Disposing of property before mediation

Can the party that has possession of the home (R.O. in place) dispose of property before mediation? When parties went over ED items in mediation, the party did not disclose of disposing property (line item) until an agreement was made and signed. Is there any recourse now since judge has signed the agreement of ED?

If they agreed to give it to you then I’d say they should compensate you for it if they no longer have it.
