The claim that a divorce occurred leads to stopping the proceeding of the separation lawsuit procedures, at which point the evidence is sought to prove the divorce occurrence and its type is irrevocable or revocable, so if it is proven that divorce is irrevocable then there is no benefit in considering the separation lawsuit.
It is worth noting that divorce can be confirmed by the testimony of someone who has heard from the husband at the moment of the divorce, or if the husband tells him about it. As for the proof of divorce by listening, even from the wife and the people, it is not counted.
