Appellants challenge the trial court’s decision permitting the trustee of two trusts established for the benefit of one beneficiary to transfer funds from one trust to another trust, in order to reimburse the latter trust for expenditures made on the beneficiary’s behalf. The trust instruments direct that the trust from which the funds originally were paid is not the primary source for expenditures to benefit the beneficiary, but rather is the secondary source. The primary source for such expenditures is the trust from which reimbursement was sought. Pretermitting whether the trustee violated its fiduciary duties by failing to follow the trust instruments’ directives, the payments, had they been paid out of the primary trust, would have been authorized and for a proper purpose. Moreover, by allowing the trustee to transfer funds from one trust to another, the trial court did not disturb the grantor’s overall scheme of disposition and testamentary intent. Therefore, we agree with the trial court that the trustee could reimburse funds paid out of the secondary trust from the primary trust, and we affirm.
In 1984, Roy P. Otwell, Sr., (“Otwell, Sr.”) created an inter vivos trust in which the First National Bank of Gainesville (“The Bank”) was appointed trustee. The trust instrument authorizes the Bank to pay all or any part of trust income to Roy Otwell, Jr. (“Otwell, Jr.”), or, alternatively, to accumulate such income as trust principal. If necessary, the Bank also is authorized to encroach upon the inter vivos trust’s corpus to provide for Otwell, Jr. The inter vivos trust grants the Bank, as trustee, “power to do all things and to execute such instruments as may be deemed necessary or proper, including the powers enumerated in [Ga. L. 1973, pp. 846-856].”1 Upon Otwell, *548Jr.’s death, the inter vivos trust directs the Bank as trustee to distribute any remaining corpus equally among Otwell, Jr.’s two adult children, or, if they are deceased, to their descendánts. Otwell, Jr. has been declared legally incompetent, and his two children are his appointed guardians.
In 1987, Otwell, Sr. executed his last will and testament, in which he directed that upon his death, one quarter of his estate was to be placed in a testamentary trust for the benefit of Otwell, Jr. The remaining three quarters of Otwell, Sr.’s estate was devised to his three daughters, Otwell, Jr.’s siblings. After Otwell, Sr. died in 1988, a caveat was filed against his will by Otwell, Jr. and his children, who had not been mentioned in their grandfather’s will. In order to resolve the caveat, a consent order .was entered that modified the terms of both Otwell, Sr.’s will and the testamentary trust.* 2 The will was modified to devise $100,000 each to Otwell, Jr.’s children, and to place Otwell, Sr.’s home in trust, with the Bank as trustee, for Otwell, Jr. to reside therein until his death, at which time the home will pass to his two children. Provision also was made to pay over a quarter of a million dollars in attorney and administrative fees out of the estate.
The consent order modified the terms of the testamentary trust to authorize the Bank to expend testamentary trust income for Otwell, Jr.’s benefit in those years in which his income from other sources, including the inter vivos trust, is insufficient to maintain him. Such income expenditures from the testamentary trust are authorized only when Otwell, Jr.’s income from other sources has been depleted; excepting that, regardless of whether Otwell, Jr.’s income from other sources has been depleted, the Bank is authorized to use testamentary trust income to pay for (1) taxes and insurance on Otwell, Jr.’s home, (2) Otwell, Jr.’s hospitalization and health care, and (3) extraordinary homeplace maintenance expenses.3 Testamentary trust principal may be invaded only after all other available principal and income has been depleted, and the testamentary trust (as modified) expressly states that its principal should remain constant unless and until the principal of the inter vivos trust is depleted. Upon Otwell, Jr.’s death, any remaining corpus of the testamentary trust is to be divided equally among his two children and his *549three siblings.
Otwell, Sr. died in 1988. In the five years that followed, the Bank made considerable expenditures, alleged to exceed $225,000, primarily to renovate Otwell, Sr.’s home, which had fallen into disrepair, before Otwell, Jr. and his caretakers took up residency. The expenditures were paid directly from the portion of Otwell, Sr.’s estate intended to fund the testamentary trust. However, during those five years, the testamentary trust was not established, as instructed in Otwell, Sr.’s will. The Bank states that the expenditures it paid from the estate exceeded the income of the testamentary trust assets, as calculated based upon one-fourth of the entire estate’s value, and thus had to be charged against assets designated for the testamentary trust’s principal. In order to rectify the depletion of testamentary trust principal, the Bank sought to transfer funds from the corpus of the inter vivos trust to the testamentary trust. Otwell, Jr.’s children, acting on their own and on his behalf, opposed that transfer.
It was not until 1993 that the testamentary trust was funded. In 1995, the Bank filed a declaratory judgment action concerning its administration of the estate and the trusts, and the trial court granted the Bank partial summary judgment authorizing it to transfer funds from the inter vivos trust to the testamentary trust in order to cover the expenditures made from estate funds eventually used to establish the testamentary trust. Otwell, Jr.’s children, acting on their own and on his behalf (“Appellants”), appeal from that ruling, claiming that the Bank did not have authority to transfer the funds.
1. At the outset, we note that Appellants also claim that the Bank has breached its fiduciary obligations by, among other things, (1) failing to comply with the trust instruments’ directives; (2) not establishing the testamentary trust until August 1993; (3) not using inter vivos funds before expending Otwell, Jr.’s share of the estate; (4) not limiting its spending on Otwell, Jr.’s behalf in a reasonable manner; and (5) attempting to disperse less than equal shares to Otwell, Sr.’s children. In granting partial summary judgment affirming that the Bank had the authority to reimburse the testamentary trust from the inter vivos trust, the trial court reserved ruling on whether the Bank had violated its fiduciary duties, as alleged by Appellants. That particular issue remains pending before the trial court.
