OPINION
1 Russell E. Young appeals from the trial court's judgment setting aside a quitclaim deed purporting to transfer Eugene and Zelma B. Davis's farm to him from their trust, and quieting title to the farm in his uncle, Steven R. Davis, the successor trustee. We affirm.
{2 In 1993, Eugene and Zelma Davis (the Davises) creаted the Eugene Davis and Zelma B. Davis Family Living Trust (the Trust), named themselves as trustees, and deeded their farm to themselves as trustees. With respect to the Davises' power to revoke the Trust, the Trust documents provide:
2.01 Powers Reserved by Gramtors. (a) Revocation. While either grantor is living, the trust created by this instrument may be revoked, in whole or in part, by an instrument signed by Grantors, or the survivor of them, and delivered to the Trustees. Upon revocation, the Trustees shall promptly distribute to Grantors, or the survivor of them, all of the designatеd portion of the property comprising the trust estate.
At nearly the same time they executed the Trust documents, the Davises executed reciprocal durable powers of attorney naming each other as attorneys-in-fact and granting to the other "full power to do and perform all and every act that [each] may lawfully do ..., with full power of substitution and revocation."
T3 The Trust documents provided that upon the death of both Davises, Steven would become the successor trustee, each of the Davises' grandchildren would receive $1000, and the remaining Trust assets would then be distributed to the Davises' children-one-third to Steven, one-third to Patricia Ann Zufelt, and one-sixth each to Rex E. and Fay Davis. The parties agree that the farm was the main assеt held by the Trust.
T4 On January 1, 2001, Eugene executed a quitclaim deed conveying the Davises' farm to his grandson, Appellant Russell E. Young, who had long lived on and worked the farm. 1 Zelma did not execute the deed at that time, nor did Eugene sign it on her behalf as her attorney-in-fact. The deed was apparently delivered to Young, but he did not then record it.
T5 On March 12, 2003, Eugene died, leaving Zelma as the sole trustee under the terms of the Trust. Nine days later, she added her signature-or rather, an illegible *25 mark-to the quitelaim deed. Young recordеd the deed three days later. It is unclear whether anyone besides the Davises and Young knew about the quitclaim deed. Zelma died on October 16, 2005.
16 Not surprisingly, contention arose among members of the family regarding the proper disposition of the Davises' farm, with Young claiming it as his own by virtue of the quitclaim deed he had recorded. Ultimately, Steven filed suit to invalidate the purported transfer of the farm to Young and to quiet title to the farm in himself as successor trustee under the terms of the Trust. Young, of course, opрosed the action.
T7 After a three-day bench trial, the trial court entered its judgment, from which Young timely appealed, setting aside the quitclaim deed as void ab initio and quieting title to the Davises' farm in Steven as trustee. In connection with its order, the trial court made a number of oral findings, which are particularly relevant to our consideration of this appeal. See generally Utah R. Civ. P. 52(a) (allowing a trial court to enter oral findings).
T8 First, the trial court recognized that under the common law of Utah, a settlоr has power to modify or revoke a trust only to the extent the trust documents allow, and only in the particular manner or cireumstances allowed by the documents' terms. See Flake v. Flake,
T9 Second, the trial court held that the Utah Uniform Trust Code did not apply to this case because it was not enacted until 2004, see Utah Code Ann. $ 75-7-605 (Supp.2006) (as enaсted by 2004 Utah Laws, ch. 89, § 70). These first two issues present legal questions, which we review for correctness. See State v. Pena,
"I 10 Third, the trial court specifically found that- Eugene, in signing the quitclaim deed, did not act as Zelma's attorney-in-fact. Fourth, the trial court found that thе Davises did not intend to give Young their farm without consideration. These two issues raise questions of fact that we review for clear error. See id. at 985-36.
