Corporate entities in Nigeria risk having their banking facilities and factory loans frozen or denied outright when key corporate documents remain unstamped, a compliance gap that continues to catch many businesses off guard.
Under the Stamp Duties Act, certain instruments including loan agreements, debentures, board resolutions, share transfer forms, and other corporate documents must be duly stamped before they can carry legal weight. The Federal Inland Revenue Service (FIRS) is the primary authority responsible for administering stamp duties on corporate instruments.
When a company approaches a financial institution for credit, banks routinely require that all supporting documentation be properly stamped. An unstamped document is not admissible as evidence in civil proceedings, a position anchored in the Evidence Act. This means that should a dispute arise over a loan facility, the lender may be unable to enforce its rights against the borrower if the underlying agreement has not been stamped.
Financial institutions, aware of this risk, have grown increasingly cautious. Many now conduct thorough documentation audits before approving or renewing credit lines. Where an unstamped corporate document is discovered, the bank may freeze the affected facility or decline the application until the borrower regularises the instrument.
The implications extend beyond new loan applications. Existing facilities secured by unstamped debentures or charge documents could be suspended. For manufacturers relying on factory loans for working capital or equipment purchases, such a freeze could disrupt production schedules and strain supply chain commitments.
Rectifying the omission involves presenting the unstamped instrument to the FIRS for assessment and payment of the applicable duty, along with any penalties for late stamping. The process, while straightforward, can take time, potentially leaving businesses in a liquidity crunch while awaiting regularisation.
Advisers recommend that companies undertake immediate reviews of their document registers, particularly loan agreements, board resolutions authorising borrowing, and security documents. Early compliance is significantly cheaper than addressing the problem after a bank has flagged it.
For businesses currently negotiating credit facilities, ensuring that all documents are stamped before execution should be treated as a critical pre-condition to drawdown.
