Appeal for Property Reclamation as per Court Order

There are four sons: A, B, C, and D. D, who is aware of the court case and the properties involved, obtained signatures from A, B, and C under false pretenses. He then filed cases in court, which resulted in a declaration regarding the property in 2003. A, B, and C, unaware of the implications, agreed to D's actions and began cultivating the land. In 2018, A's daughter-in-law filed a case in the Tahsildar's office claiming ownership of the property. The Tahsildar sent a notice to B and C, stating that they needed to sign a document to register the property according to the court order. When B refused to sign, the Tahsildar and the lawyer pressured them, leading them to believe that A's daughter-in-law would register the property as per the court order for A. However, A's daughter-in-law unlawfully registered several properties belonging to B and C and combined some properties under both their names. In 2018, the Tahsildar declared that the registration was done with B and C's consent. Upon learning this, B filed a case in the AC court, but the lawyer did not submit the original documents. In 2023, the court dismissed the case due to the lack of an original copy of the court order and questioned why the properties had not been registered since 2003. Now, B has decided to appeal to the District Court. B wants to reclaim the properties as per the original court order. Please suggest what options are available.
