In the Davis v. Jacoby case brief, the California Supreme Court held in 1934 that an ambiguous offer is presumed to invite a return promise rather than completed performance, making the resulting contract bilateral and binding the moment acceptance is dispatched.1Supreme Court of California. Davis v. Jacoby That classification let a Canadian couple enforce a promised inheritance even though the offeror died before they arrived to perform their side of the bargain.
Facts
Mrs. Davis was the niece of Mrs. Whitehead, and the two couples had stayed close despite living far apart. In the spring of 1931, Mr. Whitehead was in trouble. His wife’s health was failing, his own eyesight was going, and business associates had taken advantage of his condition. He wrote a series of increasingly desperate letters to Mr. Davis in Canada.1Supreme Court of California. Davis v. Jacoby
On April 12, 1931, Mr. Whitehead made a specific proposal: if the Davises would come to California to care for Mrs. Whitehead and help him with his business affairs, they would inherit his entire estate, which he estimated was still worth about $150,000. Two days later, on April 14, the Davises mailed a letter accepting the offer and began preparing to move.1Supreme Court of California. Davis v. Jacoby
On April 22, 1931, before the Davises could arrive, Mr. Whitehead took his own life. The Davises traveled to California at once. Mrs. Davis cared for her aunt daily until Mrs. Whitehead died on May 30, 1931. The trial court found that Mrs. Davis had nursed her aunt “as a natural daughter would have done toward and for her mother.”1Supreme Court of California. Davis v. Jacoby When the Davises sought the promised inheritance, Mr. Whitehead’s will did not reflect the agreement. They sued for specific performance of the contract to make a will.
Issue
Was Mr. Whitehead’s April 12 letter an offer for a unilateral contract, which the Davises could accept only by completing the requested caregiving, or an offer for a bilateral contract, which they could accept by promising to come?
The classification was dispositive. A unilateral contract requires performance, not words; until the offeree performs, the offeror has no obligation and can revoke, and an offeror’s death operates as a revocation.2Cornell Law Institute. Unilateral Contract If the offer was unilateral, Mr. Whitehead’s death on April 22 ended it before the Davises could finish performing. A bilateral contract, by contrast, binds both sides the moment promises are exchanged.3Cornell Law Institute. Bilateral Contract Under that reading, the Davises’ April 14 letter had already locked the deal in place.
Holding
The California Supreme Court reversed the trial court, which had refused relief, and held that the offer was for a bilateral contract. Acceptance occurred when the Davises mailed their letter on April 14, so Mr. Whitehead’s death eight days later did not terminate the agreement. The court directed the trial court to enter judgment for the Davises “as prayed for,” granting specific performance.1Supreme Court of California. Davis v. Jacoby
Reasoning
The justices read Mr. Whitehead’s correspondence closely. His letters sought an immediate commitment, not just eventual action. He wanted someone he could “depend on,” someone who would promise to come to his aid. The Davises’ April 14 letter gave him exactly that.1Supreme Court of California. Davis v. Jacoby
The court also treated the Davises’ conduct as consistent with an already-formed contract. They closed their affairs in Canada, traveled across the continent, and Mrs. Davis provided the promised care. Words and actions together confirmed a bilateral exchange of promises.
Two doctrinal points did the heavy lifting. First, the mailbox rule: the court held the contract formed when the Davises mailed their acceptance, not when Mr. Whitehead received it. That timing sidestepped any factual question about whether he ever read the letter before his death. Second, the bilateral presumption: because Mr. Whitehead’s letters were informal and did not spell out how he wanted to be accepted, the court applied the default rule then set out in Section 31 of the original Restatement of Contracts, which treated an ambiguous offer as inviting a return promise.4Open Casebook. Contracts: Cases and Materials – Unilateral vs. Bilateral Contracts – Manufactured Difficulties Introduction
On remedy, the court granted specific performance rather than money damages. That remedy is reserved for situations where money would not adequately compensate the injured party, and a promise to leave someone an entire estate fits, because the property is unique and its full value is difficult to reduce to a damages formula. The estate had to honor the deal made in the April 12 letter regardless of what Mr. Whitehead’s actual will said.
Rule
The rule Davis v. Jacoby is cited for: when an offer is ambiguous about the required mode of acceptance, courts presume it is an offer for a bilateral contract, accepted by a return promise. Acceptance by mail takes effect on dispatch, and once given, the contract binds both parties even if the offeror later dies or attempts to revoke.
How the Rule Has Evolved
The Restatement (Second) of Contracts replaced the rigid bilateral presumption with a more flexible rule. Section 32 provides that when an offer is ambiguous, the offeree may accept either by making a promise or by beginning performance, at the offeree’s option.5Open Casebook. Restatement (Second) of Contracts 32 – Invitation of Promise or Performance The Davises still would have won under this rule; their written promise qualified as valid acceptance.
The Restatement Second also softened the harsh unilateral-contract result the Davis court worried about. Section 45 creates an option contract once the offeree begins the requested performance, barring revocation and giving the offeree a reasonable time to finish. Section 62 provides that where an offer allows acceptance by either promise or performance, beginning performance operates as an acceptance and carries an implied promise to complete.6H2O. R2K 62 – cmts. a, b, d
For sales of goods, UCC Section 2-206 takes a parallel approach, permitting acceptance “in any manner and by any medium reasonable in the circumstances” unless the offer clearly says otherwise.7Legal Information Institute. UCC 2-206 – Offer and Acceptance in Formation of Contract The UCC did not govern the caregiving-for-inheritance arrangement in Davis v. Jacoby, but it reflects the same underlying preference against trapping parties in rigid acceptance categories.
Why the Case Is Studied
Davis v. Jacoby is a staple of first-year contracts courses because it puts a human face on an abstract classification question. A couple gave up their livelihood and crossed a continent based on a promise made in a letter, and the person who made the promise died before they arrived. Whether they collected anything turned entirely on how a court labeled the offer.
The broader takeaway is that courts will work to find a binding agreement when the surrounding circumstances show both parties intended one. The bilateral presumption, the mailbox rule, and the Restatement Second’s expanded acceptance options all pull the same way: contract law favors enforcing deals that real people actually made, even when the paperwork is messy.
