— The contract sued on is a rather unique one, and one which presents difficulties of interpretation and of classification. It is as follows:
1 ‘Agreement.
“This agreement made and entered into by and between Louise Schnuettgen of Earling, Iowa, party of the first part, and R. H. Mathewson, president of the Farmers National Bank, Wakefield, Nebraska, party of second part, as follows:
“The said party of first part being owner of mortgage covering north fractional one half of Section .19, Township 89, Range 46, west of the 5th P. M., said mortgage bеing recorded February 2, 1928, in Book 272 of Mortgages, on page 128, Records of Woodbury County, Iowa, and whereas the said, party of second part has, or soon will acquire title to above described land, covered by said mortgage, and agrees to pay all taxes accrued, and becoming due, and pay all interest on first mortgage to Peters Trust Company and second mortgage to said first party from February 1, 1924, to maturity of said loans, and it is agreed that should said second party desire an extension of three years from maturity of said second mortgage from February 1, 1926, at same rate, namely six and two thirds per cent, said first party agrees to grant such extension, provided second party shall pay said first party in cash February 1, 1926, the sum of six thousand dollars, and extend balance of mortgage as specified above, provided said second party or his assigns shall have kept all interest and taxes paid promptly.
“This agreement binding on both above parties and their assigns, and heirs of first party.
‘ ‘ Signed at Earling, Iowa, this 1st day of October, 1924.
‘ ‘ [Signed] Louise Schnuettgen, “R. H. Mathewson.”
The petition set forth this contract, аnd alleged that the defendant had failed and refused to pay the_ taxes, and failed and refused to pay the interest on the first mortgage* and had failed and refused to pay the interest on the second mortgage, to the total amount of (as amended) about $8,000. A perusal of the contract and of the allegations of the petition concerning the same conveys no intelligence to the reader as to what *296 rights have accrued thereunder to the plaintiff, .or as to what issues are tendered in her pleading. The contract becomes intelligible only as it has been supplemented by oral evidence and by certain other writings. In that respect, the contract between the parties may fairly be deemed to be partly in writing and partly oral. The land described in the contract was a half-section farm, first owned and mortgaged by one Grover. He had executed a first mortgage for $28,000 to the Peters Trust Company, and a second mortgage for $36,000 to the plaintiff. One Kellogg, a relative of Grover’s, had some interеst in the ownership, not of record, and he was active in bringing about the negotiations which resulted in the contract. The plaintiff is an elderly lady, living at Earling, and did not personally carry on the negotiations. She was represented in these by Kohles, a son-in-law. The defendant is a banker at Wakefield, Nebraska. He appears to have been an unsecured creditor either of Kellogg’s or Grover’s, or both. Kellogg proposed to secure him by conveying the title to him as security, thereby making him a junior incumbrancer of thе land. As between Kellogg and the defendant, the purpose appears to have been to obtain for the mortgagor sufficient additional credit to pay the accruing interest on the two mortgages and to pay the taxes, in order to avoid foreclosure of the mortgages. The taxes for one year were already past due, and' .perhaps one semiannual installment of interest on each mortgage. It was pursuant to this plan .that the contract sued on was executed. The defendant еntered into possession of the land, after receiving the deed, and farmed it for the year 1925. He applied all the proceeds of the farm operations to the payment of the obligations referred to in the contract. These proceeds, however, were insufficient to meet the call of the contract.
