They said a memorial service for t he actor and director, who died on Sunday aged 90, was being planned for " later this year" with details to " be announced accordingly".
A spokeswoman for the family said: " Lord Attenborough's funeral will be a strictly private family funeral.
"The family have asked for no flowers but, if people wish, charitable donations can be made to Denville Hall, the care home where Lord Attenborough spent his final years."
He moved to the rest home for retired actors, in Northwood, north-west London, in 2008 and his widow still lives there.
News of his death sparked tributes from p oliticians, Hollywood stars and industry leaders.

Career highlights included Brighton Rock, where he played the psychopathic criminal Pinkie, the 1993 blockbuster Jurassic Park and Gandhi which he directed and which won eight Oscars including the best director award.
Jurassic Park director Steven Spielberg said: ''Dickie Attenborough was passionate about everything in his life - family, friends, country and career.
''He made a gift to the world with his emotional epic Gandhi and he was the perfect ringmaster to bring the dinosaurs back to life as John Hammond in Jurassic Park."
Star of Gandhi Sir Ben Kingsley said he had grown to love the director, who had worked tirelessly to bring the Indian leader's story to the big screen.
''He placed in me an absolute trust and in turn I placed an absolute trust in him and grew to love him,'' said Sir Ben.
''I along with millions of others whom he touched through his life and work will miss him dearly.''
Prime Minister David Cameron was among the first to pay tribute to Lord Attenborough.
"His acting in Brighton Rock was brilliant, his directing of Gandhi was stunning - Richard Attenborough was one of the greats of cinema," he said.
Labour leader Ed Miliband said: "The death of Richard Attenborough is a sad day for the film world and the Labour movement. He and his work will be remembered."
