I think to be on the safe side, I would do separate checks. You did not indicate if the couple is married, but by completing two checks, you have covered yourself. Also,you can give away $15,000 to as many individuals as you’d like. A husband and wife can each make $15,000 gifts, to one person. So, a couple could make $15,000 gifts to each of their four grandchildren, for a total of $120,000.
