De acordo com o livro, a Ordem da Fênix ofereceu sua proteção aos Dursleys:
Harry Potter: "The Order is sure Voldemort will target you, whether to torture you to try and find out where I am, or because he thinks by holding you hostage I'd come and try to rescue you. <...> You've got to go into hiding and the Order wants to help. You're being offered serious protection, the best there is." - Harry Potter and the Deathly Hallows, chapter 1
Eles suspeitaram que o Ministério da Magia foi infiltrado:
Até onde eu sei, não há informações sobre a vida de Dursleys durante o ano anterior à queda de Voldemort. Falando sobre seu futuro, a J.K.Rowling só confirmou o seguinte:"I thought there was a Ministry of Magic?" asked Vernon Dursley abruptly. "There is," said Harry, surprised. "Well, then, why can't they protect us? It seems to me that, as innocent victims, guilty of nothing more than harboring a marked man, we ought to qualify for government protection!" Harry laughed; he could not help himself. It was so very typical of his uncle to put his hopes in the establishment, even within this world that he despised and mistrusted. "You heard what Mr. Weasley and Kingsley said," Harry replied. "We think the Ministry has been infiltrated." - Harry Potter and the Deathly Hallows, chapter 1
"Harry and Dudley would still see each other enough to be on Christmas-card terms, but they would visit more out of a sense of duty and sit in silence so that their children could see their cousins." - Open Book Tour, Morning Appearance, NYC, October 19, 2007
Assim, pelo menos Dudley Dursley está vivo. Eu suponho que outros Dursleys também tenham sobrevivido. Depois que Voldemort morresse ou pouco tempo depois, eles poderiam voltar para casa.
