Not sure if we're agreeing or not, apologies if so.
As long as now-husband's name stays the deed he will have legal rights to access the property even after divorce, regardless of his residency. If he wants to live at the house there is no legal mechanism to demand he vacate, never mind evict him. A divorce that somehow didn't reassign house ownership just makes him an owner-roommate.
If he's unwilling to leave voluntarily his name must be removed from the deed by Koushirou buying out or being assigned his share (after which he could be evicted). Failing that, the best she can do is to get her equity out by selling the property to a third party as part of the divorce.
This isn't entirely correct.
I was awarded the house in my divorce. Her name was on it. As soon as she agreed to that stipulation (divorce wasn't even final yet), my lawyer told me to change the locks.
She came back to the house to find out she was locked out, said that her name was still on the house. I told her to talk to her lawyer, because I talked to mine and this is what I was told to do. She stayed out of the house, and her name stayed on the deed until I was able to refinance a year or two later. The divorce decree functioned as superceding the deed.
