“Witness our hands this 8th day of August, A. D. 1929.
“-- J. O. Smart Party of First Part.
“-- S. P. Osburn Party of Second ' Part.”
The plaintiff Osburn, the complaining party, alleged that on August 16, 1929, the contract was consummated by him conveying his property as described in the contract to Aurelia Smart, wife of defendant J. O. Smart; that the Smarts on that day executed and delivered deeds to plaintiff to lot 3, block 15, and lot 12, block 13, mentioned in the contract, and at the same time by written transfer assigned the two second vendor’s lien notes mentioned in the contract, representing to plaintiff that said notes were good and would be paid promptly as they became due; that, by reason of the accelerating clauses and the failure to pay the specified installments, plaintiff, on October 16, 1929, elected to and did declare said notes due and payable, and that: “By virtue of the terms of said contract, and by law, plaintiff is entitled to a vendor’s lien upon the property conveyed by plaintiff and described in said contract to defendant Aurelia Smart by reguest of defendant, J. O. Smart, and to a judgment foreclosing said vendor’s lien.”
Plaintiff further alleged that: “By mutual mistake of the parties to said contract, plaintiff paid to defendant J. O. Smart, Four Hundred and Fifty ($450.00) Dollars in cash, when, according to the terms of the contract, said J. O. Smart should have paid $450.00 to plaintiff, and therefore plaintiff is now entitled to recover from defendants J. O. Smart and Aurelia Smart Nine Hundred ($900) Dollars, together with interest at 6% since to wit, August 8th, 1929.” For which he prayed 'judgment with foreclosure of the vendor’s lien.
Smart and wife answered with a general demurrer and a general denial, and specially to the effect that the written contract set out in plaintiff’s petition had been duly executed and the properties delivered as therein provided, and that:
“Said contract represents and is the exact proposition and trade except as to values placed on the properties agreed upon by the plaintiff and the defendant J. O. Smart; that the trade and sale of the property set out in said contract and the terms of said contract were carried out by both the plaintiff and the defendant. * * * That the agreement to trade property or properties as above set out was the proposition upon which the minds of the plaintiff and these defendants met and was the identical trade and proposition intended by both the plaintiff and these defendants, and was the identical trade and proposition that was carried out and consummated by the plaintiff and these defendants on the 16th day of August, 1929. * * *
“The said defendants say that they did not at any time indorse said second lien notes and that they did not at any time guarantee the payment of said notes or any part of same to the plaintiff Osburn and that they did not at any time agree either directly or indirectly that the plaintiff should have a lien on the farm conveyed to the defendants by the plaintiff, to secure said two second vendor’s lien notes. And the said defendants deny specially that the plaintiff is entitled to a lien upon said farm to secure payment of said notes, either by terms of said contract or by law.”
The defendants further specially denied the other claims, aggregating $900, and alleged in substance that the property upon which the notes conveyed to Osburn rested had been examined prior to the trade by Osburn, and was well worth much more than the sums secured by the liens thereon.
The evidence indicates that the case was tried on the theory that by mutual mistake the contract was not as written. It is undisputed that the negotiations which culminated in the execution of the agreement was by a broker, one Borho, acting for both parties; that the parties themselves at no time met or conferred together, but the broker would submit to the respective parties the respective bids, and the contract and conveyances of the properties were signed by the principal parties without having met.
Among other things, it was the contention of the plaintiff that, at the time of the execution of the contract, the negotiating agent, acting for Smart, had declared the notes were good, and that they would be paid, and fur-' ther that he (Osburn) should have a lien upon the properties conveyed by him to Smart to secure the payments of those notes. This testimony was controverted by the defendants, and the case was submitted to a jury on *1076two issues, which, together with the answers thereto, are as follows:
“Was the oral agreement made by Borho with Osburn that Osburn should 'have a lien on the farm to secure the two notes traded Osburn by Smart? Answer: No.
“Was the oral agreement made by Borho with Smart that Osburn should have a lien on the farm to secure the two notes traded Osburn by Smart? Answer: No.”
Upon the verdict so rendered, the court entered judgment that the plaintiff take nothing as against J. O. and Aurelia Smart, and that they go without day and recover their costs; and further entered judgment in favor of the plaintiff against F. D. Turner, who had executed the two second vendor’s lien notes transferred to the plaintiff, and who had been made a party defendant in the suit, but who failed to answer, for the sum of $4,615.90, principal, interest, and attorney’s fees, with interest thereon from the date of the judgment at the rate of 8 per cent, per annum and all costs of suit, etc. The plaintiff, Osburn, excepted to the judgment in favor of the Smarts, and gave due notice of appeal therefrom to this court.
