Does anyone know the actual facts of this matter? If so, please set me straight.
I'm not saying that this alters the moral and ethical situation — just that it might explain some things.
You can have all of the joint assets reallocated to the two individuals. That protects the other spouse.
The case in question involved a man whose wife was in a home with Alzheimer’s, and was seeing another woman.
The case you stated is simply fraud, not adultery. It might land someone in jail though.
