Attorney Closing Requirements
Attorney-Closing State — An Attorney Is Required in Illinois
Illinois is an attorney-closing state. A licensed real estate attorney must be involved in the closing process. Even for FSBO commercial transactions, you will need to engage counsel to prepare or review the deed, handle fund disbursement, and ensure the transfer is properly recorded.
1031 Exchange in Illinois
Tax Deferral Strategy
Illinois conforms to federal 1031 rules. State imposes 4.95% flat income tax on capital gains; exchange provides meaningful state tax deferral.
Identification Window
45 days to identify replacement property after closing
Exchange Window
180 days to close on replacement property
Qualified Intermediary
A QI must hold proceeds — you cannot touch the funds
Commercial Disclosure Requirements
Illinois commercial disclosure rules are minimal; state residential disclosure act does not apply to most commercial transactions.
Even without mandatory disclosures, sellers should never misrepresent known material defects — doing so can create significant legal liability. A well-drafted purchase agreement with appropriate representations and warranties protects both parties.
