Time-share mogul David Seigel went to court this week to try to reduce the payments he owes his ex-wife Bettie for last year's $200 million divorce settlement. Claiming the court's estimate of his wealth and income was unduly influenced by a former employee who is now a competitor, Seigel says his company earned $70 million less than reported. "The facts represented by `former Chief Executive Officer Ron` Levanthal as set forth were either intentionally or negligently represented," the motion says. Levanthal and several other Seigel employees have formed their own venture, Tempus Resorts International, since last October's divorce. Seigel has until December to make his first divorce-settlement payment. Unless the judge agrees with him, Seigel must pay $12.5 million this year.
