After Fernández' death in 1986, a dispute over his will erupted, particularly concerning his stunning "fortress" home in the neighborhood of Coyoacan, in the south of Mexico City. Emilio died intestate, and his only surviving daughter, the writer Adela Fernandez y Fernandez, was automatically named the sole heir to the exclusion of Domínguez, who claimed property rights. According to Domínguez, Adela was not a biological daughter of Emilio, and he had never legally adopted her.[2] These details, and the legal situation, were never clarified as Adela died in 2013.[citation needed]
