— Plaintiff is indorsee of a negotiable promissory note and brought this action against defendant, an indorser who had waived demand, notice and protest. Plaintiff prevailed in the trial court and defendant has appealed.
The note was executed July 30, 1886, due three years after date, to defendant, by one Patton who, to secure the payment thereof, executed to defendant a mortgage or deed of trust on a certain lot in Kansas *217City. ' Patton sold the lot, in September, 1886, to one McKain who assumed the payment of the mortgage and •of the note in suit secured thereby. McKain after-wards, in December, 1889, .sold the property to one ■Schneider Meyer (subject to the aforesáid mortgage) who also assumed the payment of the note in suit. .Plaintiff had the land sold under the mortgage and the proceeds of the sale duly entered as a credit upon the .note. The suit is for the balance. After Schneider .Meyer assumed the payment of the note, plaintiff extended the time of payment to him upon his paying interest at the expiration of several periods of ninety days, thus compounding the interest at these intervals. The payment of interest in advance by the principal ■debtor is a sufficient consideration to support a contract ■extending the time of payment for a definite period. Stillwell v. Aaron, 69 Mo. 539; St. Joseph F. M. Co. v. Hauck, 71 Mo. 465. And in such case the surety is discharged. This proposition of law is well settled and the question now presented is whether they should ■apply to the facts of this case.
■ When defendant indorsed and delivered the note in suit to plaintiff (carrying with it the mortgage or deed of trust) plaintiff became, to all intents and purposes, the mortgagee with the right to sue Schneider Meyer directly at law upon his assumption of the debt .as grantee of McKain. Fitzgerald v. Baker, 70 Mo. 685. The ground upon which this right of the mo'rt.gagee creditor is based, is that the promise was made .for the benefit of the creditor. Defendant, as indorser ■of the note to plaintiff, became, in fact, though possessing additional rights, a surety to plaintiff for all those primarily liable on the note. She was thus a surety for Schneider Meyer, who became primarily liable by reason of his having assumed the payment of the note, with .all of the surety’s rights. “The surety is entitled to pay *218the debt when it becomes due, or he may call upon the creditor, by the aid of this court, to enforce his demand against the principal debtor. On paying the debt he is entitled to the creditor’s place by substitution; and if the creditor by agreement with the principal debtor without the surety’s consent, has disabled himself from suing when he would otherwise have been entitled to sue under the original contract, or has deprived the surety, on his paying the debt, from having immediate recourse to his principal, the contract is vailed to his prejudice and he is consequently discharged. ” King v. Baldwin, 2 Johns. Ch. 559; Smith v. Rice, 27 Mo. 505; Union Life Ins. Co. Hanford, v. 143 U. S. 187.
It was a right possessed by defendant to pay off this note at any time after it became due and thereby to become entitled to the mortgage with the right to immediately foreclose on the property described therein. She had the furtñer right to sue Schneider Meyer on his assumption of the debt. Now suppose she had chosen to exercise either of these rights, she would have found herself delayed,, hampered and embarrassed by the contract of extension which plaintiff had made-with Schneider Meyer. Defendant, by being subrogated to plaintiff’s rights in the mortgage, would stand in plaintiff’s shoes and, therefore, have to take it incumbered by the contract of extension. Calvo v. Davies, 73 N. Y. 211. Plaintiff has chosen to recognize Schneider Meyer as its debtor and has entered into-contractual relations with him as such debtor and has-interfered with defendant’s rights against him, be being liable to her, and has thereby discharged her. “It is a principle which is constantly acted upon and applied, that anything whatever done by a holder of a bill or note, which must necessarily have the effect of destroying, delaying, lessening, or in any way embarrassing the rights or remedies of other parties against parties-*219liable to them, discharges all the parties thus injuriously affected from any claim by the holder himself,, or by any one who must claim by or through him.” Grube v. Stille, 61 Mo. 475.
Plaintiff seeks to avoid the force of the contract of' extension of time, by the assertion that th6 extension of must be on a contract with the principal debtor and that Patton, and not Schneider Meyer, is the principal debtor in this case. But we have already seen that in this state it is settled that Schneider Meyer by his assumpsit became a principal .debtor to the holder of the note. Fitzgerald v. Baker, 70 Mo. 685; Heim v. Vogel, 69 Mo. 529; Fitzgerald v. Baker, 85 Mo. 13. And even in those states where a direct action at law is. not permitted, it is nevertheless held, that the mortgagee may in equity assert the mortgagor’s right against the grantee who assumes the debt. Otherwise there-would be circuity of action; the mortgagee creditor would be compelled to proceed against the mortgagor-debtor and the latter would then, in turn, be compelled, to go upon the grantee. Union Life Ins. Co. v. Hanford, 143 U. S. 187; Keller v. Ashford, 133 U. S. 622-625, and cases cited; Osborne v. Cabell, 77 Va. 467; Willard v. Worsham, 76 Va. 401; Crowell v. St. Barnebas, 12 C. E. Green, 650. So it is agreed everywhere-(whatever may be the mode of bringing about the result) that the creditor is entitled, as a right pertaining to his. situation, to take to himself the benefit of the contract assuming payment which the grantee makes with the mortgagor.
It is disputed that interest was paid -in advance. The facts are that the note drew “interest at ten per cent, per annum from maturity.” The contract of extension was based on the payment of interest at the expiration of each period of ninety days. This was a sufficient consideration to support the contract. The *220note drew simple interest at ten per cent, per annum. The effect of the several payments, upon which the extensions were made, was to compound the interest every ninety days. This was a benefit to the one party1 and an injury to the other, and possesses all the elements of a legal consideration. It is true that the compounding .of the interest more than once a year is prohibited by statute; and so is usury prohibited, yet the payment of usury is a sufficient consideration to support a promise of this sort. Weld v. How, 74 Mo. 551. So, whether compounding the highest legal rate of interest oftener than once a year should be denominated usury makes no difference, it •is, when paid, a payment of more than is due and is a sufficient consideration. The case of Moore v. Macon Sav. Bank (22 Mo. App. 684) is not applicable, since in that case the interest was only promised and had not in fact been paid. The promise to pay an illegal sum ■is a different proposition from its actual payment. See Stillwell v. Aaron, 69 Mo. 546.
It will be noticed that Schneider Meyer is the second grantee who assumed to pay the mortgage debt. This will not alter the result or affect the application of the principle herein asserted. For, “after the first grantee has covenanted to pay the mortgage debt, a like covenant in his deed to the second grantee makes the latter personally liable to pay it.” 1 Jones on Mortgages, sec. 747a. And this promise or covenant must necessarily, of cours'e, be held to be also, in'this state, for the benefit of the mortgagee. ,
The result is, that we must reverse the judgment.
All concur.
