Answered by Shaykh Amjad Rasheed
If a man tell people that he has divorced his wife, but he hasn’t told her, is she divorced?
A condition for divorce is that the man articulate an expression from among the expressions of divorce, or an expression that indicates divorce with the intention of divorce. A woman is divorced by this, even if she does not know it. It is not a condition of divorce that the wife know about it.
