Question:
What should an owner of non-kosher nursing homes do on Pesach – the homes will be serving chametz, as they do all year round. Does a typical ‘shtar mechira’ (as some use for Shabbat) allow attributing the ownership of the chametz to the partner?
Answer:
Yes, the best arrangement will be to sell the nursing home for the duration of Pesach to a partner, so that the owner will not have any share of the chametz.
This is presumably similar to the shtar you mention, though I do not know the details of this shtar.
Please post another question in more detail if this is required.
Best wishes.
