delivered the opinion of the Court.
This case is here on appeal from a decree rendered by the chancery court of Davidson county. Appellants here were, respectively, complainant and cross complainant below. The bill was filed March 12,1909.
There is no material controversy about the facts. There are two assignments of error, by each of which appellants insist that the court below did not correctly apply the law to the facts. It appears that Len K. Hart died intestate in Davidson county, on February 14,1909, leaving surviving him his widow, Mrs. Lucy E. Hart, and two minor children. The Nashville Trust Company, appellant, is the guardian of these children, and the widow is the administratrix of the estate of said decedent.
The original bill was filed by said guardian, and the widow as such administratrix, and as widow of said decedent, was joined with appellee bank as a defendant to the bill.
*621She answered the hill in both capacities, and her individual answer was made her cross bill. The original bill sought a decree against the appellee, the First National Bank, for the sum of $4,000, alleged to be two-thirds of the proceeds of a policy of insurance on the life of said decedent, which had been collected by said appellee.
The cross bill of the widow sought a decree against said defendant for the remaining one-third of said policy of insurance, or the sum of $2,000.
The appellee bank, defendant below, admitted the collection by it of said $6,000 life insurance policy, but set up by way of defense that the policy was by its terms payable to the executors, administrators, or assigns of the decedent, and that he had, Avhile in life, made an assignment of said policy to defendant bank, absolute in terms, but, in fact, to secure the payment of a particular debt; and that after the payment of said particular debt, for the space of some seven years or more, and down to-the date of his death, said decedent had permitted said policy to remain in the hands of appellee bank as a general collateral, under said original assignment, to secure-all amounts said decedent might owe it from time to time,, howsoever such indebtedness might arise between them,, whether by note, draft, or otherwise; and that therefore said widow and tAVO children of decedent were entitled' to recover from it only such of the proceeds of said policy as might remain after the indebtedness held by it, and chargeable against said, proceeds, had been deducted by.' it from the gross amount of $6,000.
*622Upon the issues thus made, proof was taken, and final decree was rendered on Jnne 14, 1910, wholly in accord with the contention of appellee bank. It was decreed to be entitled to hold the amount of its indebtedness covering the full sum of the policy, less the sum of $1,765.37, which, it was decreed, should be paid by it, as follows : One-third to Mrs. Lucy E. Hart, widow, and two-thirds to the Nashville Trust Company, guardian of said minors.
Prom this decree, the Nashville Trust Company, guardian, and the widow, in her individual right and as ad-ministratrix, duly appealed.
The assignments of error are as follows:
First. That the chancellor erred in decreeing that appellee was entitled to have its debt paid out of the proceeds of the policy,
Second. That the chancellor erred in holding that the evidence of Watts., the president of appellee bank, was competent.
We remark in passing that neither of these assignments of error raises any question as to the correctness of the decree in the determination of the amount of the debt of the appellee bank, which was, as' it claimed, chargeable against the policy, so that we must assume, from the failure to assign error on this point, that in this respect there was no error in the decree, and that the pith and substance of the assignments of error is that, in whatever amount the decedent may have been indebted-to the appellee, no part of the sum was properly chargeable against the policy, and that the chancellor *623received incompetent evidence in arriving at tlie contrary conclusion.
Relative to tlie first assignment of error, it will be noted that by our Acts 1845-46, c. 216, section 3, carried as section 4030 of Shannon’s Code, it is provided that a life insurance effected by a husband on his own life shall inure to the benefit of the widow and nest of kin, to be distributed as personal property free from the claims of his creditors. But it is a mistake to suppose that by reason of this statute the husband is without power to control the matter of who shall benefit by an insurance on his life, where the policy is payable to his executors, administrators, or assigns. The precise question came before this court in the case of Rison v. Wilkerson & Co., 3 Sneed, 566, where the insurance policy was not by its terms made payable to the’widow’ and children and was by the husband during his lifetime assigned to a creditor as collateral security for a debt, and it was decided that the creditor was entitled to hold the proceeds to the extent of the debt, and, further, to the extent of the amount of advances made by the creditor after the assignment for the payment of premiums oh the policy.
The principle was also applied where the disposition of the policy by the husband in his lifetime was by will, where the policy was payable to his executors, adminisr trators, or assigns, and it was held that the claim of the legatee, under the will, was superior to that of his widow and children, who relied on the statute. Williams v. Carson et al., 9 Baxt., 516.
*624The principle was again applied, in Catholic Knights v. Kuhn, 91 Tenn., 214, 18 S. W., 385, and other cases not necessary to mention. In fact this doctrine may be said to be settled beyond dispute or cavil by our authorities, and to be based on the idea that when the policy is payable to the executors, administrators, or assigns of the husband, it is his property and subject to his disposition. Where, hoAvever, the policy is, by its terms, made payable on the death of the husband to the widow and heirs, or to his legal heirs, it is equally well settled that they take a vested interest, and the poAver of the husband to defeat their interest by subsequent assignment is lost. See Gosling v. Caldwell, 1 Lea, 455, 27 Am. Rep., 774, and authorities there cited.
