Attorney Review Period Illinois: How It Works and What Can Go Wrong

In most states, once you sign a purchase contract, you're in it. Illinois is different: there's a built-in five-business-day window after contract execution where attorneys on both sides can review, modify, or outright kill the deal — and the buyer gets their earnest money back if they walk.

But this window only protects you if you understand how it works. Get it wrong, and you can inadvertently waive your rights, lose your earnest money, or void a deal you actually wanted to close.

What the Attorney Review Period Is

The Illinois Multi-Board Residential Real Estate Contract (Version 7.0) — the standard purchase contract used in Cook County and the collar counties — contains an attorney review and inspection contingency period under Paragraph 10.

Both parties have five business days from the date of acceptance (the date both buyer and seller have signed the contract) to have their attorneys review the agreement. During this window, attorneys can:

  • Approve the contract as written
  • Propose legal modifications
  • Disapprove and terminate the contract

If five business days pass with no attorney action, the contract becomes fully binding exactly as written.

This period is not an Illinois statutory requirement — it's a standard contract provision. The Chicago Association of Realtors (CAR) contract also includes attorney review, using similar mechanics.

How the Five-Day Clock Runs

The five days are business days only. Saturdays, Sundays, and federal holidays do not count.

The clock starts on the first business day after the date of acceptance — not on the day of acceptance itself. Day one is the first full business day following the day both parties signed.

Example: If you and the seller both sign on Friday, Day 1 is the following Monday. Day 5 is the following Friday. If you need an attorney to act, they must do so by close of business on that Friday.

This means a Friday acceptance gives you the full following week. A Monday acceptance gives you through the following Monday. In a competitive market where you're under pressure to get an attorney retained immediately, the timing matters.

Modifications vs. Suggested Changes: A Critical Legal Distinction

Under the Multi-Board 7.0 contract, there are two different types of attorney communications — and they have radically different legal consequences.

Paragraph 10(c): Modifications

If an attorney proposes a modification to the core terms of the contract, this functions legally as a counter-offer. Under Illinois common law, a counter-offer rejects the original contract and opens the entire agreement back up for negotiation.

If the parties cannot reach written agreement on the proposed modifications within ten business days of acceptance, either party may terminate — and the earnest money returns to the buyer.

The legal hazard: a modification counter-offer restores the other party's freedom to accept a backup offer instead of responding to yours.

Paragraph 10(d): Suggested Changes

If an attorney labels their communication as a "suggestion" or "recommended change" (rather than a modification), it is not a counter-offer. The original contract remains binding whether or not the other party agrees to the suggestion.

In practice, experienced Illinois real estate attorneys are precise about which mechanism they use. A buyer's attorney proposing major changes to financing contingencies or inspection terms should be using modifications, not suggestions. A buyer's attorney requesting minor clarifications on personal property can often use suggestions without opening up the whole deal.

What Attorneys Typically Do During Review

For the buyer's attorney, the five-day window is used to:

  • Review the contract terms for unfavorable provisions or missing contingencies
  • Confirm the financing and inspection contingency language protects the client
  • Clarify what personal property (appliances, fixtures, window treatments) conveys with the home
  • For condominiums: review HOA financial documents, reserve funds, meeting minutes, pending special assessments, and rental cap provisions
  • Identify any provisions that need modification before the contract becomes binding

The home inspection typically happens concurrently with attorney review. If the inspection reveals problems — a failed furnace, evidence of basement flooding, knob-and-tube wiring — the buyer's attorney formalizes the repair request or credit demand during this window.

Common Buyer Mistakes

Delaying Attorney Engagement

The most common mistake is waiting until after you accept an offer to find a real estate attorney. By the time you locate someone, confirm availability, and they receive the contract documents, you may have lost two or three days of the five-day window. Get your attorney identified before you start making offers.

Using Attorney Review to Renegotiate Price

The attorney review period is for legal review — it is not a mechanism to get a better price because you changed your mind. Attempting to use modification threats as leverage to extract a price reduction is considered bad faith negotiation in Illinois. Sellers who receive this approach can reject the modification, stand on the original contract, and pursue a backup offer.

Attorneys are permitted to raise issues related to legal provisions, contract contingencies, zoning requirements, or newly discovered property conditions — not to relitigate a price both parties already agreed to.

Missing the Window on Condo Due Diligence

For condominium purchases, the attorney review period is the only time you can audit the HOA. After the window closes, you've accepted the condo association's financial condition as-is. Your attorney should obtain and review:

  • Current reserve fund balance
  • Reserve study projections (are they adequately funded?)
  • Meeting minutes for the past two to three years (any deferred repairs, pending litigation, owner complaints?)
  • Pending or recently approved special assessments
  • Rental cap provisions (can you rent the unit if your life circumstances change?)
  • Percentage of units currently owner-occupied vs. rented

A condo with depleted reserves and deferred roof replacement is a future special assessment waiting to happen. You need this information before the five-day window closes.

How This Differs From Downstate Illinois

Cook County and the collar counties (DuPage, Lake, Will, Kane, McHenry) use attorney-driven closings where legal representation at closing is standard practice. The five-day attorney review is a core feature of every transaction.

Downstate Illinois — Springfield, Champaign, Peoria, Rockford — relies primarily on title companies to handle closings. Attorneys are less commonly retained, and their role in the closing process is more advisory when they are involved. The five-day attorney review provision may still exist in the contract language, but it receives less emphasis because the closing infrastructure is different.

If you're buying in Cook County for the first time after experience in a title-company state, the attorney involvement here is not optional overhead — it's the system. Budget $500–$1,500 for a flat-fee real estate attorney and retain them before your first offer.


The attorney review period is Illinois's strongest built-in buyer protection. Using it correctly starts with getting the right legal representation engaged before your offer is accepted.
