The person who helped them do the will was a man who came to the house - I see his profession is Will Writer under his signature - you would have thought he would know what he is doing?
You would, but that could be a dangerous assumption to make.
Wills/tax/property with respect to giving advice can be a lethal combination for whoever is advising. If you want a bit of light reading (depressing if you're a solicitor) at this time the case of
Carr-Glynn. v Frearsons (solicitors) [1999] may be with a read. The unfortunate solicitor was found negligent when, in essence, she failed to sever a joint tenancy on behalf of her client who had expressed the desire to leave her interest in her home (held it seems jointly with her nephew) to her niece.
Depends upon viewpoint as to whether the C/Appeal decision was a bit harsh or whether the firm of solicitors deserved it.
You pays your money and takes your choice.
