Answer: Grounds for divorce are the legal reasons that you need to bring a case to court.
A judge cannot grant relief in any case until he or she first determines that certain necessary elements that pertain to that type of case have occurred. For example, if you sue someone for breach of contract, one such element would be to establish that the parties did indeed enter into a contract. Similarly, if you want to sue because of an auto accident, you have to be able to prove that the accident actually happened.
Divorce is a lawsuit just like any other lawsuit, and it requires proof of its vital elements, not the least of which is the ground (or legal reason) for the divorce. If the party that files for divorce fails to prove the grounds for divorce, the court will dismiss the case.
ILLINOIS DID NOT ELIMINATE GROUNDS FOR DIVORCE – IT MERELY ELIMINATED THE NEED TO PROVE FAULT FOR THE BREAKUP OF THE MARRIAGE.
As of January 1, 2016, Illinois eliminated all ten of its fault grounds for divorce and now has only one “no-fault” ground – Irreconcilable Differences.
To prove Irreconcilable Differences, the party seeking the divorce must merely testify that irreconcilable differences have caused the irretrievable breakdown of the marriage and that further attempts to save the marriage would be futile and not in the best interests of either party.
THE SPOUSES DO NOT NEED TO BE SEPARATED to use this ground unless one of the parties does not agree to the divorce. In this situation, the parties must be separated for six months, and then the resistant party cannot stop the divorce from happening. The six-month separation may not necessarily mean separate residences and need not occur before filing for divorce. It is only necessary that the parties have been separated for six months at the time of their trial or final hearing.
