Legal Question in Family Law in Illinois

There are situations where a judge can order a person to sign a judgment. You have provided no underlying facts to provide a basis to question the judge's action.

A divorce decree is a Judgment of the Court. It does not require the signature of either party. If one party is refusing to sign the Marital Settlement Agreement, the case goes to trial and the Judge will determine how the marital estate and custody issued will be determined. So I guess the answer to your question is No.
