Is there any experience about the contracts used to lease the specific rooms of a house or furniture with chometz that would indicate whether it would be allowed to enter if one found another food item or needed to check something there?
When I asked the question of my Rav, he answered that part of the agreement with the non-Jew was that I could have access to the areas rented out to the non-Jew on Pesach. The access should be for as short a time as possible.
Aish.com poses the question:
- During Pesach, may items be taken from sections of the house that have been sold?
The contract gives permission to the seller to retrieve an item from these locations in times of need. However, one should not do so too often, since this would indicate that the sale has not been taken seriously.
It is possible that a specific contract will not allow for the seller to retrieve an item from a location in time of need. Therefore, it is necessary to check the contract first.
There was an answer that if you find Chametz in your house, it can be put into the closet that had been rented (not sold) to the non-Jew for his chametz because the chametz belongs to him and should be put there. This was part of a discussion about destroying Chametz that had been found during Pesach (especially on Shabbat or Yom Tov).
