FIRST NATIONAL BANK OF MEXICO, a Banking Corporation, Plaintiff-Respondent,
v.
Margaret E. MUNNS et al., Defendants-Appellants.
No. 41430.
Missouri Court of Appeals, Eastern District, Division Four.
July 29, 1980.
*911 Thomas J. Osborne, Mexico, for defendants-appellants.
Steven W. Vanmatre, Mexico, for plaintiff-respondent.
SIMON, Judge.
Appellants appeal from a summary judgment ordering the delivery to respondent of funds held in a trust savings account assigned as security for a promissory note payable to respondent. We affirm.
Robert L. Munns borrowed $15,000 from the First National Bank of Mexico (respondent) and executed a promissory note in the same amount. He assigned a trust certificate of deposit in the amount of $15,104.86 as security for the note. Later, Robert L. Munns borrowed an additional $7,000 from the respondent and executed a promissory note in the same amount. He defaulted in the payment of the notes and the respondent (First National Bank of Mexico) brought this action for recovery on the promissory notes made by Robert L. Munns and to order the delivery by Citizens Savings Association, of funds in their possession as evidenced by a trust certificate of deposit pledged, under the conditional assignment, as security for the $15,000.00 note. Robert L. Munns failed to answer and defaulted, and appellants Margaret E. Munns and Margaret Ann Rouse (Robert L. Munns' mother and sister) intervened as defendants pursuant to Rule 52.12(a), claiming an interest in the trust savings account evidenced by the certificate. Appellants filed an answer and counterclaim to respondent's petition and crossclaim against Robert *912 L. Munns and Citizens Savings Association. Respondent and appellants filed cross motions, supported by exhibits and affidavits, for summary judgment as to the ownership of the funds in the trust savings account.
Appellants were named beneficiaries of a trust savings account established by Robert L. Munns depositing $15,104.86 into a savings account designating "Robert L. Munns, trustee for Margaret E. Munns and Margaret Ann Rouse, Beneficiaries." Robert L. Munns, without the knowledge, consent or authority of the appellant, Margaret E. Munns, had withdrawn the $15,104.86 from a joint savings account at Citizens Savings Association, designated "Margaret E. Munns and Margaret Ann Rouse and Robert L. Munns, joint tenants with right of survivorship and not as tenants in common." Appellant Margaret E. Munns had created a joint savings account with the funds she had received from the sale of her home following the death of her husband. It was her intention to retain the right to use the money during her life but upon her death, it was to be divided equally between the surviving joint tenants. Each of the joint tenants executed the deposit agreement establishing the joint account. Said agreement authorized withdrawal from the account or the pledging of account by any of the joint tenants. Only Robert L. Munns executed, as grantor, the Discretionary Revocable Trust Agreement establishing the trust savings account.[1] At the time of the pledging and assignment of the trust certificate, Robert L. Munns assured respondent's vice-president that the funds evidenced by the trust certificate belonged to him and that he had the authority to pledge them or to withdraw them at any time, and that he would do so in the event of a default on the promissory note. The respondent gave written notice of the assignment to Citizens Savings Association. The trial court entered a default judgment in favor of respondent against Robert L. Munns on the notes and in favor of appellants against Robert L. Munns for the money withdrawn from the joint savings account. The trial court sustained respondent's motion for summary judgment and ordered delivery of the funds held in the trust savings account to the respondent. Appellants appeal from the trial court's entry of summary judgment for respondent and the denial of their motion for summary judgment.
Appellants contend the trial court erred in finding the assignment of the trust certificate valid and entering summary judgment for the reasons that: (1) the delivery of the joint certificate created a bailment and Robert L. Munns as a bailee had no authority to assign it; (2) no "Totten" trust was created since Robert L. Munns did not deposit his own property into the account; (3) the respondent had a duty to inquire of the trust beneficiaries concerning the assignment of the trust certificate; (4) Robert L. Munns' pledging and assignment of the trust certificate did not constitute an effective revocation of the trust; and (5) the pledging of the trust property was a breach of trust and the respondent took the assignment subject to the rights of the beneficiaries.
*913 A summary judgment shall be entered where the pleadings, depositions and admissions on file, together with the affidavits, if any, show there is no genuine issue as to any material fact and that the party is entitled to a judgment as a matter of law. Rule 74.04(c).
