12th mark sheet mother name is right. If I want to correct my mother name then what can I do and how much time it's take

Hello dear student,

dear student I would like to ask you if the name of your mother which is put in your class 10th marksheet is right or the the name which is put in class 12th marksheet it is right? Please answer me to this question so that I can help you further . And just for your information I would like to tell you that always the information that is there in your class 10th marksheet is considered as valid and it is also considered as your birth certificat. if your mother's name in your class 10th marksheet is right then there is no problem which is that will be considered valid . as reference class 10th marksheet is only asked and not class 12th marksheet but still if there is a problem in the name of your mother in your class 10th marksheet then you can get it corrected with the help of your School as you have to write a application to the CBSE board asking them to correct the name of your mother providing them the proof . And kindly answer me what I have asked for so that I can help you properly.

Thank you
