question about the proves

[Boky Jugger]

Alright, so me and my wife, live together, and know almost everything about each other.
The problem is my interview is coming in exactly 4 weeks.. And i cant get a lot of proves except pictures.. Like mutual phone, car insurance is on her mom, her sister commited a fraud in a bank on her name, so we cant open account either etc..
Anyone had problems for lack of documentations? What are ur suggestions guys/.
