This is a case of an option or what is sometimes called bonding a mine. The owners of the mine, defendants herein, desiring to sell their mine, entered into a written agreement, in form of a penal bond, with plaintiffs, that upon payment by them to defendants at a future day, of a stipulated sum of money, defendants would convey to plaintiffs their mine. This agreement is in writing, is certain and fair in all its parts, is capable of being performed, and is under defendants’thand and seal. Plaintiffs signed no agreement. Upon the day stipulated in said agreement, plaintiffs tendered the sum of money agreed upon and demanded the mine; defendants declined the money, and refused to comply with their agreement. Plaintiffs bring this suit in equity, and ask the court to enforce the contract. Defendants demur to plaintiffs’ bill for want of equity and set up as specific ground of demurrer that the bill does not show upon its face what the consideration was, if any, that defendants had or were to receive for entering into the contract to convey; also that there was no mutuality; that the contract.was unilateral; that defendants alone were bound. The court sustained the demurrer, and plaintiffs appealed.
To the first point, it is sufficient to say the contract being under seal, imports a consideration; to sustain the demurrer on the ground that there was not a valuable consideration was not only assuming the fact but also depriving the plaintiffs of an opportunity of proving a consideration. The contract being under seal, we must presume that there was a valuable consideration till the contrary is shown. The court, in sustaining the demurrer, prevented the plaintiffs from doing this.
As to the second point, the condition of mutuality is, in general, sufficiently satisfied if there be any consideration of the one side as well as the other. It is also held that a court of equity, in actions for the specific performance of optional contracts and covenants to lease and convey lands, will enforce the covenant, although the remedy is not mutual, provided it is shown to have been upon a fair ' consideration. So it is also held not to be necessary to the specific performance of a written agreement that it should be signed by the party seeking to enforce it. If the agreement is certain, fair, and just in all its parts, and signed by the party sought to be charged, that is sufficient. The want of mutuality is no objection to its enforcement. The very nature of an option is unilateral; one party has property to sell, the other has only, perhaps, ability to make sales. The skill and ability of the one is the consideration which induces the other to bond the mine. If the agreement is fair in every respect, and neither party was deceived in making it, there can be no objection to enforcing it. There is certainly sufficient mutuality to support it, if we take the facts, as stated in the bill, to be true, and this the demurrer does. See 5 Wait’s Act. & Def. 788, and authorities there cited.
We are of opinion that the court below erred in sustaining the demurrer, and the case is remanded for further action in accordance with this opinion.
Bell, J.This is an appeal from a judgment of the court below •sustaining a demurrer of the defendants to a bill in a suit for specific performance. The suit iá brought for the specific performance of what is claimed in the bill to be a contract to convey an interest in a -mining claim, situated in the Lake Yalley mining district, in the county of Grant, executed by one William Mead to the grantors of the plaintiffs. The instrument is one that is commonly called a mining bond. The defendants demurred to the bill, and set forth as grounds of their demurrer—First, that the said bill contains no matter of equity whereon this court can ground any decree, or give complainants, or either of them, any relief against defendants, or either nf said defendants; second, upon the facts stated in the said bill, the complainants have a plain, adequate, and complete remedy at law for their alleged grievance, if any they have; third, the bond, memorandum in writing, contract, and agreements referred to in said bill, and upon which the said suit is professedly founded, is without consideration or mutuality between the parties thereto, and imposed no valid, binding, or equitable obligation on the -defendants which the court will enforce.
We shall not consider the first ground of demurrer separately, as it is disposed of by the reasoning applicable to the other two grounds, which we proceed to consider.
We do not think that the second ground or cause for demurrer is well founded. We do not think that the plaintiffs have a plain, adequate, and complete remedy at law for their alleged grievance. In considering the question we are called upon to determine, if possible, what the real intent of the parties was at the time of the execution of the instrument in question. It seems entirely clear to us that at that, time the intent of the parties was that the plaintiffs’ assignor should be entitled, upon the payment of the sum of $3,300 within the time limited to the defendant Mead, to a good and sufficient conveyance of a one-third interest in the property referred to in the instrument. This intent is, we think, fairly to be inferred from an inspection of the instrument itself; and, in the absence of any proof of fraud, undue influence, or want of actual consideration, the instrument is-binding and valid, and can be enforced by a decree of a court of equity. That a court of equity has power to decree specific performance of such an instrument is well settled upon the best authority.
