You have been the victim of a robbery + greed and I'm sorry to say you do not have much redress because the Solicitors so called Complaints Board is there to protect Solicitors and to tell you to xxxxx xxxooo, sorry I meant to say wear you out. You will wait patiently 9 months for a reply, and being human you'll imagine these little complaint board beasties will have your interests at heart, but you'll get a very professional 2 page letter if your lucky, saying "We have investigated the matter, and in our opionion Baron Greed of Twiddle Le thumbs is actually well within the law and fees scale we recommend, he tells us had huge problems with this estate [and a lot more more problems when he was sober] that needed extra effort and dedication like phoning up the council twice to ask them for a letter telling him that there's was no outstanding taxes owing on the property, and in the circumstances outlined to us by him his fee is more than reasonble," and dont you ever think of suing him because 6 years was reasonable in the circumstances. Don't you know that Solicitors have codes of conduct to follow and would'nt dream off overcharging clients, especially if their long dead and buried. And haven't you heard of probate success fees, you have'nt then you ought to do a Google search on the subject. And keep an eyeon on your aunts old house and watch for it being resold 'on the open market soon for a better price'. Even auctions can be rigged you know?
