Now a days, Registrar of company has provide online portal to upload all documents like balance sheet, annual return of company, compliance certificate etc online.
In this case if some one has a copy that is physically signed by the person then the company can use " sd/-" on sign site and can upload the document on ROC website, its ok..
But if some important documents are never physically signed and though the copies have been uploaded by mentioning "sd/-" then can we lodge a criminal complaint against the wrong doers.
