Amir Azam, 43-years old, is currently serving a four-year sentence, after being convicted of drug offences earlier this year.
The National Crime Agency launched a civil recovery investigation against Azam, in a bid to recover the proceeds of his criminality.
At a hearing in September 2014, a Civil Recovery Order was granted against five of the seven homes in Isleworth, Hounslow, Chiswick, Greenford and Hillingdon, as well as money from five bank accounts located in the UK and Luxembourg.
The remaining properties – two homes in Southall and Hounslow – were given the go ahead to be recovered by the High Court on Thursday October 30.
The assets seized totalled approximately £3.3million.
Stephanie Jeavons, Deputy Director of the NCA's Economic Crime Command said: “Azam and his extended family were able to enjoy the fruits of his drug trafficking without interruption for many years.
“He thought he could get round the law by putting the homes in family members’ names. He was wrong.
“Rest assured, the National Crime Agency will continue to pursue and disrupt those that seek to benefit from assets derived from serious and organised crime."
