[quote]She is not really in contempt because she has listed the home with one realtor who is not listing it in MLS book.[/quote]

You mentioned payment in 120 days. Is that something in your decree or just your expectation? You did not mention a provision for selling the property. If there is one, with the half-hearted listing and high-ball price, you should file contempt and argue that she's not complying with the spirit of the requirement.

No. That's for child support and sometimes alimony but not for property issues.
