Relatives of the deceased want 30-50 million yuan (4.9-8.2 million dollars), said Li Xiaolin, a lawyer who is a confidant of the family of deposed politician Bo Xilai.
Bo's wife Gu Kailai was handed a suspended death sentence in August 2012 after she was convicted of murdering her friend Heywood in the south-western region of Chongqing that was ruled by Bo.
Bo, once a rising, populist regional leader of the ruling Communist Party, was removed from power and expelled from the party last year.
He is due to stand trial soon for corruption. The 64-year-old faces a sentence of up to life imprisonment if convicted.
China has charged disgraced former senior politician Bo Xilai with bribery, abuse of power and corruption, state news agency Xinhua said on Thursday, paving the way for his trial.
Prosecutors in the eastern city of Jinan in Shandong province indicted Bo on the charges on Thursday, Xinhua said.
Bo took advantage of his position to seek profits for others and accepted an "extremely large amount" of money and property, the indictment was quoted as saying.
The deposed Communist Party leader in Chongqing municipality also embezzled public money, the document said.
Legal sources in Beijing said on Wednesday that his trial was expected to start in the coming weeks.
If convicted, he could face a prison sentence of at least 15 years.
Bo's wife, Gu Kailai, and his former police chief, Wang Lijun, have both been jailed over the scandal stemming from the murder of British businessman Neil Heywood.
The government in September last year accused Bo of corruption and of bending the law to hush up that murder.
The trial of ousted Chinese politician Bo Xilai, originally slated for today is not likely to begin until after annual political meetings in March, a state-run newspaper reported on Monday, citing court officials in Beijing.
Bo, 63, was a charismatic but divisive leader who some had tipped for a spot on the country's highest political body in last year's leadership transition.
But he endured a spectacular fall after his former police chief Wang Lijun fled to a US consulate last February claiming Bo's wife Gu Kailai had poisoned a British businessman. She was later handed a suspended death sentence for the murder of Neil Heywood.
On late October prosecutors launched a corruption investigation of Bo Xilai himself.
The trial of China’s former Politburo member Bo Xilai has been scheduled for January 28, Dagun Bao online newspaper reported on Friday.
The disgraced politician is facing charges of trying to cover up the murder of a British businessman by his wife.
In August of last year Gu Kailai was handed a suspended death sentence and in October the authorities brought corruption charges against Bo Xilai himself.
