How do you report a default judgment to the credit bureaus?

Judgments do not get "reported" to the credit reporting agencies. Independent contractors scan public records and then sell these documents to third party data furnishers. An example is Hogan/LexisNexis and Choicepoint. Records that pertain to credit, (judgments, tax liens, bankruptcy and foreclosure) are then re-sold to the CRA's. A consumer battling their own default judgment can have a disposition recorded at the same jurisdiction as the original legal item was filed. Plaintiffs can do the same with the original filing and trust the record will find its' way onto the defendant's credit report. Their is no other direct way for an individual or company to report a public record.
