A petition to call on all probate service providers to be regulated in some way.
Because not all people who provide legal advice are regulated. This means they may or may not be qualified to give legal advice. They may or may not carry insurance. They may or may not sign up to any standards of professional behaviour.
Because this is a time when families are vulnerable and where financial details are being exchanged, and the public needs to have some certainty that they can trust their advisers to do a proper job (and if they do not, there will be compensation) to not sell on their details, to administer the estate as efficiently as possible, whilst taking a reasonable amount of care.
Vulnerable people should be treated with respect, and not merely fodder for the mincing machine. They need to be protected, because of their vulnerability at a sensitive time.
An unregulated business has no interest in anything but their profit, and remaining within the confines of the law. Whilst an unregulated business may choose to ascribe to a code of ethics, if that is not regulated, then how can it be enforced? There is no obligation on such a company to even profess such concepts.
