Which document should a client provide when changing their account title?

A written statement of ownership is the correct document a client should provide when changing their account title. This document typically serves to clarify who the new owner is and may include details regarding the account, such as the existing title, the new title, and any relevant identification information for verification. By providing this statement, the client is confirming their claim to the account under the new title, which is essential for the financial institution to process the change accurately and securely.

Other options may not fulfill the specific requirements for changing an account title. For instance, a notary signature does not inherently indicate ownership but may serve to validate the authenticity of a document. A letter of explanation might offer context for the title change but lacks the formal verification of ownership that a written statement provides. A government-issued ID is crucial for confirming identity but does not serve to document the change in ownership itself. Thus, the written statement of ownership is the most comprehensive and appropriate document for this situation.
