The opinion of the court was delivered by
Poland, J.The history of this case is substantially the following. On the nineteenth day of January, 1828, the defendant Wright was the owner of a certain farm in Pittsford, and on that day he executed a mortgage of the same to Francis Slason, to secure the payment of two notes, both amounting to the sum of five hundred dollars. On the eighteenth day of August, 1829, Wright executed another mortgage of the same land to Reuben R. Thrall, to secure the payment of a note of $482,70; and at some subsequent time, which is not stated in the papers, Wright conveyed the same premises to Thrall by an absolute deed. Subsequently (but at what time the case does not show) Thrall conveyed the same premises, by deed with warranty, to William Wheeler; and in July, 1840, Wheeler conveyed the same by deed with warranty to the defendant Leach. At the time of the conveyance from Wheeler to Leach, Slason executed to Leach a bond, in which he covenanted to save him harmless against all cost and damage in consequence of any previous incumbrance upon said farm. Slason afterwards, on the twenty seventh day of January, 1842, assigned to the orators his mortgage deed and notes from Wright.
The orators concede, that the effect of the bond given by Slason to Leach was, to release the land from the burden of his mortgage; and we have no doubt, but such must be its operation. It is much like the case of a covenant not to sue, which has always been held equivalent to a release, or discharge; for the law would countenance no such absurdity, as to allow one man to maintain an action to recover lands, or damages, and then permit another suit to recover back the same thing; it therefore allows the defence to be made in *266the first instance, to avoid circuity of action. 1 U. S. Digest 678. 7 Mass. 155. 15 Ib. 112. 16 Ib. 24 17 Ib. 72S. 1 Cow. 122. 8 Johns. 54.
It is, however, insisted by the orators, that at the time the bond in question was executed and delivered by Slason to Leach, the parties to it did not understand, what the legal effect of the bond would be upon Slason’s mortgage; and they allege in their bill, that at the time of the execution of the bond by Slason to Leach, it was understood and agreed between them, that Slason was to have the full benefit of the covenants in the deed of Thrall to Wheeler, and in the deed from Wheeler to Leach, and to have the right to pursue any proper remedy, either at law, or in equity, in his own name, or that of Leach, to enforce said covenants.
It might admit of serious doubt, perhaps, whether, upon the evidence in this case, the fact of such understanding and agreement was established between Slason and Leach, inasmuch as Leach directly denies in his answer, that there was any such understanding between them, and his answer is only contradicted by the testimony of one witness, and that of the admissions of Leach merely. Wheeler, in his answer, says, there was such an agreement; but that, of course, cannot be used as evidence against the other defendants in the case. The manner in which the business was done has some tendency, however, to support the belief of what the orators claim to have been the understanding of the parties to the bond, at the time of its execution, and in deciding the case we are disposed to consider the case as proved in favor of the orators, upon this point.
The orators admit, that Slason intended, when he executed the bond to Leach, to release the land, in Leach’s hands, from the incumbrance of his mortgage, and to discharge Leach from any liability to him ; and that Leach, relying upon Slason’s bond, purchased the farm of Wheeler, which otherwise he would not have done; and it is not now insisted, that the bond has any other or different effect, so far as the defendant Leach is concerned, than was intended by Slason himself; and neither is it claimed, that the court of chancery ought to. interfere, as between Slason and Leach. The orators’ claim is, that, by the agreement between Slason and Leach, at the time the bond was executed, Slason was to retain all *267his rights against the previous parties, and was also to have the benefit of Leach’s remedy against Thrall and Wheeler, upon the covenants in their respective deeds.
It may not be improper to consider for a moment, what rights either Slason, or Leach, had, as against the previous parties in the chain of title. Slason had his mortgage and notes against Wright, and he might pursue the mortgage upon the land, or he might look to Wright personally upon his notes, without regard to the mortgage. His only right, or remedy, as against the subsequent parties, Thrall, Wheeler, or Leach, was by virtue of his mortgage upon the land, — being a pre-existing incumbrance, and to be satisfied out of it, before their title could be good and perfect. His whole claim, however, was upon the land; and whatever might operate to release the land from his lien by virtue of his mortgage would entirely destroy all Ms rights, as against all the previpus parties, except Wright. What, then, were the rights of Leach, or what would they have been, rather, if Slason had not executed the bond in question? He had no claim, or right of action, against Wheeler, or Thrall, except as connected with the land. If he were disturbed in his title or possession of that, he might then seek a remedy against them upon their covenants. He could maintain no action upon his covenants, at least for the recovery of any thing more than mere nominal damages, until he had either been evicted from the land, or had been compelled to remove the incumbrance upon it. His rights upon the covenants of Wheeler and Thrall were merely to be indemnified in the title and possession of the premises. The bond of Slason to him having effectually released the land in his possession from the mortgage, and thus placed him out of danger of any eviction under it, his claim upon the covenants of Wheeler and Thrall is also discharged, and ho has no right remaining against them, which can be enforced either by himself, or Slason.
It is undoubtedly true, that courts of chancery do often interfere, for the purpose of correcting agreements and contracts of almost every description, when the legal effect of the contract is entirely different from what the parties intended at the time it was made; and this, too, in cases, where the mistake of the parties was in relation to the effect merely, and so might be said to be rather a mistake in relation to the law, than of fact. Such was the case of *268Mower et al. v. Hutchinson, 9 Vt. 242, cited by the orators. But we apprehend, that the courts of chancery have never interfered to correct or restrain the effect of contracts between parties upon this ground, except in cases, where the contract might still operate in the manner and to the extent the parties intended, when they made it, and its farther and different operation, which was not contemplated by them, be restrained. In the case of Mower et al. v. Hutchinson the parties intended their quit claim deeds to have the operation merely to divide a farm, which they before owned jointly; but the effect of Mower’s deed was to cut off a right, which he had, to flow a portion of the same farm. The court restrained the operation of the deed, beyond what the parties intended by it; but the effect intended by the parties remained.
In the present case Slason intended to release his lien, by virtue of his mortgage, to Leach, and did so. Leach acted upon it and purchased the farm, which otherwise he would not have done. The legal effect of this release to Leach was, to discharge all claim upon the land, and upon the covenants of Wheeler and Thrall to Leach, —as their liability depended entirely upon the mortgage remaining as a subsisting lien upon the land, and thus enforced against Leach.
The orators do not claim, that there is any ground for setting aside the bond, as against Leach, because it has the very effect, as to him, which Slason intended. Unless it is set aside as to Leach, the orators can have no relief against the other defendants, — as his claim against them must be through Leach alone, who is discharged; so that in this case the different operation of the contract, beyond what was intended, is merely a legal effect, or result, of what they did intend; and the court cannot interfere to relieve the party, except by annulling the very contract understandingly and intentionally entered into by the one party and received and acted upon by the other.- It is believed, that no case can be found, where the court of chancery have ever gone to that extent; and we do not see, that there was any sufficient ground to justify such a call upon the chancellor in the present case.
The decree of the chancellor is affirmed, with additional costs, and remanded to the court of chancery to be carried into effect.
