delivered the opinion of the Court.
We do not find it necessary to determine the question whether Olds was a bona fide purchaser of this mortgage or not. In a case submitted subsequent to this one, we have been called upon to examine the question as to how far the rights of the assignee of a mortgage, purchased for a valuable consideration, before due, and in ignorance of any equities or defense, .shall be affected by such defense; and, as this record also presents the question, and as the ‘conclusion at which we have arrived, decides the case, we shall here consider this question and none other.
By the common law, choses in action were not assignable. Por the convenience of commerce, by the statute of Anne, in England, certain choses in action were made assignable, so as to vest in the assignee the legal title, as promissory notes and bills of exchange. We have a statute, also, making certain choses in action assignable, prescribing a particular mode in which they shall be assigned.^ Our statute provides, that any promissory note, bond, bill, or other instrument in writing, whereby one person promises to pay to another any sum of money, or article of personal property, or sum of money in personal property, shall be assignable by indorsement thereon. Now, the mortgage to foreclose which this bill was filed, was given to secure the payment of two promissory notes which were assigned by the payee and mortgagee to the complainants. This was, in equity, an assignment of the mortgage. The notes were assignable by the statute, but the mortgage is not, nor is it assignable by the common law. The assignee of a mortgage has no remedy upon it by law, except it be treated as an absolute conveyance, and the mortgagee convey the premises to the assignee by deed; and upon the question whether this can be done, the authorities are conflicting. Even our statute, authorizing forclosures of mortgages by scire facias, has carefully confined the right to the mortgagee, and does not authorize this to be done by assignees. But it is said that the assignment of the notes carries with it the mortgage, which is but an incident to the principal debt. That is true, in equity, and only in equity. Courts._ of equity will not be confined to legal forms and legal titles, but look beyond these, to the substantial, equitable rights of parties, and allow parties who have equitable rights, to enforce those rights in their own names, without regard to legal titles. The assignee of a judgment, even, may, in his own name, enforce it in equity. But while courts of equity thus enforce equitable rights, they do it with a scrupulous regard to the equitable rights of others. Thus, if the assignee-of a judgment attempt to enforce it in equity, no1 matter how much he paid for it, or how ignorant he might, have been that it had been paid, or that there was other j reason why it should not be collected, the court of equity will! look into all the circumstances, and will not enforce it in hisf favor, if it ought not to be enforced in the hands of the| assignor. He who buys that which is not assignable at law, relying upon a court of chancery to protect and enforce his rights, takes it subject to all infirmities to which it is liable in the bands of the assignor ; and the reason is, that equity will not lend itself to deprive a party of a right which the law has secured him, if such right is intrinsically just of itself. ’ -
, We have not met with a single case, where remedy has been sought in a court of chancery, upon a mortgage, by-an assignee, in which every defense has not been allowed which the mortgagor or his representatives could have made against the mortgagee himself, unless there has been an express statute, authorizing the assignment of the mortgage itself."' There are many cases in which the assignees have been prop tected against latent equities of third persons, whose rights, or even names, do not appear on the face of the mortgage. And the reason is, that it is the duty of the purchaser of a mortgage to inquire of the mortgagor if there be any reason why it should not be paid ; but he should not be required to inquire of the whole world, to see if some one has not a latent equity which might be interfered with by his purchase of the mortgage, as, for instance, a cestui que trust. /
We shall refer to a few of the many cases to be met with on this subject. In Murry v. Sylburn, 2 J. C. R. 441, the question arose upon a bill to foreclose a mortgage by the assignee, and Chancellor Kent said: “ It is a general and well-settled principle, that the assignee of a chose in action takes it subject to the same equities it was subject to in the hands of the assignor. But this rule is generally understood to mean, the equity residing in the original obligor, and not an equity residing in some third person, against the assignor.” And for this distinction he assigns the reason above stated. Again, he says, in the same case: “ But bonds and mortgages are not the subjects of ordinary commerce.” Here is expressed the very essence of the reason of the law. 1 Mortgages are not commercial paper. It is not convenient to pass them, from hand to hand, performing the real office of money in commercial transactions, as notes, bills and the like._When ,one takes an obligation secured by a mortgage, relying upon the mortgage as the security, he must do it deliberately, and take time to inquire if any reason exists why it should not be enforced ; while he may take the mere promise to pay the money as commercial paper, and depend upon tbe personal security of tbe parties to it. It may be said to be a distinguishing characteristic of commercial paper, that it relies upon personal security, and is based upon personal credit. It is apart of the credit system, which is said to be the life of commerce, which requires commercial instruments to pass rapidly from hand to hand. Mortgage securities are too cumbersome to answer these ends. The note itself, though secured by a mortgage, is still commercial paper; and when the remedy is sought upon that, all the rights incident to commercial paper will be enforced in the courts of law. But when the remedy is sought through the medium of the mortgage ; when that is the foundation of the suit, and the note is merely used as an incident, to ascertain the amount due on the mortgage, then the courts of equity, to which resort is had, must pause, and look deeper into the transaction, and see if there be any eqnitable reason why it should not be enforced. He who holds a note, and also a mortgage, holds in fact two instruments for the security of the debt; ñrst, the note with its personal security, which is commercial paper, and, as such, may be enforced in the courts of law, with all the rights incident to such paper; and the other, the mortgage, with security on land, which may be enforced in the courts of equity, and is subject to the equities existing between the parties. The right of an assignee to set at defiance a defense which could be made against the assignor, is an arbitrary statutory right, created for the convenience of commerce alone, and must rely upon the statute for its support; and is not fostered and encouraged by courts of equity.
In Westfall v. Jones, 23 Barb. 10, the court said : “ Does the plaintiff, being a bona fide purchaser and assignee of the bond and mortgage, stand in any better condition than the person from whom he derived his title ? It is a well-settled principle, that the assignee of a chose in action, takes it subject to ¿11 the equities which existed against it in the hands of the assignor.” In this case, the defense to the foreclosure was, that the mortgage was given without consideration, and to defraud creditors, and the court refused to enforce it, but left the assignee, as it would have left the mortgagee, where their contract left them. The case thus decides that the term equities, as here used, means defenses. The opinion of the court proceeds : “ But I am prepared to hold that the plaintiff has no other or greater rights in relation to this bond and mortgage, and stands in no better position, than Parsons, the mortgagee.”
So, in Pennsylvania the same rule was held. In Mott v. Clark, 9 State R. 399, the court said: “ He (the assignee) takes it (the mortgage) subject to all the equities of the mortgagor, but not to the latent equities of a third person; ” holding the same rule precisely as the case first referred to, as decided by Chancellor Kent; and such also was the case of Prior v. Wood, 31 Pa. State R., where the court protected the assignee of the mortgagee against the latent equities of third persons against the assignor. And this is as far as any court has gone in the protection of a iona fide assignee of a mortgage, when the proceeding was on the mortgage itself, and in the absence of any express statutory provision authorizing the assignment of the mortgage.
1 We find the law to be, both upon principle and authority, that the assignee of the mortgage in this case, took it subject to the defense which the mortgagor had against it in the hands of the assignor. Of the sufficiency of that defense, to the extent admitted by the Circuit Court, no question was made.
The decree mus*t be affirmed.
