He was 89.
His daughter, Julie Scott-Bayfield, said her father died in his sleep Friday at his home in Great Hallingbury, Essex, after a brief ailment.
The BBC said Carter-Ruck was renowned for his legal battles with the satirical magazine Private Eye and various national newspapers on behalf of celebrities.
In 1982 Carter-Rucket set up Peter Carter-Ruck and Partners before retiring in 1996, although he remained a partner.
Andrew Stephenson, senior partner at Carter-Ruck, paid tribute to him as a man of "great charm" with a dry sense of humor who was devoted to his family and his work.
Said Stephenson: "He always set the highest standards in terms of the service he gave to clients. It really was an outstanding example of how to conduct litigation."
