Opinion
Plaintiff Martin A. Steiner, and his partial assignee, intervener Siddiqui Family Partnership (hereafter collectively referred to as plaintiffs), seek specific performance of a sales agreement with defendant property owner Paul Thexton. Based on language granting Steiner “absolute and sole discretion” to terminate the transaction, the Court of Appeal construed the agreement as an option and further concluded the option was revocable because it was unsupported by consideration. The Court of Appeal *415 also rejected plaintiffs’ claim that promissory estoppel required the agreement’s enforcement. The court therefore upheld the trial court’s refusal to order specific performance of the agreement.
We agree the agreement was an option; however, we conclude sufficient consideration existed to render the option irrevocable. We accordingly reverse the Court of Appeal’s judgment and remand the action for further proceedings. In light of our conclusion, we need not reach the promissory estoppel issue.
I. FACTUAL AND PROCEDURAL BACKGROUND
In 2003, Steiner, a real estate developer, was interested in purchasing and developing several residences on a 10-acre portion of Thexton’s 12.29-acrе parcel of land. 1 County approvals for a parcel split and development permits were required. Thexton had previously rejected an offer from a different party for $750,000 because that party wanted Thexton to obtain the required approval and permits. The written agreement between Steiner and Thexton, prepared by Steiner, provided for Thexton to sell the 10-acre parcel for $500,000 by September 2006 if Steiner decided to purchase the property after pursuing, at his own expense, the county approvals and permits. Paragraph 7 of the “Contingencies” section of the agreement provided Steiner wаs not obliged to do anything and could cancel the transaction at any time at his “absolute and sole discretion . . . .” 2
*416 After Steiner and Thexton signed the agreement on September 4, 2003, 3 Steiner began pursuing the necessary county approvals and, together with his partial assignee Siddiqui, ultimately spent thousands of dollars. 4 In May and August 2004, Thexton cooperated with Steiner’s efforts by signing, among other things, an application to the county planning department for a tentative parcel map. In October 2004, however, Thexton asked the title company to cancel escrow and told Steiner he no longer wanted to sell the property. *417 Steiner nevertheless proceeded with the final hearing of the parcel review committee and apparently obtained approval for a tentative map. Steiner opposed cancelling escrow and filed suit seeking specific performance of the agreement. In his answer, Thexton asserted various defenses, including that the agreement constituted an option unsupported by consideration. 5
Following a bench trial, the trial court entered judgment in favor of Thexton. It concluded the agreement was unenforceable against Thexton “because it is, in effect, an option that is not supported by any consideration.” First, it pointed оut that the agreement bound Thexton to sell the property to Steiner for $500,000 for a period of up to three years while Steiner retained “ ‘absolute and sole discretion’ ” to cancel the transaction. “The unilateral nature of this agreement,” the trial court explained, “is the classic feature of an option.”
Second, in concluding, “[b]ased on the evidence and the language of the contract itself, . . . that the option was not supported by consideration,” the trial court noted no money was paid to Thexton for his grant of the option to purchase the property, nor did he receive any other benefit or thing of value in exchange for the option. 6 The trial court rejected plaintiffs’ claim that the agreement obligated them to expeditiously proceed with the parcel split and that their work and expenses constituted sufficient consideration for the option. The trial court reasoned that the adequacy of consideration is measured as of the time a contract is entered into and pointed out the agreement did not bind plaintiffs to do anything; rather, it gave them the power to terminate the transaction at any time. Finally, the trial court rejected plaintiffs’ claim that, in the absence of consideration for the option, their efforts merited applying the doctrine of promissory estoppel. The Court of Appeal affirmed for the reasons given by the trial court and we granted review.
II. DISCUSSION
We consider whether the agreement was an option and, if so, whether the option was irrevocable because it was supported by sufficient consideration. We conclude, for the following reasons, that the agreement is an irrevocable option. 7
*418 A. The Sales Agreement Constitutes an Option
Plaintiffs contend the Court of Appeal erred when it concluded the sales agreement constituted an option. We disagree. We begin by briefly setting forth the established law concerning what constitutes an option.
As this court explained long ago, “When by the terms of an agreement the owner of property binds himself to sell on specified terms, and leaves it discretionary with the other party to the contract whether he will or will not buy, it constitutes simply an optional contract.”
(Johnson
v.
Clark
(1917)
In the present case, although the agreement was titled “REAL ESTATE PURCHASE CONTRACT,” the label is not dispositive. Rather, we look through the agreement’s form to its substance.
