Offers, Binders, Options, Installment Sales and the Attorney Boundary

The salesperson's safest rule is equally important: communicate authorized business terms and use brokerage-approved forms within the narrow limits New York recognizes, but do not draft legal protections or tell a party what a disputed document legally means. The New York Department of State treats the boundary seriously.

The four documents at a glance

Official source map

The New York Department of State 77-hour salesperson curriculum includes offers, binders, options, installment purchase contracts, contract preparation and unauthorized practice of law within the contracts subject.

The core authorities are:

• General Obligations Law section 5-703: a contract to sell real property generally must be in a sufficient writing subscribed by the party to be charged.
• General Obligations Law section 5-1109: a signed written offer stating that it is irrevocable for a stated period is not invalid merely because no consideration was given for that promise.
• 929 Flushing LLC v 33 Development Inc.: a binder can bind when it identifies the parties and property, states essential terms, is properly signed and shows a meeting of the minds, but the binder in that case failed those requirements.
• Urban Archaeology Ltd. v Dencorp Investments, Inc.: an option generally must be exercised strictly according to its terms.
• Broadwall America, Inc. v Bram Will-El LLC: an option is an irrevocable offer during its bargained-for period and becomes a bilateral contract when properly exercised.
• Cloke v Findlan and Lambert v Schiller: an installment land contract and part payment can give the purchaser equitable title and an equitable lien.
• Department of State Legal Memorandum LI04: the official guide to the limited form assistance a broker or salesperson may provide without practicing law.
• Moran v Erk: a bilateral attorney-approval condition protects attorney judgment and helps keep broker-prepared forms within the lawful boundary.

Part 1: the offer

An offer is a proposal that gives another person the power to accept and form a contract. It must be definite enough that acceptance identifies the promised transaction rather than opening a new negotiation.

For a real estate purchase, the offer commonly addresses:

• buyer and seller
• property
• purchase price
• proposed deposit
• financing
• inspection or due-diligence terms
• included and excluded items
• anticipated closing
• occupancy
• expiration
• attorney review or preparation of a formal contract

An offer sheet can collect these terms without becoming the final contract. Its legal effect depends on the words, signatures, completeness, circumstances and objective intent.

Offer, invitation and negotiation

A listing advertisement usually invites offers. It is not ordinarily a promise to sell to anyone who states the asking price.

A buyer's message saying “Would seller consider $600,000?” is usually an inquiry. A signed writing stating definite purchase terms and inviting seller's acceptance is more likely an offer.

What can happen to an offer?

An offer can end through:

• rejection
• counteroffer
• valid revocation before acceptance
• expiration
• death or incapacity in circumstances where contract law ends the power of acceptance
• failure of a stated condition
• acceptance, which transforms the offer into a contract if the other requirements are met

A counteroffer generally rejects the original terms and proposes new ones. “I accept if seller includes the dining table” is not an unconditional acceptance if the table was excluded.

Offer expiration

If an offer says it expires at 5:00 p.m. Friday, a later attempted acceptance does not ordinarily revive it. The original offeror can choose to renew the proposal, but the offeree cannot do so alone.

Keep time zones, delivery method and actual receipt requirements clear. A signature completed before the deadline but never delivered as required may not be effective acceptance.

Revocation and ordinary offers

An ordinary offer can generally be revoked before effective acceptance. The offeror should communicate revocation clearly and through the required channels.

An option is different because it can make the underlying offer irrevocable for the option period.

Accepted offer does not always mean signed sales contract

In many New York residential transactions, agents negotiate an accepted offer and then send a deal sheet to attorneys, who prepare and negotiate the formal contract. That common workflow does not create one rule for every document.

Ask:

1. Did the parties sign a writing?
2. Does it contain the essential sale terms?
3. Does it state that no party is bound until a later contract is signed?
4. Is it subject to attorney approval?
5. Does it reserve material points for later negotiation?
6. Does the language show present intent to be bound?

“Accepted offer” can describe a business milestone without answering the legal formation question.

Scenario: deal sheet only

Buyer and seller agree through agents on price and anticipated closing. The deal sheet states that it is nonbinding and subject to negotiation and execution of a contract by the parties' attorneys.

Best analysis: The business terms are accepted, but the writing expressly postpones legal commitment. Do not call it a completed sale contract.

Scenario: complete signed writing

A writing identifies both parties and property, states price and payment terms, contains the material conditions, is signed by the party to be charged and says the parties intend to be bound now despite later preparation of a longer document.

