Illinois purchase and lease agreements
Name the document before deciding what it does. The purchase contract sets the buyer-seller deal. A lease sets the landlord-tenant bargain. The brokerage agreement records the consumer's relationship with the sponsoring broker. A signature on one does not automatically complete the others.

The short answer
A purchase contract sets terms for transferring an ownership interest; a lease sets terms for possession and use. Each is separate from the brokerage agreement. Illinois brokers may supply simple factual information in customary transaction forms within Quinlan's limited boundary. Rule 1450.775 separately controls intended blanks, signed changes, binding-form headings and true copies within 24 hours of each person's signing or initialing. Read the actual offer, conditions, notices and authority; a deposit alone does not establish a contract.
Reviewed October 25, 2026. Illinois II.M in the June 24, 2026 PSI broker outline covers purchase contracts, lease agreements and Chicago Bar Association v. Quinlan & Tyson. The whole Illinois License Act domain has 16 of 40 scored state questions; that is not a separate contract-topic quota. Current document rules and the July 13, 2026 brokerage-agreement rule are distinguished from the 1966 opinion. The page does not supply a transaction form, a universal review period or a complete local rental-law manual.
Read the document in six steps
- Identify the relationship and the interest. A buyer-seller contract, landlord-tenant lease and consumer-broker agreement govern different promises. Confirm the parties, property or premises, included interests and the authority of anyone signing for an owner, entity or trust.
- Track the proposal and acceptance. Identify the live offer, its expiration and required acceptance method. A materially changed price is a new proposal, not acceptance of the original price. A signature left on an earlier version does not by itself prove assent to the changed term. Read communication and delivery requirements.
- Separate consideration from the deposit. Bargained-for promises or performance can supply consideration. Earnest money is a deposit governed by the contract and escrow rules. A late deposit can still matter if the contract makes it a condition or an obligation; do not conclude that deposits are always essential or always irrelevant.
- Map the conditions and performance. Identify each financing, inspection, title, attorney-review or other condition, its deadline, required notice, cure or waiver process, and stated effect. For a lease, also identify commencement, expiration, rent, possession, deposit, use and assigned duties. Applicable law can limit a term; its presence on a form does not prove legality.
- Keep factual completion within the broker's role. Quinlan permits the limited insertion of simple factual data into the usual earnest-money or preliminary purchase-offer forms as an incident of brokerage. Choosing or drafting a custom legal remedy, giving a title or enforceability opinion, or preparing a deed or mortgage is not authorized merely by a broker license. A standard template does not turn legal judgment into clerical work.
- Protect every signed version. Do not plan to fill negotiated blanks after signing. For a later addition, deletion or alteration, obtain written consent or direction from all signatories and their signatures or initials on every change at the time made. Deliver the true original or corrected copy within 24 hours to the person signing or initialing. This applies before final mutual acceptance as well as after it.
