v.
C. L. BYRD and wife, Kathleen N. Byrd.
No. 89.
Supreme Court of North Carolina.
February 1, 1980.
*656 Mast, Tew, Nall & Moore by Allen R. Tew, Clayton, for plaintiff-appellee.
Gulley, Barrow & Boxley by Jack P. Gulley, Raleigh, for defendants-appellants.
BROCK, Justice.
We note first that this contract was executed in Virginia, and that the interpretation of a contract is governed by the law of the place where the contract was made. Bundy v. Commercial Credit Corporation, 200 N.C. 511, 516, 157 S.E. 860, 863 (1931); Fast v. Gulley, 271 N.C. 208, 155 S.E.2d 507 (1967). Secondly, the contract on its face provides that in construing the contract the laws of the Commonwealth of Virginia shall be controlling. This Court has held that where parties to a contract have agreed that a given jurisdiction's substantive law shall govern the interpretation of the contract, such a contractual provision will be given effect. Thus by the provisions of this contract, the law of the Commonwealth of Virginia governs our determination of its validity. Tennessee Carolina Transportation, Inc. v. Strick Corporation, 283 N.C. 423, 431, 196 S.E.2d 711, 716 (1973), later app., 286 N.C. 235, 210 S.E.2d 181 (1974).
Defendants argue to this Court that the land sales contract is on its face unconscionable, illusory and not supported by valid consideration as it is in effect totally one sided in favor of the plaintiff Tangle wood Land Company. Defendants rely first on paragraph 12 of the land sales contract which provides as follows:
¶ 12 "Seller reserves the right to convey its interest in the above described premises and its conveyances thereof shall not be a cause for recision. Buyer expressly consents that Seller and its grantees and/or assigns may mortgage said premises and the rights of Seller and Buyer shall be subordinate to the lien of all such mortgages, whether the same shall be given hereinbefore or hereinafter."
It is defendant-appellants' contention that in light of this paragraph they as purchasers could make all payments under the terms of the contract, and receive no interest in the property in return for such payments. Defendant-appellants argue that plaintiff-appellee could have placed a mortgage in any amount on the property and its rights in the property would be subordinate to such a mortgage by the terms of the contract. For the reasons that follow we disagree and hold that the contract is supported *657 by valid consideration and is not unconscionable on its face.
We turn first to the question of the contract's unconscionability. Paragraph 4 of the land sales contract provides that seller retains title to the property as a security interest until receipt of all payments from the buyer. Upon such receipt seller shall "deliver a conveyance of said lot(s) to Buyer consisting of a SPECIAL WARRANTY DEED. . . ." The code of Virginia, Section 55-69, defines a covenant of special warranty as one where: "the grantor has covenanted that he, his heirs and personal representatives will forever warrant and defend such property unto the grantee . . . against the claims and demands of the grantor, and all persons claiming or to claim by, through or under him." See also Pic Construction Company, Inc. v. First Union National Bank, et al., 218 Va. 915, 919, 241 S.E.2d 804, 806 (1978).
Reading paragraph 12 of the contract in light of paragraph 4 it is apparent that plaintiff has retained the right to encumber title to the property so long as it holds said title as security, however upon defendants' final payment plaintiff is contractually obligated to provide defendants with unencumbered title to the property and defend such title against all of those claiming through them as grantors.
If plaintiff acts in good faith and should be unable for good cause to provide clear title as warranted, the defendants as purchasers may bring suit for specific performance or for nominal damages with return of all monies paid with interest. However, if plaintiff as vendor has acted in bad faith in originally undertaking to convey title, or has voluntarily disabled itself from making such a conveyance (i. e., by mortgaging the property subsequent to the original sale to these defendants) it will be liable to the purchasers-defendants for their loss of bargain. This is computed as the market value of the land at the time of the breach with interest from the date of purchase less the original purchase price left unpaid. (NOTE: Subject to the terms of this contract, defendants must pay the full purchase price before they acquire title, thus the purchase price left unpaid would necessarily be zero, and defendants could recover full market value as of date of breach.) Davis v. Beury, 134 Va. 322, 340, 114 S.E. 773, 777-78 (1922); Williams v. Snider, 190 Va. 226, 230, 56 S.E.2d 63, 65 (1949).
