Fernández’s aunt, Juanita Castro, sued Alina Fernández for libel and defamation over passages in her autobiography about Juanita and Fidel’s parents, Ángel Castro and Lina Ruz. In 2005, a Spanish court ordered Fernández and Plaza & Janes, the Barcelona Random House publisher, to pay US$45,000 to Juanita Castro, who said the book defamed her family: “People who were eating off Fidel’s plate yesterday come here and want money and power, so they say whatever they want, even if it’s not true… Part of my family was responsible for a lot of suffering in Cuba — you can’t change that,” she said. “But nobody has the right to offend Fidel’s family. Insult Fidel — there’s plenty to say.” An English version, published under the title Castro’s Daughter: An Exile’s Memoir of Cuba, omits the offending passages.

Fernández has one daughter. In an interview in 2008 with Foreign Policy magazine, she said she had been closer to her uncle, Raúl Castro, than she was to her father. She said Raúl Castro, who succeeded her father as the Cuban president, had helped her on several occasions. “He was the person to whom you could go to and ask for help every time you had a practical problem. I personally asked for his help a couple of times, and he always helped me immediately. In the family he was the only help you could find. On these kinds of issues, Fidel was totally unhelpful.”
