In this legal malpractice action, plaintiff appeals from a judgment dismissing his complaint for failure to state ultimate facts constituting a claim. ORCP 21A(8). Whether the complaint states a claim is a question of law. We treat as true the allegations and any inferences favorable to plaintiff that may be drawn. St. Paul Fire and Marine v. Continental Casualty, 112 Or App 209, 827 P2d 1366 (1992).

In February, 1988, plaintiff loaned Fisher $20,000 to expand a used car business. Fisher signed a note that promised that he would repay the loan in six months and pay plaintiff $1,000 monthly interest and that plaintiff would have a security interest in cars as collateral. In May, 1988, Fisher asked plaintiff for a $30,000 loan. They agreed that Fisher would repay the loan in seven months and pay plaintiff $3,000 monthly in interest and that plaintiff would have a security interest in cars.

At plaintiffs request, defendant drafted a security agreement and note for the second loan, which Fisher signed, and billed plaintiff for his services. Later, Fisher defaulted on both loans and became insolvent. Plaintiff sued Fisher, who counterclaimed that plaintiff was a loan shark engaged in racketeering. 1 After trial, the court gave plaintiff a $50,000 judgment for the principal of both loans but disallowed any interest.

Plaintiff then sued defendant for legal malpractice. He alleged that defendant was negligent in, among other things, failing to advise him that the loan interest rate was usurious, preparing documents that included the usurious rate and failing to perfect a security interest in the cars. He further alleged that, as a result, he was deprived of interest on the loan, had no security interest in the cars, was unable to collect on the $50,000 judgment and incurred legal costs enforcing the note and defending his reputation. 2 The court granted defendant’s motion to dismiss.

*219 Defendant does not dispute that he drafted a note that included usurious interest. See ORS 82.010(3). He argues that, because only the interest was unenforceable, the note had no effect on plaintiffs ability to recover the $50,000 judgment. See ORS 82.010(4). However, plaintiff also alleged that defendant failed to perfect a security interest in the collateral and that that made it impossible for him to collect any part of the loan principal after it was reduced to judgment. Defendant responds that it made no difference whether he perfected the interest, because plaintiff did not allege that he took possession of the car titles, and that that was a condition precedent to defendant’s duty to act. Neither the alleged facts nor the security agreement supports defendant’s argument that plaintiff had to possess the titles before he had a duty to act. The complaint alleges that he undertook to perfect the security interest and failed to do so. The allegations state a claim.

We do not consider defendant’s arguments based on allegations in the superseded original complaint, see O’Gara v. Kaufman, 81 Or App 499, 502, 726 P2d 403 (1986), and on a letter appended to the amended complaint that he relies on to state facts. See Oak Grove Parr v. McCutcheon Const., 275 Or 381, 384, 550 P2d 1382 (1976).

Reversed and remanded.
