Under Illinois law, an inheritance (money, house, etc) is what is called non-marital property. That means that it does not belong to the marriage but is individually the property of the person who received the inheritance. If you inherited property, your spouse cannot claim it if you get divorced. However, sometimes people unintentionally do something to put an inheritance at risk at being lost in divorce. For example, if someone inherits money but puts that money into a house or into a joint bank account, that co-mingles the inheritance and may lose its status as non-marital property.
