Name change

A name change is the act or legal process of replacing or altering a person's name. It may be informal or require official registration, depending on the jurisdiction.

Deed poll: A legal document used in some jurisdictions to declare a change of name. In the United Kingdom, a deed poll can formally document an individual name change.
Marriage: A legally or socially recognized union between people. Marriage may lead one or both spouses to adopt a different surname.
Pseudonym: A name used by someone instead of their legal or usual name, often for a particular purpose. A pseudonym can be used publicly without replacing a person's legal name.
Identity document: An official document used to establish a person's identity. Documents may need replacement or amendment so their names remain consistent.
Court order: A directive issued by a court that establishes or requires a legal action. Some jurisdictions require a court order to approve or record a name change.
Divorce: The legal dissolution of a marriage. Divorce proceedings may allow a person to restore a former name.
Stage name: A professional name used by a performer instead of their personal name. A stage name changes public presentation without necessarily changing official records.
Know your customer: Procedures businesses use to verify customer identities and assess associated risks. Financial institutions may request updated evidence before changing an account name.
Civil registration: The official recording of vital events and civil-status details by a government authority. Updating civil registers can make a changed name consistent across government records.
Adoption: The legal creation of a parent-child relationship between people not biologically related as parent and child. Adoption can change a child's legal name along with their family relationships.
