The Extension Request Letter is a crucial business document used in Nigerian commercial practice when a party needs to formally request additional time to fulfill contractual obligations. This document type is particularly relevant when unforeseen circumstances, project complexities, or other valid reasons necessitate an extension of originally agreed timelines. The letter must comply with Nigerian contract law and business regulations, requiring clear articulation of the reasons for extension, current project status, and proposed new deadlines. It serves as an official communication tool and, when accepted, becomes part of the contract documentation. The document is commonly used across various sectors and should be drafted with careful attention to detail, as it may have legal implications and impact project timelines and deliverables.
