Property management tax reporting - foreign property owner

[Lettie T.]

I just started managing a property owned jointly by a married couple. The husband is a U.S. citizen, the wife is not. They live in Australia full-time (not sure if that matters). How do I go about preparing tax forms? Do I need to have the wife fill out a W8 BEN? Do I omit the wife from the 1099-MISC? What else do I need to know about tax reporting in this situation?

Thanks in advance!
