When you apply for a British passport for the first time, you need to provide some documentation to prove you (or the child you are applying for) are, in fact, British: this can be a combination of grandparents' and parents' details, parents' immigration status if they are not British, etc.
But what when you renew a passport or change it? Do you need to provide the same data/ some data again, or not at all, because the passport office only checks your claim to British citizenship the first time? I'd hope it's the latter, but I'd like to be sure.
"Change" is the term used by the passport office for when you need to update a photo.
I am considering getting a new passport for DD, because she looks nothing like the 2-week in the photo and we were sort of told off at Gatwick because of this. I started the online application form, without submitting it (£ 46...), and the online form specifically asks for grandparents' details, even if this would not be DD's first passport.
Getting all these details would take me a while, and should, well, be irrelevant, because DD's British nationality has already been confirmed by the passport office - when she was issued her first passport. Can anyone confirm if this is the case? I'm hoping it's just some kind of IT glitch (the IT system should IMHO not have demanded the grandparents section at all for a renewal).
Thanks!
