Generally the boards who issues SSC certificates , have a laid down procedure for correction of names. The same can be found out by visiting the school from where SSC was passed or the nearest office of the concerned board for knowing the actual procedure. It is always advisable to keep the documents ready and updated i.e. bearing the same name. It may or may not cause any problem later depending upon the organization in which the author will finally be able to find a job. In private smaller companies, it may not cause any problem or even in some Government organizations, filing an affidavit may work, but it will be wiser to get the name corrected in the certificate.
