Introduction
Unexplained Wealth Orders (UWOs) are a powerful legal tool used by enforcement authorities in the UK to investigate assets that appear disproportionate to a person’s known income. Introduced under the Criminal Finances Act 2017, these orders allow investigators to require individuals to explain the origins of certain property or wealth.
For individuals facing financial crime investigations, receiving an unexplained wealth order can be a serious and complex legal matter. A UWO can lead to civil recovery proceedings and may also trigger wider criminal investigations.
Understanding how unexplained wealth orders work, when they can be issued, and how they may be challenged is essential if you are under investigation.
What Is an Unexplained Wealth Order?
An unexplained wealth order is a legal order issued by the High Court requiring an individual to explain how they obtained assets that appear disproportionate to their known lawful income.
These orders were introduced by the Criminal Finances Act 2017 to strengthen the UK’s ability to tackle money laundering, organised crime, and corruption.
A UWO does not itself confiscate property. Instead, it requires the individual to provide information about how the asset was acquired. If the explanation is unsatisfactory, enforcement authorities may pursue civil recovery proceedings to seize the asset.
UWOs are typically used as part of broader investigations into suspected financial crime.
When Can an Unexplained Wealth Order Be Issued?
A court will only grant an unexplained wealth order where specific legal criteria are satisfied.
Assets Exceeding £50,000
The property under investigation must be valued at more than £50,000.
This threshold applies to assets such as:
- Property
- Bank accounts
- Shares
- Valuable luxury items
- Other high-value assets
Suspicion of Serious Crime
Authorities must demonstrate reasonable grounds to suspect that the individual has been involved in serious criminal activity or is connected to someone who has.
Serious crime can include offences such as:
- Fraud
- Money laundering
- Corruption
- Organised crime
Politically Exposed Persons
UWOs may also be used where the individual is a politically exposed person (PEP) outside the European Economic Area, particularly where corruption risks exist.

Who Can Apply for an Unexplained Wealth Order?
Several enforcement authorities have the power to apply to the High Court for a UWO.
These include:
- the National Crime Agency (NCA)
- the Serious Fraud Office (SFO)
- HM Revenue and Customs (HMRC)
- the Financial Conduct Authority (FCA)
- the Crown Prosecution Service (CPS)
Applications are made to the High Court, which decides whether the legal criteria are satisfied.
In many cases, an unexplained wealth order is accompanied by an interim freezing order, which prevents the property from being sold or transferred during the investigation.
What Happens If You Receive a UWO?
If the High Court grants an unexplained wealth order, the recipient will be required to provide detailed information about the property in question.
This may include:
- How the asset was acquired
- The source of funds used to purchase it
- Financial documentation
- Ownership arrangements
- Information about trusts or companies connected to the asset
The response must be provided within the timeframe set by the court.
Preparing a response to a UWO can be legally complex. In many cases, extensive financial documentation and explanations are required.
What Happens If You Fail to Respond?
Failing to respond to an unexplained wealth order can have significant consequences.
If no response is provided, or the explanation is deemed inadequate, the property may be presumed to be recoverable through civil recovery proceedings.
This means enforcement authorities may attempt to seize the asset under the civil asset recovery regime.
Although UWOs are civil in nature, they frequently arise alongside wider investigations into suspected criminal conduct.
