Garnishee order
From ACT Wiki
A court order that directs a person or entity who holds funds or assets for a debtor to withhold them from the debtor and release them to the debtor's creditor in order to pay off the debt.
For example, an order from a court forbidding a bank to release money that it holds in the account of one party for as long as that party owes money to a second party.
The second party obtains the garnishee order and the bank is the garnishee.
