statement This is a suit by attachment for rent. On December 10,1894, plaintiff leased to the "defendant a ^avm ^w0 hundred acres in Jasper county, the term to begin March 1, 1895, and ending March 1, 1896. Defendant was to pay as rent $70 on September 15, 1895, and $70 on December 1,1895. By the terms of the contract, which was in writing, the lessor reserved in express language a lien on the crops to be raised and no part thereof was to be removed until the rent was paid. As further security for the rent, the defendant executed a chattel mortgage on two horses, worth, according to the evidence, about $60. The grounds of attachment were that defendanthad sold a portion, and was about to dispose of the whole crop, thereby endangering, hindering and *278delaying plaintiff in the collection of its rents. The main defense interposed by plea in abatement, and relied upon, was that in giving the mortgage on the horses it was understood and agreed by lessor and lessee that the lien on the crops should be considered as waived and released.
On a trial of the plea in abatement there was a verdict and judgment for defendant and plaintiff appealed.
to vary written instrument. Because .of the violation of well settled principles of law this judgment can not stand. In securing this result the defendant was erroneously permitted to introduce parol evidence of , L conversations, and of an alleged oral agreement, which he claimed to have had with plaintiff’s agent at the time and before the written contract was entered into — and to the effect that he, the defendant, was not to be bound by the terms thereof. In other words, notwithstanding the parties met together before a justice of the peace and signed and acknowledged the lease and mortgage, in which were incorporated the specific terms of contract, yet defendant was allowed to contradict in part these terms and by parol prove a different agreement to have been entered into at the time. It is clear that this can not be permitted. The lease and mortgage, having been entered into and executed at the same time, and in relation to the same subject-matter, must be construed together and treated as one contract. And as to what were the terms of that contract, it is clear the parties must abide by the contents of the writing. ‘*A party can not be relieved from express and definite conditions voluntarily inserted in a written contract, on the mere ground that at the time of executing the contract verbal conditions were agreed to, contradicting the writing.” 1 Beach, Modern Law of Contracts, sec. 784; Wood v. Murphy, *27947 Mo. App. 539; McDonald v. Wolff, 40 Mo. App. 302.
connmedTonts ?f0*n of!execu" In the lease agreement between these parties it was specifically stipulated that the plaintiff should retain his landlord’s lien on the crop to be grown the leased premises, and by this writing must the rights of these parties be measured, regardless of verbal understandings at or prior thereto. It is not possible under the evidence contained in the record to separate the lease from the mortgage and treat the latter as part of a subsequent independent parol modification of the contract. The defendant’s contention that after the execution of the lease he made an independent and separate contract whereby it was agreed that the chattel mortgage on the two horses should be taken by the plaintiff in lieu, of and in discharge of the landlord’s lien contained in the lease, is unsupported by any substantial evidence. The facts, unquestionably, are that the giving of the mortgage was determined on before even the lease was signed, and the magistrate was directed to prepare it. The proof shows that the justice, who filled up the blanks in the mortgage, was called upon by both parties to advise and direct them in the execution of both instruments, and that the whole matter was done at one and the same time. Whether the lease or mortgage was first signed by the parties is of no consequence, -since it is clear that it was all one transaction.
Parol to vary written: purThe wisdom of this salutary rule — that contemporaneous parol evidence can not be received to contradict or vary the terms of a written con- , ** tract, is made manifest in this case. The testimony given byplaintiff’s agent and by defendant was conflicting in relation to the pretended agreement to waive the landlord’s lien — though *280the agent was corroborated by the justice who prepared the papers and other facts and circumstances attending the execution thereof. The purpose of the rule is then to take away the temptations for perjury, or even to avoid the result of a misunderstanding. “Where parties have reduced their contract to writing, it will be conclusively presumed, in the absence of fraud, accident or mistake, that such writing includes the whole engagement and the extent and manner of the undertaking.” Morgan v. Porter, 103 Mo. 135.
The trial court then erred, in admitting said parol evidence relating to the terms of the contract, and also erred in leaving it to the jury to find that there was a contract different from that embodied in the lease and mortgage. The judgment will therefore be reversed and cause remanded for a new trial.
All concur.
