Statutory declaration

Key takeaways

Statutory declaration belongs to science; place it in that map before memorising details.

Reference excerpt

A statutory declaration is a legal document defined under the law of certain Commonwealth nations and in the United States. It is similar to a statement made under oath, but it is not sworn. Statutory declarations are commonly used to allow a person to declare something to be true for the purposes of satisfying some legal requirement or regulation when no other evidence is available. They are thus similar to affidavits, which, however, are made on oath. Depending on jurisdiction, statutory declarations can be used for:

Declarations of identity, nationality, marital status, etc. when documentary evidence is unavailable. Declaring the intention to change one's name. Affirming the provenance and nature of goods for export or import. Statements of originality for patent applications.

Australia Australian law defines a statutory declaration as a written statement declared to be true in the presence of an authorised witness. The Statutory Declarations Act 1959 governs the use of statutory declarations in matters involving the law of the Australian Commonwealth, Australian Capital Territory, and other territories but not including the Northern Territory. Any person within the jurisdiction of this law may make a statutory declaration in relation to any matter. The declaration may be used in connection with matters of law, including judicial proceedings, but what weight is given to the declaration is a matter for the judge to decide. Statutory declarations must be made in a prescribed form and witnessed by a person as specified in the Statutory Declarations Regulations 2023. Prescribed witnesses include people on the roll of the High Court or the Supreme Court of a State or Territory, legal or medical practitioners, justices of the peace, notaries public, police officers, military officers, registered members of certain professional organisations (e.g. National Tax Accountant's Association or Engineers Australia), and certain other Commonwealth employees. Intentionally making a false statement as a statutory declaration is a crime equivalent to perjury, and punishable by fines and/or a prison sentence of up to four years. The states and territories of Australia each have their own laws regarding statutory declarations.

Canada In Canadian jurisdictions, statutory declarations are statements of facts written down and attested to by the declarant before individuals who are authorized to administer oaths except that they are normally used outside of court settings. They have the same effect in law as a sworn statement or affidavit. In federal proceedings, the form is governed by the Canada Evidence Act. Similar provision is made by the various provinces for use in proceedings within their respective jurisdictions. A person who makes a false declaration can be charged with perjury under the Criminal Code.

United States Although the terminology statutory declaration is not used frequently in the United States, unsworn declarations may invoke a statute that makes such a declaration the functional equivalent of a sworn affidavit.

United Kingdom Statutory declarations can be used as a method of legally changing one's name. They may be used by UK financial institutions to enable an asset of a relatively small value (usually less than £15,000) to be transferred to the executors of a will or other persons legally entitled to deal with or benefit from the estate of a person who has died.

England and Wales

Under the Statutory Declarations Act 1835 (5 & 6 Will. 4. c. 62), a declaration can be made before anyone who is authorised by law to hear it (for example, a solicitor or legal executive), or before any justice of the peace. In addition, officers of the armed services with the equivalent rank of major and above, and British diplomatic and consular officers in post abroad, may authenticate a statutory declaration. The person who hears the declaration need not enquire into the truth of it. That person's function is limited to hearing the declaration, and certifying that he or she has done so by signing it. If the declaration turns out to be untrue, the defendant making it may be punished for perjury. The form of the statutory declaration is prescribed in the schedule to the act:

I (full name), do solemnly and sincerely declare that the contents of this declaration are true. And I make this declaration conscientiously believing the same to be true and by virtue of the provisions of the Statutory Declarations Act 1835. A standard form is used for a statutory declaration; one copy will be given to the applicant and the other is held on file.

Worked examples

Example 1 — a first encounter with Statutory declaration

Start with the simplest possible case. Write down what Statutory declaration claims or describes in one sentence, then invent the smallest concrete situation in which that sentence is true. In science, the smallest case is usually a single object, a single equation or a single measurement. Check that every symbol or term in your sentence has a meaning in that case.

Example 2 — changing one variable

Take the situation from Example 1 and change exactly one quantity: double it, halve it, or set it to zero. Predict what should happen to Statutory declaration before you calculate. Comparing your prediction with the result is the fastest way to find out whether you understand the idea or only the words.

Example 3 — an exam-style question

Typical questions about Statutory declaration ask you to (a) state it precisely, (b) apply it to given data, and (c) explain a limitation. Practise writing all three answers in under five minutes; the third part is what separates a full-mark answer from an average one.

Applications of Statutory declaration

In research: Statutory declaration appears in science research whenever the underlying quantities have to be modelled precisely. Papers usually cite it as a starting assumption and then explore where it breaks down.
In technology and industry: Engineering practice reuses Statutory declaration in design rules, simulations and safety margins. Knowing the idea lets you read a specification sheet and understand why the numbers look the way they do.
In the classroom: Statutory declaration is common in secondary-school and first-year university syllabi. It links to neighbouring topics Evidence law, Law of Australia, Legal documents, so understanding it makes those chapters shorter.
In everyday life: Look for Statutory declaration outside the textbook — in sport, cooking, traffic, electronics or the sky above you. An example you found yourself is remembered far longer than one you were given.
