The short answer
What Illinois families should know.
A photo or video can help a judge understand an event, but it is not automatically self-explanatory evidence. Illinois Rule of Evidence 901 requires a sufficient basis to find that an item is what its proponent claims. Relevance, completeness, and other objections may still need to be addressed.
Preserve the original and its context
Keep the original file when available, along with the source, date, device, and surrounding sequence. An isolated screenshot may omit what happened immediately before or after. Do not crop, enhance, annotate, or overwrite the only copy. If an enlarged or labeled version will help the court, retain the unchanged original so the presentation can be compared with the source.
Identify who can establish authenticity
Rule 901 offers several possible methods, including testimony from a knowledgeable witness and evidence about a reliable process or system. The correct foundation depends on the item. Someone who observed the scene may explain what a photograph depicts; an automated recording may require a different foundation. The person offering the evidence should not assume that recognizing a familiar face answers every question about the file’s origin or accuracy.
Separate what the image shows from what it suggests
A photograph may show a condition without proving when it arose or who caused it. A short clip may show words or conduct while omitting important context. Describe the limited proposition the item supports and identify other evidence needed for the rest. This is especially important where a dramatic image could distract from the precise issue the court is deciding.
Plan disclosure and courtroom playback
Counsel should address required exchange, exhibit labeling, file format, audio quality, and the court’s presentation procedure before the hearing. Test playback without changing the source. If statements in a recording are offered for their truth, hearsay questions may arise independently of authenticity. Lawful acquisition is also a separate issue; evidentiary usefulness does not itself authorize making or obtaining a recording.
