The ruling on swearing an oath regarding one's wife by delegating her affairs to herself

Question:
He says: I swore an oath while I was angry at my wife and told her, “If you go to that place, you are in your own custody.” What is the ruling on that?

Answer:
The questioner: Where is he? Which country? If he is here in the Kingdom, he goes to the Sharia court and asks the judge, or he comes to the Ifta' Center and asks, and they look at his question, go into detail with him, record his statement, and he signs it. What is the issue? But in any case, it requires procedures. Either he goes to the court near him, or if he is close to the Ifta' Center, he goes to the Ifta' Center in the region. In Riyadh, may Allah make his affair easy, if Allah wills. And if he is outside the Kingdom, he goes to the scholars in his country or to those to whom Ifta' has been delegated. He goes to the Ifta' Centers in his country. Yes.
