Quick Definition: What Is an Affidavit?

An affidavit is notarized when a notary public verifies the identity of the person making the statement, witnesses the signing of the document, and administers an oath or affirmation confirming the contents are true to the best of the signer’s knowledge.

If you have ever been handed an affidavit and told it needs to be notarized before you can submit it, the process can feel more complicated than it actually is. For individuals navigating a legal matter on their own, or for attorneys coordinating affidavit execution across multiple clients, understanding exactly what notarization involves and how to move through it efficiently can save a significant amount of time and confusion.

This guide walks through how to notarize an affidavit, covering what an affidavit is, why notarization matters, the step-by-step process, and how Remote Online Notarization (RON) can serve as a practical alternative to in-person appointments.

What Is an Affidavit?

An affidavit is a written statement made under oath. When someone signs an affidavit, they are swearing or affirming that the information it contains is true to the best of their knowledge, often under penalty of perjury depending on the jurisdiction and the document’s language. That distinction matters: an affidavit is not just a signed statement, it is a formal declaration with legal consequences if the information turns out to be false.

Affidavits come up across a wide range of legal and administrative contexts. Some of the more common types include:

• Affidavits of fact used in civil and criminal court proceedings
• Financial affidavits documenting income, expenses, and assets in family law or divorce cases
• Affidavits of identity or residency required by government agencies or financial institutions
• Affidavits supporting powers of attorney or estate matters
• Sworn statements used in insurance claims or dispute resolution

While the format and required content of an affidavit vary by jurisdiction and purpose, the core element is always the same: the person making the statement (called the affiant) is swearing under oath that what it says is accurate.

What Does It Mean to Notarize an Affidavit?

Notarizing an affidavit means a notary public verifies the identity of the person making the statement, witnesses the signing of the document, and administers an oath or affirmation confirming that the contents of the affidavit are true to the best of the affiant’s knowledge.

In most cases, affidavits are notarized using a jurat, which requires the signer to appear before the notary, sign the document in the notary’s presence, and take a sworn oath or affirmation about the accuracy of the statement. The notary then completes a notarial certificate, applies their official seal, and records the act according to applicable state requirements.

It is important to understand that a notary does not verify whether the information in the affidavit is actually true. Instead, the notary confirms the identity of the signer and records that the oath or affirmation took place. The legal responsibility for the accuracy of the statement remains with the person signing the affidavit.

Because notarization rules vary by state, the specific wording of the notarial certificate and the steps involved may differ depending on the jurisdiction where the affidavit is executed.

Why Does an Affidavit Need to Be Notarized?

Notarization adds a layer of verification and accountability to an affidavit. When a notary public witnesses the signing, they verify the affiant’s identity, confirm that the person is signing willingly and appears to understand what they are doing, and administer an oath or affirmation. The notary then completes a notarial certificate, adds their official seal, and records the act.

This process can add credibility to the affidavit. Courts, government agencies, and institutions that receive notarized affidavits have a formal record that the document was executed properly, which can make it harder to challenge the document’s authenticity later.

Whether notarization is strictly required depends on how the affidavit will be used and the rules of the jurisdiction involved. Court filings almost always require notarization. Government agency submissions, estate matters, and certain financial documents typically require it as well. For legal professionals coordinating affidavit execution, confirming the specific notarization requirements of the receiving court or agency before proceeding is always advisable.

Quick Overview How to notarize an affidavit typically involves five steps: preparing the affidavit, meeting with a notary public, verifying the signer’s identity, signing the document in the notary’s presence, and taking a sworn oath confirming the statement is true. The notary then completes a jurat certificate and applies their official seal. In many states, this process can be completed either in person or through Remote Online Notarization (RON), depending on local law.

How to Notarize an Affidavit: Step by Step

Step 1: Prepare the Affidavit

Before meeting with a notary, make sure the affidavit is fully drafted and complete. All required fields should be filled in, and the document should be clearly written or typed. One important rule: do not sign the affidavit in advance. Because affidavits are typically notarized using a jurat, the notary must witness the actual signing and administer an oath or affirmation. Bring the document unsigned to your appointment.

