In March 1925 Curzon suffered a severe haemorrhage of the bladder. Surgery was unsuccessful and he died in London on 20 March 1925 at the age of 66. His coffin, made from the same tree at Kedleston that had encased his first wife, Mary, was taken to Westminster Abbey and from there to his ancestral home in Derbyshire, where he was interred beside Mary in the family vault at All Saints Church on 26 March. In his will, proven on 22 July, Curzon bequeathed his estate to his wife and his brother Francis; his estate was valued for probate at £343,279 10s. 4d. (roughly equivalent to £ in ).
