It is established as a principle by our decisions, that, where the creditor of the insolvent estate of a deceased person holds a mortgage or other collateral security for his debt, which he received from his debtor, he cannot be admitted to prove his debt except for the balance which may remain afterdeducting the value of the security, (which value is first to be ascertained by sale or appraisal,) unless he will surrender the security to go into the common fund for the payment of creditors. Amory v. Francis, 16 Mass. 308. Middlesex Bank v. Minot, 4 Met. 325. Savage v. Winchester, 15 Gray, 453. Haverhill Loan & Fund Association v. Cronin, 4 Allen, 141. But as this rule does not apply where the collateral security is furnished by a third person not primarily responsible for the debt, because, if the security is first applied to the reduction of the debt, there is eo instanti created a new debt of equal amount in favor of the surety whose property is thus expended, the plaintiff deems that it has here no proper application. Savage v. Winchester, ubi supra. The security in question was certainly furnished by the debtor, but the contention of the plaintiff is, that, as it here appears that Seekell, previously to conveying in mortgage to the plaintiff, had made a quitclaim deed of the premises to Mrs. Foster, reserving to himself and wife a life estate therein, although the record title was still in him, he had no right thus to furnish security to the plaintiff, and it must be *414dealt with as if it had been furnished by Foster. The deed which Foster received from Seekell contained a warranty only against incumbrances suffered by him. There was on the estate at that time a mortgage to the plaintiff made by Seekell’s grantor, one Presbrey, which Seekell had agreed with Presbrey to pay, but he made no agreement with his grantee to pay this mortgage, nor did he warrant her against it. The mortgage made by Seekell to the plaintiff was for the same amount as the Presbrey mortgage, and, on the day it was made, the Presbrey mortgage was discharged. The promissory note, the amount of which is here sought to be recovered, was given at the same time, and was for the same amount. It does not appear that any money passed in the transaction.
A proceeding to which Foster is not a party does not afford the means of determining whether, as between her and Seekell, the latter had a right to make this mortgage and furnish this security, nor whether the application to the reduction of this debt would or would not immediately create a new debt equal in amount thereto from the estate of Seekell to her. As the security was not furnished to the plaintiff by Foster, it has made no contract with her and is under no obligation to her, and it should avail itself of the security received from Seekell toward the satisfaction of its debt, or, by a proper assignment and transfer of it to the administrator of the estate of Seekell, enable him to assert, as against Foster, the right of Seekell to do that which he did. It is only in this mode that, as between the other creditors, of Seekell and Foster, it can be determined whether he had such a right.
The result to which we have arrived does not conflict with the decision in Wilson v. Bryant, 134 Mass. 291. In that case, the owner of a parcel of land had mortgaged it, subsequently conveyed his equity of redemption, and, several years after, went into insolvency. The mortgagee sold the land under a power of sale contained in his mortgage, without obtaining any order of the insolvency court, and applied the proceeds in part satisfaction of his debt. It was held that he was entitled to prove the balance of his claim against the estate of the insolvent; and that the Gen Sts. c. 118, § 27, did not apply. That case rests upon the ground that the provisions of the Gen. Sts. c. 118, § 27, *415could not have been complied with. The equity of redemption was held by a stranger, not subject to the jurisdiction of the court, and, as the statute requires that “ the property ” should be sold, this could not be done, as it might were the equity held by the assignee. While also the statute requires that the “creditor and assignee respectively” shall execute all papers necessary for effecting a conveyance, it assumes that they will be sufficient for that purpose. In the case then under consideration, such would not be their effect, and it was deemed that the statute did not contemplate an assignment of the mortgage to be kept up as independent security, while the creditor was permitted to prove his debt secured thereby. As the conditions of the insolvency act could not be complied with, it was therefore held that the statute did not include the case of the petitioner, and he was permitted to prove the balance of his claim.
The case at bar does not present a question arising under the insolvent law of the Commonwealth, nor on the rights or duties of creditors, necessarily to be determined by its statutory provisions, or defined by the limitations directly or inferentially to be found therein. Before the enactment of our present system of insolvent laws, it was decided that the right of a creditor, who had received security from a deceased person to prove his debt before the commissioners on his insolvent estate, must be determined by ascertaining that which was just and equitable between him and the other creditors, who, like him, were entitled to look to the general assets, but who could not directly avail themselves of the funds or property which he had received as security for his debt; and further, that the provision that the estate should be divided pro rata required that the creditor having security should receive no advantage beyond the actual value of the property secured. Amory v. Francis, ubi supra. It has also been held since, that the creditor might in such case prove his whole debt, if he would surrender the security held by him to go into the common fund for the benefit of creditors. Savage v. Winchester, ubi supra.
The plaintiff in the case at bar will neither avail itself of the mortgage security which it has, by applying it to the payment of its debt, nor will it surrender or transfer the same to the assignee. It cannot be equitable or just that a creditor, having *416a mortgage from the debtor, can so use it as to obtain thereby greater security than it was intended to give him. When such mortgage was made to the creditor, it was security only for a proportion of the debt equal to the value of the property. For all the rest of the debt the creditor relied on the personal credit of the debtor, as he would have relied if no security had been taken. But if the creditor may prove the whole debt, and hold the mortgage for the balance, it becomes security for as much more than the value of the property as is the amount of the dividend which may be received on the whole debt. Amory v. Francis, ubi supra.
Even if the assignee is not the owner of the equity, the difficulty which is found of giving an effectual title when such is the case, and when an estate must be disposed of according to a statute which gives authority to sell “the property” only, need not here occasion embarrassment. When seeking to divide the insolvent estate ratably, and according to equitable principles, and not strictly limited to methods prescribed by a statute, there appears to be no reason why the creditor should not be required to sell the mortgage, or have it fairly appraised, if he prefers to retain it, or why, if he desires to prove for his whole debt, he should not transfer it to the assignee representing the creditors. There can be no difficulty in holding that, when the mortgage is thus sold or transferred, the purchaser or transferee is subrogated to the rights which the mortgagee might have exercised under it; and that the debt which it was intended to secure may be treated as still existing, so far as is necessary to enforce the rights which the mortgagor conveyed by it. The question presented by the case at bar is strictly one between the plaintiff as a secured creditor and the administrator representing the remaining creditors, and concerns only their rights respectively. If it shall be sought hereafter to enforce the mortgage, there will then be an appropriate time to consider what are the rights of Mrs. Foster, as the owner of the equity of redemption.
In considering what should be the true rule to be adopted in the ratable division of the estates of persons deceased insolvent, while valuable analogies may be obtained from the bankrupt or insolvent laws, they are analogies only. It is worthy of notice, *417in determining what, independently of the statute, is just and equitable, that, while, as held in Wilson v. Bryant, ubi supra, the insolvency act of this Commonwealth does not provide for any transfer or sale of mortgage security on property, but only for a sale of “ the property ” itself, the United States bankruptcy act in terms provided that “ the creditor may release or convey his claim to the assignee upon such property,” (such as had been mortgaged or pledged,) “ and be admitted to prove his whole debt.” Unless the security is thus released or conveyed, or its value ascertained by sale or agreement, and deducted from the debt, the creditor was not permitted to prove for any part thereof. U. S. Rev. Sts. § 5075.
A majority of the court are therefore of opinion that the plaintiff had no right to prove for the full amount of the promissory note while it still held the mortgage security; and the decision of the commissioners is Affirmed.