If you are unsure whether your affidavit is correctly formatted for its intended purpose, consulting an attorney before proceeding is a sensible step. Notaries cannot review the legal sufficiency of a document or advise on its content; they are there to witness the signing and verify identity only.

Step 2: Locate a Notary Public

Notary services are available through a variety of sources, including banks and credit unions (often free for account holders), law offices, shipping and print centers like UPS Store or FedEx Office, local government offices, and some public libraries. Mobile notaries are also available in many areas and can travel to a location that is convenient for the signer.

For individuals or law firms looking for a faster or more flexible option, Remote Online Notarization (RON) platforms can connect signers with commissioned notaries via live video session, often with same-day or flexible scheduling. RON availability depends on state law, which is covered in more detail below.

Step 3: Bring Valid Identification

The notary will need to verify your identity before the notarization can proceed. A current, government-issued photo ID is typically required, such as a driver’s license, state ID card, or passport. Make sure the name on your identification matches the name as it appears on the affidavit. Some states may have specific requirements about acceptable forms of ID, so it is worth confirming with the notary if you have any questions in advance.

Step 4: Sign the Affidavit in the Notary’s Presence

Once the notary has verified your identity, you will sign the affidavit while they watch. In most cases, the notary will also administer an oath or affirmation, asking you to swear or affirm that the contents of the affidavit are true. This step is what distinguishes a jurat, the standard notarial act for affidavits, from other types of notarization.

No one else may sign on your behalf during this step, and the notary may not sign until they have witnessed the signature firsthand.

Step 5: The Notary Completes the Certificate

After witnessing the signature and administering the oath, the notary completes the notarial certificate, adds their official signature and seal, and may record the act in their official notary journal depending on state requirements. At that point, the affidavit is typically considered notarized and may be submitted to the relevant court, agency, or institution.

Note: Most affidavits are notarized using a jurat, a notarial act that requires the signer to take an oath and sign in the notary’s presence. Some affidavits may call for a different type of notarization depending on the jurisdiction or the specific requirements of the receiving party. If you are unsure which notarial act applies to your affidavit, check with the requesting party or consult an attorney.

Notarizing an Affidavit Online Through Remote Online Notarization (RON)

Remote Online Notarization (RON) allows the affidavit notarization process to take place through a secure audio-visual platform rather than in person. The affiant connects with a commissioned online notary via live video, completes identity verification, signs the affidavit electronically while the notary watches, takes the required oath, and receives a digitally sealed copy of the completed document.

For individuals who have difficulty traveling, live far from available notary services, or need to complete time-sensitive documents outside of regular business hours, RON can be a practical option. For law firms managing affidavit execution across a client base in multiple locations, RON platforms can also streamline coordination by eliminating the need to schedule in-person appointments at each location.

To participate in a RON session, signers typically need a computer or laptop with a webcam and audio capability, such as a laptop or desktop computer, along with a reliable internet connection and a valid government-issued photo ID. Some platforms may have specific device or browser requirements, so it is worth confirming those details before the session.

The identity verification process in a RON session typically involves credential analysis (reviewing the security features of a government-issued ID), Knowledge-Based Authentication (KBA) (answering personal questions drawn from public records), and live verification by the notary during the video session. Together, these layers can help create a detailed verification process that documents the signer’s identity in detail.

Note: RON laws vary significantly from state to state. Some states have established comprehensive frameworks that permit remote online notarization for affidavits and other legal documents, while others may have restrictions or are still developing their regulatory frameworks. Before using RON to notarize an affidavit, verify that it is authorized in your state and that the receiving court or agency will accept it. Consulting an attorney familiar with notarization law in your jurisdiction is advisable, particularly when the affidavit will be used in formal legal proceedings.

Practical Notes for Law Firms Coordinating Affidavit Notarization

For legal professionals, the logistics of affidavit notarization can add meaningful friction to case preparation, particularly when clients are geographically dispersed, elderly, or managing health limitations that make in-person appointments difficult.

RON platforms may offer a practical solution for routine affidavit execution when permitted by applicable state law and accepted by the receiving court or agency. Before incorporating RON into a firm’s workflow, it is worth reviewing the specific notarization requirements of the courts and agencies where affidavits will be submitted, as acceptance of electronically notarized documents can vary.

