In depth
Consular registration is the process by which a British citizen born abroad is registered at a UK consulate within 12 months of birth. Under the British Nationality Act 1981, consular registration can affect whether the child is a British citizen 'otherwise than by descent' (and can transmit to the next generation) or 'by descent' (and cannot).
Consular registration is also relevant for historic CBD cases under the British Nationality Acts of 1914, 1948, and 1981. Each Act has different rules about how consular registration affects citizenship transmission.
For modern cases, a British citizen born abroad to a British citizen parent who is 'British otherwise than by descent' is automatically British by descent — no consular registration required. However, registration can be useful for documentary proof.
