The Pennsylvania oath of office is a short, constitutionally prescribed pledge that every elected and appointed official has to take, on the exact wording set by the state Constitution, before doing any of the work the office authorizes. Get it done on time, file the signed copy with the right office, and you are set. Skip it, delay it, or misfile it, and Article VI, Section 3 is blunt about the result: the person forfeits the office.1Pennsylvania General Assembly. Constitution of Pennsylvania – Chapter 6
The Exact Words You Have to Say
Pennsylvania does not leave the wording up to the person taking the oath. The Constitution prescribes it verbatim:
“I do solemnly swear (or affirm) that I will support, obey and defend the Constitution of the United States and the Constitution of this Commonwealth and that I will discharge the duties of my office with fidelity.”1Pennsylvania General Assembly. Constitution of Pennsylvania – Chapter 6
The same language is carried into 53 Pa.C.S. ยง 1141 as the standard form for municipal officials, so a township supervisor, borough council member, and cabinet secretary all say substantially the same thing.2Pennsylvania General Assembly. Title 53 – Municipalities Generally
The parenthetical “or affirm” is not decorative. If a sworn oath conflicts with your religious beliefs or personal convictions, you can affirm instead, and the affirmation carries the same legal weight. The U.S. Constitution reinforces this by prohibiting any religious test for public office.3Legal Information Institute. Article VI – U.S. Constitution
When You Have to Take It
The governing phrase in most Pennsylvania statutes is that the oath must be taken “before entering on the duties” of the office. It reads flexible; it is not. Courts treat it as a prerequisite, not a formality you can catch up on later.
Specific timing rules for common roles:
- County officers, along with their deputies, assistants, and clerks, must take and subscribe the oath before entering on their duties. Refusal is forfeiture of the office.4Pennsylvania General Assembly. Pennsylvania Consolidated Statutes Title 16, Section 12303 – Oath of Office
- City officers must take the oath before entering on their duties.5Pennsylvania General Assembly. Pennsylvania Consolidated Statutes Title 11, Section 10905 – Oath of Office, Violation of Oath and Penalty
- Gubernatorial appointees and deputy department heads must take the constitutional oath and file it with the Secretary of the Commonwealth.6New York Codes, Rules and Regulations. 71 P.S. Section 78 – Oath of Office
- Members of the General Assembly take the oath on the floor of their respective chamber, as the Constitution requires, before beginning legislative duties.1Pennsylvania General Assembly. Constitution of Pennsylvania – Chapter 6
- Notaries public have the strictest clock: the oath, bond, and commission must all be recorded within 45 days of appointment, or the commission is automatically void and the entire application process starts over.7Commonwealth of Pennsylvania. Revised Uniform Law on Notarial Acts (57 Pa.C.S.) – Section 321
Nobody is going to chase you down with a reminder. If you have just been elected or appointed, contact the clerk’s office or administering authority for your position soon after the results are certified. A week of proactive scheduling avoids a lot of trouble.
Who Administers It, and Where
The oath has to be given by someone with legal authority to administer it. In practice that means a judge, a magisterial district judge, or a notary public.
The setting depends on the office. A governor typically takes the oath in a public ceremony at the State Capitol, usually administered by a Pennsylvania Supreme Court justice. Legislators are sworn in on the floor of their chamber. New judges are commonly sworn in by a higher-ranking judge, often in a courtroom. Local officials have more latitude on venue. A township supervisor or borough council member might take the oath in the municipal building before a notary or local judge, and law enforcement officers usually swear in before a judge or magistrate as part of hiring.
Remote Administration
Pennsylvania permits remote online notarization, so the oath can be administered by a notary through audio-video technology rather than in person. The option grew during the COVID-19 pandemic and remains available for officials who cannot attend an in-person ceremony. You still appear before the notary in real time, just on a screen.
Where the Signed Oath Gets Filed
Taking the oath is only half the requirement. The signed document has to be filed with the right office, and an unfiled oath can create the same headaches as one that was never taken.
- Gubernatorial appointees and deputy department heads file with the Secretary of the Commonwealth.6New York Codes, Rules and Regulations. 71 P.S. Section 78 – Oath of Office
- County officers file in the office of the prothonotary of the county where the oath was administered.4Pennsylvania General Assembly. Pennsylvania Consolidated Statutes Title 16, Section 12303 – Oath of Office
- Township supervisors and other municipal officials generally file with the municipal secretary or clerk.
- Notaries public record the bond, oath, and commission with the recorder of deeds in the county where they maintain their office, within the 45-day window.7Commonwealth of Pennsylvania. Revised Uniform Law on Notarial Acts (57 Pa.C.S.) – Section 321
Recording fees vary by county. Call the prothonotary or recorder of deeds before you show up, and keep a copy of the filed document for your own records.
What Happens If You Skip It or Miss a Deadline
The consequences run from immediate to serious.
Forfeiture of the Office
The Constitution states it plainly: “Any person refusing to take the oath or affirmation shall forfeit his office.”1Pennsylvania General Assembly. Constitution of Pennsylvania – Chapter 6 The county officer statute echoes the same rule.4Pennsylvania General Assembly. Pennsylvania Consolidated Statutes Title 16, Section 12303 – Oath of Office For notaries, missing the 45-day recording deadline makes the commission automatically void.7Commonwealth of Pennsylvania. Revised Uniform Law on Notarial Acts (57 Pa.C.S.) – Section 321
Whether Your Official Acts Still Count
If you have been signing contracts, casting votes, or issuing decisions before your oath was properly completed, every one of those actions is potentially open to challenge. Pennsylvania courts have long recognized the de facto officer doctrine, which generally treats acts performed by someone holding office under color of authority as valid despite a procedural defect like a late oath. It exists to protect the public and third parties who relied in good faith. The protection runs to those affected by the official’s actions, though, not to the official, who still faces forfeiture.
Criminal Exposure
Pennsylvania law makes it a second-degree misdemeanor to falsely pretend to hold a public position with the intent to induce another to submit to that pretended authority.8Pennsylvania General Assembly. Pennsylvania Consolidated Statutes Title 18, Section 4912 – Impersonating a Public Servant The statute is aimed mainly at outright fabricators, but someone who exercises official power knowing the oath was never completed, and who takes steps to hide the deficiency, could face scrutiny under it. Pennsylvania’s official oppression statute separately makes it a second-degree misdemeanor for anyone acting in an official capacity to knowingly engage in illegal conduct that infringes on the rights of others.9Pennsylvania General Assembly. Pennsylvania Consolidated Statutes Title 18, Section 5301 – Official Oppression Criminal charges tied to oath problems are rare, but the tools exist.
The whole process, from raising your right hand to filing the paper, takes minutes. Putting it off can cost you the office you just won.
