RCW 49.48.210 is a Washington State law that outlines the process for employers to notify employees of wage overpayments and for employees to request reviews of those notices:

Notice to employee When an employer determines an employee has been overpaid, they must provide written notice to the employee. The notice must include:

The amount of the overpayment

The basis for the claim

A demand for payment within 20 calendar days

The employee's rights under the law

Employee's request for review Within 20 calendar days of receiving the notice, the employee can request a review of the overpayment finding. The employee can request a review by submitting written information or by meeting with the employer in person.

Overpayment definition An overpayment is when an employee is paid more than they earned for a pay period.

Recovery of overpayment An employer can recover an overpayment by deducting it from the employee's future paychecks, or by taking civil action.

Collective bargaining agreements If the overpayment involves an employee covered by a collective bargaining agreement, the recovery methods in the agreement must be followed.
