OPINION
FIDEL, Presiding Judge.The parties are Utah residents. Plaintiff brought this tort claim against her husband in the Superior Court of Arizona for damages sustained in a single vehicle accident that occurred while they were traveling through Arizona from their Utah home. The parties married between the accident and the time plaintiff filed suit. The trial court granted defendant’s motion for summary judgment, holding that plaintiffs claim was barred by Utah’s law of interspousal immunity.
Arizona abrogated the interspousal immunity doctrine in 1982. On a question of intrafamily immunity, however, the law of the state of domicile, if ascertainable, takes precedence over the law of the state where the tort occurred. The dilemma in this case is that the Utah Supreme Court at least partially abrogated Utah’s law of interspousal immunity in 1980 but has chosen to leave the extent of abrogation unsettled since that time. The issues, therefore, on appeal are whether the trial court correctly interpreted *315Utah law, whether Utah law is indeed ascertainable, and whether the trial court instead should have applied Arizona law.
I. CHOICE OF LAW PRINCIPLES
Arizona courts are guided in choice of law questions by the Restatement of Conflict of Laws. Bates v. Superior Ct., 156 Ariz. 46, 48, 749 P.2d 1367,1369 (1988) (citing Schwartz v. Schwartz, 103 Ariz. 562, 565, 447 P.2d 254, 257 (1968)). The Restatement provides that, in a tort case, the law of the state with “the most significant relationship to the occurrence and the parties” must determine their rights and liabilities. Restatement (Second) of Conflict of Laws § 145(2) (1971) [hereinafter Restatement].
Section 6(2) of the Restatement lists general factors that help to identify the state with the most significant relationship to the action and the parties:
(a) the needs of the interstate and international systems,
(b) the relevant policies of the forum,
(c) the relevant policies of other interested states and the relative interests of those .states in the determination of the particular issue,
(d) the protection of justified expectations,
(e) the basic policies underlying the particular field of law,
(f> certainly, predictability and uniformity of result, and
(g) ease in the determination and application of the law to be applied.
Id. § 6(2).
In further guidance, section 145(2) lists contacts to be considered when applying the principles of section 6 to issues of tort law:
(a) the place where the injury occurred,
(b) the place where the conduct causing the injury occurred,
(c) the domicil, residence, nationality, place of incorporation and place of business of the parties, and
(d) the place where the relationship, if any, between the parties is centered.
Id. § 145(2).
Among the contacts listed in section 145(2), the most significant to a .question of interspousal immunity is not the place where injury occurred, but rather the spouses’ place of domicile. See Schwartz v. Schwartz, 103 Ariz. 562, 566, 447 P.2d 254, 258 (1968). This is because “the state of the family domicile ... has the primary responsibility for establishing and regulating the incidents of the family relationship____” Id. at 564,447 P.2d at 256 (quoting Emery v. Emery, 45 Cal.2d 421, 289 P.2d 218, 223 (1955)); see also Restatement § 169(2) (in questions of intrafamily immunity, the “applicable law will usually be the local law of the state of the parties’ domicil.”). Accordingly, because Utah, the domiciliary state, is the state of “most significant relationship,” we must attempt to determine and apply its law of interspousal immunity. In this case, however, a significant question arises concerning the “ease in the determination and application” of Utah law. See Restatement § 6(2)(g).
II. INTERSPOUSAL IMMUNITY IN UTAH LAW
Our examination of Utah law begins with Taylor v. Patten, 2 Utah 2d 404, 275 P.2d 696 (1954). There, by a 3-2 margin, the Utah Supreme Court reinstated a wife’s intentional tort claim against her husband. The court considered whether interspousal immunity was compatible with Utah statutes that enable wives to sue and be sued, enforce liabilities, and take actions to protect their rights “as if unmarried.” Id., 275 P.2d at 697 (citing Utah Code Ann. (“U.C.A.”) §§ 78-11-1, 30-2-2, and 30-2-4 (1953)). In the lead opinion, two members of the majority concluded:
From the foregoing it is clear that the legislature intended to establish the separate identity of the husband and wife in all property and personal rights the same as if they were not married. Giving these statutes a liberal construction to effect their objects and in the interest of justice requires us to hold that a wife can sue and be sued the same as if she were unmarried, even for the recovery of damages from her husband for intentional personal injury.
