There is no provision in the Act that the witness should only be a professional.
However, there is a reportedily fraud couple of years back before MCA-21 era when a company was incorporated by the ROC based on the witness done by a non-professional (i.e. his identity is not known anywhere). In this case the fraud was to the extend that both the subscribers were non-existing and the witness shown was also non-existing. When such company defaulted in filing the BS/ AR, no one was traceable. Now what to do ?
After that the ROC obtained guidance from the Ministry and the reply recd was that if the witness to the subscriber is a professional (who is always searchable) it shall be better to have someone to give explanation. After that ROC started insisting that the witness should only be a professional. Important is that only few ROC are following this practice.
Hence as per law WITNESS TO MEMORANDUM AND ARTICLES OF NEWLY INCORPORATING COMPANY, IT IS NOT NECESSARY ONE SHOULD BE A PRACTISING PROFESSIONAL OR EVEN OTHERS(LIKE PROFESSIONALS IN SERVICE OR EVEN LAYMAN) CAN ALSO DO IT. But few ROC still insist for a professional witness to MOA as a safe practice only.
