Evidence and discovery

Police Reports and Proof in an Illinois Divorce Hearing

A police report can identify witnesses and preserve leads, but its contents are not automatically admissible. Current evidence rules require a closer analysis.

The short answer

What Illinois families should know.

A police report may be important to understanding an incident, but handing it to the judge does not automatically prove every statement in it. Authentication, hearsay, personal knowledge, and the current public-records rule must be considered. The report often helps identify the evidence that should be obtained next.

Separate the report’s different components

A report may combine an officer’s observations, statements from several people, photographs, conclusions, and administrative information. Those components can raise different evidentiary questions. A person’s allegation recorded by an officer remains that person’s statement; writing it in a government document does not necessarily establish that the allegation is true. Identify who can testify about each significant event.

Use the current public-records rule

The current text of Illinois Rule 803(8) contains specific limitations involving police accident reports and matters observed by law-enforcement personnel. The rule also addresses qualifying factual findings from legally authorized investigations. Do not rely on a broad summary that all government reports are admissible. Counsel should analyze the actual document and current rule, including whether another proper basis for particular evidence exists.

Preserve underlying evidence promptly

Body-camera footage, dispatch information, photographs, recordings, and the testimony of people present may provide different or more complete evidence than the narrative report. Availability and retention can vary. Give counsel the incident number, agency, date, and names promptly so appropriate preservation and records procedures can be considered. Do not edit recordings or circulate sensitive material publicly.

An investigation is not the family court’s entire decision

The existence or absence of a charge does not tell the family court everything about the disputed family-law issue. The court needs admissible evidence tied to the relief requested. Focus on specific conduct, dates, and effects rather than assuming the police response automatically resolves the parenting or safety question. A complete, carefully supported account is more useful than overstating the report’s legal significance.

Prepare

Useful next steps

  • Keep the incident number and complete report with all available attachments.
  • Identify witnesses who personally observed the events.

  • Assuming a report proves each allegation merely because an officer recorded it.
