It can be an ugly situation when it happens, but unfortunately it's a reality: sometimes a spouse in a divorce will try to hide marital assets from the division of property. This kind of dishonest behavior is illegal in Illinois, but the risk of it happening is probably greater if one spouse has traditionally handled most of the financial matters.
Divorce can be rather messy in Illinois when property division is involved. Questions can arise surrounding just what is marital property and how it should be divided. In some cases, just how to divide up these properties and debts can end up leading to ongoing arguments with each spouse battling for their share in court.
