Q. If one already sold his chometz and then acquires more, I heard That Rav Miller rules that it is not included in the mechira. Is it enough just to contact the Rov it was sold to and tell him about the new chometz?
What happens when after the mechira, the children arrive and bring chometz?
A. Horav Shlomo Miller’s Shlit’a opinion is that it suffices to contact and inform the Rov.
If after the mechira, the children arrive and bring their chometz, they have to dispose of it themselves, or sell it to the Rov.
