Do I need a Deed Poll to double-barrel my surname?

Can You Use a Marriage Certificate to Double-Barrel Surnames After Marriage?

Most likely, yes. It is increasingly common in the UK for couples to join both spouses' surnames together into a double-barrelled name after marriage. Some government departments now accept a marriage certificate as sufficient proof for this naming convention.

However, many private companies may still require a Deed Poll to process the change. Having this universally recognised document ready can streamline the process and avoid delays when updating your name across various accounts and institutions.
