More than £40,000 of drug money has been seized by police.
It comes following the conviction of Vietnamese national Duc Sy Bui, who ran an illegal business through a nail bar in Lincoln.
Bui, 42, of Blyton Grove in the city, was found guilty of two charges of acquiring, using or possessing criminal property and one charge of money laundering.
He was jailed for four years.
Lincolnshire Police searched Bui's home in Blyton Grove, Lincoln, in March and August 2010 where they found: £41,118, 140 Euros, $106, 55,000 Vietnamese Dong and 500 Hungarian Forints.
Of the total cash seized, £10,000 of it was found in a woman's handbag, a further £17,000 in a child's bedroom and £1,490 in the loft.
The remainder of the cash was found around the house.
Following his conviction an application to confiscate criminal benefits was initiated.
Separate to the criminal investigation, a civil procedure also began into the ownership of the cash found at the addresses.
Police say people were distancing themselves from the cash and nobody claimed ownership.
Therefore on Wednesday August 29, 2012, at Lincoln Magistrates Court, an investigator from the Economic Crime Unit successfully gained the forfeiture of the cash as being either from criminality or for the future use of crime.
Detective Sergeant Ian Jarman, head of Lincolnshire Police Economic Crime Unit, said: "Lincolnshire Police will use the Proceeds of Crime Act 2002 to aggressively tackle criminality in the county of Lincolnshire and to ensure that criminals do not benefit from crime."
