Mishcon de Reya and Payne Hicks Beach are set to meet in court after Lady Heather McCartney instructed Mishcon consultant Anthony Julius to represent her in her divorce from former Beatle Sir Paul McCartney.
Sir Paul has picked Payne Hicks Beach partner Fiona Shackleton to fight Lady McCartney’s demands.
Shackleton and Julius were previously instructed for Prince Charles and Princess Diana respectively in their divorce proceedings in 1995.
The McCartneys announced their separation in June after four years of marriage. Lady McCartney is now fighting for a share of Sir Paul’s £825m fortune.
