My husband has legal entanglement with another Jewish man. He has hired legions of attorneys to collect money on a judgment we could not possibly pay. Our net worth is less than two and a half million, his six hundred million and the judgment is five and a half million. His legions send messengers habitually on the Sabbath. We have asked politely to please refrain from this practice. Still the legions persist. Can another Jewish person disrupt a Jewish Family’s Sabbath?
Answer:
It is forbidden for him to send demand for payment, in any form or via any messenger, on Shabbos. The Shabbos is precisely for rest from such matters, and as a Jew, he should be wary of profaning the Shabbos in this manner.
Of course, this does not have bearing on the actual content of the dispute.
Sources: This practice is included in the prohibition of daber davar, meaning that one’s speech on Shabbos should be distinct from one’s weekday speech.
