How a house that is in the name of only one spouse would be divided depends upon such factors as how the house was acquired, the duration of the marriage, and the state at issue. If the parties were married a long time, put a lot of money into the mortgage, repairs and improvements, sometimes the marital home will be held to have "merged" into the marital estate. If the house was purchased with marital assets, even if for some reason only one spouse is named, courts would typically view it as a marital asset.
