There are many UK consumers who are lacking wills, a professional advice website has claimed.
According to Unbiased.co.uk, 28 million Britons are without such legal documents, meaning their estates may not go to the parties they would wish in the event of their deaths.
The organisation also found that 65 per cent of people with children under the age of 18 have not drawn up a will.
It pointed out that failing to do so means consumers' estates are likely to be charged more tax than if they planned their finances in a will.
Chief executive of Unbiased.co.uk Karen Barrett said: "If you haven't a will your only legacy could be to leave a large inheritance tax bill for your loved ones."
She added that by having such documents in place, families can reduce the worry and stress they experience at an "already difficult time".
Recently, legal expert Adam Draper suggested that there has been a rise in the number of people disputing the details of wills as family structures have become more complex, the Birmingham Post reported.
