2.4 Depositions and Affidavits
Key Takeaways
An affidavit is notarized as a jurat: identify the affiant, administer an oath or affirmation, watch the affiant sign in your presence, then complete the jurat and seal.
In a deposition the notary's role is limited to administering the oath to the deponent and, where authorized, certifying the record — never questioning, coaching, summarizing, or advising.
An oath invokes a higher power ('I swear') while an affirmation is a secular pledge ('I affirm'); both carry the same legal force and equal penalty for perjury.
A notary must not perform a deposition or notarize an affidavit in which they have a personal or financial interest, or are a party to the underlying matter — impartiality is mandatory.
A false statement in a sworn affidavit or deposition exposes the affiant or deponent to perjury, which is why the oath, not just the signature, is the operative element.
Sworn Statements: The Common Thread
Notaries are frequently the officers who place people under oath. Two settings dominate the exam: affidavits (written sworn statements) and depositions (oral sworn testimony taken outside court). Both turn on the same operative element — a properly administered oath or affirmation — and both expose the swearer to perjury if the statement is knowingly false.
Oath vs. Affirmation
| Oath | Affirmation | |
|---|---|---|
| Form | Invokes a higher power: "Do you swear...so help you God?" | Secular pledge: "Do you affirm...under penalty of perjury?" |
| Who chooses | The affiant/deponent may choose either | Same |
| Legal force | Full | Identical to an oath |
| Perjury exposure | Yes | Yes |
The two are legally interchangeable. A signer who objects to swearing on religious grounds may affirm with no loss of legal effect. A notary who refuses to offer the affirmation alternative commits misconduct in many states.
Affidavits Are Jurats
An affidavit is a written statement of facts made voluntarily and confirmed by the oath or affirmation of the person making it — the affiant. Notarizing an affidavit is a jurat, and the candidate must reproduce the jurat steps in order:
- Identify the affiant (personal knowledge, ID document, or credible witnesses).
- Administer the oath or affirmation — the affiant swears the contents are true.
- Watch the affiant sign the affidavit in the notary's presence (presence is mandatory for a jurat).
- Complete the jurat certificate ("Subscribed and sworn to before me...").
- Affix the seal, sign, and record the act in the journal.
Because a jurat vouches that an oath was taken, the notary may not notarize an affidavit the affiant signed earlier and elsewhere — the oath and signing must happen before the notary.
| Common affidavit | Purpose |
|---|---|
| Affidavit of Identity | Confirms a person's identity for legal use |
| Affidavit of Residence | Establishes where a person lives |
| Affidavit of Support | Guarantees financial support (immigration) |
| Affidavit of Heirship | Identifies heirs of a decedent |
| Affidavit of Service | Confirms legal papers were delivered |
| Financial Affidavit | Sworn statement of income, assets, debts |
Depositions: A Strictly Limited Role
A deposition is sworn testimony taken from a witness — the deponent — outside a courtroom, usually during the discovery phase of a civil lawsuit. The notary's role is narrow:
- Administer the oath or affirmation to the deponent before testimony begins.
- Where state law authorizes it, certify the record — that the testimony was given under oath.
Everything else is off-limits, and the exam tests these prohibitions hard:
- The notary must not ask questions, suggest answers, or coach the witness.
- The notary must not interpret, summarize, or characterize the testimony.
- The notary must not give legal advice to the deponent or any party.
- The notary must remain impartial throughout.
In practice a court reporter records and transcribes the testimony; the notary's act is often just swearing in the deponent. (In many jurisdictions the court reporter is themselves a notary, which is why the two roles blur.)
The Disqualifying-Interest Rule
A notary may not administer the oath or notarize the statement when the notary has a personal or financial interest in the matter, or is a party to the underlying case. A notary who is the plaintiff, a relative of a party, or stands to gain financially must decline. This is the single most common deposition/affidavit trap: impartiality is not optional.
Worked Scenario
A paralegal asks a notary to swear in a witness for a deposition and, during a pause, to "just clarify what the witness meant." The notary administers the oath correctly but refuses to clarify, paraphrase, or coach — doing so would breach impartiality and could taint the testimony. The notary's job ended at the oath (and, if authorized, certifying the record).
Key Principles for Both Acts
- Oath is mandatory — both affidavits and depositions require it; the oath, not the signature, is the controlling element.
- Impartiality is paramount — no coaching, no advice, no personal stake.
- No unauthorized practice of law — a notary cannot advise an affiant or deponent on legal rights or which form to use.
- Journal the act — record it like any notarization.
- Perjury is the enforcement mechanism — a knowingly false sworn statement is a crime, which is why the proper oath matters.
Common Traps
- Treating an affidavit as an acknowledgment — affidavits are jurats with an oath, not acknowledgments.
- Letting the affiant pre-sign — the oath and signing must occur before the notary.
- Coaching or summarizing in a deposition — strictly prohibited.
- Notarizing despite a personal interest — disqualifying.
- Refusing to offer an affirmation — improper; an affirmation equals an oath.
Quick Reference: Affidavit vs. Deposition
| Affidavit | Deposition | |
|---|---|---|
| Form | Written sworn statement | Oral sworn testimony |
| Notarial act | Jurat | Administer oath (and certify record if authorized) |
| Signing in presence | Required | N/A — testimony is spoken |
| Notary may question/coach | No | No |
| Recorded by | The affiant signs; notary completes jurat | Court reporter transcribes |
A reliable mental model: with an affidavit the notary completes the whole notarial act (oath + signature + jurat certificate), while at a deposition the notary supplies only the oath and steps back so the reporter and attorneys run the proceeding. Whenever a deposition question hands the notary a substantive task — clarifying, summarizing, advising, questioning — the answer is to decline. Whenever an affidavit question omits the oath, the act is incomplete and invalid as a jurat.
A notary is asked to notarize an affidavit. Which sequence reflects the correct act?
Identify the affiant, administer an oath or affirmation, watch the affiant sign in the notary's presence, then complete a jurat
Have the affiant acknowledge a pre-signed document and complete an acknowledgment certificate
Witness the signature only, with no oath
Compare the affidavit to an original and certify the copy
During a deposition, a party asks the notary to clarify a confusing answer for the record. The notary should:
Restate the answer in clearer words to help the record
Ask the deponent a follow-up question
Advise the deponent on how to answer
Decline, because the notary's role is limited to administering the oath and remaining impartial
A notary is also the plaintiff in a lawsuit and is asked to administer the oath at a deposition for that same case. The notary must:
Proceed, since administering an oath is a neutral act
Proceed but waive the journal entry
Proceed only if the deponent consents
Decline because of a disqualifying personal interest in the matter