Best analysis: A later formal document does not automatically make the existing agreement nonbinding. Content and intent control.

Deposits delivered with an offer

Money accompanying an offer is often called an earnest-money or binder deposit. Its name does not decide who owns it or when it may be released.

The writing and escrow terms should address:

• who receives the money
• whether it will be deposited before contract formation
• when it becomes part of the contract deposit
• what happens if seller rejects the offer
• what happens if attorneys do not approve
• how a dispute is handled

A deposit does not make an otherwise incomplete document enforceable by itself. It is evidence and consideration in the broader transaction, not a substitute for essential terms, subscription and intent.

A salesperson should provide a receipt and follow supervising-broker procedures. The salesperson should not promise automatic refund or forfeiture when the parties dispute entitlement.

Part 2: the binder

A binder is usually a short writing recording proposed or agreed transaction terms before a longer contract. New York law does not give every binder the same effect.

When a binder may be enforceable

929 Flushing explains that a real estate binder can be enforced when it:

• identifies the parties
• describes the property
• states the essential terms
• is signed by the party to be charged
• reflects a meeting of the minds and present intent to be bound

The contemplated preparation of a more formal contract does not, by itself, destroy an already complete agreement.

When a binder may be only preliminary

A binder can fail when it:

• omits or misidentifies a party
• leaves price or payment structure unsettled
• fails to identify the property adequately
• reserves material points for future agreement
• is expressly subject to execution of a mutually acceptable contract
• shows that the parties did not intend present legal commitment

In 929 Flushing, the binder did not correctly identify the parties and left significant subjects unresolved. The court treated it as an unenforceable agreement to agree.

The word “binder” proves little

Calling a document “binder,” “memorandum,” “offer,” “letter of intent” or “deal sheet” is not decisive. Courts examine its substance.

Exam rule: Identify essential terms, signatures and intent. Never select an answer solely because of the document title.

Part 3: the option to purchase

An option gives the optionee the right, but not the obligation, to purchase on stated terms within a stated period. The optionor promises to keep the offer available according to the option agreement.

Before exercise:

• optionor is bound to keep the offer open as agreed
• optionee may choose whether to exercise
• the sale itself has not yet been completed

On timely and proper exercise, the option ripens into an enforceable bilateral purchase contract.

Consideration and signed irrevocability

Options commonly use consideration to support the promise to hold the offer open. New York General Obligations Law section 5-1109 also says that a signed written offer stating it is irrevocable for a specified period is not invalid merely because no consideration was given for the assurance of irrevocability.

That statute does not fix missing property terms, defective authority or noncompliance with the Statute of Frauds.

Options concerning real property require a sufficient writing

An option to buy an interest in real property is within the Statute of Frauds. The writing must identify the option and essential sale terms and be subscribed as required.

Exercise must follow the option

New York courts generally require strict compliance with an option's exercise terms. Check:

• exercise deadline
• required notice form
• required recipient and address
• delivery method
• payment accompanying exercise
• whether notice must be received or merely sent
• identity of the exercising party

Broadwall emphasizes that time is of the essence in an option to purchase real property. Waiting for a convenient closing custom does not extend an option deadline.

Worked option example

Owner gives tenant a written option to buy for $800,000. It requires written exercise delivered to owner's attorney by certified mail and received by June 30, with a $20,000 option-exercise deposit.

Tenant mails an email July 1 without payment.

Best analysis: The response does not follow the stated time, method or payment terms. The agent should not announce that equity will excuse the defects. That is a legal question for counsel.

Option fee versus purchase deposit

An option fee pays for the option right. A purchase deposit is part of the price or secures duties after the purchase contract exists. The agreement can credit the option fee toward price, make it nonrefundable or provide another treatment. Resist the urge to assume.

Option versus right of first refusal

An option lets its holder choose to purchase on fixed or ascertainable terms during the option period.

A right of first refusal generally becomes exercisable only after owner decides to sell or receives an offer triggering the right. It gives the holder a chance to match or accept the qualifying terms defined by the agreement.

Part 4: the installment land contract

An installment land contract, sometimes called a contract for deed or land contract, lets buyer pay the purchase price over time while seller keeps legal title until the agreed payment or performance point.

It is not simply a long closing date. Buyer may take possession and assume substantial ownership burdens while legal title remains with seller.

