What document must a client provide to change her account name to her maiden name after a divorce?

To change an account name to a maiden name after a divorce, the client must provide the divorce decree. This document serves as legal proof of the name change as a result of the divorce proceedings. The divorce decree typically includes details about the individual's legal name change rights post-divorce, thus allowing the financial institution to update their records accordingly.

While other documents like a marriage certificate, birth certificate, or social security card may contain the name or marital history, they do not specifically confirm the authority to revert to the maiden name following a divorce. The divorce decree explicitly states the legal decision regarding the name change, making it the most appropriate and necessary document for this situation.
