This was part of the posting that is relevant to your question....mine was just a rough summary of some of the key things that wern't and were submitted.
Observations...some of the things that we did and didnt submit...rough summary:
a] Only submitted ordinary photocopy of my passport but submitted my original copy of my bith certificate - evidently this is perfectly okay as an alternative.
b] Didnt submit P60 but did submit 7 months payslips and 6 months bank statements (both current and savings account) plus letter from employer.
c] Submitted a lot of receipts for various costs in Phils....wedding cake...wedding ceremony. wedding reception receipts..internal flights aswell as flights to and from Phils.....hotel receipts etc etc and moneygram receipts
d] Samples of emails, Yahoo Messenger (one per week) and Skype logs and 1 recent itemised phone log / bill
e] 46 photos of myself and wife together with and without her friends and relatives spanning two visits to Phils
f] A 2 page summary of our time together, places we visited etc. (Sponsors letter - I made this a good one to ensure that the ECO could see that our relationship and marriage was genuine)
g] Landlord Letter and tenancy agreement
h] Things we didnt submit included my cv, my degree certificate, her degree certificate, notarised copy of my passport.
There are a few things missing from my list as the intention was to highlight some of the key points. We didn't submit any cards of any kind.
Because I had found out about the need to keep receipts, when I went to the Philippines in April and June I kept receipts for absolutely everything, including flight ticket stubbs for both of us, hotel receipts, wedding reception and cake receipts, UK Embassy receipts for local CNI etc etc and submitted them as part of the application.
Everything we submitted was original, apart from the unnotarised copy of my passport and some notarised / authenticated copies of bank statements.
We also submitted the ELT Annexe form, which rarely gets a mention on here, which makes me wonder if it is crucial or not. But in truth it is such a simple form that it is no problem to fill it out and submit it. It seems to be an afterthought type form that has been designed as a "bolt on" to the main online application form since the advent of the ELT requirement - hence the term annexe in its title. It is also quite possible that it is no longer a requirement ....
