TSEM6354 - Legal Background to Trusts and Estates: Trust ends because of fraud or bankruptcy
Fraud
A trust can be nullified, if it was made with a fraudulent intent. For example, a settlor may have set up a trust to stop a creditor recovering a debt.
Bankruptcy
Under the Bankruptcy Act a settlement may become voidable upon the subsequent bankruptcy of the settlor. Whether it is voided (wholly or partially) depends upon the circumstances.