T 11 Fifth, the trial court specifically found that the Davises and Young enjoyed a confidential relationship, аnd that because of that relationship there existed a presumption of undue influence on the part of Young. See Webster v. Lehmer,
12 The crux of Young's argument on appeal is this: Either the quitclaim deed, as an instrument signed by both Eugene and Zelma, served both to partially revoke the Trust and to convey the Davises' farm to him in accordance with their long-held wishes, or Eugene, acting alone, effected the same result by executing the deed himself. Both prongs of Young's argument stand or fall with the validity of the quitclaim deed and the answer to whether its execution consti *26 tutes an effective revocation or transfer under the terms of the Trust.
113 We begin our analysis with the facts. Under our rules, a party challenging a factual finding "must first marshal all record evidence that supports the challenged finding." Utah R.App. P. 24(a)(9). "When an appellant fails to meet the heavy burden of marshaling the evidence, ... we assumel[ ] that the record supports the findings of the trial court." Moon v. Moon,
' 14 We next proceed to consider the legal question that stands independently of these fact-driven issues. Young insists that the Utah Uniform Trust Code as enacted in 2004 applies. We need not definitively resolve this question because, in light of thе trial court's factual findings, Young's argument fails under both the common law and the new code provisions.
115 Under Utah common law, a set-tlor has power to modify or revoke a trust only to the extent the trust documents permit, and only in the particular manner or сireumstances identified as allowable under the terms of the trust documents. See Flake v. Flake,
[ 16 Under the terms of the Trust, it could be revoked while both Eugene and Zelma were alive only "by an instrument signed by Grantors." - By its own terms, then, revocation of the Trust required the execution of an appropriate instrument by both Eugеne and Zelma. The trial court found, on the one hand, that Zelma lacked the mental capacity to execute the quitclaim deed, and on the other, that Young's undue influence otherwise invalidated the deed, at least insofar as Zelma's execution of it was concerned. It also found that Eugene did not sign the quitclaim deed as Zelma's attorney-in-fact. Given these findings, the quitclaim deed cannot satisfy the terms of the Trust, either strictly or substantially.
117 Finally, Young argues that under the code, Eugene's signature was itself suffiсient to satisfy the terms of the Trust doeu-ments. In support of his argument, he relies
*27
upon section 75-7-605(2)(a), which allows a revocable trust created or funded by more than one settlor to be revoked by either spouse acting alone to the extent the trust consists of community property. See id. § T5-T-605(2)(a). - But subsection (2)(a) speaks only to the authority of a single spouse to revoke a trust, while subsection (8) speaks to the method by which the trust can be revoked. Were we to read subsection (2)(a) in isolation, as Yоung proposes, we would essentially ignore the related provisions of subsection (8), discussed above. The well-accepted rules of statutory construction require us to read the various parts of seetion 75-7-605 together. See Lund v. Brown,
118 Young also relies on the Trust's substitute trustee provisions to support his argument that Eugene's signature alone satisfies the terms of the Trust documents. Section 3.01 of the Trust provides: "If either of the [Davises] fail or cease to serve for any reasons, the other may serve alone." Again, this Trust provision speaks only to the authority of a trustee to act alone under certain circumstances. "A trust is a form of ownership in which the legal title to property is vеsted in a trustee, who has equitable duties to hold and manage it for the benefit of beneficiaries." Continental Bank & Trust Co. v. Country Club Mobile Estates, Ltd.,
119 The Trust expressly provided a method for revоking the Trust, and Eugene, whether acting as grantor or trustee, was bound to follow it. He failed to do so. Accordingly, we affirm the decision of the trial court setting aside the quitclaim deed as void ab initio and quieting title to the Davises' farm in Steven, the successor trusteе.

Notes
. In 1993, the Davises had executed codicils to their wills that provided Young with a one-quarter interest in their residuary estate. In 1997, the Davises executed a joint codicil giving Young an additional $5000 cash gift "for the help caring for us." Though insightful as bearing on the favored status Young enjoyed, these facts are essentially irrelevant to our review of the issues surrounding the Trust.
