DANA, J.
[¶ 1] The United States District Court for the District of Maine (Hornby, C.J.) has certified1 the following question: [400]*400“May a residential tenant be liable in sub-rogation to the insurer of a landlord for damages paid as a result of fire, absent an express agreement to the contrary in a written lease?” We answer the question as follows: No, a residential tenant may not be held liable in subrogation to the insurer of the landlord for damages paid as a result of a fire, absent an agreement to the contrary — that is, absent an express agreement in the written lease that the tenant is liable in subrogation for fire damage to the apartment complex.
I. BACKGROUND
[¶ 2] Denzil and Candice Snyder rented an apartment, pursuant to a written lease, at the Cortland Apartment Complex in South Portland in 1998, and independently obtained a “homeowners” insurance policy for coverage of their personal property as well as $300,000 in liability protection. The Snyders received a reduced rent because Candice worked as a leasing agent for the landlord, which involved meeting with new tenants to review the terms of the standard lease agreement. The owner of the apartment, Cortland Associates, was insured for fire and casualty losses by North River Insurance Company. The Snyders are not listed as named insureds in the insurance contract between Cortland and North River Insurance.
[¶ 3] In 1999 a fire at the apartment complex caused significant damage. North River Insurance alleges that the Snyders’ babysitter was smoking on the Snyders’ deck shortly before the fire began, and that the fire department determined that the fire was caused by her careless discarding of a cigarette.2
[¶ 4] Cortland recovered approximately $230,000 from North River Insurance, and North River filed a subrogation claim against the Snyders in federal court alleging that it suffered damage due to the Snyders’ negligence and breach of their lease with Cortland. The Snyders moved for a summary judgment contending that North River’s subrogation3 claim was barred because the Snyders were “co-insureds” under the policy North River provided to Cortland.4
[¶ 5] The Magistrate Judge (Cohen, M.J.) agreed with the Snyders and recommended that a summary judgment be granted because, as a matter of law, they were “implied” co-insureds under the landlord’s insurance policy with North River Insurance, and therefore could not be sued in subrogation (citing, inter alia, Sutton v. Jondahl, 532 P.2d 478 (Okla.Ct.App.1975)). The court premised its decision on the likelihood that “the Maine Law Court would adopt the Sutton doctrine,” yet recognized that “[t]here are no clear controlling precedents on this point in the deci[401]*401sions of the Law Court.”5 The magistrate concluded that certification would be appropriate to answer the question of a residential tenant’s liability to the landlord’s insurer for fire damage to the apartment complex, in the absence of an express agreement that informed the tenant that he would be liable in subrogation. The United States District Court agreed that the question should be certified.
II. DISCUSSION
A. Answering the Question
[¶ 6] Before addressing the merits, we assess the appropriateness of answering the certified question pursuant to 4 M.R.S.A. § 57 (Supp.2001) and M.R.App. 25(a).
[¶ 7] Both 4 M.R.S.A. § 57 and M.RApp. P. 25(a) provide that the federal courts may certify “one or more questions of law of this State, which may be determinative of the cause, [if] there are no clear controlling precedents in the decisions of the Supreme Judicial Court_” Our decisions reflect the added requirement that there be no dispute as to the material facts associated with the potentially determinative question or questions presented by the certification. See, e.g., Me. Green Party v. Sec’y of State, 1997 ME 175, ¶2, 698 A.2d 516, 517 (declaratory judgment action in which sole issue in dispute was meaning of statute governing disqualification of political party from official party status in Maine); Dasha v. Me. Med. Ctr., 665 A.2d 993, 995 (Me.1995) (medical malpractice action in which certified question relates only to the statute of limitations and not to the issue of liability).
[¶ 8] Here, there is no dispute as to the material facts associated with the question of whether a residential tenant can be liable in subrogation to the insurer of a landlord for damages paid as a result of a fire, absent an express agreement establishing such liability in a written lease. The decision of the Magistrate Judge which was affirmed by Order of the District Court establishes that there is no factual dispute as to the existence of a landlord/tenant relationship between Cortland Associates and Denzil and Candice Snyder; that North River Insurance paid damages to Cortland Associates as a result of a fire which started at the rental apartment leased by the Snyders; that there is no express provision in the written lease executed by Cortland Associates and the Snyders by which the Snyders can be held liable in a subrogation claim brought by the landlord’s fire insurance carrier; and that North River has brought an action for damages against the Snyders based upon subrogation. It is also undisputed that there are no clear controlling precedents on the Sutton doctrine in Maine, and our answer will, in one alternative, be determinative of the case.
[¶ 9] The existence of disputed facts with respect to separate issues not raised by the certified question which are themselves potentially determinative of the underlying action does not render it inappropriate for this Court to address the question or questions presented. The “[ejxercise of our jurisdiction is proper ... [if] there are no clear controlling prece[402]*402dents and our answer will, in one alternative, be determinative of the case. Dasha, 665 A.2d at 995. To hold otherwise would mean that we would answer certified questions only if they are the exclusive determinative questions generated by the case.” Such a restrictive view is inconsistent with the text and purpose of 4 M.R.S.A. § 57 and M.R.App. P. 25(a).
