Well, TMH is currently unemployable (I doubt whether even MacDonald's would give her a job, considering the disruption by media her presence would cause), she still needs a place to live and a means of feeding herself, etc. So far, her parents have apparently been willing to have her live with them but that's not a viable long term solution.
It is much easier not to think about money when one is not in dire need of it, in my opinion based on my own life experiences.
Regardless of KH's beliefs, until or unless TMH is convicted in a court of law, he implicitly agreed to certain things by marrying her. Among those things were an agreement that if they ever divorced, he and TMH would split their marital property in accordance to the law in the state in which they were living.
I am not a lawyer, all of the above is my opinion based on my own understanding of the law, which is incomplete and no doubt flawed.
