In any action which involves a consumer’s liability for an unauthorized electronic fund transfer, the burden of proof is upon the financial institution to show that the electronic fund transfer was authorized or, if the electronic fund transfer was unauthorized, then the burden of proof is upon the financial institution to establish that the conditions of liability set forth in subsection (a) have been met, and, if the transfer was initiated after the effective date of section 1693c of this title, that the disclosures required to be made to the consumer under section 1693c(a)(1) and (2) of this title were in fact made in accordance with such section.
In the event of a transaction which involves both an unauthorized electronic fund transfer and an extension of credit as defined in section 1602(e) [2] of this title pursuant to an agreement between the consumer and the financial institution to extend such credit to the consumer in the event the consumer’s account is overdrawn, the limitation on the consumer’s liability for such transaction shall be determined solely in accordance with this section.
Nothing in this section imposes liability upon a consumer for an unauthorized electronic fund transfer in excess of his liability for such a transfer under other applicable law or under any agreement with the consumer’s financial institution.
Except as provided in this section, a consumer incurs no liability from an unauthorized electronic fund transfer.