Equitable title

Cloke and Lambert explain that execution of an installment purchase contract and part payment can give the contract vendee equitable title and an equitable lien for payments made.

This means the buyer's interest is more than an ordinary tenant's right of possession. Seller's retained legal title functions as security for payment under the agreement.

Core terms need careful drafting

An installment contract should address:

• purchase price and initial payment
• installment amount, interest and amortization
• maturity or balloon payment
• possession date
• taxes, assessments and utilities
• insurance
• repairs and improvements
• title standard and deed delivery
• existing mortgages and new liens
• recording
• late payment and cure
• default and lawful enforcement process
• casualty and condemnation
• assignment

The arrangement can involve mortgage, lending, consumer-protection, tax, recording and foreclosure issues beyond a normal short-term contract of sale.

Default is not automatically an eviction problem

Because buyer can hold equitable title, seller may not be able to treat buyer as an ordinary month-to-month tenant and simply cancel the interest. New York decisions recognize that proper foreclosure proceedings can be required to divest the purchaser's equitable title.

The remedy depends on the contract and facts. This is a strong attorney-boundary question.

Existing mortgage risk

If seller's property remains subject to a mortgage, the installment arrangement may create due-on-sale, payment, priority and foreclosure risk. Buyer can make payments faithfully yet face harm if seller fails to pay a senior lender.

Attorneys should evaluate title, escrow, payment verification, recording and lender consent. A salesperson should not design a workaround.

Installment contract versus purchase-money mortgage

Both can finance seller's sale. Their title structure is different.

Part 5: the attorney boundary for New York licensees

New York Judiciary Law restricts the practice of law by people who are not admitted attorneys. Real estate licensure does not create a general power to draft contracts or give legal advice.

The Department of State's Legal Memorandum LI04 applies Duncan & Hill and draws a narrow practical boundary.

What limited form assistance may be allowed?

The DOS memorandum describes two ways a broker or salesperson can stay within the narrow boundary when using a simple fill-in-the-blanks purchase and sale form:

1. include a condition making the contract subject to approval by each party's attorney, or
2. use a fill-in-the-blanks form approved by a joint committee of the local bar association and realtors association

The licensee may fill nonlegal factual provisions such as names, date and place of closing, property description and consideration. The licensee may not develop legal terms.

If a licensee adds provisions to an approved contract, DOS says the entire contract must be subject to and conditioned on review and approval by each party's attorney. The licensee also may not charge a separate contract-preparation fee or share an attorney's preparation or review fee.

This is limited risk guidance, not a general drafting license. Brokerage policy may be stricter, and local approved forms differ.

What crosses the line?

A licensee should not:

• create a custom mortgage contingency
• draft an installment land contract
• devise detailed seller-financing or mortgage terms
• choose a remedy for default
• write a legal release, option, easement or right of first refusal
• interpret title objections or advise that title is marketable
• tell a party a binder is definitely enforceable or void
• modify an attorney's clause without authorization
• charge a separate contract-preparation fee

In Duncan & Hill, detailed mortgage terms devised by the broker were a central reason DOS found unauthorized practice and untrustworthiness.

Why attorney approval must be bilateral

Moran v Erk explains that making the agreement subject to approval of attorneys for both contracting parties helps prevent unauthorized practice. The Court of Appeals also held that an unqualified attorney-approval contingency allows an attorney to disapprove for any reason or no stated reason unless the contract limits that discretion.

That is different from a clause requiring “reasonable” approval or approval only on stated legal grounds. Exact wording matters.

“Consult an attorney” is not always enough

A recommendation to consult counsel does not turn unauthorized custom drafting into lawful brokerage. The form, scope of blanks, bilateral approval condition, absence of separate fee and licensee's conduct all matter under the DOS guidance.

A safe transaction workflow for a salesperson

1. Collect business terms. Ask the client for price, financing, timing, inclusions and other authorized facts.
2. Use approved systems. Follow the supervising broker's forms and submission procedure.
3. Label the stage accurately. Distinguish proposed, countered, accepted and fully executed.
4. Do not predict enforceability. Send questions about legal effect to counsel.
5. Transmit promptly. Deliver offers, counteroffers, deposits and disclosures through the required channels.
6. Document changes. Record who authorized each business-term revision.
7. Escalate custom language. An option, land contract, unusual contingency or remedy belongs with an attorney.

Eight exam-style scenarios

Scenario 1: asking-price message

Buyer messages, “I might pay asking. Is seller flexible on closing?”

