This is different from a change of name; here, the individual keeps their official name but wishes to legally link a nickname or trade name to their identity.
Usage Cases
This is common among artists, entertainers, and politicians who have a "Stage Name" or "Political Nickname" that appears in media or contracts but does not match their birth certificate. For example, a musician named "David Adeleke" might swear an affidavit that he is also known as "Davido" to protect his intellectual property or receive payments made out to his stage name.
Legal Function
The affidavit states clearly: "I am [Official Name], also known as [Alias]." It asserts that both names refer to one legal entity. This is crucial for banking compliance, ensuring that cheques written to the alias can be deposited into the account of the official person without being bounced for third-party suspicion.
