*205The opinion of the court was delivered by
White, J.The decision of this cause involves three questions, two of law, one of fact; they are ;
' First. Where the wife during the absence of her husband is authorized by the judge to contract an obligation, must the absence of the husband at the time of the authorization appear on the face of the authority, and if not, can it be subsequently proved aliunde ?
Second. Is it competent for a wife not separate in property to bind her separate estate or contract an obligation, with the object not of benefiting her husband or the community, but a third person ? If yes, and she be authorized to borrow a given amount, is a contract.by which she borrows a sum greater than the amount authorized binding, and if not, is it also not binding where the sum in excess of the amount authorized results from having charged a rate higher than the maximum of conventio'nal interest, and adding this amount to the principal?
Third. What amount, if any, is due on the note sued on ?
1. The power of the wife to contract during the absence of the husband depends on the- authority of the judge, and where the judge has authorized, we incline to think, in the absence of all proof, we would be justified, under the rule of omnia rite, in presuming that the judge did not act until the absence of the husband was brought to his knowledge, such knowledge being a legal prerequisite to his action. Whether this be true or not, we think that where the proof is affirmatively made, as in this case, that at the time of the authorization of the wife the husband was absent, then the presumption that the judge knew of -the absence, and hence validly authorized, undoubtedly obtains.
2. That a married woman may, with the authority of her husband, or in default, by the authority of the judge, legally contract, provided she do not bind herself for either debts of the community or those of her husband, is no longer a question. Hillings vs. West, 2 A. 1; 10 A. 433 ; Calhoun vs. Mechanics’ and Traders’ Bank, 30 A. 775. That the borrowing by a married’ woman of a sum of money, and the securing the payment of the amount by the mortgage of her separate property, the amount of the loan being by her used in establishing a son-in-law in business, does not come within the rule inhibiting a wife from binding herself -or her property for debts of her husband or the community, is too obvious to require reasoning. The power of the wife to contract depending for its existence on the authority of the husband or the judge, we think it follows as an inevitable result that acts beyond the scope of the authority are unauthorized acts, and hence not binding. It may be true that the power to contract a loán imports power to stipulate interest, under the maxim omne majus coniinet in se minus, but where the law has put a limit on the rate of conventional interest, we *206do not think the power to contract for interest can be by implication-extended to authorize a greater rate than the maximum of conventional interest allowed by law. Grant that it be true that the limitation of conventional interest may be avoided by adding the interest to the principal, the rule would not hold good in a case where the adding of the interest would increase the principal obligation of a-married woman above the amount authorized ; at all events to the extent that the increased principal resulted from interest in excess of the highest conventional rate. To hold the converse, would be implying from the powers to borrow, authority, not to contract for an accessory and resulting obligation, but to exceed the authority, which would at once render imperative the deduction that no authority is necessary. The argument that a wife who contracts under authority is sui juris, and that as persons sui juris can increase the principal obligation as they please, therefore the wife can so do, is fallacious. The wife is only sui juris to the extent of the authority.
Applying these principios, we have the principal of the note $4166 66 instead of $4617 20. The note matured August 6th, 1872, and bore eight per cent interest from maturity. Crediting the payments as they were made, we reach the following statement:
Principal. $4,166 66
Paid August Bth, 1872. 642 00-
Balance due.'. $3,623 66
Interest on balance from August 5th, 1872, to January 15th,
1873 . 128 84
Due January 15th, 1873. $3,752 40
Paid January 15th, 1873. 2,500 00
Balance due. $1,252 40
Interest from January 15th, 1873, to Novémber 18th, 1874.... 184 52
Due November 18th, 1874..’. $1,436 92
Paid November 18th, 1874. 1,000 00
Balance due. $436 92
Interest from November 18th, 1874, to December 15th, 1876. 72 52
Due December 15th, 1876. $509 44
Paid December 15th, 1876. 200 00
Balance due December 15th, 1876, with eight per cent until paid.. $309 44
In making this computation we have fixed the date of the payments, in January, 1873, and December, 1876, as having been made on the 15thf the exact date not being shown. We have also eliminated the sum *207allowed by the plaintiff as interest on the $2500 from date of its payment to the time of the maturity of the note, thinking it the more correct rule to credit the payment at the time it was made.
It is therefore ordered that the judgment below be reversed ; and it is now ordered that there be judgment in favor of the plaintiff, E. B. HollingswOTth, and against the defendant for three hundred and nine 44-100 dollars, with eight per cent interest per annum from December 15th, 1876, until paid ; five per cent attorney’s fees, as stipulated in the act of mortgage ; the whole with recognition of special mortgage on the property described in the act of mortgage referred to in plaintiff’s petition ; costs of both courts to be borne by the defendant.
