delivered the opinion of the Court:
This was a bill in chancery, brought by Isaac Y. Brokaw and William Brokaw, to foreclose a mortgage upon certain real estate in Cook county, executed to them by Cornelius R. Field, Harriet M. Harvey and James M. Harvey, her husband. The legal title to the mortgaged premises stood in the name *660of Cornelius B. Field, it having been conveyed to him in fee, December 29, 1867, as trustee of Harriet M. Harvey, in trust to grant, bargain, sell or otherwise dispose of the same, in all respects, as the beneficiary of the trust should order and direct.
The mortgage sought to be foreclosed was executed December 27, 1872. It appears that for some time prior to that date, James M. Harvey had been engaged in business as a clothing merchant in the city of Chicago, and had been purchasing goods on credit, to a considerable extent, from the complainants, who were then doing business in the city of New York as copartners, under the firm name of Brokaw Brothers. While James M. Harvey seems to have been the real owner of the business, the goods, for some reason not fully explained, for a considerable time prior to the date of the mortgage, and for some time thereafter, were billed to Mrs. Harvey, and were charged to her account on Brokaw Brothers’ books. Whether she had anything more than a nominal interest in the business does not distinctly appear, although the fair inference from all the evidence would seem to be, that her husband was the real purchaser of the goods and the real debtor for their price. Mrs. Harvey appears, however, both then and afterwards to have been actively concerned in the management of the business.
In February, 1872, both Mr. and Mrs. Harvey were in the city of New York, and they there arranged for a credit with Brokaw Brothers, and for the purpose of furnishing security for the indebtedness which should be thereby incurred, they entered into an agreement in writing, under their hands and seals, dated February 29, 1872, the substantial portions of such agreement being as follows:
“Whereas, James M. Harvey and Harriet M. Harvey, his wife, of the city of Chicago, Ill., are desirous to furnish security for any and all goods that they have or may hereafter purchase of Isaac Y. Brokaw and William Brokaw, composing the *661firm of Brokaw Brothers, of the city and county of New York, do hereby make the following declaration, viz.:
“That the said Harriet M. Harvey is the owner in fee of a certain house and five acres of land in the town of Hyde Park, South Chicago, on the west side of Packston avenue, between 73d and 74th streets, which said premises are free and clear of all incumbrances of every nature and kind, except taxes for the present year, the said property being valued at the sum of fifteen thousand dollars:
“That, immediately on our return to Chicago, (within a few days), we do hereby promise and agree that a mortgage deed, or deed of trust, shall be made of said property, to the said Isaac Y. Brokaw and William Brokaw, conditioned for the payment of the sum of ten thousand dollars, or such part thereof as may at any time be owing to the said Isaac Y. Brokaw and William Brokaw, by us, or either of us.”
In pursuance of this agreement, James M. Harvey executed his bond to Brokaw Brothers, in the penal sum of $10,000, bearing date March 12, 1872, conditioned for the payment to the obligees of the amounts then due or that might therafter become due to them for goods sold and delivered to the obligor, at the time and according to the terms specified in such sales; and to secure such bond, Cornelius R. Field, the trustee, and Harriet M. Harvey and James M. Harvey, joined in the execution of a mortgage to Brokaw Brothers on the premises mentioned in the agreement.
These instruments were afterwards submitted by Brokaw Brothers to their counsel in New York, and he advised them that they did not fully carry out the intention of the parties as expressed in the agreement of February 29, 1872, the objection, according to his construction of them, being, that they did not constitute continuing securities, but were being constantly paid off and discharged by such payments as the debtors were from time to time making upon their indebtedness, and he recommended the cancellation of that mortgage and the taking *662of a new one securing a certain sum, made up of specific bills or purchases of a date prior to the date of the new mortgage, with an agreement that all payments afterwards made should be credited on other accounts or purchases. He also wrote to Mr. and Mrs. Harvey’s legal adviser in Chicago, stating fully his objections to the existing bond and mortgage, and suggesting the execution of a new mortgage in the form just stated.
