*713 OPINION
In 1995, Elizabeth Rouse successfully petitioned Michigan’s Macomb County Circuit Court to retroactively modify her 1984 divorce settlement via a domestic relations order. The order gave Rouse survivor-ship-benefits in her deceased ex-husband’s pension. It also impacted the Daimler-Chrysler Corporation UAW Non-Contributory Plan’s (“the Plan”) obligations under the Employee Retirement Income Security Act of 1974 (“ERISA”).
The Plan removed Rouse’s case to federal court on the basis of federal-question jurisdiction. It contested the domestic relations order’s validity, claiming that the state court issued it pursuant to a sham hearing. The district court, through Judge Denise Page Hood, held that this was an issue that should be decided by the state court. Thus, the district court dismissed the case so that the parties could refile it in state court.
Two years later, Rouse filed a Motion for Rule to Show Cause in an effort to require the Plan to pay her survivorship-benefits claim. The Plan again removed the case to federal court. This time the Plan argued that the domestic relations order was invalid under ERISA.
Judge Hood recused herself and the case was assigned to Judge Borman. Judge Borman reviewed Judge Hood’s order and concluded that it required the parties to resolve all issues about the domestic relations order’s validity in state court. He held that Judge Hood’s order was law of the case and stayed the suit pending a state court’s decision about the order.
Judge Borman also held that “comity and collegiality between coordinate courts,” as well as ERISA’s statutory scheme, required that the domestic relations order’s validity be decided in state court. He denied the Plan’s motion for entry of judgment and stayed all proceedings pending the state court’s decision.
For the following reasons, we REVERSE the district court’s judgment.
BACKGROUND
Elizabeth Rouse was married to Chrysler Corporation employee Kenneth C. Rouse for approximately 27 years. The Rouses divorced on April 11, 1984, and entered into a property settlement before the Macomb County Circuit Court. The settlement agreement stated that:
the Defendant [Elizabeth Rouse] is awarded one-half of any pension payment paid to the Plaintiff [Kenneth Rouse] by Chrysler Corporation prior to the Plaintiff attaining the age of sixty two (62) years. After Plaintiff has attained the age of sixty two (62) years, Defendant is awarded the sum of TWO HUNDRED THIRTY THREE AND 62 ($233.62) DOLLARS per month of any pension payments paid to the Plaintiff by Chrysler Corporation. In the event of Plaintiffs death, Defendant is awarded any survivors pension payments payable by Chrysler Corporation; however, Plaintiff shall not be obligated to provide for any such survivors payments.
When Kenneth Rouse died of cancer in April 1994, Mrs. Rouse sent a letter to the Chrysler UAW Pension Board of Administration (“the Board”) asking it to provide her with surviving spouse benefits from her ex-husband’s pension. Chrysler’s pension analyst wrote back to Mrs. Rouse and informed her that she was ineligible for those benefits. The pension analyst stated that although Mr. Rouse was an active participant in the Chrysler UAW Non Contributory Pension Plan, the Plan did not provide for automatic payment of sur *714 viving spouse benefits. The analyst further noted that the divorce decree upon which Mrs. Rouse based her claim did not expressly obligate Mr. Rouse to provide for survivor payments.
Since Mr. Rouse did not assign survivor benefits to Mrs. Rouse in the settlement agreement, and the Plan did not automatically provide them, Chrysler informed Mrs. Rouse that she would need to get a Qualified Domestic Relations Order (“QDRO”) to receive surviving-spouse benefits. Mrs. Rouse notified Chrysler that she intended to seek a QDRO and she sent the Board a proposed QDRO. Board member Ronald Gurdak approved the proposed QDRO as to its form, but would not approve its content. Mrs. Rouse then filed suit in county court in an effort to get a domestic relations order (“DRO”) that qualified under ERISA. The county court held a hearing, but the Plan did not appear at the hearing or file an opposition brief. Accordingly, the county court issued Mrs. Rouse a DRO and forwarded a copy to the Board.
Armed with the Macomb County Circuit Court’s July 5, 1995, Order, Mrs. Rouse again requested the Board to approve her request for pension benefits. On September 22, 1995, the Board denied her request. It stated several reasons for the decision. Among them, the Board asserted that the state court’s DRO did not qualify under ERISA because:
a) The pension agreement between Chrysler and Mr. Rouse was not obligated to provide benefits to Plaintiff at his death;
b) There was no indication of Mr. Rouse’s intent to change division of property status at time of divorce;
c) The new decree was entered 11 years after divorce and 10 years after enactment of [the Retirement Equity Act of 1984, P.L. 98-397];
d)The Domestic Relations Order was submitted to the court after Mr. Rouse’s death.
In 1996, Mrs. Rouse moved the district court for summary judgment, arguing that the Board did not have authority to disregard the state court’s DRO. The Plan also moved for summary judgment, asserting that the 1984 divorce decree did not obligate Mr. Rouse to pay Mrs. Rouse surviv- or benefits and that the DRO was the invalid result of a sham state court proceeding. Judge Hood denied both parties’ motions, holding that the propriety of the Plan’s denial could not be assessed until the state court interpreted the divorce decree and the DRO. Judge Hood dismissed the case and it remained idle for two years until Mrs. Rouse filed a Motion for Order to Show Cause in state court to obtain survivor benefits.
