Domestic violence cases don’t always come with a police complaint, a medical report, or CCTV footage attached. Abuse rarely happens with a camera running, and by the time someone considers legal action, a lot of the “obvious” proof may simply not exist. So how does a court decide what actually happened?

The answer depends on what’s before the court. An Apprehended Domestic Violence Order (ADVO) is assessed differently to a criminal prosecution, and the evidence that matters can shift depending on which one it is. We bring this blog to break down exactly what counts as evidence, so read until the end to understand what you should be gathering, and why.

How Do You Prove Domestic Violence in Court What Evidence is Needed

What Counts As Domestic Violence In NSW?

Domestic violence isn’t limited to physical assault. Under the Crimes (Domestic and Personal Violence) Act 2007, it also covers coercive or controlling behaviour, stalking, harassment, intimidation, financial abuse, sexual abuse and any conduct that causes someone to fear for their safety. It can be one incident or a pattern over time.

You also don’t need to be married for this to apply. Current or former spouses, de facto partners, and people in other intimate or domestic relationships, including housemates, carers and relatives, can all fall within the law.

How Do You Prove Domestic Violence In Court?

There’s no single piece of evidence that automatically proves a case. What matters is whether it helps establish the facts the court actually needs to decide, not simply that it exists. Depending on the circumstances, this can include:

Your Own Statement

Your account of what happened is the starting point of any case. Keeping a journal with dates, times and specific details, written as close to the incident as possible, strengthens this account considerably by the time it reaches court, and lines up well against any other evidence gathered afterwards.

Police Reports And DVEC Recordings

Since 2015, NSW Police can take a recorded statement from a complainant known as Domestic Violence Evidence in Chief (DVEC), usually taken at the scene. This recording can be played in court as the complainant’s evidence-in-chief, meaning they don’t have to verbally recount the incident again in front of the accused, though they’re still required to attend court for cross-examination.

Other police evidence that can support a case includes:

Incident reports filed at the time
Body-worn video footage
000 call recordings
Previous domestic violence complaints or attendances at the property

Witness Statements

A witness doesn’t need to have seen an entire incident for their evidence to matter. Someone who heard a threat, noticed an injury, or was told about the abuse shortly afterwards can also provide evidence that supports a case. Sworn statements carry more weight than a casual account.

Digital Evidence

Texts, emails and social media messages can help establish threats, harassment, repeated unwanted contact or admissions of behaviour. Save these as soon as they happen, screenshots with visible timestamps, backed up somewhere safe. That said, a screenshot alone doesn’t automatically prove an allegation; the court looks at what the message actually shows and how it relates to what happened.

Photographs, Videos And Audio Recordings

Photos of injuries or damaged property, ideally taken and dated soon after an incident, help establish what things looked like at the time, and follow-up photos as bruising develops can matter too. In NSW, you’re also legally allowed to record a conversation you’re part of without the other person’s consent, which makes audio recordings a genuinely useful form of evidence.

Medical Evidence

Medical records, including hospital visits, GP notes and psychologist or counsellor reports, can establish a link between alleged abuse and its impact on someone’s health. That said, this evidence isn’t required in every case; plenty of abuse leaves no physical injury at all.

Financial Records

Bank statements, records of restricted account access, and evidence of debt taken on without consent can all support a financial abuse claim. On their own, though, these records need context. A single unusual transaction, without more, doesn’t establish a pattern of control on its own.

Is Evidence Necessary When Applying For An ADVO?

Yes, evidence is essential, though how much and what kind depends on the process involved. For an ADVO, the court decides on the balance of probabilities, meaning it needs to be satisfied that it’s more likely than not that the behaviour occurred and that protection is genuinely needed. This is a considerably lower threshold than a criminal charge, where the prosecution must prove guilt beyond reasonable doubt.

It’s also worth knowing who’s responsible for gathering that evidence. If police apply for an ADVO on someone’s behalf, they prepare the supporting statements and material themselves. If a person applies privately, as outlined by Legal Aid NSW, the responsibility for gathering and presenting evidence sits with them. Either way, an ADVO isn’t itself a criminal conviction, though breaching one is a criminal offence in its own right.

What To Do If You Need To Prove, Or Respond To, A Domestic Violence Claim

If you’re building a case, start preserving evidence as early as possible. Keep records secure, report incidents to the police where you can, and speak to a lawyer well before any hearing so everything is organised properly.

On the other hand, if you’re an accused and a case is being built against you, don’t attempt to contact the protected person to sort things out directly. DVEC recordings, messages and financial records are often central to these cases, so get legal advice early and understand exactly what you’re responding to.

Concluding Words

If you’re worried that you don’t have enough evidence yet, know that the court can grant a provisional ADVO for immediate protection while a fuller case is still being put together ahead of the final hearing. You don’t need everything sorted before you seek help.

What’s gathered afterwards, though, often decides how the matter is ultimately resolved, whether that’s a final order, a withdrawn application, or a criminal conviction. Getting legal advice early means someone experienced is helping build that case properly, rather than assembling it under pressure.
