Is it permissible to sell land that a father registered in his daughter's name without his knowledge or consent, especially since he refuses to spend on her while she is ill, and claims she has no right over him, despite his extreme wealth?

A father must provide for his daughter who is in need of maintenance and medicine. If the father gifted a piece of land to his daughter and she took possession of it, then it is her property, and she has the right to dispose of it to spend on herself. However, if the land was written in her name as a will to be effective after his death, it is invalid because a will is not permissible for an heir. The daughter is permitted to take what suffices her from her father's money without his knowledge if he refuses to provide the obligatory maintenance. If she is unable to do so, she may take the matter to court. She must honor her father and accompany him with kindness, even if he is unjust.
