Earlier method of incorporation of OPC (under form INC 2) didn't required the digital signature of Professionals in the forms. I think that was done to make it possible/easier for any individual (promoter) named in the AOA with valid DIN and dsc, to incorporate the company themselves.
However, in the new form INC 29, the digital signature of professional appears to be mandatory even in case of OPC. Wonder why is that.

Very unhelpful reply, doesn't answer my question. Btw, today I filed for an OPC by the old way (INC-2), and got a required re-submission with a message that INC 8 (declaration by professional) have to be scanned too.