[¶ 10] The resolution of the factual dispute regarding responsibility for the fire that destroyed the Snyders’ apartment is not required to resolve the question of law presented to us. The threshold question of whether subrogation applies rests upon the nature and terms of the relationships between the landlord and the tenant, and the landlord and its insurer. The answer to this important threshold question need not be deferred pending the resolution of the secondary question of who is responsible for the fire. We therefore conclude that our exercise of jurisdiction is appropriate in this case.
B. The Merits
[¶ 11] North River argues that we should decline to adopt the so-called Sutton rule because it abrogates the terms of the insurance contract between the landlord and North River, and that tenants should be hable for their negligence.

B. The Merits
[¶ 11] North River argues that we should decline to adopt the so-called Sutton rule because it abrogates the terms of the insurance contract between the landlord and North River, and that tenants should be hable for their negligence. The Snyders argue that the “implied co-insured doctrine” is a sound, equitable rule, which explains why the majority of jurisdictions have adopted it.
[¶ 12] The “implied co-insured doctrine” 6 emerged in Sutton. The court held: “[S]ubrogation should not be available to the insurance carrier because the law considers the tenant as a co-insured of the landlord absent an express agreement between them to the contrary, comparable to the permissive-user feature of automobile insurance.” Id. at 482.
[¶ 13] In Sutton the tenant’s son started a fire by misusing his chemistry set; the insurance company covered the landlord’s $2,383 loss and then, as subrogee, brought suit against the father and son. Id. at 479. The insurer alleged “that the father contributed to the cause of the fire by breaching a duty to prohibit his son from carrying on unsupervised chemical experiments.” Id. The court’s decision was driven by its understanding that subrogation, as an equitable remedy, places the burden of loss where it ought to be — “it is a fluid concept depending upon the particular facts and circumstances of a given case for its applicability.” Id. at 482. The court reasoned that (1) “both [the] landlord and tenant have an insurable interest in the rented premises — the former owns the fee and the latter has a possessory interest”; (2) the landlords purchased fire insurance to “protect such interests ... [a]s a matter of sound business practice the premium paid had to be considered in establishing the rent rate”; and (3) it follows that “the tenant actually paid the premium as part of the monthly rental.” Id.
[¶ 14] The court noted that the landlord could have contracted for the tenant to buy fire insurance; the landlord, however, elected to purchase the insurance:
To suggest the fire insurance does not extend to the insurable interest of an occupying tenant is to ignore the realities of urban apartment and single-family dwelling renting. Prospective tenants ordinarily rely upon the owner of the dwelling to provide fire insurance for the realty (as distinguished from personal property) absent an agreement other[403]*403wise. Certainly it would not likely occur to a reasonably prudent tenant that the premises were without fire insurance protection or if there was such protection it did not inure to his benefit and he would need to take out another fire policy .... Perhaps this comes about because the companies themselves have accepted coverage of a tenant as a natural thing.
Id. Finally, the court articulated that the insurance company
should not be allowed to shift a fire loss to an occupying tenant even if ... negligently caused.... For to conclude otherwise is to shift the insurable risk assumed by the insurance company from it to the tenant — a party occupying a substantially different position from that of a fire-causing third party not in privity with the insured landlord.
Id. (emphasis added).
[¶ 15] Jurisdictions adopting Sutton do not agree in toto with the foregoing but advance alternative justifications for the rule. For example, the Supreme Court of Connecticut in DiLullo v. Joseph, 259 Conn. 847, 792 A.2d 819, 823 (2002), in a commercial lease7 situation, applied the Sutton rule because it disfavored economic waste. The court declared that allocating responsibility to the tenant to maintain sufficient insurance in anticipation of a subrogation claim is untenable: “Such a rule would carry a strong incentive for every tenant to carry liability insurance in an amount necessary to compensate for the value, or perhaps even the replacement cost, of the entire building, irrespective of the portion of the building occupied by the tenant.” Id. at 822-23 (emphasis added). Without the Sutton rule, two policies of insurance would be purchased for the same insurable interest, and the “waste would be compounded by the number of tenants.” Id. at 823.8 See also GNS P’ship, 873 P.2d at 1164 (holding that a tenant is presumed to be a coinsured absent an agreement to the contrary because “[t]his presumption is the most efficient way to allocate insurance costs”).
[¶ 16] For residential tenants, we agree with the rationale advanced in the DiLullo opinion. When the lease does not contain an express agreement addressing the issue of subrogation in the event of a negligently caused fire by a tenant, as the magistrate found in this case,9 a landlord’s [404]*404insurer may not proceed against the tenant as subrogee.
