Marital property doesn’t include property you owned prior to the marriage. However, you’ll be required to prove that the property was separate property. Additionally, your spouse may try to argue that the property was commingled with the marital property so as to become a part of the marital estate. Gifts or inheritances directly to one spouse are also excluded from marital property. As long as the property remains reasonably separate, separate property remains outside of the marital estate even if it changes form or appreciates in value.
