PREGERSON, Circuit Judge:
This case arises under the Employee Retirement Income Security Act of 1974 (ERISA), as amended by the Retirement Equity Act of 1984 (“REA”). The REA was designed to protect the financial security of ex-spouses and dependants after divorce. See Boggs v. Boggs, 520 U.S. 833, 845, 117 S.Ct. 1754, 138 L.Ed.2d 45 (1997); Ablamis v. Roper, 937 F.2d 1450, 1453 (9th Cir.1991). When Appellant Shirley Stewart divorced Richard Nielsen in [1147]*11471989, a California court issued a Marital Dissolution Order, which, inter alia, awarded Stewart her community property share in Nielsen’s interest in an ERISA profit sharing pension plan (“the ERISA Plan”). At that time, Nielsen was not only a participant in the ERISA Plan, but also one of the Plan’s four trustees, with fiduciary responsibility for its administration.
Despite Stewart’s right to receive her community property share in Nielsen’s interest in the ERISA Plan, defendants Thorpe Holding Company (Nielsen’s former employer), Thorpe Holding Company Profit Sharing Plan (the ERISA Plan), and Thomas A. Carpenter (one of four trustees of the ERISA Plan with fiduciary responsibility for its administration) failed to distribute to Stewart her share in Nielsen’s interest in the ERISA Plan. Instead, they distributed to Nielsen his entire interest in the ERISA Plan.
Stewart brought this action, seeking her share of Nielsen’s interest in the ERISA Plan. The district court granted summary judgment for the defendants. The court summarily ruled that Stewart lacked standing to bring her ERISA claim because her Marital Dissolution Order purportedly did not satisfy some of the requirements of a “Qualified Domestic Relations Order” (QDRO) under ERISA.
Because we conclude that Stewart does have standing to bring her claim under the facts of this case, we reverse the district court’s grant of summary judgment. Any arguable defects in the Marital Dissolution Order’s language were not fatal. The Marital Dissolution Order does qualify as a QDRO as a matter of law. Even assuming that the Marital Dissolution Order failed to qualify as a QDRO, Stewart nevertheless has standing to bring this action because, by failing to perform their fiduciary duties under ERISA, defendants denied Stewart the opportunity to protect her rights and interests as an alternate payee under 29 U.S.C. § 1056(d)(3)(G), (H).
I.
BACKGROUND
On July 24, 1989, Shirley Stewart2 divorced Richard C. Nielsen pursuant to a Marital Dissolution Judgment and Order of the Los Angeles County Superior Court. The Marital Dissolution Order incorporated the executory terms of the Marital Settlement Agreement signed by Nielsen and Stewart. It awarded Stewart, inter alia, a one-half community property share in Nielsen’s interest in the ERISA Plan.3 At the time of the divorce, Nielsen was an employee of Defendant Thorpe Holding Company (“Thorpe Holding”), a participant in Thorpe Holding’s ERISA Plan, and one of the Plan’s four trustees, with fiduciary responsibility for its administration.
Two months after the Marital Dissolution Order was filed in state court, Defendant Thomas A. Carpenter (“Carpenter”), one of the Plan’s other trustees, wrote a letter to Kemper Financial Services (the mutual fund holder for the Plan) at Nielsen’s request, asking Kemper to transfer 9,225.197 shares (or half of the shares in the ERISA pension account) from Nielsen’s pension account to Stewart. Carpenter’s letter included Stewart’s current mailing address of 8109 Michigan Avenue, Whittier, CA 90602. This mailing address corresponded to the address of the family residence awarded to Stewart by the Marital Dissolution Order. For reasons unknown, the transfer was never made. Stewart apparently had no knowledge of Carpenter’s letter to Kemper. Moreover, [1148]*1148the record suggests that the defendants had no further contact with Stewart until, at the earliest, April of 1990.
In March 1991, Stewart contacted Carpenter concerning the transfer of her community property interest in the ERISA Plan. On May 8, 1991, Carpenter wrote Stewart a letter informing her that she needed to complete “an application” before the transfer could be made. Carpenter’s letter made no reference to the Marital Dissolution Order, to the requirements under ERISA for a valid QDRO, or to the Plan’s procedures for determining whether it constituted a valid QDRO.
