When does a revocable divorce become final?

A revocable divorce becomes final—in the sense that all marital relations are severed and reciprocal rights and duties such as financial support and a wife's obedience to her husband, inheritance and so forth are no longer applicable—when the wife's 'idda [postmarital waiting period] ends. The 'idda ends upon any of the following:
For a menopausal woman, when three months pass after the divorce.
For a pregnant woman, after giving birth.
For a woman who experiences menstruation, after three menstrual cycles according to a number of scholars or after three intervals of purity between menstruations according to others.
Allah the Almighty knows best.
