Pesach Questions

We have some chametz and some refrigerated products that are simply not kosh er for Pesach that our housekeeper could benefit from. We can give them to her on Friday morning before 10:30 am, but can she still keep them in our house after that time? 

If the chametz is owned entirely by the non-Jew, he or she could hypothetically bring it into the home. But this is not ideal, as there is a concern that the chametz will get mixed up with the Pesach food/utensils. I would not recommend storing chametz for the maid, even if it is technically owned by a non-Jew. MATN
