Is Proof of Handwriting of Signatory Mandatory in Forged Promissory Notes in Commercial Suits?

In commercial contract litigation before Nigerian superior courts, lenders frequently sue to enforce repayment of substantial loans secured by executed promissory notes and bills of exchange.

When the corporate defendant denies executing the negotiable instrument, pleading the equitable defense of non est factum (it is not my deed) and alleging forgery, the evidentiary burden shifts regarding handwriting proof.

Under Section 101 and Section 102 of the Evidence Act 2011, the genuine signature and handwriting of the signatory on a physical promissory note must be proven by direct testimony, expert handwriting comparison, or court comparison with undisputed standards.

Step-by-Step Procedure to Resolve This Legal Matter:

  1. Preserve Contemporaneous Evidence: Collate physical receipts, verified bank timestamps, stamped letters, and electronic communication logs prior to formal intervention.
  2. Deliver Statutory Pre-Action Notice: Issue a formal written demand outlining the specific statutory breach and giving the opposing party statutory time to remedy the grievance.
  3. Engage Accredited Legal Counsel: Initiate judicial proceedings before the competent court of record or submit an official petition to the relevant regulatory commission.

Under Section 30 of the Bills of Exchange Act (Cap. B8, LFN 2004), while every holder of a bill is prima facie deemed to be a holder in due course, once fraud or forgery is affirmatively pleaded and substantiated, the burden shifts back to the holder.

Key Evidential Considerations & Statutory Benchmarks:

  • Documented statutory breach and verified timeline of events.
  • Jurisdictional competence of the regulatory agency or superior court.
  • Contemporaneous written correspondences, notices, and financial records.
  • Quantifiable proof of pecuniary loss or civil rights violation.

“The rule of law ensures that statutory rights and duties cannot be compromised by informal arrangements or administrative fiat; every citizen has the constitutional right to due process.”
— Nigerian Legal Precedent & Constitutional Jurisprudence

Where the plaintiff fails to produce expert forensic testimony or credible witness evidence verifying that the forged signature was penned by the authorized drawer, the action on the promissory note must fail.

The Court of Appeal in commercial debt recovery disputes has ruled that a forged signature on a negotiable instrument is completely null and void under Section 24 of the Bills of Exchange Act, imparting no legal rights.

Under Section 24 of the Bills of Exchange Act, a forged or unauthorized signature on a bill is wholly inoperative to bind the purported drawer.

Under Section 108 of the Evidence Act 2011, the court is legally empowered to examine questioned signatures under magnification to detect forgery.

In accordance with Section 36 of the Constitution of the Federal Republic of Nigeria 1999 (as amended), every person is entitled to a fair hearing within a reasonable time by a court or other tribunal established by law.

Under Section 1(1) of the 1999 Constitution, the Constitution is supreme and its provisions shall have binding force on all authorities and persons throughout the Federal Republic of Nigeria.

Section 6 of the 1999 Constitution vests judicial powers of the Federation in the courts established for the Federation, ensuring judicial review over administrative, corporate, and customary determinations.

Pursuant to the Evidence Act 2011, the burden of proof in civil proceedings rests upon the party who asserts the affirmative of the issue, requiring proof on the balance of probabilities.

The Supreme Court of Nigeria has repeatedly affirmed that rules of procedure and statutory compliance are designed to ensure substantial justice rather than technical defeat of constitutional and statutory rights.

Under the Interpretation Act (Cap. I23, LFN 2004), enactments must be interpreted purposively to give effect to the intention of the legislature while preserving established common law and equitable doctrines.

Fundamental human rights enshrined under Chapter IV of the 1999 Constitution (as amended) remain paramount and non-derogable except in strictly specified instances sanctioned by law.

For direct regulatory verification, official complaints, or accessing statutory registers without third-party fees, members of the public can consult the official portal of the Central Bank of Nigeria (CBN) Consumer Protection Portal.

Administrative bodies and regulatory agencies exercising quasi-judicial powers must observe natural justice: audi alteram partem (hear both sides) and nemo judex in causa sua (no one should be a judge in their own cause).
