It depends what sort of court judgement it is - if it's just a stock standard judgement debt arising from a contract then yes.
However, if its one of the following types of debts - it will not be "cleared" by bankruptcy:
- debts arising from court fines or breaching bonds
- debts incurred by means of fraud or fraudulent breach of trust
- child support/maintenance debts
- Centrelink overpayments incurred as a result of actual fraud
- an amount payable under a proceeds of crime law
And yes, after bankruptcy unsecured creditors (those who don't have any of your assets securing the debt - such as a house to a mortgage) cannot enforce a remedy against the bankrupt. They can't take fresh steps in proceedings wihtout permission of the court and any issuing of summons and garnishes must be halted.
