http://www.ukbaptisms.net/cert_sample.htm The full certificate is an exact copy of the entry, showing the child's surname, forename(s), date of birth, sex, place of birth, the parent(s) name(s), their address and occupations at the time of registration. Full certificates are required for most legal purposes.
In addition, one can obtain a "short" birth certificate, which is an abstract of the original entry and only includes the surname, forename(s), date of birth, sex, registration district and sub-district in which the birth took place. No fee is chargeable for this certificate at the time of registration.