There is some dispute between the parties — not a very material one — as to the, date upon which the1 contract was signed. It purports to have been signed on October 1st, and the-contention for the plaintiff is that it was executed on that day or the day following; whereas it is the contention of the defendant that it was signed by him on the last day of November or the first day of December. The contract was drawn at Earling, and was signed there on the first day of October by the plaintiff. It was taken by her son-in-law, Kohles, to Wakefield, *297 and presented to the defendant on the following day. Kohles testified that it was immediately signed by the defendant, and the whole transaction closed. It is the contention of the defendant, as witness, that it was not signed on that day, although it was discussed, and that the transaction was left open, to await the conveyance to the defendant. It is undisputed that Kohles returned about the last day of November, and that further negotiations were resumed, and that an additional paper was signed on that day, which will be referred to later. That was the day upon which the defendant received conveyance of the title. A careful reading of the evidence satisfies us that the transaction was not deemеd closed between the parties until the last day of November or the first day of December. The language of the contract shows that it was predicated upon the assumption that the defendant was to receive title to the land. It was as such owner, and not otherwise, that the defendant purported to enter into the undertaking. This conclusion is fortified by the fact that, on the first day of December, Kohles entered into an undertaking which operated materially as representation and inducement to the signing of the contract by the defendant, as will hereinafter appear.
On October .20, 1925, the plaintiff began foreclosure suit of her mortgage by personal service of notice on that date, both upon Grover and wife and upon this defendant, Mathewson. Her petition was filed on October 23, 1925. In her petition she prayed for judgment for the principal only, in the sum of $36,000. She prayed no recovery for interest against either defendant. Decree was entered for her as prayed, on January 5, 1926, for $36,000, and no more.
On Octоber 20, 1925, she likewise began the instant action against the defendant alone, predicating the same upon the written contract above set forth. Both actions were brought in "Woodbury County district court, and both were pending therein up to the time of decree in the first action. Pursuant to her foreclosure decree, the plaintiff sold the mortgaged land under special execution on March 5, 1926, and became the execution purchaser at a bid of $30,000, leaving a deficiency judgment of $6,000 against Grover. After execution sale in the foreclosure case,, the defendant filed his answer in the case at bar, wherein, among other defenses, he pleaded the bar of the foreclosure de *298 cree as a prior adjudication. He also predicated defense upon the provisions of Section 12375, Code of 1924, which provides as follows:
“12375. Separate suits on note and mortgage. If separate actions are brought in the same county on the bond or note, and on the mortgage given to secure it, the plаintiff must elect which to prosecute. The other will be discontinued at his cost.”
I. We proceed first to consider the question whether the foreclosure decree operated as a bar to the present action, on the theory that it was a prior adjudication, and that the maintenance of two actions was a mere attempt to split one cause of action. The determination of this question depends upon the nature and the interpretation of the writing which is set up as a cause of аction herein. The plaintiff sues upon the writing as upon a promise to pay. It is conceivable that the writing might be construed as a mere covenant, for the breach of which an action for damages would lie. But inasmuch as the plaintiff has sued and recovered upon it as an absolute promise to pay, we shall confine our discussion to such interpretation thereof. The interpretation of plaintiff is that the writing constitutes a distinct and independent cause of action, and that it stands upon its own base, as an absolute prоmise to pay. As already indicated, the contract itself is quite incomplete in its terms, and requires the aid of extrinsic evidence for the disclosure of its scope and purpose. It must be interpreted, therefore, in the light of the circumstances surrounding its execution. Was it independent, as a new or additional cause of action ? - Or was it a security for a cause of action already existing? If the plaintiff’s existing mortgage and the note which it secured, and this contract, constituted but one debt, then, under the authorities, a decree of foreclosure of the mortgage operated as a full remedy, and operated to bar another action to recover for any part of the same debt. And this is so even though the decree awarded to the plaintiff less than she was entitled to.
