Actually changing your "legal name" in many places isn't a "legal process" at all. Not if you mean a state-managed, form-filling exercise.
In the UK for example the law only specifies you must make a public declaration of your intent to use a new name (a notice in a local newspaper will do), and then completely abandon any all use of the old name. Even the venerable old 'Deed Poll' service is just a mechanism to make that initial declaration, it's actually a private register.
