Milestones: SEEKING DIVORCE. Ivana Trump

SEEKING DIVORCE. Ivana Trump, 41, former Czechoslovakian fashion model and ski competitor; from struggling real estate developer Donald Trump, 44; after 13 years of marriage, three children. Though the couple separated spectacularly nine months ago, the formal decision to file papers was announced only last week. Ivana Trump is still challenging the couple's postnuptial agreement, which limits her claim to $10 million plus their $12 million estate in Connecticut.
