¶ 1. Philadelphia Indemnity Insurance Company appeals from a summary judgment dismissing its complaint against Cincinnati Insurance Company. Philadelphia Indemnity sought reimbursement of all or some of what it paid to settle claims of passengers injured when the driver of a van leased by Philadelphia Indemnity's insured, SIVA Truck Leasing, Inc., to the driver's employer ran the van into a barrier on an interstate highway. Cincinnati Insurance insured the driver's employer, Milwaukee Careers Cooperative. The trial court held that Philadelphia Indemnity could not recover under any of Philadelphia Indemnity's subrogation/contribution theories because Philadelphia Indemnity and SIVA had defaulted in an action brought against them by the injured passengers. We reverse.
I.
¶ 2. SIVA Truck Leasing leased a multi-passenger van to Milwaukee Careers Cooperative for the latter's use in its business of taking people to their jobs. This appeal concerns the action filed by four of the injured passengers. Their lawsuit originally named Milwaukee Careers Cooperative, its insurer Cincinnati Insurance, the van's driver, Carlos Bates, and another Milwaukee Careers Cooperative insurance carrier that is not a party to this appeal. Some four months later, the passengers added SIVA Truck Leasing and Philadelphia Indemnity as defendants, alleging that by insuring SIVA Truck Leasing, Philadelphia Indemnity undertook to pay damages that might have been caused by *592 the negligence of anyone who drove SIVA's van with SIVA's consent, and that this included Bates. Neither SIVA Truck Leasing nor Philadelphia Indemnity answered this complaint timely, and default judgment was entered against them. The validity of this default judgment is not an issue on this appeal. The plaintiffs dismissed with prejudice and by stipulation the defendants Cincinnati Insurance, Milwaukee Careers Cooperative, and Bates.
¶ 3. After default judgment was entered against them, SIVA Truck Leasing and Philadelphia Indemnity settled with the passenger/plaintiffs for more than $500,000, and then, as noted, Philadelphia Indemnity brought this action seeking reimbursement from Cincinnati Insurance, whose insurance policy covered Bates, the Milwaukee Careers Cooperative van driver. Philadelphia Indemnity's complaint against Cincinnati Insurance set out a map for relief with many roads: Wis. Stat. ch. 113, the Uniform Joint Obligations Act; common-law contribution; equitable subrogation; and indemnification based on a clause in the lease contract between SIVA Truck Leasing and Milwaukee Careers Cooperative. As we have seen, the trial court held that none of these routes were available to Philadelphia Indemnity because Philadelphia Indemnity had defaulted.

¶ 4. Our review of a trial court's grant of summary judgment is
de novo. Green Spring Farms v. Kersten,
¶ 5. It is paradigm in our law that persons who are liable to another should, if possible, pay only their fair share of that liability, and, variously, the mechanism to ensure this can be "subrogation,"
General Accident Insurance Co. of America v. Schoendorf & Sorgi,
¶ 6. "When no express agreement confers a right of contribution, a party's right to seek contribution against another is premised on two conditions: (1) the parties must be liable for the same obligation; and (2) the party seeking contribution must have paid more
*594
than a fair share of the obligation."
Kafka v. Pope,
¶ 7. Further, neither the plaintiffs' dismissal of Cincinnati Insurance, nor Philadelphia Indemnity's settlement with the plaintiffs stands in the way of Philadelphia Indemnity's claim for contribution. As
Fire Insurance Exchange
recognizes, contribution "can also be based on a settlement of what is contended to be joint liability, with the settling party being required to prove that: (1) both parties were obligated to the payee; (2) the amount of the payment was reasonable; and (3) the proportionate fault with negligent tortfea-sors, or other apportionment method when negligence is not the basis for mutual liability [sic]."

App 82, ¶ 8,
¶ 8. We now turn to the Kafka criteria. Both are satisfied here.
A. Liability for same obligation.
¶ 9. Philadelphia Indemnity's liability for the injuries suffered by Bates's passengers was based on Bates's alleged negligence, which Philadelphia Indemnity cannot contest because it defaulted. As we have seen, Cincinnati Insurance also provided coverage for Bates's alleged negligence. Thus, as noted, the liability of both insurance companies stems from the same obligation — insurance coverage for Bates's alleged negligence. Philadelphia Indemnity's liability-by-default does not change the calculus. A claim for contribution "is unaffected by the underlying transaction,"
Schara,
B. Unequal payment.
¶ 10. Whether Philadelphia Indemnity's payment of more than $500,000 to settle the passengers' claims was more than its fair share depends on whether Bates was negligent so as to trigger Cincinnati Insurance's liability to the plaintiffs for his negligence. As we have seen, Philadelphia Indemnity's default determined that Bates was negligent insofar as its liability to the passengers was concerned. The record is not clear whether Bates's negligence has also been determined in an action that might affect Cincinnati Insurance's liability.
See Jensen v. Milwaukee Mut. Ins. Co.,
¶ 11. We reverse the judgment and remand for further proceedings to give Philadelphia Indemnity the chance to prove, if it can, that Bates was negligent, that what it paid in settlement was reasonable, and that it bore more than its fair share of Bates's responsibility for the plaintiffs' injuries.

By the Court. — Judgment reversed and cause remanded.
