If you’re involved in a family law matter in the Federal Circuit and Family Court of Australia, you may be required to file an affidavit.
An affidavit is a written statement of facts, sworn or affirmed to be true, and it’s one of the most important documents in your case.
At Barker Evans, we help clients prepare affidavits that are clear, persuasive, and compliant with court rules.
Here’s what you need to know to draft a good family law affidavit.
What is an Affidavit?
An affidavit is your evidence in written form. It sets out:
- Relevant facts of your case
- Details of events you witnessed or experienced
- Supporting evidence (such as documents or photos, attached as annexures)
Once filed, your affidavit is read by the judge and often by the other party.
This makes accuracy, clarity, and professionalism essential.
Why a Well-Drafted Affidavit Matters
A strong affidavit can:
- Help the judge quickly understand your side of the story
- Support your application or response
- Reduce the need for lengthy oral evidence in court
- Strengthen your credibility
A poorly prepared affidavit can have the opposite effect — confusing the court, weakening your case, or even excluding important evidence.
Key Steps to Drafting a Good Family Law Affidavit
1. Understand the Rules
Family law affidavits must comply with the Federal Circuit and Family Court Rules. This means:
- Using plain English
- Sticking to relevant facts
- Avoiding opinion, argument, or hearsay (unless permitted)
- Numbering each paragraph and page
- Including only evidence you have personal knowledge of
2. Start With the Most Important Facts
Judges are busy. Place your strongest and most relevant facts early in your affidavit.
Organise your information in a logical order — usually chronological or grouped by topic (e.g., parenting arrangements, financial matters).
3. Be Clear, Concise, and Specific
Avoid long, complicated sentences or emotional language.
Instead of:
“He is always late to pick up the children.”
Say:
“On 5 March 2024, the respondent arrived at 5:45pm to collect the children. The agreed time was 5:00pm.”
Specific details are more persuasive than general statements.
4. Support Your Facts With Evidence
If you refer to documents, photos, or messages, attach them as annexures.
Label them clearly (e.g., “Annexed hereto and marked Annexure A is a copy of a text message dated 5 March 2024”).
Always explain in the affidavit why the annexure is relevant.
5. Keep It Professional
Your affidavit should remain respectful, even when discussing difficult topics.
Avoid personal attacks or unnecessary details that could undermine your credibility.
6. Proofread and Check Compliance
Before signing, check that your affidavit:
- Is truthful and accurate
- Contains only relevant facts
- Follows the court’s format and page limits
- Is signed and witnessed correctly by an authorised person (e.g., lawyer or JP)
