NoteForeign nationals who apply to become British citizens may be registered or naturalised in their married name. However, if a new citizen wants a British passport in their married name they must change the name on their other passport(s), travel documents and national identity card(s) to reflect their married name before submitting their application. Exceptions to this approach are set out in paragraphs 18 to 28 below
Recognised multiple namesA Home Office document which is a record of an event, such as a birth certificate or a naturalisation certificate, cannot normally be amended unless there are exceptional circumstances
So para 26 clearly states an exception if it can be proven that both names are in use.26.
British citizens who hold warranted titles or are known more commonly by their stage or professional name may use both names. An observation may be included in their passport
It needs to be established if this can apply to one or other of a married & a maiden name being used in a professional context.
Adoption, Birth and Naturalisation certificates
Para 28 seems to mean that a naturalisation certification captures someone's name at a point in time, (on the day of the oath-taking ceremony).28.
These documents are records of events and changes to these records are not covered by this policy
It doesn't mean a person's name can never be changed after naturalisation; for example by changing it by deed poll.
And if a name is changed at a later date the naturalisation certificate will then be different because it records an event &, as per the note (above), such a certificate can never normally be changed.
This seems to mean even this new policy would allow someone to apply for a passport in their maiden name even if they were naturalised in their married name.
It may be that a Deed Poll would (unusually) have to be obtained to revert to the maiden name, rather than the usual step of simply presenting a marriage certificate to show the link between the 2 names.
It may mean that an original passport application made in the married name would have to be sacrificed;
meaning more stress & hassle, further delay, more cost, more inconvenience (a new application form & another visit to the counter-signatory), etc.
However it seems it could be a way forwards for those married ladies recently naturalised as a UK citizen using their married name who are currently trapped by the new UK policy;
i.e. if their dual country does not or will not allow cancellation or change of an original passport held in the maiden name (or the country prohibits revoking of original citizenship or the dual citizen does not wish to give up their original citizenship).
Note, I am not a lawyer and this is not legal advice, it just represents my researches and my attempt at logical reasoning to solve this catch-22 scenario.
So further advice should be taken before acting.
