What to do if your Illinois landlord won't return your deposit

  • Confirm the 45-day window has passed since you provided a forwarding address.
  • Document the unit's move-out condition with photos and any walk-through notes.
  • Send a formal demand letter citing Illinois's deposit return deadline and statutory damages.
  • If the landlord ignores your demand, file in small claims court — Illinois allows up to 2x damages for wrongful withholding.
