If you did not own the home, then you do not owe U.S. income tax on the property. If you were a part-owner, then you have to report your share of the gain. However, on your father's death, your basis equalled the date of death fair market value of the property, so there may not have been much gain for U.S. tax purposes. If there was interest earned on a C.D. of which you were a one-third owner, then you owe U.S. income tax on that one-third. The documentation you need for the home is the escrow from the sale. The documentation you need for the C.D. is the interest statement. Please hire a competent CPA in Jacksonville.
In general, whatever gain occurs on assets you own and sell are taxable. And whatever interest your receive is also reportable. In this case, you may be a 1/3 owner in the property and the CD and would be taxed accordingly. But this is a gross oversimplification of the issue. When assets are cross borders, the applicable concepts get even less simple. You really should consult with one of the international tax attorneys for details.
