If you trip some anti-money-laundering check, banks are legally required to freeze the account, often to close it, and must NOT tell you why. You cannot sue someone for doing something they're legally required to do. Well you can, but you will lose immediately... For what it is worth, I think a lot of AML is bullshit. But that doesn't change the fact it is the law, and many people support it because they assume it only affects drug trafficer and terrorists and billionares engaged in questionable activities. I heard this week that when AML checks on cash came in, the limit was 10kUSD for a cash transaction to be reportable. That was in the 70s, so the equivalent now would be 70kUSD today. That's per year. But the limit has not changed, so expect to raise a red flag if you sell a nicer end car or your tenant asks to pay in cash...
