If a judgment goes against you, then you'll have to pay off the debts. You'll be provided a payment plan to help you repay the debt. However, if you are unable to make the debt payments, then your creditor may ask the court to garnish your wages or impose a judgment lien on your property. Once the judgment is paid, it will be reported on your credit report as "Paid Judgment".
A judgment has a negative impact on your credit score. Your credit score can go down by several points. Apart from that, a judgment gets reported on your credit report. A judgment remains on your credit report for 7 years or until it has been repaid whichever is shorter. Therefore, you should try your best to avoid getting a judgment against you.