(Mahoney v. San Francisco
(1927)
Moreover, it appears that the term’s broad and express language permitted Steiner to terminate the agreement even if аll contingencies had been satisfied—indeed, Steiner testified at trial that the term gave him the power to terminate the agreement at any time for any reason, including if he had found *419 a better deal. For that reason we reject the notion, advanced by Steiner and various amici curiae, that the agreement should instead be construed as a bilateral contract subject to a contingency. It is true, as amicus curiae California Association of Realtors explains, that a common form of real estate contract binds both parties at the outset (rendering the transaction a bilateral contract) while including a contingency, such as a loan or inspection contingency, that allows one or both parties to withdraw should the contingency fail. However, withdrawal from such a contract is permitted only if the contingency fails. By contrast, the agreement here placed no such constraint on Steiner. Rather, it limited Thexton’s ability to withdraw, but explicitly allowed Steiner to terminate at any time for any reason. 8 Even had the agreement obligated Steiner, as he contends, to move expeditiously to remove the contingencies, we would nonetheless conclude that the “absolute and sole” right to withdraw he enjoyed means the agreement is an option.
We briefly address a number of plaintiffs’ other arguments, finding none persuasive. First, plaintiffs argue that in the event of ambiguity, California law presumes a contract to be bilateral rather than an option.
(Patty
v.
Berryman
(1949)
Third, plaintiffs contend the agreement obliged them to act expeditiously. Even if true, it is irrelevant to whether the agreement constituted an option. Steiner’s unfettеred power to withdraw at any time for any reason overrode any other obligations. Fourth, plaintiffs argue the Court of Appeal should have applied the implied covenant of good faith and fair dealing to narrow the escape clause to give Steiner only a limited power to terminate the agreement. We disagree. While this court has held that all contracts impose a duty of good faith and fair dealing and that the covenant particularly applies when “one party is invested with a discretionary power affecting the rights of another”
(Carma Developers (Cal.), Inc. v. Marathon Development California, Inc.
(1992)
In light of the foregoing reasons, we conclude the Court of Appeal correctly construed the so-called “purchase contract” as an optiоn. We next consider whether the option was irrevocable.
B. Sufficient Consideration Rendered the Option Irrevocable
“An option is transformed into a contract of purchase and sale when there is an unconditional, unqualified acceptance by the optionee of the offer in harmony with the terms of the option and within the time span of the option contract. [Citation.]”
(Erich v.
Granoff(1980)
“[A]n option based on consideration contemplates two separate [contracts], i.e., the option contract itself, which for something of value gives to the optionee the irrevocable right to buy under specified terms and conditions, and the mutually enforceable agreement to buy and sell into which the option ripens after it is exercised. Manifestly, thеn, an irrevocable option based on consideration is a contract . . . .”
(Torlai v. Lee
(1969)
Civil Code section 1605 defines consideration as “[a]ny benefit conferred, or agreed to be conferred, upon the promisor, by any other person, to which the promisor is not lawfully entitled, or any prejudice suffered, or agreed to be suffered, by such person, other than such as he is at the time of consent lawfully bound to suffer, as an inducement to the promisor . . . .” Thus, there are two requirements in order to find consideration. The promisee must confer (or agree to confer) a benefit or must suffer (or agree to suffer)
*421
prejudice. We emphasize either alone is sufficient to constitute consideration; “it is not necessary to the existence of a good consideration that a benefit should be conferred upon the promisor. It is enough that a ‘prejudice be suffered or agreed to be suffered’ by the promisee. [Citation.]”
(Bacon v. Grosse
(1913)
It is not enough, however, to confer a benefit or suffer prejudice for there to be consideration. As we held in
Bard v. Kent, supra,
The lower courts concluded no such consideration supported the option. They reasoned no money was paid for the grant of the option nor did the work performed and expenses incurred by plaintiffs in pursuit of a parcel split benefit Thexton. Citing
O’Connell v. Lampe
(1929)
It is true that Steiner’s promise to undertake the burden and expense of seeking a parcel split may have been illusory at the time the agreement was entered into, given the language of the escape clause. However, there can be no dispute that plaintiffs subsequently undertook substantial steps toward obtaining the parcel split and incurred significant expenses doing so. 10 Among other things, plaintiffs paid for the required civil engineering and surveying for the parcel and spent a number of months applying to the county planning department for a tentative parcel map, рroceeding with the final hearing of the parcel review committee, and obtaining approval of the tentative map. On this record, the only possible conclusion is that Steiner both conferred a bargained-for benefit on Thexton and suffered bargained-for prejudice unaffected by his power to cancel, making up for the initially illusory nature of his promise.
