When a Statutory Declaration is required over an affidavit
Most Commonwealth-jurisdiction registrars and tribunals accept either an affidavit or a Statutory Declaration, but specific procedures demand one or the other. UK Home Office partner-visa applications under Appendix FM accept either form; UK Land Registry RX1 and TR1 transfers require a Statutory Declaration. Australian DHA partner visas (subclass 309/100, 820/801) require Statutory Declarations from sponsoring partner and supporting witnesses, on the Form 888 template. Australian probate (NSW, VIC, QLD) requires Statutory Declarations from the executor regarding asset values. New Zealand IRD tax-residency challenges, Auckland Council building-consent applications and most NZ probate matters use Statutory Declarations exclusively. Canadian Express Entry, study-permit and family-sponsorship applications accept either, but Quebec's MIFI requires the affidavit form. UK and Australian immigration tribunals occasionally specify 'Statutory Declaration in accordance with the [Act]' — using an affidavit when a Statutory Declaration is named will trigger a procedural defect notice.
Drafting structure mandated by each Commonwealth jurisdiction
- United Kingdom — Title 'STATUTORY DECLARATION', preamble 'I, [full name], of [address], do solemnly and sincerely declare that…', numbered paragraphs of fact, closing 'and I make this solemn declaration conscientiously believing the same to be true, and by virtue of the Statutory Declarations Act 1835', declared at [place] on [date], signature, jurat by Commissioner for Oaths or Notary Public.
- Australia — Schedule 1 form prescribed by regulation: 'I, [name], of [address], [occupation], make the following declaration under the Statutory Declarations Act 1959', numbered paragraphs, declaration clause 'I understand that a person who intentionally makes a false statement in a statutory declaration is guilty of an offence under section 11 of the Statutory Declarations Act 1959, and I believe that the statements in this declaration are true in every particular'.
- New Zealand — Five-paragraph standard: identification, statement of facts, the declarant's understanding of the Oaths and Declarations Act 1957 section 111 criminal penalty, signature line, jurat by JP / Solicitor / Notary / Court Registrar.
- Canada — Federal Form 21 or provincial Evidence Act form; must include 'I make this solemn declaration believing it to be true and knowing that it is of the same force and effect as if made under oath'.
Common use cases at our Bangkok office
Our notarial team takes approximately 130 Statutory Declarations per month, predominantly for Commonwealth-destined applications. The most common patterns are: (1) Form 888 declarations from third-party witnesses supporting Australian partner-visa applications — the declarant must be 18+, an Australian citizen or permanent resident, and personally know both parties; we handle the format and the chain of MFA + Australian Embassy authentication. (2) UK statutory declarations of name-change for British passport renewal where the holder married in Thailand and wants the married name on the passport; the declaration must reference the Thai marriage certificate (Kor Ror 2) and our chain of certified translation + MFA + UK Embassy is required. (3) NZ statutory declarations of cohabitation for de-facto partner visas — both partners declare separately, then both are MFA-legalized and stamped at the NZ Embassy. (4) Canadian Schedule A statutory declarations for sponsorship financial undertaking. (5) UK Land Registry RX1 statutory declarations for overseas-resident property owners.
Differences vs an affidavit, in plain language
- Wording — Statutory Declaration uses 'declare' or 'solemnly declare'; affidavit uses 'swear' and 'on oath' or 'on affirmation'.
- Legal source — Statutory Declarations rest on each Commonwealth jurisdiction's Statutory Declarations Act; affidavits rest on common-law oath procedure plus court-specific rules.
- Penalty — false statutory declaration is a criminal offence punishable by imprisonment (up to 7 years in UK, 4 years in AU, 3 years in NZ, 14 years in Canada for federal matters).
- Religious oath — affidavits historically required swearing on a religious text (Bible, Quran, etc.); Statutory Declarations have no religious element and are acceptable to declarants of any or no faith.
- Acceptable taker — affidavits in Thailand are taken by a Notarial Services Attorney; Statutory Declarations are taken by the same attorney but the recording form differs in the Notarial Register.
