Selling Chametz

From Halachipedia

Selling Chametz

  1. When selling Chametz one should write down one’s address, and provide access to get in by leaving the keys by the Rabbi, neighbors, or security guard. If one feels uncomfortable doing that one should at least write down one’s cell phone number at which one would be reachable over Pesach. [1]

Chametz which is sold

  1. Chametz which one sells to a non-Jew for Pesach should be put away in a closet or another partition of 10 Tefachim and not opened on Pesach. Similarly one shouldn’t leave sold Chametz out in the refrigerator but rather it should be partitioned off with a wall of ten Tefachim. [2]

Stocks of companies which own Chametz

  1. Some authorities hold that there's is no prohibition of owning Chametz to a shareholder of a compnay which owns Chametz on Pesach who has no say in the actions of the company, while others hold that one should sell the shares together with one's other Mechirat Chametz through the Rabbi. [3]