In early 1992, Nielsen retired from Thorpe Holding and requested that his pension account be liquidated. On December 14, 1992, Carpenter directed the ERISA Plan’s portfolio manager to transfer half of the shares in Nielsen’s ERISA pension account to Nielsen’s personal I.R.A. account and to “liquidate the remaining shares” and distribute the proceeds to Nielsen directly. Defendants thus distributed to Nielsen the entire ERISA pension account, including those shares awarded to Stewart by the Marital Dissolution Order, despite their knowledge of her adjudicated right to those shares.
Stewart filed an action in district court on March 28,1997, seeking her community property share in Nielsen’s interest in the ERISA plan pursuant to the Marital Dissolution Order. Thorpe Holding filed a motion for summary judgment, alleging, inter alia, that the Marital Dissolution Order was not a QDRO within the meaning of ERISA and that Stewart lacked standing to assert her claim in federal court. The district court granted summary judgment in favor of Thorpe Holding and dismissed Stewart’s action for lack of standing. Stewart timely appeals. We have jurisdiction over the final decision of the district court under 28 U.S.C. § 1291.

STANDARD OF REVIEW
Standing is a question of law reviewed de novo. See Schultz v. PLM Int’l, Inc., 127 F.3d 1139, 1141 (9th Cir.1997). Summary judgment is also reviewed de novo. See Robi v. Reed, 173 F.3d 736, 739 (9th Cir.1999). ‘Viewing the evidence in the light most favorable to the nonmoving party, [we] determine! ] whether there are any genuine issues of material fact and whether the district court correctly applied the relevant substantive law.” Id. The district court’s “interpretation of ERISA is a question of law reviewed de novo.” Wetzel v. Lou Ehlers Cadillac Group Long Term Disability Ins. Program, 189 F.3d 1160, 1163 (9th Cir.1999). The district court’s findings of fact are reviewed for clear error. See Fed.R.Civ.P. 52(a); Lawyer v. Department of Justice, 521 U.S. 567, 580, 117 S.Ct. 2186, 138 L.Ed.2d 669 (1997).

DISCUSSION
A. Historical Overview of ERISA
A brief overview of ERISA’s design is necessary to put Stewart’s and the defendants’ contentions in the proper context.
Congress enacted the Employee Retirement Income Security Act of 1974 to establish a comprehensive federal scheme for the protection of pension plan participants and their beneficiaries. See American Tel. & Tel. Co. v. Merry, 592 F.2d 118, 120 (1979). Its “most important purpose” was to “assure American workers that they may look forward with anticipation to a retirement with financial security and dignity, without fear that this period of life will be lacking in the necessities to sustain them as human beings within our society.” Smith v. Mirman, 749 F.2d 181, 182 (4th Cir.1984) (quoting from S.Rep. No. 93-127, 93d Cong., 2d Sess. (1974), reprinted in U.S.C.C.A.N., at 4639, 4849 (1974)) (internal quotation marks omitted). To ensure that an employee’s accrued benefits would be available upon retirement, ERISA requires all plans to include anti-assignment provisions. See 29 U.S.C. § 1056(d)(1) (1990).
[1149]*1149Further, ERISA’s preemption provision specifically provides that ERISA super-cedes any state law regarding employee benefit plans. See 29 U.S.C. § 1144(a) (1985). In light of ERISA’s preemption and anti-assignment provisions, the question initially arose whether ERISA prevented state courts from entering domestic relations orders that sought to garnish retirement benefits to enforce alimony or child support obligations. See generally Tenneeo, Inc. v. First Virginia Bank of Tidewater, 698 F.2d 688 (4th Cir.1983). The majority of courts addressing this issue concluded that ERISA did not prevent such assignments. See, e.g., Operating Engineers’, etc. v. Zamborsky, 650 F.2d 196, 198 (9th Cir.1981); Stone v. Stone, 632 F.2d 740, 743 (9th Cir.1980) (holding that a former spouse has standing to bring a claim to enforce a state community property division).
Congress resolved any uncertainty concerning the authority of state courts to adjudicate marital dissolutions and to affect ERISA pension plan benefits, when it enacted the Retirement Equity Act of 1984, Pub.L. 98-397, 98 Stat. 1426 (codified as amended 26 U.S.C. § 417). The REA amended ERISA by creating an exception to its anti-assignment provisions for state “domestic relations orders” (commonly known as marital dissolution orders) that meet the requirements of a “qualified domestic relations order” or QDRO. See 29 U.S.C. § 1056(d)(3)(A).
