster his squad for life in the Irn-Bru Third Division next season.
On acceptance of Scottish Football Association membership, still to be ratified, the Light Blues' boss will have until September 1 to sign players before a 12-month transfer embargo begins.
Rangers fans may wonder about Stretford's remit given the club's new league status and the apparent lack of cash available at Ibrox to bring players in, but confirmation of the Englishman's involvement comes while Green continues to challenge the decisions of the players who walked away from the club this summer.
The two clubs agreed an undisclosed fee for the Northern Irishman, reported as £800,000, although that is disputed by the English club.
On the advice of the players union, PFA Scotland, Davis, Steven Naismith, Jamie Ness, Kyle Lafferty and Steven Whittaker rejected the opportunity to the transfer of their contracts to Green's newco.
