Do I really need the original document, photo, or recording to prove what it says? Usually, yes - that is the basic idea behind the best evidence rule. When a party wants to prove the contents of a writing, recording, or photograph, the law generally requires the original item, or a legally acceptable duplicate, rather than someone's memory or a summary of it. The point is simple: if the exact contents matter, the court wants the most reliable version available.

In practice, this rule comes up when key facts are stored in paperwork, text messages, body-camera footage, repair invoices, medical records, or surveillance video. If a witness says, "I remember what the report said," that may not be enough if the wording itself matters. A copy is often allowed, but disputes can arise over whether it is complete, altered, or properly authenticated. That is where chain of custody and careful recordkeeping start to matter.

For an injury claim, the rule can affect whether a judge will consider a crash photo, estimate, recorded statement, or evacuation notice after an event like Red River flooding in Fargo. In North Dakota, this principle appears in North Dakota Rule of Evidence 1002, often called the "requirement of the original." If evidence has been lost or destroyed, related issues like spoliation can quickly become part of the fight.
