Why sanctions screening can't wait

Unlike much of the AML framework, sanctions obligations are absolute: you may not do business with a listed person or entity, regardless of intent or risk appetite. They apply to every business, and breaches carry serious penalties.

The hard part is that lists change constantly and the official EU list can lag the underlying legal designation by days. Screening once at onboarding is not enough — you must re-screen when the lists move.

The defensible approach is continuous: re-check your client base against each list update, screen on every change, and keep dated proof of each check. That evidence is what demonstrates you met the duty even when the answer was 'no match'.
