Since it is prohibited to possess chometz on Pesach, any chometz left undisposed must be sold to a non-Jew. [Any chometz remaining in the possession of a Jew during Pesach may not be used, eaten, bought or sold even after Pesach.]
Therefore, all chometz that will not be eaten or burned before Pesach and all chometz utensils that will not be thoroughly cleaned by then should be stored away. The storage area should be locked or taped shut to be leased to the non-Jew at the time of the chometz sale.
Since there are many legal intricacies in this sale, only a competent rabbi should be entrusted with its execution. The rabbi acts as our agent both to sell the chometz to the non-Jew on the morning before Pesach starts and to buy it back the evening after Pesach ends.
The normally preferred practice is to conduct the authorization transaction in writing with the Rabbi, However, if you are unable to come over, online authorizations are acceptable for the purpose of selling chometz.
