Houston Chronicle: “The heir to an oil fortune is powerless as lawyers, trustees, judges and guardians determine his fate.  For more than four decades, multimillionaire oil heir Ugo di Portanova has been all but powerless over his vast fortune.   His three Mercedes-Benzes, his chartered plane trips, his yacht excursions and the rest of his spending are all controlled by a small militia of Harris County probate court guardians, financial trustees, lawyers and judges.  Despite $65 million-plus in assets, di Portanova — described as one of the world's wealthiest ‘partially incapacitated' men — controls a single credit card that maxes out at $1,000 a month.”
