In Georgia litigation between the estate of a Kentucky resident and an uninsured resident of Illinois, the jury apportioned fault 60% against the Kentucky decedent and 40% against the uninsured Illinois driver. Under the modified comparative fault scheme in Georgia, a finding of fault of 50% or more against a plaintiff precludes recovery. The issue in this declaratory judgment action between the estate of the decedent and its uninsured motorist insurance carrier is whether the outcome of the Georgia litigation precludes recovery under the uninsured motorist policy.
On January 26, 1993, Mikeal Preston and his brother, both Kentucky residents, were traveling on Interstate 75 for their employer, R & P Industrial Chimney, a Kentucky corporation. Near Valdosta, Georgia, their truck left the road, flipped over, and stopped in the median. Neither Mikeal nor his brother was injured at that time. The equipment they were carrying was scattered across the highway, and Mi-keal began to collect it. "While engaged in this activity, he was hit and killed by a car driven by Clifford West, an uninsured motorist from Illinois. Mikeal had a personal automobile insurance policy with State Automobile Insurance Company. His employer, R & P, was insured by United States Fidelity and Guaranty Company.1
Clara J. Preston, individually and as ad-ministratrix of Mikeal’s estate, brought civil litigation against Clifford D. West in the United States District Court for the Middle District of Georgia. Unlike Kentucky, which has a pure comparative fault statute,2 Georgia has a modified comparative fault scheme under which a plaintiff whose negligence is greater than that of the defendant may not recover damages.3 As such, upon the Georgia jury’s determination that Preston was 60% at fault and West was 40% at fault, the Georgia court entered judgment for West. Thus, Preston’s estate obtained no recovery from West despite the jury’s finding that he was partially at fault.
On January 3, 1994, USF & G sought a declaratory judgment in the Fayette Circuit Court to determine the rights, obligations, and liabilities it had to the Preston estate. This case was held in abeyance pending the outcome of the Georgia trial, after which the Fayette Circuit Court denied the estate any UM benefits and dismissed the case with prejudice. In reaching this result, the trial court reasoned that to allow the Preston estate “to proceed in Kentucky on the issue of the amount of damages when Georgia law held there were no damages, would deny full faith and credit to the Georgia judgment.”
The Court of Appeals vacated and remanded. Rejecting the contention that granting full faith and credit to the Georgia judgment precluded recovery against USF & G and observing that it was peculiar aspects of Georgia law that prevented recovery, the Court of Appeals held that *147only the issue of relative fault was barred from subsequent litigation.
The Court of Appeals believed contract interpretation to be controlling of this litigation. In three separate opinions from the three-judge panel, each judge expressed a different interpretation of the critical provision of the USF & G insurance contract. That provision states:
We will pay all sums the insured is legally entitled to recover as compensatory damages from the owner or driver of an uninsured motor vehicle.
(emphasis added).
The lead Court of Appeals opinion held that the phrase “legally entitled to recover” means that the insured must prove two “essential facts”: (1) the fault of the uninsured motorist, and (2) the extent of damages caused by the uninsured motorist. Since the issue of fault had been litigated in Georgia, that issue was barred from re-litigation by principles of collateral estop-pel. The extent of damages, however, was not resolved by the Georgia court because Georgia’s comparative fault law prevented the estate from receiving damages. Thus, the Preston estate was held entitled to prove in the declaratory judgment action the extent of damages caused by West, with USF & G being obligated to pay 40% of those damages as UM benefits.
A concurring opinion was based upon the doctrine of “reasonable expectations” and ambiguity.4 That opinion stated that the law of Kentucky should apply since the insurance contract was made in Kentucky and the decedent was a resident of Kentucky. Under the doctrine of reasonable expectations, followed in Kentucky, when the language of an insurance policy is ambiguous, the ambiguity must be construed in favor of the insured and benefits granted in accordance with the reasonable expectations of the parties. Thus, UM benefits should be available to the estate.
The dissenting opinion adamantly rejected this view, stating that the doctrine of reasonable expectations did not apply because the critical phrase, “legally entitled to recover,” was thoroughly unambiguous. Since the estate was not “legally entitled to recover” anything from the uninsured tortfeasor according to the Georgia judgment, the dissent concluded, the estate had no right to recover anything under the policy.
