Sworn Evidence in Family Violence Order Proceedings: How You Can Incriminate Yourself (and How s 128 Certificates Work)

Family Violence Order (FVO) proceedings are civil proceedings. That single fact lulls many respondents into a false sense of safety.

What most people are not told—by police, duty lawyers, or even some family law practitioners—is this:

Anything you say in sworn evidence in a civil FVO proceeding can be used against you in later criminal proceedings, unless you are protected by a s 128 certificate.

This is not theoretical. It happens.

Civil does not mean “safe”

FVO hearings often involve sworn oral evidence, affidavits, or answers given under oath. Although the proceeding itself is civil in nature, the rules of evidence apply, and admissions made under oath are real admissions.

Police routinely obtain transcripts, recordings, and affidavits from FVO proceedings. If your evidence contains an admission of conduct that could constitute a criminal offence, it may later be used to support a criminal investigation or prosecution.

Once you understand this, the risk becomes obvious.

A simple example that catches people out

Imagine you are asked under oath:

“Did you hit her?”

You reply:

"What do you mean by hit her? With a fist, open hand, a tennis ball? Deliberately, accidentally? Where, when, how?

They respond:

"With an open hand, last year?"

To which you reply:

“Yes, consensually with a light playful spanking in the bedroom,”

or

“Yes, but it was light sparring during self-defence training.”

From your perspective, you may think you have explained the context and negated wrongdoing.

From a criminal law perspective, you have just admitted the physical act. The only remaining question becomes consent.

If consent is later disputed—or cannot be proven to the criminal standard—your sworn admission can be enough to support a charge and, in some cases, a conviction.

This is precisely why the privilege against self-incrimination exists.

The role of s 128 of the Uniform Evidence Acts

Section 128 of the Uniform Evidence Acts (including the Evidence Act 1995 (Cth) and equivalent State and Territory Acts) modifies the common law privilege against self-incrimination for witnesses.

It applies where a witness objects to giving particular evidence on the basis that it may tend to prove that the witness has committed an offence or is liable to a civil penalty.

The law strikes a balance:

• the court can still obtain the evidence it considers necessary, but

• the witness can be protected against later use of that evidence.

That protection is delivered through a s 128 certificate.

What a s 128 certificate actually is

A s 128 certificate is a formal court-issued protection.

Once the statutory conditions are met and the witness gives the evidence, the court must “cause to be given” a certificate identifying that the evidence was given under s 128 protection.

The certificate is not symbolic. It is the mechanism that triggers legal consequences in later proceedings.

When and how it is granted

The process is typically triggered when:

• a witness (or their lawyer) objects to answering a question or giving evidence, and

• the objection is based on reasonable grounds that the evidence may incriminate them or expose them to a civil penalty.

If the court is satisfied that the objection has reasonable grounds, it may:

1. require the evidence to be given anyway, and

2. must then provide the witness with a s 128 certificate in respect of that evidence.

Crucially, the protection does not arise automatically. If you answer without objecting, you may waive the protection entirely.

What protection the certificate provides

In later proceedings in an Australian court:

• the protected evidence itself cannot be used against the witness, and

• any evidence obtained directly or indirectly as a consequence of that evidence is also inadmissible against the witness.

This derivative-use protection is critical. It prevents authorities from using your compelled evidence as a roadmap to build a criminal case against you.

The key exception: you cannot lie

A s 128 certificate is not immunity to commit perjury.

Protected evidence may still be used in a prosecution for giving false evidence. In simple terms:

• the certificate protects honest, self-incriminating evidence,

• it does not protect dishonesty.

Important limits and practical realities

A s 128 certificate:

• does not stop police from investigating,

• does not prevent charges from being laid,

• does not guarantee a prosecution will fail.

What it does is restrict what evidence can be admitted against you.

Uniform Evidence Act provisions also allow, in defined circumstances, for recognition of comparable certificates across jurisdictions, meaning a certificate issued in one State or Territory may have protective effect elsewhere.

Why this matters in FVO proceedings

FVO hearings often occur early, under pressure, and without proper advice about evidence law. Respondents are frequently encouraged to “just explain what happened” or to “be honest with the court.”

Honesty without protection can be legally catastrophic.

Before answering any question in sworn evidence that could possibly touch on criminal conduct, you must understand:

• whether the answer could incriminate you,

• whether you should object,

• and whether a s 128 certificate is required.

This is not a technicality. It is a fundamental safeguard.

Bottom line

If you are giving sworn evidence in an FVO proceeding:

• assume your words may be read by police,

• assume transcripts may be reused,

• and assume that context does not undo admissions.

A s 128 certificate can be the difference between explaining yourself safely and unintentionally handing the prosecution its key exhibit.

Family violence proceedings are not just about protection orders. They are evidence-generating environments with real downstream consequences.
