Does a divorce issued by a maternal uncle, contingent upon his being informed about his wife's actions, take effect?

To know the ruling on swearing by divorce and its consequences, your uncle should consult a scholar, because the intention of the swearer is taken into consideration. Breaking the oath of divorce occurs if you do not inform him that his wife's income is part of the matter, and even if no time was specified, breaking the oath is realized when there is despair of that happening. You erred by raising this matter with your uncle in an ambiguous way, so you must tell him that his wife has an income involved in the matter and make it easy for him to avoid problems between him and his wife.