Id., 275 P.2d at 698.
The third member of the majority limited his concurrence to the facts—that the tort occurred while the parties’ divorce action was *316pending but unconcluded—and reserved judgment “as to the more comprehensive proposition that such a suit could be maintained at any time during the marriage relation.” Id., 275 P.2d at 699 (Crockett, J., concurring).
Nine years later, in Rubalcava v. Gisseman, 14 Utah 2d 344, 384 P.2d 389 (1963), a 4-1 decision written by Judge Crockett, who wrote the special concurrence in Taylor, the Utah Supreme Court overruled Taylor1 and held that a wife could not sue her husband for a tort arising during their marriage. The majority acknowledged, though with express reluctance, that “the idea that the husband is the master of the house”—an historic element of interspousal immunity—retained only “minimal” persuasive force. Id. at 391.2 Yet public policy continued to favor inter-spousal tort immunity, according to the majority, to prevent spouses from bringing collusive suits to collect from their insurers. Id. The majority found no impediment to this policy in the statutes discussed in Taylor v. Patten. Rather, the majority concluded, these statutes abolished interspousal immunity only in contract and property cases; had the legislature intended to abolish inter-spousal immunity in tort cases as well, it would have done so explicitly. Id. at 393.3
Rubalcava remained the last word on the subject for seventeen more years; but in Stoker v. Stoker, 616 P.2d 590 (Utah 1980), a still divided Utah Supreme Court reversed field once again. In Stoker, another intentional tort claim by a wife against her husband, the court turned to the statutes it had analyzed twice before and this time reaffirmed the interpretation given in the Taylor lead opinion. Id. at 592. The two dissenters, in an opinion by Justice Crockett, reiterated the Rubalcava argument that the legislature had abrogated interspousal immunity only in contract and property cases and had left inter-spousal tort immunity intact. Id. at 593-94. The three members of the majority, however, expressly rejected that analysis. Id. at 591. After quoting U.C.A. section 30-2-4; see supra note 3, the majority stated:
The statute authorizes [a wife] to prosecute and defend all actions for the preservation and protection of her rights and property, as if unmarried. It speaks of rights and of property in the disjunctive, and, all actions for the preservation and protection of her rights would certainly include a right to be free from an intentional tort of her husband.
Id. (emphasis added).
Stating farther that the Utah Married Women’s Act should be liberally construed so as to promote justice, the majority concluded:
*317To read into our Married Women’s Act, a proscription against a wife suing her husband, would be to construe it so strictly as to add a provision which the legislature did not put there.
Id.
The Utah Supreme Court has not revisited the issue of interspousai immunity since Stoker, though it has had three chances to do so. The question therefore confronts us whether the Stoker majority intended to limit its decision to the facts, rejecting interspousal tort immunity for intentional tort claims only, or whether it intended a wholesale rejection, not only in intentional tort claims but in negligence claims as well.
The Utah Supreme Court has twice recognized since Stoker that this question remains open. In a 1987 case, the court concluded that a household exclusion clause absolved a liability insurer of the duty to defend a husband in his wife’s personal injury suit. State Farm Mut. Auto. Ins. Co. v. Mastbaum, 748 P.2d 1042 (Utah 1987). In upholding the validity of the exclusion, the majority opinion chose not to address the issue of interspousai immunity. Justice Zimmerman, in a concurring opinion, explained:
Inasmuch as there are no grounds for reversing the instant case, I think it unnecessary for us to decide at this juncture whether Stoker v. Stoker, 616 P.2d 590 (Utah 1980), abrogated interspousai immunity with respect to actions grounded in negligence as well as those grounded in intentional torts.
Id. at 1044-45 (Zimmerman, J., concurring).
