The Economic and Financial Crimes Commission (EFCC) said in a statement that High Court Judge Mobolaji Olajuwon issued the final forfeiture of the former minister's $3 million homes and cars in Abuja.
A court previously ordered the seizure of her upmarket property in the commercial capital Lagos and frozen funds that were said to be part of the rent collected from the property.
Alison-Madueke was a key figure in the administration of former President Goodluck Jonathan who served as petroleum minister from 2010 to 2015. She has been dogged by corruption allegations since she left office but denies the charges.
Alison-Madueke's whereabouts are unclear, but she was last known to be in Britain. She fled Nigeria shortly before Muhammadu Buhari's inauguration as Jonathan's successor.
In 2017, the U.S. Justice Department filed a civil complaint aimed at recovering about $144 million in assets allegedly obtained through bribes to the former minister.
