In Oregon, a creditor can get a judgment to garnish 25% of the debtor's disposable earning, that is, wages left after your employer has made the necessary deductions as per law. The debtor usually learns about the garnishment from the employer or from the bank. The debtor is supplied a form indicating the name and address of the creditor along with a calculation of the amount owed to the creditor.

Tell me one thing. Are you being sued or have creditors threatened to sue you? If a lawsuit has been filed, have you lost the case?
Your wage can't be garnished until you have lost the case.
