Paul McCartney and Heather Mills returned to court Monday in an attempt to agree on terms for their divorce. The fight over the wealth of the former Beatle, who is estimated to have as much as $1.6 billion, could produce Britain's largest-ever divorce settlement. The hearing before Justice Hugh Bennett is scheduled to last five days. The terms of any settlement would not become public record unless it moved to the Court of Appeal, or either of the parties chooses to reveal details. Press reports have suggested that McCartney has offered his wife around $50 million, and that she is seeking at least double that amount. "Current estimates suggest that Heather is likely to receive anything from 50 million to 100 million pounds ($100-200 million) as her final settlement," said Suzanne Kingston, a family law expert.
