Property acquired after the marriage becomes jointly owned marital property. Simply having one name on land, a house, a vehicle, or a retirement account does not effect the determination in Illinois as to whether or not that property is marital or non-marital. The only document that matters it is your marriage license, after the signatures on that document, all subsequent acquisitions are marital property. The goal in a dissolution to divide property equitably. Dividing it equitably does not mean dividing it equally. Factors unique to your situation could create an unequal distribution, but still an equitable one. When a particular piece of property or item was acquired will help determine its marital or non-marital status. It is possible for property to be part marital, and part non-marital. This is especially true of pensions that began to accrue before the marriage. That pre-marital accrual should be set aside and not subject to division.
