You do. When you have property that is in only one spouse’s name, the other spouse has a marital interest in that property. So if you have a retirement account in the name of only one party, that portion of it that was earned during the marriage is still marital property even if the other spouse’s name doesn’t appear on it. That also applies to real estate and other forms of assets such as cars and houses, so that if a house is paid for during a marriage or a car is paid for during a marriage, it also has a marital character.
