Is the husband's statement to his wife: "Upon me be divorce, you are divorced" considered an oath of divorce where his intention is referred to, whether it be threat or divorce, or does it confirm the divorce?

The husband's utterance "You are divorced" is an explicit, immediate, and confirmed divorce by oath, "By divorce upon me"; thus, it takes effect without need for intention. An explicit (declaration of divorce) does not require intention; rather, it takes effect without a specific purpose. So, whenever he says: "You are divorced," or "Divorced," or "I have divorced you," it takes effect without disagreement.
