Ehsan Qureshi, a correspondent with the state-run Associated Press of Pakistan, said Tuesday that footage of him talking to Woolmer was used by the British broadcaster in a defamatory manner.
The segment, part of a Panorama programme called "Death at the World Cup," showed Qureshi in conversation with Woolmer at a social event during the two days before the coach died, he said.
Qureshi's lawyers, in a legal notice they said was served to the BBC, said the programme "gave an impression as if me and the other gentleman accompanying him were the suspects or had anything to do with the death of Bob Woolmer."
But a BBC spokesman said it was "preposterous to suggest that anything in this Panorama programme is defamatory of Mr Qureshi or has damaged his reputation in any way at all."
"Any legal action will be vigorously defended by the BBC."
Woolmer was found dead in his hotel room in Jamaica the morning after Pakistan crashed out of the tournament. Police said in March they believed he was murdered.
Qureshi's lawyer claimed the programme "was an attempt to malign my client to connect him with an offence to which he had no concern at all," according to the writ seen by AFP on Tuesday.
He said the programme was screened on the international BBC World channel, and clips were re-broadcast on Pakistani and Indian networks. Qureshi said the footage caused him and his family distress.
No suspects have been arrested over Woolmer's death, which recent reports suggest may have been from natural causes.
