DECLARATION
A declaration is a written statement submitted to a court in which the writer swears 'under penalty of perjury' that the contents are true. That is, the writer acknowledges that if he is lying, he may be prosecuted for perjury. Declarations are normally used in place of live testimony when the court is asked to rule on a motion.
A typical declaration sets forth the factual assertions of the person signing it (called the declarant) and ends with a statement worded like this one: 'I declare under penalty of perjury that the foregoing is true and correct, and would be my testimony if I were in a court of law.' The date and place of signing are usually included.
Some states allow declarations to be used in the place of affidavits, thus avoiding a trip to the notary public.
What Is the Legal Purpose of a Declaration?
In law, a declaration serves as a formal written statement made under oath, used to convey factual assertions that a party is prepared to testify to in court. Declarations are commonly submitted with motions or pleadings to support legal arguments when live testimony is impractical. Their primary purpose is to provide a verified narrative of facts based on the declarant's personal knowledge.
Declarations are typically used in civil cases, family law disputes, criminal defense motions, and probate matters. Courts rely on them to assess credibility and facts when making preliminary decisions, especially during pre-trial procedures such as summary judgment or restraining order applications.
What is Included in a Declaration?
A declaration is a specification, in a methodical and logical form, of the circumstances which constitute the plaintiff's cause of action. In real actions, it is most properly called the count; in a personal one, the declaration. The latter, however, is now the general term; being that commonly used when referring to real and personal actions without distinction.
The declaration in an action at law answers to the bill in chancery, the libel of the civilians, and the allegation of the ecclesiastical courts.
It may be considered with reference:
- To those general requisites or qualities which govern the whole declaration;
- To its form, particular parts, and requisites.
Common Types of Legal Declarations
Declarations come in various forms depending on their use in legal proceedings. Common types include:
- Sworn Declarations: Statements made under penalty of perjury, often used in lieu of affidavits in jurisdictions that permit this substitution.
- Statutory Declarations: Used for legal purposes such as affirming identity, residency, or certain facts required by governmental agencies.
- Probate Declarations: Statements used in estate administration, such as confirming relationships or disclosing assets.
- Declarations in Criminal Cases: May accompany motions to suppress evidence or challenge probable cause.
- Family Law Declarations: Often required in custody, divorce, or support proceedings to inform the court about personal situations and facts.
Each type must comply with jurisdictional rules regarding format and content.
Qualities of a Declaration
The general requisites or quali- ties of a declaration are first, that it correspond with the process. But, according to the present practice of the courts, oyer of the writ cannot be craved; and a variance between the writ and declaration cannot be pleaded in abatement.
Secondly. The second general requisite of a declaration is, that it contain a statement of all the facts necessary in point of law, to sustain the action, and no more.
- Thirdly. These circumstances must be stated with certainty and truth. The certainty necessary in a declaration is, to a certain intent in general, which should pervade the whole declaration, and is particularly required in setting forth: The parties; it must be stated with certainty who are the parties to the suit, and therefore a declaration by or against 'C D and Company,' not being a corporation, is insufficient.
- The time; in personal actions the declaration must, in general, state a time when every material or traversable fact happened; and when a venue is necessary, time must also, be mentioned. The precise time, however, is not material unless it constitutes a material part of the contract declared upon, or where the date, etc., of a written contract or record, is averred.
- Other circumstances necessary to maintain the action.
Best Practices for Writing a Legal Declaration
A well-crafted declaration can significantly impact a legal case. Consider the following best practices:
- Use First-Person Language: Write from the perspective of the declarant (e.g., "I saw..." or "I was present when...").
- Stick to Facts: Focus on specific, firsthand knowledge. Avoid hearsay, opinions, or assumptions.
- Be Clear and Concise: Courts value declarations that are direct and easy to follow.
- Include Dates and Times: Be as precise as possible when recounting events.
- Maintain Professional Tone: Avoid emotional or inflammatory language.
-
Ensure Proper Formatting:
- Begin with a caption that includes case details.
- Include a declaration under penalty of perjury (e.g., “I declare under penalty of perjury under the laws of [State] that the foregoing is true and correct.”).
- Sign and date the document.
Improper or vague declarations can weaken a case, so accuracy and clarity are essential.
Parts of a Declaration
The parts and particular requisites of a declaration are:
First. The Title of the court and term.
Second. The Venue. Immediately after the title of the declaration follows the statement in the margin of the venue, or county in which the facts are alleged to have occurred, and in which the cause is tried. See Venue.
Third. The Commencement. What is termed the commencement of the declaration follows the venue in the margin, and precedes the more circumstantial statement of the cause of action. It contains a statement:
- Of the names of the parties to the suit, and if they sue or be sued in another right, or in a political capacity, (as executors, assignees, qui lam, etc.) of the character or right in respect of which they are parties to the suit.
- Of the mode in which the defendant has been brought into court; and,
- A brief recital of the form of action to be proceeded in.
Fourth. The statement of the cause or action, in which all the requisites of certainty before mentioned must be observed, necessarily varies, according to the circumstances of each particular case, and the form of action, whether in assumpsit, debt, covenant, detinue, case, trover, replevin or trespass.
Fifth. The Several Counts. A declaration may consist of as many counts as the case requires, and the jury may assess entire or distinct damages on. all the counts and it is usual, particularly in actions of assumpsit, debt on simple contract, and actions on the case, to set forth the plaintiff's cause of action in various shapes in different counts, so that if the plaintiff fail in proof of one count, he may succeed in another.
Sixth. The Conclusion. In personal and mixed actions the declaration should conclude to the damage of the plaintiff unless in scire facias and in penal actions at the suit of a common informer.
Seventh. The Profert and Pledges. In an action at the suit of an executor or administrator, immediately after the conclusion to the damages, etc., and before the pledges, a profert of the letters testamentary or letters of administration should be made. At the end of the declaration, it is usual to add the plaintiff as common pledges to prosecute, John Doe and Richard Roe.
A declaration may be general or special; for example, in debt or bond, a declaration counting on the penal part only, is general; when it sets out both the penalty and the condition, and assigns the breach, it is special.
How a Declaration Differs from an Affidavit
Though similar in purpose, a declaration and an affidavit have key distinctions:
Feature | Declaration | Affidavit |
---|---|---|
Oath | Made under penalty of perjury, not notarized | Made under oath and notarized |
Format | Can be more informal depending on court rules | Must follow formal notarization rules |
Use | Often accepted in motion practice in state/federal court | Required for certain official documents and proceedings |
Convenience | Easier to draft and file without a notary | Requires appearance before a notary public |
Many jurisdictions allow declarations to replace affidavits to streamline court procedures, especially in civil and family courts.