A few other considerations for legal professionals:

• Confirm the correct notarial act for each affidavit. Most will require a jurat, but this can vary by jurisdiction and document type.
• Ensure the affidavit format complies with the requirements of the receiving court or agency before notarization takes place. A properly notarized document with deficient content may still be rejected.
• When using RON for client affidavits, walk clients through what to expect before their session, including equipment needs and the identity verification steps. This can reduce delays caused by technical confusion at the time of signing.
• Retain records of notarized affidavits and, where RON is used, the associated audit trail and session record. These can be valuable if the affidavit’s authenticity is later questioned.

Frequently Asked Questions

Does every affidavit need to be notarized?

Whether an affidavit requires notarization depends on how it will be used and the rules of the relevant jurisdiction or institution. Court filings almost always require notarization, as do many government agency submissions, estate-related affidavits, and certain financial documents. In some limited contexts, an unnotarized sworn statement may be accepted, but this is the exception rather than the rule. If you are unsure whether your affidavit needs to be notarized for a specific purpose, checking with the requesting party or consulting an attorney is the most reliable way to confirm requirements before proceeding.

Can I sign the affidavit before meeting with the notary?

Generally, no. An affidavit is typically notarized using a jurat, which requires the signer to sign in the notary’s presence and take a sworn oath at the time of signing. If you have already signed the affidavit before your appointment, the notary may not be able to complete the notarization. It is best to bring the affidavit unsigned and complete the signing during the session after the notary has verified your identity. If you are unsure about the requirements for your specific situation, confirming with the notary or your attorney in advance can prevent unnecessary delays.

What type of notarization does an affidavit require?

Most affidavits are notarized using a jurat, a notarial act that requires the signer to take a sworn oath or affirmation and sign in the notary’s presence. This is distinct from an acknowledgment, which confirms that the signer appeared before the notary and signed voluntarily but does not require an oath about the document’s contents. Because affidavits involve sworn statements about the truthfulness of information, the jurat is typically the appropriate notarial act. However, requirements can vary by jurisdiction and document type, so when in doubt, checking with the requesting court, agency, or an attorney is advisable.

Can an affidavit be notarized online?

In many states, yes. Remote Online Notarization (RON) platforms allow signers to complete affidavit notarizations through a secure live video session with a commissioned online notary. The process often includes multi-step identity verification, electronic signing in the notary’s presence, and administration of the required oath or affirmation, followed by the notary applying a digital seal and signature. To participate, signers typically need a computer or laptop with a webcam and microphone and a stable internet connection. RON laws and the acceptance of electronically notarized affidavits vary by state and by the receiving court or agency, so verifying requirements before scheduling a RON session is important.

What should I bring to an affidavit notarization appointment?

For an in-person appointment, bring the unsigned affidavit and a valid, government-issued photo ID, such as a driver’s license, state ID card, or passport. The name on your ID should match the name as it appears on the affidavit. Some notaries may also require payment for their services, though fees vary by location. If you are completing the notarization online through a RON platform, make sure your computer or laptop has a working webcam and microphone and that you have a stable internet connection. Having your ID readily available for the camera is also important, as identity verification is a required part of the RON process.

Conclusion

Knowing how to notarize an affidavit can make a meaningful difference when legal deadlines are involved and the stakes can be high. The process itself is generally straightforward: prepare the document, find a qualified notary, bring valid identification, sign in the notary’s presence, take the required oath, and receive your notarized copy. The key is understanding the requirements ahead of time so that the notarization goes smoothly and the document is accepted by the intended recipient.

For individuals navigating the process alone, Remote Online Notarization may offer a convenient path forward, particularly when in-person appointments are not practical. For law firms, RON can streamline affidavit execution across a geographically dispersed client base, provided the relevant jurisdictions and receiving institutions permit it.

Because notarization requirements vary by state, by document type, and by the court or agency involved, consulting an attorney when the affidavit will play a significant role in legal proceedings is always a sound step. Getting the notarization right the first time is considerably less complicated than addressing a rejected document under deadline pressure.
