I know this question has been explored a bit, but I would like to hear of people's experience in this regard.
I will be applying for citizenship soon and I understand that the UK has a one name policy, which is fine, except that name changes are not allowed in my country of origin. What is allowed is to request a name 'correction' through a court proceeding based on for example an issue with paternity, or a spelling mistake. In this case, if the court awards the correction (possibly after years in court) then the name is changed in the civil register as if that first name never existed. Marriage is not allowed as a reason to request a name correction. In other words, it is almost impossible to have my name changed officially in my passport.
I was wondering: 1) does the UK allow for the citizenship certificate to be issued in my married name given that I have used it for literally ALL purposes for the past 6 years? In fact, I never used my maiden name for ANY purpose at all in the UK.
2) Would submitting an affidavit and a letter by notorized legal professional citing the law and explaining the impossibility of name change enable me to get my citizenship certificate in my married name?
What is the best approach moving forward? I don't want to end up with a name I never used before. In fact, I never even used my last name in my country of origin: there we have several names as last names (father, grandfather, great grandfather) and the idea of a surname doesn't exist. So I always used one name for all purposes, while the UK uses the very last name listed among those names, which I never ever used in my life...

I also don't want this issue to cause delays. So based on your experiences what is the best approach in this regard? Thank you
