Nicola Whittaker, 35, narrowly avoided jail after admitting leading a lavish life with gun-running ex-partner Paul Wilson.
But prosecutors believe she benefited from Wilson’s ill gotten gains to the tune of £426,030 – cash they claim was splashed on a posh house, jewellery and a boob job.
They want the money back from the mum-of-one who contested their Proceeds of Crime Act application at Liverpool crown court on Wednesday.
Most of the cash is tied up in the couple’s £250,000 home in Liverpool Road, Ainsdale – now worth up to £1m.
Prosecutors also want £82,000 spent on jewellery and £5,000 they claimed Whittaker spent on cosmetic surgery.
Whittaker, of Coronation Drive, Crosby, denied the jewels were ever hers and said her dad, Ronald Whittaker, paid for her surgery after she split from Wilson in 2006.
She said although Wilson initially bought her a boob job, she needed a second operation in 2008 because he hit her and split her implant.
Whittaker previously admitted money laundering and eight counts of concealing criminal property.
Her 12-month sentence was suspended for two years after Judge James Roberts accepted she had endured “extreme violence”.
She was given 300 hours unpaid work after the judge accepted she tried – but failed – to leave Wilson several times.
Prosecutors said the £30,000 deposit on the couple’s home and the £1,400 monthly mortgage payments from her bank account came from Wilson.