We hold that plaintiff's contractual obligation to execute a Special Warranty Deed upon purchasers' final installment payment provides sufficient mutuality of obligation to prevent the contract from being unconscionable.
We now turn to the question of whether or not the contract is supported by valid consideration. The contractual duty on the part of the plaintiff as seller to execute to the defendants as purchasers a Special Warranty Deed upon defendants' payment of the final installment provides sufficient consideration to constitute a valid contract under Virginia law. Midkiff v. Glass, 139 Va. 218, 223-24, 123 S.E. 329, 330 (1924) held that a promise of a seller to convey property in return for a promise by the buyer to pay the unpaid remainder of the purchase price furnishes a valid and sufficient consideration to hold buyer or his estate liable to pay the remainder of the purchase price.
Finally we turn to the question of whether or not this land sales contract is illusory in that there is no enforceable duty on the part of the plaintiff-vendor to actually convey the property to the defendants as purchasers. Defendants argue to this Court that paragraph 6 of the contract when combined with paragraph 12 noted supra renders the contract illusory. We do not agree. In its pertinent part paragraph 6 reads as follows:
"Buyer agrees that in the event of prior sale of said lot(s), this agreement and note shall be cancelled and voided without further liability to either party, except for refund of all payments made hereunder. . . ."
We interpret the words "prior sale" in paragraph 6 of the contract to mean a contract to sell consummated, or a sale consummated, *658 between the seller and another purchaser with reference to the same tract of land prior to the signing of the subject contract. These words, "prior sale", do not refer to a sale or contract to sell to another purchaser entered into after the time of signing the subject contract or at any time during which the subject contract is being complied with by the subject purchaser.
The reason for paragraph 6 being in the contract is readily apparent. The seller had eight or ten authorized salesmen on the premises of the development for the purpose of driving prospective purchasers through the development to select a lot or tract suitable to the prospective purchaser. Obviously two or more prospective purchasers, accompanied by different salesmen, may select the same lot or tract. The salesman with any one prospective purchaser, easily might not be aware of the prior sale of a particular lot or tract within a short span of time by another salesman. Under these circumstances it is conceivable that the same lot or tract could have been the subject of a prior sale without a second salesman's knowledge, and the second salesman in good faith might offer the lot for sale and execute a contract with a second purchaser. Under such circumstances the "prior sale" provided for in paragraph 6 of the contract would permit the seller to refund whatever the second purchaser had paid upon such second sale, or such second contract to sell, and to void the contract and note. This is a reasonable arrangement for the protection of both the seller and the second would be purchaser. At oral argument in this Court counsel for defendant conceded that allowing a period to set a second sale aside in the event of the above noted contingency was the practical application of paragraph 6.
As so interpreted the provisions of paragraph 6 of the contract do not render the agreement illusory.
All of the foregoing arguments were previously rejected by the Court of Appeals in Land Co. v. Wood, 40 N.C.App. 133, 252 S.E.2d 546 (1979). We find also that the land sale contract in this case is valid under Virginia law and therefore we affirm the opinion of the Court of Appeals.
Affirmed.
CARLTON, J., took no part in the consideration or decision of this case.
COPELAND, Justice, dissenting.
I agree with the majority that the decision in this case turns on application of the law of the Commonwealth of Virginia. Under Virginia law,
"`[W]here the consideration for the promise of one party is the promise of the other party, there must be absolute mutuality of engagement, so that each party has the right to hold the other to a positive agreement. Both parties must be bound, or neither is bound.'" Capps v. Capps, 216 Va. 378, 381, 219 S.E.2d 901, 903 (1975), quoting Town of Vinton v. City of Roanoke, 195 Va. 881, 896, 80 S.E.2d 608, 617 (1954); American Agricultural Chemical Co. v. Kennedy, 103 Va. 171, 176, 48 S.E. 868, 870 (1904).
