Under Illinois divorce law, the state follows a no-fault system—meaning infidelity alone typically does not determine outcomes like property division in Illinois.
But that doesn’t mean it’s irrelevant.
In certain situations, it can still have an impact—especially if:
Marital funds were spent on an affair (which may affect financial decisions)
It influences parenting concerns in Illinois child custody matters
It becomes part of a broader pattern of behavior
