Sample affidavit: witness of couple living separately under the same roof


An affidavit by another person, who is not your spouse, serves to confirm your story that you have lived separately under the same roof.

This person could be a family member, friend, neighbour or professional who is familiar with the circumstances of your relationship and is over 18.


What should the witness include in an affidavit?

Generally, an affidavit should not set out the opinion of the person making the affidavit; that is, it must be based on facts not their beliefs or views.

Where possible you should avoid referring to facts that are based on information received from others (known as hearsay evidence).

You should not include in your affidavit, what you think another person was feeling or thinking unless you have evidence of them telling you what they thought or felt at the time, such as a one on one conversation, letter or email.

Any affidavit you file must be served on all parties. Read more about serving documents: Serving divorce papers: A quick how to guide


Formatting an affidavit

The affidavit must be divided into paragraphs. Each paragraph must deal with only one aspect of the subject matter. It is suggested that each paragraph contain no more than about 6 lines.

  • Each paragraph must be numbered.

  • Each paragraph should be confined to a distinct part of the subject matter.

  • The affidavit must be typed. Handwritten affidavits will be accepted only in circumstances of urgency, usually involving some immediate threat of harm to a child.

  • Text should be printed on only one side of white A4 paper.

  • Documents in support of your affidavit should be referenced as an annexure in the format required by the appropriate court (see below).

  • The address for service of the documents (the address the court can contact the deponent) must be included in the footer of page 1.



Their affidavit should be formatted in the same way as the sample below:

  8. Anything else that is evidence the two parties have lived separately under the same roof and have not been in a marriage relationship.

End of Affidavit


Attach supporting documents:

If you have any evidence that supports the information you have written in your affidavit, you should attach them to your affidavit. For example, an email, screenshot of a text or letter you sent your spouse about your separation and subsequent arrangements, a letter from Centrelink confirming your change of relationship status.

You should check the website of the court you are filing in to confirm how it requests supporting evidence to be filed.

Generally, to attach a document, for example a letter, you should write in the affidavit: "annexed to this affidavit and marked "A" is a copy of the letter ". You should then write "A" at the top of the front page of the letter you are attaching.

On the first page of each annexure, you should include the parties to the matter, the file number and the words,

“This is the annexure marked with the letter “A” referred to in the Affidavit of deponent’s name affirmed XDay of XMonth 20XX before me:

Below this phrase is where the authorised person should sign that they have witnessed.

The deponent must also sign each page of the document.

If you have more than one document, mark each one A, B, C, D etc. in the order that you refer to them in your affidavit and attach them in that order to the back of your affidavit.

Attaching documents

Federal Circuit Court

If you refer to a document in your affidavit, you must attach a copy of it to the back of your affidavit (known as an annexure). Examples of an annexure are a contract of sale or a child’s school report. If there is more than one annexure, you need to refer to each one by a number or letter; for example, Annexure 1 or Annexure A. You also need to number the annexures consecutively, that is, from the first page of the first annexure to the last page of the last annexure. Each annexure must have a statement signed by the authorised person identifying the annexure as the document referred to in the affidavit.

The wording of the statement is:

This is the document referred to as Annexure [insert reference number] in the affidavit of [insert deponent’s name], sworn/affirmed at [insert place] on [insert date] before me [authorised person to sign and provide name and qualification].

The statement must be signed at the same time as the affidavit and by the same authorised person.

Family Court

A document that is to be used in conjunction with an affidavit and tendered in evidence in a court proceeding, must be identified in the affidavit but must not be attached to (or annexed to) the affidavit, or filed as an exhibit to the affidavit. There may be exceptions where court orders or the Rules provide otherwise (for example Family Law Rule 15.62 in relation to expert reports). The document/s referred to in the affidavit must be served with the affidavit on the other party/ies after filing and referenced in the disclosure list. The document/s must then be tendered in evidence at the court event when the relevant affidavit is relied upon or as required. See Family Law Rule 15.08. Source: Family Court of Australia.


Signing an affidavit

The person making an affidavit (the deponent) must sign the bottom of each page in the presence of an authorised person, such as a lawyer (as long as they have not participated in preparing the affidavit or in the proceedings in which the affidavit is intended to be used), or Justice of the Peace.

If you are overseas a Notary Public or Australian Diplomatic/Consulate Officer can witness the signature.

On the last page of the affidavit the following details must be set out (known as a jurat):

  • the full name of the person making the affidavit, and their signature

  • whether the affidavit is sworn or affirmed

  • the day and place the person signs the affidavit, and

  • the full name and occupation of the authorised person, and their signature.

If any alterations (such as corrections, cross-outs or additions) are made to the affidavit, the person making the affidavit and the witness must initial each alteration.
