What Form B5 is for
Rule 2.06 of the Federal Court (Bankruptcy) Rules 2016 sets out what a person must do to oppose an application, interim application or petition (such as a creditor's petition) in a bankruptcy proceeding in the Federal Court. At least 3 days before the hearing, or at the hearing with the Court's leave, the person must file a notice of appearance (Form B4), file a notice in accordance with Form B5 stating the grounds of opposition, file an affidavit in support of those grounds, and serve the notices and affidavit on the applicant. Form B5 is where the person sets out, in writing, why the application or petition should not be granted.
When you need it

- You are a creditor, trustee or other person who intends to oppose an application or interim application in a bankruptcy proceeding.
- You can meet the 3-day deadline, or will ask the Court for leave at the hearing.

- 2
Opponent and capacity
Insert your name and your capacity, for example debtor, creditor or trustee, and choose application, interim application or petition.
- 3
Grounds of opposition
Set out each ground in numbered paragraphs. Keep each ground specific so the affidavit can prove it.
- 4
Affidavit and appearance
The form records that a supporting affidavit and a notice of appearance are filed with it. Prepare both: rule 2.06 requires them.

Address for service, date and sign
Give your address for service (place and email), then sign as the opponent or the opponent's lawyer and delete what does not apply.
Filing, lodging and service

- Serve the notices and the affidavit on the applicant (r 2.06(d)).