On the submission of this cause, the argument proceeded, in part at least, upon the theory that there was a mutual mistake in the terms of the contract in more than one particular, but the only mistake alleged in the pleadings is that charged by the plaintiff, Osburn, that there was a mistake made in the payment of the $450 to Smart. The concluding clause of the contract is that: “No change or addition in this contract shall be made except in writing signed by both parties and their agents, and no representation as to value, condition or otherwise concerning this property shall be binding on either party or their agents unless embodied herein in writing.”
And we find no change of any kind in the contract embodied in writing and attached thereto. We think, therefore, that the rights of the parties are to be determined by the terms of the contract in the light of the evidence otherwise relevant, to which reference will be made. By a reading of the contract it will be observed that each of the parties was to assume the incumbrances and liens on the property conveyed to him. On lots 3 and 12, conveyed by Smart to Osburn, there was an indebtedness of $4,440, which, by the terms of the contract, Osburn assumed. If this be deducted from $12,168.2S, the agreed value of Smart’s property, it leaves $7,728.28 as the net dr actual value that Smart conveyed to Osburn. The agreed value of Osburn’s property was $8,178.28. Deducting the $7,728.28 conveyed by Smart leaves $450 as the excess value of Osburn’s property. It is clear from the contract as a whole that in the exchange of properties severally conveyed equality of values was intended, and hence it is apparent on the face of the contract that the $450 the contract recites Os-burn paid 'Smart is a patent mistake; that in truth this $450 was due from Smart to Os-burn. This must be held, we think, from the terms of the contract, regardless of the evidence, for the earlier provisions providing equality of values in the exchange of properties control the later recitation of Osburn’s payment to Smart — it being a rule in the construction of contracts that, where there is a conflict or ambiguity in the terms of a contract, the earlier provision will prevail over the latter. See 10 Tex. Tur. pp. 310, 311, § 179, and cases cited.
Proceeding then on the theory that Smart on the date of the execution of the contract was due Osburn $450, which he did not pay, to which must be added the $450 which the evidence shows without dispute Osburn in fact paid Smart upon the exchange of deeds, there is a total sum of $900 that Smart is actually indebted to Osburn in this particular.
In treating the subject of equitable liens, it is said in Story’s Equitable Jurisprudence (14 Ed.) p. 303, § 1163, that: “One of the most common cases in which a court of equity acts upon the ground of implied trusts, in invitum is where a party has received money which he cannot conscientiously withhold from another party. It has been well remarked that the receiving of money which consistently with conscience cannot be retained is in equity sufficient to raise a trust in favor of the party for whom or on whose account it was received. This is the governing principle in all such cases. And therefore whenever any interest arises, the true question is, not whether money has been received by a party of which he could not have compelled the payment, but whether he can now, with a safe conscience, ex aequo et' bono retain it. Illustrations of this doctrine are familiar in cases of money paid by accident, or mistake, or fraud. * * * ”
In the same volume, page 259, § 1622, it is said that: “But there are liens recognized in equity whose existence is not known or obligation enforced at law, and in respect to which Courts of Equity exercise a very large and salutary jurisdiction. In regard to these liens it may be generally stated that they arise from constructive trusts. They are therefore wholly-independent of the possession of the thing to which they are attached as a charge or incumbrance, and they can be enforced only in Courts of Equity. The usual course of enforcing a lien in equity, if not discharged, is by a sale of the property to which it is attached. Of this we have a strong illustration in the well-known doctrine of Courts of Equity, that the vendor of land has a lien on the land for the amount of the purchase-money, not only against the vendee himself, and his heirs and other *1077privies in estate, but also against all subsequent purchasers having notice that the purchase money remains unpaid. To the extent of the lien the vendee becomes a trustee for the vendor; and his heirs and all other persons claiming under them with such notice are treated as in the same predicament.”
In accord with the principles to be gleaned from the quotations made from Story, we conclude that Osburn is entitled to a personal judgment against J. O. Smart for the said $900, together with interest thereon at the rate of 6 per cent, per annum from the 8th day of August, 1929, to secure which Osburn should have the equitable and implied vendor's liens upon the real estate conveyed by him to Aurelia Smart.
