I do not work for a law office and would like to issue a motion for discovery to access a police report in essex county. Can I do this on my own and where do I find a legit example to create one from?

"Discovery" usually refers to the investigation process during a lawsuit. Is there a lawsuit ongoing in your situation? Or, are you referring to an individual's request for copies of a police report? Not all documents are considered "public record." You can contact the police department for more information. Any additional information you can provide may help you get better responses.
