A: The failure of the parties to sign will not affect the effectiveness of the court's judgment. Article 77 of the Civil Procedure Law stipulates that the service of litigation documents must have a receipt, and the addressee shall record the date of receipt, sign or seal it. The date of receipt by the addressee on the service receipt shall be the date of service. But this does not mean that the effectiveness of the judgment depends on whether the addressee signs the service receipt. The failure of the parties to sign does not affect the entry into force of the judgment. If Wang doesn't sign, it won't affect the validity of the court's judgment. If he refuses to accept the judgment, he should appeal. If he doesn't appeal after the appeal period, the court can enforce it after the judgment takes effect.