Where a party suing to enforce a contract promise has given no consideration in exchange for that promise, there is no legally binding contract and the contract cannot be enforced. An illusory promise, being not a legally binding promise at all, is not sufficient consideration to make a contract mutually binding and enforceable. Town of Vinton v. City of Roanoke, supra. The point is well stated in Corbin on Contracts § 145 (1963):
"If what appears to be a promise is an illusion, there is no promise; like the mirage of the desert with its vision of flowing water which yet lets the traveller die of thirst, there is nothing there. By the phrase `illusory promise' is meant words in promisory form that promise nothing; they do not purport to put any limitation on the freedom of the alleged promisor, but leave his future action subject to his own future will, just as it would have been had he said no words at all."
The majority holds that plaintiff-seller's promise to execute to the defendants as purchasers a Special Warranty Deed upon *659 defendants' payment of the final installment of the purchase price provides sufficient consideration to constitute a valid contract under Virginia law citing Midkiff v. Glass, 139 Va. 218, 223-24, 123 S.E. 329, 330 (1924).
The case sub judice is distinguishable from Midkiff because of the additional paragraph present in the contract under consideration here which provides as follows:
"6. Buyer agrees that in the event of prior sale of said lot(s), this agreement and note shall be cancelled and voided without further liability to either party, except for refund of all payments made hereunder to Buyer, and to accept the decision of seller without recourse, that said prior sale of lot(s) has been made."
The question is whether the above paragraph makes the plaintiff-seller's promise to sell and to give a Special Warranty Deed after all installments have been paid, an illusory promise so that there is no consideration to support the defendant-buyers' promise to buy. If the seller's promise to sell is in reality an illusory promise, then the plaintiff cannot enforce this contract against the defendants because there are no mutually binding promises and as noted above, under Virginia law, both parties must be bound or neither is bound. Capps v. Capps, supra.
The issue is what is meant by "prior sale of said lot" in paragraph 6 of the contract. Seller-plaintiff urges and the majority decides that it means a sale of the lot prior to the sale of the same lot on the same day to the second buyers. This alleged interpretation is adopted because it is said that the company has many agents in different places selling these lots and a certain lot may be sold twice in the same day. In that event, the second buyer would get a refund of his down payment because of the prior sale.
The majority so construes this paragraph in order to avoid declaring the contract invalid. Even though maintaining the validity of the contract is a laudable goal, our function is to interpret the contract that the parties have written and not to rewrite the contract for them. A new contract cannot be written for the parties under the guise of construction nor can the contract be altered so as to conform it to the court's notion of the contract the parties should have made in view of the surrounding facts and circumstances. Ames v. American National Bank of Portsmouth, 163 Va. 1, 176 S.E. 204 (1934). There is no basis in the contract for the majority's construction. In fact, I believe that the majority's construction ignores the plain English that seller chose in composing paragraph 6. Words are to be given their ordinary meaning unless it is clearly shown a different meaning was intended, id., and no such showing has been made in this case.
The buyer-defendants argued at the trial level, in the Court of Appeals and in this Court (through incorporation in its brief before this Court of its brief in the Court of Appeals) that prior sale means any sale prior to the payment of the last installment. In that event, seller, at the time this contract was entered into, made no binding promise to sell the lot to the defendants. Instead, the seller made only an illusory promise to sell the lot to the defendants if it did not sell to someone else before all installments were paid by the buyers. From the very words of the contract itself, I believe that this is the only correct interpretation of paragraph 6.
