This suit was instituted in the Nineteenth district court of McLennan county by E. A. Muhl and wife against Farm & Home Savings & Loan Association of Missouri, a building and loan association, and others to restrain the sale under deed of trust of their business homestead located at Third and Washington streets in the city of Waco. In October, 1926, the appellees, E. A. Muhl and wife, owned the property in question and used it as their business -homestead. They owned the Texas Life Insurance Company a sum in excess of $22,000, secured -by a valid lien on the property. They executed and delivered to C. A. Trautschold a mechanic’s lien contract and note for the sum of $8,000 for certain repairs and improvements to be made on the property in question, and shortly thereafter made application to the appellant Farm & Home Savings & Loan Association of Missouri for a loan on said property in the sum of $30,000 for the purpose of taking up and extending the mechanic’s lien inr debted-ness of $8,000 and the indebtedness to the Texas Life Insurance Company of $22,000. The loan was accepted by the appellant. The $8,000 note and contract lien held by Traut-schold and the $22,000 and lien held by the Texas Life Insurance Company were assigned by the respective owners thereof to the appellant, and the appellees then executed and delivered to the appellant a new note in lieu thereof in the sum -of $30,000 for the purpose of talcing up and extending the balance due on said notes. The $30,000 note was secured by deed of trust on the property in question, and the interest thereon was payable in monthly installments. At the time of the making of the loan in question the appellees subscribed for certain stock in the appellant association, as was required by its rules. In 1929 t-he appellant declared the note due for failure to pay the installments thereon and was proceeding to sell the property under the power given in the deed of trust. The appellees filed suit to restrain the sale under the deed of trust, and alleged, among other things, that the improvements called for in the mechanic’s lien contract securing the payment of the $8,000 payable to Trautschold were never fully completed as -therein provided; that there was no consideration for the transfer of said note from Trautschold to the appellant; that the money advanced by appellant to take up said note was not used to pay for the improvements on the premises in question, but that a part thereof was used for other- purposes and a part thereof converted by the appellant to its own use; and that the contract securing the payment of the $30,000 was tainted with usury.
A trial was had before a jury. At t-he conclusion of the evidence, the court, with the consent of the appellant but over the protest of the appellees, discharged the jury and rendered judgment thereon without the aid of the jury. The court, however, after discharging the jury and hearing argument in the case, concluded that out of the money advanced by appellant on the $30,000 note executed by Muhl and wife to the loan association, $22,000 was used to take up the loan held by the Texas Life Insurance Company and only the sum of $1,780.65 of the balance was used in paying for the improvements done under the mechanic’s lien contract in favor of Trautschold, and that .the balance thereof was used for other purposes and was therefore not secured by a valid lien on the property in question. After allowing credit for certain payments made by the appellees, the court rendered judgment for the appellant against the appellee E. A. Muhl for $17,793,28, together with foreclosure of the lien on the property in question against E. A. Muhl and wife, and rendered a personal judgment in favor of appellant against E. A. Muhl for the sum of $7,245 as unsecured by said lien, and ordered the property sold under order of sale for the purpose of paying that part of tne *319judgment secured by said lien. Tbe judgment was otherwise in favor of the appellees, in that it perpetually enjoined the appellant from selling the property in question under the power given in the deed of trust. The Farm & Home Savings & Loan Association of Missouri has appealed, and the appellees E. A. Muhl and wife have filed cross-assignments of error.
As stated above, the suit by Muhl and wife was for an injunction to restrain the sale of the property under the power given in the deed of trust. The appellant, in its answer, did not pray for a judgment against the appel-lees for its debt, nor for foreclosure of its lien, but merely asked that the amount of its debt be fixed and that it be allowed to sell the property under the deed of trust. Both parties complain of the action of the court in rendering personal judgment for the appellant against the appellee Muhl and in foreclosing the lien on the property in question. There were no pleadings to support such judgment. The appellant preferred to foreclose its lien under the deed of trust so as to cut oft the equities of any junior lienholders claiming an interest in the property. A sale under the deed of trust would cut off such claims, whereas, if the property was to be sold under an order of court, it would be necessary for the appellant to make such lienholders parties to the • suit in order to destroy their equities of redemption. The judgment of the trial court must find support both in the pleadings and in the evidence, and where there are no pleadings to support such judgment it is unauthorized. It was error, therefore, for the trial court to enter a personal judgment for appellant for its debt with foreclosure of its lien for a part thereof.
