Reversed and remanded by published opinion. Judge WILKINS wrote the opinion, in which Judge TRAXLER and Judge GREGORY joined.
OPINION
William Powell (William) and his wife, Debbie, appeal a district court order granting summary judgment against them in an action brought by Nationwide Mutual Insurance Company (Nationwide) seeking a declaration that an automobile policy it issued to William did not provide underin-sured motorist (“UIM”) coverage. We reverse and remand for further proceedings. 1
I.
Viewing the record in the light most favorable to the Powells, as we must in deciding the appropriateness of granting summary judgment to Nationwide,
see Figgie Int’l, Inc. v. Destileria Serralles, Inc.,
In June 1998, William authorized Debbie to obtain a rate quote and an application from Nationwide for coverage of his two vehicles. Debbie contacted the Nationwide agent from whom she had obtained her own policy and informed the agent that her husband desired liability coverage of $100,000 on his two vehicles and that he wanted “full coverage” as he had with his then-current insurer. Debbie met with the agent’s assistant, Sherry Volz, and at Volz’s direction signed William’s name beside several “X” marks on various forms. One of the signatures was in a space indicating that the insurance applicant (William) did not wish to purchase UIM coverage. Another signature was in a space confirming that the applicant had read the explanation of UIM coverage contained in the form. Debbie did not know what UIM coverage was, nor did Volz explain it to her. Additionally, Volz never asked Debbie whether William had authorized her to apply for insurance or reject UIM coverage on his behalf, and Debbie never told Volz that she was so authorized.
William was displeased when he learned that Debbie had applied for a policy, but when Debbie assured him that the resulting policy would contain the “full coverage” that he desired, he chose not to rescind the application. Accordingly, when Volz contacted him, William told her that he wanted the policy. (Volz did not ask William whether Debbie had been authorized to act on his behalf, nor did she specifically inquire as to whether William desired UIM coverage.) Nationwide subsequently issued the policy with William listed as the named insured and Debbie listed as a driver. The policy included, inter alia, comprehensive, collision, towing, and rental-car reimbursement coverage. Although the policy, which Nationwide sent William, indicated that it did not provide UIM coverage, William never read the policy and continued to believe that UIM coverage was included.
William never rescinded, modified, or canceled the policy, and he paid the premium. Shortly after he had renewed the policy for an additional six months, Debbie was driving one of William’s vehicles when she was involved in an accident caused by another driver and sustained injuries in excess of the other driver’s limits. When she subsequently made a claim under William’s policy, Nationwide made payments for property damage, towing, and automobile rental but denied that the policy provided UIM coverage. 2 Nationwide then instituted this action, and the district court subsequently granted summary judgment to Nationwide.
II.
Because the district court sat in diversity, we must apply South Carolina law and predict how the South Carolina Supreme Court would decide this issue.

See Doe v. Doe,
(1) the insurer’s notification process must be commercially reasonable, whether oral or in writing; (2) the insurer must specify the limits of optional coverage and not merely offer additional coverage in general terms; (3) the insurer must intelligibly advise the insured of the nature of the optional coverage; and (4) the insured must be told that optional coverages are available for an additional premium.
State Farm Mut. Auto. Ins. Co. v. Wannamaker,
A statute apparently passed in response to
Wannamaker
provides guidelines for the forms that insurers must use to offer UIM coverage to “new applicants.” S.C.Code Ann. § 38-77-350(A) (Law.Coop.2002);
see Robb v. Catawba Ins. Co.,
If this form is properly completed and executed by the named insured it is conclusively presumed that there was an informed, knowing selection of coverage and neither the insurance company nor any insurance agent has any liability to the named insured or any other insured under the policy for the insured’s failure to purchase any optional coverage or higher limits.
S.C.Code Ann. § 38-77-350(B) (Law.Coop.2002). However, presentation of a proper UIM coverage rejection form to a named insured’s spouse does not constitute a meaningful offer of UIM coverage if the spouse is not acting as the named insured’s agent.
See Allstate Ins. Co. v. Estate of Hancock,
Before the district court, Nationwide contended that Debbie was acting as William’s agent when she procured the policy and that the presentation of the UIM form to her constituted a meaningful offer of UIM coverage. 4 The district court agreed that an offer of UIM coverage made to a person acting as the named insured’s agent could constitute a meaningful offer of UIM coverage. The court concluded, however, that Nationwide failed to demonstrate as a matter of law that Debbie had either actual or apparent authority to reject UIM coverage on her husband’s behalf. 5
*205 Nationwide also argued that even if Debbie lacked authority to procure the policy on her husband’s behalf, the policy should not be reformed to include UIM coverage because William ratified Debbie’s rejection of UIM coverage by accepting the policy without complaint. The district court adopted this position and granted summary judgment to Nationwide on this basis.
