Court filings by Nelson Bunker Hunt and William Herbert Hunt - heirs to the fortunes of the late billionaire H.L. Hunt - and their wives show a combined worth of at least $288.7 million.

The filings in connection with their bankruptcy cases show the the Hunts have combined debts of $2.14 billion, more than seven times their worth. But their current worth does not include assets whose value was listed as "unknown" in the documents.The figures, which provided the most detailed look yet into the personal wealth of the scions of the legendary Texas oilman, were disclosed in a list of assets and liabilities filed late Monday in U.S. Bankruptcy Court in Dallas.
