    ,Sir, My case is somewhat peculiar. In a service export company, one local director and another 2 foreign directors. GST registration was made by giving the DSC of local Director & also as Authrorised signatory. Recently the local director has resigned. New local director was inducted because foreign directors cannot be authorised signatory as per rule. . In the GST portal if I try to fill it up the new director details, & finally it asks the left director’s DSC for approval. How can the left person can approve the new director.

    In second case, the local director was demised and how could I affix his DSC for new director DSC approval.
    I hope, you will get me solution for this and send me email to solve the same. I have verified with so many persons regarding this.
    I am not able to file the returns for the old months
    Expecting your earlier solutions and thanks in anticipation

    You can simply change the contact and email ID mention for the primary contact person without adding secondary person .
