Each one of us may be called upon to divulge information about an individual or a family in regard to a shidduch. Furthermore parents who are looking for a shidduch for their children are pro-actively making calls regarding prospective shidduchim. They are searching for information, character analysis, health information, etc., much of which will help them make up their minds whether or not to pursue a certain shidduch. With this in mind, we must all be aware of the enormous responsibility of what we say in response to these questions. Our words can literally make or break a shidduch. Therefore, it is obligatory for us to become acquainted with the halachah of what we can and cannot say. Sometimes people speak when they should be quiet and sometimes they hold back when they should speak up. It is imperative to know when we must convey information and how it is to be conveyed.
