Can Social Media Posts Be Used As Evidence In Court?

From Facebook updates to Instagram photos and private messages, our online activity may often feel harmless. However, when you're involved in family law or criminal law court proceedings, what you post online can have serious legal consequences. A single online image or status update can now strengthen or weaken a defence.
Australian courts, including the Family Court and Federal Circuit and Family Court of Australia, have shown a willingness to accept social media content as evidence where it is relevant. Screenshots of posts, comments, messages, photos and even deleted content are increasingly being included in affidavits and relied upon in criminal, parenting, property and spousal maintenance matters.
Simply put: anything you share online can be closely examined, tested and potentially used against you.

What Types Of Social Media Posts Can Be Used As Evidence?
There is no concrete rule about which social media posts can be used as evidence. Instead, courts assess each case (and each post) on a case-by-case basis, considering its relevance, reliability and the context in which it was shared.
Courts may accept a wide range of social media content, including:
Facebook and Instagram posts
Photos and videos
Comments, reactions and stories
Private messages and group chats
Location check-ins and timestamps
These posts may be used to support claims about your behaviour, lifestyle, finances, relationships or parenting capacity, even if you believe they do not reflect the full picture.
Self-Incrimination
Even content that appears harmless, such as a casual post, photo or TikTok, can undermine your account of events or place you near an alleged crime scene. Prosecutors frequently rely on these digital footprints to construct timelines or suggest involvement where traditional evidence may be limited or unavailable.
Parenting And Character Evidence
Negative comments about a former partner are frequently relied upon in parenting disputes. Courts place significant importance on each parent’s ability to support the child’s relationship with the other parent. Hostile or critical posts can undermine this and may be used to suggest an inability to co-parent effectively.
Photos and videos can also be powerful. An image of social drinking, a weekend away, or a night out may be presented as evidence of poor parenting judgment or lack of child-focused behaviour.
Financial Capacity
Holiday photos, luxury purchases, or lifestyle posts can be used to argue that a party has a greater financial capacity than they claim. In property settlements or spousal maintenance matters, these posts may be relied upon where other financial evidence is limited.
Because non–child-focused behaviour often occurs behind closed doors, social media content is increasingly being used as primary evidence where there may otherwise be little to rely on.
Posting About Court Proceedings Is A Serious Risk
You should never post about your criminal or family law proceedings on social media or any public forum.
Section 121 of the Family Law Act 1975 makes it a criminal offence to publish or disseminate information that identifies a party to family law proceedings, or a person associated with them. This includes publication by electronic means, such as social media.
Breaching section 121 can carry serious consequences, including criminal penalties.
Can Social Media Ever Help Your Case?
While social media often creates risks in legal proceedings, it may assist a case if used carefully and lawfully. When properly obtained and presented, social media content may help clarify events, test the accuracy of another party’s evidence, or provide important context that might otherwise be missing.
Depending on the circumstances, social media posts may be used to:
demonstrate inconsistencies in their evidence
establish timelines or conduct relevant to the issues before the court
However, whether a post can be used in Court depends on whether it is genuine, relevant, and obtained legally. Courts will closely examine whether the content has been edited, taken out of context, or collected improperly.
Essential Social Media Rules During Family Law Proceedings
If you are involved in a family law dispute, always consider the following best practices:
Do not post about your case, your former partner, or your children
Avoid deleting old posts, as this may be viewed as attempting to destroy evidence
Assume everything is discoverable, even private messages
Avoid tagging, check-ins and location sharing
Do not engage in arguments or emotional posts
Do not share court documents or correspondence
When in doubt, say nothing and seek legal advice
It's important to remember that deleted social media posts and private messages may still be recoverable through subpoenas and other lawful court orders. Whilst data retention policies will differ from platform to platform, deleted data is often available for months or even years after.
Taking a temporary break from social media during family law proceedings is often the safest course of action. This way, you reduce the risk that something you say or share could be misinterpreted or used against you in Court. This pause also allows you to focus on the legal process without distractions and ensures that any online activity is carefully considered and compliant with legal obligations.