As a result of this advice and correspondence, the mortgage now sought to be foreclosed was executed. That mortgage, as has already been stated, was executed by the same parties, viz., Field, the trustee, and by Mrs. and Mr. Harvey. No bond seems to have been executed with it, but the mortgage itself recited that James M. Harvey was indebted to Brokaw Brothers in the sum of $10,032.65, for merchandise sold and delivered by them to him, stating specifically the dates and amounts of fifteen different sales, aggregating that amount, the date of the first item being September 24, 1872, and of the last October 31, 1872. It was further recited that James M. Harvey had agreed to pay the indebtedness thus scheduled on or before three years from the date of the mortgage, with semi-annual interest at the rate of seven per cent per annum, payable on the 27th day of June and December of each year, until the principal sum should be fully paid, interest to be computed only from the expiration of four months after the dates of the respective sales. The mortgage then provided that the mortgagors, “for the better securing the payment of the money aforesaid, with interest thereon, according to the tenor and effect of the agreement aforesaid, and also in consideration of the sum of one dollar to them in hand paid by the parties of the second part, at the delivery of these presents, the receipt whereof is hereby acknowledged, have granted, bargained, sold,” etc., describing the same premises conveyed by the former mortgage.
*663Concurrently with the execution of the mortgage, Cornelius E. Field, trustee for Harriet M. Harvey, and Harriet M. Harvey and James M. Harvey, joined in the execution of an instrument of the following tenor:
“We hereby consent that hereafter all payments made by James M. Harvey to Brokaw Bros., of New York, may, whenever any indebtedness is due and payable from said James M„ Harvey to said Brokaw Bros., other than that named in the mortgage this day executed by us to said Brokaw Bros., be applied to such other indebtedness. ”
The account with Brokaw Brothers seems to have been continued in the name of Mrs. Harvey down to May 21,1873, at which date it was balanced and closed, and the amount then appearing due was charged on their books to James M. Harvey. He thereafter continued a running account with them down to August 30, 1875, at which date a written agreement was,entered into between him and them, in which it was recited that the indebtedness, on settlement, amounted to $14,183.39, and that Harvey had given his twelve promissory notes therefor, payable respectively at the end of each month for twelve months from their date, and it was agreed that, upon the payment of each note, Brokaw Brothers would supply goods to Harvey to the amount of seventy-five per cent of the note paid, Harvey to settle on the first day of each month for the goods which he might thereafter receive, by giving his note due in four months. Isaac Y. Brokaw testifies that no part of the indebtedness secured by the mortgage was included in the settlement, and we find no evidence disputing his testimony in that respect.
On the 30th day of December, 1877, James M. Harvey died testate, and by his last will and testament,—after making certain specific bequests,—he gave one-half of the residue of his property to Harriet M. Harvey, his widow, and a one-fourth interest in his business to each of his two sons, James M. Harvey Jr. and Frank W. Harvey. His will also appointed *664his widow and his two sons his executors, and they acted as such, the estate being settled and the executors discharged January 26, 1885. James M. Harvey, during his lifetime, paid various sums of money to be applied upon his indebtedness to Brokaw Brothers not included in the mortgage, but leaving, as it seems, $6588.11 of the unsecured indebtedness unpaid at the time of his death. No payments on the indebtedness secured by the mortgage were made by him except, the interest. Neither the indebtedness secured by the mortgage, nor that which was unsecured, was presented in the Probate Court as a claim against the estate.
After the death of James M. Harvey, his widow and two sons took control of the business and carried it on under the firm name of Harvey Brothers. That continued until some time in 1881, when Mrs. Harvey withdrew therefrom. Harvey Brothers continued their dealings with Brokaw Brothers, and in the course of such dealings, they paid the unsecured indebtedness in full, such payments being made before the estate was settled, and within-two years after the death of Harvey. They also paid the interest on the mortgage to June 27, 1883, the rate of the interest, however, having been reduced by agreement of the parties, from seven to six per cent, shortly before the death of James M. Harvey, the reduction commencing June 27, 1876.
