The Ellen G. White® Estate, Incorporated, is an organization created by the last will and testament of Ellen G. White to act as her agent in the custody of her writings, handling her properties, "conducting the business thereof," "securing the printing of new translations," and the "printing of compilations from my manuscripts." Her will, dated Feb. 9, 1912 (printed in its entirety as Appendix N in Messenger of the Lord, by Herbert E. Douglass) named five church leaders to serve as a board of trustees: Arthur G. Daniells, president of the General Conference; William C. White, her son; Clarence C. Crisler, a secretary; Charles H. Jones, manager of the Pacific Press; and Francis M. Wilcox, editor of the Review and Herald. Four of the five were members of the Executive Committee of the General Conference.

Appointment of the trustees was for life, Ellen White providing that "if a vacancy shall occur for any reason among said trustees, or their successors, a majority of the surviving or remaining trustees are hereby empowered and directed to fill such vacancy by the appointment of some other fit person"; or if this provision were to fail, the General Conference Executive Committee should appoint someone to fill such a vacancy. The will dedicated the major portion of the existing and potential royalty incomes from her books to the work of the trustees. (For additional information, see Appendix B, "The Settlement of Ellen G. White's Estate," in volume 6 of A. L. White's biography of Ellen White, Ellen G. White: The Later Elmshaven Years.)
