Is a divorce revocable or irrevocable if the wife waives her rights before the divorce, and does the ruling differ if the divorce is based on this waiver?

The default status of divorce is revocable, and the divorced woman has rights like all women who are revocably divorced, unless the spouses agree to a divorce in exchange for absolution; in which case the divorce becomes irrevocable. If the wife has absolved her husband of her rights in exchange for the divorce, or if there was a prior agreement to that effect, then the divorce is irrevocable. However, if the absolution is unrelated to the divorce, and he then divorces her, the divorce is revocable. In case of dispute, it is advisable to resort to the judiciary or reliable scholars.
