There is no American process for becoming a “Sir.” The Constitution bars every level of U.S. government from granting titles of nobility, so how to get the title Sir in America comes down to two realistic options: accept an honorary knighthood from a foreign government like the United Kingdom (which does not actually let you call yourself “Sir”), or legally change your first name to “Sir” through a court-ordered name change. Both paths have limits that surprise people, especially on passports and other government identification.
Why No U.S. Government Can Grant It
Article I, Section 9 of the Constitution bars the federal government from granting any title of nobility and blocks federal officeholders from accepting a title from a foreign government without Congressional approval.1Library of Congress. Article I Section 9 Clause 8 Titles of Nobility and Foreign Emoluments Article I, Section 10 extends the same prohibition to the states.2Library of Congress. Article I Section 10 No governor, legislature, or city council can create a knighthood of its own.
The language is deliberately broad, covering any title “of any kind whatever” from a foreign king, prince, or state absent Congressional consent. There is no domestic legal process to become a knight, lord, or baron. The title does not exist here as a legal concept.
Honorary Knighthoods From Foreign Governments
American citizens can receive knighthoods from foreign governments, most often from the United Kingdom. These are classified as “honorary” because the recipient is not a subject of the British Crown. Bill Gates, Steven Spielberg, Ralph Lauren, Angelina Jolie, and U.S. presidents including Dwight Eisenhower, George H.W. Bush, and Ronald Reagan have received honorary British honors.3The Gazette. American Citizens With Honorary British Knighthoods
Here is the catch. Honorary recipients can place post-nominal letters after their name (Bill Gates can write “KBE” after his), but they cannot style themselves “Sir” or “Dame.” That privilege is reserved for citizens of Commonwealth nations where the monarch is head of state.3The Gazette. American Citizens With Honorary British Knighthoods Even after a British honor for exceptional contributions to the arts, sciences, or diplomacy, in everyday use you are still just Bill or Steven.
These honors carry no legal weight in the United States. They do not change your legal name, grant privileges, or alter your standing under American law.1Library of Congress. Article I Section 9 Clause 8 Titles of Nobility and Foreign Emoluments
Extra Rules for Federal Employees and Military
Government workers face tighter constraints. Any federal employee who accepts a gift or decoration from a foreign government must report it to their employing agency. The agency head receives the decoration on behalf of the United States and disposes of it under federal regulations.4GovInfo. 5 USC 7342 – Receipt and Disposition of Foreign Gifts and Decorations Military personnel operate under a separate Department of Defense chart of foreign decorations that service members may accept and retain, including awards with ranks like “Knight” or “Commander” from countries ranging from the United Kingdom to the Vatican. Many are strictly honorary, meaning the service member can accept and keep the decoration but cannot wear it on a U.S. military uniform.5HRC – Army. Foreign Award Badge Chart 2 – Foreign Awards
Legally Changing Your First Name to “Sir”
This is the route most people actually mean when they ask the question. A court-ordered name change can make “Sir” your legal first name, the same way “Hunter” or “Duke” can be someone’s given name. It does not make you a knight or grant any nobility. It just puts the word in your legal name.
Filing the Petition
You file a name change petition with your local court, typically the circuit or superior court in the county where you live.6USA.gov. How to Change Your Name and What Government Agencies to Notify The petition asks for your current legal name, the name you want, and your reason. Many states also require disclosure of criminal history, including felony convictions, pending charges, or sex offender registration. A record does not automatically disqualify you, but it gives the judge more to weigh.
Publication and Hearing
Many states require you to publish notice of the proposed change in a local newspaper for a set period, often 30 days, before the court schedules a hearing. Publication costs generally run between $30 and $200. Not every state requires it, so check your court’s rules.
At the hearing, a judge reviews your petition. Judges have broad discretion. Approval is the norm for straightforward requests. A judge can deny a change that appears designed to defraud creditors, evade law enforcement, or mislead the public. Wanting to be called “Sir” because you like how it sounds is unlikely to trigger any of that. Wanting to be called “Sir” to impersonate a foreign dignitary might.
What It Costs
Court filing fees for name changes range roughly from $25 to $500 depending on jurisdiction, with most falling in the $150 to $350 range. Add the newspaper publication fee if required, plus certified copies of the court order for updating your records. Most courts allow a fee waiver if you cannot afford the cost.
How “Sir” Actually Appears on Government IDs
Even after a successful name change, “Sir” may not show up everywhere you expect. Federal and state ID systems draw a sharp line between a title and a first name, and the paperwork controls which side of that line you land on.
Passports
The State Department follows international guidelines that exclude titles and honorifics from passport names. Policy says ranks and titles may not appear in the applicant’s name on a passport, even if they appear on other identification. “Sir” is listed specifically as an example of a heraldic or honorific title that gets excluded.7U.S. Department of State. 8 FAM 403.1 Name Usage and Name Changes
There is a wrinkle. If your court order records “Sir” as your actual given name rather than a prefix, the State Department may include it, because the policy acknowledges that terms normally treated as titles can be genuine first names. The distinction is real: “Sir” as a title in front of your existing name gets stripped, “Sir” as a legal first name may survive. Expect questions either way, and bring your court order.7U.S. Department of State. 8 FAM 403.1 Name Usage and Name Changes
Social Security Cards
The Social Security Administration defines your legal name as your first and last name only. Middle names and suffixes are not part of the legal name for SSA purposes.8SSA. Defining the Legal Name for an SSN If your court order changes your first name to “Sir,” SSA should record it. If “Sir” is written as a prefix separate from the first name, SSA will likely drop it.
Driver’s Licenses and State ID
Under the REAL ID Act, state-issued identification must display your “full legal name.”9Homeland Security. REAL ID Act – Title II If your legal first name is “Sir,” your DMV should print it. DMV systems vary in how they treat names that look like titles, so bring the court order and be ready to explain.
Professional Licenses
If you hold a license in medicine, law, engineering, or a similar field, the board will require documentation of the legal name change, typically a certified court order. The board updates its records to match your new legal name.
“Sir” as Everyday Courtesy
Separate from any of this, “Sir” is widely used in the United States as a mark of respect when addressing men, particularly strangers. It carries no legal significance. Nobody needs a court order, a knighthood, or Congressional approval to be called “Sir” at a restaurant or by a colleague. Regional habits vary, and the usage is especially reflexive in Southern states, but it exists everywhere as basic politeness. If all you want is to be addressed as “Sir,” you already are, every time someone holds a door open for you.
