Er...what was the question again ? If I have the time, in absentia Barmaidiae, I'll dive into Inner Temple library and dig out some authorities (or,more likely, ring the senior wills and probate partner in my sols; dammit, I've paid her enough over the years, about time she did something free !)
Thanks for the good wishes re the racing. Derby day sounds ominous. I'm taking my daughter, who has just said "I haven't even got a dress yet. Shall we meet at Peter Jones at half past ten?" All fathers of young daughters know what that means; at least a hundred quid down before I even get to Epsom!
