MCCD Forms
Form 4 and Form 4A
These are medical cause-of-death certificates. They are used for death registration. They are not the final government death certificate.
Form 4
Form 4 — Hospital death
Generally used when the death happens in a hospital or institution. It records the medical cause of death certified by the doctor.
Form 4A
Form 4A — Death outside hospital
Generally used when the death happens outside a hospital, such as at home, and a registered doctor certifies the medical cause.
Do not confuse: A cremation slip only proves final rites were completed. The official death certificate is issued by the local registrar or municipal authority after death registration.