| Issue | What controls | Practical distinction |
|---|---|---|
| Buyer-seller terms | Purchase contract and applicable law | Price, property, conditions, closing and remedies |
| Landlord-tenant terms | Lease and applicable law | Possession, rent, term and responsibilities |
| Consumer-broker relationship | Written brokerage agreement and agency law | Services, designated agents, compensation and duration |
| Factual form completion | Quinlan majority, limited incidental role | Straightforward negotiated facts, not custom legal advice |
| Intended later-filled blanks | 1450.775(a) | An unused inapplicable space differs from a deliberately unfinished term |
| Change to any signed document | 1450.775(b) | All-signatory written authority and authentication of every change |
| Copy to each signer or initialer | 1450.775(c) | Within 24 hours of that person's signing, not only after everyone signs |
| Binding-form heading | 1450.775(d) | Clearly state binding intent in large bold heading type |
| Electronic written agreement | 1450.775(e) and applicable electronic-transactions law | Same document-integrity rules; electronic form alone is not enough |
| Broker commission change | 1450.770(j)-(k) | Use proper signed brokerage amendment; no purchase-form workaround |
The distinctions that matter
| Distinction | How it works | What to notice |
|---|---|---|
| Earnest money vs. consideration | A deposit and the legal exchange supporting a bargain are different. Binding mutual promises can supply consideration, while a particular deposit obligation still has to be performed as agreed. | Read the deposit clause rather than choosing always required or never relevant. |
| Signature vs. final agreement | A signature is evidence to evaluate with the terms, authority, version and required acceptance or communication. An old signature does not automatically adopt a later price edit. | Identify exactly what each person accepted. |
| Counteroffer vs. amendment | A counteroffer proposes different terms before agreement. An amendment changes an existing agreement. A request or question is not automatically either. | First establish whether a contract already exists and what the communication says. |
| A signed document vs. a fully accepted contract | Rule 1450.775(b) protects any signed transaction document. Its restrictions are not postponed until both sides have accepted every term. | One signature is enough to make unauthorized editing a problem. |
| Brokerage timing vs. transaction signing | The seller agreement precedes marketing or listing. Ordinary buyer assistance uses 1450.770(h); seller-side work with an unrepresented buyer and dual agency have earlier specific requirements in(i). | A later purchase signature is not a substitute or an indefinite grace period. |
| A 1966 form-completion decision vs. current headings and services | Quinlan's discussion of preliminary offer forms does not waive 1450.775(d). Its historical brokerage discussion also does not erase current minimum-service duties. | Apply the case's legal-work boundary together with current law. |
Work through the facts
Fill facts or invent a remedy?
A customary form has blanks for the negotiated price and possession date. The buyer also asks the broker to invent a clause guaranteeing rescission and triple damages for a future boundary dispute.
- Simple negotiated facts fit the limited form-completion category.
- The custom remedy requires legal judgment about rights and enforceability.
Answer: Insert appropriate factual terms within the permitted role; refer the requested custom legal clause to counsel.
A changed price is not the original acceptance
The buyer signs an offer for $300,000. The seller changes it to $310,000. The broker treats the buyer's existing signature as agreement to the higher price.
- The original signature does not prove assent to the new price.
- Track the counterproposal's authority, authentication, delivery and acceptance. Rule 1450.775 also protects the already signed document.
Answer: No final higher-price agreement is established by the old signature alone.
The purchase contract does not do the buyer agreement's job
A broker has repeatedly advised a buyer, selected homes and negotiated an offer, but says the buyer-seller purchase contract automatically supplies the written brokerage agreement.
- The documents govern different relationships.
- Rule 1450.770(h) requires the buyer or tenant agreement before, or as soon as reasonably practical after, the described assistance. Other applicable rules may require it earlier.
Answer: Complete the proper brokerage agreement and applicable agency requirements; do not substitute the purchase contract.
The first signer gets a copy before final acceptance
A buyer signs Tuesday at 2 p.m. The seller will not consider the offer until Thursday.
- Rule 1450.775(c) ties delivery to the person's signing or initialing.
- The buyer's copy deadline is not postponed until the seller signs.
Answer: Deliver the true signed copy to the buyer within 24 hours, by Wednesday at 2 p.m. under these stated facts.
A phone-approved electronic edit
Landlord and tenant sign electronically. They later approve a new commencement date by phone. The manager edits the file and sends a screenshot of one paragraph.
- The rule applies to electronic writings.
- Phone approval alone is not all-signatory written consent or direction plus authentication of the actual change.
- A paragraph screenshot is not a true copy of the complete corrected lease.
Answer: Obtain the required written authority and signatures or initials, then deliver true corrected copies within the applicable 24 hours.
A signed blank left for tomorrow
A broker asks a buyer to sign while the financing deadline remains empty, intending to insert a date after speaking to the lender.
- That is a planned later-filled term, not an unused inapplicable field.
- Rule 1450.775(a) prohibits that intended post-signature completion.
Answer: Resolve and enter the term before signing; do not use the blank to avoid the signed-change requirements.
A binding form with a misleading heading
A form is intended to create a binding real estate contract but is designated only Offer to Purchase. The broker cites the terminology in Quinlan to justify it.
