The short answer
What Illinois families should know.
A spouse's phone or computer may contain relevant information, but marriage is not a reason to assume unrestricted access. Preserve material you lawfully possess and use counsel and the discovery process to obtain other evidence with appropriate limits.
Identify the evidence you actually need
Start with the disputed issue: a missing account, business income, parenting communication, or a particular transaction. Describe the relevant date range, application, and people involved. A request for every file on every device can expose unrelated private information and create unnecessary cost. A focused request is easier to evaluate for relevance, proportionality, and practical collection methods.
Preserve what you already have responsibly
Keep complete message threads, original files, and available dates rather than cropped screenshots alone. Record how the material came into your possession. Do not alter content, delete surrounding context, or forward a document in a way that loses useful information. If a shared device contains sensitive material, ask counsel how to preserve it without continuing an intrusive search.
Use formal requests and protective procedures
Illinois discovery rules address relevant documents and electronically stored information, subject to limits and protections. Depending on the issue, counsel may seek production from a party or a third party and address objections with the court. A forensic examination may require a defined scope, search terms, privilege review, and handling rules. Possessing the physical device does not answer every question about which information may be inspected.
Avoid creating a second dispute
Do not guess passwords, impersonate the spouse, install monitoring tools, or use someone else's credentials to reach private accounts. If you already accessed material and are unsure whether that was authorized, describe the facts candidly to counsel and stop further collection pending advice. Preserve relevant evidence rather than trying to erase the access history. The usefulness of digital information depends on reliable collection, context, and lawful presentation.
