Schultz’s account. Petitioner alleged that the Bank “owed a duty of reasonable care …, which included a duty

and of itself would not establish the Bank’s liability. The Bank would have been liable if it had failed to
exercise ordinary care when it added Holbrook’s name to Schultz’s account, thereby allowing Holbrook to
make unauthorized withdrawals from the account. As this opinion explains, however, Petitioner never
established the applicable standard of ordinary care, so he could not have proven that the Bank failed to
exercise ordinary care.
The Bank argues that expert testimony was necessary to establish the Bank’s standard of care, while Petitioner
contends that “a bank seeking to assist a customer to add a name to a checking account is an experience universally
shared.” Accordingly, Petitioner argues, no expert testimony was necessary to explain the Bank’s standard of care to
the jury. We disagree with Petitioner’s contention for a number of reasons. First, we cannot say with any certainty that
most people have added someone’s name to their bank accounts. Petitioner supports this contention by asserting that
“[l]ay people are frequently called upon in today’s society to prove their identifications.” We disagree that these
experiences provide a sufficient basis to conclude what the trier of fact would know because such experiences may
vary widely from the reasonable standards in the banking industry.FN16 Furthermore, the relevant activity in this case
was by the bank itself, not a bank customer. Even if most people have added a name to their bank accounts, most

traffic stops. There may be many reasons why banks might verify identification differently than airport security
agents or police officers. For example, banks may ordinarily request identification on a random basis when
