1. Maria is an only child. Her mother died when she was eight years old. Now, seven years later, her father is engaged to remarry, and Maria objects. She is afraid that her father's new wife will come between her and her father and that the new wife will end up with the family home after her father dies. Ethically, should Maria try to persuade her father not to marry? Is there a legal device that would help resolve part of her worries?