The QDRO exception was specifically enacted to protect the financial security of ex-spouses. See Ablamis, 937 F.2d at 1453 (so holding). In creating the QDRO mechanism, Congress was careful to provide that an “alternate payee under a qualified domestic relations order,” i.e., an ex-spouse, is to be considered an ERISA plan “beneficiary.” See 29 U.S.C. § 1056(d)(3)(J); see also Boggs, 520 U.S. at 845, 117 S.Ct. 1754 (so holding). Moreover, Congress was careful to define an “alternate payee” as “any spouse, former spouse, child, or other dependent of a participant who is recognized by a domestic relations order as having a right to receive all, or a portion of, the benefits payable under the plan with respect to such participant.” 29 U.S.C. § 1056(d)(3)(E). “These provisions are essential to one of REA’s central purposes, which is to give enhanced protection to the spouse and dependent children in the event of divorce or separation.... ” Boggs, 520 U.S. at 847, 117 S.Ct. 1754.
According to 29 Ü.S.C. § 1056(d), a state court’s domestic relations order relating to spousal property rights is a QDRO if it “creates or recognizes the existence of an alternative payee’s right to ... receive all or a portion of the benefits payable” under a plan. 29 U.S.C. § 1056(d)(3)(B)(i)(I). To qualify under the statute, a marital dissolution order must specify:
(i) the name and the last known mailing address (if any) of the participant and the name and mailing address of each alternate payee covered by the order,
(ii) the amount or percentage of the participant’s benefits to be paid by the plan to each such alternate payee, or the manner in which such amount or percentage is to be determined,
(iii) the number of payments or period to which such order applies, and
(iv) each plan to which such order applies.
29 U.S.C. § 1056(d)(3)(C)(i)-(iv) (emphasis added).4 These requirements primarily ensure that the payee designated by the domestic relations order is a legitimate [1150]*1150alternate payee and that the domestic relations order does not increase the payment burden on the plan or mandate the assignment of benefits previously assigned by another QDRO. See 29 U.S.C. § 1056(d)(3)(B), (H)(i). Indeed, “[t]he purpose [of the specificity requirements] is to reduce the expense of ERISA plans by sparing plan administrators the grief they experience when because of uncertainty concerning the identity of the beneficiary they pay the wrong person, or arguably the wrong person, and are sued by a rival claimant.” Metropolitan Life Ins. Co. v. Wheaton, 42 F.3d 1080, 1084 (7th Cir.1994) (citing Carland v. Metropolitan Life Ins. Co., 935 F.2d 1114, 1120 (10th Cir.), cert. denied, 502 U.S. 1020, 112 S.Ct. 670, 116 L.Ed.2d 761 (1991)) (emphasis added).
B. The Marital Dissolution Order is a Valid QDRO
In the present case, there is absolutely no “uncertainty concerning the identity of the beneficiary” under the Marital Dissolution Order. The Order clearly identifies Stewart as the “alternate payee” because it provides for her entitlement as Nielsen’s ex-spouse to one-half of the community property interest in his ERISA pension plan. See Hawkins v. Commissioner of Internal Revenue, 86 F.3d 982, 990 (10th Cir.1996) (deeming the ex-spouse of an ERISA plan participant an “ ‘alternate payee’ because the [marital settlement] Agreement gives her the right to receive ‘all, or a portion of,’ [the participant spouse’s ERISA] Plan benefits”); see also 29 U.S.C. § 1056(d)(3)(E) (defining an “alternate payee” as “any spouse, former spouse, child, or other dependent of a participant who is recognized by a domestic relations order as having a right to receive all, or a portion of, the benefits payable under the plan with respect to such participant”).
