¶1The complaint alleges that one Rohrs and the defendant entered into a contract whereby the defendant agreed and promised to pay to said Rohrs, or to his order, certain sums of money exceeding the *257sum of $500, from time to time, during the course of the erection of two houses in the city of New York; that, prior to the 16th day of November, 1893, the plaintiff made a contract with said Rohrs whereby the plaintiff agreed to do certain work upon the said houses, and the said Rohrs agreed to pay the jfiaintiff a sum of money exceeding the sum of $500; that certain mechanics’ liens had attached to the said premises; that thereupon the plaintiff refused to proceed with the performance of his said agreement between himself and Rohrs, unless the said Rohrs should pay or secure to be paid to the plaintiff the sum of $500; that thereupon the said Rohrs offered to secure the payment of the said sum by executing; and delivering to the plaintiff an order or assignment set forth in the: complaint; that, on the 16th day of November, 1893, said Rohrsmade and delivered to the plaintiff said order or assignment for $500 out of the moneys due or to grow due under the said agree•ment between .the said Rohrs and the. defendant, which order or assignment was in the following words :
“ November 16th, 1893,
“ J. Allen Townsend :
“ Pay to Matthew C. Kervan five hundred dollars on aje when roof is on and cornice up, skylights up and leaders connected with sewer on the two houses on the north side of 108th street, 125 feet east of Fifth avenue, running fifty feet, which you are making the loans on, and deducted out of my enclosure payments.
“FREDERICK ROHRS.”
¶2That thereafter, and on the 17th day of November, 1893, said order or assignment was duly presented and delivered by the plaintiff to the defendant and duly accepted by the defendant, and that “ thereupon the defendant duly promised and agreed with t-lie plaintiff that, if the plaintiff would proceed with the performance of the last-mentioned agreement, the defendant would pay to the plaintiff the said sum of $500 out of moneys then in his hands and then earned or owing under the terms of said agreement between the defendant and said Rohrs, and notwithstanding the existence or filing of said mechanics’ liens and notwithstanding the entry or filing of any liens or judgments thereafter against said Rohrs or said houses.” The complaint further alleges that, relying upon said order *258or assignment and the acceptance thereof- by the defendant,., and the last-mentioned promise and agreement of the defendant, the plaintiff did the work upon said houses called for by the contract with Rohrs, and that the said Rohrs, on or before the 24th day of November, 1893,-had substantially completed all work and substantially furnished all materials necessary to entitle him or his assignees to the said inclosure payments, and that the said inclosnre payments became due and payable; that the said plaintiff demanded of the defendant the .payment of the said sum of.money which the- defendant promised to pay, but subsequently refused to pay.
¶3The answer denies the making of the agreement alleged in the complaint; denies that the defendant accepted any order or assignment drawn upon him' by Rohrs for any sum of money whatever, otherwise than on the express condition that the sum of money in such order or assignment specified'should thereafter become due-from the defendant to said Rohrs; and denies that any suni of money whatever was on or since the 1st day of November, 1893, or ever thereafter became, due or payable from-the defendant to said Rohrs or to his assigns. '■ '
¶4v The plaintiff, to-prove his cause of action, was called as a witness and testified to the agreement between himself and Rohrs; that he received the order, alleged in the complaint from Rohrs, and that the defendant accepted the order. The order in the complaint was introduced in evidence. ■ Annexed to such order was the following:
“Accepted Nov. 17, 1893, and to be paid when enclosure payment is due Frederick Rohrs. ■ •
“ J. ALLEN TOWNSEND.” '
¶5The.plaintiff was then asked'this question : “ Q. Now state what occurred between you and Hr. Townsend at that time— that is, at. the time you presented this paper to him ? ” This was Objected to by the defendant as being part' of the negotiations between the plaintiff- and the defendant leading up to the contract and merged in the’contract. The objection was overruled arid the defendant excepted. -In answer to that question the plaintiff testified that the defendant told him that there were two liens on the building at that time, but that there was money enough to pay the liens 'and his (plaintiff’s) order. ■ “ He said, my order would be- paid anyway; to go on and finish the work. I did so.” 'The plaintiff further testi*259fied on cross-examination that this acceptance that, the defendant signed was the only one that he had ever had; that he went to see the defendant several times before he got the acceptance; that he saw the defendant on the seventeenth of November, when the defendant accepted this order; and that he did not see the defendant again until he finished .the work according to his contract. There was no proof by the plaintiff that Rohrs ever completed his contract with the defendant so as to become entitled to the inclosure payment; the evidence showed that he never did complete the contract.