It is also well settled that if the policy, by its terms, be payable to the legal representatives of the assured husband, and he die Avithout having made any disposition of it, that by the operation of the statute the claims of his widow and next of kin, whether the latter be children or other kin falling within the terms of the statute, Avill prevail over the claims of his general creditors in a contest over the proceeds of the policy, whether the estate of the insured be solvent or insolvent, and although in the particular case the policy may have been issued before" the assured was married. See Rose v. Worthham, 95 Tenn., 507, 32 S. W., 458, 30 L. R. A., 609, citing Harvey, Adm’r. v. Harrison, 89 Tenn., 476, 14 S. W., 1083; Collier v. Latimer, 8 Baxt., 420, 35 Am. Rep., 711; Jackson, Orr Co. v. Shelton, 89 Tenn., 82, 16 S. W., 142, 12 L. R. A., 514; State, use, etc., v. Anderson, 16 Lea, 338.
*625It is an uncontroverted fact of this record that the policy in the case at bar was by its terms payable to the executors, administrators, or assigns of said decedent. This being true, his power to assign it, so as to defeat the' claims of his wife and children under the statute, was absolute. It is an equally uncontroverted fact that this poAver was exercised by him. He made an assignment of the policy to appellee bank, absolute on its face, by which the full legal title to the policy passed to appellee bank. This assignment was made on September 22, 1896, and acknowledged by the assignor before a notary- public on the 23d of September, 1896.
The original bill avers that this assignment Avas made, and that it was absolute in form, and there is an undisputed, copy of it in the record, which,confirms the averment of the bill.
The answers of the widow in her individual right, and as administratrix, respectively, admit that the above averment of the bill is true.
It is not claimed by appellants’ pleadings, nor is it shown by any proof, that the appellee bank, by any act or deed, ever parted with the legal title to the policy so vested in it, until after the death of the insured, when, under claim of right, the policy was surrendered by it to the company which issued it, upon payment to the ap-pellee of the sum of $6000. Nor is it claimed by the pleadings of appellants, or shown by any proof, that the decedent ever claimed that the appellee had been divested of the legal title to said policy and the right to- collect *626the same upon his death; from the date of the absolute assignment to the date of decedent’s death, the legal title and right to collect the policy was in the appellee. Strictissimi juris, the policy was not pledged or deposited as collateral; it was, on the contrary, absolutely assigned. The distinctive characteristics of a pledge or deposit of collateral are that the property must be capable of delivery to the pledgee, and must be delivered to him actually or constructively, and under a contract, the essence of which is that the thing delivered is to be held by the pledgee as a security for some debt or engagement of the pledgeor. The pledgee does not acquire absolute title by such a contract, but only a special property in the thing pledged, with the right to possession until the object of the pledge be accomplished- If the pledgeor make default, the pledgee may a bill in equity and foreclose, or he may sell without judicial process on reasonable notice to the pledgeor to redeem the pledge. The absolute title to the thing pledged is not divested out of the pledgeor until foreclosure or a sale on proper notice by the pledgee. This is the law of pledge or deposit of property, as collateral security for a debt. See Johnson v. Smith, 11 Humph., 397, citing Story on Bailments.
The theory of appellants was that the policy was' pledged. The fact was that it was absolutely assigned, leaving no vestige of legal right to it or the proceeds of it in the decedent. So it was, from the date of the assignment, during his life and at his death. The interest he had in it from the time of the assignment, during his life *627and at his death, was an equity, pure and simple, and not a legal rigivfc. With this equitable interest as his basis of credit, he contracted the debts shown by the record. If he, during life, had sought to recover the policy, and to cancel his absolute assignment of it without paying these debts, he would have been repelled by a court of equity on the ground that he who would have equity must do equity. His wife and children can have np higher rights than he. The legal right to the policy was not in them, for we have seen that, notwithstanding the statute, written as the policy was, decedent had the right to make absolute assignment of it, and exercised it in such a way as to cut off all their legal rights. They are clothed only with his equity, and as he would have been bound, so they are bound, to do equity.
Aside- from the effect of the absolute transfer of the policy, which was in.writing, it is well settled that the act of the decedent in permitting the policy which had been so assigned to remain in the hands of appellee, and oft-repeated agreements by him that it should stand as security for any amount in which he might be from time to time indebted to appellee, would have amounted to an estoppel against him, had he, during his life, attempted to secure possession of the policy without payment to ap-pellee of the indebtedness incurred on the faith and credit of the policy as a security.
The assignment of a policy need not be in writing to be valid, but is governed by the rule applicable to ordinary simple contracts. Joyce on Insurance, vol. 8, section 2326; May on Insurance, section 395; Bacon on *628Benefit Societies and Life Ins., section 297; Pliillips on Insurance, section 880.
“An oral assignment of a life insurance policy is valid under onr law.” Box v. Lanier, 112 Tenn., 403, 79 S. W., 1042, 64 L. R. A., 458.
There is no merit in the second assignment of error. The witness Mr. F.. O. Watts, who was president of the appellee bank, was not a party to this suit, and was a competent witness. Southern Life Ins. Co. v. Booker 9 Heisk., 608, 24 Am. Rep., 344; Grange Warehouse Association v. Owen, 86 Tenn., 355, 7 S. W., 457.
It follows that the decree of the chancery court must be affirmed.
