Dual Control
Dual control requires two separate, independent parties to both take action before a consequential operation completes — one person initiating and a different person approving, for instance — so that no single individual can carry out the action alone. This is a close relative of separation of duties, applied specifically to the moment of executing a single high-stakes action rather than to splitting up a broader process.
Its protective value depends on the two parties genuinely being independent — if the same person effectively controls both approvals, through a shared account or an informal arrangement where one always rubber-stamps the other, dual control provides the appearance of a check without the substance of one.
