Definitions for "Arrestment"
The arrest of a person, or the seizure of his effects; esp., a process by which money or movables in the possession of a third party are attached.
This means that money or goods held by a third party are 'frozen'. The most common example is arrestment of funds in your bank account. The third party (eg a bank) may agree to hand the property (funds) over to a creditor.
This forces the debtor's employer to make deductions from the debtor's earnings and pay them to the creditor.