I am not unmindful of the rule of contract construction that states that words in promissory form should not be interpreted so as to make them illusory unless the context shows an intent to leave performance subject to the party's future will and desire. Corbin on Contracts § 546 (1963). From the context of paragraphs 4 and 6 of the contract, which the seller prepared, I believe that there is an objective manifestation by the seller of an intent to leave its performance subject to its future will and desire.
This contract was entered into on 5 May 1974 and on that date a $500.00 down payment was made. The first of the sixty installment payments of $135.25 was due over a month later on 19 June 1974. If the *660 term "prior sale" in paragraph 6 was intended to mean a prior sale on the same day as the sale to the buyer-defendants, as the majority holds, then seller, who prepared this contract, should have provided that in the event of a prior sale the down payment would be refunded since that is the sole payment made on the day of the sale. Instead, seller provided for refund of all payments. The question then becomes, what did seller mean by "all payments"?
The contract must be construed as a whole. State Farm Mutual Automobile Insurance Co. v. Justis, 168 Va. 158, 190 S.E. 163 (1937). The intent of the parties must be gathered from the words they have used in the contract. Ames v. American National Bank of Portsmouth, supra. Paragraph 4 of this contract provides that,
"Seller . . . agrees upon receipt of all payments provided herein . . . to record . . . and deliver a conveyance of said Lot(s) to Buyer consisting of a SPECIAL WARRANTY DEED. . . ." (Emphasis added.)
Certainly "all payments" in paragraph 4 means payment of the down payment and all installment payments by the buyers. In my view, the term "all payments" has exactly the same meaning in paragraph 6 that it has in paragraph 4 for the simple reason that the term is used and defined in paragraph 4 and is then used again two paragraphs later in paragraph 6. The term "all payments" determines the true intended length of the time period for a possible "prior sale" as objectively manifested in the contract language construed as a whole. A "prior sale" could be made by the seller at any time prior to payment of the last installment by the buyers in which event seller would refund all of the payments. Therefore, seller made only an illusory promise and the contract is unenforceable. As stated in Corbin on Contracts § 145 (1963):
"Such an illusory promise is neither enforceable against the one making it, nor is it operative as a consideration for a return promise. This is true even though the other promisor in fact bargains for a mere illusory promise in return and gets it."
This same issue was addressed by the Court of Appeals in Tanglewood Land Co. v. Wood, 40 N.C.App. 133, 252 S.E.2d 546 (1979). There Judge (now Justice) Carlton concluded that buyer's argument (that paragraph 6 of the contract made seller's promise to sell merely an illusory promise) was without merit because the buyer could sue for breach of contract and obtain either specific performance or damages.
Before a party can successfully sue for breach of contract and obtain damages or specific performance, there must first be a valid and enforceable contract which has then been breached. When the only consideration to support a promise to buy is an illusory promise to sell then no valid and enforceable contract has ever been entered into because an illusory promise is not sufficient consideration and sufficient consideration is a prerequisite to the formation of the contract. When a party argues that all it received as consideration for its promise was an illusory promise, then that party is asserting a defense to the formation of a contract and thus, the question of breach of that contract is never reached. In the case cited by the Court of Appeals in Tanglewood Land Co. v. Wood, supra in support of its holding on this point, Davis v. Beury, 134 Va. 322, 114 S.E. 773 (1922), there was a valid and enforceable contract between the parties which seller had breached and buyer brought suit for an appropriate remedy.
"If the promisor bargains for some sort of real promise, and receives only an illusion, there is no contract for the reason that the offer has not been accepted [by a binding promise to convey] as well as for the reason that there is no sufficient consideration." Corbin on Contracts § 145 (1963). (Emphasis added.)
Accordingly, I would hold that seller-plaintiff cannot enforce this contract against buyer-defendants because seller gave no binding promise to sell and convey a special warranty deed as consideration for buyers' promise to buy. Since seller made only an illusory promise, no valid contract *661 was ever entered into and the agreement is unenforceable.
