Is it true that refusal to sign an undertaking invalidates the document?

The assertion that refusal to sign an undertaking invalidates the document is false because a refusal to sign does not affect the validity of the undertaking itself. An undertaking is a formal agreement or promise, and it remains valid even if one party declines to sign it. The enforceability of the undertaking can still stand based on the actions taken before the refusal, the circumstances surrounding the agreement, or the context in which the undertaking was created.

Signing an undertaking may be a procedural necessity or a formality, but it is not the sole determinant of the document's validity. Consequently, even if an individual opts not to sign, the terms of the agreement can still apply, and both parties may be held accountable under the agreement, depending on relevant laws and practices. The nature of the documents and their enforceability can vary by jurisdiction, but the refusal to sign alone does not invalidate the undertaking universally.
