Boykin and wife purchased from L. B. Russell, Jr., 777 acres of land in Comanche county for a recited consideration of $23,-310, of which a part was cash and the balance was the assumption by Boykin of certain vendor’s lien notes executed by Russell to the First State Bank of Comanche, defendant in error, hereinafter referred to as the State Bank. Boykin and wife immediately moved upon the land, using same as their homestead, which use had continued to the date of the trial of this case. Two years after they acquired this land and. moved on it, they procured a loan from the Federal Land Bank of Houston, hereinafter referred to as the Federal Bank, and executed their note and deed of trust covering the entire 777 acres to secure same. The amount of this loan was less than the total amount of purchase-money • indebtedness owing to the State Bank. The latter assigned to the Federal Bank a portion of its notes equal to the amount of the loan, constituting the lien of the Federal Bank a first and superior lien to that retained by it. Thereafter Boy-kin and wife executed a deed of trust to S. J. Hicks, trustee, to secure the State Bank in the payment of a promissory note, which note included the balance of the purchase-money notes not assigned by it to the Federal Bank, and also included money loaned by the State Bank to Boykin. This deed of trust covered the entire tract of 777 acres, including the 200 acres which the Boykins designated as their homestead at the time they procured the loan from the Federal Bank. Default having been made by Boykin on his note to the State Bank, the* trustee Hicks advertised the entire tract for sale. Prior to the date of sale, this suit was instituted by Boykin and wife to enjoin the sale in so far as it included the 200-aere tract which had been designated by them as their homestead. Their petition sought a temporary injunction, prayed that same, upon hearing, be made permanent, and further prayed for an order declaring that their homestead was not liable for any part of the debt secured by said deed of trust. The temporary injunction was granted as prayed for, and the trustee Hicks proceeded with the sale as advertised, omitting therefrom the 200-acre homestead tract. The State Bank was the purchaser at this sale.
After the sale, the State Bank and the trustee filed their answer and amended answer, in which they alleged that a portion of the indebtedness secured by their deed of trust was for purchase money, and therefore constituted a valid lien upon the homestead. The bank also, by way of cross-action, alleged that it had paid certain semiannual installments of interest and principal •to the Federal Bank on the note executed by the Boykins and had, received transfers and assignments of the coupons representing such payments; that it was necessary for it to make these payments in order to protect itself. Further allegations were that, in 'the assignment from the Federal Bank to the State Bank, said installments were made a second lien to the lien retained by the former. The prayer was for judgment on these installment coupons and. for a foreclosure of the lien upon the 200-acre tract. The Boy-kins filed a supplemental petition, admitting the payment by the State Bank to the Federal Bank of the installments, but alleging that the 577-acre tract, being the excess above their homestead in the 777-acre tract, was worth more than the amount of the federal loan, and prayed that in its judgment the court order the excess first sold for the satisfaction of the installment payments before resort should be had to their homestead.
*128The trial was before the court without a Jury. There was evidence of payments made by the Boykins to the State Bank from time to time, and the court, applying these payments to that portion of the indebtedness first incurred, and being for a portion of the purchase money of the land, concluded that all of the remaining indebtedness owing by the Boykins to the State Bank was for borrowed money, for which no lien against the homestead existed. Defendant in error has filed no cross-assignments complaining of this portion of the judgment, and therefore, '■for the purpose of disposing of this appeal, the second deed of trust, being the one executed to Hicks, trustee, for the benefit of the State Bank, will be regarded as having been a lien on the excess only.
On the cross-action of defendant in. error, based upon the installment coupons acquired by it from the Federal Bank, amounting to $724.18, it was the opinion of the court below that same constituted a valid lien against the homestead, subject, of course, to the pri- or lien retained by the Federal Bank, and it ■was ordered that said 200-acre homestead tract be sold to satisfy the indebtedness; the court refusing to order any part of the excess sold to satisfy said installments. The Boykins were not satisfied with that portion of the judgment ordering their homestead sold and refusing to order the excess first sold, and have perfected a writ of error to this court to have that action reviewed.
On' original submission this case was not argued orally, and, upon consideration of the briefs and the record, it was our view that difficult questions involving the application of the equitable rules of marshaling assets were presented. We invited oral argument and supplemental briefs. Our invitation was accepted, and we have had the ben'efit of a full presentation of the theories of each party.
