What Is an Unexplained Wealth Order in the UK?

What Is an Unexplained Wealth Order?

An Unexplained Wealth Order is a High Court order requiring a person or organisation to explain the source of funds used to acquire a particular asset. 

The order is used where a person appears to own property or valuable assets that are disproportionate to their known lawful income. 

If the court grants a UWO, the respondent must usually provide a detailed statement explaining: 

• How the asset was acquired 
• The purchase price 
• The source of funds used 
• Any further financial information requested by the investigating authority 

Failure to provide an adequate explanation can lead to asset recovery proceedings. 

UWOs are designed to assist law enforcement agencies in financial crime investigations, particularly where the origin of assets is difficult to establish through traditional criminal investigation methods. 

The Legal Basis for Unexplained Wealth Orders

Criminal Finances Act 2017

Unexplained Wealth Orders were introduced under the Criminal Finances Act 2017, which amended the Proceeds of Crime Act 2002 to create new investigative powers.  

The legislation allows enforcement authorities to apply to the High Court for an order requiring the respondent to explain how certain assets were obtained. 

The objective is to strengthen the UK’s ability to investigate: 

• Money laundering 
• Corruption 
• Organised crime 
• Terrorist financing 

Proceeds of Crime Act 2002

If a satisfactory explanation is not provided in response to a UWO, authorities may initiate civil recovery proceedings under Part 5 of the Proceeds of Crime Act 2002. 

This process allows the court to order recovery of property believed to represent the proceeds of unlawful conduct. 

Unlike criminal confiscation proceedings, civil recovery does not require a criminal conviction. 

Who Can Be Subject to an Unexplained Wealth Order?

A UWO can only be granted if specific legal criteria are met. 

The High Court must be satisfied that: 

• The asset is worth more than £50,000 
• The respondent’s known lawful income appears insufficient to acquire the asset 
• The respondent falls within a category covered by the legislation 

Politically Exposed Persons

One category of potential respondents is a politically exposed person (PEP) from outside the European Economic Area. 

A PEP may include someone who holds a prominent public position, such as: 

• Head of state 
• Senior politician 
• Member of parliament 
• Senior member of the judiciary 
• High-ranking military officer 
• Senior executive of a state-owned company 

Close associates and family members of politically exposed persons may also be subject to UWOs. 

Individuals Connected to Serious Crime

UWOs may also apply to individuals suspected of involvement in serious criminal activity, whether in the UK or overseas. 

Examples of serious crime include: 

• Drug trafficking 
• Corruption offences 
• Fraud 
• Tax evasion 
• Organised crime 
• Modern slavery 

Importantly, a UWO may be issued even if the individual has not been charged or convicted of a criminal offence. 

How Do Authorities Obtain an Unexplained Wealth Order?

Several UK enforcement agencies can apply for a UWO, including: 

• The National Crime Agency 
• The Serious Fraud Office 
• HM Revenue and Customs 
• The Financial Conduct Authority 
• The Crown Prosecution Service 

Applications are made to the High Court. 

In many cases, the application is made without notice to the respondent, meaning the individual may not know that the authorities are seeking the order until it has already been granted. 

The court must consider whether the statutory requirements are met, including whether: 

• The asset is valued above £50,000 
• The respondent appears unable to explain the source of wealth based on known lawful income 
• The respondent falls within the relevant statutory category 

The court applies the civil standard of proof, meaning the authority must show that the criteria are met on the balance of probabilities. 

Can an Unexplained Wealth Order Be Challenged?

Yes. In certain circumstances, a respondent may challenge a UWO. 

Possible grounds for challenge include: 

• The statutory criteria were not satisfied 
• The asset value does not exceed £50,000 
• The respondent is not a politically exposed person 
• There is insufficient evidence linking the respondent to serious crime 
• The investigating authority failed to provide full and frank disclosure to the court 

Challenges are typically pursued through the High Court and require careful legal analysis of the evidence presented by the enforcement authority. 

Why Specialist Legal Advice Matters

Unexplained Wealth Orders are complex legal tools used in serious financial investigations. 

Responding to a UWO may involve reviewing financial records across more than one jurisdiction and explaining how an asset was acquired. 

Specialist legal advice can help ensure the response is properly structured, supported by evidence and prepared with the wider risks in mind. 

A defence team experienced in financial crime investigations can assist with: 

• Preparing response statements 
• Reviewing the legal basis of the order 
• Challenging the order where appropriate 
• Advising on related asset recovery proceedings 

Early legal advice can help protect your position and manage the risks connected with a UWO investigation.
