When to Register Birth
Birth Registration
Births should be registered within 14 days from the date of birth, including Sundays and public holidays.
Delayed Registration
Delayed registration refers to births registered after 14 days and within 42 days. Delayed registration is strongly discouraged.
Late Registration
If registration is done after 42 days, a letter of explanation stating the reason for late registration must be submitted for the Registrar/Registrar General's approval. Late registration cases can only be registered at ICA.