On appeal, appellants allege that the trial court erred as a matter of law and do not raise any issue as to any material fact and our review did not disclose any.
Appellants initially contend that the delivery by appellant Margaret E. Munns of the certificate of deposit, evidencing the joint savings account, to Robert L. Munns was a bailment and that he had no power to assign it for his own benefit. Our review of the record fails to disclose any evidence of a bailment or that this theory was advocated by the appellants in the proceedings before the trial court. We shall not conduct our review on a theory different from that on which the case was tried. Teson v. Vasquez, 561 S.W.2d 119, 132 (Mo.App. 1977). Appellants' first point is not well taken.
Appellants next contend that the trial court erred in finding that a valid "Totten" trust was created since Robert L. Munns did not deposit his own funds into the trust account, and as a result, the assignment was invalid. The New York Court of Appeals established the "Totten" trust principle, in In re Totten, 179 N.Y. 112, 71 N.E. 748, 752 (1904), when it held:
"A deposit by one person of his own money in his own name as trustee for another, standing alone, does not establish an irrevocable trust during the lifetime of the depositor. It is a tentative trust merely, revocable at will, until the depositor dies or completes the gift in his lifetime by some unequivocal act or declaration, such as delivery of the passbook or notice to the beneficiary. In case the depositor dies before the beneficiary without revocation, or some decisive act or declaration of disaffirmance, the presumption arises that an absolute trust was created as to the balance on hand at the death of the depositor."
The tentative trust, sometimes described as a "Totten" trust, has been recognized in Missouri. See § 369.154 and § 369.179, (Savings and Loan Association);[2] § 362.475 and § 362.480 (Banks and Trust Companies); Frank v. Heimann, 302 Mo. 334, 258 S.W. 1000, (banc 1924).
Appellants claim that since Robert L. Munns did not use his own funds to create the trust account, a "Totten" trust did not come into being and rely on In re Estate of Dillon, 441 Pa. 206, 272 A.2d 161 (1971) to support their point. Dillon concerned the depositing by a testamentary trustee of funds in his name in trust for the beneficiary and then placing the account for his personal obligation. The Dillon case reiterates the principle that a grantor must use his own property to create a Totten trust. We are not in disagreement with the Dillon holding. However, under the authority of § 369.154 and § 369.174,[3] and In *914 re Estate of LaGarce, 487 S.W.2d 493 (Mo. banc 1972), Robert L. Munns did place his own funds in the trust savings account. Our Supreme Court in LaGarce, id. 500, held:
"Section 369.150[4] specifically and unqualifiedly provides that if the certificate is issued in the statutory form the account `shall become the property of such persons as joint tenants and shall be held for the exclusive use of the persons so named and may be paid to any person named therein, or the survivor.' There is nothing in the statute which would warrant the conclusion that a rebuttable presumption is created that the deposit shall become the property of such persons as joint tenants and that it may be shown by competent evidence that it was not a joint tenancy even though the statutory form had been complied with. The statute says it `shall become the property of such persons as joint tenants.' The limitations were placed upon the statute by judicial interpretation apparently resulting from a consideration of common-law principles.
It is our view that the statute creates what might be described as a statutory joint tenancy which should be given effect without consideration of the strict common-law requirements mentioned in the case." (Emphasis in original)
Appellant Margaret E. Munns deposited the funds from the sale of her home in the joint savings account with her son Robert L. Munns and her daughter, appellant Margaret Ann Rouse, and they executed the joint account deposit agreement; Robert L. Munns became a present joint owner of those funds under the holding of LaGarce, supra, and could legally withdraw the funds. Therefore, the depositing of those funds in the trust savings account and the execution of the discretionary revocable trust agreement created a valid Totten or tentative trust, supra, § 369.179. Appellants' second point is without merit.
Appellants next contend that the trial court erred in finding the assignment of the trust certificate valid in that the respondent had a duty to inquire of the trust beneficiaries as to the authority of the trustee and in failing to do so, took the assignment subject to the rights of the beneficiaries. Appellants rely on § 400.3-304 for the proposition that respondent had knowledge of a fiduciary negotiating an instrument (Trust Certificate of Deposit) for his own benefit in breach of his duty and therefore took subject to the rights of the beneficiaries.