The pleadings in the case are exceedingly, and as we think, unnecessarily complicated, and. no useful purpose would be subserved by any attempt on our part to disentangle them or show the precise manner in which the various propositions of fact upon which counsel now rely are presented. At the hearing, which was had on pleadings and proofs, the court found the material allegations of the bill to be true, and found that there was due the complainants on the mortgage the sum of $14,492.85, that being the principal sum secured by the mortgage and interest thereon from June 27,1883, to May 9, 1890, the date of the decree, and certain moneys paid by the *665complainants for taxes on the mortgaged premises and interest thereon. The court thereupon rendered the usual decree of foreclosure, and for the sale of the mortgaged premises to make the amount thus found due and costs. That decree has been affirmed by the Appellate Court on appeal, and this appeal is from the judgment of affirmance.
The first point urged on behalf of the appellants is, that there is a variance between the allegations of the bill as to whose indebtedness was secured by the mortgage and the proof upon that question. The original bill alleged that, on the day of the date of the mortgage, James M. Harvey was indebted to Brokaw Brothers in the sum of $10,032.65, setting forth specifically the several items of indebtedness scheduled in the mortgage, and that being so indebted, he agreed to pay such indebtedness to Brokaw Brothers on or before three years from that date, with interest as specified in the mortgage, and that to secure such indebtedness, the defendants executed the mortgage, the bill setting out a copy of the same to be taken as a part of the bill. The complainants afterward, hy leave of the court, amended their bill, by striking out the name of James M. Harvey where it first occurs therein, and inserting in lieu thereof that of Harriet M. Harvey, and alleging that, while the mortgage referred to the indebtedness as that of James M. Harvey, it was in fact the indebtedness of Harriet M. Harvey, for goods sold and delivered to her, and for which she was charged on the complainants’ books; that credit was extended to her on the faith of her ownership of the mortgaged premises, and her promise to give a mortgage.
Subsequently the bill was again amended, so as to allege that, on February 29, 1872, Mr. and Mrs. Harvey were concerned in and carrying on the business of a clothing merchant in Chicago, in the name of one or the other, or in the interest of one or the other, and that both were actually concerned in the establishment, and in having the same carried on. The *666bill sets up the contract of February 29, 1872, the substance of which has already been stated, and alleges that the complainants, relying upon the representations contained in that instrument, extended credit to them to the amount of $10,-032.65, for merchandise sold and delivered by the complainants to them, to be added to the stock in the store in Chicago conducted by them or in which they were interested, and that credit was given to Harriet M. Harvey, and the goods were billed and sent to her address in Chicago, and that to carry out their undertaking, the mortgage was executed reciting that James M. Harvey was indebted for the goods sold and delivered to him, and that he had agreed to pay for them on or before three years from that date with interest; that while the mortgage referred to the indebtedness as that of James M. Harvey, it was in fact the indebtedness of Harriet M. Harvey, for goods sold and delivered to her, and for which she consented to be and was charged; that the mortgage was drawn at the instance of Mr. and Mrs. Harvey and by their direction, or that of one of them, and was recorded in the absence of the complainants, without the intention of changing the personal liability of Harriet M. Harvey for the indebtedness, and it should be held as security for the indebtedness as if Harriet M. Harvey was principal, as she in fact was and is.
Now if it be conceded that the evidence proves, as the court found, that the indebtedness in question, at the time it was incurred, was in fact that of James M. Harvey, we are unable to see that' there is any such variance between the allegations of the bill and the proofs as can constitute any valid objection to the decree as rendered. So far as that question is concerned it seems to us to be quite immaterial whether, prior to the execution of the mortgage, the indebtedness which that instrument was executed to secure was that of James M. Harvey or his wife. By the mortgage, to which they both were parties, and by the recitals of which they were both bound, it was declared to be the indebtedness of James M. Harvey, and *667it was recited that he had. agreed to .pay it, and it thereby became, for all the purposes of giving validity to the mortgage, his debt. If he was in fact the debtor, as the court finds he was, all that can be said is, that the allegations of the bill seeking to charge Mrs. Harvey as the original and therefore the principal debtor are disproved, and that the complainants are entitled to take nothing by those allegations. But the right of the complainants to a foreclosure of the mortgage and sale of the mortgaged premises does not rest at all upon those allegations. Whether the indebtedness for which the mortgage was given was originally that of Mr. Harvey or of his wife, they have, by the mortgage, agreed to treat it as Mr. Harvey’s indebtedness and to secure its payment as such, and the validity of the mortgage in no way depends upon who was in fact the original debtor.
