How to Structure an Affidavit Before Swearing It

An affidavit is a written statement of fact that its author swears or affirms is true, before someone authorised to administer that oath. Until it’s sworn, it’s a draft — and the structure it needs is quite specific.
This describes the general shape. The wording, who may witness it, and whether your jurisdiction uses affidavits at all rather than statements of truth are questions for a lawyer where you are.
What the document contains
A heading identifying the court or matter, where there is one.
Deponent identification. Full name, address or occupation, and the capacity in which they swear — personally, or as a director of a company, or as a litigation friend. Capacity matters because it establishes why this person’s knowledge is relevant.
Numbered paragraphs of fact. One fact per paragraph, first person, chronological. Numbering isn’t decoration: it lets other documents and cross-examination refer to a specific statement precisely.
A statement of truth, in whatever wording the jurisdiction requires.
A jurat block — the section recording where and when it was sworn, before whom, and their capacity. This is what converts the document from a draft into an affidavit, and it’s completed by the person administering the oath, not by you.
Exhibits, where documents are referred to, each marked and referenced from the relevant paragraph.
What belongs in the paragraphs
Facts within the deponent’s own knowledge. That constraint does most of the work.
Include: what you saw, heard, did, or received directly. Dates. Documents you can exhibit.
Generally exclude: opinion, argument, and hearsay — what someone told you happened. Rules on hearsay vary and there are exceptions, but as a drafting default, if you didn’t witness it, be explicit about how you know it.
The distinction that trips people is between fact and characterisation. “The delivery arrived on 14 March” is a fact. “The supplier was persistently unreliable” is a conclusion, and a conclusion in an affidavit invites the whole document to be challenged.
State the facts and let them carry the conclusion.
| Paragraph content | Include? |
|---|---|
| What you directly observed | Yes |
| Dates, amounts, document references | Yes |
| What someone told you | Only with the source stated |
| Your opinion of someone’s conduct | No |
| Legal argument | No — that belongs elsewhere |
Why it isn’t valid until sworn
The document takes effect when the deponent swears or affirms before an authorised person — a commissioner for oaths, a notary, a solicitor, or an equivalent, depending on jurisdiction.
That person verifies identity, administers the oath or affirmation, and completes the jurat. An unsworn affidavit has no standing, and a swearing that doesn’t follow local requirements can invalidate it entirely.
Some jurisdictions have largely replaced affidavits with statements of truth, which are signed rather than sworn but carry contempt of court consequences if false. Knowing which applies is a threshold question rather than a detail.
Common mistakes to avoid
- Including argument or characterisation among the facts.
- Referring to a document without exhibiting it properly.
- Combining several facts into one paragraph, which makes precise reference impossible.
- Signing the jurat yourself, which is for the person administering the oath.
- Using a template from another jurisdiction, where the required wording differs.
How to do it with Affidavit Template Builder
The Affidavit Template Builder produces a draft with the standard structure.
- Identify the deponent and the capacity in which they swear.
- Write each fact as its own numbered paragraph, in the first person.
- Reference and mark any exhibits.
- Take the draft to a lawyer, then swear it before an authorised person.

Frequently asked questions
Is a generated affidavit legally valid?
Not as generated. An affidavit takes effect when sworn or affirmed before a person authorised in that jurisdiction. The document is a draft until then.
What belongs in the numbered paragraphs?
Facts within the deponent’s own knowledge, one per paragraph, in plain chronological language. Opinion, argument and hearsay generally don’t belong, and including them invites challenge.
Does the format vary by country?
Considerably. The heading, statement of truth wording, jurat, and who may administer the oath all differ — and some places use a statement of truth instead of a sworn affidavit entirely.
Final thought
Write only what you personally know, one fact per paragraph, and let a lawyer check it against local requirements. The structure is the easy part; the wording is jurisdictional.
