we were given a bit of paper by the hospital to give the registrar, it was tucked into the back of the red book. When we gave her it she said she didn't need it as their systems are conencted to the hospital's so they can see that what we're saying ties in with the hospital records, the peice of paper is only needed if the system hadn't caught up, so if we'd done it quickly or perhaps if a home birth? not sure if that's just our area though
