Part 3 - Enforcement of Instruments
§ 4-3-308. Proof of Signatures and Status as Holder in Due Course

Source: L. 94: Entire article R&RE, p. 858, § 1, effective January 1, 1995.
Editor's note: This section is similar to former § 4-3-307 as it existed prior to 1994.


The question of the burden of establishing the signature arises only when it has been put in issue by specific denial. "Burden of establishing" is defined in Section 1-201. The burden is on the party claiming under the signature, but the signature is presumed to be authentic and authorized except as stated in the second sentence of subsection (a). "Presumed" is defined in Section 1-201 and means that until some evidence is introduced which would support a finding that the signature is forged or unauthorized, the plaintiff is not required to prove that it is valid. The presumption rests upon the fact that in ordinary experience forged or unauthorized signatures are very uncommon, and normally any evidence is within the control of, or more accessible to, the defendant. The defendant is therefore required to make some sufficient showing of the grounds for the denial before the plaintiff is required to introduce evidence. The defendant's evidence need not be sufficient to require a directed verdict, but it must be enough to support the denial by permitting a finding in the defendant's favor. Until introduction of such evidence the presumption requires a finding for the plaintiff. Once such evidence is introduced the burden of establishing the signature by a preponderance of the total evidence is on the plaintiff. The presumption does not arise if the action is to enforce the obligation of a purported signer who has died or become incompetent before the evidence is required, and so is disabled from obtaining or introducing it. "Action" is defined in Section 1-201 and includes a claim asserted against the estate of a deceased or an incompetent.
The last sentence of subsection (a) is a new provision that is necessary to take into account Section 3-402(a) that allows an undisclosed principal to be liable on an instrument signed by an authorized representative. In that case the person enforcing the instrument must prove that the undisclosed principal is liable.
If a plaintiff producing the instrument proves entitlement to enforce the instrument, either as a holder or a person with rights of a holder, the plaintiff is entitled to recovery unless the defendant proves a defense or claim in recoupment. Until proof of a defense or claim in recoupment is made, the issue as to whether the plaintiff has rights of a holder in due course does not arise. In the absence of a defense or claim in recoupment, any person entitled to enforce the instrument is entitled to recover. If a defense or claim in recoupment is proved, the plaintiff may seek to cut off the defense or claim in recoupment by proving that the plaintiff is a holder in due course or that the plaintiff has rights of a holder in due course under Section 3-203(b) or by subrogation or succession. All elements of Section 3-302(a) must be proved.
Nothing in this section is intended to say that the plaintiff must necessarily prove rights as a holder in due course. The plaintiff may elect to introduce no further evidence, in which case a verdict may be directed for the plaintiff or the defendant, or the issue of the defense or claim in recoupment may be left to the trier of fact, according to the weight and sufficiency of the defendant's evidence. The plaintiff may elect to rebut the defense or claim in recoupment by proof to the contrary, in which case a verdict may be directed for either party or the issue may be for the trier of fact. Subsection (b) means only that if the plaintiff claims the rights of a holder in due course against the defense or claim in recoupment, the plaintiff has the burden of proof on that issue.
