The short answer
What Illinois families should know.
The original-document rule concerns proving the contents of a writing, recording, or photograph. It does not mean a divorce case requires the best imaginable proof of every fact. Illinois also permits many duplicates and recognizes circumstances in which other evidence of the contents may be used. Authenticity and fairness still matter.
Identify what the document is being used to prove
If the dispute concerns the terms of an agreement or the exact words of a message, the contents are central. A witness who personally observed a separate event may have evidence of that event independent of a later document. Counsel should identify the purpose of the proposed evidence before deciding whether Rule 1002's original requirement applies.
A reliable copy may be sufficient
Rule 1003 generally permits a duplicate unless there is a genuine authenticity question or using the duplicate would be unfair in the circumstances. A complete, legible copy is therefore different from a cropped image whose missing portions matter. Electronic material also requires attention to the applicable definitions and authentication. Preserve the native file or account export when available instead of repeatedly saving edited screenshots.
A missing original requires an explanation
Rule 1004 addresses situations such as loss or destruction without bad faith, inability to obtain an original through available judicial procedures, and certain originals controlled by an opponent. The exception is not permission to discard documents. The party offering substitute proof should be ready to explain what existed, what happened to it, what efforts were made to obtain it, and why the substitute accurately reflects its contents.
Plan for the actual disputed issue
For a bank transaction, obtain complete statements and associated records rather than relying on a handwritten total. For a text exchange, preserve participants, dates, and surrounding messages. For a signed agreement, locate all pages and amendments. Resolving these problems before the hearing gives counsel time to request records, arrange foundation testimony, and address an authenticity dispute without interrupting the presentation of the case.