Answer: This looks like negotiation, not a definite offer capable of immediate acceptance.

Scenario 2: conditional response

Seller signs buyer's offer but changes the closing date.

Answer: The changed term ordinarily makes seller's response a counteroffer, not an unconditional acceptance.

Scenario 3: nonbinding deal sheet

Both sides approve a deal sheet saying no party is bound until attorneys negotiate and parties sign a formal contract.

Answer: The document expresses business agreement while reserving legal commitment.

Scenario 4: complete binder

A signed binder identifies parties and property, states price and payment terms, resolves material conditions and says it binds now.

Answer: It may be enforceable despite plans for a longer document. The title “binder” does not defeat present intent.

Scenario 5: late option exercise

Option expires June 30. Holder sends exercise July 1.

Answer: Options generally require strict and timely exercise. Do not apply ordinary flexible-closing rules.

Scenario 6: option holder does nothing

Optionee pays for a 60-day option but decides not to buy.

Answer: Optionee had a right, not a duty, to exercise. Fee treatment depends on the option agreement.

Scenario 7: installment buyer default

Buyer has occupied for years and made substantial land-contract payments. Seller changes locks after one late payment.

Answer: Buyer may hold equitable title, and lawful enforcement can require foreclosure. This is not automatically an ordinary landlord-tenant removal.

Scenario 8: salesperson drafts protection

Buyer asks salesperson to write a custom clause returning all payments if buyer's business income falls.

Answer: The licensee should document the requested business concern and refer clause drafting to the attorneys and supervising broker.

Misconceptions to remove

“An accepted offer is always a final contract”

No. Read the document, signatures, essential terms and conditions about later contract execution or attorney approval.

“A binder is never binding”

No. A complete, properly signed binder showing present intent can bind. An incomplete agreement to agree does not.

“Paying a binder deposit makes the sale enforceable”

No. Payment does not supply missing essential terms or intent.

“An option is the same as a sale contract”

No. The option gives a power to create the bilateral purchase contract through proper exercise.

“Option deadlines work like on-or-about closings”

No. Time is generally of the essence in an option to purchase real property.

“An installment buyer is just a tenant until the deed”

No. A valid installment contract and payment can give buyer equitable title and an equitable lien.

“A salesperson can draft if the client asks”

No. Client consent does not expand a licensee's legal authority.

Frequently asked questions

Is a New York real estate offer legally binding?

An unaccepted offer is a proposal. Once accepted, it can form a contract if the writing, essential terms, signatures, intent and conditions satisfy New York law. Many residential deal sheets expressly postpone commitment until a formal contract is signed.

Is a New York real estate binder binding?

It can be. The court looks at identification of parties and property, essential terms, subscription and present intent. The document's label is not decisive.

Can a seller revoke an offer after creating an option?

The optionor must keep the offer open during a valid option period according to its terms. A qualifying signed written irrevocable offer is not invalid merely for lack of consideration under General Obligations Law section 5-1109.

Does an option buyer have to purchase?

No. An option gives a right to buy, not an obligation to exercise. Once properly exercised, the resulting purchase contract creates bilateral duties.

Is an option exercise deadline strict in New York?

Generally yes. New York decisions require exercise according to the option's time, notice, delivery and payment terms. Waiver or rare equitable issues are questions for attorneys.

Who owns property during a New York installment land contract?

Seller retains legal title under the arrangement, while execution and part payment can give buyer equitable title and an equitable lien. The exact contract and transaction facts control possession and responsibilities.

Can a seller evict an installment buyer after default?

Not automatically as an ordinary tenant. Because the buyer can hold equitable title, proper foreclosure proceedings may be required. Counsel should evaluate the agreement and remedy.

Can a New York salesperson fill in a purchase contract?

Only within the narrow DOS guidance for simple fill-in forms. The licensee must stay with factual, nonlegal provisions, use the applicable attorney-approval or joint-approved-form protection, and charge no separate drafting fee. Brokerage policy may impose tighter limits.

Can a salesperson draft a binder or option?

Drafting language that determines enforceability, remedies or property rights presents unauthorized-practice risk. Use attorney-prepared and brokerage-approved documents and send custom terms to counsel.

Does attorney review mean an attorney must give a reason for disapproval?

Under Moran, an unqualified attorney-approval contingency can permit disapproval for any reason or no stated reason. Different wording can create different limits, so the actual clause controls.
