A personal injury demand letter is the starting point for settlement negotiations in a personal injury claim. It essentially lets the other party know that you are seeking damages for the injury or injuries that resulted from their negligent actions. As this letter begins the settlement negotiation process for personal injury claims, it is important that your demand letter is well constructed and that you present your damages in a professional, straightforward manner. While a poorly written letter can gravely hurt your case, a well-written demand letter can set the stage for a quick and equitable settlement process.