A year later, in Noble v. Noble, 761 P.2d 1869 (Utah 1988), the court expressly reserved the issue once again. In the parties’ divorce proceeding, the trial court found that the husband had intentionally shot his wife. When the wife brought a separate tort suit against the husband, the trial court dismissed her intentional tort claim as precluded by the prior divorce trial and dismissed her negligence claim as barred by interspousai immunity. Id. at 1370. The supreme court reinstated the intentional tort claim and held that the husband was estopped from denying that he had intentionally shot his wife. Id. at 1374-75. But the court declined to review dismissal of the negligence claim, explaining:
In Stoker, this Court held that [interspousai immunity] had been abrogated with respect to intentional torts____ We have never had occasion to decide whether this abrogation extended to negligence claims, and we do not do so in this case. It is unnecessary for us to reach that question because our disposition of [the wife’s] intentional tort action makes it a certainty that she will have a remedy for her injuries.
Id. at 1375 n. 7 (emphasis added).
In 1989, the court chose once again to leave the issue unresolved. In Forsman v. Forsman, 779 P.2d 218 (Utah 1989), a California couple had an automobile accident while driving through Utah, and the wife brought a negligence claim against her husband in the Utah courts. The trial court dismissed the suit on the ground of interspousai immunity; and the supreme court reversed, applying the law of California, the domiciliary state, without deciding the viability of interspousai immunity in negligence cases under Utah law. Id. at 220.
There are two ways to read Forsman. One way is to suppose that the court would not have considered the choice of law between California and Utah unless it had concluded that its own law differed from that of California. By this analysis, our dissenting colleague reads into Forsman an unarticulated determination that Utah continues to observe interspousai immunity in negligence actions. We think it unlikely, however, that the court would have chosen by silent indirection to resolve a question it had so pointedly declared unresolved in each of the two preceding years in Noble and State Farm. Rather, because California law had conclusive preference under established choice of law principles, deference to California gave the court a clear path to resolution and freed it a third time from deciding whether Stoker’s abrogation of interspousai immunity extended to negligence claims.4
*318III. APPLICATION OF STOKER RATIONALE
Because the Utah Supreme Court has chosen not to resolve the question “whether Stoker ... abrogated interspousal immunity with respect to actions grounded in negligence as well as those grounded in intentional torts,” State Farm, 748 P.2d at 1044-45, we have two alternative courses in this case. The first course is to try, by examining the reasoning of the Utah cases, to resolve the question Utah has chosen to leave open. The second is simply to accept the law of Utah as unsettled on this issue and fall back on Arizona law. We conclude that the first course is preferable. Where, as here, there is reasoning to guide us in predicting how the domiciliary state would resolve the case before us, we undertake the prediction in keeping with our policy of deference to domiciliary law on questions of interspousal immunity. Schwartz, 103 Ariz. at 566, 447 P.2d at 258.
We have deliberately defined our task as that of predicting how the Utah Supreme Court would resolve the case before us. In doing so, we analogize the role of a state court ascertaining and applying the common law of another state to that of a federal court obliged to ascertain and apply state common law. When an issue of state law arises in- federal court and there is no controlling decision by the state’s highest court, the federal court is obliged to predict what the state’s highest court would decide if confronted with the issue. E.g., Aetna Casualty & Sur. Co. v. Sheft, 989 F.2d 1105, 1108 (9th Cir.1993). Similarly, where, as here, “[t]he highest court of a state ... [has decided] analogous cases in conflicting and inconsistent ways,” the court of the forum owes it to the litigants to predict how the state court would resolve the conflict in the case at hand.5 Arthur L. Corbin, The Laws of the Several States, 50 Yale L.J. 762, 772 (1941). Professor Corbin put the matter sharply:
When the rights of a litigant are dependent on the law of a particular state, the court of the forum must do its best (not its worst) to determine what that law is. It must use its judicial brains, not a pair of scissors and a paste pot.
Id. at 775.
