In Illinois, a dissolution of marriage can be granted based on irreconcilable differences. This means neither party needs to prove wrongdoing by the other to obtain a divorce. The court can dissolve the marriage if it finds that irreconcilable differences have caused the irretrievable breakdown of the marriage, that efforts at reconciliation have failed, or that future attempts at reconciliation would be impracticable and not in the best interests of the family.
This framework simplifies the divorce process by removing the necessity to assign blame. Historically, divorce laws often required proof of fault, such as adultery or abuse, which could be adversarial and emotionally damaging. The current system seeks to reduce conflict and allow couples to dissolve their marriage with less acrimony, potentially leading to more amicable settlements regarding property division, child custody, and support.
