MEMORANDUM AND ORDER
Pending is Defendant/Cross-Claimant the United States of America’s Motion for Summary Judgment (Document No. 46). After carefully considering the motion, response, reply and the applicable law, the Court concludes that the United States’s motion should be granted.
I. Background
This is a tax liability case previously described in the Court’s Memorandum and Order entered May 14, 2003 (Document No. 34). The United States (“Government”) moves for summary judgment on its amended cross-claim against Dana L. Monford, as Temporary Administrator of the Estate of Leslie H. Williams, Jr. (“Monford”), which cross-claim seeks an order that the Estate of Leslie H. Williams, Jr. (“Estate”) is indebted to the United States for $543,463.29 in federal income taxes, penalties, and interest owed for the tax years ending 1992, 1997, 1999, 2000, and 2001, plus statutory additions provided by law. 1 Monford contends that the Court lacks jurisdiction to enter such an order.
II. Jurisdiction
A. Standard of Review
Although Monford does not formally move to dismiss the Government’s amended cross-claim, she asserts as her only defense to the Government’s motion for summary judgment that the Court lacks subject matter jurisdiction.
The burden of establishing subject matter jurisdiction is on the party seeking to invoke it.
St. Paul Reins. Co., Ltd. v. Greenberg,
*722 B. Discussion
As stated' above, the Government’s amended cross-claim seeks an order adjudging liability for certain federal income taxes, penalties, and interest owed for the tax years ending 1992, 1997, 1999, 2000, and 2001, plus statutory additions provided by law. See Document No. 42; No. 18. The Government asserts that this Court has jurisdiction under 26 U.S.C. § 7402(a) (“The district courts ... shall have such jurisdiction ... to render such judgments and decrees as may be necessary or appropriate for the enforcement of the internal revenue laws.”), 28 U.S.C. § 1340 (“The district courts shall have original jurisdiction of any civil action arising under any Act of Congress providing for internal revenue, ... ”), and 28 U.S.C. § 1345. In its Memorandum and Order enter May 14, 2003, the Court held that subject matter jurisdiction existed over the Government’s cross-claim under 26 U.S.C. § 7402(a) and 28 U.S.C. § 1340. See Document No. 34, at 10 n. 2. The Government has established that the Court does have jurisdiction over its claim unless Monford’s new argument has merit. Monford argues that the Court now lacks jurisdiction over the Government’s amended cross-claim because the Government subsequently filed its claim for taxes in probate court.
It was after the issuance of the Court’s Memorandum and Order entered May 14, 2003 — and after the Government’s filing of its amended cross-claim — that the Government filed its claim for taxes, penalties, interest, and statutory additions in Probate Court No. 1 of Harris County, Texas (“Probate Court”). The Government’s authenticated claim against the Estate in the Probate Court was for $543,583.44 in unpaid taxes, penalties, and interest for the tax years 1992, 1997, 1999, 2000, 2001, and 2002. See Document No. 50 ex. A. 2 Mon-ford allowed the claim and the Probate Court approved it as a class three claim. See id. exs. A, B. The Government then amended its claim to include interest and statutory additions dating from March 15, 2004. See id. ex. C. Monford also allowed the amended claim. See id. The Court takes judicial notice (1) that on May 10, 2004, the Probate Court approved the Government’s amended claim, although without classifying it; and (2) that on May 20, 2004, the Probate Court authorized Mon-ford to pay $83,949.59 to the Government as a partial credit on the amended claim.
Because the Government filed its tax claim against the Estate in Probate Court, Monford argues that action on the Government’s cross-claim in this Court would now interfere with proceedings in the Probate Court. Such interference, Monford contends, precludes the exercise of federal jurisdiction.
“[A] federal court has no jurisdiction to probate a will or administer an estate.”
Markham v. Allen,
[Fjederal courts of equity have jurisdiction to entertain suits “in favor of creditors, legatees, and heirs” and other claimants against a decedent’s estate “to establish their claims” so long as the federal court does not interfere with the probate proceedings or assume general jurisdiction of the probate or control of the property in the custody of the state court.
Markham,
The Government’s Motion for Summary Judgment on its amended cross-claim seeks an order that “Dana L. Monford, as Temporary Administrator of the Estate [ ] of Leslie H. Williams, Jr. is liable to the United States for the federal income (Form 1040) tax for the tax years ending 1992, 1997, 1999, 2000, and 2001 in the amount of $543,463.29, plus interest and statutory additions.”
