In the state of Illinois, you need grounds to obtain a divorce. If everything is going fine in the marriage and neither party is at fault and neither party wants a divorce, that’s going to be very tough to get one without grounds. The most common ground for divorce is irreconcilable differences. Irreconcilable differences is where the parties have lived separate and apart for a period in excess of six months whereby the parties just have differences that can’t be resolved. Those differences have led to the retrievable breakdown of the marriage. Attempts to reconcile the marriage have not been successful. And the parties consider the marriage is over and it’s in the best interest of the parties and the family to end the marriage.