¶6The court charged the jury that in order for the inclosure payment to become due it was necessary for all liens to be extinguished and all the work done that was required to be done up to that time; that it was conceded that the liens were never extinguished, and that it was claimed on behalf of the defendant that the work was never done, especially in that the leaders were not connected with the sewer; and that, under those circumstances, there would be no payment due on the seventh installment, and that, therefore, the plaintiff’s sole right to recover rested upon whether or not there was a waiver of this performance of the contract on the part of the defendant Townsend. .It was then submitted to the jury to determine whether or not the defendant, at the time he accepted this order, told the plaintiff that it would be paid whether the liens were withdrawn or extinguished, or whether they were not; and they were instructed that if they believed the defendant said this to the plaintiff at the time of the acceptance of the order there was a waiver, and that if they should find that there was a waiver they should find ■a verdict in favor of the plaintiff. There was no evidence of any waiver after the acceptance of the order. The plaintiff expressly testified that he did not see the defendant from the time of the - acceptance of the order until after liis work was completed. The obligation of the acceptance'of the order to pay money is an engagement to the payee or other lawful holder of the bill to pay the same when it becomes due according to the terms of the acceptance. (Hoffman & Co. v. Bank of Milwaukee, 12 Wall. 181; 4 Am. & Eng. Ency. of Law [2d ed.], 201.) An acceptance may be in writing or oral, but when it is conditional the acceptor is only liable upon the happening of the condition, and the terms of an acceptance in writing cannot be varied by a contemporaneous parol agreement *260(Daniel Neg, Inst. § 517, and cases cited'; 4 Am, & Eng. Ency. of Law [2d ed.], 214), and the liability of the acceptor to the'holder is, according to the terms of his undertaking, completed by'the assent of the holder. (4 Am. & Eng. Ency. of Law [2d ed.], 227.)
¶7The contract sued on is in writing..'It 'is not ambiguous. It expresses fully the obligation assumed by the defendant, and must be held to fully state the contract between the parties. By it Rohrs, who had made a contract with the .defendant and who, upon the ■ performance of that contract, would be entitled to. receive from the defendant a sum- of money, requested the defendant • to pay to the ■ plaintiff §500' when certain work upon the buildings had' been completed by the plaintiff and to deduct it out of the inclosure payment, which was the seventh installment Under the contract between the defendant and Róhrs. The order on its face was payable only upon the inclosure:payment being "due to- Rbhrs, It Was-not to be. paid out of any money due from the defendant to' Rohrs, but was conditioned upon the particular payment becoming due, and it was held by the court below that that payment never did'become due. "When that order was presented to the defendant for acceptance he reduced to writing the obligation which he assumed and delivered it to the plaintiff. That obligation was an agreement to pay to the plaintiff a sum of money when the inclosu-re payment was due to Rohrs. It followed the terms of the order upon him, limiting his liability to a, payment out of a particular fund when that particular fund was payable; and neither upon the order as it stood, nor upon its conditional acceptance by the defendant, was the plaintiff entitled ■ to recover from the defendant any sum of money, except ‘upon proof that thecondition upon 'which that payment was to be made had been complied with and that this in closure payment was due. (4 Am. & Eng. Ency. of Law [2d ed.], 229.) We have the contract made-.by the defendant which expressed his liability ; the acceptance by the plaintiff of .this contract as the- liability which -defendant assumed to the plaintiff,, and unless we are prepared' to- absolutely abrogate the rulé that all prior negotiations must. be deemed merged in the Writing and that the writing must be construed as containing the-contract as actually made, the liability of ■ the defendant must be-restricted, to that which is expressly imposed upon Mm hy the writing-signed by him and which became the contract between .the par*261ties. This rule was recognized by the court below, and we think the court correctly charged that the plaintiff could not recover unless he proved a waiver of this condition upon which his liability depended.
