Introduction
Unexplained Wealth Orders, often called UWOs, are used by UK enforcement authorities to investigate assets that appear out of step with a person’s known lawful income. Introduced under the Criminal Finances Act 2017, they allow investigators to require an individual to explain how certain property or wealth was obtained.
Receiving a UWO can be a serious matter, especially where it forms part of a wider financial crime investigation. It may lead to civil recovery proceedings and, in some cases, further investigation into suspected criminal conduct.
If you are facing a UWO or believe one may be sought against you, it is important to understand what the order requires, when it can be made and how it may be challenged.
What Is an Unexplained Wealth Order?
An Unexplained Wealth Order is a High Court order requiring a person 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, by itself, confiscate property. It requires the recipient to provide information about how the asset was acquired. If the explanation is not provided, or is considered unsatisfactory, enforcement authorities may seek to recover the asset through civil recovery proceedings.
UWOs are usually used as part of wider 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 show 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, known as a PEP, outside the European Economic Area, particularly where corruption risks are alleged.

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, a UWO may be accompanied by an interim freezing order. This can prevent the property from being sold or transferred while the investigation continues.
What Happens If You Receive a UWO?
If the High Court grants a UWO, the recipient must provide detailed information about the property named in the order.
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 UWO response can be complex. It may require detailed financial records, clear explanations and careful consideration of the wider legal risks.
What Happens If You Fail to Respond?
Failing to respond to a UWO can have serious 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 orders, they often arise alongside wider investigations into suspected criminal conduct.

Can an Unexplained Wealth Order Be Challenged?
Yes. A UWO may be challenged through legal proceedings.
Possible grounds may include:
- Failure to meet the legal criteria
- Insufficient evidence linking the asset to suspected criminal conduct
- Procedural errors in the application
- Issues with asset ownership assumptions
Challenges can involve detailed financial records and complex evidential issues. The approach will depend on the facts of the case and the evidence relied on by the enforcement authority.

These investigations often sit within wider financial crime enquiries and may involve more than one enforcement agency.
Specialist legal advice can assist with:
- Reviewing the legality of the UWO application
- Preparing a response to the court
- Protecting assets during investigations
