Thank you each and every one for your valuable suggestions , I have taken Gazetted certification finally stuck with changing surname in marking certificates .

In my primary school they not ready to give due to at the time admission they are recorded at pasupuleti not sheikh . can you please suggest is there any other process is there to change surname in mark sheets.

I have to change from 10th to Post graduation, I am feeling it is not that easy in changing in mark sheets please help me for better possibilities .

Name is the most important data in our documents and changing that casually creates big problem in long run as the procedures for getting them corrected are very tedious and time taking so students should be very careful in maintaining their names and other credentials very carefully when applying for admission anywhere because once the name is registered in one form no one will agree to change it just like that. Matching of name, DOB, father's or mother's name etc over all our documents and educational credentials is a crucial requirement and we have to adhere to it.

You have only two documents where your correct surname (or the surname that you prefer) is reflecting and that is Voter Card and Ration Card. At the same time in all your other documents, which are of immense importance, it is mentioned wrongly and those documents are mark sheet, Aadhar card, bank accounts, Driving license etc. This is a quite messy situation and as many correction jobs are involved, it will be advisable to take help of an agent which are nowadays available everywhere to help people to get all these things rectified either online or physically. You have to pay their service charges for each of these jobs. Now based on the affidavit which you have got, you have to apply for Gazette notification of your name change as that is the most important procedure in our system. Once that is done which generally takes 20-25 days time, you have to pursue other jobs for changing your name in Aadhar card, bank accounts, and Driving licenses. The agent will get you all the forms and send his person to deposit them in person or do it online as the process is there and everywhere it will take some time for getting the corrections made. As regards your mark sheet you will have to show the affidavit copy and Gazette notification wherever you go for document verification and for all other documents as you will be able to get them in the revised name, there will not be any problem.
