It is important that consumers are aware of their rights concerning their wills, it has been noted.
The Office of Fair Trading (OFT) pointed out that it is possible for individuals to appoint either a professional or a lay person to administer their estates in the event of their deaths.
Friends or family members who are selected for such purposes can choose to be assisted by a professional if they wish when the time comes.
The organisation - which is independent and aims to make markets work well for consumers - made its remarks after the Solicitors Regulation Authority published new guidance on the subject.
Director of services at the OFT David Stallibrass stated: "Preparing a will is important to make sure that your wishes are respected after your death."
He added that consumers should be able to make an informed decision about who they select as an executor in the legal document.
