Q. I own a property in partnership with a company where one of their partners is Jewish but not observant. They prepared and signed a lease during last Shavuos. Can I co-sign this lease that was then prepared on Yom Tov and benefit from it? It is likely that the ones who prepared the lease were Non-Jewish office workers.

A. Even on Shabbos if someone performed intentionally a prohibited melocho it is only forbidden for that individual to derive benefit from it, but not for others. If a Gentile did the work, it is usually permitted after enough time went by to complete that melocho, after the end of Shabbos. (O.H. 318: 1 – 515) Therefore there is no reason not to sign and use that lease.
