The Illinois attorney review period is a contract provision, not a statute. Under Paragraph 13 of the Multi-Board Residential Real Estate Contract 8.0, the current standard form, each party's attorney has five business days from acceptance to approve, disapprove or propose modifications other than the purchase price, and either party may terminate if no agreement is reached within ten business days.

People describe attorney review as though Illinois law grants it. It does not.
There is no Illinois statute creating an attorney review right. It exists because the standard contract forms used here contain the provision, and because practice in this market is that both parties are represented.
The Illinois State Bar Association's consumer guide puts the responsibility on the buyer to make sure it is there: be sure the offer provides an attorney approval and modification contingency giving your attorney a reasonable period to review and revise the terms.
That distinction has a practical consequence. The length and scope of the period are whatever your contract says. Read the clause in the document you are actually signing rather than relying on the customary five days.
The operative form in this market is the Multi-Board Residential Real Estate Contract 8.0, effective February 1, 2025 and still current. It is produced by the Multi-Board Joint Venture, a group of REALTOR® associations and bar associations that includes the North Shore-Barrington Association of REALTORS®, which is the board covering this market, alongside the Chicago Association of REALTORS® and the Illinois Real Estate Lawyers Association, which publishes the official version. If your contract says 7.0, you are on a superseded form.
In 8.0 the provision is Paragraph 13. The mechanics:
Within five business days after the Date of Acceptance, the parties' attorneys may approve the contract, disapprove it, or propose modifications.
Modifications may be proposed except for the purchase price, and a disapproval may not be based solely on the purchase price.
If written agreement has not been reached within ten business days after the Date of Acceptance, either party may terminate on notice.
That ten day clock is worth getting right. It runs from the Date of Acceptance, not from the end of the five day review window. Secondary write-ups get this wrong regularly, and the difference is a week.
Inspection outcomes, closing date, possession, personal property, contingency deadlines, allocation of costs, survey requirements, and the handling of any municipal point-of-sale requirement are all commonly adjusted here.
Price is carved out of the modification right. In practice a credit negotiated in response to inspection findings reaches a similar economic result by a different route, which is why attorney review and the inspection contingency are worked together rather than sequentially.
Attorney review and the inspection contingency normally run in the same window. That compression is deliberate and it is demanding.
An inspection scheduled on day three leaves no time to get the report, digest it, price the issues and negotiate a response before the review period closes. An inspection scheduled on day one leaves room.
So: book the inspection immediately on acceptance. Not after a couple of days of being pleased with yourself. Immediately.
Extensions are possible by written agreement, but they require the other side to agree, and in a competitive situation with a backup offer waiting, they may not.
Three ways.
The attorneys agree modifications and the contract proceeds as amended. This is the ordinary outcome.
The period expires without disapproval and the contract stands as written.
An attorney disapproves within the period, agreement is not reached, and the contract terminates with earnest money handled per its terms.
The third outcome is real and it happens. It is also the point at which most Illinois contract disputes get resolved on paper rather than later.
More than review the contract, which is the part people picture.
They read the contract against what you actually agreed and what you actually want, and propose modifications where the two diverge.
They read the seller's disclosures, including the Residential Real Property Disclosure Report and the lead paint disclosure where the property predates 1978, and tell you what the answers imply and what they conspicuously do not say.
They order and review the title commitment, which shows liens, easements, restrictions and anything else attached to the parcel. Easements in particular surprise buyers, because they are invisible on a viewing and permanent in effect.
They review the survey, where one is provided, for encroachments and boundary problems.
They coordinate with the lender on timing so the contingency dates and the closing date are actually achievable.
And they negotiate the inspection response, which in most transactions is where the real money moves.
That is a lot of work for a five day window, which is the argument for engaging them before you write the offer rather than after it is accepted.
Having seen a number of these, the same items recur.
Closing and possession dates, particularly where a party is buying and selling on the same day, which is common and fragile.
Post-closing possession, meaning the seller staying in the property for a period after closing, with the rent, the deposit and the condition at handover all needing to be specified.
Personal property, which sounds trivial until the appliances, the window treatments, the playset or the wine fridge turn out to be disputed at the walk-through.
Inspection response deadlines, extended where a specialist inspection is needed, for example on a septic system, a well, a pool or a foundation concern.
Municipal requirements, including point of sale inspections and transfer stamp conditions, allocated between the parties and built into the timeline.
Survey, who provides it and to what standard.
Well and septic testing where applicable, which in parts of Lake County it is.
None of these are price. All of them are money.
The five day provision comes from the standard residential contract. Two common situations do not use that contract.
New construction. Builders use their own contract, and it will not contain the Multi-Board attorney review provision. Some builder contracts allow a short review window, some allow none, and some are presented as non-negotiable. Your attorney can still review it, but the leverage and the timeline are different, and you should know that before you sign rather than after.
For sale by owner. Whatever contract the parties use is what governs. If a FSBO seller presents a contract with no attorney review provision, you are not protected by custom. Ask for the provision to be added, and be prepared for the seller not to understand why.
In both cases the protection you are relying on comes from the document, not from being in Illinois. Read the document.
Illinois residential real estate attorneys generally work on a flat fee for a standard purchase or sale, quoted in advance, rather than hourly. That is the market norm and you should expect a number before you engage.
The fee typically covers the contract review and modification, the title commitment review, coordination with the lender and the title company, the negotiation of the inspection response, preparation or review of closing documents, and attendance at closing.
What is usually extra: unusual title problems, a short sale, an estate or trust transaction, litigation, or a transaction that falls through and restarts.
Ask what is included, what is not, and what happens to the fee if the deal dies during attorney review. Ask whether they will attend closing in person or remotely. And ask how quickly they respond, because in a five business day window a slow attorney is an expensive one regardless of the fee.
Engage your attorney before you write or accept an offer. The window runs from acceptance. An attorney coming to the file cold on day two is working with three days to review, advise and negotiate. Attorneys who have already seen the disclosures and the survey work faster and better.
Respond promptly to proposed modifications. Silence runs the clock and preserves nothing.
Do not treat it as a free look. Using attorney review to renegotiate a deal you simply regret damages your credibility with the other side, and where a backup offer exists it can cost you the property outright. The provision exists to fix genuine problems found in diligence, and the other side's attorney can tell the difference.
Nothing here is legal advice. Your attorney advises on your contract.
What you pay at the end of the process is broken down in closing costs in Illinois, and the rest of the purchase is in my notes on buying in this market.
Five business days from the Date of Acceptance under Paragraph 13 of the Multi-Board Residential Real Estate Contract 8.0. This is set by the contract rather than by statute, so read the provision in the document you are signing, since the window and its scope are whatever that form specifies.
No. There is no Illinois statute creating the right. It exists because the standard contract forms contain the provision and because practice here is that both parties are represented. The Illinois State Bar Association advises buyers to make sure their offer actually includes the contingency.
Not directly. Paragraph 13 excludes the purchase price from the modification right and prohibits a disapproval based solely on price. In practice a credit negotiated in response to inspection findings achieves a similar economic outcome, which is why the two processes are worked together.
If written agreement on proposed modifications has not been reached within ten business days after the Date of Acceptance, either party may terminate on notice. Note that the ten days runs from acceptance, not from the close of the five day review window, which secondary sources frequently get wrong.
Before you write or accept an offer rather than on the day of acceptance. The review window runs from acceptance, so an attorney coming to the file cold on day two is effectively working with three days to review disclosures, advise you and negotiate modifications on your behalf.
