Notice to British-born parents applying to register the birth of a child.

Although we welcome applications to register the births of children born in Nigeria to British-born parents, you should be aware that this is not obligatory. A Registration certificate is a useful document to help establish a child's British nationality, but it is perfectly acceptable to apply directly for a British passport, without first registering the birth with us. Nevertheless, we recommend that British parents born outside of the UK, and those people currently working in Nigeria on UK Government service, should register their children's birth's using the forms available on this website.
