Is Digital Signatures Certificates are mandatory in case of Company registration?

Every Form and return prescribed under the Companies Act, 2013 needs to be filed with the digital signature of the managing director or director or manager or secretary of the Company, therefore, it is compulsorily required to obtain digital signatures of at least one director to digitally sign the e-Form (SPICe) 32 (however, if the name reservation is applied through Form RUN there is no requirement for DSC) and other documents. It may be noted that if the director or other persons covered are having digital signatures, his signatures may be used for the above said purposes and there is no need to take new signature again