- Current 1450.775(d) requires the binding nature to be clearly stated in large bold heading type.
- It specifically bars that designation when the form is intended to be a binding real estate contract.
Answer: Follow the current heading rule. The older case's form terminology is not an exemption.
A financing condition is not the same as a preapproval
A hypothetical signed contract gives the buyer a right to terminate for denied financing only by a specified written notice received before its deadline. The buyer sends an earlier lender preapproval and assumes nothing else matters.
- Preapproval does not itself decide whether the contractual condition was fulfilled.
- Read the actual financing requirement, later decision and timely-notice process.
- Do not invent cancellation or deposit-forfeiture consequences from the word preapproval.
Answer: Apply the stated condition and notice terms; the preapproval alone does not resolve the contract's rights.
Mistakes to avoid
- A purchase contract automatically replaces the brokerage agreement They govern different promises and parties; current agency duties must also be considered.
- Every contract fails without an earnest-money check Consideration and a deposit are different; read the actual tender requirement.
- All signers have accepted every future edit Each changed signed term needs the required authority and authentication.
- Twenty-four hours starts only after the final seller signature The copy rule follows each person's signing or initialing.
- Any template may be filled in by a broker Quinlan preserves the legal-skill boundary, including deeds and mortgages.
- Electronic signing excuses document rules 1450.775 applies to physical and electronic written agreements.
- Every Illinois form comes with the same review period Read the applicable clause and law; do not invent a universal deadline.
- A seller's claim of default automatically releases earnest money Read the contract and escrow rule, including an actual known controversy.
- Historical language means broker services always stop at signing Current minimum services can continue through satisfaction or waiver of contingencies.
Check your understanding
These are original teaching questions, not recalled or predicted PSI questions. Answer first, then explain why the other choices fail.
1. Which document ordinarily records the buyer's services and compensation relationship with the sponsoring broker?
- The purchase contract automatically, without more
- The property tax bill
- The seller's deed
- The buyer brokerage agreement
Show answer and explanation
Answer: D. The buyer brokerage agreement
The brokerage agreement addresses the consumer-broker relationship. The purchase contract governs the buyer-seller deal; one does not automatically replace the other.
2. Which task most clearly fits Quinlan's limited form-completion permission?
- Draft a deed for the parties
- Design a new indemnity clause
- Give an opinion that a disputed cancellation is legally valid
- Insert the negotiated price and possession date in a customary preliminary form
Show answer and explanation
Answer: D. Insert the negotiated price and possession date in a customary preliminary form
The majority permits simple factual completion incident to brokerage. It does not authorize the other legal drafting or opinions merely because the person holds a broker license.
3. A buyer signs Tuesday at 2 p.m.; seller review occurs Thursday. When does 1450.775(c) require the buyer's true signed copy?
- At closing
- Within 24 hours of the buyer's signing
- Only after the seller signs
- Whenever the brokerage finishes the file
Show answer and explanation
Answer: B. Within 24 hours of the buyer's signing
Deliver to the person signing or initialing within 24 hours of that act. Waiting for the other side's signature is not the rule.
4. Only the buyer has signed. May the broker change a negotiated term before seller acceptance without the required authorization?
- No;1450.775(b) applies to the signed document
- Yes, if the broker believes the change is helpful
- Yes, if the old signature remains visible
- Yes, because no bilateral contract exists yet
Show answer and explanation
Answer: A. No;1450.775(b) applies to the signed document
The rule is not limited to fully accepted contracts. It requires written consent or direction from all signatories and authentication of every alteration when made.
5. Landlord and tenant want a signed lease term changed. Which process matches 1450.775(b)?
- A manager edits it after a phone call
- All signatories provide written authority and sign or initial each actual change
- The electronic platform may replace assent automatically
- Only the landlord initials it
Show answer and explanation
Answer: B. All signatories provide written authority and sign or initial each actual change
Written consent or direction and each signatory's authentication are required. Electronic format does not remove those requirements; corrected-copy delivery also applies.
