Also, I would like to add something here.
Assuming unmarried partner but British Citizen.
The online form asks about the nationality of the partner. Once you input “British”, the form automatically assumes that one is applying via Section 6(2) and generates the checklist accordingly which asks about the “marriage certificate” and “British passport proof of the partner.”
As Vinny said,
The unmarried partner of a British citizen cannot benefit from Section 6(2).
So for instances like above, one should explain in the cover letter that the application to be considered via Section 6(1) instead.
Personal experience:
I was in a similar situation. Since I am religiously married only, my British wife is considered as an unmarried partner according to British Law.
Since she has dual nationality, I only input Pakistan as her nationality so the checklist generated is correct for my circumstance.
Also, I explained the situation regarding her nationality in the cover letter and mentioned that the application to be considered via Section 6(1) instead as I do not qualify for Section 6(2).
Wanted to share as the above might be your case also when you encounter the form/checklist.
PS you will have to fulfil all Section 6(1) requirements.
