Which law limits the amount of an individual's income that can be garnished?

The Wage Garnishment Law is the correct answer because it specifically regulates how much of an individual's disposable income can be withheld or garnished to pay creditors. This law aims to protect employees from having their entire wages taken by debt collectors, ensuring that they still retain enough income to cover living expenses.

Under the Wage Garnishment Law, there are established limits based on a percentage of disposable earnings or a specific monetary amount, which protects a minimum level of income for the individual. This legal framework supports financial stability for workers while allowing creditors to recover debts owed.

The other options do not pertain to income garnishment. The Worker Adjustment and Retraining Notification Act focuses on advance notice requirements for employees about layoffs. The Walsh-Healey Public Contracts Act governs labor standards for federal contracts but does not address garnishment specifically. Lastly, the Unit-Price Contract Law relates to contracts in construction projects, which does not involve income garnishment at all.
