A buyer is concerned about the legal validity of their sale deed, signed by an authorised director of a private limited company without the company's stamp or an attached copy of the resolution. While the Sub-Registrar may have the resolution, the absence of the company stamp and plot map in the registered deed raises questions. Experts advise that a company stamp is usually necessary, and the plot map should be attached or referenced. A rectification deed may be needed to include these missing documents.