In addition, the Marital Dissolution Order awards the family residence to Stewart and sets forth its address. The Order further states the percentage of the benefits to be paid to Stewart (“one-half of the community interest”), the period affected by the Order (from the date of marriage through the date of separation (“1-1-88”) “[p]ursuant to In re Brown, 15 Cal.3d 838, 841-43, 126 Cal.Rptr. 633, 544 P.2d 561 (1976)” (en banc)), and the plan to which the Order applies (“Thorpe Holding Company PS Plan”). The Marital Dissolution Order also states the exact number of shares in the Plan that constitute the community property interest (“17,295.47”) and the value of each share as of March 15, 1989 (“$9.70”). The Marital Dissolution Order therefore satisfies the four requirements of a QDRO under ERISA.5
Nevertheless, the district court summarily ruled that the Marital Dissolution Order was not a QDRO on the grounds that it did “not contain the alternate payee’s (Plaintiffs) mailing address, nor the period to which such order applies.” 6 The court — and the dissent — ap-[1152]*1152torney. Moreover, two months after the Marital Dissolution Order was issued, defendant Carpenter wrote a letter to Kem-per Financial Services, the mutual fund holder of the ERISA Plan, instructing it to transfer 9225.197 shares to Stewart at 8109 Michigan Avenue, Whittier, CA 90602. This is the address of the family residence that was awarded to Stewart in the Order. Moreover, Carpenter, at Nielsen’s request, also wrote a' letter to Stewart at this address on May 8,1991 concerning the transfer of shares owed to her. Thus, even though Stewart’s address was not explicitly designated as her “current mailing address” in the Marital Dissolution Order, the Order stated her address, and it is clear that Nielsen, Carpenter, and Thorpe Holding knew it. [1151]*1151parently agreed with defendants that any arguable defect in the precise language of a “domestic relations order” precluded its designation as a QDRO under ERISA. Relevant case law and the history of the QDRO provisions strongly suggests that the district court was badly mistaken in exalting form over substance.
1. Stewart’s Mailing Address Is Sufficiently Provided in the Marital Dissolution Order
The Marital Dissolution Order states that Stewart is to be awarded the family residence. The address for the family residence is stated in the Marital Dissolution Order as 8109 Michigan Avenue, Whittier, California. Thus, Nielsen as Stewart’s ex-husband — and also as a Plan trustee and fiduciary — knew Stewart’s address because he executed the Marital Settlement Agreement that is incorporated into the Marital Dissolution Order. His conduct as one of the Plan trustees in the weeks and months following the execution of the Marital Settlement Agreement further attests to his, and therefore the Plan’s, knowledge of Stewart’s mailing address. For example, the letter that he directed Carpenter to send to Stewart two months after the divorce was sent to the address of the family residence that the Marital Dissolution Order awarded to Stewart.
The fact that the Marital Dissolution Order does not formally declare the family residence’s address as Stewart’s current mailing address is not a fatal defect. The legislative history of § 1056(d)(3)(C) makes this clear:
The Senate committee intends that an order will not be treated as failing to be a qualified order merely because the order does not specify the current mailing address of the participant and alternate payee if the plan administrator has reason to know that address independently of the order.
S.Rep. No. 575, 98th Cong., 2d Sess., reprinted in 1984 U.S.C.C.A.N., at 2547, 2566 (emphasis added).
Moreover, courts that have ruled on this issue have liberally interpreted the address requirement for a valid QDRO in light of its purpose as an “aid [to] plan administrators in identifying and locating alternate payees under a QDRO.” Tolstad v. Tolstad, 527 N.W.2d 668, 673 (N.D. 1995). Thus, where the address of the alternate payee is “known to the plan administrator” or the plan administrator “has reason to know it independently from ... sources readily available to him,” the address requirement for a QDRO is satisfied. Stinner v. Stinner, 520 Pa. 374, 554 A.2d 45, 49, cert. denied, 492 U.S. 919, 109 S.Ct. 3245, 106 L.Ed.2d 591 (1989); accord In re Williams, 50 F.Supp.2d 951, 959-60 (C.D.Cal.1999) (ruling that ERISA’s QDRO mailing address requirement is satisfied where, as here, the address of the participant’s attorney only appears on the divorce judgment and the participant and ex-spouse were in contact with each other after the divorce); Tolstad, 527 N.W.2d at 673 (ruling that ERISA’s QDRO mailing address requirement is satisfied where “a letter in the record from [the ERISA plan administrator] to [the ex-spouse’s] attorney demonstrates that [the ERISA plan administrator] was able to contact [her]”). Simply put, “[b]ut for the lack of one easily-ascertainable address, the rights of the alternate payee should not be lost.” Stinner, 554 A.2d at 49.
Here, the Marital Dissolution Order clearly states the address of Nielsen’s at-
[1152]*11522. The Percentage to be Paid and the Period of Time to Which the Order Applies Are Sufficiently Stated Therein
The Marital Dissolution Order specifies that Stewart is to receive “one-half of the community interest” in Nielsen’s ERISA plan. It further indicates that the period to which the Order applies is from the time of the marriage through the date of separation on January 1, 1988. The dissent’s suggestion that the Order’s “most serious defect” is its purported failure to specify “the amount or percentage of the participant’s benefits to be paid by the plan to each such alternate payee, or the manner in which such amount or percentage is to be determined,” 29 U.S.C. § 1056(d)(8)(C)(ii), as well as its related [purported] failure to indicate “the period to which such order applies,” id. § 1056(d)(3)(C)(iii), is particularly hollow given these facts and the Order’s explicit reference to the seminal California case of In re Brown, 15 Cal.3d 838, 126 Cal.Rptr. 633, 544 P.2d 561 (1976) (en banc).
