body: Say someone applies for a loan and they get the loan. Afterwards the lender wants to see proof of income, but the lendee denies and refuses to provide any proof after the fact. Given that it's after and not before, is there any difference in legal routes? If one refuses to provide proof of income before receiving any money, it's obvious that the lender can just not give it and not care -- but what about after the loan was given? Can they legally demand you provide proof after they give money?
  
  
  Are you required by law to do so then? If you refuse, would they cancel your account and make this a civil/term based account termination -- or is this actually an entire criminal suit to unfold?
  
  
  Because it's very easy to say no and avoid giving proof, but saying no isn't proof of being guilty yet.
  
  
  Realistically, how far could this turn serious if the lender demanded and the lendee refused?