The evidence shows that the improvements as called for in the mechanic’s lien contract were never fully completed as therein provided, and the appellees contend that by reason thereof the lien never became fixed on the homestead property. The appellant contends that appellees are estopped to set up such defense herein. The mechanic’s lien contract in favor of Trautschold was in the regular form, signed and acknowledged by the husband and wife, and recited that it was given to secure the payment of the $8,000, and that the contractor, in consideration therefor, was to do certain improvements on the premises in question. The deed of trust subsequently executed by ap-pellees to the appellant to secure the payment of the $30,000, recited that said note was given at appellees’ request to take up and extend a balance of $22,000 held by the Texas Life Insurance Company and secured by a valid lien on the property, and the $8,000 due Traut-schold under the mechanic’s lien contract. It recited that the improvements as called for. in the mechanic’s lien contract had been completed as called for therein and had been accepted by the appellees and that the note was secured by a valid lien on the property. The transfer of the $8,000 note and lien from Trautschold to appellant recited that the improvements had been completed as provided in the contract and that they had been accepted by Muhl and wife. At the time the loan of $30,000 was secured from appellant, the ap-pellees, executed and delivered to appellant their affidavits in which they stated that they were the persons who had given the mechanic’s lien note and contract for improvements on their homestead, and that the material had been furnished and the work had been completed by the contractor in full compliance with the terms of said contract and accepted by them. Trautschold made a similar affidavit. The -officials of the association testified that they believed and relied on the representations made in the deed of trust and in the affidavits. Lee Lockwood, the local agent of the association, testified that he believed the' statements contained in the affidavits and thought they were the truth and that nothing had been said to him that would in any way cause him to believe that the improvements had not been so completed. There is nothing in the record to show that the association or its agents knew that the improvements had not been made as represented. E. A. Muhl testified that he knew the property was his homestead and that it was necessary to put the mechanic’s lien on the property, before the loan could be made. He could read and write, and there was nothing to prevent him from reading the various instruments. He further testified:
. “I signed that affidavit because we had to go ahead with the loan, and I figured to get the $30,000.00. That is the reason I signed it. I figured to get it.”
Mrs. Muhl testified that she could read and write and that she signed the papers. There was nothing to prevent her from reading them. The appellees did not allege that they were prevented from reading the papers nor that, they were caused to sign them through fraud, accident, or mistake. Wé think the evidence shows without dispute that the association purchased the $8,000 mechanic’s lien note and made the loan of $30,000 on the property in renewal of this note and the balance of $22,000 held by the Texas Life Insurance Company in the belief that the statements contained in the deed of trust and the affidavits were time and that the improvements had been made as provided for in the mechanic’s lien contract.
It is the contention of the appellees that since the improvements were never fully completed according to the contract, the attempt to create the lien on the homestead was void. This proposition, however, does not take into consideration the well established doctrine of estoppel. Ordinarily the erection of the improvements as per the terms of the contract is a necessary prerequisite to the creation of a valid mechanic’s lien on the homestead, but where the husband and wife have *320by their conduct led an innocent third party to believe that a valid lien has been created1 on the homestead and such a third party is; caused to invest his funds on the faith and credit of such lien, the husband and wife are estopped as to such third party to plead tha^ the lien is invalid. The homestead laws of; this state are favorites of the courts,'and a> liberal rule will be employed to protect the! homestead f-rom forced sale; but it was never intended by the framers of the Constitution that the homestead law 'should be used as an instrument to defraud an innocent third par-; ty. The appellees having, by their conduct,: led the appellant to believe that a valid lien existed on their homestead to secure the payment of the notes taken up by the association, and the association having purchased said note in good faith before maturity, are now estop-ped to plead that the lien is invalid. Garrett v. Katz (Tex. Civ. App.) 23 S.W.(2d) 436, and cases there cited; Pickett v. Dallas Trust & Savings Bank (Tex. Com. App.) 24 S.W.(2d), 354; Graves v. Kinney, 95 Tex. 210, 66 S. W. 293; Welborn v. Earle (Tex. Civ. App.) 268, S. W. 982; Barron v. Theophilakos (Tex. Civ. App.) 13 S.W.(2d) 739.
The appellees further contend that there was no consideration paid by the association to Trautsehold for the §8,000 note, and further that the appellees never received from the association the full $30,000. With reference to the first contention the evidence shows that' Trautsehold wa-s a kinsman of E. A. Muhl and that at the time he signed the assignment of the note to the appellant he stated that id would be satisfactory with him rto deliver the money directly to Mr. Muhl. In addition to this, Trautsehold is not a party to this suit and is not pleading failure of consideration fori the assignment of this note.
With reference to the second contention, that is, that the appellees did not receive from .the association the full benefit of the $30,000 evidenced by the note in question, the evidence shows that a check for $30,000 was made out, to E. A. Muhl, and R.- L. Dockwood, who was the local agent of the association, and for-; warded to Lockwood. Muhl indorsed the' check to Lockwood, who in turn, deposited the] same in his bank. Lockwood with Muhl’s con-| sent delivered a check in the sum of $22,000 to the Texas Life Insurance Company in pay-) ■ment of the balance of the loan held by that company and being taken up by the appellant. He gave Muhl checks for $6,500 and retained in his possession the balance of $1,500 to pay an account that he held against Muhli in the sum of $1,529.25. This account consistí ed, among other things, of two advance pay-; ments made to the association by Lockwood at' Muhl’s request, insurance, premiums, ab-j stracts, fees, etc. All the items of this account] were obligations of Muhl’s and he authorized] the payment of same.
