Does divorce occur if the wife goes to her daughter's house after her husband swore an oath of divorce upon her not to go to the groom's house and his father's house due to the father's ill-treatment of his wife, and then the groom's father apologized for the ill-treatment?

Do not break your oath regarding your wife entering her in-laws' house after the reason for which you swore has ceased to exist. This is because a ruling ceases to apply when its underlying cause is removed. We advise you to avoid suspending divorce and swearing by it with the intention of threatening.
