Although being the sole owner on the title may give the wife some small advantage when arguing about who should get the home after the divorce concludes, the home was purchased during the marriage and, under the given facts, is a marital asset. The wife can't simply evict her husband -- she will need to get an order for exclusive possession from the divorce court.
The best approach here, if possible, is for the husband and wife to negotiate the issue. Perhaps the husband doesn't want the home, and will agree to move out by an agreed date.