Since Mrs. Rouse’s benefit claim implicated ERISA, the Plan removed the case to district court pursuant to 28 U.S.C. § 1331. Judge Hood recused herself and the case was assigned to Judge Paul Bor-man. The Plan moved for an entry of judgment and Judge Borman denied the motion. Judge Borman held that the law-of-the-case doctrine required the court to follow Judge Hood’s previous order. Judge Borman also held that “comity and collegiality between coordinate courts,” as well as ERISA’s statutory scheme, required that the DRO’s validity be decided in state court. He stayed the case pending the state court’s decision about the divorce decree and the DRO’s validity. The Plan timely appealed the district court’s judgment.
DISCUSSION
Three issues comprise this appeal: the application of the law-of-the-case doctrine; the application of
Burford
abstention
(see
*715
Burford v. Sun Oil Co.,
A. Law-of-the-case Doctrine
We use an abuse of discretion standard when reviewing a lower court’s application of the law-of-the-case doctrine.
See Pacific Employers Ins. Co. v. Sav-a-Lot of Winchester,
The Plan asserts that the district court improperly applied the law-of-the-case doctrine to prevent consideration of the DRO’s validity under ERISA. According to the Plan, Judge Hood’s 1998 Order and Opinion never made any findings with respect to this aspect of the DRO’s validity. Judge Hood, the Plan contends, only considered whether the DRO was issued following a sham hearing in the state court. Since Judge Hood limited her Order and Opinion to the sham-hearing issue, the Plan argued that Judge Borman could consider the separate matter of whether the order was valid under ERISA. Judge Borman disagreed. In his estimation, Judge Hood’s Order and Opinion found that the DRO’s validity should be decided by the state court and this was law of the case.
A careful review of Judge Hood’s 1998 Order and Opinion shows that the only issue she decided with respect to the DRO’s validity was whether the order was issued pursuant to a sham proceeding. Moreover, she expressly stated that “[wjhether the QDRO met the requirements of ERISA is not in dispute, or at the very least this issue has not been addressed by either party.” Because Judge Hood did not make a finding about the DRO’s validity under ERISA, it was an abuse of discretion for Judge Borman to hold that the law-of-the-case doctrine barred him from considering this issue.
B. Abstention
This Court reviews abstention decisions de novo.
See Heitmanis v. Austin, 899
F.2d 521, 527 (6th Cir.1990) (citing
Litteral v. Bach,
The district court apparently dismissed this case pursuant to the
Burford
abstention doctrine.
2
See Burford v. Sun
*716
Oil Co.,
The Bmford abstention doctrine is inapplicable here for several reasons. First, there is no state administrative agency involved in the dispute. Second, there is no difficult question of state law whose importance transcends the result of this case, or any basis for concluding that federal review of this matter would be disruptive of Michigan’s domestic relations policies. The question before the district court was whether the DRO satisfied § 1056 of ERISA. That question is strictly federal. Since federal review of the DRO was limited to determining whether the DRO created any obligations under ERISA—a federal statute—the district court’s review did not require it to meddle in state domestic relations law or interfere with state domestic relations policies.
Moreover, the Supreme Court has stated that when the status of a domestic relationship has been determined as a matter of state law—upon the entry of a divorce, settlement agreement, etc.—and has no bearing on the underlying claim, “we have no difficulty concluding that
Burford
abstention is inappropriate.”
See Ankenbrandt v. Richards,
C. Collateral Attack
Finally, Mrs. Rouse contends that the Plan’s Motion for Entry of Judgment is an impermissible collateral attack on Judge Hood’s 1998 Order and Opinion. The record does not support this contention.
When Judge Hood dismissed Mrs. Rouse’s and the Plan’s cross-motions for summary judgment in 1998, she did so to allow the state court' the opportunity to determine whether or not the DRO was issued pursuant to a sham hearing. Her Order and Opinion did not address whether the DRO was valid under ERISA, and that was the primary issue in the Plan’s subsequent Motion for Entry of Judgment. Since the issues Judge Hood considered were not the same issues in the Plan’s Motion for Entry of Judgment, the Motion *717 for Entry of Judgment cannot be considered a collateral attack.
CONCLUSION
For the foregoing reasons, the judgment of the district court is REVERSED. The case is REMANDED for further consideration consistent with this opinion.
Notes
. The Plan raises the district court's jurisdiction as a fourth issue for appeal. The Plan contends that the district court had jurisdiction to hear the ERISA issue raised in the Motion for Entry of Judgment. Since no one disputes this and it is clear that the district court had jurisdiction pursuant to 28 U.S.C. § 1331, we will not further discuss the issue.
. The district court did not specifically refer to Burford. However, its comment about "re *716 spect for state domestic relations law” indicates that it relied on this abstention doctrine.
