Not a lawsuit, a court filing, or a guarantee that an insurer will suddenly play fair. A demand letter is a written notice sent before or during settlement talks that explains what happened, why another person or business is legally responsible, what losses resulted, and how much money is being requested to resolve the claim.

Used well, it puts facts, injuries, medical records, lost wages, and a settlement number in one place. Used badly, it can box an injured person into a weak position. If the letter understates future treatment, overlooks pain and limitations, or asks for too little too soon, the insurance company may treat that number like an anchor and build the rest of the negotiation around it. After a crash on black ice or a commute-related collision near Minneapolis, that can matter a lot if care later expands at a hospital such as Hennepin Healthcare.

For an injury claim, a demand letter often opens settlement negotiations and can show the other side that the case is organized and documented. But it does not replace filing a lawsuit, and it usually does not stop the statute of limitations from running. In Minnesota, many negligence claims are governed by Minn. Stat. § 541.05 (2024). Miss that deadline while waiting on a response, and a strong claim can be lost.
