This depends on whether the judgment of the court in 2006 has been delivered to you. If it has been delivered, and there is a time limit for execution according to the judgment, it has been three years, which has exceeded the time limit, and I am afraid there will be great trouble. Of course, if what the plaintiff said is true and the money is really in the court, the court should return it to you as long as the procedures at that time are checked. (The service methods mainly include direct service, mail service, lien service, entrusted service and announcement service. )
It is best to contact the judge in charge of the case (the clerk can also). Chaoyang court must have its own phone, but some courts are unwilling to answer the phone. Because of the long time, I suggest calling first and then going to court in person. Otherwise the court will drag on for a long time.
