‘ ‘ One who accepts assignment of a contract which by express terms is made nonassignable, acquires only a cause of action against the assignor.”

“The general rule is that a separate defense should be complete within itself and contain all the averments necessary to answer the entire cause of action set forth in the complaint or such part thereof as is intended to be controverted: Gardner v. McWilliams, 42 Or. 14 (69 Pac. 915); Moore v. Halliday, 43 Or. 243 (72 Pac. 801, 99 Am. St. Rep. 724). In the construction of pleadings as in the interpreting of other writings, the maxim, ‘That is certain which can be rendered certain,’ applies, and where one part of an answer, for the purpose of avoiding reiteration of facts alike applicable to the other parts of the defense, refers to such part where the matter to which attention is thus attracted is sufficiently set forth, the allusion is a compliance with the requirements of the statute that the language employed in an answer shall be concise and without repetition: 1 Ency. Pl. & Pr. 853; Sutherland v. Phelps, 22 Ill. 91.”
¶5The defense in question reads thus in part:
“That subsequent to the making of the contract of sale, set forth in paragraph II of the defendant’s first and separate answer, and prior to the assignment of *140the said contract, which was made by said Eatinger on July 14, 1917, to the Peninsula Security Company, and is set forth in paragraph IY of the defendant’s first and separate answer, the defendant, Peninsula Security Company, called the plaintiff’s attention, on July 12, 1917, to the fact that there was both a first and second mortgage on said premises. … ”
¶6This is matter of inducement leading to the essential part of the second defense, which is grounded in waiver or estoppel, and under the authority of Casner v. Hoskins, 64 Or. 254 (128 Pac. 841, 130 Pac. 55), was sufficiently pleaded. The further contention of the plaintiff is that waiver was not alleged and that the statement in the defense under consideration did not amount to an estoppel. It is true that the word “waiver” is not mentioned in the answer, but it is stated therein:
“That the said plaintiff is estopped from now asserting this provision of the contract of sale against assignment without consent in writing, in this: that pursuant to said plaintiff’s consent and agreement, the defendant Peninsula Security Company, not knowing that consent to the assignment should be first obtained in writing and relying on plaintiff’s consent and agreement, purchased said contract and has made all payments specified by the contract of sale to the mortgagees and the said Peninsula Security Company, relying on said consent'and agreement of the plaintiff, has kept and performed all other terms and conditions of said contract of sale; that it would now prejudice the defendant, Peninsula Security Company’s interests to permit the plaintiff now to assert the clause in the contract of sale against the assignment unless plaintiff’s consent was first obtained in writing.”
¶7' It is not the name given to the matter averred, but the legal effect to be drawn from the facts stated, which gives force to the pleading. The pleader may *141put a wrong label upon Ms statement of Ms cause of action or defense,, yet tbe court will consider tbe pleading according to its legal effect without reference'to the title it bears. It is sometimes difficult to distinguish between estoppel and waiver. The waiver of the terms of a contract may be made the subject of a still further contract between the parties, and in that case as in any other agreement there must be a consideration and subject matter, and the assent of both contracting parties. But, as already shown, the waiver may result from the conduct of the party for whose benefit the stipulation said to have been waived was made in the first instance. The distinction is thus pointed out by Mr. Justice McBride in Mitchell v. Hughes, 80 Or. 574 (157 Pac. 965):
“Where there is no intention to waive, there is no waiver, unless the conduct of the alleged waiver is such as to have misled the waivee to his prejudice. ‘Waiver involves both knowledge and intention; an estoppel may arise when there is no intention to mislead. Waiver depends upon what one himself intends to do; estoppel depends upon what he caused his adversary to do.’ ”
¶8And it is said in 40 Cyc. 261:
“The question of waiver is mainly a question of intention, which lies at the foundation of the doctrine. Waiver must be manifested in some unequivocal manner, and to operate as such it must in all cases be intentional. There can be no waiver unless so intended by one party and so understood by the other, or one party has so acted as to mislead the other and is es-topped thereby.”
