Does divorce occur if one swears by it to keep his father from knowing what transpired between the son and his uncles, knowing that the one who swore has already solemnized his marriage but has not yet consummated it with his wife?

If the marriage contract has been concluded, then divorce takes effect. If you conditioned the divorce on informing your father about what transpired between you and your paternal uncles, which would spoil affection and sow animosity, then according to the majority of scholars, divorce takes effect if you inform your father of that. The only way out to avoid divorce is not to convey these words to your father. You must be cautious in the future about swearing by divorce.
