Due to the complexity of my case, I do feel it best to keep most of what is deemed unnecessary as I've added in the additional info why I've added it, so that all my ducks are in a row. We are exempt, and I have all of the needed documents that you've stated. I do appreciate the heads up, but I have added a contents letter for them to reference as it's in order by what's in the stack.
Stamped biometrics confirmation sheet.
I'll explain a bit. I made an error on my father's birthday, so the only evidence I have of his correct birthday is my birth certificate. Council tax for proof that his Nan lives at the address. Photos with in law's is proof that my son has strong ties there, proving the move is in his best interest as he's not my husband's biological child. Mother in law's bank statements also have her address on them, proving she lives at the property. Also, any mother could claim to pay something to help their child, so I figure it's best to add proof lol.
I've wrapped it all in brown paper and tied a string around to close it so that everything stays in place, stays safe in the post, and looks nice.
