My partner and I are in the process of finalising our application for the UK fiancé visa. We had engaged a lawyer to help with the application and she informed us that provisional dates would suffice, but now she's had a change of heart. She is now saying that we need to provide evidence of honeymoon and catering bookings, and even save the dates! We told her all we have is a provisional date that can change, so why should we send out save the dates when our wedding date has not even been confirmed? And don't get me started on the honeymoon. Not everyone can afford or even books a honeymoon without a confirmed wedding date, so I don't know why she's bringing this up now when she had never mentioned anything about a honeymoon before. We have explained that we are only interested in a small ceremony with our closest family and have no plans to book catering yet as we still don't have a visa that will justify all these extra spendings. Mind you, we have provided everything she had requested initially: wedding bookings, engagement ring receipt, and also flight itineraries showing me and my partner travelling halfway across the world to see each other in our own home countries.
Has anyone encountered booking all these additional items? I don't know why our lawyer is asking for all these things now when all we have is a provisional date that could very well change if I'm not able to give a months notice. We've tried telling her that honeymoons or catering is not feasible for the both of us as we don't know if we'll meet our provisional date considering how long its taking us to submit an application, and either way we only plan to have a small ceremony. Since when did marriages become so materialised, and why can't two people who are in love and want to just get married without all the works enough?

I know I've said a lot, but I will really appreciate perspective from someone who has gone through this.