The California Supreme Court held in In re Brown that “[p]ension rights, whether vested or not, represent a property interest; to the extent that such rights derive from employment during coverture, they comprise a community asset subject to [equal] division in a dissolution proceeding.” 15 Cal.3d at 842, 126 Cal.Rptr. 633, 544 P.2d 561 (emphasis added). Therefore, “the community owns all pension rights attributable to employment during the marriage.” Id. And “the period when the parties were married and living together” (which ends on the date of legal separation) is thus the period of time during which a marital dissolution order applies. Id. at 843, 126 Cal.Rptr. 633, 544, P.2d 561.
In this case, according to the terms of the Nielsen’s ERISA Plan, the Plan did not provide for periodic payments of benefits, but instead was a “defined contribution plan” that required the employer to make annual contributions and to segregate each participant’s interest into separate and discrete pension accounts. Upon the termination of Nielsen’s employment, the ERISA pension account would be (and was in fact) closed, and its proceeds distributed to Nielsen in full. Thus, because no periodic payments were contemplated, there was no need for the trial court to determine the number of payments affected by the order. Instead, because the number of shares in Nielsen’s ERISA account and their value could be readily ascertained, the trial court here determined, pursuant to the parties agreement, that 17,295.47 shares constituted the community portion of Nielsen’s pension account as of the date of separation or January 1, 1988, and that each share had a value of $9.70 as of March 15, 1989. According to the Marital Dissolution Order, Stewart and Nielsen entered into the Marital Settlement Agreement on March 16, 1989, “at the time of trial.” Because “each party [was] awarded one-half the shares,” Stewart was therefore clearly entitled to $83,-882.98 or 8,647.73 shares as of “the time of trial.” Cf. In re Bergman, 168 Cal.App.3d 742, 748 n. 4, 214 Cal.Rptr. 661 (1985) (“[T]he present value of a defined contribution plan at dissolution ... is the amount of contributions made between the marriage and separation, plus accruals thereon, and all accruals thereon between the date of separation and trial of the issue.”).
[1153]*1153Accordingly, the district court’s finding that the Marital Dissolution Order failed to determine “the period to which [it] applies,” for purposes of qualifying as a valid QDRO under ERISA is mistaken. To qualify as a valid QDRO under ERISA, a domestic relations order must meet certain criteria. That criteria has been met in this case. To require more specificity than the statute itself requires “ ‘would defeat the purpose of the .[ERISA] provision ... ”’ Metropolitan Life Insurance Co. v. Marsh, 119 F.3d 415, 422 (6th Cir. 1997) (quoting Wheaton, 42 F.3d at 1085).7
3. Relevant Case Law
The Supreme Court held in Boggs that ERISA’s QDRO provisions were designed to protect the community property rights of ex-spouses like Stewart in ERISA pensions. See 520 U.S. at 847, 117 S.Ct. 1754. “These provisions are essential to one of REA’s central purposes, which is to give enhanced protection to the spouse and dependent children in the event of divorce or separation .... ” Id. (emphasis added). We have also recognized that ERISA’s QDRO provisions were enacted because “Congress was ... concerned with the inequities that might be suffered by women who are the economic victims of divorce or separation” and determined that these provisions were necessary “[t]o protect their interests.” Ablamis, 937 F.2d at 1454.
