Typically in New York any property purchased during the marriage, regardless of title, is considered marital. If you bought the NY home during the marriage it may be considered marital REGARDLESS of whether it is only in your name. So, if he buys a property in Florida during the marriage, in NY it will be viewed as marital REGARDLESS of whether your name is on it.
If you wanted to enter into a post-nup, and you both agree, you could try to carve out who owns what and define what property is marital in such an agreement.
Hope that helps. Good luck.
