Klein was in the midst of renegotiating the Beatles' unsatisfactory recording agreements with EMI, Lennon told him of his plans to quit the group. It was agreed that this was the wrong time to either make or announce such a move. EMI was loath to re-negotiate, but their American subsidiary, Capitol Records, was so impressed by Abbey Road that they agreed to vastly improved royalty terms. McCartney joined his bandmates in endorsing the deal Klein had secured. Abbey Road proved to be the Beatles' last true collaboration, but Klein recognised an opportunity in the band's shelved January 1969 album and related documentary project, both titled Get Back, to get another album release out of the splintered group while also fulfilling their obligation to provide one more film to United Artists, the studio that had previously released both A Hard Day's Night and Help!

The Eastmans convinced McCartney to file suit against his former bandmates for dissolution of the Beatles' partnership, which he did on December 31, 1970. The judge ruled in McCartney's favor in March 1971. He decided that the combined financial affairs of the former Beatles should be placed in the care of a receiver until mutually acceptable terms for their break-up could be found. Klein thereby retained a position in the post-breakup solo careers of Harrison, Starr, and Lennon, but was no longer in charge of their affairs as a partnership.
