A demand letter is a formal document your Houston attorney sends to the at-fault party's insurance company to start settlement negotiations. It lays out the facts of the accident, describes your injuries and the medical treatment you received at facilities like Memorial Hermann, Methodist, or Ben Taub, documents your financial losses including medical bills and lost wages, and states a specific dollar amount you are demanding as compensation. The letter explains the legal basis for holding the other party responsible and how their negligence caused your injuries. While Texas law does not require a demand letter before filing in Harris County District Court, sending one is standard practice because it gives the insurer a clear picture of your claim and a chance to settle without litigation. A strong demand letter signals you are prepared to go to trial if necessary and creates a paper trail that can benefit your case later. Your attorney typically sends the demand letter after you reach maximum medical improvement so the full scope of your damages is documented.