6. A form is intended to be binding but is designated Offer to Purchase. Which rule applies?
- The title proves it cannot bind under any facts
- 1450.775(d) requires the binding nature in large bold heading type and bars that designation for the intended binding form
- No heading requirement exists
- Quinlan waives all modern heading rules
Show answer and explanation
Answer: B. 1450.775(d) requires the binding nature in large bold heading type and bars that designation for the intended binding form
Apply the current administrative rule. Historical use of preliminary-form terminology in Quinlan does not authorize an incompatible modern heading.
7. Which statement about earnest money is correct?
- It is essential to every possible contract
- It is a deposit governed by the contract and escrow rules; it is not always the required consideration
- It automatically belongs to the seller upon any cancellation
- It may be placed in the sponsored licensee's personal account
Show answer and explanation
Answer: B. It is a deposit governed by the contract and escrow rules; it is not always the required consideration
Mutual promises can supply consideration. A specific deposit obligation still matters, but the deposit is not an automatic formation requirement or forfeiture.
8. The buyer asks the broker to prepare a deed using an ordinary template. What follows from Quinlan?
- A template makes every legal instrument clerical
- A broker license alone does not authorize preparing the deed for the parties
- The parties' consent alone supplies a law license
- A broker may do it if no separate fee is charged
Show answer and explanation
Answer: B. A broker license alone does not authorize preparing the deed for the parties
The majority treats deeds, mortgages and later title instruments as legal work. Simplicity or a standard form does not supply the missing authority.
9. Can a purchase-contract form be used to change previously agreed brokerage commission-payment terms?
- Only an oral direction is needed
- Always, if the buyer signs
- No;1450.770(j)-(k) requires the proper written-and-signed brokerage change and bars the form workaround
- Only if the amount goes down
Show answer and explanation
Answer: C. No;1450.770(j)-(k) requires the proper written-and-signed brokerage change and bars the form workaround
A transaction amendment and a brokerage compensation amendment affect different promises. The purchase form is not the permitted shortcut for changing the existing commission terms.
10. Does Quinlan mean an exclusive broker's current minimum services always end when a purchase contract is signed?
- No; current 15-75 includes specified assistance through a signed agreement and satisfied or waived contingencies
- Yes, all duties end after acceptance
- No, but only because a universal attorney-review period always lasts thirty days
- Yes, the 1966 description overrides current statutes
Show answer and explanation
Answer: A. No; current 15-75 includes specified assistance through a signed agreement and satisfied or waived contingencies
Use the historical opinion for the practice-of-law boundary. Apply current 15-75 for its stated minimum services; do not substitute an old description of when brokerage work was performed.
Common questions
How are a purchase contract, lease and brokerage agreement different?
A purchase contract records the buyer-seller bargain for transfer of an ownership interest. A lease records the landlord-tenant bargain for possession and use. A brokerage agreement records the consumer-sponsoring-broker relationship, including services and compensation. Read each document's parties and purpose.
What makes an agreement a contract?
Identify offer, acceptance, consideration, competent parties, lawful purpose and sufficiently definite agreed terms, plus any applicable writing, signature or agreed formation requirements. The Illinois Courts contract materials explain these general concepts. A signature count or a deposit alone is not a complete formation analysis.
Is earnest money required for every Illinois purchase contract?
No universal rule makes a deposit the only possible consideration. Bargained-for mutual promises can support the contract. But the actual document may make tender a condition or impose a payment obligation. Read that term instead of treating a missed deposit as either automatic invalidity or something that never matters.
Does changing the price accept the original offer?
A materially changed price proposes different terms. Establish the new proposal, required authority, communication and acceptance rather than relying on an old signature. A mere inquiry or request for information is not automatically a counteroffer; read the objective words and context.
Must every purchase contract and lease be written?
Illinois land-sale enforcement generally requires the signed writing described in the Frauds Act. Lease terms and the separate one-year-from-making rule need their own analysis; do not treat a planned quick land closing as an exemption or declare every oral short lease automatically void. Other statutes, local duties and the parties' own terms can matter. The linked statute-of-frauds guide addresses the distinctions and exceptions.