III.
Ratification is the “adoption and confirmation by one person of an act or contract performed or entered into in his behalf by another who at the time assumed to act as his agent.”
Lincoln v. Aetna Cas. & Sur. Co.,
The Powells do not deny that William ratified Debbie’s purchase of the policy, nor do they deny that the form presented to Debbie, on which she signed William’s name, would have been sufficient had it been presented to and signed by William himself. For its part, Nationwide does not deny that William was a new applicant. Nor does it dispute that even when a named insured accepts an insurance agreement not containing UIM coverage, the policy must be reformed to include UIM coverage if no meaningful offer of UIM coverage has been rejected by the named insured.
Where the parties disagree is on the question of whether Nationwide’s offer of UIM coverage to Debbie was a “meaningful offer.” The Powells contend that no meaningful offer was made because the offer, including the information accompanying the offer, was presented not to the named insured, but to another person who, at least for purposes of summary judgment, was not authorized to act on his behalf. Nationwide responds that because the form it utilized was a proper one, its offer to Debbie was a meaningful offer as a matter of law. We agree with the Powells that Nationwide has not shown as a matter of law that the offer was meaningful.
As we have stated, in order to be a “meaningful offer” of UIM coverage, an offer must “intelligibly advise the insured
*206
of the nature of’ UIM coverage.
Wannamaker,
Nationwide maintains that it would be unjust to permit the Powells to obtain the benefits of the policy Debbie procured without binding them to Debbie’s rejection of UIM coverage. But this outcome is no more unfair than the result we would have if William had applied for the policy himself and specifically rejected an offer of UIM coverage, but Nationwide had failed to intelligibly advise him concerning the offer. In both cases, William would have entered into an agreement that did not contain UIM coverage. But in both cases, Nationwide’s failure to properly advise William regarding UIM coverage would deprive its UIM coverage offer of any legal effect and require that the policy be reformed. While the results in both cases might be viewed as undeserved windfalls for the Powells, a contrary result in either case would allow the insurer to avoid its duty to provide the critical UIM information in a commercially reasonable manner to the named insured, the individual who has the sole authority to decide whether to purchase UIM coverage. 6
Nationwide also contends that as a matter of law § 38-77-350(B) prevents reformation of the policy. We disagree. Nationwide has failed to demonstrate as a matter of law that it complied with that statute since the UIM form presented to Debbie was not, as the statute requires, “completed and executed by” William. Moreover, even if the statutory text could be construed to bar reformation when the named insured has ratified a putative agent’s unauthorized rejection of UIM coverage, such an interpretation would be directly at odds with the purpose of the meaningful-offer requirement for the reasons already discussed. Accordingly, we decline to interpret the statute in that manner.
See McDonald,
IV.
In sum, we conclude that the district court erred in holding as a matter of law that Nationwide’s presentation of the UIM form to Debbie constituted a meaningful offer of UIM coverage. Accordingly, we reverse the grant of summary judgment in favor of Nationwide and remand for further proceedings.
REVERSED AND REMANDED.
Notes
. Because we reverse the order granting summary judgment to Nationwide, we dismiss as moot the Powells’ appeal of the denial of their motion for relief from judgment.
. The record does not reflect whether at the time of the accident Debbie still had the policy containing UIM coverage that she had purchased from Nationwide on her own vehicle in February 1998.
. The parties agree that South Carolina law applies.
. It, is undisputed that the content of the UIM form met the requirements of § 38-77-350(A).
. Nationwide claims that the district court erred in concluding that Nationwide had not established as a matter of law that Debbie had actual authority to procure the insurance policy on her husband's behalf. We disagree. Because the Powells forecasted evidence that William only authorized Debbie to obtain a
*205
rate quote and an application from Nationwide, the district court properly identified a genuine issue of fact regarding Debbie’s agency.
See Estate of Hancock,
Although not raised by Nationwide, we have considered whether the Powells should be estopped from denying that Debbie was authorized to reject UIM coverage by virtue of her signing William's name to the appropriate forms. However, even if Debbie’s signing of William’s name constituted an implicit representation that she was authorized to do so, a party cannot be equitably estopped by virtue of her misrepresentation when the party to whom the misrepresentation was made could have acquired the true facts had it acted with reasonable diligence.
See Adams v. Adams,
. Because the Powells have offered evidence that Debbie was not authorized to reject UIM coverage on William's behalf, we do not address whether presentation of the appropriate form to someone authorized by the named insured to make the UIM coverage decision would constitute a meaningful offer.
