US news anchor for ABC, Peter Jennings, who died of lung cancer in August, left an estate valued at more than $50m (£28.5m) in his will.
Peter Jennings was born in Canada
Jennings, 67, left most of the estate to his fourth wife and two grown-up children from a previous marriage.
The influential journalist signed the will in April - 16 days after revealing he had been diagnosed with lung cancer.
Jennings, who had hosted ABC's World News Tonight since 1983, died on 7 August in New York.
His widow, producer Kayce Freed, was left 50% of the "net marital estate" and also got their Central Park West apartment in New York.
Jennings' two children, Elizabeth, 25, and Christopher, 23 - both from his third marriage to author Kati Marton, which ended in divorce - will also get a share.
Assets valued at $1m (£570,000) were left to the Peter Jennings Foundation, a charity he founded in 1998 that gives money to fight homelessness, drug addiction and illiteracy.
Besides stock and property, Jennings' assets included ownership of a race horse, Channel's Gate and another horse, named Cabin Fever.
