Corporate partner Jucker rejoins DJ Freeman in its media and communications department in January after two years at Sonnenschein.
Jonathan Lewis, chief executive at DJ Freeman, says: "We were very sorry to see Antoinette go then, but she had an opportunity she wanted to pursue.
"When we heard what had happened to Sonnenschein I was getting numerous calls from partners saying 'Are we going to get Antoinette back?'
"She has a fresh experience and it's very hard to come across quality lawyers of her calibre, especially to help build our media side which we are investing in at the moment."
Lewis adds that Jucker is the second partner to rejoin the firm in just over a year. Terry Green returned with the property finance team that moved from Stones Porter in October 1998