We may conjecture that the complainants’ attempt to show that Mrs. Harvey was the original and therefore the principal debtor, was made for one or both of the following purposes, viz: (1) to entitle themselves to a deficiency decree against her in case the mortgaged premises should not sell for a sufficient sum to satisfy the amount secured by the mortgage and costs, or, (2) to show that she could not have sustained the relation of surety to her husband, so as to relieve the case of those legal consequences which the defendants are seeking to reach by setting up and insisting upon that relation. But the failure to prove her the principal debtor constituted no such variance between the allegata and the probata as made it improper for the court to award a decree of foreclosure and sale.
The next point made is, that the evidence tends to show that a bond.was executed with the mortgage sought to be foreclosed, and that before foreclosure should have been had, the bond should have been produced, or its absence accounted for. No bond is referred to in the mortgage, and from that fact alone a strong inference arises that none was executed. The only evidence tending to show the existence of a bond is *668found in a mere reference in a letter from the complainants to Harvey, dated September 24, 1873, to “the bond we hold,” and in an entry on the complainants’ books of a credit to-Harvey of $10,032.65, “by bond and mortgage on property in Hyde Park,” etc. Isaac Y. Brokaw testifies that there was no bond with that mortgage, so far as he knows, and that the credit on the books, so far as it referred to a bond, was a clerical error. In view of all the evidence, we think the court was justified in holding that the execution of a bond was not proved, and in not requiring its production.
It is next contended that the complainants’ right to a decree of foreclosure is barred by the Statute of Limitations. The mortgage, by its terms, became due December 27, 1875, and the original bill in this case was filed July 22, 1884, which was less than ten years after the maturity of the mortgage. Section 11 of the Statute of Limitations provides that no action for the foreclosure of a mortgage shall be commenced, unless within ten years after the right of action accrues. It would seem to be very plain that the present action was commenced within the period of limitation thus fixed.
But the position seems to be taken that, as the indebtedness secured by the mortgage was an open account, a different period of limitation should be applied. Without attempting to decide whether a mortgage which merely secures an open account, without furnishing in itself any written evidence of the indebtedness, should be subject to the limitation provided in section 15 of the act, it is sufficient to say that this is not that case. While no promissory note or bond was executed as evidence of the debt, the mortgage itself recites, and by such recital admits, the indebtedness, its character and amount, and also recites, thereby admitting an express promise on the part of Mr. Harvey to pay it. These recitals and admissions constitute of themselves written evidence of the indebtedness, bringing an action for its recovery within the limitation provided in section 16, viz., ten years.
*669But it is claimed that Harvey failed to pay certain installments of interest which became due more than ten years before the commencement of the suit, and it is insisted that the right of action for the foreclosure of the mortgage then accrued, and that the statute therefore then commenced to run, and that although those installments of interest were afterwards paid by Harvey in his lifetime, such payment did not arrest the running of the statute, and that ten years having elapsed after the first default and before the commencement of the suit, the right to foreclose must be deemed to be barred. It is true the mortgage contains a power of sale in case of default in the payment of the money secured or any part thereof, or of the interest or any part thereof, according to the tenor and effect of the agreement recited in the mortgage, but there is no provision in relation to a foreclosure by suit in case of such default, or declaring or giving the mortgagees power to declare the principal due in case of default in the payment of interest. Under these circumstances it seems clear, that the statute did not commence to run as against the principal indebtedness until it became due by the terms of the mortgage, and as the interest once in default has been paid, no question can arise as to whether that is barred by the statute.
The next point made is, that Mrs. Harvey executed the mortgage as a mere surety for her husband, and that under the provisions of section 3, of chapter 132, of the Revised Statutes, she is relieved from the payment of the mortgage to the extent that the mortgage indebtedness might have been collected from the estate of her husband, if it had been presented in proper time in the Probate Court. That section provides that, whenever the principal maker of any note, bond, bill or other instrument in writing shall die, if the creditor shall not within two years after the granting of letters testamentary or of administration present the same to the proper court for allowance, the sureties thereon shall be released from *670the payment thereof to the extent the same might have been collected of such estate, if presented in proper time.
