Garnishment refers to a court ordered process for collecting on a judgment, which takes money directly from the defendant’s wages or other third party who owes the defendant a debt. A garnishment order instructs a third-party who owes money to the defendant, typically the defendant’s employer or the defendant’s bank, to pay some or all of that money to the plaintiff instead of the defendant.

A garnishment is an order directing a third party to seize assets, usually wages from employment or money in a bank account, to settle an unpaid debt. (Investopedia)