An example of the approach that Corbin commends is McKenna v. Ortho Pharmaceutical Corp., 622 F.2d 657 (3d Cir.1980). There, the Third Circuit, obliged to apply Ohio law, concluded that a prior Ohio Supreme Court holding, though never expressly overruled, had been so undermined by inconsistent subsequent reasoning as to warrant the prediction that the Ohio court would no longer similarly rule. Id. at 664-66. The court stated:
[O]ur prediction “cannot be the product of a mere recitation of previously decided cases.” In determining state law, a federal tribunal should be careful to avoid the “danger” of giving “a state court decision a more binding effect than would a court of that state under similar circumstances.” Rather, relevant state precedents must be scrutinized with an eye toward the broad policies that informed those adjudications, and to the doctrinal trends which they evince.
Id. at 662 (quoting Becker v. Interstate Properties, 569 F.2d 1203, 1205-06 (3d Cir.1977) and 1A James W. Moore et al., Moore’s Federal Practice ¶ 0.307, at 3077 (2d ed. 1979)).6 We similarly approach our predictive obligation in this case.
*319Proceeding therefore to the issue, we find that the rationale the Stoker court articulated in rejecting the doctrine of interspousal immunity applies equally to negligence cases as to cases of intentional torts. Grounding its decision in a Utah statute that authorized a married woman to prosecute and defend all actions for the preservation and protection of her rights and property, the Stoker majority wrote, “all actions for the preservation and protection of her rights would certainly include a right to be free from an intentional tort of her husband.” Stoker, 616 P.2d at 591. Our dissenting colleague may reason from the last part of the quoted sentence that Stoker applies only to cases of intentional torts. Yet if we look to Stoker’s reasoning, as we must, to predict how the court will resolve the undecided question of immunity in negligence cases, we cannot escape the paraphrase that “all actions for the preservation and protection of a married woman’s rights” would equally include a right to be free from a husband’s negligent tort.
Just as our colleague ignores the import of Stoker’s reasoning on this point, she also ignores that neither the Bubalcava opinion nor the Stoker opinion attributes any merit to the distinction she finds dispositive between negligence and intentional tort claims. Indeed, the Bubalcava majority pointedly rejected such a distinction, stating: “no basis can be found [in our statutes] for any distinction between intentional or unintentional torts. Under them the plaintiff either has a right to bring an action in tort, or she does not.” Bubalcava, 384 P.2d at 392 (emphasis added).
In short, because in Bubalcava the Utah Supreme Court decisively rejected any distinction, for purposes of interspousal immunity, between negligent and intentional torts, and because in Stoker that court rejected interspousal immunity for reasons that apply equally to negligent and intentional torts, we conclude that the Utah Supreme Court, if squarely presented with this case, would apply the reasoning of Stoker and hold that interspousal immunity has been abrogated in Utah in cases of negligent torts.
IV. EASE IN DETERMINATION AND APPLICATION OF UTAH LAW
Athough we have attempted to predict the course that Utah law will take, we acknowledge an element of guesswork in any such prediction. Between 1954 and 1980, the Utah Supreme Court twice reversed its interpretation of the governing statutes on the subject, each time by a divided court; and since 1980 the court has three times avoided deciding how its previous cases should be read. Because a future court might foresee-ably choose to reverse field once again, it would be a pretense for either the majority or the dissent to suggest that Utah law on this subject is clear.
Accordingly, we point out that an alternative basis for reversing summary judgment in this case is to fall back on Arizona law. Though the Restatement, as we have indicated, denotes a preference for domiciliary law on issues such as this, it also directs us to consider “ease in the determination and application of the law to be applied.” Restatement § 6(2)(g).7 In this case Arizona law, in contrast to Utah law, is readily determined. *320Interspousal immunity was unequivocally abolished for public policy reasons in Fernandez v. Rome, 132 Ariz. 447, 452, 646 P.2d 878, 883 (1982). Thus, should Utah law be regarded as indeterminate on this subject, we find that Arizona law permits the plaintiff to go forward with this case.
V. CONCLUSION
For the foregoing reasons, we reverse summary judgment entered for defendant and remand for further proceedings consistent with this opinion.