For this reason, other circuit courts have liberally construed the criteria by which a domestic relations order will qualify as a QDRO. See, e.g., Marsh, 119 F.3d 415; Wheaton, 42 F.3d 1080; see also WILLIAM P. HOGOBOOM & DONALD B. KING, CAL. PRAC. GUIDE: FAM. LAW ¶ 10:465.1b (The Rutter Group 1998) (“While there is some disagreement over the extent to which [the Tax Code’s and ERISA’s] specificity requirements may be relaxed, the cases in this area all seem to allow some degree of latitude.” (citing Hawkins, 86 F.3d at 992-93)). In Marsh, the Sixth Circuit held that a divorce decree, which simply stated that the participant’s two children were to receive two-third’s of the participant’s ERISA life insurance policy “substantially complied with ERISA’s requirements.” 119 F.3d at 422. Although the children’s “current mailing addresses” were not included in the order, the divorce decree provided “the address of the mother in whose custody they were placed.” Id. Thus, according to the Sixth Circuit, ERISA’s address requirement was met. See id.; accord Wheaton, 42 F.3d at 1084 (holding same). The decree also identified Metropolitan Life Insurance as the company issuing the ERISA policy to which it applied, so that requirement under ERISA was met. See id. Moreover, because “the decree was very clear regarding the percentage [the two children] should receive” in accordance with ERISA’s requirements, any further questions the administrator had concerning the division of the proceeds between the children could be easily resolved under governing state law principles. Id. at 422 (citing Wheaton, 42 F.3d at 1085). Finally, despite the fact that the decree did not specify the “number of payments or periods for which such order applies,” it still qualified as a QDRO under ERISA because, like Nielsen’s defined contribution plan, the policy contemplated one payment in full. See id. To the Sixth Circuit, the decree lacked “no essential information”; “it [was] clear what [it] intended to be.” Id. It therefore constituted a valid QDRO under ERISA. See id.
[1154]*1154Similarly, in Wheaton, the Seventh Circuit held that a divorce decree that failed explicitly to name the plan to which the order pertained, and failed to specify how the proceeds were to be divided between alternate payees, nevertheless, was sufficient to qualify as a QDRO, because there was no ambiguity as to how to dispense the proceeds of the ERISA plan. See id. at 1084. In that case, the divorce decree simply referred to the plan at issue as “the life insurance which is presently carried through his/her employer.” Id. at 1081.
In so holding, the court stated:
It is asking too much of domestic relations lawyers and judges to expect them to dot every i and cross every t in formulating divorce decrees that have ERISA implications. Ideally, every domestic relations lawyer should be conversant with ERISA, but it is unrealistic to expect all of them to be. We do not think Congress meant to ask the impossible, not the literally, but the humanly, impossible, or to make a suit for legal malpractice the sole recourse of an ERISA beneficiary harmed by a lawyer’s failure to navigate the treacherous
Id. at 1085.
Like the divorce decree in Wheaton and Marsh, the Marital Dissolution Order in the present case “clearly contains the information specified in the statute that a plan administrator would need to make an informed decision.” Id. at 1416. Both Nielsen and Carpenter were aware of the information needed for the proper allocation of the pension benefits. Thus, the evil that QDRO’s seek to remedy — “litigation-fomenting ambiguities as to who the beneficiaries designated by a divorce decree are” — is absent in this case. See id. at 1084 (emphasis added).
In questioning the holding8 in Wheaton, the dissent states that it is “persuaded by the careful discussion and analysis of Wheaton offered by the Tenth Circuit in Hawkins v. Commissioner of Internal Revenue, 86 F.3d 982 (10th Cir.1996).” A more careful reading of Hawkins, however, should have persuaded the dissent that Hawkins actually militates in favor of our interpretation of ERISA’s specificity requirements for a valid QDRO.9
[1155]*1155As the dissent correctly points out, the Tenth Circuit in Hawkins disagreed with the Seventh Circuit — as do we — to the extent that the decision in Wheaton “seems to suggest[ ] eliminating [ERISA’s QDRO specificity requirements] altogether in some cases.” 86 F.3d at 992. The Tenth Circuit was particularly concerned that ERISA’s requirements not “be disregarded in favor of conducting [an] ad hoc subjective inquiry” into “whether the plan administrator was aware of the parties’ ‘true’ intentions.” Id. Nevertheless, the Tenth Circuit in Hawkins recognized that “the ‘primary focus’ of the QDRO exception [is] to allow alienation of ‘pension plan benefits when spouses [seek] enforcement of domestic support orders.’ ” Id. at 988 (quoting Mackey v. Lanier Collection Agency & Serv., Inc., 486 U.S. 825, 838-39, 108 S.Ct. 2182, 100 L.Ed.2d 836 (1988)). Thus, the Tenth Circuit rejected an “unduly narrow” reading of the specificity requirements for QDROs,10 noting that such a reading “has the potential to frustrate this important congressional purpose by making it unreasonably difficult for domestic relations orders to qualify as QDROs.” Id. at 991 (emphasis added). Instead, the Tenth Circuit stated that precluding a plan participant’s spouse or child “from receiving intended domestic support payments simply because the particular divorce decree failed to track the language of the statute even though the criteria of the statute was satisfied in substance ” was an “undesirable result” that Congress did not intend. Id. (citing with approval Wheaton, 42 F.3d at 1085). We agree.
