The answer is it depends on the situation. If the party maintains it separate than any accumulation of wealth and if it's a non-marital property, then the wealth that accumulates is non-marital property. There are situations in which if the other spouse contributes to the non-marital property, gives it time or effort or does their own money to contribute to that non-marital property to enhance the growth, then you could sort of have a situation where the growth may have a part that is not marital but, is marital. I'm sorry for that matter, but for the most part non-marital property or any wealth it accumulates remains non-marital.
