In general terms the Bankruptcy Act 1966 :
The legal system provides a variety of means by which a creditor can enforce judgement. This includes the securing of the assistance of the Sheriff in seizing objects in which the judgement debtor has an interest and selling them in order to satisfy the judgement. The sale is conducted under what is known as a writ of fieri facias. If the debt is over a certain prescribed amount, the Sheriff may levy and sell the right, title and interest in a debtor's property.
The DSH Act is the only legislation that overrides the operation of a judgement order.
