For purposes of this statute, "right of first refusal," unless otherwise agreed upon by the parties, means that if a party intends to leave the minor child or children with a substitute child-care provider for a significant period of time, that party must first offer the other party an opportunity to personally care for the minor child or children.
If you have been following this act you will have noticed that the final language is actually different than how it was originally introduced in the Illinois legislature. Originally, the proposed change would have been mandatory on the court and spelled out that the time frame had to be more than four hours before the act was triggered. The statute that is now in effect at least leaves it up to the judge's discretion as the final arbiter of the best interest of the child in a custody dispute, but it leaves the "significant period of time" in which this child care would take place open to interpretation.