To speak negatively, the contract before us was not an assumption of a mortgage by the vendee as a part of the' purchase price, whereby the vendee became primarily liable for the debt; nor was it a novation, whеreby the original debtor contracted for release in consideration of the promise of the new debtor to pay *299 the debt; The new contract created no new asset in the hands of the plaintiff. It did operate-as a security to an asset which she already had. In its relation to plaintiff’s note and mortgage, the contract has a double aspect. Plaintiff’s note was secured by the mortgage. As to the note, therefore, this contract operated as additional security. As to the mortgage, it оperated as a promise to pay in part the same debt as was already secured by the mortgage. The plaintiff did not release her- mortgage to any extent. Nor did she surrender- any right under her- note or mortgage which she had against her original debtor. The contract created a new debtor, but not a new debt. The right of the plaintiff to sue upon this contract was dependent upon her right to sue upon her note and mortgage. She could recover nothing upon this contract in excess of the interest due her upon her note from her original debtor. Only as a holder of the unsatisfied note and mortgage could she recover at all upon this contract. If her original debtor were to discharge the' debt, it would ipso facto terminate liability under this contract. She could not maintain an action upon it as a promise to pay, without showing her present ownership of the unsatisfied note and mortgáge. Manifestly, this contract was not transferable, as a separate and distinct asset. To be suable at all, it must be by the holder of the note and mortgage. This of itself illustrates that it was not a self-supporting and separate cause of action, but an incident only to a previously existing cause of action. In her foreclosure suit, the plaintiff brought into court, by personal service, both the original debtor and this defendant. She claimed no interest as against either of them, though she was entitled to it as against both of them. She’ took decree accordingly for the principal sum alone; Such decree became a complete bar to further recоvery- against the original debtor. Why should it be deemed less so as against -the additional debtor? The legal effect of the decree was to say that no interest was due her from her debtor. She necessarily contradicts the íegal effect of her decree when she now claims to recover the interest from the additional debtor. The apparent theory of the plaintiff herein was that she would treat this defendant’s contract as the equivalent of payment of the interest. If that theory were enforcеd upon her, she would not have been permitted to maintain her foreclosure suit at all. Her note and mortgage were -not due *300 when she began her. suit, except as she was privileged to accelerate the due date because o£ default in the payment of interest. She alleged in her foreclosure petition that she had elected to declare her note due because of default in the payment of interest. Whose default was it upon which she declared? Not that of the original debtor, because she exonerated him. If it was the default of this defendant, then, upon her theory, she could declare this contract due. Such-default of this defendant would not render the mortgage due unless his contract; wra-s an adjunct of .the mortgage. The plaintiff .has, therefore, by her own procedure demonstrated the singleness of her debt and the unity of note, mortgage, and contract. We think it must be, held, therefore, that only one debt was due to the plaintiff, and that it was secured both by the mortgage and by the contract. .
We have held that a mortgagee may maintain a personal action on his note against the debtor, and may, after judgment therein, foreclose his mortgage.. But we have never, held that, a mortgagee who has foreclosed his mortgage by good personal service may afterwards maintain a separate action upon his promissory note. Indeed, we have held affirmatively to the contrary.
Kenyon v. Wilson,
The fact that the plaintiff in her foreclosure suit prayed for less than she was entitled to, and took decree accordingly, does not save to her the right to recover by a second action. When she prayed and obtained an adjudication which measured the full liability of the mortgagor as being the amount of the principal debt, without interest, she fixed his status, irrevocably. No less did she fix the status of the other defendant, — and for like reason. ■ ■
In
Kenyon v. Wilson,
“An adjudication is final and conclusive of all matters in a case which the parties could have presented to the court for adjudication in the case. The law hates a multiplicity of suits, and will not permit a plaintiff to split up his demands, presenting one at a time, in separate successive actions. He must litigate all matters growing out of Ms causes of action u-pon wMch a remedy may be sought in one action. Thus he, cannot seek a foreclosure of a mortgage in one action, and in a subsequent action ask for a personal judgment against the defendant. He could have recovered both remedies in the first action, and must be content with whát he first recovers. Hempstead v. City of Des Moines,63 Iowa 36 ; Oliver v. Montgomery,39 Iowa 601 ; Sweeny v. Daugherty,23 Iowa 291 ; Campbell v. Ayers, 1 Iowa [Cole] 257.”
