Can someone please tell me what Regulation contains information about not having lotteries in the bank.
National Bank Act (12 USC 25a) prohibits lottery activities by national banks.
If a state bank check your state laws.
For IN look to IC 4-32-1-2. It says a licensed qualified organization may engage in a raffle. IC-4-32-6-20 defines a qualified organization. Banks do not come within the definition.