See
Document No. 46. Generally, “a determination of the validity and amount of the tax claims against [a] decedent’s estate” does not “in any way interfere with the orderly process of the administration of the estate in the Probate Court, nor does it attempt to deal with the
res
of the estate or its orderly distribution.”
United States v. Estate of Slate,
Relying on Slate and Vanderwater, Monford argues that “[t]he validity and amount of [the Government’s] Claim and Amended Claim has [sic] essentially been adjudicated when Monford approved them,” and that the Court therefore lacks jurisdiction to make such a determination. Document No. 50, at 6. Neither Slate nor Vanderwater, however, stands for the proposition that a federal court lacks jurisdiction over a party’s claim when a probate court has adjudicated the merits of a similar claim. In each case, with the dictum in Slate and the holding in Vanderwater, the implication is that principles of res judicata and comity may bar in federal court the re-litigation of a claim already adjudicated in probate court. These cases do not hold, however, that federal court is without subject matter jurisdiction, which in this case is plainly conferred by 26 U.S.C. § 7402(a) and 28 U.S.C. § 1340.
The probate limitation on federal jurisdiction stated in
Markham
does not foreclose a federal court’s “jurisdiction to adjudicate rights in such property where the final judgment does not undertake to interfere with the state court’s possession save to the extent the state court is bound by the judgment to recognize the right adjudicated by the federal court.”
Markham,
III. Summary Judgment
A. Standard of Review
Rule 56(c) provides that summary judgment “shall be rendered forthwith if the pleadings, depositions, answers to interrogatories, and admissions on file, together with the affidavits, if any, show that there is no genuine issue as to any material fact and that the moving party is entitled to a judgment as a matter of law.” FED. R. CIV. P. 56(c). The moving party must “demonstrate the absence of a genuine issue of material fact.”
Celotex Corp. v. Catrett,
Once the movant carries this burden, the burden shifts to the nonmovant to show that summary judgment should not be granted.
See id.
at 2553-54. A party opposing a properly supported motion for summary judgment may not rest upon mere allegations or denials in a pleading, and unsubstantiated assertions that a fact issue exists will not suffice.
See Morris v. Covan World Wide Moving, Inc.,
In considering a motion for summary judgment, the district court must view the evidence through the prism of the substantive evidentiary burden.
See Anderson,
B. Discussion
The uncontroverted summary judgment evidence shows that with respect to the tax years set forth in the amended cross-claim, the Estate is liable for federal income taxes, penalties, and interest totaling, as of March 15, 2004, $543,463.29. See Document No. 48 exs. 1-2.
Aside from challenging jurisdiction, Monford presents no reason why the Court should not grant the Government summary judgment on its amended cross-claim. The Government’s Motion for Summary Judgment is therefore granted.
Monford expresses concern that such a judgment will allow the Government to
*725
interfere with the administration of the Estate by attempting to levy on property within the control of the Probate Court.
See
Document No. 50, at 6. The Court does not anticipate that the Government will improperly interfere in the Probate Court’s administration of the Estate.
See, e.g., United States v. Silverman,
IV. Order
For the reasons set forth, it is hereby
ORDERED that Defendant/Cross-Claimant the United States of America’s Motion for Summary Judgment (Document No. 46) is GRANTED, and it is hereby
ORDERED that Dana L. Monford, as Temporary Administrator of the Estate of Leslie H. Williams, Jr., as of March 15, 2004, is liable to the United States for the federal income (Form 1040) tax for the tax years ending 1992, 1997, 1999, 2000, and 2001 in the amount of $543,463.29, plus interest and statutory additions.
The Clerk will enter a copy of this Order and send a copy to all counsel of record.
Notes
. After the Court issued its Memorandum and Order entered May 14, 2003, the United States amended its cross-claim to include the tax years 1992 and 2001. See Document No. 42. Although the United States asserted both its original and amended cross-claims against Anna Harris Williams as well as the Estate, the United States has since reached an agreed judgment with Anna Harris Williams resolving its claims against her. See Document No. 49.
. The Government's claim in Probate Court was for $120.15 more than the amount of its cross-claim here. This de minimis disparity is not a point of argument between the parties.
