Affidavits and declarations: Essential legal distinctions

Meta Description:

Understand the critical differences between an affidavit and a declaration in the U.S. legal system. Learn when to use each document, the requirement for a notary, and how they function as sworn evidence in court proceedings, including Legal Forms and Affidavits.

Understanding the Difference: Affidavit vs. Declaration in U.S. Law

In the world of legal procedures, evidence often takes the form of sworn written statements. Two of the most common—and often confused—documents are the affidavit and the declaration. While both serve as a means of providing testimony outside of a courtroom, their key differences lie in the formal requirements for their execution and the legal authority that governs their use. Understanding these distinctions is crucial for anyone involved in Legal Procedures, from Filing & Motions to preparing for Trials & Hearings.

💡 Legal Expert Tip: The Power of Sworn Testimony

Both affidavits and declarations are powerful because the person signing them is attesting to the truth of the facts under penalty of perjury. This means a deliberately false statement could lead to criminal charges for Fraud or other serious consequences, making the documents reliable forms of written evidence.

What is an Affidavit? The Traditional Standard

An affidavit is a formal, voluntary, sworn statement of fact, confirmed by an oath or affirmation before a person legally authorized to administer one—typically a notary public. This notarization step is the hallmark of the affidavit and a core element of its admissibility in various Case Types.

Formal Requirement: Requires the signature of a notary public or another officer (like a judge or court clerk) to confirm the identity of the signer and that the oath was properly administered.
Authority: Rooted in common law tradition and is often explicitly required by specific court rules or Statutes & Codes.
Usage: Very common in Property disputes, certain types of Civil cases, and situations where the highest level of formality and authentication is necessary (e.g., executing certain Wills or submitting evidence in Federal Courts).

⚠️ Caution: The Notary is Non-Negotiable

If a legal rule or statute specifically requires an “affidavit,” a declaration, no matter how carefully worded, will likely be rejected. The act of notarization is what distinguishes it.

What is a Declaration? The Modern Alternative

A declaration is a written statement signed by the declarant, certifying or declaring under penalty of perjury that the contents are true and correct. Crucially, a declaration does not require a notary public.

The use of declarations has largely been established to simplify the process of submitting evidence and reduce the administrative burden of finding a notary. This procedure is codified, primarily at the federal level by 28 U.S.C. § 1746, which allows a declaration to substitute for an affidavit in federal proceedings if the statement includes specific language:

“I declare (or certify, verify, or state) under penalty of perjury that the foregoing is true and correct. Executed on (date). (Signature).”

Comparison: Affidavit vs. Declaration
Feature	Affidavit	Declaration
Notary Requirement	Yes (Oath administered)	No (Self-certifying)
Governing Law	Common Law, State/Federal Rules	28 U.S.C. § 1746 (Federal), State Statutes
Key Phrase	“Subscribed and sworn to before me…”	“Under penalty of perjury…”

When to Choose Which Document

The choice between an affidavit and a declaration generally depends on the jurisdiction and the specific document being filed. When preparing Legal Forms or Affidavits:

■ Use a Declaration When:

You are filing in Federal Courts (where 28 U.S.C. § 1746 applies) or in a state that has adopted a similar statute allowing declarations in lieu of affidavits. This is the preferred method for many routine Motions and filings because of its simplicity.

■ Use an Affidavit When:

A statute, court rule (especially in state or local courts), or a third party (like a bank or government agency) explicitly requires a notarized sworn statement. Certain specialized procedures, such as those related to a POA (Power of Attorney) or certain types of recorded documents, often still mandate a formal affidavit.

Summary of Key Takeaways

The primary difference is the notary public requirement: Affidavits require one, declarations do not.
Both documents carry the weight of being sworn evidence, subjecting the signer to the penalty of perjury for false statements.
Federal law (28 U.S.C. § 1746) generally permits a declaration to substitute for an affidavit in federal proceedings.
Always check the specific court rules for the relevant State Courts or the requirements for the Case Types you are dealing with before choosing your document.
When in doubt, and if time/cost permits, an affidavit is almost always legally sufficient where a declaration would be accepted, but the reverse is not true.

📜 At a Glance: Evidence & Procedure

Affidavits and declarations are foundational documents used in nearly every phase of litigation, from the initial Petitions to supporting Appeals. They transform verbal statements into admissible written evidence, streamlining the process of proving facts without live testimony. Proper preparation of these Legal Forms is a critical step in effective case management.

Frequently Asked Questions (FAQ)

Q1: Can a declaration be used in all state courts?

No. While many states have adopted similar statutes to the federal law allowing declarations, some State Courts still mandate a notarized affidavit for specific filings. Always consult the Court Rules for the relevant jurisdiction.

Q2: What is the penalty for lying in an affidavit or declaration?

Lying in either document constitutes perjury, which is a serious crime that can result in fines, imprisonment, and significant damage to the credibility of your Case Law or claim.

Q3: If I am outside the U.S., how do I get an affidavit notarized?

The federal statute allows declarations to be used even when signed outside the U.S. if signed “under penalty of perjury.” For affidavits, notarization may be done by a U.S. consular officer or by a foreign notary whose authority is certified via an Apostille or similar diplomatic authentication, depending on the treaty status of the country.

Q4: Are “Affidavits” and “Sworn Statements” the same thing?

An affidavit is a specific type of sworn statement. A declaration is also a sworn statement (sworn under penalty of perjury). The term “sworn statement” is a broader category that covers both.