As demonstrated by the tripartite Court of Appeals opinion, a variety of interpretations is invited by the contractual language, “legally entitled to recover.” The decedent’s estate urges this Court to adopt the “essential facts” approach described by the lead opinion of the Court of Appeals. As set forth hereinabove, this approach requires an insured to prove (1) the fault of the uninsured motorist, and (2) the extent of damages caused by the uninsured motorist. We observe that this approach has the advantages of uniformity of application regardless of the jurisdiction in which the related civil action may have been brought, and of allowing the parties to know at the time of issuance of the insurance contract what benefits are available and required. This approach also ensures that the public policy of Kentucky with regard to UM insurance coverage is not made subservient to peculiar rules of law in other jurisdictions.
USF & G contends that there is no ambiguity in the policy language, and that the estate may not recover UM benefits because the estate is not legally entitled to recover damages under the Georgia judgment. While we see this facile argument as not unappealing, it is undesirable because of its effect on Kentucky public policy and its inconsistency of application. Such an interpretation would cause a Kentucky insurance policy to yield a variety of inconsistent results depending upon the laws of other jurisdictions. Laws unique to other jurisdictions, e.g., regarding statutes of limitations, interspousal immunity, worker’s compensation, and comparative *148or contributory negligence, should not bind and define the public policy of Kentucky. Under the USF & G argument, there could be many different interpretations of the same Kentucky insurance policy provision. Such multiple and inconsistent results would defeat the public policy underlying Kentucky UM insurance: the compensation of people who are injured by the negligence of uninsured motorists.
It should not be overlooked that the public policies of Georgia and Kentucky regarding recovery in negligence cases differ greatly. In Georgia, one who is one-half or more at fault for his own injuries may not recover damages. In concept, this is similar to contributory negligence which holds that one even only slightly at fault may not recover. In contrast, Kentucky judicially adopted pure comparative negligence in Hilen v. Hays,5 and later a statute was enacted, KRS 411.182, which likewise adopted pure comparative negligence. This doctrine provides that an injured person may recover against one who is negligent even if the injured person was partly responsible for the injury. Of course, the amount of recovery is reduced in proportion to the injured party’s fault. In the last two decades, both the Supreme Court and the General Assembly have unmistakably articulated the public policy of this Commonwealth with respect to recovery in negligence cases. To embrace the view of USF & G would be to renounce this overwhelming policy.
Based upon these considerations, we believe the “essential facts” view advocated by the estate is the better approach. This approach is consistent with firmly established Kentucky law. In Puckett v. Liberty Mutual Ins. Co.,6 this Court held that the right to recover UM benefits is not conditioned upon entry of judgment against the uninsured tortfeasor. We reiterated this fundamental principle in Coots v. Allstate,7 stating that coverage for damages caused by an uninsured motorist “exists without regard to whether the obligation of the tortfeasor can be reduced to judgment.” Thus, a claimant may recover UM benefits in a hit-and-run accident in which there would be no judgment and no recovery. The Court in Coots also explained that a claimant must prove the “essential facts” to recover UM benefits from an insurer .8 These essential facts are that “the offending motorist is a tortfea-sor,” and “the amount of damages caused by the offending motorist.”9 Cases from numerous foreign jurisdictions support the “essential facts” approach followed here.10
The “essential facts” approach is also consistent with the doctrine of reasonable expectations. Under this principle of contract interpretation, when the language *149of an insurance policy is reasonably susceptible to more than one interpretation, the ambiguity must be construed in favor of the insured.11 Certainly, when contracting for UM coverage for its employees and paying the premiums for this coverage, the decedent’s employer intended and could reasonably have expected UM coverage to be provided when that employee was injured by a negligent motorist without automobile liability insurance.
The result achieved herein does not contravene the principle of full faith and credit. By this principle, a “judgment conclusive between the parties in the state in which it is rendered is equally conclusive in other states.”12 Here, the Georgia judgment in favor of the uninsured motorist, West, will not be offended by the estate’s recovery of benefits under the unrelated UM insurance contract. USF & G’s liability is not vicarious or “purely derivative,” 13 but is based instead upon an independent contract that could be enforced even if the tortfeasor had been unidentified. Only the apportionment of fault was litigated in the Georgia court, and only that issue is barred from re-litigation. The extent of damages arising from West’s tortious conduct was not decided by the Georgia jury. Thus, the Preston estate is entitled to prove the total amount of damages in the declaratory judgment action, and USF & G will be liable for 40% of those damages not to exceed the policy limits.
For the foregoing reasons, the judgment of the Court of Appeals is affirmed, and the case is remanded to the Fayette Circuit Court for action in conformity with this opinion.