In
Merrifield v. Clark,
“ ‘It is a general rulé that á judgment is conclusive of whatever might have been litigated in the actiоn in which it was rendered, and that a party must bring forward in one suit all the claiiñs dr defensés which he has, which aire included -in or applicable to the ■ cause of action in suit. Hence, in general, additional facts bearing on the original cause of action, and which might have been .presented in the first action, as distinguished from facts which have-occurred since that action, will not be sufficient to sustain a new suit.’ ” - -
*302 The rule applicable is discussed in 1 Ruling Case Law 358, Section 35, as follows:
“In a mortgage foreclosure suit, all the relief that the plaintiff is entitled to must be sought in that suit, and if he fails to seek it, he cannot afterwards mamtain am, action for any relief which he could have obtained in the foreclosure suit, had he asked for It. For example, if in a mortgage foreclosure suit the plaintiff is entitled to reimbursement for certain taxes paid by him on the property sought to be foreclosed, and he fails to seek reimbursement, his right to reimbursement is gone'; for to permit him to maintain another suit for reimbursement. would be to permit him to split thé action.”
An extensive discussion of the same subject will be found in
Smith Lbr. Co. v. Sisters of Charity,
One further fact, which confirms this conclusion, should have been stated eаrlier in this discussion. In her foreclosure petition in the first action, the plaintiff pleaded the contract now sued on, by the following allegations:
“That, on the first day of October, 1924, the defendant, R. H. Mathewson, entered into a written agreement with the plaintiff, under and by virtue of the terms of which the defendant, R. H. Mathewson, agreed to pay all taxes accrued and becoming due on said above described premises; and further agreed to pay all interest on the first mortgage then' upon said premises and the second mortgage sought to be foreclosed herein, from February 1st, 1924, to the maturity dates of said mortgages, and the plaintiff, makes no claim herein for the taxes and interest agreed to be paid by the'defendant, R. TL Mathewson.”
It is the contention, of plaintiff that by the foreg-oing allegations she reserved her cause of action. Clearly, there was no reservation in terms. On the contrary, the express terms purported to be a relinquishment of any claim against Mathewson upon such contract.
*303 Nor, indeed, could the plaintiff split her cause of action by mere allegation, or purported reservation of a part thereof. Nor did the decree purport to make any reservation to the plaintiff, as against either defendant.
II. It appears from the record that, at the time of the consummation of fhe contract relied on by the plaintiff, another contract was entered into between this defendant, Mathewson, and Kohles, the son-in-law of plaintiff, who was representing her in the negotiations with Mathewson. Such contraсt was as follows.:
“This ágreement made by and between George J. Kohles and Carrie M. Kohles, his wife, and R. H. Mathewson, in consideration of two agreements, one dated October 1, 1924, and the other dated October 2, 1924, between Louise Schnuettgen and R. H. Mathewson, on connection with the second mortgage held by Louise Schnuettgen on'the north half (N%) of Section nineteen (19), Township eighty-nine (89), Range forty-six (46), west, 6th P. M. Woodbury County, Iowa, it is hereby understood that the first parties are owners of ten thousand ($10,000) dol lars of the above mentioned thirty-six thousаnd ($36,000) dollars mortgage, same being in the name of Louise Schnuettgen.
“First parties hereby agree to pay interest on ten thousand ($10,000) dollars of the said mortgage that will' be due February 1st, 1925, and also February 1st, 1926. If the three-year extension on said mortgage is made as per the former agreements above mentioned, first parties will continue to pay interest on $10,000 of same until due.
“First parties further agree to pay five thousand ($5,000) dollars of the six thousand ($6,000) dollars payment that is agreed to be paid on February 1st, 1926.
“In consideration of the above, second parties agree hereby to fulfill the former contracts made October 1, and October 2, 1924.
“Dated at Wakefield, Nebraska, this first day of December, 1924.
“Witness:
“Margaret Kellog.
“George J. Kohles,
“Carrie M. Kohles,
“R. H. Mathewson.”
