If they are anything like the "bonds" my mother had from a building society when she died, I got them passed into my name as executor because they would have paid nothing for the years already run if cashed in at the time. When they matured I got the building society to pay them out in a number of cheques so my siblings and I could have what we were left in mother's will. Some time later I had the tax man claiming I'd not declared something but thinking it great fun, an absolute hoot, not to say what. Racked my brain for ages, then finally it occurred to me. Surely he could not possibly have been referring too those bonds that had already been covered by the estate that was too small to attract a tax demand ? Turns out it was ! Luckily I was able to convince him that it wasn't mine but part of the estate, delayed, but that's the sort of stress we all could do without.
