how does a person change their last name
Name change The procedures and ease of a name change vary between jurisdictions. In general, common law jurisdictions have loose procedures for a name change while civil law jurisdictions are more restrictive.
Suffix (name) A name suffix,[dubious â€“ discuss] in the Western English-language naming tradition, follows a person's full name and provides additional information about the person. Post-nominal letters indicate that the individual holds a position, educational degree, accreditation, office, or honor (e.g. "PhD", "CCNA", "OBE"). Other examples include generational designations like "Sr." and "Jr." (or often "Snr" and "Jnr" in British English) and "III", and legal ones such as "Estate" and (French) Feme Covert.
