Respondents-appellants (appellants), a group which includes the widow of the decedent,1 the Attorney-General of the State of New York, an educational institution and several named charitable organizations, separately appeal from a decree of the Surrogate’s Court, New York County (Di Falco, S.) entered April 1, 1976, which determined the validity and effect of the widow’s election to take an elective share of the decedent’s estate and also determined that an inter vivos trust created in 1958 and thereafter amended, satisfies her right of election except to the extent of $10,000.
This proceeding was instituted by the Chase Manhattan Bank, National Association (hereinafter Chase Manhattan), as executor of decedent’s estate and trustee of an inter vivos trust established by the decedent in 1958, to determine the validity of a right of election filed by the widow to take a share of the estate against the provisions of the will under which she takes nothing.
In the trust agreement dated May 27, 1958, decedent established an inter vivos trust and transferred and delivered certain personal property to the trustees for the uses and purposes set forth in the agreement. In article "Second” of the agreement, decedent as settlor reserved to himself the right to revoke or change the trust at any time without the consent of anyone or even without notice except to the corporate trustee, Chase Manhattan, "provided however, that the terms of this agreement may not be changed in such manner as (a) to reduce in any way the provision made for the lifetime of the Settlor’s wife, Katherine Rose Kane Walton, in section A of Article First of this agreement except with her consent in writing or (b) to increase the obligations of the Corporate Trustee or to alter the rates of the commissions of the Corporate Trustee without its written consent.” Chase Manhattan *439was also authorized under section B to invade the principal and to make payments, with the wife’s consent, to decedent during his lifetime for certain designated purposes. Section A of article First also provided that the trust income should be paid to the decedent for life and at his death to his widow, with a power of appointment by will vested in the widow, subject to certain limitations. In default of the exercise of such power, the principal of the trust was to be paid over to the American Red Cross.
It may be noted that at the time of the creation of the trust decedent was married to another. Decedent and the present widow were married April 12, 1961.
On May 22, 1961, the decedent amended the trust agreement without his wife’s consent so as to effect a change in the designated charitable remainder beneficiaries in the event of a default by the widow in the power of appointment.
On February 15, 1963, the decedent again amended the trust agreement, this time with the wife’s consent and significant and far-reaching changes were made. The income was still to be paid to or used for the benefit of the decedent during his lifetime, and after his death to be paid to his widow or used for her benefit during her lifetime. However, the amendment added a new section C to article First which provided that upon the decedent’s death, $100,000 was to be paid or "poured over” from the principal of the trust and become a part of decedent’s residuary estate. In addition, a sum equal to all inheritance, estate and succession taxes on decedent’s taxable estate, whether passing under the agreement or by last will, was to be paid over from the principal of the trust estate to the decedent’s executors or administrators and become part of his residuary estate. Provision was made for a trust fund A in order to qualify for the marital deduction, and for a trust fund B for the maximum charitable deduction. These deductions, to some extent, would offset the "pour-over” provisions. Upon decedent’s death, the income of both trusts was to be paid to the widow for life. The trust principal would be reduced by the amounts heretofore indicated.
On May 12, 1971, decedent sought to amend the trust agreement without his wife’s consent, striking the provisions for trust funds A and B and other provisions which would have made possible the qualification for the marital deduction and the charitable deduction. The wife’s testamentary power *440of appointment and Chase Manhattan’s power to invade the principal for the wife’s benefit were eliminated, and the trust corpus was to be paid over to the decedent’s executors and become a part of his estate on the death of the survivor of decedent and his wife. The estate tax provision and the $100,000 "pour-over” provisions remained. It also revoked the appointment of his wife as substitute trustee in place of decedent. By a further amendment dated January 7, 1972, again without the wife’s consent, Chase Manhattan was given the power to borrow money from itself.
On May 12, 1971, decedent also executed a last will and testament in which his wife was not named as a beneficiary. Decedent died November 16, 1972, and subsequently, his widow sought to exercise her right of election to take against the will. Chase Manhattan rejected the widow’s notice of election on the ground that its validity should be judicially determined as well as the effect and extent of such election.
The Surrogate held valid the widow’s exercise of her right of election, the amendments to the trust indenture dated May 22, 1961, and Feburary 15, 1963, and determined that the 1971 and 1972 amendments were such substantial and material changes as to be considered a new trust agreement.
Of the May 12, 1971 amendment, the Surrogate stated, "It was not 'a mere formal change’ in the 1958 trust agreement.” In effect, it transformed the 1958 trust agreement into a testamentary substitute, which satisfied the widow’s recognized right of election in all respects except as to $10,000 which was to be deducted from the principal of the trust (EPTL 5-1.1, subd [c], par [1], cl [c]).
The question on appeal is whether the 1971 and 1972 amendments were valid, and, if so, did the trust agreement become a testamentary substitute so as to be included in the testamentary estate of the decedent. We agree that the widow had a right of election against the will. The problem is to determine the breadth, scope and effect of her exercise of that right.
When the trust was created in 1958, though the parties were not then married, the decedent reserved the right to revoke the trust in whole or in part without anyone’s consent required. A limitation of that right was that no change could be made which reduced the provision for Katherine Rose Kane Walton for her lifetime in section A of article First without her written consent. While the amendment of May *44122, 1961, was without her consent, it chiefly amended as to the ultimate charitable remaindermen. Since the February 15, 1963 amendment was made with the written consent of the decedent’s wife, such consent served not only to validate the substantial changes made in the trust agreement in 1963, but the prior 1961 amendment as well.
