As long as you are a U.S. Citizen, your spouse may gift to you (or bequest) an unlimited amount of money or property, because of the unlimited marital deduction.
There is no gift tax on a gift to a spouse, (as long as it does not represent "future interest). Here is reference, scroll to "gift tax" http://www.irs.gov/publications/p950/ar02.html#en_US_publink100099451
