If you’re co-parenting in Illinois and things are contentious, the record you keep today decides what you can prove later. The basics of good documentation are the same everywhere, but three things are specific to Illinois: its recording-consent rule, the words its courts use for custody, and where your case would actually be heard.
Recording conversations: Illinois’s consent rule
Illinois generally requires all parties' consent to record private conversations under its eavesdropping law. Do not record your co-parent without specific legal advice.
Whatever the recording rule, your own written documentation carries none of that legal risk: privately logging what you observe, with dates, facts, and photos of things you’re entitled to photograph, is lawful in every state. Our guide on admissibility covers how written records and messages are weighed.
What Illinois calls custody
Illinois uses the term allocation of parental responsibilities (decision-making) and parenting time rather than custody and visitation. Illinois retired the word custody in 2016: courts now allocate significant decision-making responsibilities in areas like education and health, and set a parenting-time schedule.
Where custody cases are heard
Custody matters in Illinois are handled by the Circuit Court. Illinois courts allocate parenting time and responsibilities in the child's best interests, considering each parent's participation in past caregiving, the child's adjustment, and each parent's willingness to place the child's needs first.
Why this matters for your documentation
In Illinois filings you won't fight over custody; you'll address decision-making areas one by one, which rewards records that are already categorized. A log that separates medical, education, exchange, and communication events by category mirrors how an Illinois court will actually carve up the decision-making allocation.
Keeping a record that holds up in Illinois
The discipline is the same in every state, and it’s covered step by step in our guides on documenting custody violations and keeping a custody journal: log events the day they happen, write facts rather than feelings, attach photos and screenshots to the entry they belong to, track shared expenses with receipts, and use a system whose edit history preserves originals so your record can prove it was never quietly rewritten.

Can I keep a custody journal in Illinois?
Yes. Keeping your own private, factual record of custody events is lawful everywhere in the U.S., including Illinois. Whether and how a journal is used in court depends on how it was kept: contemporaneous, factual, timestamped entries whose history can show they weren't rewritten carry the most weight. A Illinois family-law attorney can tell you how documentation is treated locally.