Appellants' reliance is misplaced. Section 400.3-304 pertains to negotiable instruments and not the trust certificate of deposit involved herein. This trust certificate of deposit is not a negotiable instrument; it is not payable to order or to bearer. Kaw Valley State Bank & Trust v. Commercial Bank of Liberty, 567 S.W.2d 710, 712 (Mo. App.1978).
*915 Appellants argue other points of law concerning a creditor's actual or constructive notice of a breach of trust but ignore § 369.154(2) which specifically authorizes the pledging of a savings account and requires notice to the association where the account is maintained. There is no statutory requirement of notice to the beneficiaries (appellants) under the facts of the case herein. The respondent made inquiry of Robert L. Munns' authority in regards to the funds and notified the Citizens Savings Association of the pledge. Appellants' point is without merit.
Appellants next contend the trial court erred in finding that the assignment of the trust certificate constituted a revocation of the trust, and that the respondent took the funds free of the rights of the trust beneficiaries. Appellants argue that the trust could be revoked only by an actual withdrawal of the funds or by written notice of revocation by the trustee (grantor herein) of the trust.
Section 369.179[5] grants the member,[6] while living, the right to withdraw the funds from the account, in whole or part, and that such withdrawal shall be a valid and sufficient release of the savings and loan association to the extent of the withdrawal. Section 369.154(2) provides that the owner of a savings account may pledge his account to secure his own obligation and, if written notice of such pledge is served upon the savings and loan association, the pledgee shall be protected. In the present case, Robert L. Munns was the owner of the trust account and the respondent was the pledgee.
Under the mandate of the statutes and the discretionary revocable trust agreement, a withdrawal of the funds would constitute a revocation of the trust to the extent of the withdrawal. The crucial question is "Did the pledging and assignment of the trust account as security for the note result in a revocation of the trust to the extent of the amount necessary to satisfy the balance due on the note?" We hold in the affirmative.
The holding set forth In re Totten, supra, at 752, proscribed that the trust could be revoked by some decisive act or declaration of disaffirmance, and the Restatement[7] provides that a tentative trust of a savings deposit can be revoked by the depositor at any time during his lifetime, by a manifestation of his intent to revoke the *916 trust. No particular formalities are necessary to manifest such an intention. Although the tentative or Totten trust role allows revocation by a decisive act or declaration of disaffirmance, most courts do not consider an oral declaration, absent positive conduct manifesting an intention to revoke, as effectively revoking a tentative (Totten) trust. See 46 A.L.R.3d 487, 500, § 5. The facts establish that Robert L. Munns assured the respondent's vice president that he had the right and power to pledge and withdraw the funds and would withdraw in the event of his default on the promissory note. He pledged the certificate and executed an assignment. The statements and actions were decisive and constituted a revocation of the trust to the extent necessary to secure the promissory note. See Klaw v. Kramer, 56 Misc.2d 173, 288 N.Y.S. 322, 323 (1968); Evinger v. MacDougall, 28 Cal.App. 2d 175, 82 P.2d 194 (1938).
Our research has revealed no Missouri case on the point under consideration, and § 369.179 is silent as to methods of revocation, except by redemption or withdrawal. However, § 369.154(2) specifically authorizes the pledging of a savings account by its owner and, upon written notice to the association, the pledgee shall be protected. It was obviously the legislature's intent to allow trust savings accounts, established in accordance with the statutes, to be revoked in such a situation. To hold otherwise, would result in a frustration of the legislative mandate.
In addition, the discretionary revocable trust agreement specifically provides for revocation by the trustee, if he is the grantor. He could revoke by withdrawal in part or in full but no other revocation would be valid unless written notice is given to the association. Written notice, in accordance with § 369.154(2), was given to the association. Appellants argue that the written notice should have been given by Robert L. Munns himself but neither the statute nor the trust agreement so demands. We rule this point against the appellants.
Appellants' last allegation of error, is a summarized restatement of their previous contentions. We find no new allegations of error raised therein. Our holding in appellants' other contentions are dispositive of this allegation.
Judgment affirmed.
SMITH, P. J., and SATZ, J., concur.
