Donna Shedden, 49, admitted taking £613,073 from the limousine firm where she worked - Charlton Chauffeur Drive, based in Govan, Glasgow - between March 2007 and February 2013.
During that time, in June 2008, she married Glasgow fiscal William James Mackay in Bermuda.
Last night the couple's detached sand-stone villa in Newton Mearns, East Renfrew-shire, stood empty with a "For Sale" sign in the garden. It is on the market for offers over £420,000.
Glasgow Sheriff Court was told Shedden, regarded as a "trusted member of staff", had worked with the chauffeur company since October 2003 and worked her way up from a part-time book keeper to financial manager.
She continued to transfer money elect-ronically into her own account even when the company hit hard times and was forced to make employees redundant and cut salaries.
Shedden, who earned £23,000 a year, was caught when a suspic-ious colleague invest-igated while she was on holiday in South Africa for a month at the start of this year.
When she returned from her holiday she was picked up by a limo from her firm and brought to the head-quarters. She was confronted by her boss about the money and admitted the offence.
Procurator fiscal depute Erin Campbell said: "Analysis of the accused's bank state-ment would indicate she had engaged in a lifestyle far in excess of what she ought to have been able to afford."
Shedden was using the cash for credit card and store card pay-ments as well as loans.
The court was told she spent the money on clothes, jewellery and social activities and was described as a "compulsive spender".
Sheriff John McCormick deferred sentence and told her: "In light of the sums embezzled here a substantial custodial sentence is almost inevitable and you should prepare yourself for that."
Proceeds of crime papers were served on Shedden for the Crown to confiscate cash from her.
