The rule
A private intention to joke does not defeat assent when the recipient actually and reasonably understands the communicated words and conduct as a serious agreement. Read the communication in context to determine whether it manifests commitment or reserves further assent.
Elements
- Communicated words or conduct manifesting agreement.
- An actual understanding of agreement that is reasonable in context.
Exceptions and limits
- A recipient who knows the apparent agreement is a joke cannot rely on its serious outward form alone.
- Communications reserving further assent do not yet create a power of acceptance.
When the issue arises
Put every communication in order. A signed note followed by a claim of joking requires both the recipient’s actual understanding and the communicated facts supporting it, while a price discussion that reserves further assent may never reach the offer stage. Capacity remains separate. Check whether the recipient heard a reservation before relying on the paper, then examine any requested specific performance on its own grounds.
Build the argument from communicated facts
Start with the proposed bargain, then identify the facts the recipient could perceive: the actual words, the surrounding discussion, any revisions, the signatures, and what happened when the writing changed hands. A statement that the price was fair is useful context, but it cannot substitute for analyzing the communication.
Next ask whether the recipient really understood those signals as assent. Lucy v. Zehmer considered both Lucy's actual belief and the reasonableness of that belief. His prompt financing arrangements and title examination supported the first; the extended negotiation and signed document supported the second.
A secret reservation differs from a disclosed joke. If the recipient hears the speaker say that the transaction is a joke before the apparent agreement, the recipient cannot ignore that knowledge merely because the resulting paper looks serious.
What the restaurant agreement established
In Lucy, the paper identified a farm, a price, and a title-examination condition. The court credited evidence of a lengthy discussion and a rewritten agreement signed by both spouses.
The private remark to Mrs. Zehmer that the arrangement was a joke was not intended for Lucy to hear. Those facts supported a serious agreement from his perspective.
The opinion did not stop at formation. It separately rejected incapacity on the evidence of Zehmer's understanding, and then examined whether equity should compel the sale. A student's answer should likewise avoid turning objective assent into an automatic entitlement to specific performance.
A price can be serious without being an offer
In Lonergan, the seller answered questions, identified the property and price, and approved an escrow bank, yet the correspondence still required further assent. The form-letter context and warning of an expected buyer mattered. The recipient lacked a power to complete the bargain merely by saying yes.
Before applying a timing rule to an alleged acceptance, decide whether the earlier communication was an offer at all. This is why an objective-assent analysis must identify the commitment manifested, rather than just ask whether the sender was joking.
A simple fact pattern
Facts. Maya and Dev negotiate a $200 price for an identified garden statue, sign those terms, and arrange collection on Saturday. Dev understands the transaction as a purchase, but Maya later says she privately intended a joke. Analyze assent, assuming no separate formality or capacity problem.
Analysis. Dev actually understood the exchange as a sale, and the negotiated terms, signatures, and collection arrangement support that understanding. Maya identifies no communicated fact that would have alerted him to a joke. Her later account of a private intention therefore does not defeat assent under Lucy's reasoning.
A harder fact pattern
Facts. A boat owner texts a prospective buyer: 'The price I would consider is $9,000. I am checking with another interested buyer tomorrow.' The recipient replies, 'Sold, I accept.' They have not discussed whether the owner is reserving final approval. The recipient believes the boat is theirs.
Analysis. The conditional pricing language and reference to another buyer support a reservation of further assent, much like the correspondence in Lonergan. A contrary argument would need earlier communications showing that the owner had already committed to sell on a $9,000 acceptance. On the facts given, the stronger reading is preliminary negotiation.
Leading cases
Lucy v. Zehmer
A seller's private joke does not defeat a bargain that the buyer actually and reasonably understood as serious. Lucy also shows why formation and entitlement to specific performance are separate questions.
1954Lonergan v. Scolnick
A newspaper ad and a form letter that answer questions about property are invitations to deal, not an offer, so a buyer who says yes cannot create a contract by accepting them.
Compared with nearby doctrines
| Doctrine | How it differs |
|---|---|
| Misunderstanding | Different reasonable meanings raise a separate problem about each party's knowledge. Do not assume that every dispute about private intent is an undisclosed joke. |
| Offer | Objective interpretation determines whether the communication gave the recipient a power of acceptance or reserved another decision. |
| Unilateral mistake | An apparent agreement and a claim for relief from a mistake are distinct inquiries; establish what was communicated before considering avoidance. |
Common exam mistakes
- Concluding that a reasonable outsider's impression is enough even though the actual recipient knew it was a joke.
- Calling every stated price an offer without examining whether further assent was reserved.
- Treating drinking as an automatic answer. Lucy separately examined whether the signer understood the transaction.
- Awarding specific performance immediately after finding assent, without considering the separate equitable issue.
Practice questions
Lena and Omar discuss a kayak sale at a cookout, agree on the kayak and a $300 price, and sign a note stating those terms. Omar believes the sale is serious, although Lena later says she privately intended a joke. Which statement best analyzes assent, assuming no separate defense?
Answer and explanations
Correct answer: C.
Authority: Lucy v. Zehmer: actual and reasonable belief; capacity; equitable relief
- A. Wrong. The issue is the reasonable meaning of communicated conduct, not an unexpressed reservation. The stem gives no fact showing that Omar knew of a joke.
- B. Wrong. Context matters, but a cookout does not automatically nullify negotiated terms and signatures. Explain the actual circumstances rather than using the setting as a categorical rule.
- C. Correct. The facts establish Omar's actual belief and give concrete grounds for its reasonableness. Lucy v. Zehmer treats an undisclosed joke differently from one the recipient knows about.
- D. Wrong. A deposit is not required merely to manifest assent. The question concerns the meaning of the words and conduct, not whether Omar has already paid.

Quick answers
Does a signed paper make a known joke enforceable?
Not simply because it is signed. Knowledge that the speaker is joking is part of the context. Lucy relied on a buyer who actually and reasonably understood a serious sale.
Why did the court discuss financing and title examination in Lucy?
Those acts supported the finding that Lucy actually treated the transaction as a purchase. They supplemented the outward evidence of a serious agreement.
Why analyze an offer before acceptance timing?
A reply can accept only if the earlier communication created that power. Lonergan rejected the supposed offer, so the buyer could not solve the problem merely by arguing that his reply was prompt.
