For the purposes of the Bankruptcy Act 1966 (BA 1966), a person is solvent if the person is able to pay all the person's debts, as and when they become due and payable (section 5(2), BA 1966).
Whether a company or an individual is solvent depends upon a factual assessment of the circumstances impacting the particular company or individual. A company or an individual that is not solvent is insolvent.