¶8. In this case the evidence of the waiver was confined to conversations between the plaintiff and the defendant prior to or cotemporaneous with the execution of the written agreement, and consisted of an alleged promise by the defendant to pay to the plaintiff the sum called for by the order, whether any money was due to Rohrs or not. It is not alleged that by any word or act of the defendant, after the execution of the writing, the plaintiff was induced to proceed with his work. The waiver was sought to be proved by con-' versations had before the writing was executed, before any condition had been imposed that could be waived. A waiver is defined by Bouvier’s Law Dictionary to be “ the relinguishment or refusal to accept of a right; ” and in 28 American and English Encyclopaedia of Law (p. 526), “ the intentional relinquishment of a known right.” The facts as established by the verdict of the jury in this case show that when the plaintiff took the order to the defendant he had a discussion with the defendant, during which the defendant said that the plaintiff would be paid anyway, whether liens existed or not, or whether this inclosure payment became due or not; that" after-wards, when requested to' reduce the obligation to writing, he did so; the writing, however, restricted his obligation to pay out of a certain specific fund when it should become due and payable. As before stated, the writing must be construed to be the final contract entered into between the parties, all the verbal conversations which led up to it being merged in this writing. These verbal statements, made by either of the parties prior to the execution of the writing, could no more be held to be a waiver of a condition inserted in the writing for the defendant’s benefit than they could be held to prove a modification of the "writing as made. It would be as much a violation of the rule before referred to, to allow an oral statement, made prior to or at the time of the execution of a writing, to prove a waiver of conditions imposed by the writing, as to allow such oral statement to vary the contract. The writing must be held to express the agreement between the parties when it was made, and nothing that was said prior to the making of the agreement is compe*262tent to prove an agreement different from that expressed, or is competent to prove that the parties were not to be bound by the terms and conditions of the writing.
¶9What is meant by a waiver is well expressed in the case of Brady v. Cassidy, which was twice before the Court of Appeals. On the first appeal (104 N. Y. 154) the contract was proved, by which the plaintiffs agreed to sell to the defendants certain manufactured stock “ now on hand at foundry and storerooms ” at a fixed price. The plaintiffs sued to recover for the goods sold and delivered under.this contract, and offered evidence of the negotiations or statements made ■ at the time the bill of sale was executed, to determine the meaning of the language used in the contract in the light of the circumstances. It was held that the contract was plain and unambiguous as to its language, and was susceptible of but one construction; that the court was bound to construe the contiact and not leave it to the jury, and that the testimony as to the prior negotiations was not competent to modify or alter the agreement between the parties.
