No, for three reasons. First, the annual gift tax exclusion in 2015 is $14,000. Second, the annual gift tax exclusion is by person, so the father-in-law is counted as giving 1/2 the gift to the husband and 1/2 to the wife (if the father-in-law is married then 1/2 the gift is treated as from his wife. So a married couple can give $56,000 to another married couple. Third, the gift tax is imposed on the donor not the recipient, so if there was a gift tax, the father-in-law would have to pay it. Not you.
