If your spouse tries to conceal assets, it will not benefit them. Courts do not look favorably on dishonesty. Further, divorce attorneys can use a variety of tactics to uncover assets and income, such as formal or informal discovery requests, subpoenas, contempt motions, etc. Finally, even if you find out that your spouse concealed property after the divorce is final, the Court has the discretion to reopen the proceeding and distribute or redistribute property accordingly.
A Motion is a paper asking the Judge or Referee to decide an issue in a case. In a divorce matter, a Motion for Temporary Relief allows you to ask the court to issue a temporary order for child custody, child support, spousal support, and certain property issues. The Temporary Order allows you to get needed financial support while your case is pending in court. The Temporary order will expire when the final divorce decree is signed by the Judge and "entered" by court administration.
