Hello, I am trying to fill out the probate PA1 form for my nan's estate and I'm stuck on section B4 as her family were a bit rubbish at keeping in touch. The questions are as follows:
A - Brothers and sisters who survived the deceased - definitely none
B - Brothers and sisters who did not survive the deceased - pretty sure it is 7
C - Children of those in 4B who survived the deceased - this is where it gets tricky, I know of 5, but there could be more. Can I put 'unknown' or 5 in this box or do I have to know for sure? (there is a will, so doesn't matter anyway)
