In the last years of his life Shaffer had an extramarital relationship with Marie Josette "JoJo" Capece-Minutolo when in London. Cilento did not accompany Shaffer to England but remained in Australia. After Shaffer's death, Capece-Minutolo made a claim on his estate in the British High Court, arguing that Shaffer had intended to divorce Cilento and marry her and that he had given her an engagement ring. The Shaffer estate argued that Shaffer had no desire to end his marriage to Cilento. The British judge found that despite Shaffer's being in "an intimate and loving relationship" with Capece in London, Shaffer (and his estate) were not legally domiciled in the United Kingdom at the time of his death and that therefore Capece-Minutolo had no legal claims on his estate, other than any bequest in Shaffer's will (which had been changed in 1999).