The appellees claimed that after the checks for $6,500 were delivered to him, that Lockwood caused appellee Muhl to sign a ;blank check, and that afterwards, without his consent, this check was filled out for the sum of $4,719.35, and delivered to the Texas Life Insurance Company, and that by reason thereof Lockwood, as agent for the appellant, had enabled the life insurance company to convert said money to its own use, and that by reason .thereof he should have credit on the note here involved for that amount-. It seems that Muhl actually owed the Texas Life Insurance Company more -than $22,000. According to his own testimony, after he signed the blank check he went with Dockwood to the office of the insurance company for the purpose of taking up the loan held by the insurance compa'ny. He .stood there and saw the officials of ]the insurance company figuring up the amount '.that he actually owed the company. He says, however, that he did not know what they were doing. The parties all then went back to the bank where appellees’ money had been deposited. He testified:
“I went with Mr. Lockwood and someone out of that bank, the insurance company bank, back over to the Eirst State Bank and they cashed my check, that cheek there, the way I understand it. The First State Bank & Trust Company evidently cashed this check for $4719.35 and paid out the money because we went back and they gave me some notes and securities I had at that bank.”
He further testified:
"Relative to whether it is or is not a fact that I know, and knew at that time, that Mr. Dockwood paid the Texas Life Insurance Company $22,000.00, and that on the same day I paid them $4,719, and some odd cents .additional, as represented by the cheek that ⅞ identified which Mr. Dunnam introduced in evidence here, I will state that I was there with him when it was paid, but I didn’t pay it. I was there when it was paid, but I did not know that that amount was paid. I knew at that time that Mr. Mayfield was claiming that I owed the Texas National Bank more than $22,000.00. I saw part of this cheek madé out for $4,719.00.”
There is testimony in the record that ap-pellee gave the Check in question directly to .the Texas Lifel Insurance Company in payment of the additional indebtedness owing by him. It is apparent from appellees’ own .testimony that the money in question was used for his use and benefit by and with his consent. Moreover, all of the money so placed in appellees’ bank account consisting of the $6,500 above referred to was checked out by appellee Mu'hl and the hank account closed in 1927. The cheek for $4,719.35 had been given on this account. He made no complaint on account of this sum having *321been cheeked out of bis account until tbe year 1930. His long silence in this respect is strong evidence of bis acquiescence and approval thereof. We do not understand that it was incumbent on tbe appellant to see that every dollar of tbe identical money advanced by it was paid directly to tbe contractor who constructed- tbe improvements. Tbe appellee bad paid some of tbe bills for tbe work done and was entitled to reimburse bimself out of tbe funds in question. Turbeville v. Book (Tex. Civ. App.) 226 S. W. 814. Tbe appellees therefore received tbe full benefit of the $30,000 advanced by appellant.
Tbe appellees, by cross-assignments of error, contend that the loan in question was tainted with usury. As before stated, tbe appellant is a building and loan association and at tbe time of tbe making of tbe loan in question, tbe appellees subscribed for 30Q shares of stock in the appellant association. Tbe subscription contract bound tbe appel-lees to pay monthly installments of $150 on tbe purchase price of the stock, and under tbe rules of tbe association, if such installments were not paid as they matured, tbe purchaser was required to pay a charge of 1 per cent, per month assessed, on tbe amount of dues on each $100 par value of such stock delinquent and unpaid, and in addition tbe association was authorized to charge interest at the rate of 1 per cent, per month on delinquent interest due on tbe $30,000.
Tbe charge of 1 per cent, per month on delinquent installments on tbe stock purchased was authorized by article 869, Revised Civil Statutes 1925, and was entirely separate and distinct from tbe interest on tbe loan in question. It was not a penalty for tbe detention of tbe money borrowed by tbe appellees and did not in any sense constitute usury. Geisberg v. Mutual Building & Loan Association (Tex. Civ. App.) 60 S. W. 478; Interstate Building & Loan Association v. Goforth, 94 Tex. 259, 59 S. W. 871.
