Before PETERSON, C.J., and LINDE, CARSON, JONES, GILLETTE and VAN HOOMISSEN, JJ.
CARSON, Justice.
The sole issue concerns attorney fees to which defendant may be entitled under ORS 646.638(3).[1]
Plaintiffs[2] alleged that defendant misrepresented the existence of a septic system on property purchased from defendant. Their complaint pleaded claims for fraud and unlawful trade practices. See ORS 646.608. Plaintiffs also asked for attorney fees based on ORS 646.638(3).
Defendant contested plaintiffs' claims. Defendant also counterclaimed for attorney fees under ORS 646.638(3) on the basis that plaintiffs' unlawful trade practices claim was "frivolous."[3]
Defendant prevailed at trial on both the fraud and unlawful trade practices claims. The trial court found for defendant on his counterclaim under ORS 646.638(3), concluding that plaintiffs' unlawful trade practices claim was frivolous.
Defendant then requested attorney fees amounting to $14,609. Defendant's lawyer estimated that $2,000 in attorney fees was necessary solely to defend the unlawful trade practices claim. Defendant did not claim $528 in attorney fees related solely to defending the fraud claim. This left $12,609 in attorney fees apparently incurred to defend both claims.
When plaintiffs contested defendant's request for attorney fees, they argued that defendant was entitled only to attorney fees solely related to defending the unlawful trade practices claim (about $1,000 in plaintiffs' estimation). According to plaintiffs, defendant was not entitled to attorney fees necessary to defend both the fraud and unlawful trade practices claims.
The trial court agreed with plaintiffs. The court concluded that defendant was entitled to "only the incremental amount, or, to put it another way, that amount necessitated by the particular legal theory that [authorized] attorney's [sic] fees." In other words, the trial court concluded that it did not have authority to award attorney fees necessary to defend both the fraud and unlawful trade practices claims. Accordingly, the court awarded $2,000 in attorney fees to defendant.
*775 The Court of Appeals reversed the decision of the trial court. Estate of Wesley E. Smith v. Ware, 93 Or. App. 23, 760 P.2d 896 (1988). The Court of Appeals concluded that the trial court had authority "to award defendant attorney fees for services in defending the unlawful trade practices claim that also related to the defense of the fraud claim." Estate of Wesley E. Smith v. Ware, supra, 93 Or. App. at 26, 760 P.2d at 896. We affirm the decision of the Court of Appeals.
ORS 646.638(3) authorizes an award of reasonable attorney fees if the court finds an unlawful trade practices claim frivolous. The trial court found plaintiffs' claim frivolous, entitling defendant, in the court's discretion, to attorney fees incurred in defending the claim.
ORS 646.638(3) thus authorized an award  but it did not limit the award in the manner determined by the trial court. ORS 646.638(3) does not draw a distinction between: (1) Attorney fees solely related to defending an unlawful trade practices claim; and (2) attorney fees incurred in defending an unlawful trade practices claim and another claim.
Defendant apparently incurred attorney fees in defending the unlawful trade practices claim that he would have incurred whether plaintiffs alleged a fraud claim or not. It matters not that some of these fees also apparently related to defending the fraud claim. The trial court was authorized to award attorney fees necessary to defend the unlawful trade practices claim, regardless of whether those fees also were necessary to defend the fraud claim.[4]
Because the trial court did not award attorney fees under the rule we have announced, we remand the case to the trial court for determination of the award of attorney fees.
The decision of the Court of Appeals is affirmed. The case is remanded to the trial court for proceedings consistent with this opinion.
NOTES
[1]  ORS 646.638(3) provides:

"In any action brought by a person under this section, the court may award, in addition to the relief provided in this section, reasonable attorney fees at trial and on appeal and costs. If the defendant prevails, the court may award reasonable attorney fees at trial and on appeal and costs if it finds the action to be frivolous."
[2]  Plaintiff Wesley E. Smith died in 1987. His estate was substituted in his behalf.
[3]  Defendant also counterclaimed for attorney fees under ORS 20.105 for defending the unlawful trade practices claim. That statute would have permitted defendant to recover on plaintiffs' fraud claim upon a finding that the claim had been made "in bad faith, wantonly or solely for oppressive reasons." ORS 20.105(1). The trial court made no such finding (it denied defendant's counterclaim under ORS 20.105 with regard to the unlawful trade practices claim), and defendant did not assert that he was entitled to attorney fees for defending the fraud claim.