Likewise, in reviewing the trial court’s ruling authorizing the Bank to transfer money from one trust into another, this Court does not decide whether the Bank properly discharged its fiduciary obligations, and Appellants’ claims of fiduciary breach are not considered as part of this appeal.
2. Appellants argue that the terms of the inter vivos trust only *550permit payments to be made for the benefit of Otwell, Jr., and that those terms do not authorize the Bank to transfer funds to the testamentary trust. Furthermore, they claim that the testamentary trust does not permit expenditures from trust principal until all other sources of principal ¿nd income have been depleted. Therefore, Appellants argue, the disbursements made by the Bank were unauthorized, and the Bank should not be permitted to correct its error by replenishing the testamentary trust with another trust’s funds.
This argument, however, obscures the real issue. Pretermitting whether the Bank violated its fiduciary obligation to follow the trust instruments’ directives, it is undisputed that inter vivos trust income and principle could have been expended for the benefit of Otwell, Jr. No party to this appeal claims that the contested expenditures at issue were made for anything other than Otwell, Jr.’s benefit. The issue thus becomes whether, having made payments out of estate funds intended to establish the testamentary trust, the Bank can reimburse that trust from the inter vivos trust. Because the money expended was used for a purpose that it could have been used for, had it been paid directly from the inter vivos trust, we agree with the trial court that the Bank may reimburse the testamentary trust from the inter vivos trust. Put another way, had the Bank made the contested expenditures directly from the inter vivos trust, using income first and then principal, there would be no dispute regarding their propriety. Thus, by paying money for a proper purpose from a secondary source, and then reimbursing that source from the inter vivos trust, the Bank has not taken from Appellants what they would otherwise be entitled to.
Appellants, however, allege that the money left by Otwell, Sr. for the benefit of Otwell, Jr. has been substantially depleted by the Bank, and would have this Court order the Bank to reimburse the testamentary trust out of its own funds, and leave the inter vivos trust untouched. At the same time, however, Appellants concede that the expenditures were for the benefit of Otwell, Jr., and thus were made by the Bank for a purpose permitted by the trusts. Clearly, then, were we to order the Bank to reimburse the testamentary trust with the Bank’s own funds, the Bank itself would be paying for Otwell, Jr.’s care, despite Otwell, Sr.’s ample provision for such. That would provide Appellants with an enormous windfall.4
Appellants also claim that the trial court’s order permits the Bank to treat two trusts with “different beneficiaries” as one trust, to *551the detriment of the purported “beneficiaries” of the inter vivos trust — Otwell, Jr.’s children. While it is true that Otwell, Jr.’s children have a 50 percent interest in any remaining corpus of the inter vivos trust, and only a 20 percent interest in the testamentary trust corpus, those interests are entirely subordinate to the overall testamentary scheme established by Otwell, Sr. to provide for Otwell, Jr. — the trusts’ primary beneficiary — with trust income and principal. Moreover, Otwell, Jr.’s children are parties to the consent order establishing them as second-line beneficiaries with only a 20 percent interest in the latter trust, and they cannot complain of that status on appeal.5
3. Appellants argue that a trustee is prohibited from recovering payments made on behalf of a beneficiary where the beneficiary “has so changed his position that it is inequitable to compel him to make repayment.”6 This established principle is not applicable to this case, however, as it concerns instances where a trustee has either made overpayments, paid out money mistakenly, or has made payments to which a beneficiary was not entitled.7 Those facts simply do not exist in this case. Moreover, the record reveals that Appellants were provided with periodic accounting statements showing that the expenditures at issue were being made, and thus had knowledge of the payments, and at least tacitly acquiesced to them.
Furthermore, we noté that at the time of Otwell, Sr.’s death, the estate was comprised primarily of real property and held very little liquid assets. In the years immediately following Otwell, Sr.’s death, had the Bank relied solely upon the inter vivos trust for funds with which to care for Otwell, Jr., then that trust’s liquid assets might well have been depleted. Appellants concede that would have created an undesirable situation where there was no “cash cushion” to ensure for Otwell, Jr.’s care in case of a medical emergency. In that regard, the record shows that, shortly after Otwell, Sr.’s death, Appellants expressed their concern to the Bank that sufficient liquid assets be kept available to care for Otwell, Jr., and to ensure that, if a medical emergency arose, the estate’s real property holdings would not have to be sold hastily, for low prices. All of these factors lead us to reject Appellants’ request that the Bank be equitably estopped from replenishing the testamentary trust with inter vivos trust funds.8
4. Finally, we note that the contested expenditures did not alter *552the overall testamentary scheme established by Otwell, Sr. — which was to provide for Otwell, Jr. throughout his lifetime.9 As explained above, the contested expenditures were ultimately charged against the inter vivos trust, and the Bank, as trustee, was vested with discretion to encroach upon that trust in order to provide for Otwell, Jr.’s care. A court may interfere with a trustee’s exercise of its discretion only to correct an abuse thereof, or upon evidence of bad faith or fraud.10 By indirectly encroaching upon the inter vivos trust — first using estate funds intended to establish a separate trust, and then replenishing those funds from the inter vivos trust — the Bank may not have acted in accordance with the grantor’s directives, but we do not believe it abused its discretion or acted in bad faith.
Judgment affirmed.
All the Justices concur, except Benham, C. J, Hunstein and Carley, JJ, who dissent.
