The spokesman for Benazir's Pakistan People's Party, Nazir Dhoki, said on Thursday: "Benazir Bhutto filed the appeal in a Swiss court of police magistrates on Wednesday."
A date for hearing the appeal has yet to be fixed.
The appeal was drafted by Bhutto's lawyer Farooq Naik who is already in Geneva and working with a Swiss lawyer.
Dhoki said Bhutto, who ruled Pakistan twice from 1988 to 1990 and 1993 to 1996, would summon Pakistani generals for cross-examination.
However, he did not name the generals.
Swiss magistrate Daniel Devaud found Bhutto, her spouse Asif Ali Zardari and their Swiss intermediary guilty of money laundering on July 30.
Zardari is currently serving a
prison sentence in Pakistan
He said they obtained almost 12 million dollars in illegal commissions from two Swiss firms for a 1994 customs inspection contract.
Devaud handed the former first couple a suspended jail sentence of six months and ordered them to return the money plus a diamond necklace to the Pakistani state.
The Swiss finding is considered a major embarrassment for the couple, who have rejected more than a dozen corruption allegations against them as politically motivated.
But Pakistani Information Minister Sheikh Rashid said the judgement vindicated President Pervez Musharraf's assertions that Bhutto was engaged in "looting and plundering" Pakistan.