As the agreement then stood, the decedent’s wife was entitled to a life income, with a power in Chase Manhattan to invade the principal for her benefit should it deem it necessary. She was clearly a person beneficially interested in the trust whose written consent was necessary to revoke or amend the trust (EPTL 7-1.9; see, also, Matter of Dodge, 25 NY2d 273) except as the settlor had reversed the power to revoke or amend. Additionally, the 1963 amendment made possible the securing of the maximum marital deduction as well as charitable deductions for that portion of the estate left to charity. The decedent’s apparent purpose in these amendments was the reduction of estate taxes. It also seems clear that the provision for a "pour-over” of $100,000 from the trust principal and its invasion and reduction by an amount required to pay certain enumerated taxes reduced the life income payable to Mrs. Walton. However, this reduction was offset to some extent by the provisions dealing with marital and charitable deductions and the wife’s 1963 consent must be viewed in this context. Despite all the changes, the agreement retained the provision which required the written consent of the wife to any amendment which would have the effect of reducing provisions already made for her lifetime in section A of article First.
As noted, the May 12, 1971 amendments concededly made without the wife’s written consent, inter alia eliminated the marital and charitable deductions for estate tax purposes, the wife’s testamentary power of appointment, and the power of the corporate trustee to invade the principal for the benefit of the wife.
At its inception, it was recognized that the trust principal might vary. In addition to the trust assets initially delivered, the trustees agreed "to accept any cash, securities or other property acceptable to them which the settlor may hereafter transfer or deliver.”
Despite changes affecting the principal of the trust, the provision that the decedent’s wife should receive the income from the trust for life remained unchanged. And, while the *442amendments of 1971 and 1972 eliminated the possible balancing offsets of the 1963 amendments, at decedent’s death the trust principal remained substantial and the income thereof sufficient to achieve the settlor’s objective. There was a single, fixed invasion of the trust upon the settlor’s death to which the wife consented and which merely defined the amount of the principal of the trust as of decedent’s death from which she should receive a lifetime income and such act should not be considered potentially destructive of the trust (see Matter of Plimack, 72 Misc 2d 476). The 1971 and 1972 amendments did not further deplete the trust principal, but affected the ultimate disposition of the trust assets. Therefore, since the major 1963 change which affected the life income was consented to, and since the right of decedent’s wife to a life income from the trust continued, the 1971 and 1972 amendments are deemed valid.
EPTL 5-1.1 (subd [b], par [1]) sets forth the criteria for treating inter vivos dispositions as testamentary substitutes for the purpose of election by a surviving spouse. As enumerated by the Surrogate, they are: "(1) the decedent’s will had to be executed after August 31,1966; [in the instant case the will was executed May 12, 1971]; (2) the 'testamentary substitute’ had to be effected after August 31, 1966 [here the trust was established in 1958 and amended substantially in 1963, and again in 1971 and 1972]; and (3) the testamentary substitute had to be effected during marriage [which is the case herein]”. Unless the later amendments of 1971 and 1972 are found to have effected material changes in the trust agreement, they cannot meet the test required for an inter vivos disposition to be considered a testamentary substitute. (See Matter of Agioritis, 40 NY2d 646.) Clearly, the 1971 amendment was more than a mere formal change. It eliminated the possibility of the marital and charitable deductions and left a directed reduction of the trust principal plus the additional obligations of full payment of taxes. This was a substantial change, as was the 1972 amendment which gave additional power to the trustees and provided that, upon the death of the wife, the trust principal was to be paid over to the decedent’s executors as part of his estate. It must be also remembered that at the time of his death and prior thereto, the decedent retained the power to invade the trust or alter the instrument as he saw fit subject only to the certain limitation regarding changes affecting his wife.
*443Thus, under the conditions here present, the inter vivos trust, as amended, was properly considered a testamentary substitute and the inclusion of the trust assets in decedent’s estate is proper. The widow benefits pursuant to the indenture and also pursuant to the right of election. As the Surrogate pointed out "The inter vivos trust is greater in amount than the widow’s elective share. Under its provisions the widow will receive the income for her life. Accordingly, under the express language of the statute, the widow had only the limited right to take the sum of ten thousand dollars absolutely which shall be deducted from the principal of such trust (EPTL 5-1.1 [c] [1] [D]).” We agree. (See, also, EPTL 5-1.1, subd [b], par [1], cl [C] and 5-1.1, subd [c], par [1], cl [F]; Matter of McGrattan, 76 Misc 2d 873.)
Finally, this proceeding involves the validity and the extent of the widow’s right of election, not the construction of a will, and on the present record, the award of $10,000 to the guardian ad litem is excessive.
Accordingly, the award to the guardian ad litem should be modified, on the law, on the facts and in the exercise of discretion, to reduce the amount to $5,000 and, as so modified, the decree should otherwise be affirmed, without costs.
. Subsequent to the argument and submission of this appeal, respondent-appellant, Katherine Rose Kane Walton, died and determination of this appeal was withheld pending substitution of a personal representative for the decedent. By order dated February 25, 1977 (Spiegel, S.), Nicholas R. Doman was substituted as executor of the goods, chattels and credits of Katherine Rose Kane Walton, deceased, as a respondent in this proceeding in place and stead of said decedent.