In the case of Ensign v. Kellogg, 4 Pick. 1, the court says, “we are satisfied that no subject is more proper for the power of a court of chancery in decreeing specific performance than a contract for the sale of real estate; for what is agreed to be done ought in conscience to be done, nor is the remedy at law for damages complete or adequate, for the thing contracted for is wanted,—and the value in money may often be unsatisfactory compensation.”
That case was one brought upon a bond in a penal sum conditioned for the conveyance of certain real estate upon the payment-of a stipulated price. In that ease, a part of the consideration was paid upon the making of the bond, and the remainder on the last day named in the condition, and in the case at bar the consideration for the mine was tendered within the time limited by the condition of the bond, and is to be regarded in law as paid when tendered. Upon this subject Judge Story says: “What these courts seek to be satisfied of, is that the transaction. in substance amounts to, and is intended to be, a binding agreement for a specific object, whatever may be the form or character of the instrument. Thus, if a bond with a-penalty is made upon condition to convey certain lands upon the-payment of a certain price, it will be deemed in equity an agreement to convey the land at all events, and not to be discharged by the payment of a penalty, although it has assumed the form of a condition only. Courts of equity, in all cases of this sort, look to the substance of the transaction and the primary object of the parties; and, where that requires a specific performance, they will treat the penalty as a mere security for its due performance and attainment.” 1 Story, Eq. Jur. § 715; citing numerous authorities in support.
In the case of Dooley v. Watson, 1 Gray, 414, Chief Justice Shaw says: “The promise of the defendant to pay plaintiff one hundred dollars, if the defendant should fail to perform his agreement to convey the land, was a mere security for the performance of that agreement. Courts of equity have long since overruled the doctrine that a bond, for the payment of money, conditioned to be void on the conveyance of land, is to be treated as a mere agreement to pay money. When the penalty appears to be intended merely as a security for the performance of the agreement, the principal object of the parties will be carried out.”
It seems to us, upon principle, and upon careful examination of the authorities cited, that, in the suit at bar, it was clearly the intention of the parties that the plaintiffs’ assignor should have a right to-a conveyance of the property, and should not be relegated to his action at law upon the bond for damages; and that that was the principal object of the parties, and should be carried out.
We come now to consider the third ground of demurrer, which is that the bond, memoranda in writing, contract, and agreements referred to in the bill are without consideration or mutuality between the parties. We shall have to treat the questions of consideration and mutuality separately. And first as to consideration: The instrument itself, which is the basis of the suit, is in the form of a bond. It is under seal. Can it be urged, upon demurrer, that such, an instrument is without consideration ? We think not. The seal imports consideration. It imports valuable consideration. In a case-at law the presumption of consideration is so strong the defendant, would be estopped from denying it, or offering proof tending to impeach it. In a ease in equity this presumption of consideration, imported by the seal, still remains; and, while in such a suit the court will permit a party to rebut that presumption by proof of the facts,, yet, until the presumption is met by an answer alleging the actual want of consideration, it must stand, and a party will not be permitted to say of an instrument executed by him, and under seal, that no-consideration is shown upon its face. We are therefore of opinion that the question of want of consideration is not properly before us-on the demurrer, and for that reason the .demurrer must be overruled.
We now come to the question of the alleged want of mutuality between the parties. This is a question of some difficulty, and its meaning appears to have been variously understood by the courts. Parsons, in his Work on Contracts, has collated the authorities in a note appended to page 409 of vol. 3 of the sixth edition. Reference to some of these cases is pertinent here: “The meaning of the rule of equity requiring that contracts must be mutual, is not very clear; nor is it easy to make a classification of the cases in which-it has been announced as the ground of decision. By mutuality seems sometimes to be intended mutuality of remedy, in other cases mutuality of agreement; and in neither sense is the rule of universal application. Southeastern R. Co. v. Knott, 10 Hare, 122; 17 Eng. Law & Eq. 555. It is now perfectly established that a purchaser may compel a conveyance, although the vendor could not have enforced specific performance because of some infirmity in the title. Sutherland v. Briggs, 1 Hare, 34. And in cases within the statute of frauds, it is now clear (although a contrary opinion upon this point was expressed by Lord Bedesdale) that the circumstance that the defendant only signed the agreement so that he could not have compelled the plaintiff to perform it, constitutes no good ground of objection to the plaintiff’s suit. ” Backhouse v. Mohun, 3 Swanst. 434, n., and other authorities cited.
