What to Do Before the Deadline Runs

  1. Pin down your accrual date — the day the clock started — and calendar the deadline conservatively.
  2. Preserve evidence now: photos, records, witness contacts, bills. Evidence decays faster than deadlines.
  3. Send preservation/notice letters where required (especially for Illinois government defendants).
  4. If the deadline is inside 6 months, treat it as urgent — filing suit is the only reliable way to stop the clock.

1 year for claims against local government entities under the Local Governmental and Governmental Employees Tort Immunity Act, 745 ILCS 10/8-101; shorter notice periods may apply