In applying these principles to the marital settlement agreement incorporated into the divorce decree at issue in Hawkins, the Tenth Circuit held that the divorce decree “clearly specifies the necessary facts” required by law to constitute a valid QDRO, id. at 993-94, despite deficiencies that the dissent suggests should be fatal. The agreement in Hawkins provided that the ex-spouse
is to receive “[c]ash of One Million Dollars ... from Husband’s share of the Arthur C. Hawkins, D.D.S. Pension Plan,” and that Arthur “shall immediately allow [Glenda] to take possession of the property transferred [to her] by this Agreement.”
Id. at 992 (quoting the agreement). Like the Marital Dissolution Order here, the Hawkins decree failed to provide the “current mailing addresses” of the participant and the alternate payee (let alone their zip code, on which the dissent places much emphasis) or to spell out in detail “the number of payments or period to which the order applies.” It also provided for the participant to pay the ex-spouse her share in his pension, not the plan itself. Nevertheless, the Tenth Circuit held the decree to be a valid QDRO. See id. at 990-93.
Accordingly, in light Hawkins, Marsh, and Wheaton, it is clear that the Marital Dissolution Order in this case constitutes a valid QDRO as a matter of law, which is binding on Thorpe Holding and its ERISA Plan. On this basis, we conclude that Stewart has standing to bring this action to enforce her rights as an alternate payee under ERISA.
IV.
STEWART’S ALTERNATE BASIS FOR STANDING
Even assuming that the Marital Dissolution Order does not qualify as a QDRO, Stewart still has standing to bring this action under the unique facts of this case because Nielsen, Carpenter, and Thorpe Holding, by failing to meet their [1156]*1156fiduciary duties under ERISA, denied her the opportunity to obtain a valid QDRO and protect her rights to and community property interest in Nielsen’s interest in the ERISA Plan. We have held that a state court domestic relations order that distributes the community property share of an ERISA pension plan to an ex-spouse gives that ex-spouse “the right to obtain a proper QDRO.” Gendreau v. Gendreau, 122 F.3d 815, 818 (9th Cir.1997) (holding that an ex-spouse’s community property interest in her husband’s ERISA pension plan “was established under state law at the time of the divorce decree” and that her husband could not defeat her “right to obtain a proper QDRO” and be paid her community property share merely by declaring bankruptcy before she obtained a proper QDRO). Moreover, ERISA assigns to plan administrators the fiduciary duty to ensure that an alternate payee’s rights are protected. Accordingly, all ERISA plans must establish reasonable, written procedures to determine the qualified status of a domestic relations order, to communicate those procedures to alternate payees, and to administer the distribution of benefits under such qualified orders. See 29 U.S.C. § 1056(d)(3)(G).
Specifically, upon receipt of “any domestic relations order” — such as the Marital Dissolution Order in this case — a plan administrator must “promptly notify the participant and any other alternate payee of the receipt of such order” and advise them of “the plan’s procedures for determining” whether the order is a QDRO. 29 U.S.C. § 1056(d)(3)(G)(i) (emphasis added). “[W]ithin a reasonable time after receipt of such order, the plan administrator shall determine whether such order is a [QDRO] and notify the participant and each alternate payee of [its] determination.” 29 U.S.C. § 1056(d)(3)(G)(ii). Moreover, while the order’s status as a QDRO is being determined, the plan administrator is required to hold and separately account for amounts that would be payable to the alternate payee if and when the order is determined to be a QDRO. See 29 U.S.C. § 1056(d)(3)(H)(i).11 Should the plan administrator determine that an order does not qualify as a QDRO, the beneficiary or alternate payee may appeal the plan administrator’s decision to a “court of competent jurisdiction ” under 29 U.S.C. § 1056(d)(3)(H)(i) (emphasis added).
