A court has heard that a billionaire allegedly spent years planning to “escape” his wife before their marriage ended. The dispute matters because his proposed divorce settlement of $633 million has reportedly angered his wife, highlighting the scale and acrimony of the financial proceedings.

The available account does not identify the couple or give further details of the court case. The central figure is the reported $633 million offer, which the wife is said to regard as inadequate or objectionable despite its size.
