I knew my Girlfriend for 8 months before I visited her the first time, and when I went I took all the evidence with me up to that point. Then when I returned I stated collected more evidence, which I will take with me next time I go there. that way each section is documented and I don't have to carry loads of paperwork with me. Also she has all the evidence we collected up to then in her posession, which makes sense as she will be needing it when she alpplies for the Visa.
