“You’re never going to see Unexplained Wealth Orders (UWOs) every day,” but this does not mean you should ignore them, Andrew Fremlin-Key, an associate at law firm Withersworldwide, has warned.

There have only been a handful of cases since their introduction in 2017, but “it will dominate your working life if a client does get served with a UWO,” he told eprivateclient.

There are four criteria that must be met for a UWO to be issued:

1. Reasonable cause to believe that the individual owns the asset.

2. The asset must be worth over £50,000.
