Payne Hicks Beach could find its client Sir Paul McCartney cross-examined by estranged wife Heather Mills as the divorce case goes to court today (11 February).
Mills decided to act for herself at the High Court private hearing after falling out with her lawyers Mischon de Reya. She reportedly owed her former lawyers an estimated £2m in legal fees.
Previous attempts at a divorce settlement foundered as Mills refused to be bound by confidentiality clauses preventing her from writing or talking about the couple's four-year marriage.
McCartney reportedly offered Mills a lump sum of around £20m, as well as an annual payment of some £2.5m until the couple's daughter, Beatrice, reaches 18. But this offer was only on the table in exchange for a confidentiality clause.
Mr Justice Bennett is hearing the robed case at the Royal Court of Justice.
McCartney is being represented by Nicholas Mostyn QC of One Hare Court who was instructed by Payne Hicks Beach partner Fiona Shackleton.
