A settlement has been reached over the estate of a man shot dead outside his Surrey home in 2004.
Mr Blackett was shot on his doorstep in September 2004
Daniel Blackett, 36, was shot by an unknown assailant in Thorpe Green near Virginia Water.
The Assets Recovery Agency (ARA) reached a settlement of a minimum value of £660,000 for Mr Blackett, who had convictions for theft and burglary.
It said a financial investigation showed he set up offshore companies under false names to hide his assets.
The ARA said the financial structures had been set up to hide the beneficial ownership of the Surrey home.
The ARA's settlement was made with the cooperation of Mr Blackett's partner, Nichola Jackson.
ARA deputy director of operations Charlie Dickin said: "The agency has a duty to help reduce crime and we aim to maximise the impact on those who make a profit from crime.
"In settlement cases, we proactively encourage respondents to settle at an appropriately high level. In this case, the forthright co-operation of Nichola Jackson has resulted in the early recovery of the late Mr Blackett's assets.
"Cases that are settled in this way are often in the interests of the respondent and their family, as well as in the public interest."
Mr Blackett's murder has not been solved, and police say it may be linked to his business dealings in the UK or overseas. He regularly visited Spain.
Mr Blackett's family - including his 11-year-old son and baby daughter - was in the house at the time of the murder, along with his mother and grandmother.
