Dear Charu, when we upload the form with the MCA, we have to put the digital signatures of Director and the Professional. What it mean is that they themselves are affixing the digital signatures as no person other than authorised can use the digital signatures. So if the directors are outside the India, then the person uploading the form should wait to come and after the director return to India, director themselve should affix the signature and the form should be filed. Other way out can be to mail the unsigned e form and the directors at their end will affix the dsc and the form can be uplaoded after receiving the mail from director, by the Professional to avoid the additional filing Fees.
Now talk about the the word"Sd/-", in FAQ of MCA it says that attachments in respect of Form 23 AC and ACA can only be FILED BY USING THE WORD "Sd/-' and teh Annual return has to be get signed and to be scanned. Moreover the word "Sd/-" can be used only when the Company has the physically signed documents i.e. balance sheet and profit and loss accounts but to avoid the heavy size problems the company is converting the word file into pdf by using the word 'Sd/-'. Even when the word "Sd/-" is used then keep in mind that you will not scan the document rather to convert the same into PDF.
Moreover teh using of word "Sd/-' is applicable only for Annual Filing and not for other E Forms.
