When someone files for a no-fault divorce in Illinois, any marital misconduct, such as adultery or domestic abuse, becomes irrelevant in a divorce proceeding and may not be used to deny one spouse custody and visitation rights or prevent them from receiving equitable property distribution.
Under the current laws of the state, all Illinois divorces are granted on the "no-fault" grounds of irreconcilable differences. When filing a petition for dissolution of marriage, a spouse will state that their marriage has broken down beyond repair, and they will not need to give any other reasons for why they are seeking a divorce.
