A trial into the validity of the couple’s prenuptial agreement was to start Monday morning. But midafternoon, the court said the two sides were attempting to reach a settlement. The trial has been postponed until Wednesday morning to give them time to work out their differences. Money manager Dias Griffin was initially expected to testify Tuesday. Court proceedings had been scheduled to last seven days over the prenuptial agreement alone. The couple is also fighting over child support and custody of their three children. Monday’s last-minute negotiations didn’t come as a surprise to experts, who say prenuptial agreements and privacy concerns mean few divorces among the wealthy get this far.