The statement of facts discloses that the deed of trust executed to the Federal Bank was introduced in evidence upon the trial of the case, but same was not copied in full in the statement of facts. Plaintiff in error has had a certified copy of this instrument prepared, and, by agreement with defendant in error and by permission of the court, same has been filed here as a supplemental statement of facts. Since the record before us affirmatively shows that this instrument was in fact introduced in evidence below, we think it permissible to file same here as a supplement to the statement of facts, and .we have considered same just as 'if it had been originally copied therein. A consideration of this instrument, to opr minds, solves the problems which have been of doubtful solution. We copy the following therefrom:
“It is agreed that if default be made in the payment of any of the semi-annual installments of the note secured by this deed of trust, the Federal Land Bank of Houston, or its assigns shall have and is hereby given, the right to sell the property herein conveyed, in satisfaction of such defaulted payment, without declaring the whole debt due, such sale to be made upon the same terms and conditions, as to manner of advertisement, time and place of sale, etc., as is provided for in the event said bank exercises its option and declares the whole note due, save and except that where the sale is made because of the default of one or more of the semi-annual payments such sale shall be made subject to the unmatured part of the note secured by this deed of trust, and it is agreed that such sale shall not in any manner affect the unmatured part of the debt secured by this deed of trust, but as to such unmatured part this deed of trust shall remain in full force and effect, just as though no sale had been made under the provisions of this paragraph; and it is specifically agreed that no one sale under the powers conferred in this paragraph -shall exhaust the right of sale under the powers conferred in the first preceding paragraph hereof relating to the maturity of the entire debt, nor shall one sale exhaust the power of sale to enforce the payment, of any subsequently maturing installment, the payment of which may be defaulted, and it is agreed that an assignee holding any installment or installments of the note hereby secured, shall have the same powers as are hereby conferred on the Federal Land Bank of* Houston to request the Trustee named herein, or his successors as herein provided for, to sell the property herein conveyed. * * * If the person or persons obligated to pay the indebtedness hereby secured shall demand that the excess land, if any, over the legal homestead be sold first, then such excess shall bo first sold and the proceeds thereof applied, first: to the payment of the principal and interest due on the part of the debt hereby secured not represented by renewal of purchase money obligations, and, second: to the payment of the balance of the debt hereby secured. And. in the event the proceeds of the sale of such excess land is not sufficient to discharge the entire debt hereby secured, including all costs and expenses legally chargeable, then the homestead tract shall be sold and the proceeds thereof applied to the discharge of the balance of principal and interest due on that part of the debt represented by the renewal of purchase money obligations, together with all costs and expenses legally incurred in the enforcement of this trust, and it is agreed that such sale may be made on the same date and by virtue of the same notice.”
As we construe the language above copied, the parties to the original deed of trust have, by contract, determined their respective rights, in the situation presented by the facts *129of this case. That being true, there is no occasion to resort to the rules of equity governing the rights of the respective parties to marshal assets. These rules of equity are applicable only in- the absence of a contract. Where the parties themselves, as in this ease, have, by contract, fully defined their rights, the court’s duty is limited to an enforcement of the contract as written. The right to assign installment coupons and a portion of the lien securing same is expressly reserved, as is also the right of repeated foreclosures. There can, therefore, be no question of the right of defendant in error to maintain a suit for a foreclosure of a portion of the original lien securing the payment of the coupons assigned to it.
Similarly, the right of the Boykins to demand that the excess land over the legal homestead be sold first is expressly reserved. That right existed against the Federal Bank as to all or any portion of the indebtedness owing to it. The State Bank is suing upon the contract in which that right was reserved. As assignee of the Federal Bank, it acquired only the contractual rights of its assignor. Its capacity in the suit is not so much that of a purchaser of the excess from Boykin as it is that of a purchaser of the lien from the Federal Bank. Its claimed equitable right as the owner of the excess to have the homestead sold first cannot be made to override the prior contractual right of Boykin to have the excess sold first in a suit, as is this one, founded upon the very contract creating Boy-kin’s right. “Equity follows the law.”
It is our opinion that the trial court erred in decreeing a foreclosure alone upon the 200-acre tract, but that the decree should have been as provided in the deed of trust. It is therefore our order that the judgment of the trial court be, and same is hereby, reformed, so.as to decree that the 577-acre excess be first sold, and that, in event the proceeds of the sale of such excess be not sufficient to discharge the entire debt of $724.-18, including all costs and expenses legally chargeable, then the homestead tract shall be -sold and the proceeds thereof applied to the discharge of said judgment. Should the excess sell for more than sufficient to discharge said judgment with costs, the balance shall be paid to defendant in error, but, should resort be had to the sale of the homestead after the sale of the excess, and should the proceeds of the sale of the homestead be more than sufficient to discharge said judgment, the balance shall be paid to plaintiff in error.
Reformed, and, as reformed, affirmed.
