In today’s connected world, more and more family law disputes in Sydney involve digital evidence — from text messages and emails to social media posts and even location data.
While this kind of evidence can be powerful in proving (or disproving) a claim, it also raises important privacy and legal concerns in NSW.
At Barker Evans, we’ve seen firsthand how digital evidence can make or break a case — and how misuse of it can cause serious problems for the person collecting it.
Here’s what you need to know.
1. What Counts as Digital Evidence in Family Law?
Digital evidence can include:
- Text messages & emails — Conversations between parties, children, or third parties.
- Social media posts — Photos, comments, location check-ins, and status updates.
- Messaging apps — WhatsApp, Facebook Messenger, Signal, and others.
- Photos & videos — From phones, security cameras, or other sources.
- Metadata & location data — Timestamps, GPS data, and device logs.
Example: A Facebook post showing a parent on holiday during their scheduled parenting time may be used as evidence in a Sydney parenting dispute.
2. How Digital Evidence Can Be Used in NSW Family Law Cases
Digital evidence can be relevant in matters such as:
- Parenting disputes — Demonstrating behaviour, communication patterns, or breaches of parenting orders.
- Property settlements — Showing hidden assets, spending habits, or financial resources.
- Family violence matters — Proving harassment, threats, or coercive control.
Important: Evidence must be relevant and admissible under the Family Law Act 1975 and the Evidence Act 1995 (NSW).
3. Privacy Concerns — What You Can and Can’t Do
One of the biggest mistakes people make is collecting digital evidence illegally.
In NSW:
- You cannot record a private conversation without consent (Surveillance Devices Act 2007 (NSW)) unless a narrow exception applies.
- Accessing someone else’s phone or email without permission can be illegal.
- Hacking or using spyware is a criminal offence.
Using unlawfully obtained evidence can harm your case — and may even result in charges against you.
4. Social Media — Friend or Foe?
Social media posts are often used as evidence in Sydney family law cases — sometimes in surprising ways.
- Posts showing expensive purchases during a financial dispute
- Public criticism of the other parent, affecting parenting arrangements
- Inconsistent statements compared to evidence given in court
Tip: If you are in the middle of a family law matter, review your privacy settings, limit what you post, and avoid discussing your case online.
5. Best Practices for Handling Digital Evidence
To protect your rights and strengthen your case:
- Keep communications respectful and factual — assume every message could be read in court.
- Save copies of relevant messages or posts before they can be deleted.
- Note the date, time, and context of any evidence.
- Get legal advice before collecting or sharing sensitive material.
6. Why Legal Guidance Matters
Every case is different, and digital evidence rules in NSW family law are complex. What seems helpful to you could be damaging if used incorrectly.

- Assess whether your digital evidence is relevant and admissible
- Advise on lawful ways to collect and preserve it
- Present it effectively to support your case while protecting your privacy
