The previously undisclosed sum emerged in a Companies House detailing the particulars of the sale to Hartley Pensions in October.
Greyfriars slumped into administration in the same month with the FCA revealing the firm had appointed Adam Stephens and Henry Shinners of Smith and Williamson LLP as joint administrators.
The firm sold its financial adviser business on 16 October to Insight Financial Associates Limited.
Companies House filing showed the advisory arm of Greyfriars was sold to Insight for £440,000 and completed on 16 October.
Greyfriars Asset Management was initially a wealth management business which also provided DFM services.
It ceased DFM business on 31 March at which point clients transferred their portfolios out to an alternative provider or else became advisory clients of Greyfriars.
