Clarkson Hill directors Ron Pritchard and Mike Robinson have loaned the business £588,000 to help it meet its regulatory capital requirements.
The national IFA says the subordinated loan agreements, approved by the FSA, are sufficient for the company to meet the capital rules.
Earlier this month, AIM-listed Clarkson warned it may not be able to continue as a going concern unless it received an injection of capital.
Share trading in the company had earlier been temporarily suspended after it failed to psubmit its annual accounts.
The group reported an operating loss of £105,000 for 2009, compared to a near-£650,000 loss the previous year.
It said it paid costs of £231,000 following an FSA review into its processes in the second half of last year, and contributed £105,000 towards the £80m FSCS interim levy covering the failures of investment firms including Keydata.
Additionally, it said in the two years from December 2007, the impact of decreased initial commission against the present increase in trail caused a £300,000 plunge in gross profits.
Clarkson Hill today says trading to date "remains in line with expectations", adding the company has "sufficient working capital for its current purposes".
