The internet is flooded with the suggestions on how to change the date on your birth certificate. I was, also, looking for the same solution. Undoubtedly, forums and websites have certain defined steps. But, when it comes to viability, they seem not-so-concrete.  The discrepancies are laid somewhere in the steps. I wanted the NRI solution regarding the birth proof. This want pushed me to keep exploring over and over on the web because my cousin was unable to apply for the study visa due to that error.

Finally, I got the solution. Here is what I got to know and subsequently, executed these steps to rectify incorrect date on the certificate of birth.

How to Rectify Incorrect Date in Your Birth Certificate:

I got this answer in a forum wherein lawyers participate in the online discussion. This fact gave me a push to believe in what they suggest. However, it was tough to pick up the most suitable answer that can help me. But, I tried and emerged a winner at the end.

1. Visit Municipal Corporation: This is the first step that directs you to visit the Municipal Corporation office nearby your house. In my case, my cousin was a resident of the south Delhi. So, he visited the MCD or Municipal Corporation of Delhi for the date of birth certificate correction legally. It’s the authority that administers this matter, along with many other documentation matters associated with the civilians of that state/union territory.
2. Apply for correction: The registrar/sub-registrar of the Municipal Corporation holds the responsibility to look into this matter. You should request for the application form to place the request of changing the date of birth. Fill it duly.
3. Supporting Documents: Now, you should have to prove that your authentic birth date is some other. If you don’t have its documented proof, as it was with my cousin, don’t let the worry put your soul down. Enclose the existing birth certificate with the application form and an affidavit. Besides, attach these documents:

• Driving Licence
• Passport/PAN Card
• Voter ID/Ration Card
• Educational Certificate, like School Leaving Certificate
• Consent Letter from the hospital where you were born

Note: These documents won’t be necessary to show up because those who are born before 1986 don’t require any proof, except the affidavit. Even, you don’t need to submit the hospital discharge certificate. The sworn-statement would be enough to support on.

4. Bring an Affidavit: The affidavit is a sworn-document. Take a stamp paper, which costs INR 20 or may vary. Pen down all the changes in that stamp paper that you want to make in the birth proof. The composition of that affidavit should have the incorrect and the correct date in the form of an application. Input the name of your parents (mother and father) together with the address where you took birth.  
5. Notarization: Get it authorized by the notary officer of the court. This is what we call the ‘notarization’. The notary officer signs the affidavit while verifying the requested changes.
6. Verify with Municipal Corporation: Show the notarized affidavit to the Registrar or Sub-Registrar of the Municipal Corporation.
7. Issuance: The rectified birth proof will be issued on the very date when you visit the Municipal Corporation. However, you will have to pay certain fee for this service.

This process is more or less similar to the application of the Non-Availability of the Birth certificate or NABC. It’s an alternative document of the birth certificate that is issued in case you don’t have any birth proof.

Bear in the head that this document is vital to apply for the passport and visa. Any mistake in it is considered the discrepancy, which can lead to the rejection of your visa. Even, you will have to present it for the CENOMAR or bachelorhood certificate.