GRANT, J., concurs.. Judge Crockett indicated in a footnote that he regarded Taylor as distinguishable on the ground stated in his concurring opinion in that case— that the tort there had occurred while a divorce action was pending. He added, however, that he did not expect his "concurring colleagues to join in the expression of this footnote.” Rubalcava, 384 P.2d at 394 n. 17.
. An annotation on the subject describes the common law foundation of interspousal immunity as follows: "[I]t was said at common law that husband and wife were one person, and that person was the husband, so that it was both morally and conceptually objectionable to permit a tort suit between two spouses.” Wayne F. Foster, Annotation, Modem Status of Interspousal Tort Immunity in Personal Injury and Wrongful Death Actions, 92 A.L.R.3d 901, 906 (1979) [hereinafter Foster, 92 A.L.R.3d].
. U.C.A. § 30-2-4, discussed in both opinions, provided:
A wife may receive the wages for her personal labor, maintain an action therefor in her own name and hold the same in her own right, and may prosecute and defend all actions for the preservation and protection of her rights and property as if unmarried. There shall be no right of recovery by the husband on account of personal injury or wrong to his wife, or for expenses connected therewith, but the wife may recover against a third person for such injury or wrong as if unmarried, and such recovery shall include expenses ... paid or assumed by husband.
The lead opinion in Taylor emphasized the broad assertion in the first sentence of this statute that a wife has a general right to prosecute all actions for the protection of her rights. 275 P.2d at 697. The Rubalcava majority, however, interpreted the first sentence as limited to actions concerning wages and property. It emphasized instead the reference in the second sentence to the wife's right to recover against a third person, concluding that the legislature had only meant to free a wife to pursue a tort claim against a third person and not against her husband. 384 P.2d at 393.
. The dissent writes: "The Utah court had no reason to consider choice-of-law issues unless a conflict existed between Utah and California law on the immunity issue.” We find rather that, *318because California law clearly controlled, the Utah court had no reason to resolve what it had previously defined as an unsettled question of Utah law.
. Utah law is not only unsettled on the question whether interspousal tort immunity has been abrogated in negligence as well as intentional tort cases. This case presents the further question whether Utah would extend interspousal negligence immunity—if it still exists—to premarital torts. Utah has never addressed that question; it would present a matter of first impression in that state. Among the states that have declined as yet to abrogate common law immunity, some have held the doctrine inapplicable to premarital torts. See generally Foster, 92 A.L.R.3d at 940-44.

Helmerich & Payne, Inc., 698 F.2d 1075, 1078 (10th Cir.1983) (refusing to follow Oklahoma Supreme Court case decided by split court with strong dissent after predicting that Oklahoma Supreme Court would do likewise given intervening statute undermining policy underlying the decision); Warner v. Gregory, 415 F.2d 1345, 1347 (7th *319Cir.1969) (refusing to follow Illinois Supreme Court decision after concluding that an Illinois appellate court correctly predicted that the Illinois Supreme Court would do likewise); Fahs v. Martin, 224 F.2d 387, 398-99 (5th Cir.1955) (refusing to follow an 1897 Florida Supreme Court decision representing a minority view after predicting that the Florida Supreme Court would do likewise).
. Although we have not found any cases that offer an in-depth analysis of factor § 6(2)(g), some courts have considered that factor along with others in choosing forum law over that of another state. E.g., Flotech, Inc. v. E.I. Du Pont de Nemours Co., 627 F.Supp. 358, 363 (D.Mass.1985), aff'd, 814 F.2d 775 (1st Cir.1987) (choosing forum law in a product defamation and disparagement suit because it "is easily determinable” and "provides clear precedent directly on point”); Baird v. Bell Helicopter Textron, 491 F.Supp. 1129, 1147 (N.D.Tex.1980) (In a personal injury claim arising from a helicopter crash in the jungles of Surinam, with Canada the domicile of the plaintiffs and third-party defendants and Texas the domicile of the defendant and the place where the helicopter was manufactured and serviced, the court chose Texas law rather than Canadian law, explaining that for reasons of familiarity and ready availability of precedent, the law of the forum would be easier to apply.).
