A judgment lien is created after the entry of a judgment.
If you've been sued and lost the case by default (you didn't formally respond) or you lost on the merits, you are the judgment debtor. Your nonexempt property is subject to a lien.
A lien, generally, is defined as a legal right or interest that a creditor has in another's property, lasting usually until a debt or duty that it secures is satisfied.
A lien is imposed against a judgment debtor's nonexempt property. For a list of exempt personal property, see this

See here how a docketed judgment becomes a judgment lien against real property.
Other characteristics of a judgment lien:
- A judgment lien is a quick, simple and inexpensive enforcement procedure.
- Typically, the creditor does not take possession of the property on which the lien has been obtained.
- The creditor may simply sit back and wait to get paid when a debtor needs to sell or refinance the property.
- An improperly docketed and indexed judgment, including name misspelling, will invalidate the judgment (do a title search to verify proper recordation) and will protect a good-faith purchaser of the land subjected to the improperly indexed judgment.
- If you seek to enforce a judgment obtained in a different state, make sure your sister-state judgment is reduced to judgment and entered. Mere recordation of a sister-state judgment will not alone produce a lien against real property.
- A judgment lien on real property establishes priority over later claimants.
- A judgment lien attaches to practically all of the debtor's real property in the county where the judgment was entered.
- A judgment lien attaches to the debtor's after-acquired property provided the judgment is docketed in the same county as the real property.
- The judgment lien sticks to the property and assures priority to the judgment creditor as to after-acquired interests.
- A bankruptcy discharge may prevent the further reach a judgment lien. But a lien perfected more than 90 days prior to the filing of a bankruptcy petition will remain against the real property belonging to the debtor.
- A judgment lien is less disruptive to a debtor's business life since there is no immediate physical taking; therefore this lien is less likely to trigger a bankruptcy filing for relief.
- Filing of a notice of levy in the appropriate county clerk's office will prevent the owner of the property from disposing of that property without first discharging the lien.
- A judgment creditor can apply for an installment payment order to seize money you'll be receiving in the future, such as rental payments.