The charge of interest at tbe rate of 1 per cent, per month on delinquent interest, if standing alone, would be usurious. But this charge must be taken in connection with tbe rate of interest on tbe principal. Tbe principal bore interest at the rate of 7.8 per cent, per annum. Tbe monthly installments of interest as they matured became a part of the principal, and, if tbe contract bad not otherwise provided, would have borne tbe same rate as tbe principal. Bothwell v. Farmers’ & Merchants’ State Bank (Tex.Sup.) 30 S.W.(2d) 289, par. 2. By adding tbe sum to be collected as interest on tbe delinquent interest at 1 per cent, per month to tbe sum-to be collected as interest on tbe principal at 7.8 per cent, as provided in tbe contract, the total rate of interest on tbe entire loan will never exceed 10 per cent, peí-an num. Moreover, tbe deed of trust in question expressly provided that under no circumstances should tbe obligors ever be required to pay interest on tbe loan in excess of 10 per cent, per annum. Tbe contract was not usurious.
Appellees contend that the appellant was not entitled to maintain its cross-action herein, because it did not allege and prove that it had a permit to do business in Texas at the time the suit was filed, and further that it bad complied with all tbe provisions of title 24, Revised Civil Statutes 1925 (article 852 et seq.), regulating building and loan associations, and prescribing tbe prerequisite for tbe securing of such permits. The appellant was a foreign building and loan association incorporated under tbe laws of tbe state of Missouri. Appellant did allege and prove that it toad a permit to do business in this state from tbe year 1919 to 1929. The contract sued on was made in 1926. The statute does not require a foreign corporation to have such a permit at tbe time of tbe filing of tbe suit, but only requires that it have such permit at tbe time the “contract was made or tort committed.” Revised Civil Statutes 1925, article 1536 ; Kingman Texas Implement Co. v. Borders (Tex. Civ. App.) 156 S. W. 614; Security Co. v. Panhandle National Bank, 93 Tex. 580, 57 S. W. 22. Where a sworn public official, acting within line of bis duty, does an act which presupposes tbe existence of certain facts necessary to make bis act legal, bis act is presumptive proof of tbe existence of such fact. He will be presumed to have acted lawfully. Lewis v. Heath (Tex. Civ. App.) 12 S.W.(2d) 641, par. 4; Miller Mfg. Co. v. Coleman (Tex. Com. App.) 29 S.W.(2d) 991, par. 1; 22 R. C. L., page 474. Since tbe secretary of state issued to appellant a permit to do business in this state, it will be presumed that tbe appellant complied with all tbe necessary prerequisites as prescribed by Revised Civil Statutes 1925, title 24, regulat- • ing building and loan associations. If tbe question could be raised at all in this proceeding, the burden was clearly on tbe ap-pellees to both allege and prove tbe absence of tbe necessary facts authorizing tbe secretary of state to issue tbe permit. Supreme Council v. Story, 97 Tex. 264, 78 S. W. 1; Independent Order of Puritans v. Brown (Tex. Civ. App.) 229 S. W. 939, at page 944.
At the time appellees secured tbe loan in question, they assigned to appellant tbe rents to accrue from.tbe mortgaged property to secure the payment of the loan. Tbe appellant alleged the execution and delivery of tbe assignment;. that the property was inadequate to pay its debt; and that if a receiver was not appointed, appellant would suffer irreparable injury. There was no proof, however, as to the value of tbe security. Tbe appellant prayed for tbe appoint*322ment. of a receiver to take charge of the rents. Since the rents were pledged as security for the payment of the debt, and the appellees had defaulted in the payment thereof, the appellant was entitled to have a receiver appointed to take charge of and hold the rents for the purpose of liquidating its claim. Revised Civil Statutes 1925, article 2293; De Barrera v. Erost, 33 Tex. Civ. App. 580, 77 S. W. 637; Citizens’ State Bank v. First National Bank, 56 Tex. Civ. App. 515, 120 S. W. 1141; Cotton v. Rand (Tex. Civ. App.) 92 S. W. 266. 42 C. J., page 123, § 1688.
. It is apparent from what has been said that the appellant is entitled to have the amount of its debt established and that it should be permitted to sell the property in question under its deed of trust in satisfaction of its indebtedness. The amount of appellant’s debt is the $30,000 as evidenced by. the note in question, together with the accrued interest thereon, and insurance premiums advanced by it, less the payments heretofore made by the appellees. The trial court found that the appellees had paid the sum of $8,688. This was the maximum amount claimed by appellees. Applying these payments as they were mlade, appellant’s debt on January 28, 1930, at the time the last payment was made and after deducting all credits to which appellees were entitled, amounted to $30,715. Appellant is entitled to interest from that date at the rate of 7.8 per cent, per annum.
The judgment of the trial court is therefore reversed, and j'udgment here rendered for appellant fixing its indebtedness at the sum of $30,715, with interest thereon from January 28, 1930, to date at the rate of 7.8 per cent, per annum and that appellees take nothing. The temporary injunction heretofore issued by the trial court restraining the sale of said property under the deed of trust is hereby dissolved. The trial cburt will, upon application of the appellant, appoint a receiver for the purposes hereinabove indicated.
