¶1The defendants took their mortgage expressly subject to the prior mortgage. It may be admitted *437that the mortgagor could defeat the prior mortgage, quoad the Herkimer County Bank as invalid. (2 R. S. 519, § 7, 5th ed.) But the question is a different one when the defendants propose to intervene between the mortgagor and the bank. It cannot be distinguished in principle from the case of a usurious mortgage which the statute declares to be void, but which a purchaser of the land, who takes it subject to the usurious mortgage, cannot avoid for that reason. (Post v. Dart, 8 Paige, 639. Cole v. Savage, 10 id. 583.) It can be avoided only by the party who made it, or by some one standing in legal privity with him, and not by a mere stranger to the transaction. (Dix v. Van Wyck, 2 Hill, 522) A purchaser of the equity of redemption cannot, nor can a subsequent mortgagee, set up the defense. (Sands v. Church, 2 Seld. 347.) The defendants having taken their mortgage subject to the prior mortgage, now come into court and claim to violate their own agreement by setting up a defense, in which the debtor alone has an interest. In this I think they are mere volunteers, and equity in general is remedial only to those who come in upon actual consideration. (1 Fonbl. Eq. 348.) In a bill for relief, the want of title in the plaintiff is fatal. (Story’s Eq. Pl. § 512.) And when the defendants have precluded themselves from questioning the plaintiff’s title, but have agreed to take subject to it, there is no ground upon which they can invoke the aid of a court of equity to put them in a better position than they contracted for. If they succeed, they take a lien larger than they contracted for, and leave the debtor still liable to pay the debt which they agreed should be a prior charge upon the mortgaged premises. I think the judgment should be affirmed.

¶4No exception was taken by the defendants to the ruling in respect to the debts due the banking association, and that as to these debts, the plaintiff’s *438mortgage was valid; and it was not claimed upon the argument of this appeal that these associations were affected by the provisions of § 7, art. 1, tit. 2, ch. 18 of part 1st of the revised statutes. (2 R, S. 5th ed. 519, § 7.) That section declares that no conveyance, assignment or transfer of any effects for the use, benefit or security of any such corporation (moneyed corporation) shall be valid in law, unless it be made .to the corporation directly and by name. The same clause which exempts certain assignments - for the benefit of creditors from the operation of the section, need not be quoted, as the plaintiff’s mortgage is not within the class of exempted conveyances. The Herkimer County Bank was a moneyed corporation, and directly within the prohibition of the statute; and the mortgage, so far as it was intended as a security for its debt, was not valid in law. The debt remains, but the security is void, and cannot be enforced. The statute not only prohibits the security for the benefit of a moneyed corporation in this form, but in terms declares, all such securities to be void. But the court, at special term, sustained the mortgage and gave the Herkimer County Bank the benefit of it as a security for its debt, or rather gave effect to it as a security for the debt upon the strength of the clause in the junior mortgage to Hyde & Everitt, .declaring that the lands were subject to the mortgage in suit, the judge holding that Hyde & Everitt, the junior mortgagees, were not in a condition to question its validity. That mortgagees as well as grantees are in privity with their mortgagor, and may avail themselves of any defect in an adverse claim or title which would have been open to their mortgagor, I do not understand to be questioned. A mortgagee is a grantee upon condition, and grantees as well as heirs, devisees and personal representatives, may set up any defense, as for example that of usury, against a mortgage or other lien upon lands, given or created by their grantor or ancestor. Claiming under the mortgagor, Pitt, and in privity with .him, the defendants, Hyde & Everitt, may avail themselves of any defect in the *439plaintiff’s mortgage which goes to and affects its validity, unless precluded by some technical estoppel or. special circumstance which takes their case out of the ordinary rule, and deprives them of the rights ordinarily incident to their condition as grantees. (Ord on Usury, 131. Blydenburgh on Usury, 106. Post v. Dart, 8 Paige, 639. Shufelt v. Shufelt, 9 id. 137. Dix v. Van Wyck, 2 Hill, 522. Morris v. Floyd, 5 Barb. 130.) Questions analogous to that made here have frequently arisen in respect to mortgages alleged to be usurious, and so far as there is an analogy between defenses for usury and the defense here Interposed, the cases referred to may be regarded as authority, and it was upon the authority of that class of cases that the decision at the special term rested. It is well settled that the debtor or borrower may waive the defense of usury, and so charge his property, or even a third person, with the payment of a usurious debt, that his grantee or such third person will be precluded from alleging the usury. A grantee who takes by grant the mere equity of redemption, that is, that part of the estate or interest not covered by. the mortgage, will not be permitted to defend against the mortgage upon that ground. So too, the grantee of mortgaged premises who assumes the payment of the mortgage debt, or who takes the premises expressly charged with its payment, is estopped from alleging usury "as a defense. The debtor has a right to set apart his property to the payment of a debt, although it be usurious, and the trustee or one who upon a good consideration moving from the debtor to him, has undertaken to pay it, is estopped from alleging that the debt is usurious.