¶10On the case going back for a new trial the-plaintiffs were allowed to-amend their complaint by inserting allegations that the defendants had received all of the goods which were spoken of in' the inventory, and which did not. include certain omitted goods, and accepted and-appropriated the inventory goods without intimating to the plaintiffs-■that' they were received or accepted with any -conditions whatever, and without- any notice or intimation to the plaintiffs that they should not thereby consent to become liable to pay for the articles'so-delivered and accepted, unless the other articles were also received ; and that the defendants waived the condition that all the goods included iii the agreement and on hand' at the time of its execution should be delivered before they should become liable to pay the contract price for the part-that actually was delivered. Upon the case coming on to be tried upon the amended pleadings, the jury found that there was such' a waiver, and the court on the second- appeal (145 N. Y. 180) said: “ The evidence given on the part of the plaintiffs, if believed by the jury, was sufficient to constitute a waiver by the defendants of the full performance of the contract,-by the delivery of all the goods included in its terms, and-it was sufficient to justify-the jury in. finding for the plaintiffs in the amount of the contract price for all the goods actually delivered, deducting there-; *263from the defendants’ damages resulting from the failure to deliver the balance.” The evidence that was in that case admitted and received were the acts of the defendants after the execution of the contract. The evidence was not received to show that the contract covered a less quantity of goods than was stated, nor were the jury permitted to say whether the contract embraced the omitted goods. The court held that it did, and that the defendants would be entitled under the counterclaim to the damages sustained, because of the failure of the plaintiffs to- deliver the omitted goods. But there was evidence to go to the jury as to whether or not the acts of the defendants in receiving the goods which were actually delivered, subject to the execution of the contract, was a waiver by the defendants of their right to receive all of the goods mentioned in the contract before paying for any of them. It was not-claimed in that case that the statements of the defendants made at the time of the execution of the cont/ract were admissible to prove the waiver•, and' it was expressly held that such statements were not admissible any more than to vary the contract as made, or to show that the construction of the contract should be different from that which the words used plainly imported. But the plaintiffs were allowed to prove that acts of the defendants subsequent to the execution of the contract operted as a waiver of the condition implied by the contract, viz., that all goods should be delivered before there should be any liability for the payment of a portion. Applying this rule to the case at bar, no waiver was alleged in the complaint, nor was there evidence of any waiver. The plaintiff alleged a contract made by the defendant which he failed to prove. . On the contrary, the evidence proved conclusively. that no such contract was made, and no act of the defendant after the making of the contract was alleged to prove any waiver on his part of the conditions imposed by the contract.
¶11In the case of Stone v. Cohen (4 App. Div. 176) the recovery was sustained upon a new promise .by the defendant’s testator after the order had been given, and upon which the plaintiff’s assignor was induced to do the work. The court, after mentioning a conversation made at the time of the execution of the acceptance of the order, to the effect that the defendant’s testator would see the plaintiff’s assignor paid, calls attention to subsequent conversations between the plaintiff’s assignor and the defendant’s testator to induce the plaintiff’s *264assignor to go on and finish the work ; that he would see Burke (plaintiff’s assignor) paid. The defendant’s testator said : “ Never mind the liens; go ahead and finish up and I will pay you; my word is as good as that paper.” The court held that the subsequent conversations and promises by which the plaintiff was induced to proceed with the work was evidence showing a waiver on the part of the ■defendant’s testator of any right that he might have had to insist upon the provisions of the contract respecting liens. Stress was laid all through the opinion upon these subsequent conversations acted on by the plaintiff as evidence of the waiver of the condition which was valid when the contract was made, and which justified a verdict of the jury in finding that the condition was waived.
¶12The alleged promise of the defendant to pay the amount of the order after the work was done was without consideration, and could not be enforced either as a new contract or as a waiver of the condition. ■ It wras a mere nuchom pactum.
¶13We think that in this case, therefore,-the evidence of the conversations between the plaintiff and the defendant, at the timé the order was accepted, was not competent to prove' either a modification of the agreement or the waiver of the condition imposed by the agreement, and that the plaintiff failed to prove the cause of action .■alleged in his complaint. ■ For that reason the judgment is reversed and a. new trial ordered, with costs to the appellant to abide the -event.
¶14Van Brunt, P. J., and Barrett, J., concurred; O’Brien and Rumsey, JJ., dissented.
¶15In 1893 one Rohrs was erecting buildings on certain lots owned by him in the city of New York, pursuant to a building loan contract between him and the' defendant. The plaintiff was to furnish labor and materials on the building for Rohrs. The building loan agreement provided that no advance or payment should be required while there were any mechanics’ liens or judgments affecting the bouses, and that the last payment should be due when the buildings should be inclosed, roofs on and tinned, fronts up and cornices set, skylights and copings on and the leaders up, and connections made with the sewer.
¶16*265The plaintiff alleges that Rohr? offered to secure the payment of $500 which was due him by executing and delivering an order, which he subsequently did, in the following form:
“November 16¿A, 1893.
