Usually if you want the house in a divorce... you have to take it over lock stock and barrel, including being required to refinance it in your name only. If alimony payments would cover it... it would work. If it doesn't you have to find cheaper accommodations. And that usually happens with BOTH parties after a divorce.

A lot depends on what state and country you lived in. And possible the circumstances of the divorce. I know people that divorced and while there was child support... beyond of a cash settlement there was no alimony. This was in Virginia.

I assume there hasn't been an actual divorce yet.

I don't know what OP is asking. How does she intend to get husband out of the house now that she has deserted him; and who does she think will help her with the house payments?

She needs to file for divorce and let the Court divide the property if they cannot agree.

At the moment he has grounds - abandonment of the marriage. I don't know that she does.
