Colorado Code
Part 4 - Liability of Parties
§ 4-3-402. Signature by Representative

Source: L. 94: Entire article R&RE, p. 862, § 1, effective January 1, 1995.
Editor's note: This section is similar to former § 4-3-103 as it existed prior to 1994.
Cross references: For unauthorized signatures, see § 4-3-403.

It is questionable whether this exception was justified by the language of former Article 3 and there is no apparent policy justification for it. The exception is rejected by subsection (a) which returns to ordinary rules of agency. If P, the principal, authorized A, the agent, to borrow money on P's behalf and A signed A's name to a note without disclosing that the signature was on behalf of P, A is liable on the instrument. But if the person entitled to enforce the note can also prove that P authorized A to sign on P's behalf, why shouldn't P also be liable on the instrument? To recognize the liability of P takes nothing away from the utility of negotiable instruments. Furthermore, imposing liability on P has the merit of making it impossible to have an instrument on which nobody is liable even though it was authorized by P. That result could occur under former Section 3-401(1) if an authorized agent signed "as agent" but the note did not identify the principal. If the dispute was between the agent and the payee of the note, the agent could escape liability on the note by proving that the agent and the payee did not intend that the agent be liable on the note when the note was issued. Former Section 3-403(2)(b). Under the prevailing interpretation of former Section 3-401(1), the principal was not liable on the note under former Section 3-401(1) because the principal's name did not appear on the note. Thus, nobody was liable on the note even though all parties knew that the note was signed by the agent on behalf of the principal. Under Section 3-402(a) the principal would be liable on the note.
Case #1. Doe signs "John Doe" without indicating in the note that Doe is signing as agent. The note does not identify Richard Roe as the represented person.
Case #2. Doe signs "John Doe, Agent" but the note does not identify Richard Roe as the represented person.
Case #3. The name "Richard Roe" is written on the note and immediately below that name Doe signs "John Doe" without indicating that Doe signed as agent.
In each case Doe is liable on the instrument to a holder in due course without notice that Doe was not intended to be liable. In none of the cases does Doe's signature unambiguously show that Doe was signing as agent for an identified principal. A holder in due course should be able to resolve any ambiguity against Doe.
But the situation is different if a holder in due course is not involved. In each case Roe is liable on the note. Subsection (a). If the original parties to the note did not intend that Doe also be liable, imposing liability on Doe is a windfall to the person enforcing the note. Under subsection (b)(2) Doe is prima facie liable because his signature appears on the note and the form of the signature does not unambiguously refute personal liability. But Doe can escape liability by proving that the original parties did not intend that he be liable on the note. This is a change from former Section 3-403(2)(a).
A number of cases under former Article 3 involved situations in which an agent signed the agent's name to a note, without qualification and without naming the person represented, intending to bind the principal but not the agent. The agent attempted to prove that the other party had the same intention. Some of these cases involved mistake, and in some there was evidence that the agent may have been deceived into signing in that manner. In some of the cases the court refused to allow proof of the intention of the parties and imposed liability on the agent based on former Section 3-403(2)(a) even though both parties to the instrument may have intended that the agent not be liable. Subsection (b)(2) changes the result of those cases, and is consistent with Section 3-117 which allows oral or written agreements to modify or nullify apparent obligations on the instrument.
Former Section 3-403 spoke of the represented person being "named" in the instrument. Section 3-402 speaks of the represented person being "identified" in the instrument. This change in terminology is intended to reject decisions under former Section 3-403(2) requiring that the instrument state the legal name of the represented person.