In the present case, according to the Summary Plan Description of the Thorpe Holding Company Profit Sharing Plan, Thorpe Holding Company appointed a “Committee” as the plan administrator with the discretionary authority to “determine when and how to pay a Participant his or her benefits under the Plan” and to “interpret[ ] the Plan documents and adopt[ ] appropriate rules for administering the Plan.” And defendants Nielsen and Carpenter were two of four trustees designated as Committee members. Under ERISA, Thorpe Holding Company’s Committee is a “fiduciary” of the ERISA Plan because it exercises “discretionary authority or discretionary control respecting management of such plan ... [and] discretionary authority or discretionary responsibility in the administration of such plan.” 29 U.S.C. § 1002(21)(A)(i), (iii). Moreover, where, as here, a committee or entity is named as the plan fiduciary, the corporate officers or trustees who carry out the fiduciary functions are themselves fiduciaries and cannot be shielded from liability by the company. See Kayes v. Pacific Lumber Co., 51 F.3d 1449, 1459-61 (9th Cir. 1995) (rejecting the Third Circuit’s ap[1157]*1157proach that relieves individual officers or directors of liability as fiduciaries unless the entity that is named as the plan’s fiduciary officially delegates its fiduciary duties to them).
Thus Nielsen was not only Stewart’s ex-husband, he was a trustee and one of four Committee members serving as an administrator of the ERISA Plan when he executed and received as acceptable the Marital Settlement Agreement incorporated into the Marital Dissolution Order. Nielsen therefore had notice of the Order and a fiduciary duty to comply with the statutory provisions outlined above. See 29 U.S.C. § 1104 (setting forth the fiduciary duties of ERISA plan administrators, which include the duty to act “with the care, skill, prudence, and diligence under the circumstances then prevailing that a prudent man acting in like capacity and familiar with such matters would use ... ”). Furthermore, Carpenter and the other Committee members appointed to administrate the ERISA Plan, as Nielsen’s co-fiduciaries, also had notice of the Order by virtue of Nielsen’s notice. See 29 U.S.C. § 1105 (setting forth the circumstances giving rise to liability for breach by a co-fiduciary). And they had the affirmative duty to prevent Nielsen from breaching’ his fiduciary duties. See, e.g., Donovan v. Walton, 609 F.Supp. 1221, 1231 (S.D.Fla.1985) (holding that 29 U.S.C. § 1105(a) effectively imposes on every ERISA fiduciary an affirmative duty to prevent other fiduciaries from breaching their duties for which they are jointly and severally liable),12 aff'd. sub nom. Brock v. Walton, 794 F.2d 586 (11th Cir.1986).
The record strongly suggests that neither Nielsen, Carpenter, nor any of the other Committee members serving as plan administrators in this case performed their fiduciary duties pursuant to 29 U.S.C. § 1056(d)(3)(G), (H). They apparently never informed Stewart of the Plan’s written procedures for determining whether the Marital Dissolution Order was a QDRO, let alone the implicit decision to declare it not to be a QDRO.13 By doing so, defendants denied Stewart the opportunity “to obtain a valid QDRO” as required by Gendreau and thwarted her right to appeal that determination to a “court of competent of jurisdiction” as required by 29 U.S.C. § 1056(d)(3)(H)®. Stewart therefore has standing to bring this action in district court as a “court of competent jurisdiction,” to protect her right to obtain a valid QDRO.14

CONCLUSION
We held in Gendreau that
[the wife’s] interests in the pension plan (or, at a minimum, her right to obtain a QDRO which would in turn give her an interest in the plan) was established under state law at the time of the divorce decree.... Whether or not [the wife’s] domestic relations order, as issued, was a QDRO is irrelevant: The QDRO provisions do not suggest that [the wife] has no interest in the plans until she obtains a QDRO, they merely prevent her from enforcing her interest until the QDRO is obtained.
122 F.3d at 818. Stewart’s community property interest in Nielsen’s pension plan was established under state law by the Marital Dissolution Order. Stewart’s ability to enforce that interest against the Plan depended on her ability to present a valid QDRO. Nielsen, Carpenter, and Thorpe Holding had the fiduciary duty under ERISA to preserve Stewart’s “right to obtain a valid QDRO.” If they determined that the Marital Dissolution Order was not a valid QDRO, they had the fiduciary duty to afford her the opportunity to make it so or to appeal their decision to a “court of competent jurisdiction.” The fact that Nielsen, Carpenter, and Thorpe Holding failed in all these respects does not defeat Stewart’s rights under 29 U.S.C. § 1056(d)(3)(H)(i) and related subsections. Therefore, Stewart has standing to bring this matter before the district court.
Accordingly, we REVERSE the district court’s grant of summary judgment in favor of defendants and REMAND to the district court with instructions to enter an order finding that the Marital Dissolution Order is a valid QDRO and therefore Stewart has standing to bring this action.
REVERSED and REMANDED.
