An affidavit is a written statement of facts that you swear or affirm to be true, signed in front of a notary or other authorized official. Affidavits are used everywhere — courts, banks, schools, immigration matters, and everyday business — because they put a person’s statement on the record under oath. This article explains what an affidavit is, what it contains, the common types, and how to get one notarized online in minutes.
The definition in plain terms
At its core, an affidavit is a sworn statement. The person making it, called the affiant, declares that the facts in the document are true to the best of their knowledge, and signs it in the presence of a notary who administers an oath or affirmation. That oath is what separates an affidavit from an ordinary letter: by signing it, the affiant accepts legal responsibility for the truth of the statement, and a false affidavit can carry serious consequences.
What an affidavit includes
- A title identifying the document as an affidavit.
- The affiant’s name and a statement that they are of legal age and competent to testify.
- The facts being sworn to, usually in numbered paragraphs.
- A statement that the facts are true to the best of the affiant’s knowledge.
- A signature line for the affiant and a notarial certificate (a jurat) for the notary.
Affidavit vs. a regular statement
A regular statement or letter simply communicates information. An affidavit elevates that information into sworn testimony. The difference matters because courts, agencies, and institutions can rely on an affidavit as evidence. That is also why an affidavit almost always requires notarization with a jurat — the notarial act in which the affiant swears the contents are true and signs in front of the notary.
Common types of affidavits
- Affidavit of identity, confirming who you are.
- Affidavit of residence, confirming where you live.
- Financial affidavit, stating income, assets, or support.
- Affidavit of support, often used in immigration matters.
- Small estate affidavit, used to transfer a modest estate without full probate.
Why affidavits must be notarized
Notarization is what gives an affidavit its weight. The notary verifies the affiant’s identity, administers the oath, and witnesses the signature, then completes a jurat certificate. The distinction between a jurat and an acknowledgment is important here, and the National Notary Association explains it clearly: an affidavit uses a jurat because the affiant is swearing to the truth of the contents, not merely acknowledging a signature.
Affidavit vs. declaration
A close cousin of the affidavit is the declaration. Both contain statements of fact, but a declaration is typically signed “under penalty of perjury” without a notary, while an affidavit is sworn before a notary who completes a jurat. Some courts and agencies accept either, while others specifically require a notarized affidavit. Because the difference affects whether you need a notary at all, check which one the receiving party requires before you prepare your document. When notarization is required, the affidavit route is the one this guide focuses on.
Where affidavits show up in everyday life
Affidavits are not just for lawyers. Parents use them to confirm a child’s residence for school enrollment, families use small estate affidavits to settle modest estates without full probate, and individuals use affidavits of identity when records list slightly different versions of their name. Businesses use affidavits to certify facts for transactions, and people in immigration matters frequently submit affidavits of support. In each case, the affidavit lets a person put facts on the record in a form an institution can trust and act on.
How to get an affidavit notarized online
Because affidavits are so common and often needed quickly, online notarization is a natural fit. You upload your completed affidavit, verify your identity, and join a recorded video session with a commissioned notary who administers the oath and witnesses your signature. The notary applies the jurat and electronic seal, and you download a finished, tamper-evident document. For a full walkthrough of the technology, see our overview of online notarization.
Writing a strong affidavit
A good affidavit is clear, factual, and specific. Stick to facts you personally know, use plain language, and organize statements in numbered paragraphs so each fact stands on its own. Avoid opinions, speculation, or argument — an affidavit is testimony, not persuasion. Leave the signature and notarial sections blank until your session, because you must sign in front of the notary for the jurat to be valid.
What you need to notarize online
- A valid, unexpired government-issued photo ID.
- A device with a camera and microphone, and a stable internet connection.
- Your completed affidavit, unsigned.
- Your personal information for knowledge-based authentication.
Common mistakes to avoid
The most frequent errors are signing the affidavit before the session, including opinions instead of facts, and using a certificate meant for an acknowledgment rather than a jurat. Each can cause the document to be rejected. Read the affidavit carefully, make sure it has the correct jurat wording, and wait to sign until the notary is watching.
A simple affidavit structure to follow
If you are drafting your own affidavit, a reliable structure is: a heading naming the document and the affiant; an opening line such as “I, [name], being duly sworn, state as follows”; numbered factual statements; a closing line affirming the facts are true to the best of your knowledge; and then the signature line and jurat. Keeping the facts in separate numbered paragraphs makes the affidavit easy to read and easy for a court or agency to reference, and it helps you confirm that each statement is something you genuinely know to be true.
How long does it take?
The drafting is usually the longest part; the notarization itself is fast. Online, the recorded session typically takes only a few minutes, and including identity verification most appointments finish well under half an hour. Because online notaries are frequently available evenings and weekends, an affidavit needed on short notice can often be completed the same day — a real advantage when a filing deadline is approaching.
Do affidavits need witnesses?
Most affidavits require only the affiant and the notary, but some documents or jurisdictions call for one or more witnesses in addition to the notarial act. If your affidavit indicates a witness is required, a qualified witness can usually join the same online session, so you can satisfy both requirements at once. When you are unsure, check the document’s instructions or ask the receiving party before you schedule.
Affidavits for international use
If your affidavit will be used in another country, notarization may be only the first step. Many international documents also need an apostille or authentication, which is issued separately by the state and follows the notary’s commissioning state. Plan for that extra step and start early, because the authentication can take longer than the notarization itself.
After your affidavit is notarized
You receive a sealed PDF carrying the jurat and electronic seal, ready to file or submit. Because the file is tamper-evident, any later change is detectable. Keep your own copy, and confirm with the receiving party — a court, agency, or institution — that they accept an electronically notarized affidavit, since a small number still require paper originals.
Frequently Asked Questions
What is an affidavit?
An affidavit is a written statement of facts that the maker, called the affiant, swears or affirms to be true and signs in front of a notary. The notary administers an oath and completes a jurat, which is what allows courts, agencies, and institutions to rely on the affidavit as sworn testimony.
Does an affidavit have to be notarized?
In nearly all cases, yes. An affidavit’s value comes from being sworn before a notary, who verifies identity, administers the oath, and witnesses the signature using a jurat. Without notarization, the document is just an unsworn statement and generally will not be accepted as an affidavit.
Can I get an affidavit notarized online?
Yes, in states that permit remote online notarization, or through an out-of-state online notary your recipient accepts. You upload the completed affidavit, verify your identity, and a commissioned notary administers the oath and witnesses your signature over a recorded video session.
What is the difference between an affidavit’s jurat and an acknowledgment?
A jurat is used for affidavits and sworn statements: the affiant swears the contents are true and signs in front of the notary. An acknowledgment, used for contracts and deeds, only confirms identity and willingness to sign. The certificate wording on your document indicates which act applies.
