Drugs Found in a Shared House: How Does the Prosecution Prove Possession?

Drugs Found in a Shared House: How Does the Prosecution Prove Possession?

Direct answer

When drugs are found in a shared house in Victoria, the law can deem them to be in the possession of an occupier unless that person satisfies the court they had no knowledge. The prosecution relies on your occupation and the drugs being on the premises, but where areas are shared, that can be genuinely in issue.

This guide explains how the prosecution proves possession when drugs are found in a shared house in Victoria, the deemed possession rule for occupiers, what happens with shared areas, and how the charge can be defended.

About this guide

Legal basis

This guide is based on the possession offence in section 73 of the Drugs, Poisons and Controlled Substances Act 1981 (Vic) and the deemed possession provision that treats drugs on premises occupied by a person as their possession unless they show otherwise.

How this guide was prepared

Drafted for people charged after drugs were found in a shared house, based on the questions asked when the drugs may belong to a housemate.

Important limits

This article does not cover every situation. It does not specifically deal with:

  • Trafficking charges, which are far more serious
  • The precise strength of a defence on your facts
  • Drugs found in a car, which is covered separately
  • The exact current dollar value of a penalty unit
  • Commonwealth drug offences

Whether you can be convicted depends closely on where the drugs were and what you knew.

In-depth analysis

Being Charged Over Drugs in a Shared Home

Can you be charged if drugs are found in a shared house?

Yes, and an occupier can be charged even where the home is shared. Police can charge an occupier where drugs are found on the premises, because the law connects drugs on premises to the people who occupy them. Understanding how a matter reaches court helps you see how such a charge is dealt with.

That does not mean every occupier is guilty. Being charged reflects the connection between the drugs and the premises, but whether possession can be proven against you specifically is a separate question, particularly in a shared home.

What must the prosecution prove?

That you occupied the premises and the drugs were there, which can then engage the deemed possession rule. The prosecution relies on your occupation and the presence of the drugs, and from there the law can treat the drugs as being in your possession unless you show otherwise. Thinking carefully about whether to answer police matters, because your account can affect this.

The location of the drugs is important. Drugs in your own private space point more directly to you, while drugs in a shared area are harder to attribute to one occupant, which is often where a shared-house case is contested.

How Does Deemed Possession Affect Occupiers?

What is the deemed possession rule?

It is a rule that can treat drugs on your premises as yours. Where drugs are found on premises you occupy, the law can deem them to be in your possession unless you satisfy the court that you did not know they were there. This shifts the practical burden onto the occupier to answer the case. The table below shows how location affects it.

Where the drugs wereHow it is treated
In your private roomPoints more directly to your possession
In a shared areaHarder to attribute to one occupant
In another person’s roomPoints away from you

Because the rule can be answered by showing a lack of knowledge, what you actually knew is central. A genuine lack of knowledge is the key to answering a deemed possession case.

What if the drugs were in a shared area?

Then attributing them to one person is harder. Where drugs are found in a kitchen, lounge, or other common area used by several occupants, it is more difficult for the prosecution to establish that any particular occupant possessed them. Shared use cuts against exclusive possession.

This can be a real strength in a defence. If the drugs were equally accessible to several people, and there is no evidence you knew about them, the prosecution may struggle to prove the charge against you rather than a housemate.

Defending a Shared-House Possession Charge

How can you defend a shared-house possession charge?

By answering knowledge and control. The central defences are that you did not know the drugs were there, or that they were another occupant’s and not in your control, both of which can answer a deemed possession case. Where the evidence is weak, this can support charges dropped before court.

The lawfulness of the search also matters. How police entered and searched the home, and whether it was lawful, can affect the evidence. Even after a decision not to proceed, understanding if police reopen a case is worthwhile, because these matters can evolve.

What should you do if you are charged?

Get advice before giving a detailed account. Explaining a shared home without advice can concede knowledge or control you did not have, so legal advice early is important, and our work on drug offence defence starts by examining where the drugs were and what you knew.

From there, the approach is to look at the layout of the home, who used which spaces, and what you genuinely knew. A shared-house possession charge is often more defensible than it seems, because the connection between the drugs and any one occupant has to be proven.

Scenario-based guidance

If the drugs were not yours

Whose they were is in issue, so do not concede possession, and get legal advice.

If they were in a shared area

Attribution is harder, so the shared use of the space can help your defence.

If they were in another person's room

This points away from you, so it should be made clear to your lawyer.

If you did not know the drugs were there

A genuine lack of knowledge can answer the deemed possession rule.

If the search may have been unlawful

How police entered and searched can affect the evidence, so raise any concerns.

If police questioned you about the home

Be careful what you concede, because your account can affect the case.

Practical checklist

If drugs were found in your shared house:
  • Get legal advice before giving a detailed account.
  • Do not concede the drugs were yours if they were not.
  • Note exactly where the drugs were found.
  • Consider who used that part of the home.
  • Think about whether you genuinely knew the drugs were there.
  • Note who else occupies the premises.
  • Check whether the search was lawful.
  • Preserve anything relevant to the layout and use of the home.
  • Do not discuss the matter with housemates.
  • Attend every court date.

Common mistakes

  • Assuming a charge means you will be convicted.
  • Conceding the drugs were yours when they were not.
  • Giving police an account before getting advice.
  • Overlooking that drugs in a shared area are hard to attribute.
  • Ignoring the deemed possession rule and how to answer it.
  • Not noting where the drugs were found.
  • Failing to check whether the search was lawful.
  • Discussing the matter with housemates.
  • Assuming occupying the home proves possession.
  • Leaving legal advice until the day of court.

Questions to ask your lawyer

  • Can the prosecution prove I possessed the drugs?
  • How does the deemed possession rule apply to me?
  • Does it matter that the home is shared?
  • Where the drugs were found, does that help me?
  • Can I answer the case by showing I did not know?
  • Was the search of the home lawful?
  • Do I have a defence based on knowledge or control?
  • Should I contest the charge or negotiate?
  • Could the charge be withdrawn?
  • What should I avoid saying to police?

Frequently asked questions

Yes. An occupier can be charged where drugs are found on the premises, because the law connects drugs on premises to the people who occupy them. That does not mean every occupier is guilty, though, because whether possession can be proven against you specifically is a separate question, particularly in a shared home.

It is a rule that can treat drugs on premises you occupy as being in your possession unless you satisfy the court that you did not know they were there. It shifts the practical burden onto the occupier to answer the case, so a genuine lack of knowledge is central to defending a shared-house charge.

Then attributing them to one person is harder. Where drugs are found in a kitchen, lounge, or other common area used by several occupants, it is more difficult for the prosecution to establish that any particular occupant possessed them. Shared use of the space cuts against exclusive possession.

You can be charged if the drugs were on premises you occupy, but you can answer the case by showing you did not know they were there or that they were in someone else's control. Where the drugs were in another person's room, or in a shared area, that can point away from your possession.

The central defences are that you did not know the drugs were there, or that they were another occupant's and not in your control, both of which answer the deemed possession rule. The lawfulness of the search can also matter, so these charges are often more defensible than they first appear.
