Hi - I think the best thing to do is for you to get an immigration lawyer. The lawyer will sort out all documents needed. We hired a lawyer when I applied my fiancee visa last March 2014. The lawyer was based here in the UK. All documents were sent to me then to the Philippines. All I did was submit it according to the order of papers when I received it and just filled in the pages which were needing original copies. It took 3 months for the result but its all worth it. It's just quite expensive but we just thought of being safe than sorry. The process wasn't easy. Very tough nowadays .... Good luck!
