§ 3420 Instrument Conversion Liability

Key Takeaways

  • •If someone takes a check or payment paper that isn't theirs and uses it, that's stealing (called 'conversion').
  • •The person who actually owns the check can sue for the money on it, but not for more than they're owed.
  • •Banks or people who accidentally handle a stolen check might not have to pay the full amount if they didn't know it was stolen.

Example

Your roommate finds your paycheck, signs your name, and cashes it without your permission.

This is stealing your check. You can sue your roommate for the amount of the paycheck, but not for extra money.

§ 3420 Instrument Conversion Liability

(a) The law applicable to conversion of personal property applies to instruments. An instrument is also converted if it is taken by transfer, other than a negotiation, from a person not entitled to enforce the instrument or a bank makes or obtains payment with respect to the instrument for a person not entitled to enforce the instrument or receive payment. An action for conversion of an instrument may not be brought by (1) the issuer or acceptor of the instrument or (2) a payee or indorsee who did not receive delivery of the instrument either directly or through delivery to an agent or a copayee. (b) In an action under subdivision (a), the measure of liability is presumed to be the amount payable on the instrument, but recovery may not exceed the amount of the plaintiff’s interest in the instrument. (c) A representative, other than a depositary bank, who has in good faith dealt with an instrument or its proceeds on behalf of one who was not the person entitled to enforce the instrument is not liable in conversion to that person beyond the amount of any proceeds that it has not paid out. (Added by Stats. 1992, Ch. 914, Sec. 6. Effective January 1, 1993.)
