Once a date of birth has been included in an official certificate, it cannot be easily changed again, like in a Transfer Certificate (TC).

Probably, the management of the school took the decision based on the school's policies and procedures, which might not have been accessible for her for modification.

What you can do in the following options: Call Higher Authorities:

If your school has an authority above it, such as DEO or Regional Director, then you can appeal to them and tell them that there was indeed some date mix-up or some problem in recording your date of birth while you were in the other school, supporting this with valid proof. Legal Option:

The final option would be to get legal counsel and proceed with a court petition to correct the situation. This option is often long-drawn and costly, so careful consideration should be in order.

Future Consequences:

While your TC carries a wrong date of birth for you, it may not pose a significant problem in the long run since it does not necessarily deter future academic or professional undertakings. Most institutions and many organizations would accept other proofs of your date of birth like that found on your birth certificate.

Also, you should consult with either a legal practitioner or an education specialist so that you clearly understand what procedures apply to your specific case and what the implications are in law.

They will be able to provide you with unique advice and directives on what to do next.