No statute of this character was in existence at the time the mortgage in question was executed, the statute here referred to having gone into force July 1, 1874. The question then is whether, if it be admitted that Mrs. Harvey executed the mortgage as a mere surety, the statute is to be given a retroactive effect, so as to apply to this mortgage. This question, as applied to a statute quite analogous to the one relied upon here was fully considered by us in Fisher v. Green, 142 Ill. 80, and we held that the statute there under consideration did not have a retrospective operation. What we said in that case will, in the main, apply here, and need not be repeated. It may also be noticed that the act of 1869, which provided that a surety upon a joint note should be released by a failure of the holder to present the same to the proper court for allowance against the estate of the principal, upon his death, has been considered by this court in its application to notes executed after its passage. House v. Trustees of Schools, 83 Ill. 368; Curry v. Mack, 90 id. 606; Huddleston v. Francis, 124 id. 195. In these cases it was held that the statute there in question was not a mere statute of limitation, but that it was to be considered as entering into and forming a part of the contract itself. While statutes in force at the time a contract is made are usually to be regarded as entering into and forming a part of the contract, upon the theory that parties must be deemed to contract with reference to existing laws, so as to adopt those laws- as parts of their agreements, the same force can never be given to statutes subsequently enacted. Parties are not presumed to contract with reference to the provisions of future statutes, and such statutes can not be said to enter into or form a part of their agreements. It is plain then that the basis upon which the act of 1869 was enforced in the cases above cited is wholly wanting where an attempt is made to apply the act of 1874 to a mortgage executed in 1872.
*671The further point is made—and it is the one upon which principal reliance seems to be placed—that Mrs. Harvey having executed the mortgage merely as surety, the complainants have so dealt with her principal as to release her and her property from liability.
The contention is, first, that she was released by the modification of the contract by which the rate of interest was reduced from seven to six per cent. The evidence however warrants the conclusion that this reduction in the rate of interest was made not only with her knowledge, but at her express solicitation, and that being the ease, her liability as surety could not have been affected by it.
It is next contended that she was released by certain extensions of the time of payment of the money secured by the mortgage. We have examined the evidence with care, and fail to find any satisfactory evidence that any such contract of extension was ever made. It is shown that after the mortgage became due in 1875, it was allowed to run along from year to year, the interest being paid with more or less of regularity until June 27, 1883, but it is not proved, so far as we are able to find, that any contract, upon a valuable consideration, for an extension of the time of payment for a definite period was ever entered into. Merely allowing the mortgage to run from year to year and receiving payment of the interest is not sufficient to discharge a surety. To have that effect, there must be a valid and binding agreement for an extension, for a definite period, entered into, upon a valuable consideration. No such agreement seems to be proved.
Furthermore, since the death of her husband in 1877 she, as one of his executors, and especially as one of his residuary legatees, has been one of his legal representatives, and so far as she has occupied that position, she has taken his place as principal in the mortgage. Upon his death, she, with her two sons, entered into, took charge of and carried on the very business out of which the indebtedness secured by the mort*672gage grew. Whatever was afterwards done in relation to the mortgage, was done by the executors, of whom she was one, or by the firm of Harvey Brothers, of which she was a partner. It is difficult therefore to see how any dealings with the mortgagees could have taken place after her husband’s death without her knowledge or her personal participation. What was done was done either by herself or by others for whose conduct in the matter she was personally responsible. And what was done under such circumstances can hardly be said to have the effect of discharging her from her obligations as surety.
Field, the trustee, has filed an answer and cross-bill in his own behalf, seeking to claim for himself the position and immunities of a surety, and praying that the legal title vested in him be discharged from the lien of the mortgage. It is clear that, under the declaration of trust in the deed conveying the premises in question to him, he has no title or estate which can enable him to set up or claim for himself, independently of his beneficiary, any equities in the mortgaged premises, and that whatever is binding on her is in like manner binding upon him. He holds the mere naked legal title, to be disposed of by him as his beneficiary sees fit to direct, and beyond that he has no rights in or control over the premises. The defense set up by his beneficiary to the mortgage having failed, his defense must for the same reason fail also.
After carefully considering all the objections urged to the decree, we are of the opinion that none of them are well taken, and the only result we are able to reach is, that the judgment of the Appellate Court affirming the decree must be affirmed.
