What the landlord had to send
If the landlord keeps part of the deposit, check the itemization and its cost support. 765 ILCS 710/1(a)-(b) - Property-damage deductions generally require paid receipts or permitted estimates and follow-up receipts; subsection (b) provides an alternative when receipts cannot be produced through no fault of the lessor
What proof matters most
Photos, move-out condition notes, receipts, and written communications are the core proof if this dispute escalates.
