Which document is typically needed to demonstrate a name change?

The document that is typically needed to demonstrate a name change is a marriage certificate or court order. This is because a marriage certificate establishes a legal name change due to marriage, while a court order is necessary in cases where an individual has changed their name through legal proceedings. Both documents serve as official proof of the name change, which is required when applying for various legal processes, including the N-400 Application for Naturalization.

Using a social security card or driver's license may provide supporting evidence of identity, but these documents do not inherently prove a legal name change. A utility bill may show an address and a name, but it lacks the legal documentation necessary to substantiate that an official name change has occurred. Thus, the marriage certificate or court order is the recognized legal proof required in this context.
