Like checking a driver's license before handing over the keys, authentication is the step where you prove a piece of evidence is what you say it is. In a legal or insurance claim, that means showing a photo, video, text message, repair bill, black-box download, or business record is real, unaltered, and tied to the right person, vehicle, or event. If you cannot clear that hurdle, the evidence can get ignored or thrown out no matter how convincing it looks.

This matters because cases are won and lost on records. A crash photo has to be shown as the actual scene. A truck log has to be tied to the actual driver and trip. A medical bill has to come from the actual provider. Under North Dakota Rule of Evidence 901, the party offering evidence has to produce enough proof to support a finding that the item is authentic. Rule 902 covers some self-authenticating records, which can come in without extra witness testimony if they meet the rule.

For an injury claim, weak authentication gives the other side an easy attack. They will say the video was edited, the text came from someone else, or the record belongs to a different crash. On western North Dakota roads, where heavy truck wrecks can involve dispatch records, GPS data, and fuel receipts, clean chain of custody and solid documentation can make the difference between a paid claim and a dead one.
