New dob certificate

Hi,

We have adopted a baby girl (aged 3 months) from a relative. The adoption ceremony is completed and adoption deed is registered in sub-registrar office. Previously a birth certificate was issued by municipality with biological parent names in it. Now I want to get a new birth certificate with the changed parent names. What is the procedure for that? what are the required documents? Any useful websites to read about this procedure?

Best Regards,

Kesava
