1) Do I need to submit ALL passports since birth or up to last 10 years of travel?
I believe from the other threads the answer is "yes" and any you don't have should be justified as lost/misplaced? (would we need proof of this?)
Yes, the online form will ask her to list all previous passports held, and it will also ask where those passports are now.
She needs to include all passports she still has, but if any have been lost or stolen, she just states this on the application. No need to prove anything.
2) Should we include the application we made for the marriage visa? or copy of marriage visa page on passport?
No, but you can mention that you applied for one in your sponsor letter when you talk about your relationship.
Note:
She did NOT have a marriage visa, she had a marriage VISITOR visa. They are two completely different things. A Marriage Visitor Visa is one that allows marriage as a visitor and costs about £90. A Marriage Visa is a fiancé visa and costs £1,523.
3) How many joint travels do we need to include and would itineraries be suitable? (we'll dig up what we can over the last 7 years)
As many as possible. The more time you can prove you have spent together in person, the stronger your application.
Ideally you should send the actual boarding passes, but if you no longer have them, the e-ticket can be sent instead.
4) Any documents which MUST be notorized? (including photos of relationship etc?)
Only documents where you cannot provide the originals, such as bank statements and payslips. Photos do not need to be notarised. If you like, you can get your passport photo page certified at a Post Office for about £10.
5) How far back should we include our correspondence when not together?
All the way back. You must provide evidence of correspondence for the entire length of the relationship.
If you have been together since Dec 2010, I would probably include maybe 6-10 messages/emails/calls per year.
