*706 MEMORANDUM *

Greenwich Insurance Company (“Greenwich Insurance”) appeals the district court’s summary judgment in favor of Sharon and Duane Bankofíer (“the Banko-fiers”) in a diversity case brought by Oregon Realty against Greenwich Insurance. The district court ruled that Greenwich Insurance had a duty to defend the Banko-fiers in an underlying lawsuit then pending in Oregon state court. As the facts and procedural history are familiar to the parties, we do not recite them here except as necessary to explain our disposition. We have jurisdiction under 28 U.S.C. § 1291, and we affirm.

Under Oregon law,

[wjhether an insurer has a duty to defend an action against its insured depends on two documents: the complaint and the insurance policy.

The insurer has a duty to defend if the complaint provides any basis for which the insurer provides coverage.

Ledford v. Gutoski, 319 Or. 397, 877 P.2d 80, 82-83 (1994) (internal citations omitted).

Under Oregon Realty’s insurance policy, Greenwich Insurance had a duty to defend claims arising “in the performance of real estate services.” Here, the allegations in the complaint were sufficient to trigger Greenwich Insurance’s duty to defend the Bankofiers because the complaint contained allegations of “real estate services” related to the sale of the property. Among other things, the complaint alleges that the Bankofiers negligently structured the sale of the property to facilitate the subsequent investment of the sale proceeds. Thus, because the complaint provided a basis for which there is coverage, Greenwich Insurance had a duty to defend the Bankofiers.

Greenwich Insurance’s arguments that Exclusions E and J in the insurance policy bar coverage are unpersuasive. Exclusion E is inapplicable. Because the definition of the terms in Exclusion J are ambiguous, they should be construed in favor of the insured. “[I]f the policy is ambiguous, we are required to apply the rule that insurance policies are to be construed against the drafter.” Cain Petroleum Inc. v. Zurich Am. Ins. Co., 224 Or.App. 235, 241-42, 197 P.3d 596 (2008) (citing Hoffman Constr. Co. v. Fred S. James & Co., 313 Or. 464, 836 P.2d 703 (1992)).

AFFIRMED.
