Hi Cass,
Have a read of the
bailiff powers from the Hobart Community Legal Centre:
"
The Powers of the Bailiff
The bailiff cannot forcibly enter the debtor’s house by, for example breaking a lock, but can enter if all he or she has to do is open an unlocked door. The debtor can refuse entry and is entitled to use reasonable force to stop the bailiff getting in. This only extends to the outer door of a dwelling house; once inside he may break open inner doors. Furthermore it gives no protection against forcible entry of a bailiff into other buildings on the debtor’s property that are not physically connected to the dwelling house (for example, a barn or garage), or other buildings such as a shop used only as a place of business.
The bailiff may also enter the house of a stranger to execute the warrant, but does so at his own risk. If the goods of the debtor are not there the bailiff is a trespasser and liable to an action. It seems the bailiff may also break in if the debtor’s goods were taken there to avoid a lawful execution.
Lawful and Unlawful Execution
It is important to remember that even if execution is made following an illegal entry, the validity of the execution is not affected. The debtor’s only remedy would lie in an action against the bailiff for trespass. Fortunately bailiffs rarely exceed their powers as they are reluctant to behave in a manner for which they would be personally liable.
After the bailiff has been let in and has seized goods, he can forcibly re-enter the second time to take them away. He may also, if necessary, break open a door in order to carry away goods that have been seized. "
If your ex wishes to prevent enforcement, he must either negotiate an arrangement with the judgment creditor, challenge the debt or order in court or apply for a stay (suspension) of enforcement action.