In one case cited in the note in question, it was held that the plaintiff’s filing a bill for specific performance is a sufficient assent to remove an objection of want of mutuality. Goodwin v. Lightbody, Daniell, 153. See Field v. Boland, 1 Dru. & Wal. 46.
The case of Stansbury v. Fringer, 11 Gill & J. 149, strongly supports the views above expressed. There it was agreed between A. and B. that A. should hold certain lands of B. for a term of years, paying taxes and making certain improvements; and it was further agreed that A. might at any time during the term, at his pleasure, become the purchaser of the land, at a stipulated price, and A., having tendered the price, filed a bill to compel B. to make the conveyance. It was objected, that the contract was not mutual, because there was no obligation to purchase upon the plaintiff; but the court held that by occupying the land, paying taxes, and making the stipulated improvements, he had given a consideration for his privilege to purchase the land, and specific performance was decreed.
In the case of Western R. R. v. Babcock, 6 Metc. 346, it appears that the owner of a certain parcel of land entered into an agreement under seal with the railroad company, by which he granted them the privilege of running their road through his land, upon payment of a certain compensation for the soil appropriated and the damage occasioned. In the bill filed by the company for a specific performance, it was contended that the contract wanted mutuality inasmuch as the plaintiffs were under no obligation on their part to take the land or pay the price. But the objection was overruled. From a portion of the opinion of Chief Justice Shaw in this case, it can be inferred that it was held that a positive agreement existed on the plaintiff’s part to act under the contract, where in the event of his acting under it, there will be a certain obligation upon him to pay a consideration,— in other words, that the license to act is sufficiently supported by the promise to pay for using the license in case he does use it. The circumstance that a substantial consideration did not need to be shown at law, the contract being under seal, was also adverted to.
The doctrine of the common law that mutuality is only necessary where the want of mutuality would leave one party without a valid or available consideration for his promise, seems to express all the mutuality in the agreement of the parties as distinguished from reciprocity of remedy that equity requires as a necessary condition to a specific performance. “It is the general rule that where the obligation to perform rests upon one of the parties only, equity will enforce the contract.” Van Doren v. Robinson, 1 C. E. Green, 256. But in the same case the chancellor held that “the principle does not apply when the contract, by its terms, gives to one party a right to the performance which it does not give to the other; as where a lease contains a covenant on the part of the lessor for a renewal of the lease at the expiration of the term. It is now settled that such a covenant may be enforced against the lessor, though there is no reciprocal obligation on the part of the lessee to accept the renewal. ” Citing Fry, Spec. Perf. § 948. Such a contract being founded on ■considerations, can and should be enforced, when it was evidently the intent of the parties, as in this ease, to give to the obligee the right to take the property upon the payment of the stipulated price. The question of the consideration we have already passed upon.
In the case of Green v. Richards, 8 C. E. Green, 32, the following paper was held to be a contract which could be specifically enforced:
“Beceived from Mrs. Catherine Green one hundred (100) dollars on account of payment on house No. 71 Perry street; due on account of rent, one hundred and twenty (120) dollars.
[Signed] “Thomas E. Bichards.”
Indorsed on the foregoing receipt was the following:
“This is to show that I agree to sell to Mrs. Capt. Green the house ■and lot No. 71 Perry street, for the sum of twenty-five hundred (2,500) dollars; and that when there is five hundred (500) dollars paid, and the back rent, I will give her a deed, and take a mortgage for two thousand (2,000) dollars.
' [Signed] “T. E. Bichards.”
