Exodus 12:19 "Seven days shall there be no leaven found in your houses"

We are forbidden to own any Chametz on Pesach.

Most people usually store all the Chametz foods, dishes and any other items which may be considered Chametz away and hidden from sight.

Then they go to the Rabbi and sign a note of sale.

The Rabbi sells the entire stock of Chametz to a non-Jew.

This enables us to keep this Mitzvah of not owning Chametz.

The non-Jew becomes the owner of all Chametz during Pesach, and then after Pesach the Rabbi buys back the Chametz from him so we can use it again.
