The right to retain your name after marriage is typically protected by your fundamental right to personal autonomy and privacy. While laws regarding name change after marriage can vary depending on the country and jurisdiction, many places recognize an individual's right to choose their own name, including whether or not to change it after marriage.
In most Western countries, there is no legal requirement for a person to change their name upon marriage. It is considered a personal choice, and individuals have the freedom to keep their birth name (also known as the "maiden name" or "surname") if they wish.
It's important to note that specific laws and regulations can differ based on where you live. Therefore, it is recommended to consult the laws in your country or state to confirm your rights regarding name change after marriage. Seeking legal advice or speaking with a family law attorney in your area will provide you with more accurate and up-to-date information regarding your rights and options related to your name after marriage.