The chancellor in this case says: “This is a contract certain and ■definite as to the subject-matter, the price, and the condition precedent. * * * This agreement does not come within the decisions which hold that an agreement to entitle to specific performance must be mutual, and such that the defendant could have had that remedy. These decisions themselves are controverted and conflicting. But they do not apply to a case where the complainant has paid a part or the whole of the consideration, or a consideration for the defendant signing the agreement; or to a ease of a lease for years, with the option of purchasing during the term; or to cases where the contract, by its terms, gives one party a right to the performance which it does not give to the other; citing Van Doren v. Robinson, supra. In Buch cases specific performance is constantly decreed.”
In a well-considered case in the same state (New Jersey) Chancellor Pennington says in a ease for specific performance upon a unilateral contract: “The complainant did not, indeed, sign the paper, (an instrument under seal to convey land,) and it was never intended that he should; but the papers contain conditions on his part which the evidence shows he faithfully performed. The case is this: A party signs an agreement to do certain things, after the other shall have performed on his part conditions which are precedent; these conditions being performed, upon requiring the party who signed the agreement to fulfill his part, he says, ‘I am not bound, because you never signed the agreement.’ I can see no propriety in such a view of the ease. There was mutuality in the very terms of the agreement.” Laning v. Cole, 4 N. J. Eq. 229. Optional contracts are not favored in equity, though if founded on consideration and free from objection in other respects, are enforced. Pinner v. Sharp, 23 N. J. Eq. 274. Any sufficient consideration' would make such unilateral contracts binding in equity. 10 C. E. Green, 554. See, also, Reynolds v. O'Neil, 11 C. E. Green, 223.
Upon all authorities above cited and upon principle, we see no reason why a person may not, for a good consideration, bind himself to do a thing, though he has no reciprocal remedy against the person to whom he is bound. If such unilateral agreement is based upon good consideration, and there be no other objection to it, we think that it should be enforced. In the case before us, it does not appear but that there was a perfectly valid consideration; one is presumed, as we have’already decided, upon the record before us.
I have dwelt thus at length upon the subject of alleged want of mutuality, because my learned associate, in his opinion in the court below, principally bases the result arrived at there, upon the fact, that because there was no promise to pay, or actual payment and acceptance, there was no mutuality and no completed contract that equity would enforce. That opinion seems to have been based upon a dictum of Judge Hallett in the case of Smith v. Reynolds, 8 Fed. Rep. 696. The judge in that case, which was one brought upon a similar instrument to the one before us, but where the question was before him upon an exception to the answer setting forth want of consideration, and not upon a demurrer, seems to have proceeded upon the assumption that no case could be maintained upon an instrument unless there was a reciprocity of remedy7. He cites no authorities, but says: Was it possible that one party could be bound to sell, while the other party was not bound to buy ? He does not pretend to have considered the law with care; for he adds, that at the final hearing, and upon a more extended examination of the authorities, his views might be modified. After all, the question before Judge Hallett was, whether or not an answer to an action for specific performance upon an instrument similar in form to the one at bar, setting up want of consideration, was a good answer, and he holds that it was. I am of the opinion that he was right, but this case does not come, before us upon that question.
The case of Gordon v. Darnell, 5 Colo. 302, was also relied upon in the court below as upholding the doctrine that such an instrument as is here sued upon, is void for want of mutuality. A careful examination of that case does not sustain the position. The court in that case says, in regard to an instrument similar in its character to the one before us, “until acceptance by the obligee or the performance-of some act equivalent to an election to purchase under the terms mentioned therein, it is nudum pactum. Its legal effect is that of a continuing offer to sell, which is capable of being converted into a, valid contract by a tender of the purchase money, or performance of its conditions, whatever they may be, within the time' stated and before the seller withdraws the offer to sell.” It therefore holds that such a contract becomes binding, at least, if within the time limited the party desiring to purchase makes tender of the purchase money. We simply go further and say that such a contract, if based upon good consideration, is binding upon the obligor until the time limited by its terms has expired and there has been a failure on the part of the obligee to avail himself of the privilege granted.
It follows, from the views here expressed, that the judgment sustaining the demurrer below should be reversed.