“ J. Allen Townsend :
“ Pay to Matthew O. Kervan five hundred dollars on °jc when roof is on and cornice up, skylights up and leaders connected with sewer on the two houses … which you. are making the loans on, and deducted out of my enclosure payments.
“FREDERICK ROHRS.”
¶17The plaintiff further alleges that thereafter the order was presented and delivered to the defendant by him and duly accepted, with full knowledge that certain mechanics’ liens had been filed, “ and thereupon the defendant duly promised and agreed with the plaintiff that if the plaintiff would proceed with the performance of the last-mentioned agreement the defendant would pay to the plaintiff the said sum of five hundred dollars out of moneys then in his hands, and then earned or owing under the terms of said agreement between the defendant and said Rohrs, and notwithstanding the existence or filing of said mechanics’ liens, and notwithstanding the entry or filing of any liens or judgments thereafter against said Rohrs or said houses; ” and that, relying upon said order or assignment and the acceptance thereof by the defendant, and the last-mentioned promise and agreement of the defendant, the plaintiff put the roof on said houses and the cornices and skylights and leaders up, and the leaders were connected with the sewers of said two houses, and that the said Frederick Rohrs had substantially completed all work and substantially furnished all materials necessary to entitle him or his assignees to the said inclosure payments.
¶18The defendant denied that he had entered into any agreement other than that contained in the written acceptance, and alleged that the work was not substantially completed, and that the connection was not made between the leaders and the sewer. These issues were litigated upon the trial and resulted in a verdict for the plaintiff, and it is from the judgment entered thereon that this appeal is taken.
¶19*266In the. chárge of the learned judge, to which no .exception was taken, the plaintiff’s right to recover was placed upon the ground that he was bound' to show that the defendant waived the-conditions with -respect to the existence of mechanics’ liens which would be sufficient to defeat the- right of Rohrs to the in closure payment. As therein said: “ This acceptance (referring to the written order) is one of those which,, on the face -of it, would become due. and payable only upon the- completion of work, entitling the builder to .the * • … ‘ enclosure payment.’ In order for that, to become dye, it was necessary for all liens- to be extinguished and all the work dime that was required to be done up .to that time. … ■ The plaintiff’s sole right to recover in this Case rests upon- whether or not there was a waiver of this performance of this contract on the part of the defendant Townsend.”- ■
¶20As there was no request to go to the jury upon the other issue as to performance, both sides having agreed to the view taken by the learned trial judge, that the question of waiver was the only one to be determined, and there being conflicting evidence upon this, we would not be justified in interfering with the verdict if based upon competent evidence. As thus regarded, the case,, in many respects, is similar to that of Stone v. Cohen (4 App.. Div. 175), an examination of which will show -that the facts here proven bring it directly within the principles of ■ that case ; and if there were nothing more we' might well rest our affirmance upon that authority. It is insisted, however, that the distinction between the two cases rests in- the fact that there a waiver was proven by conversations- occurring aftei the acceptance of the order, while in the case at bar the .conversations-relating to the waiver were prior to or contemporaneous with the acceptance of the written order, and, therefore, were incompetent under the rule of law that parol evidence is inadmissible to' contradict the terms of the written acceptance. This distinction does not appear in the opinion as reported, because the agreement, which-was held to be sufficient to establish' the waiver, was- proved, by statements which,in the opinion, were said to have been made at the time of the acceptance of the order, and, that being so, the case is precisely like the case at bar and-should control it. It is true, however that an examination of the record in Stone v. Cohen (supra) does disclose the fact that the testimony to establish the waiver was of statements made *267• after the written acceptance. But this does not in any way, as we think, affect the principle, although it may bear upon the weight to be given to-the case of Stone v. Cohen (supra). But, upon well-settled principles, we are clearly of the opinion that the evidence .given in this case to establish the waiver was competent. It must be remembered that the plaintiff’s cause of action here was not solely upon the-written acceptance, but was upon the agreement, which it was said accompanied the acceptance, to the effect that if the plaintiff would proceed with the work the defendant would pay him the sum of $500 out of the money to be earned and owing under the terms-of the agreement with Rohrs, and notwithstanding the existence or filing of any mechanic’s lien against said houses. This was just as much a part of the agreement, as alleged in the complaint, as was the acceptance, and it comes within the thoroughly-settled rule that where the written contract is only a part of an entire agreement, that which stands solely in parol may also be proved, although th.e effect may be to vary or enlarge that portion of the contract which is contained in the written contract. (Chapin v. Dobson, 78 N. Y. 74.).