Can electronic signatures satisfy a writing requirement?
Applicable Illinois electronic-transactions law recognizes electronic records and signatures rather than denying effect solely because of their format. Agreement to transact electronically, attribution, authority, retained records and other substantive requirements still matter. An email or platform mark is not automatically everyone's assent to every version. Rule 1450.775 applies to electronic written agreements too. A platform timestamp does not cure an unauthorized post-signature edit.
What may a broker do under Quinlan?
Within the opinion's limited incidental role, a broker may supply simple factual data in customary preliminary transaction forms. Examples include negotiated price, names and possession date. The majority draws a different line for deeds, mortgages, title instruments and legal judgment. This is permission for a limited task, not general authority to practice law. Its discussion of preliminary sale forms is not blanket permission to draft any lease or create custom legal clauses.
Does a standard template make legal drafting permissible?
No. The nature and context of the work control. Creating a custom remedy, selecting legal language to produce a particular consequence or giving a title or enforceability opinion can require legal skill even if a form library is available. A broker license alone does not supply that authority.
How can Quinlan mention offer forms when today's heading rule is stricter?
The 1966 opinion addresses the limited factual-completion boundary. Current 1450.775(d) separately requires forms intended to become binding real estate contracts to state that fact in large bold heading type and prohibits using a form designated Offer to Purchase for that binding purpose. Apply both; do not treat historical terminology as a current form approval.
Are all blank spaces prohibited?
No. Rule 1450.775(a) targets blanks the licensee intends to fill after the parties sign or initial. An unused inapplicable space is different from a financing deadline deliberately left unfinished for later unilateral entry. Resolve the negotiated term and use the proper signing process.
Does the signed-change rule wait until everyone accepts?
No. Rule 1450.775(b) applies to any signed transaction contract or document. It requires all-signatory written consent or direction and every addition, deletion or alteration to be signed or initialed by all signatories when made. A partly signed proposal is not open to unrestricted editing.
When must the signer get a copy?
Deliver a true copy of the original or corrected document within 24 hours after that person signs or initials. Do not start the buyer's clock only when the seller later accepts. A complete matching copy is different from a screenshot of one changed paragraph or an internal file note.
When is the brokerage agreement required?
Under 1450.770(g), the seller or owner agreement precedes marketing or listing. Subsection(h) addresses ordinary buyer or tenant assistance before or as soon as reasonably practical after the described licensed work. Subsection(i) adds earlier conditions for seller-side assistance to unrepresented consumers and dual-agency services. A missing writing does not automatically establish that no agency duties exist.
May the transaction contract change the broker's commission?
Rule 1450.770(j) requires the stated brokerage compensation amendments to be written and signed. Subsection(k) prohibits using real estate contract forms to change previously agreed commission-payment terms. Read any transaction concession separately; it is not a universal substitute for the proper brokerage amendment.
Does every contract include attorney review or an inspection escape?
Do not invent one from the word Illinois. Read the actual clause, applicable law, deadlines and notice method. A financing denial, inspection finding or repair request can have different effects under different wording. This page does not supply a universal approval period or an automatic right to cancel.
Does a seller's default claim automatically release earnest money?
No. Follow the contract and escrow authority. Rule 1450.750(h) also addresses an actual known controversy over entitlement, not merely a formal written objection. Do not treat every dispute as automatic seller forfeiture or claim that every lawful release uses the same paperwork.
Do minimum brokerage services stop at contract signing?
Current 15-75 requires the specified exclusive-brokerage services, including assistance with offers, counters and related notices through a signed agreement and satisfaction or waiver of contingencies, plus related answers. Quinlan's historical practice-boundary discussion does not override those current obligations.
Do these examples validate an actual lease or predict a passing score?
No. Applicable residential, commercial, fair-housing, deposit, disclosure and local laws can affect particular terms. These are original educational questions, not PSI questions, an approved form or a validated passing prediction. Use practice mistakes to identify which document or rule you need to reread.
