Ask the Rabbi

STAR-K CERTIFICATIONrealizes that there is no substitute for a person's own Rav. However, in today's busy and connected world many people have difficulty getting in touch with their Rabbanim when they are needed. In an effort to offer a solution to this challenge, STAR-K launched its Institute of Halachah as a public service. Over the years, the agency's Kashrus Hotline has answered more and more halachic questions beyond the scope of Kashrus information, from consumers the world over, beyond the standard steady stream of inquiries regarding the kosher status of foods and certified Sabbath mode appliances which has made the STAR-K Kosher Hotline famous. The formation of a separate official division within STAR-K testifies to the need for addressing these issues.

The Institute of Halachah is directed by HaRav Mordechai Frankel, under the guidance of HaRav Moshe Heinemann, STAR-K's Rabbinic Administrator. It is an invaluable resource for a diverse array of rabbis to discuss general halachic matters, as well as gain access to source materials for shiurim and answers to congregants' questions.

Shailos may emailed using the form below, or called into the Institute of Halacha at 410-484-4110 x238. Rabbi Frankel or on occasion another STAR-K Rabbi will respond to your email or return your call if you leave a message and phone number.

  • Halacha Questions

  • If a person wants to give money to someone else and be repaid with interest, the two of them need to jointly write and sign a heter iska. If the two people who want to write a heter iska are in two different cities, how is it done?
  • Halacha Questions

  • In Yoreh Deah (siman 118:9) we see that all simanim should not be left in the hand of a non-Jew. How then do hashgachos rely on non-Jews to print their siman on the wrappers? A similar question: Where do we find that a siman printed by a non-Jew is a siman at all? It is true that an eid echad is sufficient to verify that a product is kosher, but a non-Jew is halachically not considered an eid echad. Shouldn’t any product which has a kashrus concern need a halachically valid eid echad?

  • I recently got into an argument with my wife, and during the argument I said "I swear on my children's lives that I did not do such and such" .... I am almost 100% positive I did not do what I swore about - but I am uncomfortable about the statement and swearing that I did. How can I annul this or fix this?
