Our expert solicitors deal with challenges against lifetime gifts or transactions that may be a result of financial abuse.
While such assistance can be informal, it’s often undertaken by attorneys or deputies that have been appointed formally by the person needing help (or by the court). Sadly, this can make people vulnerable to exploitation — and with two in five British adults (Aviva, 2023) experiencing financial or economic abuse, this happens more often than you might think.
Financial abuse often involves a trusted person treating another’s money as if it’s their own. This can range from using their bank card to transferring large sums of money (or even property) for the benefit of themselves or people connected to them. One form of financial abuse is known as predatory marriage.
If you have questions or concerns about whether someone’s finances are being handled properly or resources are being used for other means, it’s important to seek advice. Our experienced financial abuse solicitors are often asked to advise in circumstances where suspicions have been aroused — either during the lifetime of the alleged victim or after they’ve passed away. While this can prove to be unintentional mishandling or mismanagement, more serious cases can involve the intentional misuse of a person’s finances.

According to Age UK, financial abuse is the “mistreatment of someone in terms of their money or assets, such as their property”. This includes situations where monies are being stolen, misused or access to assets are being restricted.
While financial abuse can take many forms, it often arises where the victim is being assisted with aspects of daily living, such as shopping or care services.
The most obvious signs to look out for are:

It can be difficult to prove financial abuse — particularly where the abuser has legitimate access to a victim’s assets. For example, where they are an account signatory or have authority under a Lasting Power of Attorney.
Since the ‘abuser’ is usually someone in a position of trust — such as a family member, ‘friend’ or carer — financial abuse can be difficult to identify.
In most cases where financial abuse is suspected, a report would usually be made to the police and bank (if appropriate) so that investigations can be carried out. It may also be necessary to make a report to Social Services and the Office of the Public Guardian where the abuser is acting under a Lasting Power of Attorney or Deputyship Order.
It’s easier to obtain proof of the abuse where the victim remains living, as (for example) they’ll be able to provide direct evidence regarding any unauthorised or suspicious transactions. This may include obtaining bank statements and witness statements.
Where a victim has died, things can become complicated due to strict data protection and disclosure rules, which can be difficult to navigate.
