<prompt> Human: My in-laws are paranoid of keeping too much money in their bank account. Whenever it gets above 6,000, my father-in-law pulls out 5,000 in cash and puts it in his safe deposit box. They are generously gifting us money for our down payment on our first house, but it will be given to us in cash. How can I use that money for the down payment? Would it be as simple as showing his statements where he withdraws that amount of money? How difficult would it be if he refused to do that? Side-note: If anyone has any advice on convincing paranoid older people to let their money earn money, I wouldnt mind hearing it.  <response>: If they dont trust banks, why would they trust safety deposit boxes at banks? Also, could they name a single person who ever lost a cent of their money in a savings checking account in the United States?Statements would be fine, but at the end of the day, the giver is liable for all taxes and obligations in these situations.
