The difference is that there is written directive.
The spouse is trying to overturn that directive.
The child is trying to uphold it.
Wrong. Directive states wife makes decision.
If she were dead, your scenario would apply. But she is not.
If you read the story the wife did not even know how the daughter was trying to force this issue in court.
How much money will the daughter get when the man dies?
What if the daughter receives an inheritance when he dies? You see where this is headed? It's not a good place.
