An affidavit is a written statement you swear is true. That sounds like a technicality until you notice what sits behind it: swearing to something false is a criminal offence, and the notary’s job is to make the swearing real rather than ceremonial.
The notarial act is different
Most documents brought to a notary need an acknowledgment — confirmation that you signed willingly and understood what you were signing. An affidavit needs something else: a verification on oath or affirmation.
| Acknowledgment | Verification on oath | |
|---|---|---|
| What you are confirming | That you signed it | That the contents are true |
| Is an oath administered? | No | Yes |
| When you sign | May be signed beforehand | Must be signed in the notary’s presence |
| Consequence of a falsehood | None from the notarial act | Perjury exposure |
| Maximum Pennsylvania fee | $5.00 first individual | $5.00 |
| Typical documents | Deeds, powers of attorney, titles | Affidavits, sworn statements, declarations |
The practical difference is the one that catches people out. With an acknowledgment, arriving with the document already signed is usually fine. With an affidavit it is not — and you will be asked to execute a fresh copy.
Bring it unsigned. Most people cannot tell from looking at a document which notarial act it requires, and the notary can only determine that once they read the certificate wording. Arriving unsigned costs nothing and avoids a wasted trip — the same rule set out in what to bring to a notary appointment.
What actually happens at the appointment
- The notary verifies your identity from current government photo identification bearing your signature.
- The notary administers the oath or affirmation. This is spoken aloud, and you respond. It is not a formality skipped for convenience.
- You sign, in the notary’s presence.
- The notary completes the certificate and applies their official stamp.
Step two is where affidavits differ most visibly from routine notarizations. A notary who slides the document across without administering an oath has not performed a verification, whatever the certificate says afterwards.
Oath or affirmation
You may be offered a choice. An oath invokes a religious appeal; an affirmation is a plain secular promise to tell the truth.
They are legally identical. Same weight, same consequences, same certificate. Choose whichever sits comfortably with you and say so — no explanation is required or expected.
Affidavits people commonly need
| Document | Typically used for |
|---|---|
| Affidavit of residency | School enrolment, in-state rates, benefits applications |
| Affidavit of identity | Reconciling name differences across documents |
| Affidavit of support or income | Immigration and financial sponsorship |
| Affidavit of gift | Vehicle transfers claiming the sales tax exemption |
| Small estate affidavit | Modest estates without full administration |
| Affidavit of loss | Replacing a lost document or instrument |
| Sworn statement of fact | Insurance claims and disputes |
The affidavit of gift will look familiar to anyone who has transferred a vehicle. Form MV-13ST is a sworn statement that nothing of value changed hands, signed under penalty of perjury by both parties — covered in full in gifting a car in Pennsylvania.
What a notary cannot do with your affidavit
The boundary here is firmer than with most documents, because affidavits invite exactly the questions a notary may not answer.
- Draft it. Writing the substance of your statement is practising law.
- Tell you what to say, or how to phrase something to achieve a result.
- Advise whether it will satisfy the court, agency or institution asking for it.
- Notarize a statement with blanks still in it.
- Proceed if you appear not to understand it, or seem to be signing under pressure.
If you do not know what your affidavit should say, that is a question for a lawyer or for whoever requested it. Many organisations supply their own template, which is usually the fastest route.
Why the oath is taken seriously
A sworn affidavit is evidence. Courts, insurers, immigration authorities and government agencies act on it without the author being present to question.
That is why a false statement carries criminal exposure for perjury or unsworn falsification. It is also why the notarial act is structured the way it is — identity verified, oath administered, signature witnessed — rather than a stamp applied to a page someone brought in.
If your affidavit is going overseas
A Pennsylvania notarization is recognised across the United States, but a document heading to a foreign government usually needs a further step: an apostille or certification from the Department of State, confirming that the notary who signed it holds a genuine commission.
That is a separate process handled at state level after the notarization, not something completed at the notary counter. If your affidavit is bound for another country, ask the requesting body whether they need an apostille before you go — it saves executing the document twice.

Frequently asked questions
What is the difference between an affidavit and an acknowledgment?
An acknowledgment confirms you signed a document willingly and understood it. An affidavit involves swearing the contents are true, which the notary handles as a verification on oath or affirmation. The second carries perjury exposure; the first does not.
Do I have to sign my affidavit in front of the notary?
Yes. A verification on oath or affirmation requires you to sign in the notary’s presence, after the oath is administered. Signing at home first invalidates the act and you will be asked to start again.
How much does it cost to notarize an affidavit in Pennsylvania?
The maximum fee for taking a verification on oath or affirmation is $5.00, and $5.00 for administering an oath or affirmation. Pennsylvania caps notary fees by regulation, so no notary may charge more.
Can a notary write my affidavit for me?
No. Drafting the substance of a legal document is practising law, which a notary is not permitted to do. You bring the completed statement; the notary handles the oath, the identity check, and the certificate.
What is the difference between an oath and an affirmation?
An oath invokes a religious appeal; an affirmation is a secular promise. They carry identical legal weight and identical consequences for a false statement, so choose whichever you are comfortable with.
What happens if I swear something untrue?
A false statement in a sworn affidavit exposes you to criminal liability for perjury or unsworn falsification, depending on the circumstances. This is the reason the notarial act exists — the oath is the point, not a formality.