By reference to the contract it will be seen that two second vendor’s lien notes, executed by F. D. Turner and payable to J. O. Smart, were conveyed by Smart as part of the consideration for Osburn’s property, one for $2,-000, and the other for $1,668.2S, the two notes aggregating $3,668.28. These notes were secured by a second vendor’s lien on lot 1 in block 4 of the Brooklyn Heights addition, this being upon a different lot and in a different block from the lots conveyed by Smart to Osburn. The undisputed proof shows that there was a first vendor’s lien upon said lot 1 in block 4 to secure some $9,000, and that prior to the institution of this suit the owner of the $9,000 indebtedness in form and manner not questioned sold to a person other than Osburn said lot 1 in block 4 for the amount due upon the principal indebtedness, thus rendering the second vendor’s lien notes in question wholly valueless, and plaintiff further seeks to recover in this suit the value as agreed upon in the contract of the said second vendor’s lien notes, aggregating $3,-668.28, with a foreclosure of a vendor’s lien upon the lands conveyed by Osburn to Smart. The undisputed proof shows that the second vendor’s lien notes in question were not indorsed by Smart, the transfer being by a written instrument not attached to the notes, and therefore, under our Negotiable Instruments Act, Smart is not personally liable thereon. However, by section 49 of that act (Rev. St. 1925, art. 5934, §. 49), it is stated that, where the holder of an instrument payable to his order transfers it for value without indorsing it, the transfer vests in the transferee such title as the transferor had therein, and the transferee acquires, in addition, the right to have the indorsement of the transferor. Moreover, we see no reason why, where the facts or law require it, a purchaser may not be relieved of a personal liability and at the same time consent to a lien upon the property received by him to secure his personal note. It is to be noted also that the contract, after specifying the notes described, including the two second vendor’s lien notes, contains the following: “Seller to retain vendor’s lien and deed of trust to secure said notes. * ' * * ”
The language is certainly broad enough to include the right in Smart to a vendor’s lien upon the real estate he conveyed to Osburn to secure the payment of the notes secured by a lien thereon which Osburn assumed, and likewise broad enough to include the right to Osburn to the vendor’s lien upon the property he conveyed to Smart to secure the payment of the two second vendor’s lien notes received as part consideration for his conveyance. Osburn, as to his property, was undoubtedly a seller. These two vendor’s lien -notes were taken as part consideration. That they are worthless and invalid is not questioned by any finding, and, while the oral evidence was to the effect that there was no specific agreement during the negotiations that Osburn should have a lien to secure the payment of these notes, or for a personal judgment against Smart, yet, in view of section 49 of tl\e Negotiable Instruments Act (Rev. St. 1925, art. 5934, § 49) and of the language of the contract, we have concluded that in equity Osburn is entitled, in addition to the $900 item hereinbefore referred to, to the vendor’s lien upon the real estate conveyed by him to Aurelia Smart to secure the payment of these two second vendor’s lien notes taken by him as part of the consideration for the property. The section of the Negotiable Instruments Act referred to reads as follows: “Where the holder of an instrument payable to his order transfers it for value without indorsing it, the transfer vests in the transferee such title as the transferor had therein, and the transferee acquires, in addition, the right to have the indorsement of the transferor. But for the purpose of determining whether the transferee is a holder in due course, the negotiation takes effect as of the time when the indorsement is actually made.”
It is accordingly ordered that the judgment below be reversed and here rendered in favor of appellant, Osburn, in accord with our conclusions as noted, with direction for the issuance of all necessary process for its indorsement.
There is no complaint either in behalf of or against tile defendant F. D. Turner or the appellee Mrs. Aurelia Smart, and the judgment as to them is therefore left undisturbed, except the liens hereinabove mentioned established in favor of appellant, Osburn, are enforceable against both J. O. and Aurelia Smart. We wish also to add that our conclusions and decree which shall be entered in accordance therewith are not to be construed so as to prevent ' J. O. Smart or Aurelia Smart from seeking a subrogation to Osburn’s right to thé judgment rendered against F. D. Turner for any and all moneys that may be collected by Osburn under the decree -enforcing the equitable liens herein granted in his *1078favor. And it is further provided in this particular that, should it so happen that Os-burn at any time has been or shall be enabled to actually collect any sum or sums of money from or under.the said judgment against F. D. Turner, such sum or sums as shall be so collected, if any, or received under said judgment, shall operate as a credit pro tanto on the sums hereinabove specified as due Os-burn under this decree.
It is further ordered that all costs of this court and in the court below shall be taxed against appellee J. 0. Smart.
