N.C. Ct. of App.: Discover Bank v. Mustafaa: Plead Compulsory Counterclaims Early (and Don't Trust the AI Answer)

Summary:

While Discover Bank v. Mustafaa, No. COA26-284 (N.C. Ct. App. Aug. 5, 2026), is unpublished and not controlling authority, it is still a useful warning for consumer attorneys: counterclaims in a collection suit can be compulsory, and a late attempt to add them can cost the client those claims entirely.

Discover sued Mustafaa on a credit-card debt in November 2024. Mustafaa, proceeding pro se, answered with counterclaims under the FDCPA and UDTPA. He alleged, among other things, that Discover sought interest or fees the cardmember agreement did not authorize. The trial court dismissed those counterclaims in July 2025. In September 2025, Discover produced an updated cardmember agreement. Three weeks later, Mustafaa moved to amend his answer to add claims under the North Carolina Debt Collection Act.

The trial court denied the motion. From the bench, the judge said the case was over a year old, was being dragged out, and involved nothing that could not have been raised originally.

On appeal, the Court of Appeals held that the proposed NCDCA claims were compulsory counterclaims under Rule 13(a) because they arose from the same transaction as Discover's claim. That made the interlocutory denial immediately appealable.

Mustafaa still lost. Review was for abuse of discretion, and a trial court need not state specific reasons for denying amendment if a reason is apparent from the record. The Court found two. The first was undue delay: Mustafaa could have gotten his statements and cardmember agreement from his own account and should have known of the claims when he first answered. The second was futility: the new claims resembled those already dismissed.

Commentary:

More and more clients arrive with an answer to a collection suit that they drafted with an AI tool, and some have already filed it. These answers often raise familiar FDCPA and UDTPA theories, which frequently do not fit a claim by an original creditor, while leaving out NCDCA claims that might. Mustafaa shows why that matters.

Nothing in the opinion suggests Mustafaa used AI, but his pro se answer followed the same pattern, and once those claims were dismissed, his later attempt to add different claims failed. Review any answer the client has prepared or filed as soon as you see it.

If the creditor's claim involves unauthorized interest, fees, or improper collection conduct, the client may have NCDCA counterclaims. Those claims are also assets that need to be considered in the bankruptcy case: scheduled, exempted where available, and potentially used in connection with the creditor's proof of claim or pursued affirmatively.

But Mustafaa shows how quickly the state-court side can become a problem. Because the Court held these claims compulsory, leaving such a claim out of the answer—or losing a late motion to add it—may leave the debtor unable to pursue it later.

And the fact that Discover had not yet produced the updated agreement did not save Mustafaa here. The Court concluded that he could have accessed his statements and agreement himself and therefore should have identified the issue earlier. That reasoning may not apply where a consumer genuinely cannot obtain the operative agreement, but it makes waiting for the creditor to produce its documents risky.

So when a bankruptcy client has a pending collection suit, pull the agreement and statements, look for NCDCA claims, and make sure any claims are preserved in the state court and disclosed in the bankruptcy schedules.
