In practice, an
earnings arrestment is a Scottish enforcement method (diligence) by which a
creditor recovers a judgment debt from a
debtor’s wages: once the
employer is served, they must deduct a statutory amount from the debtor’s net pay and remit it to the creditor until the debt and expenses are cleared. The procedure is governed by the Debtors (Scotland) Act 1987 (as amended), with deduction bands and protected minimum earnings set by regulations. It applies to earnings from employment (not self‑employment). Breach of duty can expose the employer to liability for unpaid sums.
Related Scottish mechanisms include a current maintenance arrestment (for maintenance/aliment) and a conjoined arrestment order where multiple arrestments exist. Service is typically effected by sheriff officers after decree or document of debt and charge for payment.
The term is specific to Scotland. The broadly equivalent process elsewhere is an attachment of earnings order: in England and Wales under the Attachment of Earnings Act 1971, in Northern Ireland under the Judgments Enforcement (Northern Ireland) Order 1981, and in Ireland under statute (commonly for maintenance). Practitioners also refer to this as wage arrestment or diligence against earnings.
