Lizzie, Good point, I believe we need legislation to enforce equal prominence to retractions etc. as was given to the original publicity, but we are not likely to get it. In view of the work involved, probably a commission of 30-40% is usually reasonable in these cases.
Estates revert to the Government if no heir can be found. Think for a moment is this a bad thing? There seems to be a trait in Britain that we want Scandanavian levels of service, paid for by North American levels of taxation. This leaves a huge gap, and miscellaneous revenue like this makes a tiny contribution to it.
Estates that go to Government do lower taxes by a tiny fraction.