*304 It was represented therein by Kohles that he was the owner of $10,000 of the $36,000 mortgage. It will be noted also that the first contract' considered in the foregoing division did not specify the sum upon which interest was to be paid. The contract with Kohles purports to relinquish, as against Mathewson, any claim for interest on any excess over $26,000. This contract necessarily operated ás a material part of the consideration for the other. From the testimony of Kohles at the trial it appears that the interest of the plaintiff to the extent of $26,000 was prior and superior, as a lien, over the remaining $10,000. From the extrinsic evidence it appears that the mortgage held in her .name was for $36,000. From like evidence it appears also that the extent of her interest in such mortgage was only $26,000. It further appeax's that the mortgaged property was sold at execution sale, and that plaintiff purchased the same at execution sale on a bid of $30,000. She thereby extinguished all the mortgage debt, so far as her interest was concerned, Her bid would pay the full amount of her principal and interest. This being so, she had no interest in the prior incumbrances upon the land, nor in the unpaid deficiency judgment. The deficiency judgment would belong to the son-in-law.
The plaintiff’s response to the matters here stated is that Kohles hp,d no authority from plaintiff to enter into the contract in question, аnd that there was no evidence in support of the claim that he owned $10,000 ,of such mortgage, The only witnesses used on the trial by the plaintiff wexve Kohles and his wife. As a witness, Kohles admitted the execution of the contract here considered. True, he testified that it was signed pursuant to negotiations with Kellogg, ,rather than with Mathewson personally, and that Mathewson’s signature was .already on the contract when he signed it. As to the ownership of an interest in the mortgage, he-testified: . . .
“I had a second mortgage on this land before the plaintiff’s second mortgage was made. Thе present mortgage is all in her name. She agrees to give us $10,000 if she gets all of it. That is the understanding between us. Yes, if she gets her money back, which will be all but $10,000, and the $10,000 is collected, it is ours: ' Yes, I had that interest in the mox’tgage in 1924 and 1925.”
Also: “We were willing to pay the intex-est on that amount. *305 We'said we-would'knock off the interest, pay the interest .on $10,000, and pay this $5,000 as it is in the contract.”
The plaintiff submitted her case with full knowledge of the contents of the contract thus signed by her son-in-law, and the representation of ownership made therein. Though he was her witness at the trial,.-she had a right to contradict his tеstimony if it was not true. She neither repudiated the representation,of ownership made by him in the contract itself nor did she dispute his testimony. We think this evidence was sufficient to show that the full extent of plaintiff’s interest in the mortgage was $26,000, as principal. The contract of Kohles, therefore, operated upon the remaining $10,000.
III. The decree appealed from herein awarded recovery to the plaintiff, not only for interest upon the $36,000 mortgage', but also for the full amount of delinquent taxes, and for the full áthount of inthrеst accrued on the first tho~tgage from February 1, 1924, to the date of the execution sale, March 5, 1926. So far as is disclosed by the record, the plaintiff had paid. none of these items. . They simply rested as prior liens upon the land. Some of these interest coupons were held by Kohles, as assignee thereof. Under the assignment to him, the lien of these coupons was subordinated to the lien of the first mortgagee. They still formed a part of the incumbrance upon the land. In placing a bid of.$30,000 at the execution sale, the.plaintiff took the land subject to the then existing prior incumbrances. At the time of the decree in the case at bar, October, 1926, the land was still subject to redemption. Any redemptioner would have been required to pay the plaintiff the full amount of her bid, with interest, and to take the land charged with all the prior incumbrances. In such event, the plaintiff could have no interest in the' question whether the incumbrances were paid or not. As an execution-purchaser, she could stand in no better position than that of any other execution-purchaser, or than that of a redemptioner. She was not'suing for damages. She brought her suit upon the contract as upon a promise'to pay. -But there was no promise to pay the taxes 'to her, nor any promise to pay to her interest on the first mortgage. ' it is manifest, • therefore, that these items should not have been 'included in her 'recovery.
•Other quéstions' are presented and- arguhd; but, in view of *306 our foregoing conclusions, they lose their importance. For the various reasons herein indicated, the plaintiff’s petition should have been dismissed.
It is so ordered, and the decree below is, accordingly,— Reversed.
