Q: Our shul invited a noted Rabbi to speak. Can I record the shiur? Can I make copies of the recording?

A: One should ask permission before recording, even though it is usually permissible to record a public shiur. The speaker is aware that people often record shiurim, so there is tacit permission to record if the speaker did not stipulate otherwise. (A professional lecture could be different.)

Moreover, it may even be permissible to make copies of the recording. However, if the speaker plans to sell copies, or sells recordings of a similar shiur, it is prohibited to infringe on his rights.

When the speaker stipulates that he does not allow recording, then it is prohibited, even for personal use. If he stipulated so as one of the terms of his employment, it is prohibited to expect him to work against his will. The same applies if someone gave a shiur in his house or in a private hall. The speaker can insist that he is willing to allow entrance only to someone who will follow his stipulation of not recording (Emek Hamishpat, Zechuyos Yotzrim, intro. 13:1-13; ch. 36:19-21; Igros Moshe, O.C. 4:40[19]).
