¶ 1 The United States District Court for the District of Utah has certified to us for answers the following two questions: (1) whether, under Utah law, the negligent acts of a plaintiff in causing or contributing to the situation that the plaintiff hired a professional to resolve can be the basis for a comparative or contributory negligence defense, and (2) whether, under Utah law, a plaintiffs negligent acts in causing or contributing to *532 the situation the plaintiff hired a professional to resolve can be considered in determining causation and damages. We answer both questions “no.”
FACTS
¶ 2 For purposes of this opinion, we recite only those facts directly related to the certified questions. For a more complete statement of the facts, see
Steiner Corp. v. Johnson & Higgins,
ANALYSIS
¶ 3 The first question we must answer is whether the negligence of a plaintiff in causing or contributing to the situation that the plaintiff engages a professional to resolve can be the basis for a comparative or contributory negligence defense. Since comparative principles have previously been applied in cases dealing with contributory negligence, we will address the two doctrines together.
See Clover v. Snowbird Ski Resort,
¶ 4 The defenses of comparative and contributory negligence are sometimes available to tort defendants as a means of decreasing their liability.
See Ryan v. Gold Cross Servs., Inc.,
¶ 5 When applying these principles to professional negligence, other courts have barred contributory negligence defenses based on the plaintiffs actions taken before obtaining the services of a professional. The defenses have been barred regarding medical, legal, and accounting services.
See, e.g., Fullmer v. Wohlfeiler & Beck,
¶ 6 Steiner notes that despite employing slightly different analyses, the cases have a common thread: each reached its conclusions by focusing on the injury for which relief was sought in the case rather than on the condition for which the plaintiff sought professional help. We agree with this line of analysis. For example, in
Sendejar,
a plaintiffs negligence in injuring himself could not be contributory negligence because it was not “si
*533
multaneous[ ] with or co-operating with” the fault for which the plaintiff sought recovery.
¶ 7 In applying this reasoning, we conclude that a preexisting condition that a professional is called upon to resolve cannot be the cause, either proximate or direct, of the professional’s failure to exercise an appropriate standard of care in fulfilling his duties. To decide otherwise would allow professionals to avoid responsibility for the very duties they undertake to perform.
See Steiner II,
¶ 8 J&H’s main argument is that refusing to allow plaintiffs conduct which contributes to a situation that the plaintiff hired the professional to resolve to be the basis for contributory negligence would be paramount to adopting the actuarial benefit rule found in
National Surety Corp. v. Lybrand,
¶ 9 J&H also cites Utah case law allowing contributory negligence as a defense to professional negligence. It asserts that in reaching our conclusion today, we are creating an exception to general contributory negligence principles based on the professional status of a defendant.
See Birkner v. Salt Lake County,
¶ 10 Specifically, in
Birkner,
we held that a patient may negligently contribute to his or her injuries, notwithstanding a physician’s negligence, thus allowing a contributory negligence defense.
See
¶ 11 Similarly, in
Western Fiberglass,
the court of appeals affirmed a judgment that a plaintiff in an action against a law firm was contributorily negligent.
See
¶ 12 The second certified question is whether a plaintiffs negligent acts in causing or contributing to the situation that the plaintiff hired a professional to resolve can be considered in determining causation and damages. The foregoing analysis applies equally to this question.
¶ 13 Contributory negligence can be employed as a defense only if that negligence is “causally connected” to the injury.
See, Acculog,
¶ 14 The law is the same with respect to damages. Only when the negligence of the plaintiff is “causally connected” -to the injury can the damages awarded to the plaintiff be reduced proportionately. Thus, the court in
Lamoree v. Binghamton General Hospital,
