If I have been married 20 years and purchased a mortgage in my name only 10 years ago, who gets the house?

If a house is purchased during the course of the marriage, it is normally considered to be marital property, regardless of whether the mortgage is in the Husband or Wife's name.  To resolve the issue of property division, the parties may agree on who retains the marital home.  If the parties are unable to agree, the court could award the property to either one of the parties or order that the house is placed on the market and sold.
