If a man swears an conditional oath of divorce upon his wife, and the condition is met, and he pays an expiation for the oath, does that count as a divorce upon the wife?

If the husband, who is capable of examining the evidence, or has been given a fatwa by trustworthy scholars, concludes that the one who took an oath is obliged to pay expiation without the occurrence of divorce, then there is no blame upon him. When there is a dispute regarding matters of divorce, it is best to refer to the Sharia court, as a judge's ruling resolves disagreements.
