Before you can get divorced, you need to understand the laws in your state. For example, the divorce laws in Illinois differ based on whether you go through a fault or no-fault divorce. Fault divorces involve a situation where one partner has committed adultery, physical or mental cruelty, or attempted murder. No-fault divorces are more commonly filed. They are useful for spouses who want to separate amicably for personal reasons, like irreconcilable differences or incompatibility.
Illinois is considered a “no-fault” state. This means anyone filing for divorce in Illinois must meet the following requirements:
•  You must have been a resident of Illinois for at least 90 days preceding the filing of the divorce.
•  You and your partner must have irreconcilable differences that have caused an irretrievable breakdown of your marriage.
•  You must have attempted reconciliation in the past.
•  It must be true that continuing reconciliation efforts would be impractical or not in the best interest of everyone involved.
