MARCIA S. KRIEGER, Chief District Judge.
A civil action is removable only if the plaintiff could have originally brought the action in federal court. 28 U.S.C. § 1441(a). The Court is required to remand "[i]f at any time before final judgment it appears that the district court lacks subject matter jurisdiction." 28 U.S.C. § 1447(c). Diversity jurisdiction under 28 U.S.C. § 1332 exists when the case involves a dispute between citizens of different states, and the amount in controversy exceeds $75,000. 28 U.S.C. § 1332(a)(1). As the party invoking the federal court's jurisdiction, the defendant bears the burden of establishing that the requirements for the exercise of diversity jurisdiction are met. See Huffman v. Saul Holdings Ltd. P'ship, 194 F.3d 1072, 1079 (10th Cir. 1999).
The amount in controversy is ordinarily determined by the allegations of the complaint, or, where they are not dispositive, by the allegations in the notice of removal. The burden is on the party requesting removal to set forth, in the notice of removal itself, the underlying facts supporting the assertion that the amount in controversy exceeds the jurisdictional minimum. Laughlin v. Kmart Corp., 50 F.3d 871, 873 (10th Cir. 1995); Martin v. Franklin Capital Corp., 251 F.3d 1284, 1290 (10th Cir. 2001). A defendant seeking removal may rely on an estimate of potential damages from the allegations in the complaint. McPhail v. Deere & Co., 529 F.3d 947, 955 (10th Cir. 2008). Further, the Tenth Circuit has held that "[a] complaint that presents a combination of facts and theories of recovery that may support a claim in excess of $75,000 can support removal." Id.
Here, neither the Complaint
Disregarding the Civil Cover Sheet, the Defendant relies on the alleged injuries and theories of recovery presented in the Complaint to support its assertions about the amount in controversy. The Complaint alleges that Ms. Milton was involved in a car accident with an underinsured motorist, and as a result, she suffered "pain, suffering, loss of enjoyment of life, and permanent disfigurement, impairment and/or disability." The Complaint seeks recovery for all damages, as well as for "two times the covered under-insured motorist benefits plus reasonable attorney fees" for alleged violation of C.R.S. § 10-3-1116. However, the Complaint does not present any underlying facts as to the specific nature or cost of Ms. Milton's alleged injuries, such that the Defendant could reasonably estimate the amount in controversy. As additional facts, the Defendant asserts that (1) Ms. Milton's insurance policy included an underinsured motorist benefit with limits of $100,000 per person, or $300,000 per accident, and (2) Ms. Milton received a $25,000 settlement from the alleged tortfeasor responsible for her injuries. The Defendant alleges that Ms. Milton's medical bills exceed the $25,000 she already received, and that she sustained injuries to her wrist, neck, back and knee. The Defendant makes no allegation, however, as to an estimated amount of Ms. Milton's excess medical bills, or the amount of benefits she claims she is entitled to. Although one might assume that Ms. Milton will seek the maximum amount permitted under her policy benefit, that sum is nevertheless limited by her loss. The Court finds that there are insufficient factual allegations with regard to Ms. Milton's loss to calculate the amount in controversy. Accordingly, the Court lacks subject matter jurisdiction over this action, and the case must be remanded to state court.