¶9The principle is thus stated by Judge Sanborn in Rice v. Fidelity & Deposit Co., 103 Fed. 427, 435 (43 C. C. A. 270, 278):
*142“But a waiver is either the result of au intentional relinquishment of a known right, or an estoppel from enforcing it. To constitute a waiver there must he an intention to relinquish the right, or there must be words or acts calculated to induce the other contracting party to believe and which deceive him into the belief that the holder of the right has abandoned it; and the party deceived must have acted on his belief, so that an assertion of the right will inflict upon him a loss he would not have sustained if its holder had not appeared to relinquish it.”
¶10‘ These excerpts support the doctrine that waiver or estoppel does not necessarily depend upon the affirmative intention of the waivor, but that in the alternative it may be grounded upon his conduct which misleads the other party into doing something which will inure to his own hurt if the waivor is allowed to repudiate the transaction. Thus it seems that waiver and estoppel largely occupy common ground or shade into each other.
¶11
“This is true even though .the agreement or waiver may be in such terms that, taken alone, it would not be required to be in writing. The only ground upon which a party will be bound by such a waiver is that the other party has so governed his conduct by virtue of and relying upon the attempted waiver or alteration that it would be aiding a fraud to permit him to deny its validity.”
¶12*143Hence it is that if in fact the plaintiff, knowing that the company was about to purchase the contract in ignorance of the requirement that his written consent should be obtained, yet said nothing about that provision and afterwards accepted the benefits of the payments which the company made, it would prevent him from now insisting upon that condition, at least without returning the payments of which he enjoyed the benefit. It matters not whether we call it estoppel or waiver, the result is the same.

“Mr. Smith then said he would not discount the contract, but that he would allow us to make payments to the mortgagees, with the understanding that the second mortgage to the Merchants’ National Bank was to be paid off first; and then we were to start making payments on the first mortgage.”
¶15Drinker also testified to having made certain payments on both mortgages. Another witness, Mr. Holbrook, an officer connected with the bank, narrates having arranged for the interview between Drinker and Smith, at which Smith declined to sell'his interest in the property, and that Drinker then said:
“He would go ahead and pay out in accordance with the terms of his contract, and, in order to make certain that the payments would go direct to the mortgagees, he would pay them direct, and he then paid me $20, which was the amount then due us on our mortgage, and I gave him a receipt for it.
*145“Q. Was that with the consent and agreement of Mr. Smith?
“A. It certainly was. He was right there, and consented to it, as far as I conld see. ’ ’
¶16He declares that there was nothing said at that time about the requirement that an assignment should be in writing, and no objection was raised to the receipt of the money by -him.
¶17The plaintiff himself, speaking of the meeting at the bank, after relating that he declined to sell his equity in the property, testified about the conversation as follows:
“He [referring to Drinker] stated something to the effect that if I did hot accept the discount on my equity, that they should continue the payments to the mortgagee, in protection to their interests in the contract, at which I answered I had no option; that is, I couldn’t help myself.
“Q. Was there any agreement between you and Mr. Drinker at that time that this contract should be modified in any respect?
“A. Nothing whatever was said about modifying the contract.”
¶18It further appears from the testimony that after the defendant company had made some payments on the small mortgage, Smith paid the balance remaining due, receiving the benefit of the payments made by the company. He also admits that the sums paid on the larger mortgage were credited on the interest due thereon. The company took the assignment of the contract from Eatinger on the same day of the conversation at the bank.
¶19It is very plain from this testimony that the company did not make the payments as a mere volunteer. While it cannot be excused for not reading the contract carefully,'although Drinker says he looked it over hastily, *146the conduct of Smith, even as narrated by himself, naturally leads to the conclusion that he did not intend to insist upon the enforcement of the condition requiring his written assent to an assignment of the contract. One would readily infer this from his statement that he had no option, and would be led to believe that he assented, albeit unwillingly, to the payments being made by the defendant to protect its interest in the contract. Moreover, he accepted the benefits of the unauthorized assignment, by receiving the credit for the payments made on the mortgages by the defendant company. As we view the testimony, the waiver of this condition on behalf of Smith is established and the company occupies the position of Eatinger, the original party to the contract.