¶21But in this case there is no necessity of resorting to that rule. The written contract between the parties consisted of the order and the acceptance and of nothing else. The order directed the payment to the plaintiff of $500 “ when roof is on and cornice up, skylights up and leaders connected with sewer.” The acceptance was “to be paid when enclosure payment is due Frederick Rohrs.” • This acceptance was clearly ambiguous, and, to be understood, it was necessary that extrinsic evidence should be given to show when the inclosure payment was due. As between Rohrs and the defendant, the time when that payment was due was established by the written contract which they had entered into. But that was a contract between them only, and one with which the plaintiff had nothing whatever to do. While it was evidence so far as lie was concerned upon the question when the in closure money was due, there was no rule of law which bound or concluded .him in any. way by the contents of the paper in which was contained the contract between Rohrs and the defendant. In his effort to show when the inclosure money was due, he was at liberty to give whatever - evidence he-might be possessed of on the subject, not only the writ- *268- ten contract between the two parties other than himself, but whatever was said to him by the defendant by way of inducing him to believe that the in closure money was due at some other time or under some other circumstances than those stated in the contract between the defendant and Rohrs. The rule that parol evidence cannot be given to contradict or vary a written agreement is limited to the parties' actually contracting with each other by the agreement, and it cannot'be invoked against one who is a stranger to the contract. (1 Greenl, Ev. § 279.) So far as the contract .between Rohrs and the defendant was concerned, the plaintiff was a stranger to it. He was not bound by any of its provisions. The contract, which he made was solely with the defendant, and it is to be construed in the light of what was said between the defendant and himself at the time that it was entered into so far as facts and circumstances may be given to enable the court to construe it. The plaintiff here did not sue alone, as we have pointed out by the allegations of his complaint,' upon the written acceptance, but alleged the facts showing an agreement in connection with the written acceptance, under which the defendant agreed to pay the plaintiff if he would proceed with. the work, whether liens were or were not filed, and that, in reliance thereon, he proceeded and substantially completed the work. Moreover the order was signed with knowledge on the part of both the plaintiff, and the defendant of the existence of mechanics’ liens, and there is force in- the suggestion that there was an implied waiver of that clause, and that the words inserted in the acceptance, “ when enclosure payment is due Frederick Rohrs,” being ambiguous,- are to be read in the light of the conditions then actually existing, and that as thus understood they relate only to the performance of the work on the buildings, and not to the technical terms of the written contract. In other words, the inclosure payment would’ be due when the work was performed, and would be payable provided no liens had been filed, and the signing of the acceptance by the defendant with knowledge of - the existence of liens is. to be considered with reference to the then conditions.
¶22Apart, however, from this, we prefer to place our affirmance upon the fact appearing that the defendant promised and agreed to pay anyway, without regard to any incumbrances on the property, ■ and that, relying upon such promise, the plaintiff went on and substan*269tially completed his work. This was a contract which the defendant was competent to make and. rested on sufficient consideration. It was not embraced in any writing, and whether it be regarded as an independent collateral agreement or a part of the contract not reduced to writing, evidence of it was properly admitted on the trial. (Brady v. Cassidy, 145 N. Y. 171.) .
¶23As there was no other question of substance presented, we think, for the.reasons given, that the judgment -should be affirmed, with costs.
¶24Rumsey, J., concurred.
