Nigeria’s Corporate Affairs Commission (CAC) announces it will begin enforcing statutory requirements for the contents of company business letters on 1 August 2026. In public notices circulated through its official channels, the commission says the enforcement targets compliance with the rules on what companies should include on their business letters. CAC warns that companies that fail to meet the requirements will face sanctions provided under applicable law. Premium Times reports that the commission states enforcement will take effect from 1 August and that both non-compliant companies and customers connected to such non-compliance will be subject to penalties prescribed by law. Daily Post Nigeria similarly reports that CAC starts enforcement of the company letter rules on August 1 and cautions that defaulting companies will be sanctioned. Both accounts frame the move as an extension of CAC’s regulatory oversight aimed at ensuring statutory conformity in corporate communications. The notices do not outline specific penalties in the excerpts provided, but they indicate enforcement will apply from the stated date for non-compliance with the business letter requirements.
