Amending A Birth Certificate
It is better to have a birth certificate copy, because this copy can be more easily replaced in the event of a loss. If for some reason a child needs their certificate to enroll in some type of youth sports, it is easier to breathe knowing that a copy is more easily obtained than an irreplaceable original.
Getting the certificate as an Adult : If you are over the age of 18 years and you don't have a birth certificate, you can apply for one from your area sub-chief's office. To apply for the certificate you need to have proof that validates your date of birth. This can be your identity card, baptism card, or a birth notification card from hospital.
