I’ve mentioned Kenneth Adams on contract drafting twice before.
He will be giving a one-day seminar on legal language in Frankfurt am Main on April 26, and before that on April 17 in London and April 19 in Paris. More information on seminars here and here. I see he gives a ‘rigorous overview’, so everyone should be happy. The seminars are primarily for lawyers and take both U.S. and British usage into account.