It is undisputed that a parcel split of the 12.29 acres was necessary for Thexton to be able to sell a portion of his land to anyone while still retaining a two-acre parcel for himself to live on. There is also no dispute that Thexton did not want to have to go through the process of obtaining the parcel split himself. Indeed, he had previously rejected an offer of $750,000 for the 10 acres ($250,000 more than Steiner was to pay for the parcel) because that buyer wanted Thexton to obtain the required approval. It is clear then that a critical part of Thexton’s willingness to sell was that Steiner would bear the expense, risk, and burden of seeking the parcel split. Indeed, there is evidence that Thexton told Steiner it was important to him that any interested buyer undertake the process of obtaining the parcel split. Thus, both elements of consideration were present. First, the effort to obtain the parcel split cleаrly conferred a benefit on Thexton and constituted prejudice suffered by plaintiffs. 11 Second, the promise to pursue the split was plainly bargained for and induced Thexton to grant the option. Accordingly, plaintiffs’ part performance cured the illusory nature of their promise. 12
*423
Two cases illustrate the point. In
Burgermeister Brewing Corp.
v.
Bowman
(1964)
In
Kowal
v.
Day
(1971)
In sum, it is true that, where consideration for an agreement consists of an exchange of promises, that one party’s promise is illusory generally means there is no consideration.
(Mattei v. Hopper
(1958)
We address two final points. First, as noted above, the lower courts concluded that the adequacy of consideration is to be determined at the time an agreement is entered into. However, the two cases relied upon are inapplicable here. In both cases, the parties had entered into option contracts for the purchase of real property.
(O’Connell v. Lampe, supra,
Second, we acknowledge that
Prather v. Vasquez
(1958)
In conclusion, we hold plaintiffs’ part performance of their bargained-for promise to seek a parcel split cured the initially illusory nature of the promise and thereby constituted sufficient consideration to render the option irrevocable.
III. DISPOSITION
The judgment of the Court of Appeal is reversed and the case is remanded for further proceedings. 14
George, C. J., Kennard, J., Baxter, J., Werdegar, I., Chin, I., and Corrigan, J., concurred.
Notes
The factual and procedural history is largely taken from the Court of Appeal’s opinion.
The agreement was titled “REAL ESTATE PURCHASE CONTRACT” and stated in part:
“Martin A. Steiner and/or Assignee, hereinafter called ‘Buyer,’ offers to pay to FAS Family Trust, Paul Thexton, hereinafter called ‘Seller,’ the purchase price of Five Hundred Thousand Dollars ($500,000.00) for 10 acres of a 12.29 acre property situated in the County of Sacramento . . . hereinafter called ‘Property’ ....
“TERMS OF SALE:
“1. Upon the Seller’s acceptance escrow shall be opened and $1,000 . . . shall be deposited by Buyer, applicable toward purchase price.
“2. During the escrow term, Seller shall allow Buyer an investigation period to determine the financial feasibility of obtaining a parcel split for development of the Property. Buyer shall have no direct financial obligation to Seller during this investigation period as Buyer will be expending sums on various professional services needed to reach the financial feasibility determination. Buyer hereby warranties that all fees shall be paid for said professional services by Buyer and neither the Seller nor the Property will in any way be obligated or indebted for said services, [ft] ... [ft]
“5. Buyer will pаy for the required civil engineering and surveying for the entire parcel map. Any agency requirements of Seller’s remaining 2.29 acre parcel will be paid by Seller. Any agency requirements for planning, development or entitlement of the 10 acre parcel will be paid by Buyer, [ft] ... [ft]
“10. If any condition herein stated has not been eliminated or satisfied within the time limits and pursuant to the provisions herein, or if, prior to close of escrow, Seller is unable or *416 unwilling to remove any exceptions to the title objected to, and Buyer is unwilling to take title subject thereto, then this Contract shall at the end of the applicable time period, become null and void. HD ... HD
“17. Buyer hereby agrees to purchase the above described Property for the price upon the terms and conditions herein expressed. . . . HD • • • HD
“CONTINGENCIES:
“The Buyer shall have from date of acceptance until the closing of escrow to satisfy or waive the items listed herein below:
“1. Seller is aware that Buyer plans to subdivide, apply for planning entitlements and develop 10 acres from the existing parcel and agrees to cooperate, as needed, with Buyer as Buyer attempts to obtain the necessary permits and authorizations from the various local jurisdictions.
“2. Buyer at his sole option and expense will conduct all necessary investigations, еngineering, architectural and economic feasibility studies as outlined earlier in this Contract.
“3. Both Buyer and Seller understand that Buyer could have substantial investment during this development period.
“4. Buyer shall hereby indemnify and hold Seller harmless for any acts, errors or omissions of Buyer or Buyer’s agents; and Buyer and Buyer’s agent hereby agree that, upon the performance of any test, they will leave the Property in the condition it was in prior to those tests.
“5. By acceptance of this offer, the Seller has granted Buyer and/or Buyer’s agents, the right to enter upon subject Property for the purpose of conducting said tests and investigations.
“6. Buyer shall indemnify and hold Seller harmlеss for any costs associated with Buyer’s investigations. In the event that this contract is terminated prior to the close of escrow, Buyer shall deliver to Seller the originals or copies of all information, reports, tests, [etc.]
“7. It is the intent of Buyer that the time period from execution of this contract until the closing of escrow is the time that will be needed in order to be successful in developing this project. It is expressly understood that the Buyer may, at its absolute and sole discretion during this period, elect not to continue in this transaction and this purchase contract will become null and void.
“CLOSE OF ESCROW:
“Upon successful completion of subdividing the 10 acres from the еxisting parcel, Buyer will pay Seller the balance of the purchase price to escrow and close immediately.
“Buyer will move expeditiously with the parcel split. It is anticipated it will take one to three years, due to existing governmental requirements.
“Buyer will give quarterly reports to Seller as to progress of the parcel split.
“If parcel split is not completed by September 1, 2006 this real estate purchase contract will be cancelled.”
In January 2004, the parties executed an addendum allowing Steiner to purchase up to 10.17 (instead of 10) acres and eliminating several requirements {the original agreement had imposed оn Steiner.
Plaintiffs alleged (and the Court of Appeal assumed without deciding) that they had spent $60,000 on efforts to obtain the parcel split.
Siddiqui, with leave of court, intervened based on Steiner’s partial assignment of his rights.
The agreement required Steiner to pay $1,000 into an escrow account, but the trial court concluded the payment did not constitute consideration.
The interpretation of the agreement is subject to de novo review.
(Parsons v. Bristol Development Co.
(1965)
Thus, bilateral contracts subject to a contingency, which are widely used in real estate transactions, are not affected by our holding.
Indeed, plaintiffs contradict themselves, later arguing “nothing in the Contract suggests that Thexton reserved the right to revoke, withdraw, or terminate his promise to sell the Property to Steiner . . . .”
Plaintiffs completed 75 to 90 percent of the work needed to obtain the parcel split and county approvals and alleged they collectively spent $60,000 in doing so. We have no occasion to consider whether any act, no matter how small, would be sufficient part performance to make an option irrevocable.
As Steiner’s counsel acknowledged at oral argument, the outcome might have been different hаd plaintiffs’ efforts been exclusively in their own interest, such as only securing county approvals to develop the 10-acre parcel.
Although our conclusion is based upon plaintiffs’ part performance of the promise to obtain a parcel split, we also note the agreement required Steiner to deposit $1,000 into escrow, which he did. The trial court concluded the payment did not constitute consideration because Steiner would recover the money if he terminated the agreement; thus, the money did not confer a benefit on Thexton. However, even assuming the trial court’s interpretation of the *423 agreement is accurate, it is not clear its ultimate conclusion is correct. As previously discussed, for consideration to exist it is sufficient that a promisee suffers bargained-for prejudice. By placing the money in escrow, Steiner gave up use of the money for as much as three years. This arguably constituted prejudice to Steiner even if he ultimately got the money back. In light of our conclusion regarding plaintiffs’ part performance, we need not resolve the effect of the escrow payment.
Thus, we reject the contention made by Thexton’s counsel at oral argument that part performance can never constitute consideration for an oрtion. (See also
Kowal v. Day, supra,
Thexton raised a number of affirmative defenses in addition to the ones considered here. Among them were that plaintiffs’ claims are barred by various equitable doctrines and that their claims are barred by the applicable statute of limitations. On remand, the lower courts can consider whether plaintiffs’ claims survive Thexton’s other defenses and, if so, what the appropriate remedy might be. Because the remedy of specific performance is equitable in nature (see, e.g., 13 Witkin, Summary of Cal. Law (10th ed. 2005) Equity, § 24, pp. 312-314), the lower courts can consider whether ordering specific performance is warranted or whether other relief might suffice.
